System dynamics modeling of nitrogen removal in a stormwater infiltration basin with biosorption-activated media.

abstract：:This study examined the extent to which development and road salting has affected Connecticut's groundwater. We gathered water quality data from different time periods between 1894 and the present and analyzed the data using maps generated with ESRI ArcGIS.
