Map of Surficial Aquifer Potential in Connecticut

The Connecticut Geological Survey's (CGS) map of surficial aquifer potential shows the areas with high potential for groundwater supply based on the thickness of coarse-grained deposits. Colors on the map indicate the thickness of coarse-grained deposits and the thickness of fine-grained deposits where they occur over coarse-grained sediments.
