Maine Well Database - Overburden Thickness

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. Data updated 1/26/2026

本数据集收录了向缅因州地质调查局（Maine Geological Survey）报备的家用井点位信息。其数据来源包括1970年代开展的首次钻井商普查、1980年代中期推行的钻井商自愿报备项目，以及当前要求钻井商提交井况信息的强制报备制度。井位坐标通过钻井商提交的GPS坐标、e911地址信息，或结合产权数据与税务记录进行确定。本数据集于2026年1月26日完成更新。
