Description:

Abstract:

This dataset is a point database representing wells, surface water, or treatment entities that are part of a public water supply system in New Hampshire 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.

Purpose:

Dataset is used by several programs at NHDES to help maintain other water resources, such as source water protection areas and well head protection areas.

Data_Quality_Information:

Logical_Consistency_Report:

Positional accuracy is determined using a Trimble Pro XR GPS unit to collect this data which is real time corrected in the field or post corrected in the office with the differential correction application of the Trimble Pathfinder Office software. Attribute information for public water supplies is maintained by the NHDES Water Supply Engineering Bureau.

Completeness_Report:

Older point data, originally obtained by EPA, is being updated with sub-meter GPS technology. Some 1991 point data was not positionally accurate.

Lineage:

Process_Step:

Process_Description:

The majority of the features (90%) were located using GPS equipment; of these, 87% are differentially corrected, 13% are not. Mylar and paper maps at a scale of either 1:24,000 or 1:25,000 were used to compile the non-GPS?d data. Standard GIS quality control methods were used in compiling digital and non-digital data.
