Groundwater quantity and quality assessment for aquifer recharge in Ohangwena region, Namibia
… four contaminants namely chloride, Electrical Conductivity, Total Dissolved Solids, and E-coli were studied. The outcomes of this assessment indicated that both Chloride, Electrical conductivity, Total Dissolved Solids, and E-coli concentrations decrease from 1000 mg/l to 0.01 mg/l, 532 mS/s to …

Investigation of Temperature, Solution Strength, and Applied Stress Effects on Cation Exchange Processes in Geosynthetic Clay Liners
… conditions, periodic measurements of electrical conductivity, total dissolved solids, sodium and calcium cation concentration, and temperature of the conditioning fluids were recorded to supplement bound cation complex data. For applied stress conditions, electrical conductivity, total dissolved …

Assessing environmental factors structuring populations and movement dynamics of the invasive snail Tarebia granifera in a subtropical Austral reservoir
… and organic matter (SOM)) and water (i.e., pH, conductivity, total dissolved solids (TDS)) variables. Tarebia granifera seemed to exhibit two recruitment peaks in November and March, identified via size-based stock assessment. Tarebia granifera displayed a significantly greater velocity and …

Geospatial Trends of Per- and Polyfluoroalkyl Substances (PFAS) Incidence in Private Drinking Water in Virginia
… method reporting limits, although median total sum PFAS concentrations were low (1.50 ppt). Short-chain PFAS compounds were more prevalent than long-chain legacy compounds in both total concentration and unique compound detection rates. The USEPA MCL of 4 ppt was exceeded in 2.4% and 5.2% …

Temporal Dynamics of Benthic Macroinvertebrate Communities and Their Response to Elevated Specific Conductance in Headwater Streams of the Appalachian Coalfields
Prior studies have demonstrated Appalachian coal mining often causes elevated specific conductance (SC) in streams, and others have examined SC effects on benthic macroinvertebrate communities using point-in-time SC measurements. However, both SC and benthic macroinvertebrate communities exhibit …
