Description: The Surficial Aquifer Potential Map of Connecticut is a 1:125,000 scale analysis, identifying areas considered to have the greatest potential for ground water yield. This map has been prepared for statewide ground water resource protection, water management, non-point source pollution prevention, and land use planning. The map was compiled from a geospatial analysis of the surficial materials and thickness of glacial sediments digital data layers of the Surficial Materials Map of Connecticut, Stone and others (1992) and Quaternary Geologic Map of Connecticut and The Long Island Sound Basin, Stone and others (1998, 2005). The map identifies areas with greater potential for ground water development based upon the texture and thickness of surficial aquifer deposits. The resulting hydrostratigraphic units define areas of coarse grained deposits, coarse overlying fine grained deposits, fine grained deposits, and areas where fine grained deposits overly coarse grained deposits. Aquifer deposit thickness intervals are 1-50 feet, 50-100 feet, 100-200 feet, 200-300 feet, and 300-400 feet.
The Surficial Aquifer Potential Map of Connecticut is suitable for regional and statewide water resource planning at 1:125,000 scale, and may be a useful tool for water resource classification relative to potential ground water availability.
