Santa Rosa
Naval Auxiliary Landing Field
Santa Rosa was first commissioned in 1943, as an outlying airfield of Naval Air Station Alameda. There were two 7,000-foot concrete runways. Each runway had a parallel taxiway, and there was a concrete apron in the northwest quadrant of the runway crossing. Two other outlying airfields, Cotati Naval Outer Landing Field and Little River Naval Outer Landing Field, supported Santa Rosa flight operations training 21 squadrons of fighters, dive bombers, and torpedo planes during World War II. The Santa Rosa airfield was relinquished by the US Navy between 1946–48 and reactivated in 1951 for the Korean War. It was abandoned by the Navy between 1952-54.It was re-opened between 1966-67 as a civilian airport, Santa Rosa Air Center. Santa Rosa Air Center closed in 1991.
Active Sites
Sites where military cleanup actions are still ongoing. The risk level of a site refers to a relative risk assessment made by the DOD, which prioritizes the cleanup of sites that pose greatest threat to safety, human health, and the environment.

CONTAMINATED AREAS
Soil: High Risk
Most source areas removed. Some soil remaining from UST. gardening and digging in area
Contaminants: Arsenic 7.9 mg/kg Toluene 25.0 mg/kg Benzene 1200.0 mg/kg Ethylbenzene 6840.0 mg/kg Xylenes 21200.0 mg/kg
Groundwater: Medium Risk
GW is located approx. 1 to 10 feet below ground surface and can easily be monitored for migration. Wetlands in area where GW table is high. This site is located in an area where developement is expected in upcoming years. High groundwater table will be a factor during construction and, if contaminated, poses an identified risk to the workers.
Contaminants: Toluene 0.0 ug/L Lead 0.0 ug/L Xylenes 2.0 ug/L Ethylbenzene 2.4 ug/L Benzene 35.0 ug/L
Sediment (Human): Risk Not Evaluated
Surface Water (Fresh): Risk Not Evaluated
Geological structures present to confine migration. Little potential for movement of contamination and hence little potential for receptors to come into contact with contamination.
Surface Water (Human): Risk Not Evaluated
Geological structures present to confine migration. Potential for access limited.
