Beach Water Monitoring Results

During the summer months, the Halton Region Health Department monitors water quality at selected recreational beaches in Halton. This is done as part of the Region’s commitment to protect the safety, health and well-being of all Halton residents.

Beaches in Halton are selected for monitoring based on how often they are used for swimming and other water sports. Visit Testing the Water at Halton’s Beaches for details about the Region’s beach water testing.
