Message from the Chief Drinking Water Inspector

I am pleased to present the 2013-2014 annual drinking water report for Ontario.

The report contains information on how Ontario’s regulated drinking water systems and laboratories are performing, drinking water test results, and the ministry’s enforcement activities and programs.The results reinforce our commitment to providing high quality drinking water and illustrate continued performance improvement and overall systems ratings.

Our programs and legislative requirements form the foundation of Ontario’s safety net. Together, these comprehensive measures and regulations help ensure the safety of drinking water in Ontario. The consistency of drinking water test results for our regulated systems indicates they continue to provide high quality drinking water to the people of Ontario. In 2013-14:

  • 99.83 per cent of more than 527,000 drinking water test results from municipal residential drinking water systems met Ontario’s strict drinking water quality standards.

Likewise, high inspection ratings for these systems and laboratories that analyse our drinking water samples demonstrate that they continue to meet the Province’s regulatory requirements:

  • 99.4 per cent of inspections of municipal residential drinking water systems resulted in inspection ratings higher than 80 per cent, and 72 per cent scored 100 per cent — a four per cent improvement since 2012-13.

In this report, you will also find a message from Ontario’s Interim Chief Medical Officer of Health, Dr. David Mowat, and an update on the performance of the small drinking water systems regulated by the Ministry of Health and Long-Term Care.

Protecting Ontario’s Drinking Water

Source Water Protection

The source protection program, administered under the Clean Water Act, requires communities in Ontario to design source protection plans that identify potential risks to drinking water sources and develop strategies to reduce or eliminate these risks.

The 19 community-based source protection committees with representation from municipalities, First Nations, farmers, industry and the general public have collaborated to produce these watershed-based source protection plans. These plans are built on scientific research that will protect the sources of over 450 municipal drinking water systems across Ontario.

All 22 source protection plans have been submitted to the Minister of the Environment and Climate Change for approval and as of January 30, 2015, 13 of these plans have been approved:

  • Ausable Bayfield Maitland Valley Source Protection Plans
  • Cataraqui Source Protection Plan
  • Catfish Creek Source Protection Plan
  • Kettle Creek Source Protection Plan
  • Lakehead Source Protection Plan
  • Mattagami Source Protection Plan
  • Mississippi-Rideau Source Protection Plan
  • Niagara Peninsula Source Protection Plan
  • Quinte Region Source Protection Plan
  • Raisin-South Nation Source Protection Plan
  • South Georgian Bay Lake Simcoe Source Protection Plans
  • Sudbury Source Protection Plan
  • Trent Conservation Coalition Source Protection Plans

The remaining plans are on track for approval by the end of 2015.

Ontario’s Drinking Water Report Card

Drinking Water Quality Results

In 2013-14, 99.8 per cent of 638,190 drinking water tests from regulated drinking water systems met Ontario’s Drinking Water Quality Standards. For further details see appendix 1.

  • 99.83 per cent of the 527,278 drinking water tests from 6601 municipal residential drinking water systems met the standards
  • 99.46 per cent of 42,461 tests from 438 non-municipal year-round residential systems met the standards
  • 99.49 per cent of 68,451 tests from 1,376 systems serving designated facilities met the standards

The trend is consistent for all three system types showing that 		over 99% of drinking water test results since 2004-05 have met standards. For municipal residential drinking water systems, the percentage of drinking water test results meeting standards ranged from 99.74% in 2004-05 to 99.83% in 2013-14. For non-municipal year-round drinking water systems, the percentage of drinking water test results meeting standards ranged from 99.41% in 2004-05 to 99.46% in 2013-14. For systems serving designated facilities, the percentage of drinking water test results meeting standards ranged from 99.06% in 2004-05 to 99.49% in 2013-14.


1 There were slight variations in the methods used to tabulate the percentages year-over-year due to regulatory changes and different counting methods.

2 Lead results were not included as they were reported separately.

3 Lead distribution results were included and lead plumbing results were reported separately.

Drinking Water Quality Standards

Ontario’s drinking water must meet 158 strict health-based standards for microbiological, chemical and radiological parameters. These standards are listed in O. Reg. 169/03 of the Safe Drinking Water Act.

Drinking Water Quality Standards and Test Results

Microbiological Standards and Test Results

The presence of microbiological organisms such as total coliforms and Escherichia coli (E. coli) in drinking water could result in serious health problems. If total coliform or E. coli is positively confirmed, an adverse water quality incident is deemed to have occurred and the owner and/or operator of the drinking water system must take immediate corrective action.

The percentage of drinking water test results meeting microbiological standards over the past 10 years has remained stable and consistently high.

Table 1: Percentage of test results from municipal residential drinking water systems meeting Ontario’s Drinking Water Quality Standards, for E. coli by year

1 Regulatory requirements for testing vary by category and source of water and are identified in O. Reg. 170/03.

Chemical and Radiological Standards and Test Results

Ontario’s drinking water quality standards establish the maximum allowable concentration of chemicals that can be present in drinking water. Some adverse chemical test results may be due to naturally occurring deposits such as barium, fluoride and/or selenium.

Parts of the province also contain naturally occurring deposits of radiological parameters such as uranium. In these areas, regular drinking water testing is required to monitor the level of these parameters in water.

Adverse Water Quality Incidents and Corrective Actions

If a drinking water test result indicates a drinking water quality standard has not been met, or if an operational problem such as insufficient disinfection, high turbidity or equipment problems takes place in a drinking water facility, an adverse water quality incident (AWQI) is deemed to have occurred. It is important to note that the report of an AWQI does not necessarily mean the drinking water is unsafe; it indicates that an incident has occurred and that corrective action must be taken.

1 An AWQI may occur as a result of a single issue or multiple issues such as presence of microbiological or chemical parameters and/or operational issues.

Drinking Water Advisories

The local health unit may issue a drinking water advisory if there is concern that the water may not be safe for the public to drink. Some factors that could trigger an advisory include a broken watermain, low water pressure, microbiological parameters in the water, low disinfectant levels or equipment failure at a drinking water system.

In 2013-14, there were two municipal residential drinking water systems with long- term drinking water advisories:

  1. Richmond Community Drinking Water System, located near St. Thomas, had along-term drinking water advisory due to high nitrate levels in the source water. They have installed a treatment system to help lower the nitrate levels below the standard and are monitoring drinking water monthly. As the treatment process to remove the nitrate leads to high concentrations of sodium in drinking water, a second advisory has been issued to address the high concentrations of sodium.
  2. Lynden Drinking Water System, located near Hamilton, continues to have a long- term drinking water advisory due to lead in their drinking water. The advisory was issued to prevent potential long-term exposure to elevated concentrations of lead. According to the local medical officer of health, the current level of lead exposure does not represent an immediate health risk to residents. The affected residents continue to be offered on-tap filters that are certified to remove lead. Studies to identify the source of the lead and options to address the issue are ongoing.

Lead Action Plan

The ministry’s Lead Action Plan sets sampling, flushing and testing requirements to help minimize lead in drinking water. Regulated drinking water systems, schools and day nurseries must submit drinking water samples to laboratories to test for lead.

Lead Testing Results for Municipal Residential and Non-Municipal Year-Round Residential Systems

All municipal residential and non-municipal year-round residential drinking water systems are required to collect samples from homes (i.e. plumbing) and submit them to laboratories to test for lead.

In 2013-14, lead test results from these regulated systems indicate the vast majority of them continue to meet the provincial standard for lead in drinking water.

Municipal residential systems Lead in plumbing3 6,007 439 87 29
Non- municipal year-round residential systems Lead in plumbing3 1,339 2 123 2

1 Systems serving designated facilities are exempt from this requirement.

2 Regulatory requirements for testing vary by category and water source and are identified in O. Reg. 170/03.

3 Samples are taken after system is flushed.

Non-municipal year-round residential systems 98.82 98.95 99.85

1 Systems serving designated facilities are exempt from this requirement.

Lead Testing Results for Schools and Day Nurseries

Schools and day nurseries must also test their drinking water regularly for lead. They are also required to regularly flush their plumbing. Flushing reduces potential exposure to lead in drinking water because it prevents water from standing in the plumbing for too long, thereby reducing contact time with the pipes and plumbing. These facilities are required to sample their drinking water before and after they flush their plumbing.

Year after year, lead test results from schools and day nurseries indicate that flushing significantly reduces lead in drinking water.

1 Facilities that share the same plumbing system, known as co-located facilities, may submit a single set of samples. There are allowances for facilities to reduce sampling frequency to every 36 months from the required annual testing, based on a sufficient number of samples and satisfactory test results.

Corrosion Control for Municipal Residential Drinking Water Systems

Owners and/or operating authorities of municipal residential drinking water systems that serve more than 100 private residences must develop corrosion control plans if:

  • More than 10 per cent of the samples from homes (i.e. plumbing) confirm lead concentrations greater than the standard of 10 micrograms per litre in two out of three sampling rounds.
  • In those two rounds, at least two sample results exceed the standard.

In 2013-14, no additional owners/operators had to prepare corrosion control plans. The 20 municipalities that previously were required to prepare plans, continue to make significant progress to help address lead issues:

  • Eleven municipalities are implementing their plans.
  • Six are pursuing alternative lead control strategies, such as replacing lead service lines.

Of the remaining municipalities:

  • Arnprior completed modifications to its treatment process, undertook additional community lead sampling and will be submitting a corrosion control plan to the ministry.
  • Brantford is pursuing an alternative lead control strategy to replace lead service lines.
  • Sault Ste. Marie’s corrosion control plan is on hold while the city is evaluating additional actions and/or upgrades to their water treatment process and system.

For further details see Appendix 2.

Inspecting Drinking Water Systems and Issuing Orders

Municipal Residential Drinking Water Systems

Municipal residential drinking water systems are inspected annually by the ministry to determine whether they are meeting Ontario’s regulatory requirements.

Inspection Results

In 2013-14, ministry staff inspected 665 municipal residential drinking water systems. At least one out of every three inspections was unannounced. Of these, 481 systems (or 72 per cent) received a perfect score (100 per cent rating). That is four per cent higher than results from 2012-13.

Six hundred and sixty-one of the 665 (or 99.4 per cent) inspections resulted in inspection ratings of 80 per cent or higher.

For further details see Appendix 1.

Figure 2: Yearly comparison of municipal residential drinking water system inspection ratings1

A chart showing trends in inspection ratings for municipal residential drinking water systems over nine years. The inspection ratings are grouped into three categories. The number of inspections that yielded inspection ratings greater than 50% but less than or equal to 80% decreased from 18 in 2005-06 to four in 2013-14. The number of inspections that yielded inspection ratings greater than 80% but less than or equal to 99.99% decreased from 461 in 2005-06 to 180 in 2013-14. The number of inspections that yielded inspection ratings equal to a 100% increased from 233 in 2005-06 to 481 in 2013-14.


1 The decline in the total number of municipal residential drinking water systems is due to amalgamations of these systems.

2 Between 2005-06 and 2007-08 the ministry completed its planned annual inspection program of all municipal residential drinking water systems in Ontario generating its annual inspection rating for each system. During this period, for a number of reasons some systems were inspected twice, e.g., to capture both their treatment works and distribution systems or to ensure equipment had been properly decommissioned.

Orders and Order Resolutions

Ministry inspectors may issue orders to resolve and/or prevent non-compliance at a drinking water system. These contravention and/or preventative measures orders can be issued as the result of inspections, in response to incidents identified outside of an inspection or to prevent incidents from occurring.

In 2013-14, orders were issued to three municipal residential drinking water system owners and/or operators. All have complied with their order requirements:

  • Two contravention orders were issued to two systems after inspections for:
    • not ensuring that a licensed operator was present when work was being performed in a distribution system
    • not submitting a review of the operation of alarms
  • One preventative measures order was issued to one system to allow the operator to manually monitor the residual chlorine when computer system upgrades prevented continuous monitoring.

Individuals who are responsible for delivering safe drinking water to the people of Ontario are held legally accountable for their actions. As such, ministry inspectors may refer violations of Ontario’s environmental laws, such as the Safe Drinking Water Act, to the ministry’s Investigations and Enforcement Branch for further action.

Total 7 9 3

1 Non-inspection-related orders are issued as a result of an issue at a drinking water system that occurred outside of the context of a scheduled inspection.

For further details on these orders, please see appendix 3 and appendix 4.

Non-municipal Year-Round Residential Drinking Water Systems and Systems Serving Designated Facilities

The ministry uses a proactive, risk-based approach when determining which of these systems to inspect. Staff also take into consideration a system’s compliance history, how many AWQIs and why, as well as recommendations from local public health units.

Inspection Results and Orders

In 2013-14, ministry staff inspected 120 of the 4532 registered non-municipal year-round residential drinking water systems and issued four contravention and two preventative measures orders to six systems.

Additionally, 283 of 1,4963 registered systems serving designated facilities were inspected. Eight contravention orders were issued to eight systems.

Orders were issued for the following reasons:

  • Not operating a drinking water system with a certified operator
  • Not meeting minimum treatment requirements
  • Not sampling raw water for microbiological parameters according to legislation

Local Services Boards

There are seven local services boards in Ontario that operate drinking water systems in northern communities without municipal government structures. The ministry inspected all of them in 2013-14 and no orders were issued.

Schools and Day Nurseries

Registered schools and day nurseries, whether connected to a municipal drinking water system or not, are inspected by ministry staff to help reduce the risk of children being exposed to lead in drinking water. As with non-municipal year-round residential systems, the ministry uses a risk-based approach to determine which facilities should be inspected.

In 2013-14, the ministry conducted 376 inspections and 149 compliance audits of 10,999 registered schools and day nurseries.

The majority of Ontario schools and day nurseries regulated under O. Reg. 243/07 do not have excess lead in their drinking water

In 2013-14, no orders were issued to schools or day nurseries.

Inspecting Licensed and Eligible Laboratories

Ontario laboratories that test drinking water must be accredited by an accreditation body and licensed by the ministry. The ministry also uses laboratories that are located outside the province. For these laboratories to test Ontario’s drinking water, they too must be appropriately accredited and added to the ministry’s eligibility list.

All licensed and eligible laboratories are inspected by the ministry at least twice every year to determine whether they are meeting regulatory requirements.

All 52 of Ontario’s licensed and eligible laboratories that conduct drinking water tests were inspected twice in 2013-14.

The ministry has implemented an inspection rating methodology to measure the operational performance of licensed and eligible laboratories during their mandatory inspections. This methodology is similar to the inspection rating approach used for municipal residential drinking water systems.

During the reporting period, 42 per cent of licensed and eligible laboratories had inspection ratings of 100 per cent. Overall, all inspections had ratings of 90 per cent or more.

In 2013-14, no orders were issued to licensed and eligible laboratories.

2 Other inspections included laboratory pre-licensing or relocation inspections.

3 During 2011-12, of the two laboratories that received pre-licensing inspections, one did not receive any other inspection as it was granted its drinking water testing licence less than three months before the fiscal year ended.

4 During 2012-13, one laboratory that joined the licensing program in the second half of the fiscal year was not inspected; another laboratory voluntarily withdrew its licence during this time and was not inspected.

Compliance and Enforcement Regulation Requirements

The Compliance and Enforcement Regulation (O. Reg. 242/05) of the Safe Drinking Water Act requires the Ministry of the Environment and Climate Change to fulfill a number of specific activities such as taking mandatory actions and conducting inspections of municipal residential drinking water systems and laboratories that test Ontario’s drinking water.

The ministry met all its obligations under the Compliance and Enforcement Regulation in 2013-14.

Convictions

In 2013-14, there were 18 convictions involving 19 regulated drinking water systems resulting in fines that totaled $150,400.

3 Includes convictions against legal entities and individuals.

Operator Certification and Training

Ontario certifies and trains operators of regulated drinking water facilities. Once certified, drinking water operators in Ontario must be trained according to the type and class of facility they operate. The more complex a system is (the higher the class of system), the more training an operator must complete. If an operator works in more than one type of drinking water system, he or she may hold multiple certificates.

In 2013-14, 1,288 operator-in-training certificates were issued to 784 new operators. Of these, 24 were issued to 13 First Nations operators.

As of March 31, 2014, 6,321 operators held 8,744 certificates. One hundred and forty-six of them were employed as First Nations system operators across the province. These operators held a total of 219 drinking water operator certificates.

A chart showing trends in the number of certified drinking water operators in Ontario over eight years. In 2006-07, Ontario had 4,897 certified drinking water operators. Since then the number has increased by over 1,000 and there were 6,321 certified drinking water operators in Ontario as of 2013-14.

The Walkerton Clean Water Centre (the Centre) is one of the ministry’s key training partners, offering high quality hands-on operator training both on-site and throughout the province.

As of March 31, 2014, the Centre has trained more than 48,580 new and existing professionals since it opened in 2004.

Operator Certification — Disciplinary Actions

Operators play a key role in safeguarding Ontario’s drinking water, and ensuring the public is protected. Unethical behavior does not happen often, but when it does, the ministry takes it very seriously. Depending on the severity of the incident, the ministry will revoke or suspend operator certificates/licenses, or bar an operator from holding future certificates/licenses.

In 2013-14, the ministry revoked four certificates held by three operators and suspended the certificates of two others. Additionally, two operators received a written reprimand. Please see appendix 8 for further details.

Small Drinking Water Systems Program – Ministry of Health and Long Term Care

Message from the Chief Medical Officer of Health

As Ontario’s Interim Chief Medical Officer of Health, I am pleased to report that 2013-2014 saw another year of excellent program results, demonstrating that the Small Drinking Water Systems Program is working to protect the health of Ontarians.

The Small Drinking Water Systems Program is a unique and innovative program which, since 2008, has been overseen by the Ministry of Health and Long-Term Care and administered by local boards of health. It requires public health inspectors to conduct detailed inspections and risk assessments of all small drinking water systems in Ontario, and provide owner/operators with a tailored, site-specific plan to keep their drinking water safe. This customized approach reduces unnecessary burden on small system owner/operators without compromising strict provincial drinking water standards.

The success of the Small Drinking Water Systems Program has occurred through a shared commitment to excellence by the Ministry of the Environment and Climate Change, in partnership with the Ministry of Health and Long-Term Care, Ontario’s boards of health, Public Health Ontario Laboratories, and the Ministry of Natural Resources and Forestry. Thanks to a strong collaboration between these partners, Ontarians continue to benefit from a comprehensive safe drinking water program.

Small Drinking Water Systems Program Results

As of March 31, 2014, there were 12,942 small drinking water systems in Ontario. These systems are located across the province in semi-rural to remote communities and provide drinking water in restaurants, campgrounds, motels and bed and breakfasts, where there is not a municipal drinking water supply.

The Ministry of Health and Long-Term Care’s Small Drinking Water Systems Program is regulated under the Health Protection and Promotion Act and its regulations, and is administered by local boards of health (public health units) using a risk-based approach. Following a risk assessment of each system, the public health inspector provides the small drinking water system owner and/or operator with a legally binding directive customized to their system, which may include requirements for water sampling, water treatment options, operational checks and operator training.

A risk assessment begins with a physical (on-site) inspection of the water source, system equipment and components, and documentation relating to the system’s water testing and historical sampling results. Public health inspectors input the information into a web-based Risk Categorization Assessment Tool that evaluates all the factors that could influence the drinking water produced by a system and determines a level of risk (low, moderate or high) for the system.

As of March 31, 2014, 12,690 (98 per cent5) of the small drinking water systems operating in Ontario have had a risk assessment finalized and 252 are in progress.

Moderate 1,708 (15.88%) 1,938 (15.27%)
Low 7,258 (67.48%) 8,784 (69.22%)

Systems categorized as “high risk” are monitored through more frequent sampling and testing, and are required to be re-inspected every two years. While moderate and low risk systems are also monitored through routine sampling and re-inspections, drinking water is sampled and tested at a lower frequency and these systems are re-inspected every four years.

In 2013-14, 97.24 per cent of over 100,000 test results submitted by laboratories on behalf of small drinking water systems met the provincial standards.

Adverse Water Quality Incidents for Small Drinking Water Systems

As the primary contaminant of concern for small drinking water system water is bacteria, operators are required to test for microbiological indicator organisms such as total coliform and E. coli at a frequency outlined in their directive or as set out in regulations. Testing for other contaminants such as chemicals (e.g., nitrates) is only required where the risk assessment determines that other possible contaminants could potentially pose a risk. For example, a small drinking water system that is located near an agricultural or industrial setting may have a requirement in their directive to test for additional chemical parameters.

An adverse test result does not necessarily mean that users are at risk of becoming ill because immediate precautions are taken and drinking water advisories are issued where appropriate. If an adverse water quality incident (AWQI) is suspected (e.g., an observation of treatment malfunction) or detected by a test result, a response process is initiated which includes notification of users and the local medical officer of health. Further follow-up is immediately taken to determine if the water poses a risk to health if consumed or used and additional action is taken as required.

Regular sampling of drinking water systems is performed by operators who then submit the water samples to laboratories for testing. Test results are recorded in the Laboratory Result Management System. The Laboratory Result Management System is used for review of small drinking water systems’ sampling compliance, test results and AWQIs.

In the event of an adverse test result, the laboratory notifies both the owner and/ or operator of the small drinking water system and the local public health unit for immediate response to the incident. Details of AWQIs are also tracked in the Laboratory Result Management System.

During the current reporting period, a total of 2,801 adverse water test results, resulting in 1,340 AWQIs, were reported (from a total of 101,470 sample results). In addition, 177 AWQIs were identified through other means such as observation of treatment malfunction.

As an increasing number of owners and/or operators comply with sampling and monitoring requirements in accordance with their directive, the total number of AWQIs is also expected to rise slightly. For example, the number of AWQIs increased by three per cent from a total of 1,471 AWQIs in 2012-13 (including 155 identified through observation) to 1,517 in 2013-14.

Our adverse water quality incidents data demonstrates the importance of the Small Drinking Water Systems Program because these incidents are being identified and tracked, and immediate action is taken to help protect drinking water users.

Response to Adverse Water Quality Incidents for Small Drinking Water Systems

When an AWQI is detected through an observation or an adverse sample result, the owner and/or operator of the small drinking water system is required to notify the local medical officer of health and to follow up with any instruction that may be issued by a public health inspector or medical officer of health. The local public health unit will perform a risk analysis and take appropriate action to inform and protect the public.

Response to an AWQI may include issuing a drinking water advisory that will notify potential users whether the water is safe to use and drink or if it requires boiling to render it safe for use. The local public health unit may also provide the owners and/or operators of a drinking water system with instructions on necessary corrective action(s) to be taken on the affected drinking water system to mitigate the risk.

The Small Drinking Water Systems Program takes a comprehensive and proactive approach to help minimize the occurrence of AWQIs and safeguard water that comes from these systems. Local public health units provide information to owners and/or operators on:

  • How to identify possible contaminants at the source
  • How and when to test your water
  • Treatment options and maintenance of treatment equipment
  • When and how to notify users of the drinking water system
  • What actions need to be taken to mitigate a problem

Through the Small Drinking Water Systems Program, more operators know how to determine when their water may not be safe to drink and are working closely with public health units to take appropriate corrective actions to protect drinking water users.

The Small Drinking Water Systems Program reflects this government’s commitment to smarter regulatory practices without putting public safety at risk. Together we are working to ensure that drinking water quality standards established for the province are not compromised, while recognizing that these standards can be met in a way that also supports the needs of small system operators.

Glossary

Contravention Order
An order a provincial officer may issue under section 105 of the Safe Drinking Water Act if the provincial officer reasonably believes a person is contravening or has contravened a provision of the act or its regulations, an order issued under the act, or a condition in a certificate, permit, license or approval issued under the act. It may require the ordered party to comply with any directions set out in the order within the time specified.
Drinking Water Advisory
Notice issued by a local medical officer of health when a drinking water problem cannot be corrected simply by boiling the water or through disinfection. Under a drinking water advisory, consumers are advised to use another source of drinking water until further notice.
Drinking Water Systems Serving Designated Facilities
Drinking water systems that only serve designated facilities such as schools (elementary and public), universities, colleges, children and youth care facilities (including day nurseries), health care facilities, children’s camps and delivery agent care facilities (including certain hostels).
Escherichia coli (E. coli)
A species of bacteria naturally present in the intestines of humans and animals. If animal or human waste containing E. coli contaminates drinking water it may cause gastrointestinal disease in humans. Most types of E. coli are harmless, but some active strains produce harmful toxins and can cause severe illness and even death.
Local Services Boards
Provide services (including, in some cases, water services) to communities in areas of Northern Ontario without municipal structure. They are established pursuant to the Northern Services Boards Act. Drinking water systems run by local services boards are generally categorized as non-municipal year-round residential drinking water systems under O. Reg. 170/03.
Municipal Residential Drinking Water Systems
Drinking water systems (or part of a drinking water system) that are owned by and/or supply water to a municipality, that serve six or more private residences, and that meet other relevant criteria under the Safe Drinking Water Act and its regulations.
Non-Municipal Year-Round Residential Drinking Water Systems
Drinking water systems that are not municipal systems (and are not seasonal residential systems) that serves six or more private residences or a trailer park or campground with more than five service connections.
Preventative Measures Order
An order that a provincial officer may issue under section 106 of the Safe Drinking Water Act to a person who owns, manages or has control of a municipal drinking water system or a regulated non-municipal drinking water system, if the provincial officer considers it necessary for the purposes of the act. Such an order may be issued in the absence of a contravention, and is used to prevent possible future adverse effects.
Radiological Parameter
Refers to radionuclides which are an unstable form of a chemical element that decays and results in the emission of nuclear radiation.
Total Coliform
A group of waterborne bacteria consisting of three main groups with common characteristics that are used to indicate water quality. The presence of total coliform bacteria in water leaving a treatment plant or in any treated water immediately after treatment could indicate inadequate treatment and possible water contamination.
Trihalomethanes
A group of compounds that can form when the chlorine used to disinfect drinking water reacts with naturally occurring organic matter (e.g., decaying leaves and vegetation).
Water Quality
A term used to describe the chemical, physical and biological characteristics of water, usually with respect to its suitability for a particular purpose, such as drinking.

1 There were 665 municipal residential drinking water systems in 2013-14. Five systems that received their water from another municipal residential drinking water system had their samples represented within the samples collected and submitted by municipal residential drinking water systems that supplied water to them.

2 In 2013-14, some non-municipal year-round residential drinking water systems ceased to operate and/or data was not provided to the ministry.

3 The number of designated facilities that were registered in 2013-14 was less than those that submitted samples for the following reasons: some systems ceased to operate and/or data was not provided to the ministry, while some received drinking water for their cistern from municipal residential drinking water systems which carried out the required sampling on their behalf. Sampling was not required for those systems that posted notices advising people not to drink the water.

4 Chief Medical Officer of Health from September 2014 to March 2015.

5 The reported percentage of finalized risk assessments will fluctuate as new small drinking water systems are built/ come into use, or discontinue operation. The proportion of systems categorized as high, moderate or low risk may also fluctuate. While an initial assessment may result in a high risk categorization, a reassessment may reduce he level of risk if, for example, recommended improvements are taken to reduce the system’s risk. Similarly, a system may need to have another risk assessment, for example, if the water source and/or system’s integrity has been affected by adverse weather events and/or system modifications are made, to determine if the risk level has changed.
