Area-wide groundwater investigation grants

We offer grants to help local governments investigate and clean up widespread groundwater contamination.

Every even-numbered year, we work with local governments to understand the 10-year cost of critical cleanup work in Washington. Their responses inform our biennial budget request to the governor and legislature. Our grant managers coordinate applications for grants and loans that receive funding every two years in the approved biennial budget.
