We make every effort to ensure the data presented here is accurate based on the best available information currently on file with DEC. It is therefore subject to change as new information becomes available. We recommend contacting the assigned project staff prior to making decisions based on this information.


Rapids Camp was established as a recreational facility for troops stationed at the King Salmon Air Station (AS); waste oils, fuels and polychlorinated biphenyls (PCBs) were used and stored at the site. The King Salmon AS has been divided into seven Groundwater Zones for the purpose of site management. Rapids Camp is also referred to as Groundwater Zone 6 (OT032). Rapids Camp Beach Dock (SS005) is a beach area and boat launch within Rapids Camp/Zone 6 (OT032) used by the Air Force between 1952 and 1977. Locals presently use the boat launch area. Drums of gasoline and oil were staged here at one time by the military and fuel contamination was noted in adjacent soils and in the adjacent Naknek River. Remedial excavation occurred and groundwater monitoring wells were installed and monitored. All known contaminated soil above cleanup levels was removed from the site and groundwater monitoring results were below cleanup levels. A ROD for all of Rapids Camp/Zone 6 was signed in June of 2000. No ICs are present at this site. For additional information on Groundwater Zone 6, see the CS Database entry: 2569.38.020 - King Salmon AS OT032 GW Zone 6, Hazard ID (ID): 2633.
