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 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.
A number of tests were performed on thousands of water samples collected throughout the year,
including testing for microbiological, inorganic and organic parameters. The results of the tests
performed in 2014 confirm excellent quality of drinking water and have been consolidated in this
annual report.
If experiencing difficulty accessing or viewing the 2014 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. 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
2014, these plants produced over 217 billion litres of water. A portion of water produced is also
pumped into York Region. 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, 4
elevated tanks, and 2 standpipes in the South Peel Drinking Water System.
The South Peel Distribution System consists of the following components: 4,223 km of
watermains, 45,179 mainline valves, 25,872 fire hydrants and 317,549 water services.
(2014- South Peel Water Distribution System)
Some of the maintenance activities performed in the South Peel distribution system include:
• watermain break repairs

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 (BACC) 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 per day of treated drinking water.
Figure 2: Lakeview Water Treatment Plant
7
Conventional Treatment
Conventional treatment consists of the following steps: coagulation, flocculation, sedimentation,
filtration, and 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), chlorine gas, citric acid, hydrofluosilicic acid, liquid oxygen, sodium
bisulphite, sodium hydroxide, sodium hypochlorite, sulphuric acid, anionic polymer, and cationic
polymer.
The drinking water in the South Peel Distribution System is re-chlorinated using sodium
hypochlorite at the North Brampton Pumping Station, the Airport Road Pumping Station, and the
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.
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 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
per day of treated drinking water.

2.3 Conventional Water Treatment Process Description 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)
in 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
or the water is slowed down in large tanks to allow particles to settle to the
bottom. The settled solids are removed and transferred to the wastewater
treatment facility.
13
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.
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 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, commercial and industrial
premises. Refer to Figure 5 for the South Peel Water Distribution Flow Chart.

2.4 Ozone, Biologically Active Carbon, and Membrane (OBM) Water Treatment Process
Description
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 BAC contactors 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, just commissioned
in September 2014, and 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.
15
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, Granular Activated Carbon and Membrane (MUG)
Water Treatment Process Description
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.

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 the operation,
level of treatment, sampling and testing, 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 regarding 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. 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/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, the Region of Peel places an ad in the local newspapers to inform its consumers
about the availability of the Water Quality Reports.
18
3.2 Sampling and Testing In compliance with the drinking water legislation, drinking water systems are required to monitor
their water quality to ensure it meets provincial standards.
Peel regularly samples and tests raw, treated and distribution system water for a number of
microbiological, chemical and radiological parameters. Peel has always had an extensive water
sampling and monitoring program to better understand the quality of source water, ensure
effective 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,
19
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 Ministry of the Environment and Climate Change, 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 2014 events 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 Ministry of the
Environment and Climate Change (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 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.

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). These standards are set to ensure the water is free of disease-
causing organisms and hazardous and radioactive chemicals. In 2014, 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 is based upon the questions
posed by the Ministry Inspector during each inspection. The South Peel systems’ overall
performance is excellent, ranking in the 90th percentile.

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. In order to be issued a Licence, the Ministry of the Environment and Climate
Change (MOECC) requires owners to have the following five prerequisites:
1. 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.
2. 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.
3. 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.
4. 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, as the operating authority of
the South Peel Distribution, Palgrave-Caledon East; Caledon Village-Alton, Inglewood, and
26
Cheltenham Drinking Water Systems has been successfully maintaining Full Scope - Entire
DWQMS accredited operating authority status since first awarded in August 2011. Ontario Clean
Water Agency (OCWA), as the operating authority for the Lakeview Water Treatment Plant,
Lorne Park Water Treatment Plant, and South Peel Water Transmission and Pumping System has
been successfully maintaining Full Scope – Entire DWQMS accredited operating authority status
since 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. Continuance of
accreditation is based on a three-year review cycle. This is accomplished through annual
surveillance offsite audits in years one and two and an on-site verification audit for DWQMS
reaccreditation in year three. Peel’s on-site verification audit for reaccreditation is scheduled for
early 2015.
5. 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.
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 municipal drinking water systems under the new DWWPs and
27
MDWLs since late November 2009. Municipal drinking water licences are valid for five years.
Peel submitted applications for licence renewal in May 2014 and new licences were issued for
each municipal drinking water system in November 2014 to ensure continued authority to operate
under the SDWA, 2002.

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 the Region of Peel’s groundwater and surface water intakes fall within this SPA
(http://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 the Region’s groundwater
systems or surface water intakes lies within this SPA (www.protectingwater.ca)
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 Region of
Peel’s representation on the Source Protection Committees and working groups whose work led
to the development of Proposed Source Protection Plans.
28
The amended Proposed Source Protection Plans and accompanying amended Proposed
Explanatory Document for the CTC and SGBLS SPAs have been submitted for approval by the
Minister of the Environment and Climate Change in 2014. H-H plans to submit their amended
Source Protection Plan and accompanying amended Proposed Explanatory Document to the
Minister of the Environment and Climate Change for approval. There are monitoring and
reporting policies in the Source Protection Plans for all significant threats identified in the
updated Assessment Reports.
The Region of Peel has an obligation to comply with the Source Protection Plans once approved.
Peel is currently preparing for the implementation of Part IV of the Clean Water Act, 2006. One
of the major steps taken by Peel is the appointment of the Risk Management Official and Risk
Management Inspector in 2012. Peel is currently finalizing business processes to review future
development applications in vulnerable areas and perform risk management of existing significant
drinking water threats, as identified through a threats verification exercise led by Peel in 2012 and
2013. A comprehensive database management, filing and records keeping system is being
developed using internal resources. These business processes are expected to be fully
implemented once the Source Protection Plans are approved. Peel has also started to update its
Official Plan to conform to the approved Source 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
29
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 submitted for approval to the
Minister of the Environment and Climate Change in December 2014. The SWPP along with an
explanatory document and background information can be found at: http://www.ctcswp.ca/
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 93 private wells throughout Peel were decommissioned under this program in 2014.
The increase in program participation has grown significantly since 2011 with an 11 percent
increase in participation from 2013 to 2014. 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.

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 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.
In 2014, 52.9 km of watermain were 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. This program requires the sampling and
31
testing of drinking water 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 2014 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, met the standard for lead levels in drinking water of 10 parts per billion. Results for 2014
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 qualifies for a free lead test of your drinking water, 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 The Region of 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
The Region of Peel 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.
33
5.8 Drinking Water Sampling Station Program
In 2014, 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 2014, and that initiative continues,
with sampling stations being included during water infrastructure expansion, watermain
replacement, and other opportunities.

Water Safety Indicators Information (E.coli, Total Coliform, HPC) Escherichia coli (E.coli) Escherichia coli (E.coli) is a fecal coliform 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 Coliform bacteria 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 overall water quality in drinking
water systems. HPC results are used as a tool for monitoring 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 in the water and protects the water pipes from
any subsequent contamination during storage or 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, hazardous 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? 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. The water in the South Peel system is considered to be moderately hard.
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.
46
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 Town of Bolton. The amount of
fluoride in the drinking water supply is regulated and is maintained at an optimal level that
prevents tooth decay.
Why does the water sometimes look “rusty”, yellow or Tea-like? Yellow water is a common occurrence. 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.
47
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.
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? For more information contact Peel Health at http://www.peelregion.ca/health/ To view our Lead Pamphlet, please visit: https://www.peelregion.ca/health/environNew/athome/lead.pdf

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
