Facility Description

This property and the surrounding area were historically used for fruit orchards until 1976. During this time pesticides (lead, arsenate, and organochlorine compounds) were widely used. Between 1976 and 1978, the former property owner, Orchard Properties, developed the site for industrial use. Wallace Silversmith Inc. operated on site from 1978 to 1987. Wallace generated hazardous waste through metal degreasing and plating with gold, silver, and nickel. Plating solutions and rinse waters, solvent degreasers, waste water treatment sludge, and plating solutions containing cyanide were stored in three greater than 90 day waste water treatment tanks, as well a sludge holding tank. From 1990 to 1998, Dow-United Technologies (Dow) leased the property from Wallace Silversmith. Dow manufactured aircraft and vehicle components. In 1998, GKN Westland Aerospace purchased the business from Dow. In a separate transaction, the land was later purchased by GKN directly from Orchard Properties in 2002. GKN conducted similar activities to Dow, with the additional use of epoxy resins and small scale painting.
