ace services


The 2.5 acre Ace Services site is a former chrome plating facility where chrome plating was applied to farm implement parts. The facility operated from 1969 to 1989, and was permanently closed in early 1990. From 1969 to 1975, chrome plating waste water generated during operations at the Ace Services facility was discharged directly to the ground surface immediately west of the unnamed tributary to Prairie Dog Creek. A local citizen filed a complaint with the Kansas Department of Health and Environment (KDHE) in early 1971. KDHE and EPA collected waste water samples in 1971 and 1972, that showed the presence of chromium. In 1974 and 1975, concrete retention vats were installed at the Ace Services facility, and an evaporation lagoon was built immediately adjacent to the facility to receive discharged waste water. The evaporation lagoon was not lined, however, and chromium-contaminated waste water was allowed to contaminate soil and infiltrate into the ground. Chrome plating solutions, bulk hazardous wastes, and caustic acidic processing materials contained in vats and drums were p resent at the site. Ground water from the Ogallala Aquifer is the sole source of municipal and private drinking water in and around the city of Colby. The Colby public water supply well No. 8 is located one-fifth of a mile from the site. This well was closed by KDHE in 1980, due to chromium concentrations measuring above Federal drinking water standards. Approximately 6,180 people are currently served by seven Colby municipal drinking water wells. All of these wells are located within a 4-mile radius of the site, and each draws water from the Ogallala Aquifer. The area is an agricultural community with a total population of approximately 6,525, including college students and nearby rural residents. Residences and commercial property surround the site.
