Air Monitoring Stations

BASES operates a network of air monitoring stations across Sarnia-Lambton to track ambient air quality in near real-time. These stations are independently funded by BASES and operated at arm’s length by a third-party contractor. Data from the stations is publicly accessible through the CASA website, providing residents, community groups, and regulators with timely information about air quality in their area. The network helps identify trends, supports community awareness, and informs decision-making during industrial incidents or other events that may impact air quality.

Downriver Monitoring Station

The BASES Downriver Monitoring Station is independently funded by BASES and operated at arm’s length by a third-party contractor. Located on the Canadian side of the St. Clair River, just south of industrial areas in Sarnia and St. Clair Township, the station continuously samples river water using an automated system. Samples are immediately analyzed on-site, and any unusual readings are shared with BASES members for review. In the event of an industrial incident, all members can access these readings to help guide response efforts.
