Purpose The Bristol Aquifer Protection Agency administers the State of Connecticut's Aquifer Protection Area Program for the city. The purpose of the program is to identify critical public water supply aquifer areas and to protect them from pollution by managing activities conducted nearby. The program was established by the State of Connecticut (Sec. 22a-354a et seq.) to address activities that threaten aquifer quality. The City Council designated the city's Zoning Commission as the Aquifer Protection Agency by ordinance in 2004.
