The 6,700-acre Hill Air Force Base (AFB) is located in north-central Utah, covering portions of Davis and Weber Counties. The Sodium Hydroxide Tank Site is a 29,000-square-foot area that surrounds two 12,000-gallon underground storage tanks (USTs) constructed in the 1950's. The tanks, approximately 5 feet below the ground surface, are used to store sodium hydroxide (NaOH) solution, which is used as an additive in wastewater treatment at the IWTP. In 1980, an estimated 150,000 gallons of NaOH solution leaked from the inlet connections to the tanks over a 1-year period. A second series of leaks occurred in 1984, releasing approximately 132,000 gallons. The interim ROD limits further degradation of ground water quality as a result of NaOH migration through the unsaturated zone. The primary contaminant of concern affecting the soil is an organic, NaOH.
