As water travels over the surface of the land or through the ground, it dissolves naturally-occurring minerals and, in some cases, radio-active material, and can pick up substances resulting from the presence of animals or from human activity.

Drinking water, including bottled water, may reasonably be expected to contain at least small amounts of some contamination. The presence of contaminants does not necessarily indicate that the water poses a health risk.

The Sandwich Water District  Wells #2, #3, and #9 are located at the Boiling Springs Well Field in East Sandwich; Well #7 is located at the Nye Pond Well Field; Wells #4, #6, and #10 can be found at the Pinkham Road Well Field; Well #11 is located at the Farmersville Road Well Field; and Well #8 is located on Farmersville Road near Newtown Road. Well #5 has been reconditioned and is available for service and is located at Weeks Pond Well Field. Well #1 has been off-line since 1976 and was abandoned in 1998

The Sandwich Water District treats all of its wells for corrosion control. The addition of Sodium Hydroxide raises the naturally acidic pH of the water which reduces the corrosion of household plumbing and lowers exposure to lead and copper. A very small amount of Chlorine is used for disinfections at Wells #2, #3, #5, #7, #8, #9 and #11. In addition, the water in Well # 8 is treated for iron content and Wells #4, #6, and #10 for PCE control.

The Sandwich Water District, is committed to providing consumers with high quality drinking water. Analyses conducted by private certified laboratories are an integral part of ensuring that the water meets or surpasses the state and federal water faucet with water dropletstandards for quality and safety

Community Awareness Tip!

Since the tragic events of September 11, 2001 there clearly is a need to heighten security measures for water supplies and water system infrastructure. Residents are the eyes and ears of the community and we encourage you to call your local police with concerns about suspicious activities, illegal dumping, or other reportable offenses.

Hazardous Waste

The improper disposal of hazardous materials can cause serious contamination to water supplies and the environment. As residents of Cape Cod we all can contribute to protecting our natural resources through proper waste disposal. Do not pour hazardous wastes or paints down any septic systems, private or public drains, on the ground, or into waterways. Safe disposal of materials through the Hazardous Waste Collection Program will help to keep our drinking water and our community pollution-free.
