The health of all Cape Codders – residents and visitors alike – depends on the purity of the drinking water that comes from a sole source aquifer beneath us. Our groundwater system is recharged solely from precipitation.
The aquifer maintains a dynamic relationship with our surface waters. The freshwater from the aquifer feeds our ponds, lakes, rivers, bays and coastal waters.
Our aquifer is extremely susceptible to contamination from various land uses and activities. Wastewater discharge from septic systems increases nitrate levels and can have serious public health implications. Protecting land from development helps preserve the quality of our drinking water and our coastal resources.
