Conceptual bedrock groundwater models in the Newark Basin have evolved with improved characterization tools and shifting project goals. Early equivalent porous medium models overlooked discrete flow and structural controls. The Leaky Multiunit Aquifer System (LMAS) offers a more accurate framework, emphasizing flow through a few conductive bedding fractures. This course outlines LMAS principles and provides 14 practical clues for effective, cost‑efficient bedrock remediation.
This one-hour course introduces industry professionals to borehole geophysics, focusing on geophysical logging and its role in developing and refining a conceptual site model (CSM). Through real-world applications, attendees will explore tool capabilities, data interpretation, and how borehole geophysics can improve environmental site remediation and align with current scientific and regulatory standards.
Despite growing use of advanced borehole logging techniques, data are often underutilized, viewed as localized detail rather than inputs for building site-wide geologic frameworks. This presentation highlights the critical role of log correlation in understanding aquifer systems, illustrating methods and quality control approaches using case studies from New Jersey’s Passaic Formation.
NJ Geological Survey Bulletin 77 compiles research on the geology and hydrogeology of the Newark basin. Chapter F and its appendices summarize 36 projects that used borehole geophysics in 128 wells to study fractured‑bedrock aquifers. The work identifies key water‑bearing features and their structural relationships in sedimentary and igneous units. The talk will highlight how these findings were used to build hydrogeologic frameworks and understand natural cross‑borehole flows tied to groundwater recharge and discharge.
This course explores geogenic contaminants in New Jersey, helping environmental professionals distinguish natural from human-made sources through groundwater data, soil studies, and case-based discussions within the NJDEP framework.
