Tech Talk
DOE’s ALTEMIS Project: Advanced Long Term Monitoring of Complex Groundwater Plumes
April 25, 2023

DOE’s ALTEMIS Project: Advanced Long Term Monitoring of Complex Groundwater Plumes

Florida International University (FIU) is conducting a series of D&D Tech Talks focusing on several D&D topics relevant to the DOE EM Complex. On April 25, 2023, FIU will feature a Tech Talk from Hansell Gonzalez-Raymat a Senior Scientist at the Savannah River National Laboratory (SRNL).

This talk focuses on the DOE-EM project that is funding a National Laboratory team from Savannah River National Laboratory (SRNL), Lawrence Berkeley National Laboratory (LBNL), and Pacific Northwest National Laboratory (PNNL) to establish the overarching framework of long-term monitoring by systematically combining advanced hardware and software technologies. This project is titled “Advanced Long-Term Environmental Monitoring Systems (ALTEMIS)” and is sponsored by the DOE-EM Technology Development Program. The multi-laboratory team is currently developing and testing innovative monitoring strategies, including the use of in situ groundwater sensors, geophysics, reactive transport modeling, and artificial intelligence/machine learning (AI/ML). These monitoring strategies will improve effectiveness and robustness, while reducing the overall cost. Such long-term monitoring is critical for the soil and groundwater remediation sites with passive remediation and monitored natural attenuation (MNA) in order to confirm system stability and the continuing reduction of contaminant and hazard levels, and to detect changes or anomalies in contaminant mobility (if they occur). The project’s demonstration testbed is at the Savannah River Site (SRS) F-Area Seepage Basins.

Hansell Gonzalez-Raymat

Senior Scientist at the Savannah River National Laboratory (SRNL)

Hansell Gonzalez-Raymat is a Senior Scientist at the Savannah River National Laboratory (SRNL). He received his Ph.D. in Chemistry from Florida International University in 2018 and began his career at SRNL in the same year. For the past 4 years, his research has been focusing on metal-contaminated groundwater/soil and developing strategies for long-term monitoring of complex sites. Some of his research include understanding of biogeochemical processes that contribute to the natural attenuation and release of contaminants in wetland areas, iodine speciation and treatment, and uranium attenuation in acidic groundwater. Dr. Gonzalez-Raymat also collaborates in a multi-laboratory research program (ALTEMIS) to improve long-term monitoring strategies to expedite closure of complex sites and potentially reduce costs for groundwater monitoring. Other pertinent professional activities include participating as a team member in several groups with the Legacy Management Lab Network to provide actionable and strategies to LM-site-specific needs.
