The boundaries of the Aquifer Protection District are those areas designated as "Stratified Drift Aquifer" and Stratified Drift Aquifer Over Glacio-Estuarine Silts and Clays as found on the Map entitled Saturated Thickness and Transmissivity of stratified Drift in the Exeter, Lamprey, and Oyster River Basins, Southeastern New Hampshire, (Study entitled Geohydrology and Water Quality of Stratified-Drift Aquifers in the Exeter, Lamprey and Oyster River Basins, Southeastern New Hampshire, WRI 88-4128, published in 1990); and areas designated as Fine-Grained Stratified Drift, Coarse-Grained Stratified Drift or Coarse-Grained Stratified Drift Overlying Fine-Grained Stratified Drift, as found on the map entitled Saturated Thickness, Transmissivity, and Materials of Stratified-Drift Aquifers in the Lower Merrimack and Coastal River Basins, Southeastern New Hampshire, (Study entitled Geohydrology and Water Quality of Stratified-Drift Aquifers in the Lower Merrimack and Coastal River Basins, Southeastern New Hampshire, WRI 91-4025, published in 1992).
Zone A is that area of the aquifer delineated as a result of a detailed USGS study of the Kingston area aquifer within the Merrimack River Watershed (Stekl and Flanagan, 1992) that shows that the extent and quality of the aquifer is exceptional. A groundwater model developed by the USGS within this report estimates that seven wells pumping a total of four million gallons per day can be sustained by the aquifer (Figure 4). Zone A is the area of the center of Kingston analyzed by this modal and reflected on the accompanying map entitled, "Aquifer Protection District, Zones A and B", available in the Kingston Planning Board office. Zone B is the remaining aquifer area in Town as determined by the two USGS Studies indicated in paragraph one, above.
The Aquifer Protection District is a zoning overlay district which imposes additional requirements and restrictions to those of the underlying, base district zoning. In all cases, the more restrictive requirement(s) shall apply.
