Grants to prevent or cleanup contamination of groundwater that serves as a source of drinking water.



Eligible applicants include public agencies, non-profit organizations, public utilities, tribes, andmutual water companies.

Contamination in groundwater is defined, and is typically tied to exceedances of a primaryMaximum Contaminant Level or notification level.

Typical projects funded in previous rounds include primarily extraction and treatment systems, as well as seawater intrusion prevention projects, and well abandonment projects.

Costs that identified responsible parties are able and willing to pay are not eligible.

Typical match is 50% of the total project cost, with reductions considered for disadvantagedcommunities.

Round 3 is for implementation projects only. Implementation proposals should demonstrate positive, quantifiable environmental outcomes, and consistency with the Prop 1 GWGP Guidelines. Full design is not necessarily required for the award of implementation funds but the intent, scope, and budget for the project should be reasonably well developed, at least at a conceptual level.

Eligible costs incurred after November 4, 2014 may be claimed for match. Reimbursement of eligiblecosts will not occur until after agreement execution. The grant agreement will indicate the eligible startdate, after which eligible reimbursable costs may be incurred. For the purposes of the Concept Proposal, applicants can assume an eligible start date of approximately July 1, 2022.
