[2] An investigation by the Oakland Fire Department, Alameda County and the U.S. Coast Guard found over 100 full and empty 5- and 55-gallon drums, some of which were leaking.
[1] The California Department of Transportation (Caltrans), DC Metals, and the Environmental Protection Agency (EPA) conducted an investigation which uncovered chlorinated solvents and other contaminants, including vinyl chloride, and soil gas.
The EPA also collected soil and produce samples in the yards of residences next to the former AMCO facility fence line (on Center and Third streets).
Remediation efforts began with the construction of a ground water and soil vapor extraction (SVE) treatment system.
The SVE ceased operation in July 1998 due to concerns from nearby residents over exposure to fumes from the exhaust of the system.
