[edit] Hazardous materials issues

Historically a release of hazardous materials to the environment has occurred at the airport. Groundwater in the site vicinity is perched in a high water table, with depth to groundwater being only seven to ten feet below the surface. Therefore, any release of contaminants to the soil poses a risk to aquifer contamination. The chief hazardous substances of concern at the airport are derived from prior pesticides and herbicides used by crop dusting aircraft; these operations ceased in 1989. At the present time, no such flights are authorized from the airport; in fact, the only hazardous materials presently used and stored at the airport are those associated with the underground gasoline fuel storage tanks. Surface runoff and groundwater flow is generally to the northeast toward the San Joaquin River.

Rinse water from maintenance operations flows into a storm drainage system and pesticide chemicals, which have previously contaminated soil and groundwater on the site, may have been introduced to the environment via this route. Contaminants include S,S,S-tributyl phosphorotrithioate (DEF), dicapthon, and bromophosethyl. These contaminants have been found in wells owned by the Los Banos Community Water District within three miles of the airport.^[1]
