Provincial Water Quality Monitoring Network (PWQMN)

Started in 1964 by the Ministry of the Environment, the PWQMN has as its mandate to collect surface water quality information from strategic stream and river locations across Ontario.  Sustained monitoring is important to assess long-term changes in water quality.

The Raisin Region Conservation Authority (RRCA) has been a participant in the Network since 1976.  Monthly sampling is conducted at 9 locations on the Raisin, Beaudette, Delisle and Garry Rivers.
