Alaska DEC Groundwater Plumes - Public

This data set is composed of polygons encompassing the inferred lateral extents of validated contaminant detections in groundwater promulgated in regulations at 18 AAC 75 by the Alaska Department of Environmental Conservation (ADEC). Please note that there may be additional unidentified sources associated with groundwater plumes.
