Anchor QEA is conducting a review and assessment of water quality data on Green River, collected by our client at over 16 water quality monitoring stations in 2002, 2003, and 2004.  This project is being conducted in preparation for development of river total maximum daily loads (TMDLs).  The large data set includes multiple annual sampling events and parameters including: pesticides, polychlorinated biphenyls (PCBs), semivolatile organic compounds, heavy metals, cation metals, nutrients, and a variety of conventional parameters. 

Anchor QEA’s work includes setting up and maintaining the project water quality database, reviewing results for water quality compliance, evaluating storm and baseflow water quality patterns, calculating storm event mean concentrations, evaluating the water quality variations in sub-basins, relating results to land use, and calculating loading estimates by sub-basin.  The project includes a detailed statistical and correlative analysis of land use patterns using geographic information system (GIS) layers linked to the project database to predict land use loading estimates based on actual and proposed land use patterns under proposed watershed build out conditions.
