Water Testing for Lead

WRDSB follows Ministry of Environment and Climate Change (MOECC) legislation regarding drinking water. This includes an annual lead testing cycle, and working with Region of Waterloo Public Health officials to do any corrective actions they required to do.

To be more transparent about these tests, their results and the corrective actions we take, it’s important to understand recent amendments to Ontario Regulation 243/07.

To enhance the safety requirements around drinking water at schools and child care centres, the MOECC has increased the number of tests taken at each site and is making the results of these tests available to the public.

By January 2020, WRDSB is testing all drinking fountains, bottle fillers and taps used for food preparation (drinking water fixtures) at elementary schools and affiliated child care centres. We will complete testing at senior elementary and secondary schools by January 2022.

Ontario Drinking Water Standards

According to Health Canada’s guideline, the Ontario drinking water quality standard for lead is 10 micrograms per litre (also written as 10 µg/L or as 0.010 milligrams per litre). When levels of lead that are higher than provincial standards are detected, we take immediate action to protect our students, following directions from MOECC guidelines, in consultation with the Region of Waterloo Public Health and Emergency Services.

Questions about testing water for lead

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 behaviour.

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. Studies 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.

How can the Ministry the Environment and Climate Change (MOECC) guarantee that students aren’t drinking from fountains that have lead issues (is the school responsible)?

Ontario has a strong framework to address and follow up on lead exceedances. This framework includes strict monitoring and inspection requirements and engagement with the Local Medical Officer of Health and owners/operators of the facility showing the exceedance to resolve issues in a timely manner. Throughout the year and during inspections, MOECC staff review all adverse test results to ensure incidents have been appropriately addressed and to assess compliance with any corrective actions issued by the local Medical Officer of Health.

Facilities must take immediate corrective action at any tap or drinking fountain where a test result shows a lead exceedance. These actions could include increased flushing, replacing the fixture, installing a filter or other device that is certified for lead reduction, rendering the tap or fountain inaccessible to children by disconnecting or bagging, or any other measures as directed by the local Medical Officer or Health, until the issue is resolved.

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 many times can a school test their water to meet the standard?

Child care centres and schools with a primary division (Grade 3 and under) must sample at least one-third of their drinking water fixtures in each of 2017, 2018 and 2019, with all drinking water fixtures sampled by January 1, 2020. Other facilities (middle and high schools) must sample all their drinking water fixtures by January 1, 2022. There is no maximum limit to the number of times a facility can sample their water for lead, in just over the next two years, every tap for primary schools and child care centres will be tested.

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

In an effort to be transparent, WRDSB has listed the impacted schools from 2017 forward. If you have questions about any measures taken by your local child care centre or school to ensure the lead level safety of drinking water, contact your local child care centre, school or school board.

What’s the difference between standing and flushing? Why does MOECC require both?

A standing sample is a sample of the first water that comes out of the tap that could have been “standing” in the pipe and not flowing whereas a “flushed sample” is a sample of water that has had a chance to flow before taking water from the tap or fountain.

While lead is generally not found in water from municipal drinking water plants, it may be present in the distribution piping with the streets and in certain facilities (schools) with older pipes, solder and fixtures, especially buildings built prior to 1990. Flushing of plumbing has been proven to decrease the amount of lead in drinking water in these cases. Facilities are required to take samples of the drinking water from the drinking fountains and taps before and after they flush the plumbing. A comparison of the flushed sample results versus the standing sample results consistently shows that flushing significantly reduces lead in drinking water.

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. For more information please visit Ontario Ministry of the Environment and Climate Change – Drinking Water Information or phone the Public Information Centre at 1-800-565-4923.
