Maine Well Database - Unlocated Wells

The table contains the domestic wells reported to the Maine Geological Survey that don't have spatial coordinates. 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. Data updated 1/26/2026本表格收录了上报至缅因州地质调查局（Maine Geological Survey）且未附带空间坐标的民用井数据。本数据集基于三类来源：20世纪70年代针对水井钻井从业者开展的首次调研、20世纪80年代中期推行的水井钻井从业者自愿报告计划，以及当前由钻井从业者提交井眼信息的强制报告计划。本数据集最后更新于2026年1月26日。
