Why did the U.S. Environmental Protection Agency believe the Site poses a risk to human health and the environment?
Prior studies indicated that a number of industrial-related materials are present in some of the soils and shallow ground waters at the Site. Examples include petroleum products, industrial solvents, paint, thinner and lacquers, herbicides, batteries, contaminated and used oil, spent antifreeze, polychlorinated biphenyls, metals. These materials are regulated as hazardous substances and solid wastes under EPA regulations. EPA believed that past releases of these materials at the Site required further study to determine whether they pose a risk to human health or the environment.
