EcoScience Remediation Service Experience

Remediation Service Experience

Designed, installed, and monitored recovery systems at numerous UST sites in Mississippi, Louisiana, and Arkansas. These recovery systems consisted of trenches, recovery wells, air strippers, liquid-ring vapor recovery pumps, phase-separated hydrocarbon recovery pumps, bioremediation, and natural attenuation.

Installed 199 recovery wells with pneumatic and electric motor-driven positive displacement pumps for the recovery of DNAPL and groundwater with dissolved chlorinated hydrocarbons at a Superfund site in Louisiana. Water was treated with air strippers and carbon. DNAPL and stripped vapors were incinerated. Over 100 million gallons of water and 600,000 gallons of DNAPL have been recovered.

Successfully negotiated with the Environmental Protection Agency (EPA) for application of Monitored Natural Attenuation (MNA) to treat dissolved chlorinated hydrocarbons at a Louisiana Superfund Site. Project included assessment of chemical and physical properties of soil and groundwater, microcosm experiments to determine degredation rates, groundwater and fate and transport modeling for predictive simulations, and long-term monitoring for continued calibration.

Managed assessments and remediation from first response to closure for sites contaminated with petroleum-based materials including #2 Diesel, lubricating oil, and greases, solvents, benzene, toluene, chlorobenzene, ethlybenzene, and chlorinated solvents across the United States for major transportation companies.

Applied bioremediation at a former barge-cleaning facility in Texas. Site was contaminated with petroleum, aromatics, and base-neutral compounds. The project consisted of soil assessment to determine nutrient and microbial count available before treatment, introduction of microbe and nutrients, soil tilling, soil assessment during treatment, and Risk Assessment.

Applied bioremediation to numerous sites containing diesel in shallow groundwater and soil across the United States.

Performed bioremediation projects at major industrial facility to remediate kerosene, chlorinated hydrocarbons, and aniline-contaminated soil and groundwater. Project was successfully completed with one of the first LDEQ-accepted MO-2 and MO-3 RECAP evaluations.

Applied natural attenuation at major industrial site in Louisiana for remediation of chlorinated hydrocarbons, MCB, and TDA. Projects included evaluations of historical data, groundwater assessment, installation of sampling points, modeling, groundwater monitoring, and analysis.
