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 ten-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.

Cultural resource review

For ground-disturbing remedial actions to be eligible for grant funding, Ecology or another state or federal agency must consult with the Department of Archaeology and Historic Preservation and affected Tribes before cleanup actions begin. Our cultural resource review webpage has more details about this requirement.
