The Pinehills Water Supply

Do you know where your water comes from?

The Pinehills water supply is groundwater drawn from the Plymouth/Carver Sole Source Aquifer.

The recharge area for the water supply is protected by a state designated "Zone II Wellhead Protection Area" which limits the activities that can occur within its boundaries.

What is a Zone II Wellhead Protection Area?

That area of an aquifer which contributes water to a well under the most severe pumping and recharge conditions that can be realistically anticipated (180 days of pumping at approved yield, with no recharge from precipitation).

In all cases, Zone II shall extend upgradient to its point of intersection with prevailing hydrogeologic boundaries (a groundwater flow divide, a contact with till or bedrock, or a recharge boundary).

The key to understanding the water supply is that the groundwater flow under The Pinehills is to the north-east. The Pinehills Water Company wellheads are 1500 feet upstream of The Pinehills Waste Water Treatment Facility (WWTF) and 1/2 mile upstream of the (now closed) Manomet Landfill.

The image below shows the Zone II Wellhead Protection Area (The teardrop shape in the center of the map) surrounding The Pinehills Water Company wellheads and its location relative to the The Pinehills Waste Water Treatment Facility and the Manomet Landfill.

Great Island is on the right-hand side of the map.
State Route 3 (Pilgrim Highway) cuts thru the Zone II.
