Abstract:

This update (2024) includes the major ions and field parameter data from the 6th sampling cycle (2020-2022) of the New Jersey Ambient Groundwater Quality Monitoring Network (AGWQMN). Major ions are defined here as chemical constituents that generally occur at concentrations greater than 1 mg/L in water. The major constituents tested for in the Ambient Groundwater Quality Monitoring Network include: Calcium Dissolved as Ca, Magnesium Dissolved as Mg, Sodium Dissolved as Na, Potassium Dissolved as K, Chloride Dissolved as Cl, Sulfate Dissolved as SO4, Fluoride Dissolved as F, Silica Dissolved as SiO2 and Bicarbonate as HCO3, Carbon Organic Dissolved as C. Concentrations are reported in milligrams per liter (mg/L). The field parameters are also listed under this heading. The parameters are as follows: Water Temperature (°C), Barometric Pressure (mm of Hg), Specific Conductance @ 25 °C (us/cm), Dissolved oxygen (mg/L), pH Field (Standard Units), and pH Laboratory (Standard Units). Samples were analyzed using United States Geological Survey (USGS) National Water Quality Laboratory (NWQL) Schedule 1923, Major Ions and Physical Parameters. Field turbidity is reported based on the specifications of the individual turbidity meters used by each of the sampling groups resulting in different units of measure (NTU, FNU, or NTRU).
New Jersey's AGWQMN is a cooperative program between the New Jersey Department of Environmental Protection (NJDEP) and United States Geological Survey (USGS). The goals of the current network are to determine the status and trends of shallow groundwater quality as a function of land use related to non-point source pollution in New Jersey. This network consists of 150 monitoring wells screened at the water table. Thirty of these wells were sampled per year on a 5 year cycle from 1999-2013. Beginning with the 4th sampling cycle in 2014, the sampling frequency was changed to once every 3 years (3-year cycle). This layer includes data from sampling cycle 6; samples were collected between 2020 and 2022. The New Jersey Geological and Water Survey (NJGWS) manages the network design, well installation, well maintenance, data interpretation, reporting, and a portion of the well sampling. The NJDEP Bureau of Fresh Water and Biological Monitoring and the United States Geological Survey (USGS) collect the remaining ground-water samples and the USGS National Water Quality Laboratory in Denver, Colorado or their contracted laboratories analyzes them. Chemical and physical parameters analyzed at each well include field parameters such as pH, specific conductance, dissolved oxygen, water temperature and alkalinity, major ions, trace elements (metals), gross-alpha particle activity (radionuclides), volatile organic compounds, nutrients, and pesticides.

Purpose:

The purpose for this file is to spatially represent the groundwater quality results from 6th sampling cycle (2020-2022) of the New Jersey Ambient Groundwater Quality Monitoring Network. Ground-water quality data from the Ambient Ground Water Quality Monitoring Network is collected to increase understanding of water quality as it relates to the geologic character of various aquifers and non-point source impacts from land use.
