Winter Field Surveys at Volunteer Army Ammunition Plant, Chattanooga, Tennessee.
Abstract
A winter survey was conducted in Waconda Bay, Lake Chickamauga. The Bay is the receiving water for TNT-manufacturing wastes from Volunteer Army Ammunition Plant located northwest of Chattanooga, Tennessee. Field work was carried out in two phases. The first, completed in December, determined flow and dispersion patterns in Waconda Bay, munitions levels in the lake water and sediments and other limnological parameters of the system. The Phase I survey determined that munitions levels were sufficiently high to justify an intensive biological study at a later date and provided data for locating sampling sites covering the full range of concentrations. The second part of the investigation was completed during March and examined the effects of TNT wastes from VAAP on the periphyton and macroinvertebrate communities. The results of the study indicate no environmental effect on periphyton or macroinvertebrates from a complex TNT manufacturing effluent at a total munitions concentration of less than 25 microgram/l. Definite effects were noted during a period when total munitions averaged 500-600 microgram/l with a peak of over 2,000 microgram/l. Concentrations believed to be in the range of 50-100 microgram/l produced minimal effects.
