Sumas-Blaine Surficial Aquifer Long-term Ambient Groundwater Monitoring

The Sumas-Blaine Aquifer was identified as one of the most severely contaminated aquifers in Washington State. A long-term ambient groundwater monitoring program has been conducted in this surficial aquifer since March 2009. This study is designed to build on previous monitoring efforts to provide an annual assessment of the status of groundwater quality. Additionally, this monitoring program will assist in identifying new groundwater problems that may arise. Twenty-five wells are sampled annually for nitrate, chloride, and bromide. This project will continue as long as funding is available.
