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.
Funding cycle
- Amount of funding available: Established with each enacted capital budget
- Grant award limit: $500,000
- Amount of matching funds required: Not required, but we may not fund all the eligible investigation costs
Applications are not being accepted at this time.
The next solicitation will occur in the first quarter of 2026 for potential funding in the 2027–29 biennium. Guidance and instructions will be published no later than January 2026.
