Sponsor: Representative Smith, LD 29

Caucus & COW

Overview

Modifies the FY 2024 general appropriations act relating to the Brackish Groundwater Pilot Program (Pilot Program), administered by the Arizona Department of Water Resources (ADWR).

History

Brackish groundwater is groundwater with concentrations of total dissolved solids (TDS) of 1,000 to 10,000 milligrams per liter (mg/L). As background, TDS measures the combined content of all contaminants contained in drinking water. It is often considered a salinity measure because it captures the presence of dissolved inorganic salts like sodium, calcium, magnesium, chlorides, sulfates and bicarbonates. TDS levels are addressed under the National Secondary Drinking Water Regulations of the Safe Drinking Water Act. These regulations are not mandatory but serve as guidelines to help public water systems manage drinking water for aesthetic, cosmetic and technical considerations (42 U.S.C. § 300g-1)(40 C.F.R § 143.1)(40 C.F.R § 143.3).
