SITE BACKGROUND

Hewlett-Packard manufactured optoelectronic equipment on this 10-acre site from 1962 to 1986. In 1981, at least 300 gallons of waste solvents leaked from an underground storage tank. The company excavated the tank and 100 cubic yards of contaminated soil in 1981 and transported the materials to a hazardous waste disposal facility. Since 1982, the company has been pumping and treating contaminated groundwater from the shallow, chemically affected aquifer.
