The AMP, Inc. Glen Rock facility is a 20-acre site located in a rural area outside of Glen Rock, Pennsylvania. The facility is the plastics division of AMP, Inc., which manufactures injection-molded plastics and polyester. The materials development lab uses contact adhesives and lubricants. The facility has a permit for managing hazardous wastes. In 1984, employees' complaints about the taste of their water led to testing. Total solvents, some of which are suspect carcinogens were found at many times the federal drinking water standards. Three wells located on the site were tested, and the owners were notified of the contamination. Well water serving an apartment complex also was tested, and the owner was notified of possible exposure to contaminants in the groundwater.
