Computer models and Geographic Information Systems (GISs) are valuable tools for assessing nonpoint source discharges. Because of the diffused nature and variable flow associated with storm water run-off, it is difficult to design an inexpensive sampling program to assess the impact of nonpoint source pollution. Computer modeling and GISs can help process limited data and make assessments of nonpoint source discharges from both surface water and groundwater sources. Modeling approaches range from simple loading function calculations to the use of sophisticated hydrological and water quality-oriented computer software. GISs have great potential for reducing the cost of assessing nonpoint source pollution.
