Description: <DIV STYLE="text-align:Left;"><DIV><P><SPAN>WELLBUFFERS contains circular buffers that represent source water protection areas for wells and surface water intakes that serve the public water supply in Maine. Well buffers are proportional to population served and/or by the type of water supply system. These buffers range from 300 to 2,500 feet in radius. Intake buffers represent a 1000 foot radius around the location of a public water supply surface water intake. PWS travel time or probabilistic source protection areas are depicted in WELLMODELS and are not included in this buffer dataset. There are 3 types of public water systems in Maine: Transient Systems (restaurants, boys and girls camps, campgrounds, motels, bottled water companies, etc.); Community Systems (utilities, mobile home parks, nursing homes, etc.); and Non-transient, Non-Community (NTNC) Systems (schools, offices, factories, etc.).</SPAN></P></DIV></DIV>

Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>WELLMODS contains bedrock source water protection areas and sand/gravel aquifer areas with 200-2500 day travel time in with a probability of contributing water to community public water supplies in Maine. The dataset is suitable for mapping at 1:24,000 or larger scale. The Maine Drinking Water Program (MEDWP), in cooperation with the Maine Geological Survey (MGS) has conducted probabilistic digital modeling of the contributing areas to selected community public water supplies. The models were run using the U.S. Geological Survey finite-difference ground-water flow model MODFLOW and the particle tracking package MODPATH. Available geologic and pump test data formed the primary inputs to the models. Additional information on MODFLOW and MODPATH and water resource modeling techniques is available at http://water.usgs.gov/nrp/gwsoftware/modflow.html and http://water.usgs.gov/pubs/twri/twri6a1/ .</SPAN></P></DIV></DIV></DIV>
