Also included development of dissolved hydrocarbon/MTBE response action plan to support ongoing analysis of plume stability and natural attenuation outside of LNAPL areas and near property boundaries. Project also included the characterization and response action development for a former SWMU area containing soil impacted above commercial/industrial direct contact cleanup levels.

Provided technical support and guidance for contractors in the field, was the primary author of an annual monitoring/recovery network status report prepared for TCEQ, and developed a Response Action Report to optimize the current monitoring/recovery network and reduce overall compliance load for the client.

Project Manager, Hydrocarbon Recovery System Design and Installation, Corpus Christi, TX, Confidential Client. Designed and coordinated the installation of a groundwater/LNAPL recovery trench to establish a hydraulic capture zone to remove and remediate affected groundwater and reprocess recovered non-aqueous fluid. The collection trench system remains in operation and continues to control local hydraulic conditions, precluding affected groundwater and phase-separated hydrocarbons from migrating offsite. Responsibilities included the system design, reporting, and project management. Served as primary author and PE/PG for several project documents submitted to TCEQ, including an Options Evaluation, Work Plan, and Corrective Action System Installation and Effectiveness Report.

Project Manager, Petroleum Storage Tank Remediation and Groundwater Flow Modeling, , Corpus Christi, TX, Confidential Client. Performed groundwater flow modeling to predict phase-separated hydrocarbons plume migration and effectiveness of an existing groundwater extraction system to control the groundwater and free-phase impacts. Soil and groundwater samples were collected, and an APAR was prepared and approved by TCEQ. The effectiveness of the recovery system and overall Response Action is evaluated annually and reported to TCEQ.

Project Manager, Dona Park Neighborhood Characterization, Remediation, and Air Monitoring, Corpus Christi, TX, Confidential Client. Managed a long-term Ambient Air Quality Program during the demolition and remediation of a former smelting facility. Data were used to confirm that no unacceptable impacts to ambient air were occurring in an adjacent neighborhood. Project involved the installation and operation of particulate monitors and samplers, establishment of a real-time alert system to allow for immediate notification of any action level exceedances, assessment of laboratory analytical data, and the creation and maintenance of an analytical results database available to the public.
