Durham Groundwater Modeling Maps

These maps were created for the Durham Groundwater Modeling project.

The Town of Durham, in partnership with the Strafford Regional Planning Commission (SRPC), the University of New Hampshire (UNH), and JFK Environmental Services LLC, applied for and received funding from the CWSRF Loan Program to conduct a study to determine the susceptibility of public and private drinking water supplies, private septic systems, contaminated sites, stormwater infrastructure, utilities, roads, and municipal critical facilities in low-lying areas to groundwater rise and saltwater intrusion.

The goal of the project was to improve Durham’s understanding of future groundwater rise vulnerabilities, build off and expand UNH’s ongoing research on the impacts of sea-level rise on groundwater, and ultimately enable Durham decision-makers to better plan for future conditions so that the Town can continue to improve water quality in the Great Bay Estuary.
