This site is a former pesticide formulation and packaging facility, and was the subject of corrective action by USEPA in 1982. Deterioration of the containment cap has raised concerns over potential health impacts from chlorinated pesticides.
Contamination of surrounding properties was addressed by previous TCEQ actions.
Monday night: EPA personnel attended and participated in a community meeting at the Mission Community Center to describe the assessment activities and answer questions.
Tuesday: Sampling activities began. The geoprobe team completed five holes. The wipe sampling team completed floor sampling in the main building.
Upwind and downwind Mini-Rams are operating to collect particulate samples, which will be analyzed for pesticides.
Personnel used a manlift to access the top of the tanks and evaluate approach angles and points of entry for sampling. Each tank has a screw-on cap and pipe extending through the manway. The sampling team applied tools and tested approach angles and work areas to optimize chances of successful entry.
