Pesticide Monitoring in Streams

Surface water from nine rivers is sampled under the Pesticide Monitoring Program. At least three of the nine rivers are sampled each year for a selected number of pesticides. 

Stream water samples and sediment samples are collected once in July, twice in August (once during a normal/dry weather and once during wet weather), and once in September. The two samples in July and September are collected during dry weather. Department staff collect the samples, which are then sent to a laboratory for analysis.

What resources are available?

A summary document, which displays each detected pesticide and its safe stream water limit in a graph format can be downloaded from the resources section. A similar document also displays pesticide detections in finfish showing a Health Canada General Maximum Residue Limit for human consumption. The charts show that all of the pesticide compounds detected are at levels below their respective water quality limits. 

There have been no detections found in the sediment samples. A map of the sampling sites is also available for download.

How do I access the data?

Data on stream water sampling, stream sediment sampling, finfish and shellfish sampling are available through the province's open data portal (see resources section for links).
