DOE Project Manager Stephen McCracken explains, We owe it to the people of this area to complete our cleanup, establish our long-term monitoring program, and maintain the public awareness of this site into the distant future. The contaminants in the springs around the chemical plant are uranium, nitrate, and nitroaromatic compounds. TCE is localized in the area of the waste pits. Nitrate is in groundwater within the chemical plant area and in the nearby vicinity. Uranium has been observed in monitoring wells adjacent to the waste pit area.
Nitroaromatic compounds occur at low levels in the groundwater beneath the site.
Groundwater beneath the chemical plant is located in the fractured limestone bedrock. The groundwater eventually discharges to nearby springs, primarily Burgermeister Spring in the August A. Busch Memorial Conservation Area northwest of the site. Recreational visitors will not have access to the groundwater. Institutional controls, such as deed restrictions, etc., will be established so that no wells may be drilled for any purpose other than monitoring. Selected Remedy Alternatives that could reduce or remove contaminants from the groundwater were evaluated.
