Water Quality Testing

October 11, 2017

drinking fountain.jpgThe  Ontario Safe Water Drinking Act( Reg. 243/07) has, since 2007, required school boards to flush the cold water plumbing on a daily or weekly basis, maintain flushing logs, take annual water samples, and report drinking water test results to the Ministry of Environment and Climate Change (MOECC).  

On July 1st, 2017, the regulation was amended to require all school boards to take a water sample from every tap used for consumption and food preparation and from all fountains used by children under the age of 18.  Attached is the  MOECC fact sheet for all parents.   This information sheet describes the purpose of the regulation, why it's in place, changes and how our board complies with the regulation.  We have already begun the phased-in sampling of all required sample points, which will be completed by the January 1, 2022 deadline.

The MOECC also notes that taps which are not meant to provide water for consumption to children, are not required to be flushed or sampled from, and signage can be used to indicate this.  The current signage "DO NOT DRINK WATER" has served this purpose for several years.  This year, the signs will be replaced with "Handwashing Only" signs.  It is vital that you communicate the purpose of these signs to your children at taps used in classrooms, bathrooms,  utility and custodial sinks etc., which are not to be used for drinking or food preparation for children under the age of 18.

Thank you for your assistance with the implementation of the required regulation changes and your continued support of our water flushing and sampling program, to ensure that safe drinking water is provided in all Greater Essex County District School Board schools.

Safe Drinking Water in Child Care Centres and Schools

Since 2007, the Ontario government has been requiring child care centres and schools to flush the plumbing in their facilities and test their drinking water for lead. New amendments to Ontario Regulation 243/07 that take effect July 1, 2017 will now require lead testing within these facilities for all fixtures used to provide drinking water and/or prepare food or drink for children under 18.

Why does the Ontario government require child care centres and schools to test drinking water for lead?

Young children are more vulnerable to the effects of lead because they absorb ingested lead more easily than adults, which can interfere with the development of their nervous systems. In population studies, exposure to lead has been associated with effects on learning capacity, intellectual development and behavior.

How will the new rules coming into effect in July 2017 better protect children in child care centres and schools?

Ontario is proactively strengthening its regulation to protect children's health. Studies1 show that lead levels in drinking water from plumbing can vary substantially between individual taps or fountains. Only by testing each drinking water fixture can child care centres and schools be sure that they are not exposing children to lead through any of the plumbing within their facilities.

What is the drinking water quality standard for lead?

The Ontario drinking water quality standard for lead is 10 micrograms per litre. This standard is based on a national guideline set by Health Canada.

What happens if a child care centre or school finds it has lead in its drinking water above the standard for lead?

If a child care centre or school gets a drinking water test result that is above the standard for lead, the local Medical Officer of Health will assign corrective actions to the facility and it is the facility's responsibility to ensure those actions are carried out. The Ministry of the Environment and Climate Change will follow up with the facility operator and local Medical Officer of Health if necessary. These local processes have been in place since 2007 and are working well.

How can I find out the lead test results for my child's child care centre or school?

If you have questions about measures taken by your local child care centre or school to ensure the safety of drinking water, contact your local child care centre, school, or school board.

Why are child care centres and schools required to flush their plumbing?

Flushing has been shown to reduce lead levels in drinking water fixtures. By flushing plumbing and fixtures, water that may have come in contact with lead plumbing is replaced with fresh water. How often a facility has to flush their plumbing and fixtures depends on several factors including the age of the plumbing, previous lead test results or if a device that removes lead, such as a filter, has been installed on a fixture.

How are people exposed to lead?

Lead is a naturally occurring element. Lead has many industrial uses and has been found in water systems since the late 1800s. It is also present in soil, food and indoor dust. Over the past few decades, exposure to lead has significantly decreased due to restrictions in the use of lead in gasoline, paint and solder.

How does lead get into drinking water?

Ontario's surface and groundwater generally does not contain lead. If lead does occur naturally, the concentrations are typically extremely low and below the drinking water standard for lead. Where there are concentrations of lead in drinking water above the standard, the likely cause is from the lead pipes servicing the premises, lead solder used in the plumbing or fixtures containing high percentages of lead.

Lead pipe service connections have been used to deliver water from distribution pipes since the late 1800s. Older buildings (generally those built before the mid-1950s) are more likely to have lead connections. By 1990, the amount of lead in solder that could be used in drinking water plumbing was substantially reduced.

The amount of lead leaching into drinking water from these components depends largely on the chemical characteristics of the water. In certain circumstances, extended contact between standing water and the components can cause the lead to be released from the pipes. When the tap is turned on, water that has been standing in the pipes may have accumulated lead levels higher than Ontario's standard for lead.

How can I get the water in my home tested for lead?

If you suspect that you have lead service pipes or lead plumbing in your home, you may wish to have your tap water tested for lead. Some municipalities in Ontario have programs that help residents test their drinking water for lead. Contact your municipality for more information about your water service pipes and what is available in your community.

Alternatively, you can arrange your own drinking water lead test through a licensed laboratory.
