Safe Drinking Water Act, 2002
The comment period for this proposal is now over.
Ontario has established a comprehensive safety net for drinking water with a source to tap focus. This multi-barrier approach includes a strong legislative and regulatory framework, health-based standards for drinking water, regular and reliable testing, swift strong action on adverse water quality incidents, mandatory licensing, operator certification and training requirements, a multi-faceted compliance improvement toolkit, and partnership, transparency and public engagement.
The Ministry of the Environment and Climate Change (the ministry) is seeking input on a proposal to amend the following regulations (and support documents) under the Safe Drinking Water Act, 2002:
- O. Reg. 169/03: Ontario Drinking Water Quality Standards and the Technical Support Document for Ontario Drinking Water Standards, Objectives and Guidelines
- O. Reg. 243/07: Schools, Private Schools and Day Nurseries
- O. Reg. 170/03: Drinking Water Systems
- O. Reg. 248/03: Drinking Water Testing Services
- O. Reg. 128/04: Certification of Drinking Water System Operators and Water Quality Analysts
With respect to the proposed changes to O. Reg. 169/03, the ministry is seeking stakeholder input on the “Technical Discussion Paper on Proposed Ontario Drinking Water Quality Standards and Aesthetic Objectives” (hereafter “Technical Discussion Paper”) that proposes regulatory amendments to Schedule 2 of O. Reg. 169/03.
The ministry is also seeking feedback on the proposed regulatory amendments intended to: further protect children from lead in drinking water; improve reporting requirements; streamline operator certification requirements; and correct and clarify regulatory language where ambiguous or out dated references exist.
The proposed changes fall into five main groups and are explained below.
1. O. Reg. 169/03 provides three Schedules listing the reportable maximum acceptable levels for Microbiological Standards (Schedule 1), Chemical Standards (Schedule 2), and the Radiological Standards (Schedule 3) prescribed as drinking water quality standards for the purposes of the Safe Drinking Water Act, 2002.
The Minister’s Advisory Council on Drinking Water Quality and Testing Standards (the Advisory Council) has provided advice to the ministry, recommending the following changes to Ontario Drinking Water Quality Standards, to take effect January 1, 2017:
- Adopt three new standards based on new federal guidelines:
- Ontario Drinking Water Quality Standard of 0.06 mg/L for Toluene based on new federal guidelines;
- Ontario Drinking Water Quality Standard of 0.14 mg/L for Ethylbenzene; and
- Ontario Drinking Water Quality Standard of 0.09 mg/L for Total Xylenes.
- Revise two existing standards:
- Revise Ontario Drinking Water Quality Standard of 0.01 mg/L to 0.05 mg/L for Selenium; and
- Revise Ontario Drinking Water Quality Standard of 0.03 mg/L to a more stringent value of 0.01 mg/L for Tetrachloroethylene.
- Remove the current Ontario Drinking Water Quality Standard of 10 mg/L for Nitrate + Nitrite as this parameter is redundant since individual standards of 10 mg/L for nitrate and 1 mg/L for nitrite are maintained.
The Advisory Council also made recommendations to adopt Health Canada's aesthetic objectives for the following substances, effective January 1, 2017:
- A new Aesthetic Objective of 0.015 mg/L is proposed for methyl t-butyl ether (MTBE); and
- Revise the Aesthetic Objectives for ethylbenzene and xylenes to 0.0016 mg/L, and 0.02 mg/L, respectively.
The Advisory Council recommended that the ministry update its “Technical Support Document for Ontario Drinking Water Standards, Objectives and Guidelines” with the information on the Drinking Water Quality Standards and the Aesthetic Objectives to reflect the outcome of this consultation.
The ministry has reviewed the recommendations of the Advisory Council and concluded that the proposed changes, based on new science, would be consistent with the purpose of Ontario’s Drinking Water Safety Net and would ensure Ontario’s drinking water quality standards are in line with the national drinking water quality guidelines.
As a result, it prepared the attached Technical Discussion Paper, which provides an overview of the process used by the ministry for the proposed changes for each contaminant and seeks stakeholder input for questions related to the proposed numerical value, benefits of adopting the proposed standard, and impacts to municipalities and drinking water system owners.
2. O. Reg. 243/07: Lead in drinking water is a significant health concern for the entire population, specifically for children age six and under, and negatively impacts infant brain and nervous system development. The Ontario Drinking Water Quality Standard for lead is 10 micrograms per litre (10 µg/L).
In 2007, as part of Ontario’s Lead Action Plan, new regulations were made to address potential sources of lead in drinking water including requirements for schools and day nurseries to:
- flush plumbing, either weekly or daily depending on risk factors;
- take a sample from at least one tap or fountain commonly used to provide water to children and test for lead annually or, under certain conditions, every three years;
- report lead levels above the Ontario Drinking Water Quality Standard (ODWQS) to the ministry as well as the local health unit and the Ministry of Education; and
- take corrective actions to address high levels of lead in drinking water.
To further protect children from lead in drinking water, updates to lead sampling, filter and flushing requirements are being proposed.
Currently, facilities are required to take samples for lead testing from at least one drinking water tap or fountain that is used to provide drinking water to children or for food preparation. There is no requirement to take samples from all the drinking water taps and fountains throughout the facility.
Recent studies have shown that lead levels in water from the plumbing system of a school or day nursery (now called child care centre) can vary substantially depending on the specific tap or fountain. The following regulatory amendments are being proposed to further protect children from lead in drinking water, and will help ensure that water samples from all drinking water taps and fountains – including those that have not been previously tested for lead – are tested:
a) For day nurseries/child care centres and primary schools (public and private), add the requirement to sample and test for lead at drinking water fountains and taps by the following timelines:
January 1, 2019: every drinking water fountain and every tap used in the preparation of food or drink, or to provide drinking water for consumption to children, and where a regulatory sample has not yet been taken;
After January 1, 2019: prioritize all other taps that can be accessed by children, for example, for hand washing, where a regulatory sample has not yet been taken – to be included as part of ongoing sampling of fountains and taps at the currently required frequencies (annually or once every 3 years).
b) For other schools (public and private), add the requirement to sample and test for lead at drinking water fountains and taps by the following timelines:
January 1, 2022: every drinking water fountain and every tap used in the preparation of food or drink, or to provide drinking water for consumption to children, and where a regulatory sample has not yet been taken;
After January 1, 2022: prioritize all other taps that can be accessed by children, for example, for hand washing, where a regulatory sample has not yet been taken – to be included as part of ongoing sampling of fountains and taps at the currently required frequencies (annually or once every 3 years).
c) Introduce mandatory corrective actions at any taps or fountains where a lead exceedance has been found from a flushed sample result at that location. Immediate action would need to be taken until the issue is resolved. These immediate corrective actions could include filtering, flushing, rendering the tap or fountain inaccessible to children by disconnecting or bagging, or any other measures as directed by the local Medical Officer of Health. The issue would only be considered resolved once a test result from a flushed sample from that location is below the Ontario Drinking Water Quality Standard for lead, or once a filter or other device certified to NSF/ANSI Standard 53, 58, 62 or equivalent for lead removal has been installed at that tap or fountain and the standing result from that location is below the Ontario Drinking Water Quality Standard for lead.
Use of filters
Recent studies have shown that filters or other devices certified to NSF/ANSI Standard 53, 58, 62, or equivalent for lead removal can be as good as or more effective at minimizing lead exposure than flushing.
This proposal would allow facilities to either continue with current flushing practices or to choose to move to using filters as a way of further reducing lead in drinking water taps and fountains.
If the facility chose to use filters, then they would be required to meet specific conditions to enhance protection of children, such as:
Standing sample results after the filter has been installed must be below 1 µg/L for that location.
Filter cartridges installed on taps and fountains will be required to be replaced according to manufacturers’ instructions (typically every three to six months), and records kept to document this maintenance. Records of filter maintenance may be required to be publicly accessible.
If the facility met the above conditions, then they may modify their flushing practices.
The proposed changes to flushing requirements will allow facilities to better protect children from lead in drinking water and stop flushing their plumbing in specific situations to enable better water conservation efforts.
a) Weekly or daily flushing requirements: The requirement to flush every fountain and tap throughout the facility for 10 seconds (either daily or weekly) would depend on the most recent test results taken from the specific locations:
Flushing would be required at any tap or fountain where at least one sample has been taken from that location, and where the most recent standing sample result from the location shows that the lead level is above 1 µg/L.
Records made for flushing activities would have to identify the locations where flushing is carried out.
b) Adjustment to the weekly 5 minute flushing requirement for each branch or run of pipe: Flushing would be required for at least one branch or run of pipe in the plumbing of each building where children have access. This would not affect facilities where daily flushing is required.
3. O. Reg. 170/03: Improve reporting requirements and clarify regulatory language while helping to maintain the protection of human health and the environment. The following amendments are being proposed:
a) Establish a screening value of 100 nanograms/Litre (ng/L) for pesticides that are not in Schedule 2 of O. Reg. 169/03 and currently do not have a drinking water standard in place, to initiate an Adverse Water Quality Incident (or AWQI).
The current regulation requires laboratories to report as an AWQI any pesticide not listed in O. Reg. 169/03 that is present in the drinking water, regardless of its concentration level.
Pesticides present at levels below 100 ng/L are generally not expected to cause health impacts.
Pesticides found at levels above 100 ng/L will continue to result in an AWQI, which is immediately reportable and results in guidance from the appropriate authorities.
- The proposed amendments would:
Confirm drinking water test results that indicate concentrations above 100 ng/L are to be treated as adverse results. Test results of 100 ng/L or below would no longer be required to be reported as an adverse result as they are not expected to pose a health concern.
Require all test results that indicate the presence of pesticides that do not have a standard in place to be provided to the ministry, even if their concentration levels are at or below the threshold of 100 ng/L. This new requirement will allow the ministry to better track the presence of all pesticides found in test results, and assess the need for the development of standards or other management strategy.
b) Remove obsolete provisions to grant full relief from treatment for secure groundwater systems related to viral presence in groundwater.
Existing provisions found in Schedule 4 and 5 of O. Reg. 170/03 are inconsistent with recent science indicating the presence of viruses in some groundwater sources.
The existing provisions have never been used and this proposed change reflects the ministry’s goal of modernizing our regulations by removing unnecessary requirements.
c) Remove the requirement for municipal and non-municipal drinking water system owners to submit lead testing summary reports to the ministry.
Licensed laboratories already upload lead test results to the ministry. They will continue to be required to send lead test results to system owners. Test results will be released as part of Ontario’s Open Data catalogue.
Content included in lead reports will be moved to annual reports, which are already required by the system.
d) Make general changes / corrections to existing language:
Update the list of control documents to be recognized by laboratories to include “municipal drinking water licence” where it was omitted.
Amend the word ‘sound’ to ‘signal’ when referring to the requirement for an alarm to sound when there is a problem at the system, since Operators can be alerted through other means, such as visual or vibrational indicators when SCADA or other alert systems are used.
Add wording to indicate that non-municipal residential systems that receive all their water from another regulated drinking water system and do not re-chlorinate water are not required to prepare Engineering Evaluation Reports, as there is no treatment equipment to evaluate. This would apply to non-municipal systems that are connected to other regulated drinking water systems.
Clarify the wording, as necessary, regarding the calculation of Running Annual Averages (RAAs) for situations where tests are only required once every three years. Currently calculations are done using the calendar quarter that immediately preceded the sampling and testing period but in some cases the last quarterly sample may have been taken over two years ago.
4. O. Reg. 248/03: Drinking Water Testing Services amendments. The following regulatory amendments are being proposed:
a) Shorten the timeframe for laboratories to upload data to the ministry from 28 to seven days. Shortening the upload time will provide the ministry with better opportunities to provide the public with more access to timely data about their drinking water.
b) Samples are to be retained by laboratories in accordance with conditions in their licences, which will make reference to good laboratory practices. This change will allow laboratories to discard samples when they are no longer viable, freeing up valuable space.
c) Require that results from all tests for which the laboratory is licensed to analyse be accessible to the ministry (including pesticides - see 3a above for more details).
5. O. Reg. 128/04: Update the requirements for Limited System Certification and Drinking Water Operator-in-Training (OIT) Certification.
5.1 O. Reg. 128/04: Update educational requirements to become a Limited System Operator so that they better align with the knowledge required to operate these systems, and with educational requirements in other Canadian jurisdictions. Even with the proposed change, Ontario would continue to have the most stringent operator certification and training requirements in Canada and would maintain the protection of human health and the environment. The following regulatory amendment is being proposed:
In Ontario, to obtain a Limited System certificate one is required to complete the Walkerton Clean Water Centre’s Operation of Small Drinking Water Systems course, pass the ministry’s certification examination and have a grade 12 diploma or equivalent.
The proposed amendment would replace the grade 12 requirement with grade 10, which is sufficient to be protective of the public and to meet the basic math and literacy skills that are required to operate this type of system.
Operators would still be required to complete the Operation of Small Drinking Water Systems course and pass the ministry’s certification examination. The course and exam will continue to help ensure that Operators have the knowledge they need to operate these systems.
Reducing the qualifications to Grade 10 supports smaller systems, including those in First Nations communities, by removing unnecessary barriers to operator certification.
The Grade 10 requirement is the jurisdictional norm for other Canadian jurisdictions. This amendment would be consistent with labour mobility provisions within the Agreement on Internal Trade.
5.2 Simplify the Operator-in-Training (OIT) certification process while maintaining stringent training requirements to ensure the safe operation of drinking water systems. OIT certificates are issued to persons who do not have the required one year experience to obtain a Class 1 certificate. An OIT is not permitted to make operational decisions within a drinking water system and is required to work under the supervision of an Operator-in-Charge or an Overall Responsible Operator.
Currently, to obtain an OIT certificate, one must have a grade 12 diploma or equivalent and must pass the OIT certification examination. Once certified, OITs must complete a two-week Entry Level Course within 16 months to have their certificate re-issued for 36 months. An OIT will typically upgrade their certificate to a Class 1 certificate once they gain the required one-year experience. Alternatively, if an OIT does not work full-time and has not completed the mandatory Entry Level Course, they can apply for a Temporary 12-month OIT certificate.
The following proposed amendments are intended to simplify the OIT certification process, and are consistent with most North American jurisdictions.
a) Eliminate the Temporary OIT Certificate.
Currently an OIT can apply for a temporary OIT certificate if they do not intend to work for more than four months in a seven month period as an OIT. Temporary OIT certificates can be renewed up to four times, without the Operator having to complete the mandatory Entry Level Course. This often results in multiple applications and confusion among applicants.
Having only one type of OIT certificate removes potential barriers for college students entering the profession, and supports the progression into higher classes of certificates.
Having only one type of OIT certificate simplifies the requirements for new Operators wishing to renew or upgrade their certificates to a higher class.
b) Extend the validity of an OIT Certificate to 36 months.
Currently, OIT certificates are valid for only 16 months. They can be renewed for 36 months from the date they are originally issued, provided they complete the mandatory Entry Level Course. With the proposed changes:
to renew OIT certificates, an OIT would still need to complete the mandatory Entry Level Course within the 36 month period; and
to be eligible to upgrade to a Class I certificate, an OIT would still be required to complete the mandatory Entry Level Course, meet operational experience requirements and write an exam within the 36 month period.
c) Allow OITs to operate Limited Systems under the supervision of an Operator-in-Charge or Overall Responsible Operator.
OITs are currently allowed to operate much larger and more complex systems than Limited Systems, under the supervision of an Operator-in-Charge or Overall Responsible Operator. Under the current regulation, OITs who work for operating authorities and operate these more complex systems are required to take a separate course and pass a separate examination to obtain a Limited System certificate in order to operate a Limited System.
Allowing OITs to operate Limited Systems would provide greater flexibility for owners of small private systems, rural municipalities and drinking water systems in First Nations communities.
This proposed amendment would not diminish the protection of drinking water provided by Limited Systems, as these systems would continue to be operated under the supervision of an Operator-in-Charge or Overall Responsible Operator who holds a Limited System certificate or a Class I or higher water treatment certificate.
With respect to the proposed changes to O. Reg. 169/03, the Minister’s Advisory Council on Drinking Water Quality and Testing Standards (the Advisory Council) has provided advice to the ministry, recommending that the government adopt three new Ontario Drinking Water Quality Standards based on new federal guidelines, revise two existing drinking water quality standards and remove one drinking water quality standard. The Advisory Council also made recommendations on adopting some substances as aesthetic objectives as the levels at which their presence makes the water unpalatable is lower than where health impacts are expected. The ministry has reviewed the recommendations of the Advisory Council and concluded that the proposed changes, based on new science, would be consistent with the purpose of Ontario’s Drinking Water Safety Net and would ensure Ontario’s drinking water quality standards are either in keeping with the national drinking water quality guidelines or are more stringent.
All other regulatory amendments are being proposed to further protect children from lead in drinking water; improve reporting and access to timely data; streamline operator certification requirements; and correct and clarify regulatory language where ambiguous or out dated references exist.
Please refer to the following postings on these topics:
- Technical Discussion Paper on Proposed Ontario Drinking Water Quality Standards and Aesthetic Objectives. Below are summaries for each of the substances from the Technical Discussion Paper on Proposed Ontario Drinking Water Quality Standards
- Selenium: Selenium is a naturally occurring element which is ubiquitous in the environment. It is generally present in various elemental forms. It is widely distributed in the Earth's crust and is found in trace quantities in most plant and animal tissues. Selenium is not directly mined, but rather is a by-product of the production of other metals. Selenium is used in the manufacture of chemicals, glass, paint, ceramics, electronic components, nutritional supplements, fertilizers, and other metallurgical applications.
- Nitrate and Nitrite: Nitrate and nitrite are widespread in the environment. They are naturally produced by the oxidation of nitrogen by microorganisms and, to a lesser extent, by lightning. The most common sources of these substances are human activities, including agricultural activities, wastewater treatment, and discharges from industrial processes and motor vehicles. Nitrate and nitrite can also be produced as a result of the nitrification process in source water or distribution systems. The concentration of free ammonia entering the distribution system can lead to nitrification and the potential increase of nitrate and nitrite in drinking water.
- Tetrachloroethylene: Tetrachloroethylene is primarily a synthetic chemical. In Canada, it is mostly used as a solvent in the dry cleaning industry and as an intermediate in chemical synthesis. In the rare instance it has been detected in drinking water sources, it is associated with spills or accidental releases from landfills. Tetrachloroethylene has not been produced in Canada since 1992 but continues to be imported.
- Toluene, Ethylbenzene, and Total Xylenes: Toluene, ethylbenzene and xylenes are primarily synthetic chemicals. These compounds are mainly found in petroleum hydrocarbons, such as gasoline and diesel fuel, or used as industrial solvents or as intermediates in styrene or benzene production. They can enter drinking water through leaching from contaminated sites or from industrial discharges of chemical manufacturing plants, or as a result of a spill during transportation or storage.
- Guidelines for Canadian Drinking Water Quality
This proposal was posted for a 59 day public review and comment period starting August 23, 2016. Comments were to be received by October 21, 2016.
All comments received during the comment period are being considered as part of the decision-making process by the Ministry.
Please Note: All comments and submissions received have become part of the public record.
Other Public Consultation Opportunities:
The proposed regulatory amendments take into consideration stakeholder feedback and suggestions from the Ontario Drinking Water Advisory Council (ODWAC), Public Health Units, Public Health Ontario, the Ministry of Health and Long-term Care, the Ministry of Education, the Canadian Council of Independent Laboratories, the Ontario Water Works Association and the Ontario Municipal Water Association.
The ministry is seeking comments or concerns on any or all of the proposed regulatory amendments from any interested stakeholders. The following questions highlight areas of interest to the ministry with respect to some of the proposed changes, but interested stakeholders need not limit comments/concerns exclusively to these questions:
Proposed changes to Ontario’s Drinking Water Quality Standards and the Technical Support Document for Ontario Drinking Water Standards, Objectives and Guidelines:
1. Do you agree with the adoption of the proposed numerical values for the Ontario Drinking Water Quality Standards for selenium and tetrachloroethylene and the new Aesthetic Objective for MTBE as described in this document?
2. With respect to toluene, ethylbenzene and xylenes, are you in favour of adopting Health Canada’s Aesthetic Objectives for ethylbenzene and xylenes with the revised values and adopting the Canadian Drinking Water Quality Guidelines (Maximum Acceptable Concentrations) for these three substances as Ontario Drinking Water Quality Standards?
3. What are the potential impacts on municipalities and other drinking water system owners to meet the proposed Ontario Drinking Water Quality Standards?
4. Are you supportive of the proposal to invoke an Adverse Water Quality Incident for pesticides without drinking water quality standards only if their individual levels are above 100 ng/L?
5. Do you agree with the January 1, 2017 time-frame for implementation of the Ontario Drinking Water Quality Standards described in this document and why?
Lead in schools and day nurseries/child care centres
6. Do you agree with the proposed requirement that, by January 1, 2019, day nurseries/child care centres and primary schools (public and private) must have tested for lead at all drinking water fountains, all taps used in the preparation of food or drink and all taps used to provide drinking water to children? Do you agree with the proposed requirement that, by January 1, 2022, other schools (public and private) must have tested for lead at all drinking water fountains, all taps used in the preparation of food or drink and all taps used to provide drinking water to children?
7. What are the impacts to day nurseries/child care centres and primary schools (public and private) to test all their drinking water fountains and taps used to prepare food or drink, or to provide drinking water to children by January 1, 2019, as proposed?
8. What are the impacts to other schools (public and private) to test all their drinking water fountains and taps used to prepare food or drink, or to provide drinking water to children by January 1, 2022, as proposed?
9. Do you agree with the proposed amendments to allow the use of filters or other devices certified to NSF/ANSI Standard 53, 58, 62 or equivalent for lead removal on taps and fountains in schools and day nurseries/child care centres?
10. Do you agree with keeping the current flushing requirements except in cases where the most recent standing sample results are below 1 µg/L?
11. The sampling window (May 1 to October 31) for lead would not change, since the warmer months of the year are when lead is more likely to be released from the plumbing system into the water. However, more samples would be required as a result of the proposed regulatory changes. Do you foresee any challenges with having to submit more samples for testing within the existing sampling window?
12. Do you agree that if a lead exceedance has been found in the flushed sample result from a tap or drinking water fountain, that the school or day nursery/child care centre would be required to immediately take corrective action (e.g. filtering, flushing, rendering the tap or fountain inaccessible to children) until the result from a flushed sample from that location is below the Ontario Drinking Water Quality Standard for Lead?
Reporting requirement for licensed laboratories
13. What are the impacts to decreasing the timeframe for labs to provide drinking water test results to the ministry from 28 to seven days?
14. Do you foresee any challenges for labs to make accessible to the ministry results from tests they are licensed to analyse, including pesticides?
Certification of Drinking Water System Operators
15. Do you agree that changing the requirement for Limited System operators to have a grade 10 versus a grade 12 education, while still requiring them to complete mandatory training and pass a ministry exam is sufficient to become certified?
16. Would eliminating the Temporary (12 month) Operator-in-Training Certificate and extending the validity of a regular OIT certificate from 16 months to three years, be problematic for new operators entering the profession? Do you agree that Operators-in-Training (who are certified to work in more complex drinking water systems than Limited systems) should be able to operate a Limited System under the supervision of an Operator-in-Charge or Overall Responsible Operator?
17. Are you assured that the proposed changes to operator certification requirements will maintain the protection of human health and the environment?
Regulatory Impact Statement:
The proposed updates to the Ontario Drinking Water Quality Standards are not expected to have a significant financial impact on owners of drinking water systems.
Changes to lead testing requirements for schools and day nurseries/child care centres are expected to increase testing costs for some systems. The changes will lead to greater assurance that children are not exposed to unsafe levels of lead in drinking water. Other amendments will provide schools and day nurseries/child care centres with additional tools to address lead.
Other regulatory amendments are likely to have no financial impact or may result in small cost savings by removing unnecessary regulatory requirements. For example, streamlining Operator-in-Training administrative requirements will result in a simpler career pathway for college students and other new Operators; the change to Limited System certificate requirements will reduce barriers to certification for small system Operators including some Operators of drinking water systems in First Nation communities.
