Implementation and Analysis of Snow Removal Wash Water Reuse Research

Five County garages were provided equipment and successfully trained to measure total dissolved solids (TDS), pH, and turbidity of wash water samples on a monthly basis during the 2014-2015 winter season. The overall research objective was to use these three measurements (TDS, pH, and turbidity) to assess wash water quality potential for reuse and/or disposal. Previous research identified copper and zinc as problematic metals and binary decision models were developed using TDS, pH, and turbidity to classify the wash water as “safe” for reuse (71% correct) or disposal (78% correct) and estimate the probability the classification is correct. A filtration unit and particle settling were also assessed to reduce metal concentrations. Wash water quality results, modeling, and cost analysis support cost effective disposal of wash water at alternate Ohio Department of Transportation (ODOT) facilities with sewer access or at a wastewater treatment plant.
