"GIS AS A TOOL FOR WATERSHED CHARACTERIZATION"
Overview
These days, most new water pollution efforts target "non-point" or diffuese sources of water pollution. Controlling these diffuse sources, typically involving run-off from impervious surfaces, agricultural operations, and suburban lawns, involves evaluating and characterizing the areas draining into sirface waters. A GIS is an obvious tool for this kind of work and this session's speakers discussed how they are using the technology in this context.
Presentations:
Todd G. Fritch, Ph.D., GIS Analyst, Massachusetts Dept. of Environmental Protection
“Using GIS in Massachusetts Source Water Assessment and Protection (SWAP) Program”SWAP is DEP’s program for protecting drinking water sources. Todd gave a brief introduction to the SWAP program, discussed how they are using GIS, and presented the new data that has been developed by the SWAP program.
Dr. Mark Mattson, Environmental Analyst, Massachusetts Dept. of Environmental Protection "Modeling Phosphorus Loading for Total Maximum Daily Loads (TMDL)"This talk introduced the Clean Water Act and the TMDL process and how it is applied to lakes in Massachusetts. Lacking water quality data we calibrated a simple land use loading model to estimate phosphorus loads to lakes and developed new target loads and allocation of phosphorus to the lakes.
Tom Dallaire, Massachusetts Dept. of Environmental Protection
