Water Testing for Lead
Ontario Regulation 243/07
outlines the requirements that school boards and child care centres need to take with respect to water flushing and sampling for lead.
This legislation has been in effect since 2007 and has included an annual sampling schedule. To enhance the safety requirements around drinking water at schools and child care centres, the Ministry has amended the legislation to increase the number of samples taken at each site.
By January 2020, all drinking water fountains and faucets used for food preparation at all elementary schools and affiliated child care centres are required to be sampled; secondary schools are required to be completed by January 2022.
Ontario Drinking Water Standard
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). This is based on a national guideline from Health Canada.
If a drinking water test result is above the provincial standard for lead, the Durham Region Health Department will provide instruction to the DDSB for corrective action to ensure the safety of our students.
