Abstract |
The Ordinance Works Disposal Areas site is on the west bank of the Monangahela River in Morgantown, Monongolia County, West Virginia. Several chemical facilities have operated at the site since the early 1940s, producing substances such as hexamine, ammonia, methyl alcohol, formaldehyde, ethylene diamine and coke. The operable unit addresses onsite contamination found in the following areas: an inactive landfill where solid and chemical wastes were disposed of; a scraped area which consists of bare soil adjacent to the landfill where solid wastes were buried; two former lagoon areas which were closed following a cleanup action in 1976; and several streams located in the southern portion of the site. The selected remedial action for the site includes excavation and onsite treatment of approximately 425 cubic yards of inorganic contaminated soil from hot spots in the scraped area and lagoon area using solidification, followed by placement of the treated soil in the landfill before capping; installing a multimedia RCRA Subtitle C cap on the landfill and regarding and revegetation; excavating approximately 13,460 cubic yards of organic-contaminated soil and sediment from the lagoon area, scraped area, and streams, with onsite treatment by bioremediation in a treatment bed; ground water, surface water, and sediment monitoring; and implementing deed restrictions to prohibit residential and industrial construction at the site. |
