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.
The PWN atlas is provided for informational purposes. Access to the atlas is provided under the following terms and conditions:
- Water samples are taken by well owners or well users in a location of their choice such as a residence tap or other structures on the property, before or after treatment. Water samples are analyzed and provided by Element laboratory.
