Abstract
The purpose of this project was to describe and map geologic materials to a depth of 50 ft throughout the state. Two maps constructed for this study show the distribution of sequences of geologic materials and their comparative ratings. Each sequence was rated for the susceptibility of its water-yielding materials (aquifers) to contamination from waste-disposal practices. Ratings were made by comparing the capacities of earth materials to accept, transmit, restrict, or remove contaminants from waste effluents. The vertical sequences, not specific materials, were compared and rated.-from Authors
