Detailed Summary

A representative geologic profile for the Cornell region, based on multiple well construction logs, generally shows an upper zone of sand or silty sand, with significant intervals of sand & gravel. Interbedded and sometimes thick clay or silty clay layers are common but discontinuous. Deeper units typically remain unconsolidated sand/gravel, but in some outlying areas, granite or bedrock is encountered beyond ~40-70 ft, often deeper. The aquifer for most residential wells is in sand & gravel at moderate depth, with static water level commonly between 9 and 33 feet below ground surface, and tested yields commonly above 5 GPM, frequently 10-15 GPM or more.
