Monitoring for Pesticides in Drinking Water
Over 100 wells are monitored annually, including those that provide drinking water to private homes, schools, municipalities, and seniors’ housing facilities. Sampling of the wells is conducted each January/February by departmental staff. The collected samples are sent to a laboratory for analysis. The purpose of the program is to monitor the environment for the presence of pesticide residues. To create a long-term record, the same sites are sampled each year.
Individual site locations are not listed to respect the privacy of the individuals involved, as this is a voluntary program for all participants. The locations of public buildings (e.g., schools and seniors’ housing) are identified.
What resources are available?
A summary document which displays each detected pesticide and its safe drinking water limit can be downloaded under resources. The charts show that all of the pesticide compounds detected are at levels well below safe drinking water limits. A map of the sampling sites and a list of the pesticides tested are also available for download.
How do I access the data?
You can access monitoring for pesticides in drinking water data from the province's open data portal (see resources section for link).
