REPORT ON GREAT PLAIN AQUIFER
A small aquifer in the broad valley of Beaver Brook in northeast Danbury, this site extends north from Interstate 84 to the vicinities of Danbury Town Park on the west and St. Gregory’s School on the east. Its areal extent is about 0.8 square miles.

Although quite fully developed, the area is almost entirely residential and sewered (RA-20 Zone, lot sizes averaging ½ acre per family). Small areas of wetland, some vacant land and 2 schools complete the land use picture.

The single major land use problem at this aquifer lies at its southern edge, near Interstate 84: a major State of Connecticut road salt stockpile which supplies the state road network for the Region. Controls should be established to prevent spillage, leachate and other damages to groundwater, or the storage location removed to a less sensitive site.

Although small in size, this are is composed of coarse-grained material over fine grained, with a hydraulic connection to Lake Candlewood, which infers a major recharge potential.
