    Geochemical and Mineralogical Investigation of Elevated Arsenic and Trace Elements in Soils and Sediments of New Jersey Inner Coastal Plain
    (Trenton, N.J. : Department of Environmental Protection, Division of Science and Research, 2024-04) Aziz, Zahid
    Soil cores were collected in 2018 at four locations in the Burlington-Bordentown-Hamilton region of central New Jersey to examine occurrences of elevated concentrations of arsenic (As), vanadium (V), and other metals at various depths in this region. Chemical analyses by inductively coupled plasma atomic emission spectroscopy (ICP-AES) and by portable X-ray fluorescence (pXRF), and mineralogical studies by X-ray diffraction (XRD) and scanning-electron microscopy (SEM) were performed on collected soil samples to evaluate geologic factors that may control the distribution of the high As and V zones in soils.

    Potential Impacts of Climate Change on Groundwater Quality
    (Trenton, N.J. : Department of Environmental Protection, Division of Science and Research, 2023-10) Aziz, Zahid
    This report synthesizes available scientific literature on the potential responses of different hydrogeological and biogeochemical processes to climate change and discusses how these processes could impact groundwater quality. This review suggests that the effects of climate change are likely to cause ephemeral and long-term impacts on groundwater quality driven by modifications of hydrogeological processes, including precipitation, groundwater recharge, discharge, capacity, and seawater intrusion. These modifications would influence biogeochemical reactions and the ultimate chemical fate and transport of contaminants, and are likely to drive the variability of both anthropogenic and geogenic contaminants.
