Abstract:
This dataset is a GIS point coverage of the NJGS/USGS Ambient Ground-Water-Quality Network (AGWQN) monitoring wells in New Jersey. This network is maintained jointly by the New Jersey Geological Survey, NJDEP and the United States Geolgical Survey.

The following is adapted from DeLuca and others, 2002.

The AGWQN is designed to monitor the quality of ground water at or near the water table throughout the State. Shallow ground water is generally the first and most significantly affected part of the ground-water system, and the quality of this water is directly related to human activities at the land surface. The AGWQN is a long-term monitoring network with goals to assess the status of ground-water quality by examining the concentrations of various constitutents that can be used as envirnmental indicators, assess water-quality trends by examining data collected on a 5-year cycle, determine the effects of land use on shallow ground-water quality, identify threats from nonpoint sources of contamination, and identify emerging or new environmental issues of concern to the public.

The network will consist of 150 shallow ground-water wells throughout New Jersey within three land-use types. Sixty wells are, or will be located, in agricultural areas, 60 in urban/surburban areas, and 30 in undeveloped areas within New Jersey's five water regions (WMRs)- Northwest, Northeast, Raritan, Lower Delaware, and Atlantic Coastal. Every year approximately 30 sites are sampled in one or several of the five regions. The cycle of sampling all 150 wells will be completed every 5 years.

This coverage shows the wells installed in the first three years of the study. Thus about 60% of the wells are shown here. This coverage will be updated as more wells are installed.

Results of the sampling are reported by the USGS in their yearly series on water resources data of New Jersey. For example, the results of samples taken in water year 2001 are reported in:

DeLuca, M.J., Hoppe, H.L., Doyle, H.A. and Gray, B.J., 2002, Water resources data New Jersey water year 2001, vol. 3, water-quality data: U.S. Geological Survey water-data report NJ-01-3, 580p.

Purpose:
This dataset was developed to provide in a GIS-compatible format the locations of the NJGS/USGS Ambient Ground-Water-Quality Network (AGWQN) monitoring wells in New Jersey.
