Wildlife use of NPDES outfalls at Los Alamos National Laboratory

PDF Version Also Available for Download.

Description

From July through October of 1991, the Biological Resources Evaluation Team (BRET) surveyed 133 of the 140 National Pollutant Discharge and Elimination System outfalls at Los Alamos National Laboratory (LANL). The purpose of the survey was to determine the use of these wastewater outfalls by wildlife. BRET observed wildlife or evidence of wildlife (scat, tracks, or bedding) by 35 vertebrate species in the vicinity of the outfalls, suggesting these animals could be using water from outfalls. Approximately 56% of the outfalls are probably used or are suitable for use by large mammals as sources of drinking water. Additionally, hydrophytic vegetation ... continued below

The purpose of the survey was to determine the use of these wastewater outfalls by wildlife.

Approximately 56% of the outfalls are probably used or are suitable for use by large mammals as sources of drinking water. Additionally, hydrophytic vegetation grows in association with approximately 40% of the outfalls-a characteristic that could make these areas eligible for wetland status. BRET recommends further study to accurately characterize the use of outfalls by small and medium-sized mammals and amphibians. The team also recommends systematic aquatic macroinvertebrate studies to provide information on resident communities and water quality. Wetland assessments may be necessary to ensure compliance with wetland regulations if LANL activities affect any of the outfalls supporting hydrophytic vegetation.
