The purpose of this dataset is to show domestic well locations in Maine.
The dataset consists of point locations of domestic wells reported to the Maine Geological Survey. This dataset is based on an original survey of well drillers in the 1970s, a voluntary well driller reporting program in the mid-1980s, and the present mandatory reporting program which relies on the submission of well information by drillers. Wells have been located using GPS coordinates submitted by the drillers, e911 address information submitted by the drillers and/or ownership data and tax records. Roughly 40% of the wells reported to MGS have location data so there are many that aren't located.
