About the Superfund Redevelopment Initiative
This nationally coordinated effort provides EPA and its partners with a process to return Superfund sites to productive use. Learn more at Superfund Redevelopment Initiative.
Redevelopment at the Site
The 23-acre American Chemical Service, Inc. Superfund site is located in Griffith, Indiana. A solvent recovery firm, a chemical manufacturer and a chemical drum reconditioning business operated on site. Improper chemical waste disposal practices contaminated groundwater, surface water and soil. EPA added the site to the Superfund program’s National Priorities List (NPL) in 1989. Cleanup activities included treatment of groundwater and contaminated soil and sediment, as well as removal of chemical drums and debris. Long-term groundwater and well monitoring continue. The American Chemical Service continues to manufacture specialty chemicals on 15 acres of the site.
Economic Activity at the Site
As of December 2016, EPA had data on one on-site business. This business employed 5 people and generated an estimated $10,000,000 in annual sales revenue. For additional information click here.
Activity and Use Limitations
At this site, activity and use limitations that EPA calls institutional controls are in place. Institutional controls play an important role in site remedies because they reduce exposure to contamination by limiting land or resource use. They also guide human behavior. For instance, zoning restrictions prevent land uses – such as residential uses – that are not consistent with the level of cleanup. For more background, see Institutional Controls.
The groundwater is contaminated with VOCS including BENZENE, TOLUENE, CHLOROMETHANE, XYLENE, and vinyl chloride; CREOSOTE PENTACHLOROPHENOL (PCP); and PHTHALATES. The shallow aquifer contains the highest amounts of organic contaminants. Soils are heavily contaminated with numerous substances including PCBS, HEAVY METALS, semi-VOCs, COAL TAR constituents, VOCS, and some pesticides.
