It may be cost effective to conduct concurrent assessments for multiple sources in an area. It also encourages regional participation in protection of water supplies. The data gathering part of a source water assessment is the most time consuming. The WDS contains much of the data needed to do delineations and Physical Barrier Effectiveness evaluations, as well as other useful information. Other sources of information include the well drillers' log, DHS or county water system inspection or permit reports, and other reports prepared for the water system.
Maps Get a good map of the source and the area around it.
Until then you may want to obtain a paper copy or one of the commercially available software mapping programs. You may want to supplement the USGS quad map with another local map, such as a parcel, land use or service area map that more clearly indicates the location of PCAs. Other Data For ground water sources, find out if information is available on the ground water flow direction in the area. Determine if any hydrogeologic investigations have been done in the area. Also for ground water sources, find out if there are any nearby abandoned or improperly destroyed wells.
