Description: Pursuant to the Groundwater Protection Act section 485-C:5, all groundwater shall be classified for the purpose of prescribing protections and management practices. This layer aptially represents the area(s) listed within RSA, including areas with greater state and local protections. Classifications do not necessarily reflect existing water quality.Reclassification to GAA requires the adoption of a local management program administered by a town or public water supplier to prevent the release of harmful substances that may contaminate groundwater, such as gas or oil.

Description: This dataset is a point database representing wells, surface water intakes that are part of a public water supply system permitted through the Water Supply Engineering Bureau of NHDES. Public water system is defined under the Federal Safe Drinking Water Act. Initial development of the Public Water Supplies coverage was performed by a private contractor (NUS Corporation) for the U.S. EPA, Region 1 during the summer field season of 1991. Following receipt of the data, the NHDES Water Supply and Pollution Control Division's Water Supply Engineering and Groundwater Protection Bureaus performed substantial quality control/quality assurance. In addition, the Water Supply Engineering Bureau and the Water Resources Division's Water Management Bureau located numerous sources that had been missed during the initial data collection or had subsequently been constructed or discovered. Most of the dataset was acquired by GPS and differentially corrected, however a small amount was acquired with various paper reference maps.

Description: This polygon shapefile contains Source Water Protection Areas (SWPAs) for community and non-community, non-transient drinking water supplies. SWPAs contain watershed delineations for surface water intakes and groundwater sources under the direct influence of surface water. The SWPAs use watershed delineations derived from a digital hydrologic unit boundary that is at the sub-watershed (12-digit) level.

Description: Water Supply Intake Protection Areas (WSIPA) are critical lands adjacent to public water supply intakes on surface waters.This polygon shapefile contains WSIPAs for community drinking water supplies.

Description: This data contains the locations of georeferenced water wells that appear in the New Hampshire Geological Survey’s (NHGS) Water Well Inventory database. The database contains well construction details and general geologic information submitted by licensed water well contractors following well completion. The database has been maintained since 1984, the year in which water well drillers were required to begin submitting well completion reports. The data are updated periodically as needed to support ongoing NHGS projects.

Description: This polygon shapefile contains Wellhead Protection Areas (WHPAs) for community and non-community, non-transient drinking water supplies in addition to watershed delineations for surface water intakes and groundwater sources under the direct influence of surface water. The data contains wellhead protection area (WHPA) polygons that represent Phase I or Phase II WHPAs based upon existing hydrologic data or advanced studies. NHDES uses a 500-foot radius circle for protection activities associated with sources for transient systems.

Description: This dataset is a point database representing pumphouses, treatment entities, or atmospheric storage tanks that are part of a public water supply system permitted through the Water Supply Engineering Bureau of NHDES. Public water system is defined under the Federal Safe Drinking Water Act. Initial development of the Public Water Supplies coverage was performed by a private contractor (NUS Corporation) for the US EPA, Region 1 during the summer field season of 1991. Following receipt of the data, the NHDES Water Supply and Pollution Control Division's Water Supply Engineering and Groundwater Protection Bureaus performed substantial quality control/quality assurance. In addition, the Water Supply Engineering Bureau and the Water Resources Division's Water Management Bureau located numerous sources that had been missed during the initial data collection or had subsequently been constructed or discovered. Most of the pumphouses and treatment entities were acquired by GPS and differentially corrected, however a small amount were acquired with various paper reference maps. Additionally, atmospheric storage tanks were located using onscreen remote sensing techniques and aerial imagery.
Description: This dataset includes water and sewer line distribution areas for public drinking water systems with at least 15 service connections used by year round residents or regularly serve at least 25 year round residents.The datasets are based on marked up drawings provided by the survey team. In most cases the lines are interpolated by comparing the markups to aerial and vector basemap data. Once the lines are digitized (heads up method) a 200 ft buffer is applied. The location of the resulting polygon is approximate.
