1. General Drinking Water System Information

1.1 Where does the water come from?

The South Peel Drinking Water System supplies a population of over 1.4 million people in the

Cities of Brampton and Mississauga and the southern parts of Caledon, including the community

of Bolton. A portion of water produced is also supplied to York Region.

Raw water from Lake Ontario is pumped into two surface water treatment plants, Lakeview Water

Treatment Plant (WTP) and Lorne Park Water Treatment Plant (WTP), from intake pipes

extending as far as two kilometres off shore. The Lakeview and Lorne Park plants are owned by

the Region of Peel and operated by the Ontario Clean Water Agency (OCWA). In 2017, these

plants produced over 208 billion litres of water. Both plants are classified by the Ministry of the

Environment and Climate Change as Class IV water treatment subsystems.

Distribution System / Storage Facilities

The South Peel Distribution System is comprised of a Class IV transmission and pumping

subsystem made up of water storage facilities, large diameter feedermains and pumping stations

for bulk water movement, and a Class II distribution subsystem made up of a large network of

distribution watermains. The distribution system carries water from the treatment plants to the

Cities of Brampton and Mississauga and parts of Caledon through a series of pipes that range in

size up to 2100 mm (approximately 7 feet) in diameter. There are a total of 13 reservoirs, 4

elevated tanks, and 2 standpipes in the South Peel Drinking Water System.

The South Peel Distribution System consists of the following components: 4,350 km of

watermains, 45,851 mainline valves, 27,045 fire hydrants and 319,803 water services. (2017- South Peel Water Distribution System)

2. How is Water Treated?

2.1 Lakeview Water Treatment Plant (Drinking Water Works Number 210000568)

Located on the north shore of Lake Ontario, the Lakeview Water Treatment Plant (WTP) serves

primarily the east side of Mississauga and Brampton, as well as parts of Caledon, including the

community of Bolton, and provides water to York Region. Lakeview WTP is comprised of three

treatment processes: a conventional water treatment plant and two advanced treatment plants

consisting of ozone, biologically active carbon contactors and membrane filtration, one

additionally using ultraviolet (UV) light disinfection. The Lakeview Water Treatment Plant is

capable of producing up to 1,150 million litres of treated drinking water per day.

Figure 1: Lakeview Water Treatment Plant

10

Conventional Treatment

Conventional treatment consists of the following steps: coagulation, flocculation, sedimentation,

filtration, plus chlorine disinfection. Refer to Section 2.3 for a detailed description.

Ozone, Biologically Active Carbon Contactor and Membrane Filtration (OBM) Treatment

The OBM treatment process consists of ozone, biologically active carbon contactor (BACC)

treatment and membrane filtration. Refer to Section 2.4 for a detailed description.

Refer to Figure 2 for the Lakeview Water Treatment Plant Process Diagram.

The treatment additives and other products used at the Lakeview Water Treatment Plant during the

reporting period were:

aluminum sulphate (alum) – a coagulant to aid tiny particles in the water to join together to form larger particles that are easier to settle and/or filter out chlorine gas – used to disinfect the water citric acid, sulphuric acid and water softener salt – used to clean the membrane filters sodium hydroxide – used to neutralize the spent membrane cleaning solution sodium hypochlorite – used to clean the membrane filters and discourage mussel growth in the intake pipe hydrofluosilicic acid – used to optimally fluoridate the water to prevent tooth decay liquid oxygen – used to generate ozone gas on-site. Ozone is a strong disinfectant. sodium bisulphite – used to quench residual chlorine and ozone anionic polymer and cationic polymer – used in the wastewater stream to settle out solids

The west side of Mississauga and Brampton is serviced primarily by the Lorne Park Water

Treatment Plant. Several watermains allow water to transfer from either east to west or west to

east. Refer to Figure 5 for the South Peel Water Distribution System Flow Chart.

2.2 Lorne Park Water Treatment Plant (Drinking Water Works Number 210001317)

The Lorne Park Water Treatment Plant (WTP) supplies water to primarily the west side of

Mississauga and Brampton and it is located on the north shore of Lake Ontario, largely

underground beneath public park land. Lorne Park WTP has two treatment processes: a

conventional treatment plant with ultraviolet (UV) light disinfection, and an advanced treatment

plant consisting of membrane filtration, UV light, and granular activated carbon contactors

(GACC). The Lorne Park Water Treatment Plant is capable of producing up to 500 million litres

of treated drinking water per day.

2.3 Conventional Water Treatment Process Description

Both Lakeview and Lorne Park WTPs employ conventional treatment processes.

Lake Ontario is the source for the South Peel Drinking Water System. As the lake

water enters the intake pipe, it can be chlorinated. The chlorine kills bacteria and

discourages mussels from growing in the intake pipe and obstructing the flow.

As the water enters the treatment facility, it passes through travelling screens. The

screens prevent items such as fish, sticks, shells, and aquatic plants from entering

the treatment facility and damaging equipment.

Low lift pumps draw the lake water into the treatment plant.

Coagulation assists with the removal of turbidity and suspended matter

(particles) from the water. A coagulant (Alum or ACH) is added to the

water. The rapid mixer thoroughly mixes the coagulant with the water to help

form sticky particles.

Flocculation is the process of slow mixing that helps the sticky

particles collide with each other, forming larger and heavier

particles called floc.

In the sedimentation process, floc particles are removed from the water by inclined plate settlers

(as used at Lorne Park WTP) or the water is slowed down in large tanks

(used at Lakeview WTP) to allow particles to settle to the bottom. The

settled solids are removed and transferred to the wastewater treatment

facility.

http://www.peelregion.ca/pw/water/sewage-trtmt/wastewater-trtmt.htm

http://www.peelregion.ca/pw/water/sewage-trtmt/wastewater-trtmt.htm

16

Conventional filtration removes particles and bacteria that were not settled out in the previous

step and filters using GAC media can reduce the quantity of

compounds that can cause unpleasant tastes and odours. The water

filters through layers of granular activated carbon (GAC) or

anthracite, sand and gravel. Water starts at the top of the filter and

moves down between the granules by gravity.

Note: by the end of 2017 all conventional filters at the Lakeview Water Treatment Plant have been

converted from GAC to anthracite media.

When needed, the filters are backwashed (cleaned). Clean water is pumped up and through the

filter media, in a reverse flow, lifting and flushing out the floc particles that have accumulated in

the filter. The backwash water is treated in the process wastewater treatment facility prior to being

discharged to the lake.

The process of disinfection destroys or inactivates harmful disease-causing organisms such as E.

coli and Giardia. Chlorine is the most common disinfectant used in water treatment.

Fluoride is added to the finished water to prevent cavities in our teeth. The finished water is then

stored in a reservoir and distributed to the customers through a series of pumping stations and

reservoirs.

Diesel-powered generators provide auxiliary or standby power for the facility. Standby power

ensures we can provide water in case of an emergency such as a massive power failure.

The water flows through watermains to houses, apartments, schools, and commercial and

industrial premises. Refer to Figure 5 for the South Peel Water Distribution System Flow Chart.

2.4 Ozone, Biologically Active Carbon, and Membrane (OBM) Water Treatment Process Description (Used at Lakeview WTP)

Low lift pumps draw water from Lake Ontario into the treatment plant.

Ozone gas is generated on site from liquid oxygen and electricity. The ozone is bubbled through

the water in the ozone contactors. Ozone kills bacteria and also

helps to break down substances that cause tastes and odours so

that they are more easily removed in the next treatment step.

The water then passes into the biologically active carbon contactors (BACC). These contactors

remove the biodegradable organic matter produced by the activity of

the ozone process. The BACCs are very good at adsorbing organic

matter from the water and this removal process keeps the water stable

after treatment by minimizing re-growth of bacteria in the distribution

system.

The Lakeview Water Treatment Plant has two OBM treatment plants.

OBM2, commissioned in 2014, has one additional treatment step that OBM1

does not have: ultraviolet (UV) light. The specific wavelength of light

emitted by these UV units inactivates microorganisms so that they cannot

reproduce and cause infections.

In the next treatment process, water passes through the ultra filtration

membrane system. These are specially designed water filters with

very small pores that the water is pulled through. The membrane

filters are so effective that they are capable of removing

microorganisms and producing water with very little turbidity.

18

Filtered water is directed to the weir box. The weir box stores water and is also the

location where chlorine and fluoride are added.

Chlorine and fluoride are added to the treated water from both the conventional treatment and the

OBM treatment processes as it flows by gravity into the water storage

reservoir. The water must remain in the storage reservoir until adequate

disinfection has occurred. Water leaves the reservoir by way of High Lift

Pumps and enters the distribution system.

2.5 Membrane, Ultraviolet Light, and Granular Activated Carbon (MUG) Water

Treatment Process Description (Used at Lorne Park WTP)

Low lift pumps draw raw water from Lake Ontario into the treatment plant.

Raw water is pulled through ultra filtration membranes with pores small

enough to filter out particles and many microorganisms.

Filtered water then passes through ultraviolet (UV) light units, which inactivate microorganisms,

for disinfection of the water. These UV units can also be used for a

process called advanced oxidation, which uses hydrogen peroxide,

added upstream of the UV units, and a higher intensity of UV light to

oxidize (break apart) substances that cause tastes and odours. The

advanced oxidation process is used seasonally, when taste and odour problems are at their peak

due to lake conditions.

19

The water then flows into granular activated carbon contactors (GACC), where it moves by

gravity down through a matrix of carbon granules. The GACCs eliminate

any residual hydrogen peroxide remaining from the advanced oxidation

process.

Chlorine and fluoride are added to the water on its way into the on-site storage reservoir, from

which it is pumped into the distribution system.

2.6 South Peel Water Distribution System (Drinking Water System Number 260094120)

The drinking water in the South Peel Distribution System is re-chlorinated using sodium

hypochlorite at the North Brampton Pumping Station, Airport Road Pumping Station, and Bolton

South Booster Pumping Station and chlorine gas at the Beckett Sproule Pumping Station.

Drinking water being directed to York Region is chloraminated at the Airport Road Pumping

Station by adding sodium hypochlorite and aqua ammonia at a specific ratio. Refer to Figure 5.

3. Region of Peel and Drinking Water Compliance in Ontario Drinking water quality in Peel is regulated by the Ontario Government through the Ministry of the

Environment and Climate Change (MOECC). The Ontario drinking water legislation sets

requirements for municipal system owners and operating authorities with regards to operation and

management, level of treatment, sampling and testing, training and certification of staff, and water

quality notification.

3.1 Annual Water Reports

To comply with the Drinking Water Systems regulation (Ontario Regulation 170/03) under the

Safe Drinking Water Act, 2002, every year, Peel prepares Water Quality Reports that provide

information on quality of water supplied and a Summary Report covering the operation and overall

performance of the drinking water systems.

The Summary Report under Schedule 22 of the Ontario Regulation 170/03 includes a statement of

compliance with the Safe Drinking Water Act, 2002, the regulations, and the terms and conditions

of all the approvals for Peel’s drinking water systems. It also includes a summary of the quantities

and flow rates of water supplied to assess the capability to meet the existing and planned uses of

the water systems. This report is made available to Regional Council by March 31 of each year.

The Water Quality Reports and the Summary Report are made available to the public to ensure

Peel consumers are kept informed. Each year, the reports are posted on the Region of Peel’s web

site (http://www.peelregion.ca/pw/water/quality/reports/) and their electronic or paper copies may

be obtained upon request by emailing the Region at [email protected] or

calling at 905-791-7800 ext. 4685.

Additionally, an ad is placed in the local newspapers to inform the consumers about the

availability of Peel’s Water Quality Reports.

http://www.peelregion.ca/pw/water/quality/reports/


22

3.2 Sampling and Testing

In compliance with the drinking water legislation, drinking water systems are required to monitor

the water quality of drinking water to ensure it meets provincial standards.

Peel regularly samples and tests raw, treated and distribution system water for a number of

microbiological, chemical, physical, and radiological parameters. Peel has always had an extensive

water sampling and monitoring program to better understand the quality of source water, to ensure

effectiveness of treatment processes, and to diligently monitor and protect the drinking water

supply. Sampling and testing is conducted by trained and qualified operators, who collect water

samples from various sampling sites throughout the Region and immediately test them for first

water safety indicators. As part of Peel’s water quality monitoring programs, samples are

collected for laboratory analysis for a vast number of health-related and aesthetic parameters.

The Ministry of the Environment and Climate Change (MOECC) requires that all drinking water

testing laboratories be accredited by the Standards Council of Canada (SCC) based on proficiency

evaluation conducted by the Canadian Association for Laboratory Accreditation (CALA) as well

as licensed by the MOECC for all drinking water tests performed. All laboratories used by Peel are

accredited by the SCC, licensed by the MOECC, and adhere to strict drinking water sample

collection, handling and transport protocols as well as analytical methods and reporting

procedures.

3.3 Certified Water Operators

All water treatment plant, distribution system and maintenance operators and technical staff have

appropriate Water Treatment, Water Distribution and Water Quality Analyst certification, as

required by the Ontario drinking water legislation. The MOECC-mandated training and

certification program ensures that all operators are certified to industry recognized standards. Peel

has established a continuing education program for all staff responsible for operating drinking

water systems. The program features in-house training that addresses Peel’s specific needs with

focus on the operation and management of Peel-owned drinking water systems and that offers the

23

benefits of increased staff engagement through a custom designed training toolkit tailored to our

business mandates. This helps the operators to gain knowledge of the latest industry practices,

technologies and advanced processes and to effectively maintain system water quality and

quantity.

3.4 Water Quality Notification

In compliance with the regulatory requirements, Peel reports every event of adverse water quality

to the Medical Officer of Health and the MOECC, and initiates timely corrective action to address

and resolve the issue and implement control measures to prevent its recurrence. Peel has

established a notification protocol for reporting of adverse water quality events and makes these

reports and data publicly available in the Water Quality Reports. A summary of reportable events

in 2017 for the South Peel Drinking Water System may be found in Section 4 of this report.

3.5 Water System Inspections

On an annual basis, Peel’s drinking water systems undergo the MOECC inspection program to

confirm compliance with provincial drinking water legislation. The MOECC’s annual inspection

program is an important aspect of drinking water supply to our consumers. Through this program,

the Ministry ensures that Peel meets the sampling, testing and disinfection requirements, treatment

standards, terms and conditions of all Ministry approvals, and staff certification and training

requirements as stated in the Ontario Regulations 170/03, 169/03, and 128/04 under the Safe

Drinking Water Act, 2002.

MOECC inspections provide Peel with an overview of how well our drinking water systems are

doing and how well we meet the province’s stringent regulations. They also provide an opportunity

to review our best management practices and, if necessary, implement new processes to

continually improve the operation and management of Peel’s drinking water systems.

For an overview of all the work the MOECC is doing to protect drinking water in Ontario, please

visit the MOECC website for the Minister of the Environment and Climate Change report:

24

https://www.ontario.ca/page/ministers-annual-report-drinking-water-2017 4. How well did we do?

4.1 Operation

To protect the health of the public and to ensure consumers receive clean and safe drinking water,

the Ministry of the Environment and Climate Change (MOECC) has established the Ontario

Drinking Water Quality Standards that make up Ontario Regulation 169/03. These standards are

set to ensure the water is free of disease-causing organisms and harmful or radioactive chemicals

and are reviewed from time to time based on new science and to keep them aligned with the

Canadian Drinking Water Quality Guidelines.

Ontario Regulations 169/03 and 170/03 were amended in 2015. Effective January 1, 2017, there

are new, lower limits for benzene, carbon tetrachloride and vinyl chloride, as well as a new

quarterly sampling requirement for haloacetic acids (HAAs). Additional amendments are being

phased-in over the next four years to allow drinking water system owners and operating authorities

time to collect baseline information and prepare for any necessary treatment process upgrades. The

changes that became effective in 2017 are reflected in Appendix A of this report.

In 2017, Peel monitored water quality by undertaking tens of thousands of process samples and

tests to ensure a safe and clean water supply. Appendix A provides a summary of the water quality

test results.

The MOECC performs annual inspections on all municipal drinking water systems and based on

the inspection findings, the Ministry issues score cards. The score relates to the information and

data review covered by the Ministry Inspector during each inspection. The South Peel drinking

water systems’ overall performance is high, as presented in Figure 6.

5. Drinking Water Quality Programs

5.1 Municipal Drinking Water Licensing Program

Under the Safe Drinking Water Act, 2002 (SDWA), all municipal residential drinking water system

owners in Ontario must have a Municipal Drinking Water Licence (MDWL) to operate their

system(s). In order to be issued a Licence, the Ministry of the Environment and Climate Change

(MOECC) requires owners to have the following five prerequisites:

I. Drinking Water Works Permit (DWWP)

A permit describing the drinking water system and giving authority to establish or alter a drinking

water system. Peel holds a valid DWWP for each of its five (5) drinking water systems.

II. Permit to Take Water (PTTW)

A valid permit to take water issued under the Ontario Water Resources Act (OWRA) specifying

the approved rate of water taking. Peel holds a valid PTTW for each of its drinking water sources.

III. An Accepted Operational Plan

The Operational Plan defines and documents the Quality Management System (QMS) for Peel’s

drinking water systems in accordance with the requirements of the MOECC’s Drinking Water

Quality Management Standard (DWQMS). The Operational Plan outlines the policy commitments

and associated procedures, responsibilities and evaluation criteria that ensure drinking water

quality and safety in all processes for water treatment and distribution, from source to tap.

IV. Accredited Operating Authority (Third-Party Audit of the QMS)

Municipal residential drinking water system owners must ensure that at all times, an accredited

operating authority is in charge of the drinking water systems. Peel owns five large municipal

residential drinking water systems. As the operating authority of the South Peel Distribution

System, as well as four groundwater systems in Caledon (Caledon Village - Alton, Cheltenham,

Inglewood, Palgrave - Caledon East), Peel became an accredited Operating Authority in August

31

2011, and has been successfully maintaining this mandatory accreditation. The Ontario Clean

Water Agency (OCWA), under contract, operates the Lakeview and Lorne Park Water Treatment

Plants as well as the South Peel Transmission and Pumping System. OCWA has been, and remains,

an accredited Operating Authority since July 2013.

Full Scope Accreditation recognizes that the operating authority has a QMS in place that conforms

to the DWQMS as documented in the Operational Plan.

The MOECC has designated two accreditation bodies under the SDWA and Peel has worked with

the third-party auditor, SAI Global, who provides accreditation auditing services. Continuance of

accreditation is based on a three-year review cycle comprised of annual offsite surveillance audits

in years one and two; and an offsite systems audit, followed by an onsite accreditation audit in year

three. The onsite verification audit for DWQMS reaccreditation was completed by SAI Global in

February 2015 and included documentation and records review, facility tours and interviews with

staff. Peel achieved full conformance to DWQMS and the current certificate of accreditation,

valid for three years, expires March 2018. The year one and year two surveillance audits under the

new certificate cycle were conducted in February 2016 and February 2017, respectively. The

audits confirmed Peel’s full conformance to the DWQMS, and identified areas to review and

further enhance the internal audit processes.

V. Financial Plan

Ontario Regulation 453/07 Financial Plans mandates municipal drinking water system owners to

prepare a long term strategy to ensure the financial sustainability of drinking water systems. The

Financial Plan for the drinking water systems was first prepared and approved by Council

Resolution in June 2010 and submitted to the Ministry of Municipal Affairs and Housing

(MMAH). The Financial Plan forecasts a period of at least six years and, at a minimum, must be

updated and approved by Council Resolution and resubmitted to the MMAH every five years prior

to an application for the renewal of the municipal drinking water licence. Pursuant to the

32

municipal drinking water licence renewal applications, an update to the Financial Plan was

prepared by staff for Regional Council’s endorsement. The Financial Plan (2014-2019) was

adopted by Regional Council in April 2014 and submitted to the MMAH satisfying the

requirements under Ontario Regulation 453/07.

Summary of Approvals and Permits

Peel holds valid approvals and permits, has satisfied all DWQMS accreditation requirements of the

Municipal Drinking Water Licensing Program, and has been operating all its municipal drinking

water systems in accordance with the approvals framework under the SDWA. Municipal drinking

water licences are valid for five years. To ensure continued authority to operate, owners are

required to renew the licences before the expiry date and renewal application deadline. Peel

submitted applications for licence renewal in May 2014 and new licences were issued for each

municipal drinking water system in November 2014. Peel’s current municipal drinking water

licences are due to renew in May, 2019.

To ensure a licence remains current, amendments and reissues occur from time to time to reflect

alterations to the drinking water system and/or changes to system-specific conditions.

5.2 Source Water Protection The Clean Water Act, 2006, (the ‘Act’) came into effect on July 3, 2007, with the promulgation of

the initial set of source water protection regulations. The focus of the legislation is to protect

existing and future municipal sources of drinking water. The source protection process is driven

by locally-based Source Protection Committees comprised of appointed representatives from

municipal, industrial, commercial and agricultural sectors and the public at large. The Region of

Peel falls under the jurisdiction of three Source Protection Authorities as follows:

http://www.peelregion.ca/pw/water/quality/dwqms-peel.htm

33

• Credit Valley-Toronto-Central Lake Ontario (CTC) Source Protection Authority (SPA);

most of Peel’s groundwater and surface water intakes fall within this SPA

(www.ctcswp.ca)

• South Georgian Bay Lake Simcoe (SGBLS) Source Protection Authority; only Palgrave

Well No. 3 falls within this SPA (www.ourwatershed.ca)

• Halton-Hamilton (H-H) Source Protection Authority; none of Peel’s groundwater systems

or surface water intakes lies within this SPA (www.protectingwater.ca)

Region of Peel has participated in the initial phases of source protection planning by carrying out

technical studies for assessment reports and policy development through representation on the

Source Protection Committees and working groups whose work led to the development of the

Proposed Source Protection Plans.

The Source Protection Plans, for the CTC, SGBLS and H-H SPAs, which include the monitoring

and reporting policies for all significant, moderate and low drinking water threats, were approved

by the Minister of the Environment and Climate Change in 2015. The effective date for the CTC

and H-H Source Protection Plans is December 31st, 2015, and the SGBLS Source Protection Plan

effective date is July 1st, 2015.

Peel is working on implementing the source protection plan policies to meet the requirements of

the Act. In 2017, a new Risk Management Official, an alternate Risk Management Official and a

secondary Risk Management Inspector were appointed by Council to ensure continued program

continuity and coverage at all times.

A comprehensive database management, filing and records keeping system have been developed

using internal resources. These business processes have been in effect since April of 2015. Peel

has also initiated an update to its Official Plan to conform to the approved Source Protection Plans.

http://www.ctcswp.ca/

http://www.ourwatershed.ca/

http://www.protectingwater.ca/

34

As required under Source Water Protection Plans and Policies, Peel has commenced the process of

risk management planning for existing land uses that have been identified as significant threats to

our drinking water supply.

Peel also established an effective screening process, through which all land development

applications, planning or building permits within a vulnerable source protection area are assessed

for their potential risk to source water. In 2017, Peel issued 22 Notices in conformance with the

Act to proponents who have submitted development applications in source water protection

vulnerable areas.

Vulnerable areas have been delineated for Peel’s new municipal production wells and current

efforts include planning a threats verification exercise to ensure that all properties and land uses

within vulnerable zones are assessed for potential risk to Peel’s groundwater sources.

Peel’s Groundwater Monitoring Program

Peel has designed a comprehensive monitoring network within the WHPAs and Zones of Influence

(ZOI) for each of its municipal water supply wells to:

• Gain in depth knowledge of the groundwater sources supplying the municipal wells

• Monitor surface and groundwater levels and water quality to assess natural conditions

• Determine any potential effects on the ZOI from pumping of municipal supply wells

• Monitor surface and groundwater quality for early detection of potential contaminants

moving towards the aquifers, the source of water for the municipal supply wells.

The water quality monitoring regimen is reviewed from time to time address changes to the

monitoring network and to align it with new policies issued under source water protection plans.

Surface Water Supply Protection

The Collaborative Study to Protect Lake Ontario Drinking Water was a Peel-led initiative that

included 19 municipalities from Niagara Region to Prince Edward County along the Lake Ontario

35

shoreline. Through the Collaborative Project, intake protection zones and threats to the source of

drinking water (Lake Ontario) were identified using an event-based modelling approach. A three-

dimensional model was used to simulate possible contaminant pathways to and within Lake

Ontario and to assess potential concentrations at water treatment plant intakes.

Peel, Toronto and Durham as members of the Lake Ontario Collaborative Group (LOCG) under

the CTC Source Protection Plan are working on various initiatives to ensure measures are in place

to protect the Lake as a shared source of drinking water. Work plan includes spills scenario

modelling, real-time monitoring and future forecasting of spills impact assessments and assessing

spill prevention strategies for Lake Ontario intakes.

5.3 Private Well Abandonment Program The Region of Peel implemented a Private Well Abandonment Program for decommissioning of

old, unused private wells within Peel. This work is performed in accordance with the requirements

of the Ontario Regulation 903. The Program intends to gradually eliminate potential pathways of

groundwater contamination in areas where groundwater is a source for drinking water. The

Program is carried out on a first come, first serve basis, with each request being evaluated for

program eligibility prior to the commencement of any decommissioning work.

A total of 90 private wells throughout Peel were decommissioned under this program in 2017, with

a number of wells waitlisted for completion in early 2018. Participation in this program is

promoted though public events, newspaper ads, electronic newsletters, mobile road signs, as well

as outreach to local community centers and local real estate firms to help promote the program to

individuals living within or moving into rural areas of Peel. Also, internal outreach to groups

within Peel and education about the Private Well Abandonment Program help to maximize

opportunities to inform rural Peel residents about how they can take advantage of the program,

where applicable.

[email protected].

5.4 Watermain Renewal Program

Peel’s overall infrastructure is aging, requiring more investment in preventive and planned

maintenance. In response, Peel has established a comprehensive asset management program,

which includes watermain assessment and renewal. The program is an ongoing plan of upgrading

Peel’s watermain system to ensure long term integrity and sustainability. The program involves

repair or replacement of existing mains and water services to improve water flow, ensure good

quality water and upsize if required to meet future planning needs; all to provide a higher level

service to our consumers.

Peel determines priority of water main replacement based on the following factors:

• Watermain age

• Water quality trends and customer feedback

• Watermain size and material type

• Watermain breaks and leak history

• Hydraulic performance of watermain

• Planned municipal and city projects related to water, wastewater and roads assets

• Cost of replacement

• Operational demands

The majority of the watermain replacement projects are undertaken in partnership and coordination

with road re-construction and sanitary sewer renewal projects for improved cost effectiveness and

minimized public inconvenience. Using these criteria, Peel plans the watermain renewal program

in a financially responsible manner.

http://www.peelregion.ca/pw/water/water-trtmt/wellhead-abandon.htm


37

Every year, the watermain renewal program is allocated funding to replace a significant length of

watermain, with over $57 million being allocated to this project in 2017.

In 2017, 41.7 km of watermain was replaced in the South Peel Distribution System.

5.5 Community Lead Testing Program Established in 2007, Peel’s Community Lead Testing Program fulfills the legislative requirements

under the Ontario Regulation 170/03, Schedule 15.1. The scope of the program includes sampling

and testing of drinking water in Brampton, Mississauga and South Caledon for lead from private

residential and non-residential locations as well as municipal water hydrants.

Peel’s Community Lead Testing Program sampling locations are selected based on the following

criteria:

• Any homes or buildings built prior to 1960

• Any plumbing connected to or suspected to be connected to lead service pipes

• Any plumbing made out of or suspected of being made out of lead

The Community Lead Testing Program is conducted semi-annually between the dates of

December 15 to April 15 and June 15 to October 15 each year.

Every sampling period, Peel staff recruits volunteers of homes and businesses to participate in the

program. Sampling appointments are booked with volunteers over the phone. Upon completion

of sample analysis at a fully accredited and licensed laboratory, the test results reports are mailed

to their respective participants and assistance is provided in interpretation of the data.

Testing performed in 2017 revealed mostly non-detected or very low levels of lead in drinking

water at the tap. All plumbing samples tested met the standard for lead levels in drinking water of

10 parts per billion. Results for 2017 sampling are summarized in Appendix A of this report.

The Region of Peel welcomes the public to participate in our lead testing program, as results of

this program also aid in the asset management and water main renewal initiatives.

38

To check if your residence meets the criteria of our lead testing program, please contact us at 905-

791-7800 ext. 4685 or visit our website: http://www.peelregion.ca/pw/water/quality/lead-in-

water.htm

5.6 Watermain Flushing Program

Peel’s watermain flushing program is another element of the multi-barrier approach to ensuring

safe drinking water. The primary objective of the watermain flushing program is to maintain

adequate chlorine residuals in the water distribution system. Flushing is also conducted to improve

water aesthetics by removing any mineral deposits that may have settled on the bottom of the

mains over time. Under the Safe Drinking Water Act, 2002, Ontario Regulation 170/03 and

Procedure for Disinfection of Drinking Water in Ontario stipulate the acceptable chlorine residual

range. Certified Water Operators measure and record the chlorine residual at each flush. Flushing

is conducted at locations where a low water demand may occur, such as dead-ends and new

subdivisions, and at a greater frequency where demand is lower. Flushing is also conducted

following water system repairs and other situations where a check of chlorine residual is

warranted.

5.7 Hydrant Inspection Program

Peel’s hydrant inspection program fulfils a number of purposes. An annual

inspection is necessary to determine the sustained functionality of each fire

hydrant and hydrant branch valve to ensure they are operable for fire

suppression needs. Fire hydrant components that are in need of repair are

identified during the inspection. Deficiencies that affect the hydrant’s

operability are handled on a priority basis, due to their primary function of

fire protection.

All Region of Peel hydrants display hydrant flow identifiers. These flow identifiers are in

the shape of a Maltese cross. They are colour-coded based on the recommended colour

http://www.peelregion.ca/pw/water/quality/lead-in-water.htm


39

coding scheme by the National Fire Prevention Association and designed to let the fire department

know what the available flow is at the hydrant closest to the fire. The markers are reflective,

making them highly visible at night.

5.8 Drinking Water Sampling Station Program

In 2017, Peel continued with its program to install drinking water sampling stations

throughout the Region of Peel for the purpose of obtaining samples for regulated

water quality testing. The use of sampling stations has reduced the impact on

customers by decreasing the need to enter homes or business facilities where hours

of operation can limit access. In addition to unlimited access, Water Operations

also benefits by having added control over important sampling conditions such as

sample site cleanliness and security.

A number of sampling stations were installed in South Peel in 2017, and that

initiative continues, with sampling stations being installed during water

infrastructure expansion, watermain replacement, and other opportunities.

APPENDIX A – SUMMARY OF WATER TESTING RESULTS

Water Safety Indicators Information

Escherichia coli (E.coli)

Escherichia coli (E.coli) is a species of fecal coliform bacteria that can be detected using approved lab methods. E. coli is present in fecal matter and prevalent in sewage, but is readily inactivated by chlorine. It is a strong indicator of recent fecal pollution. If E. coli is detected in a sample of drinking water, immediate corrective action needs to be taken and confirmatory samples collected. Total Coliform

Total Coliforms are part of a family of bacteria called Enterics. Coliform bacteria grow under the same conditions as disease-causing bacteria, which makes them useful indicator organisms. Presence of coliform bacteria in a sample of drinking water signifies potential contamination. If coliforms are detected in a sample of drinking water, corrective action needs to be taken and confirmatory samples collected. Heterotrophic Plate Count

Heterotrophic plate count (HPC) results give an indication of the overall quality of the water immediately following treatment and in the distribution system. HPC is not an indicator of water safety but is used as an indicator of water integrity within the distribution system. Disinfection By-products

Disinfection of drinking water is essential to protect the public from waterborne infectious and parasitic diseases. Disinfection inactivates bacteria and other microorganisms in the water and protects the water pipes from any subsequent contamination during storage and distribution. The most commonly used drinking water disinfectant is chlorine, although Peel also uses ozone at one of its facilities. Chemical disinfectants can combine with naturally-occurring organic compounds in the water, potentially leading to the formation of disinfection by-products, including trihalomethanes (THMs), haloacetic acids (HAAs) and bromate.

APPENDIX B – FREQUENTLY ASKED QUESTIONS AND ANSWERS ON WATER QUALITY

Is my water safe to drink?

To protect public health, the Ministry of the Environment and Climate Change has established the

Ontario Drinking Water Quality Standards. These standards help ensure that water used by the

public is free from disease-causing organisms, harmful amounts of toxic chemicals and radioactive

materials.

Why do we use chlorine?

Chlorine is used to kill bacteria, viruses and other organisms that can cause illness. Ontario

Regulation 170/03 regulates the amount of chlorine that must be added. The regulation states that

we must maintain free chlorine residual at a minimum level 0.05 mg/L and should not exceed a

maximum level of 4.0 mg/L.

Is the water hard?

The water in the South Peel system is considered to be moderately hard. Hardness is typically

dissolved calcium and magnesium in the water measured as calcium carbonate. Upon heating, hard

water has a tendency to form scale deposits or a white film and can form excessive scum with

regular soaps. Conversely, soft water may result in accelerated corrosion of water pipes.

Should I buy a water softener?

The purchase of a water softener is based mostly on personal preference. Soap suds are formed

more readily with soft water, therefore less detergent is used. The use of a water softener also

reduces the formation of hardness scale in pipes and hot water tanks. Some consumers do not like

the feel of soft water. For example, after rinsing with soft water you may still feel a soap film on

your skin.

51

Why does my kettle get a white film inside?

When water is boiled, calcium and magnesium precipitate out of the water and deposit on the

element and inner surfaces of the kettle. This does not pose a health risk. The deposit can be

controlled by regular rinsing with vinegar or lemon juice.

Why does the water sometimes look “cloudy” or “milky”?

Tiny bubbles of air in the water cause the cloudiness. Those bubbles may also cause the water to

appear white or foamy, similar to the appearance of water in a rushing stream. This does not

indicate any problem and clears when the water is left to stand for a few minutes. This is an

aesthetic issue, not a health concern. If cloudy water persists, please notify the Region of Peel so

that the matter can be investigated.

Is fluoride added to my water?

Fluoride is added to the South Peel drinking water supply, which serves the cities of Brampton and

Mississauga and southern parts of Caledon, including the community of Bolton. The amount of

fluoride in the drinking water supply is regulated and is maintained at an optimal level to prevent

tooth decay.

Why does the water sometimes look “rusty”, yellow or Tea-like?

Excessive levels of iron in drinking water may impart a yellow to brownish colour, often seen on

laundered items, plumbing fixtures and in the water itself. Running your tap for a few minutes can

clear the colour. No health risks are associated with this discolouration. If you are experiencing

problems and your neighbours are not, the hot water tank or the pipes in your home are likely

causing the problem.

52

Does the Region of Peel knock on the door to test water or leave a bottle to fill?

Some of our water programs require testing on private premises, such as residential homes or

businesses. This would only be done by Peel with prior arrangements with the owner or tenant of

the premise. Based on the stringent provincial guidelines, drinking water samples must be

collected and handled by qualified persons and analysed at an accredited laboratory; therefore,

Peel staff would not leave a bottle at the door requesting a sample of water for testing, and will

always carry a Region of Peel identification card.

There are many responsible home water treatment businesses that offer products that live up to

their claims. Unfortunately, some companies and salespersons resort to grabbing the public’s

attention and misinforming them about the safety of the municipal drinking water supplies in an

effort to sell their products.

As of March 1, 2018, door to door sales of water heaters and treatment devices will be prohibited

by the Government of Ontario. To ensure that you are informed about the water quality in Peel

and less likely to become a target for a company trying to sell you costly and inappropriate water

treatment equipment, or if you have questions or concerns, please contact our Water Quality Team

at 905-791-7800 ext. 4685 or via e-mail to [email protected]. You can find

more information on our website at http://www.peelregion.ca/articles/door-to-door-agents.asp

Will you come to my house and take a sample?

If your water is supplied by the Region of Peel then you have no reason for concern about the

safety of your drinking water. The Region of Peel operates, maintains and monitors its municipal

drinking water systems in accordance with stringent provincial regulations and Peel’s drinking

water continually meets the established water quality standards.

Some of our water programs require testing on private premises, such as the Community Lead

Testing Program. This testing would only be done by a certified Region of Peel operator with prior


http://www.peelregion.ca/articles/door-to-door-agents.asp

53

arrangements made with the owner or tenant. More information about the Community Lead

Testing Program can be found in Section 5.5 of this report.

The Region of Peel collects a large number of samples from its drinking water systems to

demonstrate high quality water supply. The Region will only respond to a customer

enquiry/request by undertaking sampling at private taps if there is reason to believe that water

quality has been compromised that impacts both the tap water and municipal supply system.

Region staff occasionally sample at residential or commercial taps in conjunction with nearby

work in the private or municipal water system. Region staff will carry a Region of Peel

identification card.

Why is lead sometimes present in water?

Lead is a metal that can dissolve in water. Historically, lead compounds were used in plumbing

fittings and in solder to join pipes together in water distribution systems. If water stays in a piping

system that contains lead for long periods of time, lead may dissolve into the water.

How does lead affect my health?

Water Quality at Home Tips

Water Quality Concern Possible Cause Suggested Solutions

Chlorine Odour and Taste

• Chlorine combining with organics • Chlorination of new water mains • Effects of new plumbing • Change of residency as chlorine concentration

in drinking water varies from location to location

Chlorine is necessary to control disease-causing organisms. To minimize chlorine taste and odour in drinking water: • Fill a pitcher and let it stand in the refrigerator overnight • Blend the water for 5 minutes or pour between containers

about 10 times • Boil the water, let it cool, then refrigerate • Home plumbing may be flushed for a minute before water use

(especially in the mornings, after water has remained in pipes overnight)

Musty/Earthy Odour

• Algae that bloom in the lake in the summer produce a metabolite called ‘geosmin’, which causes musty/earthy odour

• The algae are harmless and although the water may not be aesthetically pleasing, it is safe

Rotten Egg/Septic

Odour

• Sink and floor drains • Faucet aerators/screens • Poorly maintained hot water tanks • Dead-end water mains or areas with low water

demand

• Refrain from flushing solids/organics down the drain; stagnant wastewater in the drain may generate foul odours and potentially plug the drain

• Clean faucet aerators and screens on frequent basis • Hot water tanks should be flushed periodically (every 2 to 3

years) to remove rust and scale

Milky/Cloudy Water

• Air trapped in water due to water main breaks, water temperature or pressure change, plumbing work, construction work in the area, water shut-offs

• Hot water tank temperature may be set too high

• Water is safe to drink • Run all cold water taps at once for a couple of minutes to flush

the lines and release the trapped air • Lower the hot water tank temperature if above 140°F(60°C)

Blue/Green Stains on Fixtures

• Copper in water due to copper plumbing • Run water for 30 seconds prior to consumption to reduce the

effects of local plumbing (metal concentration) • Keep fixtures dry and drip-free

Brown/Dirty Water

• Change in water flow due to: o Water main break o Hydrant use o Local Fire o Dead ends

• Poorly maintained hot water tank • No water use for a longer period of time; return

from vacation

• Open cold water faucets and flush water for 5 to 10 minutes, until clear

• Refrain from doing laundry to prevent clothes staining • Hot water tank should be flushed periodically (every 2 to 3

years) • Run cold and hot water separately to verify the cause; if hot

water is the cause - tank needs a flush • Open several faucets and flush the water standing in pipes that

may have dissolved pipe scale material

White Flakes/Particles

• Flakes are scale caused by hardness • Faulty or disintegrating hot water tank tubing

or lining

• Can be reduced by frequent cleaning of faucet aerators/screens and/or regular flushing of hot water tanks

• Contact the hot water tank company

Pink Staining on Fixtures

• Pink pigmented bacteria called Serratia marcescens

• Airborne bacteria; not originating from the water

• Scrub surfaces with a brush, disinfect with a strong bleach solution, allow disinfectant to penetrate for 10-20 minutes, rinse
