AOC F Underground Injection Control (UIC) Septic System Site

AOC F is the Underground Injection Control (UIC) septic tank site located near the Enlisted Men’s Club near the former Main Operational Area. This buried (subsurface) septic tank had a capacity of 1,500 gallons, and was used to service the domestic waste from the Enlisted Men’s Club. The tank was closed and a sampling investigation was conducted at AOC F in 1997. No evidence was discovered indicating that hazardous wastes were ever disposed of at this site.

A total of 17 subsurface soil samples were collected from four soil borings, and five groundwater samples were collected as part of the Phase I Expanded PA/SI. Metal concentrations (particularly dissolved metals) are similar to background groundwater concentrations and are due to the suspended soil particles in water. Due to the absence of contamination above the background levels, and the absence of site-related human health hazards from past septic tank use, the site was recommended for No Further Action.
