Watershed Studies

The Pennichuck Corporation has been working since 1998 on a multitude of projects, the majority of which have consisted of watershed studies. These studies, focusing on both the watershed as a whole and specific components such as pollution source identification and sediment tracking, have been instrumental in Pennichuck’s decision-making process regarding future watershed management and water quality improvements.
