      Title: Geologic map of New Hampshire: Water well inventory
      Geospatial_Data_Presentation_Form: vector digital data
      Online_Linkage: http://pubs.usgs.gov/ds/215
  Description:
    Abstract:
      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.
    Purpose:
      The dataset is intended to provide locations of reported water wells
      that are accurate to +/- 150 feet to enable spatial analyses and
      comparisons of hydrogeologic conditions to be performed by
      geologists, engineers, well contractors, and the public.

  Use_Constraints: User is required to read metadata completely before using the 
data.  The information provided in this coverage is a subset of spatial 
databases developed by the New Hampshire Department of Environmental Services 
(NHDES). Development of these databases is an ongoing project; they may not 
contain all existing and potential sites, stations, or threats. The NHDES is not

Data_Quality_Information:
  Logical_Consistency_Report:
    The data are entered into a database where values are validated
    automatically before being populated into a master table. Maintenance
    of the database is performed on an as-needed basis and corrections to
    the data are made immediately following error discovery. Positional
    accuracy is periodically reviewed by comparing the town reported on the
    well completion report with the town that the well plots in
    geographically. Anomalies are investigated and corrected upon
    discovery.
  Completeness_Report:
    Updates are made periodically to densify the coverage and correct any
    errors that were discovered through QA/QC.
