Dr. Allison Geiselbrecht, Floyd|Snider Principal, was recently honored by ASTM International’s Committee E50 on Environmental Assessment, Risk Management and Corrective Action for her contributions to the ASTM Standard Guide for Determination of Representative Sediment Background Concentrations (ASTM E3242). This international guide describes a detailed approach for determining representative sediment background concentrations. This is important for delineating sediment cleanup actions, establishing achievable and protective cleanup levels, and selecting technically feasible and sustainable remediation strategies and cleanup goals under various regulatory programs to ensure long-term success.

Dr. Geiselbrecht and co-authors Karen Thorbjornsen and Dr. Shahrokh Rouhani received their Distinguished Service Awards during a remote awards ceremony on October 28, 2020.

Related to this sediment background work, Dr. Geiselbrecht and other members of the Sediment Management Work Group have also published the article “Important Considerations in the Derivation of Background at Sediment Sites” in the journal Integrated Environmental Assessment and Management and developed ASTM Standard Guide for Sediment Corrective Action – Monitoring (ASTM E3164).
