Underground Injection Control (UIC) Program Background
1974 S f D i ki W t A t (SDWA)1974 Safe Drinking Water Act (SDWA); Reauthorized in 1996
Federal regulations for protection of Underground SourcesFederal regulations for protection of Underground Sources of Drinking Water (USDWs)USDW defined as any aquifer or portion of an aquifer that
li bli t t OR i l th 10 000 /lsupplies a public water system OR is less than 10,000 mg/lTotal Dissolved Solids (TDS) AND of sufficient quantity to supply a public water system
UIC Program regulates underground injection of all fluids – liquid, gas, or slurryq , g , y

Some natural gas (hydrocarbon) storage, oil & gas production activities, and some hydraulic fracturing fluids are exempted
