Aquatic Field Surveys at Longhorn and Louisiana Army Ammunition Plant. Volume 2. Louisiana Army Ammunitions Plants.

摘要

Streams and disposal ponds on property of the Louisiana Army Ammunition Plant, near Shreveport-Bassier City, were sampled to ascertain biological and chemical effects of munitions wastes. Sampling was performed in September and October, 1974. Biological parameters included benthic invertebrates, fish, periphyton, phytoplankton, and zooplankton. Supportive chemical data were also obtained. Results showed that there were insufficient differences in samples from potentially affected streams and the control stream to conclude that biologic differences due to munitions wastes exist. No significant levels of munitions were found at any stream station in either September or October. Based on biological findings, the waste ponds fit into two groups, one moderately stressed and one heavily stressed. The amount of stress seemed to be proportional to the amount of TNT, which ranged from <1 to 60 mg/l, in the ponds.
