hewlett-packard (620-640 page mill road)

620 - 640 PAGE MILL RD.

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 approximately 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. Five municipal backup supply wells draw water from a deeper aquifer located within 3 miles of the site. The nearest residential areas are located approximately 1/8 of a mile northeast of the facility.
