HISTORIC BASE LINE DATA: 1980 HVCEO
REPORT ON ASPETUCK VALLEY AQUIFER
Located within the upper valley of the Aspetuck River, just east of Redding Ridge (vicinity of Valley and Old Hattertown Roads), this small aquifer (comprising only 0.4 square mile) nonetheless has excellent potential water supply characteristics: uniform confirmed coarse-grained structure and a saturated thickness depth which may exceed 100 feet (USGS data). Site "i" lies just upstream, and the two are hydraulically connected.

Both sites are fortunate in having, at present, only very light development, and with the single exceptions noted below, no serious land use problems. About ½ mile upstream, on a small tributary brook, the Redding town landfill (considered in USGS survey an "open face" dump) lies on a shallow-soil complex; however, there are no reports indicating a presence of leachate contamination in any nearby groundwater (one contaminated well on Great Meadow Rd., probably from domestic sources). A subdivision of 16 homes (2-acre lots, Great Meadow Rd.) is in existence along the west side of the aquifer, and another of 40 2 -acre lots is planned on the adjacent hillside recharge area to the west.

Quite substantial protection is afforded by the uniform low-density residential zoning (Redding-2 acre minimum lots, Newtown-3 acre) by 2 large reserved tracts - Bridgeport Hydraulic Company watershed holdings and State of Connecticut (Huntington State Park), and by wetland regulations. Needed protection measures include monitoring and closing (as soon as feasible) of the landfill, strong wetland protection and sewage disposal standards, and additional open space protection for vital recharge areas.
