Our Vision
“To be recognized as the Industry Leader in Public Works” The Regional Municipality of Peel (Peel) takes pride in ensuring that its residents, businesses, and
visitors are provided with clean and safe drinking water.
The Region of Peel treats its source water to remove contaminants and regularly tests the water
quality to ensure its consumers are provided with high quality drinking water.
Thousands of water samples are collected throughout the year and tested for a variety of
microbiological, chemical, physical, and radiological parameters. The results of the tests
performed in 2015 confirm excellent quality of drinking water and have been consolidated in this
annual report.
If experiencing difficulty accessing or viewing the 2015 data results, please contact our Water
Quality Team at 905-791-7800 ext. 4685 or at [email protected].

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 much 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 2015, these
plants produced over 221 billion litres of water. Both plants are classified by the Ministry of the
Environment and Climate Change as Class IV treatment systems.
Distribution System / Storage Facilities The South Peel Distribution System is comprised of a Class IV Transmission and Pumping
system made up of water storage facilities, large diameter feedermains and pumping stations for
bulk water movement, and a Class II Distribution system 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, 3
elevated tanks, and 2 standpipes in the South Peel Drinking Water System.
The South Peel Distribution System consists of the following components: 4,286 km of
watermains, 44,754 mainline valves, 26,471 fire hydrants and 319,550 water services.
(2015- 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 2: Lakeview Water Treatment Plant
8
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 on page 9 for the Lakeview Water Treatment Plant Process Diagram.
The chemicals used at the Lakeview Water Treatment Plant during the reporting period were:
aluminum sulphate (alum) and Clar+Ion A502.5P – these are coagulants 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 sodium hypochlorite – used to clean the membrane filters sodium hydroxide – used to neutralize the spent membrane cleaning solution 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 excess 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.
Figure 3: Lorne Park Water Treatment Plant

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.
14
Conventional Filtration removes particles and bacteria that were not settled out in the previous
step and reduces the quantity of compounds that can cause unpleasant
tastes and odours. The water filters through layers of granular
activated carbon (GAC), sand and gravel. Water starts at the top of
the filter and moves down between the granules by gravity.
Note: at the Lakeview Water Treatment Plant, one of the sixteen filters was converted from GAC
to anthracite in 2013. In 2016, the remaining filters will be converted 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 September 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.
16
Filtered water is directed to the weir box. The weir box stores water and is also the
location where chlorine and fluoride are added.
Treated water from both the conventional treatment and the OBM treatment processes 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 state-of-the-art 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 special 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) compounds that cause unpleasant taste and odour. The
advanced oxidation process is used seasonally, when taste and odour problems are at their peak
due to lake conditions.
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 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.
17
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 using sodium hypochlorite and
aqua ammonia applied at the Airport Road Pumping Station.

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
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 terms and conditions of the drinking water regulations under the Safe
Drinking Water Act, 2002 for Peel’s drinking water systems and 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 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/) 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, the Region of Peel places an ad in the local newspapers to inform its consumers
about the availability of the Water Quality Reports.
19
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, 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 also collected for laboratory analysis for more than 150 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 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. This helps operators to gain knowledge of the latest industry practices,
20
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 adverse water quality event to
the Ministry of Health and the MOECC, and immediately initiates corrective action to address
and resolve the problem 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 2015 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, the Region of Peel 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, 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:

21
4. How well did we do?
4.1 Operation To protect the health of the public and to ensure consumers receive clean and safe water, the
Ministry of the Environment and Climate Change (MOECC) has established the Ontario Drinking
Water Quality Standards (ODWS) 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 reviewed from time to time based on new science and in keeping with the national drinking
water quality guidelines.
Ontario Regulation 169/03 was amended in 2015 and new water quality standards were adopted
for chlorate, chlorite, 2 methyl-4-chlorophenoxyacetic acid (MCPA) and haloaceticacids (HAAs),
as well as revision to existing standards to more stringent levels for arsenic, benzene, carbon
tetrachloride and vinyl chloride. The amendments also included removal of thirteen (13) organic
chemicals; pesticides that are no longer in commercial use, that have been de-listed from the
Canadian Drinking Water Quality Guidelines and which have not been detected in drinking water
samples in Ontario for approximately 10 years. The proposed amendments are being phased-in to
the sampling and testing regulatory requirements 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.
In 2015, 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
22
data review covered by the Ministry Inspector during each inspection. The South Peel drinking
water systems’ overall performance is excellent, ranking in the 90th percentile.
Figure 6: South Peel Systems MOECC Inspection Rating Graph
Note: The South Peel Distribution System became a separate waterworks in September 2013, prior to this the distribution system was considered a part of the Lakeview and Lorne Park drinking water systems. The 2015 inspection for Lakeview WTP was still underway at the time of this report.

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 valid DWWPs for all its 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 valid PTTWs for all its drinking water systems.
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 measures 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 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 has been successfully maintaining Full Scope - Entire
28
DWQMS accredited operating authority status since first awarded in August 2011. 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 maintains
Full-Scope – Entire DWQMS accredited operating authority since awarded in 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 SAI Global as the third-party
auditor for the purposes of providing 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 first-class outcome with full conformance to DWQMS and
auditor recommendation for offer of accreditation. A new certificate of accreditation, valid for
three years, was issued in March 2015.
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
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.
29
Summary of Approvals and Permits
Peel has satisfied all the approvals and permits 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. 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.

5.2 Source Water Protection
The Clean Water Act, 2006, 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 planned municipal sources of drinking water. The source protection process is driven by
locally-based Source Protection Committees that consist of appointed representatives from
municipal, industry, commerce and agricultural sectors and the public at large. The Region of
Peel falls under the jurisdiction of three Source Protection Authorities as follows:
• 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)
30
Region of Peel has participated in the planning phases of the source protection planning by
carrying out technical studies for assessment reports and policy development through Peel’s
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 threats identified, 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 was December 31st, 2015, and the SGBLS Source Protection Plan effective date
was July 1st, 2015.
Peel has an obligation to comply with the Source Protection Plans now that they are in effect. Peel
has prepared for the implementation of Part IV of the Clean Water Act, 2006 by appointing the
Risk Management Official and Risk Management Inspector in 2012 as well as through program
awareness and training sessions with relevant stakeholders. Peel has finalized the business
processes to review future development applications in vulnerable areas. 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, as all three pertinent
Source Protection Plans are now approved and in effect. Peel has also started to update its
Official Plan to conform to the approved Source Protection Plans and planning for risk
management of existing significant drinking water threats.
Peel’s Groundwater Monitoring Program
Peel has been monitoring water level and water quality within the Well Head Protection Areas
(WHPAs) of the active municipal water supply wells since 2004. In the spring of 2014, Peel
brought the Groundwater Monitoring Program in house and continued thorough monitoring as an
on-going program for wells supplying the communities of Alton, Caledon East, Caledon Village,
Cheltenham, Inglewood and Palgrave.
31
Peel has designed a comprehensive monitoring network within the WHPAs and Zones of
Influence (ZOI) of each municipal water supply well to:
• Improve the knowledge on 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 municipal supply wells
• Monitor surface and groundwater quality to detect potential contaminants moving towards
the aquifers supplying the municipal wells.
The water quality monitoring is reviewed from time to time address changes to the monitoring
network and to align 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 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.
Policies to address the identified drinking water threats have been developed and are included in
the Amended Source Water Protection Plan (SWPP) which was approved by the Minister of the
Environment and Climate Change on July 15th, 2015, and placed into effect on December 31st,
2015. The SWPP, along with an explanatory document and background information, can be
found at: http://www.ctcswp.ca/
32
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 well
decommissioning request being evaluated prior to the commencement of any decommissioning
work.
A total of 95 private wells throughout Peel were decommissioned under this program in 2015.
The increase in program participation has grown significantly since 2011. The increase is
attributed to Peel’s efforts toward public awareness through public events, newspaper ads, mobile
road signs, as well as outreach to local real estate firms to help promote the program to
individuals purchasing property in rural areas of Peel. Also, internal outreach to groups within
Peel and education about the Private Well Abandonment Program helped to maximize
opportunities to inform rural Peel residents about how they can take advantage of the program,
where applicable.

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. 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
• Watermain size and material type
• Watermain breaks and leak history
• Hydraulic performance of watermain
• Future municipal and city projects and road re-construction
• Cost of replacement
The majority of the watermain replacement projects are undertaken in partnership with road and
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.
Every year, the watermain renewal program is allocated funding to replace a significant length of
watermain, with over $62 million being allocated to this project to date.
In 2015, 36.6 km of watermain was replaced in the South Peel Distribution System.
34
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. This program requires the sampling and
testing of drinking water in Brampton, Mississauga and South Caledon for lead from private
residential and private 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 2015 revealed mostly non-detected or very low levels of lead in drinking
water at the tap. All residential and non-residential plumbing samples tested, with the exception
of two samples collected at the same location, met the standard for lead levels in drinking water
of 10 parts per billion. Results for 2015 sampling are summarized in Appendix A of this report.
Results of this program also aid in the asset management and water main renewal program.
The Region of Peel welcomes the public to participate in our lead testing program. 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
35
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. Under the Safe Drinking Water Act,
2002, Ontario Regulation 170/03 stipulates 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.
Flushing frequency is greater in areas where the water 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. The flushing part of the
inspection also serves to maintain chlorine residual at the hydrant. 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.
All Region of Peel hydrants are installed with hydrant flow identifiers. These flow
identifiers are in the shape of a Maltese cross. They are colour-coded based on the
recommended colour 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.
36
5.8 Drinking Water Sampling Station Program
In 2015, 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 2015, and that initiative continues,
with sampling stations being installed during water infrastructure expansion, watermain
replacement, and other opportunities.
37
APPENDIX A – SUMMARY OF WATER TESTING RESULTS Water Safety Indicators Information (E.coli, Total Coliform, HPC) Escherichia coli (E.coli)
Escherichia coli (E.coli) is 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 destroyed by
chlorine. It is a strong indicator of recent fecal pollution. If E. coli is detected in a sample of
drinking water, 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 allows us to use them as indicator organisms.
Presence of coliform bacteria in a sample of drinking water signifies potentially inadequate
treatment. 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. The use of chlorine may lead to the
formation of by-products, including trihalomethanes (THMs). THMs are formed when the
chlorine combines with naturally-occurring organic compounds in the water.

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 (ODWS). 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 you may still feel a soap film on your skin if you
used soft water.
48
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.
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
49
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.
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]
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 /Sour/Grassy/ Foul Odour
• Algae that bloom in the lake in the summer produce a metabolite called ‘geosmin’, which causes musty/earthy odour
• Dead-end water mains or areas with low water demand
• Poorly maintained hot water tanks • Faucet aerators/screens and sink drains
• The algae are harmless and although the water may not be aesthetically pleasing, it is safe.
• 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 • Refrain from flushing solids/organics down the drain;
stagnant wastewater in the drain may generate foul odours and potentially plug the drain
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 o Poorly maintained hot water tanks
or • Originated in 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 avoid staining fabrics • Hot water tank should be flushed periodically (every 2 to 3
years)
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 frequent 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
