Abstract:
The water-level from wells data (wri964195wlmap_gwpts, points) includes groundwater-level measurements from wells that were made specifically for the Salem River study, using a set of strategically selected locations that, along with stream water-level information, provided control for construction of an interpretive water-table contour map. Well selection was based on those wells that were relatively shallow (typically screened less than 150 feet deep) in order to represent shallow (unconfined) groundwater levels. The selected wells were either already existing in USGS’s NWIS database, or selected in the field and then later entered into the NWIS database. This data layer also includes well construction and related measurement information, and is the same as the groundwater-level data and interpretation presented in Johnson and Charles (1997), table 2-1 and figure 2.1, respectively. The study area includes the entire basins of Salem River, Raccoon Creek, Oldmans Creek, Alloway Creek, and Stow Creek, and parts of the New Jersey counties of Cumberland, Gloucester, and Salem. The horizontal datum of the water-levels from wells data layer is NAD 83, and the vertical datum is NGVD 29. The water-levels from wells data is one of four data layers used to present the water-level information for the Salem River study area. The four geographic data layers were developed at a scale of 1:24,000, and consist of; (1) the study area boundary (wri964195wlmap_bndry, polygon), (2) water-levels from wells (wri964195wlmap_gwpts, points), (3) water-levels from streams (wri964195wlmap_stmpts, points), and (4) an interpretive water-table contour map (wri964195wlmap_wlcont, lines). The water-level information represents one part (sheet 2 of 5) of a comprehensive assessment of the hydrology of the unconfined aquifer system in the Salem River study area. The other four sheets of this report are not available in geographic data layer form, but they can be downloaded in PDF format from the complete original report cited herein. The other four sheets comprise information on (1) the hydrogeology and description of the study area, (2) stream discharge and climate data, (3) water quality, and (4) a detailed water-use and water-budget analysis. The digital data sets that support unconfined-aquifer water-levels and interpretations for the Salem River study area are derived from one of nine hard copy published reports which contain similar data and information across other areas of southern New Jersey. Digital data sets for the unconfined-aquifer water-level and interpretive portions from all nine reports are being simultaneously released, motivated by development of an interactive web-viewer tool that enables convenient online viewing of the information (http://nj.usgs.gov/special/web_mapper/). Eight of the nine published reports are from a comprehensive unconfined-aquifer study series; Great Egg Harbor River (Watt and Johnson, 1992), Toms River (Watt and others, 1994), Upper Maurice River (Lacombe and Rosman, 1995), Mullica River (Johnson and Watt, 1996), Salem River (Johnson and Charles, 1997), Maurice River (Charles and others, 2001), Rancocas Creek (Watt and others, 2002), and Atlantic Coastal (Gordon, 2004). The ninth report that contains unconfined-aquifer water-level data and an interpretation is from a comprehensive water-resource study in Cape May County (Lacombe and Carleton, 2002).
Purpose:
The water-levels from wells data for the Salem River study includes groundwater levels, and related site and well construction information that were compiled, along with water levels measured in streams, to construct a water-table contour map. The water-table contour map can be used to provide an interpretive assessment of depth to water, water-table altitude, water-table gradients, and the direction of groundwater flow within the unconfined aquifer system. The study was performed in cooperation with the New Jersey Department of Environmental Protection for their purpose of developing a scientific basis to help address environmental, water-resource management and planning, water availability, water use, and water quality questions.
