Abstract:To assist in delineating source water protection areas based on stream flow, a tool has been developed to calculate the time of travel (based on real-time stream flow measurements), decay, and dispersion of a pollutant introduced into surface waters. The tool allows the user to:<list list-type="bullet"> <list-item>select a location on a river to introduce a chemical or biological constituent,</list-item> <list-item>track the pollutant downstream, under real-time flow conditions, to a water supply intake,</list-item> <list-item>further track the constituent to a water filtration plant, and</list-item> <list-item>identify the overall population served by the plant.</list-item> </list>The databases required for this tool include the Enhanced River Reach File (ERF1), the USGS real-time stream flow measurements, and the EPA Safe Drinking Water Information System (SDWIS). The Arcview Network Analyst extension is used to integrate the databases and to provide the user with a tool to quickly assess the consequences of the introduction of a chemical or biological contaminant to the source waters (surface water) of a public water supply.
