    • Nutrient and trace element results for the U.S. Geological Survey vernal ponds study, Pleasant Grove, New Jersey, 2022-23.

    Metadata Updated: October 1, 2025

    This data release contains the concentration results for basic water-quality constituent class parameters (water temperature, pH, turbidity, and specific conductance), total nitrogen, total phosphorous, chloride, and trace elements in surface-water samples collected from two subsites within two vernal pools near Pleasant Grove, New Jersey in 2022-23. In the winter (December 2022 and February 2023) samples were collected at opposing ends of the ponds, or wherever ponding was sufficient for a sample to be taken. An additional sample was collected in July 2023 during the amphibian breeding season. The number of samples collected during each sampling event varied based on water availability and in July 2023 only one sample was collected because Pond 2 was dry. All constituents were analyzed at the U.S. Geological Survey (USGS) National Water Quality Laboratory (NWQL).
