CEMS March Luncheon – Update on High Resolution Site Characterization (HRSC) Technologies, the New Optical Image Profiler Tool for Identifying LNAPL Fluorescence, and Implications for In-Situ Remediation – March 14 | COEMS

Topic: Update on High Resolution Site Characterization (HRSC) Technologies, the New Optical Image Profiler Tool for Identifying LNAPL Fluorescence, and Implications for In-Situ Remediation

Speaker: John Fontana, PG, President & CEO, Vista GeoScience

High Resolution Site Characterization (HRSC) tools used for environmental site investigation have significantly improved our ability to generate detailed Conceptual Site Models (CSM) that can be used to better understand subsurface contaminant distribution, soil lithologic and hydraulic characteristics.  Previously, some tools were available, such as cone penetrometer (CPT), that could push tools using static weight.  The advent of percussion hammer direct-push technologies created challenges for these tools.  CPT cannot be driven using percussion hammer rigs, but numerous tools have since been developed that can measure soil conductivity, VOCs, LNAPL and hydraulic properties.  These tools include the Membrane Interface Probe (MIP), Hydraulic Profiling Tool (HPT), Laser Induce Fluorescence (LIF).  More recently, more sensors have been combined into one tool, sensitivity has improved, and the overall robust nature of these tools and configurations have improved.   Digital data acquisition and output methods have also significantly improved the data generated by these tools.  The most recent advance in technology released in 2016 is the new Optical Image Profiler (OIP) tool, which maps the ultraviolet fluorescence response of LNAPL (fuels, oils, etc.).  This tool provides a response similar to the LIF-UVOST (Ultra Violet Optical Screening Tool) for petroleum NAPLS using the same principals of petroleum fluorescence, using different optical sensing technologies.  An overview of the current state of HRSC technologies will be presented with emphasis on the latest tools and developments, including a comparison of LIF-UVOST and OIP data acquired at the same site.    Examples of data applications will also be presented along with a discussion on how to apply the data to in-situ remediation applications.
