Aquatic Field Surveys at Longhorn and Louisiana Army Ammunitions Plants. Volume 1. Longhorn Army Ammunition Plant.

摘要

In October and September, 1974, field collections were made from streams and a waste pond on U.S. Army property at the Longhorn Army Ammunition Plant near Marshall, Texas. The objective of the study was to determine whether the potential discharge of munitions and related chemical effluents was exerting deleterious effects on the receiving water biota. Parameters examined included phytoplankton, zooplankton, periphyton, benthic invertebrates, fish, and a variety of chemical measurements. Conclusions reached included the following: (1) Statistically, there were insufficient differences in samples from potentially affected streams and the control stream to conclude that biologic differences due to munitions waste exist. (2) Evaluation of data was hampered by the fact that no adequate analytical technique exists for measuring trace amounts of TNC in water.
