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 2013 confirm excellent quality of drinking water and have been consolidated in this annual report. If experiencing difficulty accessing or viewing the 2013 data results, please contact our Water Quality Team at 905-791-7800 ext. 4685 or at [email protected]. 3 1. General Drinking Water System Information 1.1 Where does the water come from? The South Peel Drinking Water System supplies a population of almost 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 2013, these plants produced over 222 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 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 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: 4,100 km of watermains, 42,298 mainline valves, 25,195 fire hydrants, and 311,202 water services. (2013- South Peel Water Distribution System) Some of the maintenance activities performed in the South Peel distribution system are: • watermain break repairs • hydrant maintenance and repairs 4 • valve maintenance and repairs • water service line installation/replacement/repairs • customer service calls (water quality/quantity, turn off/on, pressure testing, etc.) 1.2 Expenditure Information: Region of Peel staff determine capital spending priorities to eliminate unnecessary expenditures while maintaining its infrastructure.

How is Water Treated? 2.1 Lakeview Water Treatment Plant (Drinking Water Works Number 210000568) Figure 2: Lakeview Water Treatment Plant Located on the North shore of Lake Ontario, the Lakeview Water Treatment Plant 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 is operated as a conventional water treatment plant, as well as an advanced treatment plant consisting of ozone, biologically active carbon contactors (BACC) and membrane filtration. 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 below 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), alum/polymer blend coagulant, chlorine gas, citric acid, hydrofluosilicic acid, liquid oxygen, sodium bisulphate, sodium hydroxide, sodium hypochlorite, anionic polymer, and cationic polymer. Sodium hypochlorite is applied at the North Brampton Pumping Station, the Airport Road Pumping Station, and the Bolton South Booster Pumping Station for re-chlorination. Chlorine gas is applied at the Beckett Sproule Pumping Station for re-chlorination. Sodium hypochlorite and aqua ammonia are applied at the Airport Road Pumping Station to supply chloraminated water to York Region. The west side of Mississauga and Brampton are serviced primarily by the Lorne Park Water Treatment Plant. Several watermains link the two areas, allowing water to transfer from either east to west or west to east. Refer to Figure 5 for the South Peel Water Distribution Flow Chart.

Lorne Park has two treatment trains: 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). 10 Conventional/UV Treatment Conventional/UV treatment consists of the following steps: coagulation, flocculation, sedimentation, filtration, and disinfection by both ultraviolet (UV) light and chlorination. Refer to Section 2.3 for a detailed description. Membrane Filtration, Ultraviolet light, and Granular Activated Carbon Contactor (MUG) Treatment The MUG treatment process consists of modern, state-of-the-art, membrane filtration, UV light, and granular activated carbon contactor (GACC) treatment. Refer to Section 2.5 for a detailed description. To ensure an adequate supply of safe drinking water to an increasing population, construction of the MUG treatment train was commissioned in September 2012. The Lorne Park Water Treatment Plant has a total capacity of 500 million litres per day. Refer to Figure 4 below for the Lorne Park Water Treatment Process flow. The chemicals used at the Lorne Park Water Treatment Plant during the reporting period were: aluminum chlorohydrate (ACH), citric acid, hydrofluosilicic acid, hydrogen peroxide, polymer, sodium bisulphite, sodium hydroxide, sodium hypochlorite, and sulphuric acid. (http://www.peelregion.ca/pw/water/water-trtmt/lorne-park.htm) 11 Lake Ontario Screening Prevents fish, sticks and plants from entering and damaging equipment Conventional / UV MUG Coagulation/Flocculation/Sedimentation Membrane Filtration Removal of suspended and dissolved solids to improve filter performance Removal of small particles and microorganisms Filtration (GAC/Sand) Removal of small particles, organics, and microorganisms Ultraviolet (UV) Light Chlorination (Disinfection) Inactivation of bacteria/disease causing organisms GAC Contactors Ultraviolet (UV) Light Inactivates pathogens and controls taste and odour Inactivates pathogens and controls taste and odour Fluoridation Protects teeth from cavities Removal of residual hydrogen peroxide from the water Consumer Figure 4: Lorne Park Water Treatment Plant Process 12 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, it can be chlorinated. The chlorine kills bacteria and prevents zebra 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 and backwash pumps are located in several pump stations. 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 remaining particles and chlorine-resistant bacteria and reduces the quantity of compounds that can cause tastes and odours. The water travels 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 backwash treatment facility prior to being discharged into 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.

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 specially designed 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. 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. Filtered water is directed to the weir box. The weir box stores water and is also the location where chlorine and fluoride are added. 15 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 to reduce taste and odour in the water by a process called advanced oxidation. Advanced oxidation process 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. Advanced oxidation system would be used seasonally, when taste and odour problems are at their peak due to Lake and temperature 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. 16 2.6 Water Distribution System Mayfield West Elevated Tank Bolton Elevated Tanks Dixie Booster Station Snelgrove Elevated Tank West Brampton Pumping Station Reservoir Bolton Standpipes North Brampton Pumping Station & Reservoir East Brampton Pumping Station & Reservoir North Bolton Booster Station South Bolton Booster & PRV Tullamore Pumping Station & Reservoir York Region Maple Pumping Station & Reservoir Airport Pumping Station & Reservoir Meadowvale Pumping Station & Reservoir Battleford Booster Beckett-Sproule Pumping Station & Reservoir North Streetsville Elevated Tank Streetsville Pumping Station & Reservoir Herridge Pumping Station & Reservoir Lorne Park Water Treatment Plant Hanlan Pumping Station & Reservoir Silverthorn Pumping Station & Reservoir Lakeview Water Treatment Plant Figure 5: South Peel Water Distribution System Flow Chart 17 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 (MOE). 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 (MOE) 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 MOE for all drinking water tests performed. All laboratories used by Peel are accredited by the SCC, licensed by the MOE, 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 MOE-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, technologies and advanced processes and to effectively maintain system water quality and quantity. 19 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 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 2013 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 (MOE) inspection program to confirm compliance with provincial drinking water legislation. The MOE’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. MOE 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. 20 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 (MOE) 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 2013, 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 MOE performs annual inspections on all municipal drinking water systems. Based on the inspection findings, the MOE issues score cards. The score is based upon the questions posed by the Ministry Inspector during each inspection. The South Peel (Lakeview and Lorne Park) systems’ overall performance is excellent, and for the past three (3) inspection years has been in the 90th percentile.

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 (MOE) requires owners to have the following five (5) 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 has valid DWWPs for all its 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. The Region of Peel has a valid PTTW for each waterworks: Lakeview Water Treatment Plant; Lorne Park Water Treatment Plant; Palgrave-Caledon East; Caledon Village-Alton; Inglewood; and Cheltenham. 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 21 Element requirements of the MOE’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. 25 4. Accredited Operating Authority (third-party audit of the QMS) Municipal residential drinking water system owners must ensure that their operating authorities are accredited. Peel as the Operating Authority of the South Peel Distribution; Palgrave-Caledon East; Caledon Village-Alton; Inglewood; and Cheltenham Drinking Water Systems achieved Full Scope – Entire DWQMS Accreditation on August 26, 2011. Full Scope Accreditation recognizes that the Operating Authority has a QMS in place that conforms to the DWQMS as documented in the Operational Plan. Peel's QMS has been maintained and improved over the past five (5) years. In May 2012 the MOE designated two new accreditation bodies under the SDWA. In June 2012 the Region of Peel transferred its accreditation to SAI Global as the third-party auditor for the purposes of providing accreditation auditing services for a term that extends to August 26, 2014. 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 Water Division’s Financial Plan was prepared and approved by Council Resolution in June 2010 and submitted to the Ontario Ministry of Municipal Affairs and Housing (MMAH). The Financial Plan at a minimum is required to be updated; approved by Council Resolution; and submitted to the MMAH every five (5) years prior to an application for the renewal of the Municipal Drinking Water Licence. 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 MDWLs since late November 2009. Municipal Drinking Water Licences are valid for five (5) years. Peel will apply for Licence renewal for each municipal drinking water system in May 2014 to ensure continued authority to operate under the SDWA. 26 For more information on Peel’s Municipal Drinking Water Licensing Program please visit the following link: http://www.peelregion.ca/pw/water/quality/dwqms-peel.htm#2 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 Area; most of the Region of Peel’s groundwater and surface water intakes fall within this SPA (www.ctcswp.ca) • South Georgian Bay Lake Simcoe (SGBLS) Source Protection Area; only Palgrave Well no. 3 falls within this SPA (www.ourwatershed.ca) • Halton-Hamilton (H-H) Source Protection Area; 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. Source Protection Plans for H-H, CTC and SGBLS have been recently submitted to the Minister of the Environment for approval. All three plans have significant drinking water threat policies. There are monitoring and reporting policies for all significant threat policies. 27 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. One of the major steps taken by Peel is the appointment of the Risk Management Official and Risk Management Inspector in 2012. Peel is now working on developing new business processes to review future development applications in vulnerable areas and perform risk management of existing significant drinking water threats (SDWTs), 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. It is planned for these new business processes to be in place in the first quarter of 2014. Peel has also started to update its Official Plan to conform to the approved Source Protection Plans by 2015. Surface Water Supply Protection In partnership with the Source Protection Committees for Source Protection Regions, which use Lake Ontario as a source of drinking water, the intake protection zones and potential drinking water threats for the drinking water supplies have been identified. The Collaborative Study to Protect Lake Ontario Drinking Water is a Peel led initiative that includes 19 municipalities, from Niagara Region to Prince Edward County along the Lake Ontario shoreline. The Collaborative Project includes the following components: • Lake wide models to evaluate physical processes in Lake Ontario and enable the delineation of intake protection zones for municipal water treatment plants. • Watershed pollutant loading studies to evaluate pollutant loading to Lake Ontario. • Identification of potential drinking water threats (chemical or pathogen) to each municipal drinking water intake. Quantitative Microbial Risk Assessments (QMRAs) for the treatment processes at Lakeview and Lorne Park Water Treatment Plants were completed in 2012. The study concluded that both plants provide very high quality drinking water; the level of public health risk from water produced at 28 Lakeview and Lorne Park WTPs is at least ten times lower than the World Health Organization and Health Canada acceptable level of risk for drinking water.

This work is performed in accordance with the requirements of 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 83 private wells throughout the Region of Peel were decommissioned under this program in 2013. 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. For more information on Peel’s Private Well Abandonment Program, please visit the following link: http://www.peelregion.ca/pw/water/water-trtmt/wellhead-abandon.htm 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 29 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 2013, 27.2 km of watermain were replaced in the Region of Peel. 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 for lead from private residential and private non-residential locations as well as distribution hydrants. 30 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 2013 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 an exception of one, met the standard for lead levels in drinking water of 10 parts per billion. Results for 2013 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 905-7917800, 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 31 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. In 2013, Peel completed the installation of hydrant flow identifiers. These flow markers are in the shape of a Maltese cross. They are colour-coded 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. 32 5.8 Drinking Water Sampling Station Program In 2013, 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 2013, and that initiative continues, with sampling stations being included during water infrastructure expansion, watermain replacement, and other opportunities. 33 APPENDIX A SUMMARY OF WATER TESTING RESULTS Terms you need to know when reviewing the water testing results in this report Term Definition MAC Maximum Acceptable Concentration IMAC Interim Maximum Acceptable Concentration Aesthetic Objectives (AO) Operational Guidelines (OG) NTU AO are established for substances that affect the taste, smell and colour of water or interfere with water quality control practices.

This is a measure of concentration of a substance in water, also called parts per million (ppm). less than 34 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. 35 Summary of Microbiological Testing for South Peel (Lakeview, Lorne Park, and Distribution) Drinking Water System for the Reporting Period of January 1 to December 31, 2013 Sample Type Number of Samples Range of E. coli Results (CFU/100mL) (Min - Max) Range of Total Coliform Results (CFU/100mL) (Min - Max) Number of HPC Samples Range of HPC Results (CFU/mL) (Min - Max) Raw 107 0 - 24 0 - >2000 107 0 - 3100 Treated 444 0 0 150 0-2 Distribution 5554 0 - NDOGT 0 - NDOGT 5554 0 - 100 Ontario Drinking Water Quality Standards: E. coli = 0 CFU/100mL; Total Coliform = 0 CFU/100mL NDOGT = No Data; Overgrown with Target Organisms Summary of Testing and Sampling Carried out in Accordance with the Requirement of an Approval, Order, Permit, Licence or Other Legal Instrument Summary of Results for Total Suspended Solids (TSS) on Process Waste Water at the Lakeview and Lorne Park Water Treatment Plants, As Required by the Municipal Drinking Water Licence, Tested at an Accredited, Licensed Laboratory for the Reporting Period of January 1 to December 31, 2013 TSS Sampling Location Units Standard or Requirement Range of Results (Min - Max) Average Lakeview WTP Wastewater Supernatant mg/L ≤15 as an annual average <1 – 80 16.78* Lakeview WTP Membrane Backpulse mg/L ≤15 as an annual average <1 - 82 10.60 Lorne Park WTP Wastewater Supernatant mg/L ≤15 as an annual average 3 - 63 8.97 * Annual average TSS exceedence reported to the Ministry of the Environment, as required 36 Summary of Results for Inorganic Parameters per Schedule 23 of O.Reg. 170/03 Tested at an Accredited, Licensed Laboratory on Annual Grab Samples of Treated Water Collected During the Reporting Period Jan 1 to Dec 31, 2013 Test Parameter Units MAC Lakeview Result Lorne Park Result Antimony (Sb) µg/L 6 <0.50 <0.50 Arsenic (As) µg/L 25 <1.0 <1.0 Barium (Ba) mg/L 1.0 0.023 0.024 Common in sedimentary rocks Boron (B) mg/L 5.0 0.022 - 0.025 0.023 Normally found in very small levels in drinking water Cadmium (Cd) mg/L 0.005 <0.00010 <0.00010 Rare element unlikely to be present as natural contaminant in drinking water Chromium (Cr) mg/L 0.05 <0.005 <0.005 Trivalent chromium naturally occurs and is not considered toxic Mercury (Hg) mg/L 0.001 <0.00010 <0.00010 Sources in drinking water can be air pollution, waste incineration and metal refining operations Selenium (Se) mg/L 0.01 <0.002 <0.002 Uranium (U) µg/L 20 0.32 - 0.37 0.34 Parameter Information Naturally occurring metalloid rarely detected in Ontario Drinking Water Sometimes found in high concentrations in ground water in hard rock areas through the natural dissolution of arsenic-containing minerals Naturally occurs in water at trace levels Normally occurring in granite and other mineral deposits, leaches into water 37 Summary of Community Lead Testing Program Results per Schedule 15.1 of O.

To protect public health, the Ministry of the Environment 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. 45 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. 46 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?

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) • • • • • • • • • • • • 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 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) Run water for 30 seconds prior to consumption to reduce the effects of local plumbing (metal concentration) Keep fixtures dry and drip-free 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) • 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 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 48 Report Accessibility The 2013 Annual Reports can be viewed by the public on-line at: http://www.peelregion.ca/pw/water/quality/reports or picked up at the Region of Peel office located at 10 Peel Centre Drive, Brampton.
