LIAPG presents our next dinner presentation on March 13, 2025! Frederick Stumm PG, Ph.D of the USGS will present An Updated Hydrogeologic Framework and Extent of Saltwater Intrusion in Kings, Queens, and Nassau Counties, Long Island, New York from the Results of Recent Exploration Drilling. Abstract: In 2016, the U.S. Geological Survey began a multiyear cooperative study with the New York State Department of Environmental Conservation to evaluate the sustainability of Long Island’s sole-source aquifer system through hydrogeologic mapping, compilation of groundwater chloride concentrations, and groundwater flow modeling. In the initial phase of the island wide study, the hydrogeologic framework and extent of saltwater intrusion in aquifers in Kings, Queens, and Nassau Counties on western Long Island, N.Y., were investigated. The aquifer system underlying western Long Island has been under stress from pumping of public, irrigation (golf course), and industrial supply wells. Saltwater intrusion has occurred from surrounding embayments (East River, Long Island Sound, Jamaica Bay, and the Atlantic Ocean) due to pumping. Eighteen boreholes were drilled and cores taken during 2019–21 to collect hydrogeologic, geochemical, and geophysical data to delineate the complex subsurface hydrogeology and extent of saltwater intrusion within the study area. Evaluation of the new cores, reexamination of legacy core descriptions, and analysis of borehole geophysical logs was used to refine the previously published hydrogeologic framework of Pleistocene and Cretaceous unconsolidated sediments in the area, including delineation of a previously undefined hydrogeologic unit between the Magothy aquifer and the Raritan confining unit, herein named the “upper Raritan aquifer.” The upper Raritan aquifer was first recognized in southeastern Nassau County from an analysis of about 50 closely spaced boreholes with high- resolution core descriptions and gamma-ray (gamma) logs. Further analysis of borehole logs across the study area indicated that the upper Raritan aquifer was also present in Kings and Queens Counties.

This 2-day course is co-hosted by the Midwest GeoSciences Group and the NYSCPG. The content of this course is designed around the new textbook, Modern Contaminant Hydrology written by Tom Sale and Joseph Scalia (2024). The goal is to advance modern conceptual foundations for contaminant transport in natural subsurface settings in support of better use of finite cleanup resources. Please Note: The April 10-11?Course has Currently reached capacity, but those interested in attending can sign up for a waitlist?here: https://lnkd.in/e-x7uP6P ; a secondary course from April 14- 15 has been made available?here: https://lnkd.in/eQE2h4jR. The new textbook moves away from the conceptualization of a homogenous "aquifer", recognizes the capacities of aquifers to passively assimilate contaminants, and stylistically embraces inherent uncertainties. Central themes include: The paradigm of modern contaminant hydrology has dramatically evolved in the past few years, partly due to how we approach understanding sedimentary sequences in combination with relating secondary alterations from weathering to contaminant occurrence and migration. Subsurface complexities from heterogeneous strata include variability at different scales of transmissive and low permeability zones. Diffusion is a critical process governing storage and release of contaminants in low permeability zones. Transverse mixing of contaminants in plumes is typically a weak process. Blended water quality data from monitoring wells are generally rejected as a basis for studying transport processes. All plausible contaminant phases including gas, nonaqueous, aqueous, and sorbed are interdependent and must be recognized. Reactions including phase changes, sorption, and biogeochemical transformations need to be resolved to understand the behavior of source zones and plumes. Reactions can be distinctly different in transmissive and low k zones. The conventional wisdom of absolute characterization of heterogeneous subsurface settings is often functionally impossible and therefore conceptual models with measurable degrees of uncertainty must be embraced. This 2-day course provides opportunity to earn 16-Professional Development Hours (PDH) plus an?optional 1.5 hour post-course online module. The course also includes a free electronic version of the new textbook, Modern Contaminant Hydrology soon-to-be-announced through Dr. John Cherry's "Groundwater Project". This course preludes with pre-session online assessment for each participant in order to address your questions and topics during the course.

Abstract: The occurrence of per- and polyfluoroalkyl substances (PFAS) in environmental media is not at all an unexpected finding considering the widespread presence of these substances in consumer products, firefighting foams (AFFF), and commercial/industrial materials associated with manufacturing and services. While sources, pathways and receptors may vary from place to place, a ubiquitous presence in the environment is being realized across urban, commercial, industrial and residential land use areas where there are undoubtedly many sources of PFAS to the environment. This situation presents challenges in attribution of impacts to responsible parties, and in an evolving regulatory landscape with few comparative standards and guidance, assessing investigative results to determine what levels constitute the need for some remedial action. This presentation explores several case studies of site investigation for PFAS in environmental media including air, groundwater, surface water and sediment using various techniques to examine source to environmental pathways to receptors for development of conceptual site models that become the basis for determining the need for those remedial actions.
