FY28 Drinking Water Emerging Contaminants
FY28 Drinking Water Emerging Contaminants supports small or disadvantaged Idaho water systems with sampling, planning, design, and infrastructure work to address emerging contaminants in drinking water.
Funder: Idaho Department of Environmental Quality
Due Dates: January 8, 2027 (LOI) | November 9, 2026 (Virtual training) | December 31, 2027 (Planning document, if applicable)
Funding Amounts: Emerging Contaminants for Small or Disadvantaged Communities (EC-SDC) grant funding
Summary: Supports small or disadvantaged Idaho drinking water systems addressing emerging contaminants through sampling, planning, design, and infrastructure improvements.
Key Information: More than 50% of project costs must address emerging contaminants.
Description
The Idaho Department of Environmental Quality (DEQ) administers Emerging Contaminants for Small or Disadvantaged Communities (EC-SDC) grants to address emerging contaminants in drinking water. The program supports public drinking water systems serving fewer than 10,000 people or qualifying as disadvantaged communities under Idaho’s affordability criteria. Contaminants considered in project ratings include PFAS, cyanotoxins, and other contaminants on EPA Contaminant Candidate Lists.
Eligible work includes background sampling, planning, design, construction or upgrades to treatment facilities, new source development, consolidation with another system, and infrastructure for pilot testing treatment alternatives. The program also supports development of new public water systems for people using private wells or surface water intakes. Projects are rated using their proposed activities, documented contamination, sustainability efforts, and affordability or disadvantaged status.
