\u2018F\u2019 for Effort: Ontario is falling behind on getting lead out of school drinking water<\/a>, analyzed provincial data to reveal its ranking of the top 10 schools in the province with lead tests over 5 and 10 ppb in 2024-2025. They also revealed the school boards with the highest number of schools with lead-in-drinking-water levels above those levels.<\/p>\nIndividual school rankings<\/p>\n
Beaver River Public School in Beaverton, Ont., topped the list with 15 tests exceeding 10 ppb during that time frame and 33 with more than 5 ppb.<\/p>\n
Mississauga\u2019s St. Francis of Assisi Separate School came in sixth place with seven tests at more than 10 ppb and nine with more than 5 ppb.<\/p>\n
Hamilton\u2019s Sherwood Secondary School in Hamilton placed eighth with six tests exceeding 10 ppb and 11 exceeding 5 ppb.<\/p>\n
St. Kevin Separate School in Brampton rounded out the list, coming in 10th place with five tests with more than 10 ppb and 10 with more than 5 ppb.<\/p>\n

The Canadian Environmental Law Association noted that the true scope of this problem is likely being underreported.<\/p>\n
\u201cMany schools with known lead infrastructure have been exempt from regular testing and are not represented in the data. This is because Ontario still uses an outdated limit on lead in water to decide where and when testing is required,\u201d the report\u2019s author Julie Mutis, a community outreach worker with CELA, said in a news release earlier this month.<\/p>\n
\u201cOntario is allowing children in schools to drink water that would be considered unsafe in most of the country. And that is not acceptable.\u201d<\/p>\n
\u2018More dangerous than we previously thought\u2019<\/p>\n
Mustis added that lead in school drinking water is \u201cmore dangerous than we previously thought,\u201d especially for children.<\/p>\n
\u201cOther provinces and territories are responding to this science with the seriousness it demands, but Ontario has fallen behind,\u201d she said.<\/p>\n
\u201cAlthough Ontario has been regulating lead in school drinking water since 2007, children continue to be exposed to it today. Ontario has gone from a leader in school drinking water safety to the bottom of the class.\u201d<\/p>\n

water A new study conducted by more than 120 journalists and 10 media groups has found that some Canadian cities have higher levels of lead in their drinking water than Flint, Michigan, which has become synonymous with contaminated H20. (Daria Shevtsova) Province has \u2018comprehensive\u2019 testing, mitigation strategy<\/p>\n
Gary Wheeler, a spokesperson for the Ontario Ministry of Environment, Conservation and Parks, said the province makes sure Ontarians have safe drinking water through \u201ccomprehensive\u201d testing and mitigation strategies. <\/p>\n
\u201cEvery fixture used to prepare food or provide drinking water to children in schools, private schools, and childcare centres must be tested for lead. Facilities are also required to flush their plumbing on a daily or weekly basis, depending on the most recent fixture test results,\u201d Wheeler said in a written statement provided to CP24.<\/p>\n
\u201cWhere lead levels exceed the provincial drinking water quality standard of 10 micrograms per litre (10 \u00b5g\/L), facility owners\u2014such as school boards and the operators of private schools and childcare centres\u2014must take immediate corrective action as directed by the local medical officer of health.\u201d<\/p>\n
Quebec has most rigorous school drinking water lead regulations in Canada <\/p>\n
Quebec has the most rigorous regulations<\/a> in Canada when it comes to lead in school drinking water. <\/p>\nSince 2019, it has required all school water fixtures to be tested and progress reports on lead removal from schools are made publicly available.<\/p>\n
According to CELA, since completing a screening of all taps and fountains in the summer of 2021, 61 per cent of non-compliant taps in public schools have been removed, replaced, or made safe to use.<\/p>\n
\u201cOntario needs to follow the rest of the country and recognize that no amount of lead is safe, prevent lead exposure using the most up-to-date mitigation methods, and improve how information about school drinking water is shared with parents,\u201d Mutis said.<\/p>\n
Negative effects of lead<\/p>\n
Lead, which is a metal found naturally in the environment, can be a health risk, as it can negatively affect the development of the brains of fetuses, infants, and children. According to Health Canada, exposure to lead in drinking water can cause effects on neurological development and behaviour, like a lower IQ in children and increased blood pressure or kidney problems in adults.<\/p>\n
Lead is more likely to be found in the drinking water of older homes and neighbourhoods, as the National Plumbing Code of Canada had considered it an acceptable material to use in pipes that bring water to homes until 1975.<\/p>\n","protected":false},"excerpt":{"rendered":"Several schools and school boards in the Greater Toronto and Hamilton Area have higher-than-acceptable amounts of lead in…\n","protected":false},"author":2,"featured_media":574512,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[22],"tags":[712,49,48,295,66],"class_list":["post-574511","post","type-post","status-publish","format-standard","has-post-thumbnail","category-environment","tag-apple-news","tag-ca","tag-canada","tag-environment","tag-science"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/574511","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/comments?post=574511"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/posts\/574511\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media\/574512"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/media?parent=574511"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/categories?post=574511"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/ca\/wp-json\/wp\/v2\/tags?post=574511"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
