Nietch, C., Jim Lazorchak, B. Johnson, N. Smucker, P. Weaver, S. DeCelles, AND S. Guglielmi. Parallel single-species and stream mesocosm exposures for grading major ion effects in doses mimicking energy extraction produced waters. To be Presented at 2016 Fourth Aquatic Toxicology Symposium, Bar Harbor, ME, June 07 - 09, 2016.
Impact/Purpose:
Conduct validation experiments for Total Dissolved Solids (TDS)/Specific Conductivity (SpCond) for Eastern Mid-West - Central Appalachian Streams
Description:
Excess TDS/Major Ionic Stress/Elevated Conductivities appeared increasing in streams in Central and Eastern Appalachia. Direct discharges from permitted point sources and regional interest in setting eco-based effluent guidelines/aquatic life criteria, as well as potential differences among dominant sources guided the design of this study. Not all sources produce the same type of TDS: Ion contents and their relative distribution differ. The focus here was on produced/waste water TDS and in-stream effects.
