Data_Quality_Information:
Logical_Consistency_Report: The quality of the wellhead protection area is based on the source data (i.e. Wells, HACS) used to delineate the area.
Completeness_Report: The wellhead protection areas (WHPAs) are delineated using hydrologic areas of concern as a basis for determining surface areas that flow to a surface water body. Where topography does not indicate a definitive divide the larger area is included e.g., where a wetland is located in a saddle between two ridges the watershed delineation includes all of the wetland. The boundaries are being refined as watershed boundaries are improved (i.e. HUC 11, HUC 12) and new surface water sources are permitted.

Process_Step:
Process_Description: The wellhead protection areas are entered in two different ways. Either a paper copy is provided, which is scanned then digitized using the digitizer or an area is created by setting a radius around an existing well.

Ordering_Instructions: Most coverages are available through ftp site (see Online Linkage). To address homeland security concerns, access to some of these data sets is available only to users who present a valid personal identification number (PIN) and password. These data sets have an access constraint set to Upon NHDES Approval. Users can apply for a PIN and password using the OneStop Data Retrieval Registration Form (http://www.des.state.nh.us/gis/onestop/). Applicants should be very specific when providing information on the registration form to enable NHDES personnel to determine their eligibility. For more information on what criteria is necessary to receive a PIN/password please visit http://www.des.state.nh.us/factsheets/co/co-14.htm. Once the applicant has been provided a PIN/Password, the applicant shall be the sole responsible party for the information they receive using the PIN/Password that has been issued to said party. The applicant shall be responsible for the accuracy of the information submitted in a request for a PIN and Password that will allow said applicant to access certain information held by the Department of Environmental Services. The applicant shall understand by submitting a registration form, said applicant shall be responsible for the PIN and Password they receive and for any and all information collected using the PIN and Password, and that NO LIABILITY IS INCURRED BY THE STATE by reason of providing the requested access.
