Health Assessment for Frit Industries, Walnut Ridge, Arkansas, Region 6. CERCLIS No. ARD059636456

摘要

The Frit Industries, Inc. (Frit) National Priorities List Site is located in Walnut Ridge, Lawrence County, Arkansas. Contamination at the site resulted from piles of raw material, product, and waste material from Frit's fertilizer micronutrient process, which were stored directly on the ground surface without a liner or a cover. Sampling of the surface water and the sediment have historically shown the ditches and Coon Creek to be contaminated with heavy metals, especially cadmium, chromium, lead and zinc. Results from surface water and sediment samples taken in 1985 indicated concentrations of cadmium (14-81 micro g/L), lead (6-20 micro g/L), and zinc (14-18,050 micro g/L) to be of public health concern in the surface water, and no heavy metal concentrations above concentrations of public health concern in the sediment. The site is of potential public health concern. Potential human exposure pathways include direct dermal contact with the soil or surface water, incidental ingestion of soil and surface water, and inhalation of fugitive dust.
