Drinking Water

For nearly two decades, Silent Spring Institute has studied the role that polluted water may play in the disproportionately high levels of breast cancer on Cape Cod.

Drinking water for Cape Cod residents comes from a sole-source aquifer. The Cape’s shallow water table and sandy, porous soil have made the aquifer particularly vulnerable to land use activity.

Based on their research there, Silent Spring Institute scientists have provided some of the first data to quantify the levels of hormonally active compounds introduced into groundwater from septic systems. They have been able to characterize how these compounds behave as they travel through groundwater systems and measure pharmaceuticals, hormones, and household chemicals in drinking water supplies.
