The Private Well Network (PWN) is a community-based initiative designed to encourage private well owners to protect their health through regular and affordable testing of well water quality. By sharing water quality test results, aquifer maps and general information about groundwater, the PWN aims to empower private well owners to take the necessary steps to improve their own well water quality and to prevent contamination of our common drinking water sources. The current geographic scope of the PWN is limited to the Township of Langley.
