All of Cape Cod's water resources are linked together by groundwater.

The quality and quantity of our groundwater is of ciritcal importance, as it is the only source of drinking water for most of Cape Cod. Of equal concern are the health and quality of marine waters and freshwater bodies, which are connected to and dependent upon the groundwater for ecological health and sustenance.

These resources provide significant ecomonic and recreational opportunities and serve as a defining characteristic of Cape Cod. Learn more about how our water resources are linked to our water use from the links below.
