REPORT ON UPPER ASPETUCK AQUIFER
Just upstream from the Aspetuck Valley Aquifer, near the headwaters of the Aspetuck in southwestern Newtown, this long, narrow aquifer of 0.8 mile extends about 2 miles along the stream with its associated wetlands. Land use is rural: a large dairy farm, scattered rural residences and open meadow and woodland.

While the natural recharge area is small, the aquifer is thought to be coarse-grained and probably influences the Aspetuck Valley Aquifer. Watershed holdings (Bridgeport Hydraulic Co.), State Park, low density (3 acres residential) zoning, and wetland regulations provide good protection. Future protection efforts should focus on preservation of open space and strict standards for on-site sewage disposal.
