The Idaho Department of Environmental Quality (DEQ) has awarded $1,501,280 in low-interest wastewater emerging contaminant construction loan funding to the City of Lewiston. The funding will be used to complete an environmental review and address PFAS, pharmaceuticals, and endocrine-disrupting chemicals by installing additional water mains for the East Orchards neighborhood and converting homes from septic to a public wastewater treatment plant.

Why it matters

The details
