Abstract

While developed countries have been able to implement engineering techniques and sanitation technologies to keep water resources clean from runoff and ground contamination, air pollution and its contribution of harmful contaminants to our water resources has yet to be fully understood and prevented.

Due to the large spatial and temporal extent and subsequent computational intensity required to understand atmospheric deposition as a pollutant source, a geographic information system (GIS) was utilized. Specifically, the flux of particulate matter at the air – water interface of a lake surface was quantified by season for the year of 2009 for Lake Perris in Southern California.

This project developed a multi-step workflow utilizing a variety of technologies including command line processing, Microsoft Excel, WindNinja, ArcGIS 10.1, 3D and Spatial Analyst extensions, and mathematical formulae provided by the client to process the source information, simulate the behavior of wind, and calculate the spatial distribution of contaminant deposition, as flux, across a selected water body. The deliverables included: a data retrieval processing workflow, datasets used for simulation and analysis, five ModelBuilder models, and maps of analytical results to aid in future lake surface sampling techniques.
