|The Knowles and Andreas public water supply well sites are located in West Newbury, Massachusetts. New geologic mapping was conducted in the vicinity of the well sites to characterize the bedrock geology. The characterization of the bedrock geology is part of an ongoing study on delineating contributing areas to public-supply wells and hydrologic responses to pumping in fractured-bedrock aquifers. The purpose of this study is to describe the characteristics of the bedrock that may influence groundwater flow and to identify potential directions of anisotropy in the fractured bedrock.|
