Performed RCRA site services, including:

·         RCRA Facility Investigation (RFI) Work Plan for a 700-acre CERCLA site.

·         Developed work plan objectives and procedures, including an electronic database to facilitate massive data compilation, for implementation of the RFI Work Plan.

·         Located, installed, and sample deep soil borings to delineate the horizontal and vertical extent of hydrocarbon contamination.

·         Performed groundwater modeling and aquifer testing to determine the most effective well locations for the development and installation of an interim corrective-measure recovery well system for the removal of contaminated groundwater.

 

Developed a stratigraphic model of the entire 700-acre site to target areas requiring further investigation, and to promote a better understanding of subsurface features and conditions by customers and regulators.

 

Provided geologic and hydrogeologic supervisory, management, design, and implementation services for remediation action at a large CERCLA site in Louisiana, including:

·         Preparation and implementation of an investigative work plan to define geology and hydrogeology of main contaminated area (120 acres), including:

·         Supervising installation and logging of 110 deep soil borings and 70 piezometers to define geology and hydrogeology.

         Using geostatistics to assist in locating significant areas to investigate.

         Developing and using electronic database to evaluate data.

·         Writing a Remedial Planning Activities report with a conceptual design for remediation of one portion of the site using geologic and hydrogeologic data collected at the site.

·         Management of a $3 million annual budget for production, operation, and maintenance of equipment and crews.  Also managed 18-man drilling and soil sampling crew.

·         Preparing and supervising the implementation of a work plan for installation and sampling of 210 shallow soil borings in swamp/bayou area, including:

         Logging and supervising well installation.

         Sampling and analysis of results.

         Providing technical and logistical support for ecological and sediment risk assessment sampling for swamp and bayou environments.

         Evaluating and reporting on data and the sampling results to the EPA and other interested parties.

·         Designing, logging, registering, and supervising installation of 195 recovery wells for removal of hydrocarbon-contaminated groundwater, and compiling well information into an electronic database for use in geologic cross-sections and mapping.

·         Writing and implementing a work plan for installation and sampling of 27 monitor wells, including:

         Supervising installation of the wells.

         Sampling on semi-annual schedule.

         Analyzing sampling data.

         Performing statistical analysis to measure accuracy.

         Reporting sampling results to the EPA.

·         Set-up and operation of an on-site hydrogen gas detector to measure groundwater samples.

·         Identification of three areas for well installation and sampling in order to evaluate the site hydrogeology and target the risk of contaminant migration into the 400-foot sand of the Baton Rouge Aquifer.

·         Preparation of a work plan for installation of wells to sample for hydrocarbons, ions, and dissolved gases.  Later, complied data into electronic database and evaluated and reported the sampling results.

·         Selection of two areas of the site for a natural attenuation study by evaluating existing data on soil and groundwater contamination, installing wells, sampling wells, and analyzing and interpreting the results.

·         Developing plans for monitoring and depicting surface water and groundwater conditions and flow both at and adjacent to the site, including:

         Preparing procedure for measurement of groundwater levels in all wells on a monthly basis.

         Preparing potentiometric maps and hydrographs depicting site conditions using groundwater level data.

         Planning, installing, and monitoring a stream monitoring system, using data loggers to continuously monitor levels in bayous and the Mississippi River to observe recharge effects on groundwater at the site.

·         Participating in development of site models, including:

         Supervising selection of groundwater models and providing technical support in the development and use of the site models.

         Providing technical assistance in development of a 3-dimensional stratigraphic model of areas of the site using Earth Vision software.

·         Planning, constructing, and operating a test tank based on conditions at the site in order to test hydrocarbon flow on a pilot-scale.

·         Providing geologic and hydrogeologic assessment for LDEQ Solid Waste Permit application.

 

Prepared post-closure permit renewal application for a closed Hazardous Waste Management Facility, including preparation of groundwater protection and corrective action plans for monitoring and remediation of demonstrated EDC contamination of soil and groundwater at the facility site.

 

Developed and implemented a work plan for installation of monitor wells, including 400- and 600-ft. wells, to sample for EDC, metals, volatiles, and semi-volatiles for the purpose of groundwater remediation and contaminant plume delineation in an area surrounding a chemical manufacturing facility which had vinyl chloride and EDC contamination of soil and groundwater.

 

Sought and obtained authorization from the federal Environmental Protection Agency for the Louisiana Department of Environmental Quality to administer the LDEQ RCRA I, II, and III Hazardous Waste Programs, and LDEQ Corrective Action Program, in lieu of the federal programs.

 

Prepared new hazardous waste regulations for LDEQ, including:

·         Preparation of the Louisiana Attorney General’s Statements addressing the regulations’ and enforcement program’s consistency with federal regulatory programs for submittal to the EPA in the States application for authorization of LDEQ hazardous waste regulation program.

·         Development of regulations for importation of hazardous waste into Louisiana from foreign nations.

·         Assessment of the environmental and economic impact of proposed hazardous waste regulations on the State of Louisiana.

 

Prepared EPA Grant Packages, including mid-year and end-of-year work plans establishing baseline hazardous waste inspections, permits, and reporting requirements for LDEQ.

 

Prepared responses for, and negotiated with, the Louisiana Department of Environmental Quality regulatory personnel regarding a Compliance Order issued against a chemical manufacturing facility.  The Compliance Order required the facility to modify existing programs for corrective action and remediation of contaminated groundwater, to develop groundwater models of potential contaminant transport, and to accurately delineate the contaminate plume.
