    Remediation Design and Operation

    LNAPL Technical Director for the Avon Refinery Remediation project in Martinez, California. The facility comprises 2200 acres of refinery in the San Francisco Bay area surrounded by sensitive aquatic environments.  LNAPL remedial approaches and strategies were developed to optimize LNAPL recovery, better integrate LNAPL, groundwater and Waste Management Unit remedial activities and develop end points for closure of remedial operations in select areas of the refinery.

    Technical Lead for the Mc Cooks Metals project in Cook County Illinois, Nigel was responsible for directing the LNAPL investigation, regulatory strategy development and remedial approach for LNAPL at the site. A combination of mobility and recoverability assessments combined with dissolution assessments and fate transport modeling were used to develop a “maximum extent practical” argument for leaving LNAPL in place. Through extensive negotiations and technical demonstrations to the agency the majority of the LNAPL impacted areas were closed as either “deminimus areas” or areas where the “maximum extent practical” end point had already been achieved. Acceptance of the technical and remedial approach prevented Alcoa from having to embark on site wide soil excavation and is estimated to have saved the client over $US20MM.

    Technical Director for remediation projects being conducted on 15 chemical distribution terminals throughout the US. Remediation systems designed, installed and operated under my oversight have included, air sparging, soil vapor extraction, pump and treat (included UV, perozone, activated carbon, slurry phase bioreactors, air stripping, ion exchange resin, metals precipitation, nano-filtration, reverse osmosis), dual phase and multi-phase extraction, in- situ and exsitu chemical oxidation and biological degradation, capping and vertical barrier systems Total expenditures on these remedial projects average approximately $US5MM per year.

    Technical Director for the Piccillo and Davis Superfund projects in Rhode Island. Projects involve investigation and remedial of 2 solvent disposal sites where a combination of BTEX, halogenated hydrocarbons, blended industrial wastes were disposed in the 1980s. Remediation activities have comprised soil excavation, ex-situ thermal desorption, dual phase extraction, and pump and treat. Sequential treatment of the groundwater at the Piccillo site comprised, filtration, chemical precipitation, air stripping, liquid phase carbon and ion exchange resin treatment steps. Of late complex fate transport modeling has been completed at the site to facilitate development of new remedial goals and end points. This has resulted in USEPA approval of shutdown of the dual phase extraction system and conversion of the remedial approach to hydraulic containment only.

    Technical Director and Ashland Project Manager for the Filtrol remediation projects.

    These sites were large industrial facilities where DDT and refinery catalyst were manufactured and investigation and remediation was undertaken. Contaminants treated/managed included heavy metals, petroleum hydrocarbons, chlorinated solvents, DDT and associated Isomers and radioactive Thorium and Uranium wastes. A combination of remedial technologies were utilized at the site included excavation, insitu treatment and capping with total remediation   expenditures   of   approximately $US8.5MM.

Investigation and remediation activities are currently ongoing at these facilities. Senior Project Engineer for NAPL strategy development on the Chevron El Paso, El Segundo and Cincinnati refinery projects. Nigel has been responsible for managing the direction of the engineering technical team in developing and review options for long-term NAPL management, NAPL system optimization and NAPL high grading strategies.

Nigels role on these projects were twofold: facilitate the development of a comprehensive and integrated approach for the investigation and characterization of LNAPL, dissolved and vapor phase impacts at the site. Utilizing this data develop a site conceptual model that can be utilized to demonstrate the relate mobility/immobility of the various NAPL pools and on this basis develop a comprehensive management/remediation plan for NAPL, dissolved phase and vapor impacts.

    Senior Project Manager for the Chevron Bakersfield project. Work included development expansion of the existing SVE system and pilot testing and development of a deep air sparge system to address saturated zone NAPL and dissolved phase impacts. Testing and installation of the air sparge system was conducted approximately 150 feet below the water table to address a NAPL smear zone that extended approximately 130 feet below the water table. In conjunction with this system a gaseous phase nutrient injection system is being installed to stimulate biodegradation of saturated zone impacts Project Engineer for the design, installation and operation of a hydraulic containment and groundwater treatment system at a site within the Charnock well field in Santa Monica, California. The groundwater treatment system comprised a combination of activated carbon and blended media to treat TPHg, BTEX, MTBE and TBA impacted groundwater.  The hydraulic containment systems utilized computer controlled variable speed pumps to maintain constant flows and draw down in the pumping wells and therefore maintain ‘hydraulic containment’.

    Project Engineer for the Lockhead Martin perchlorate pilot test design and construction project. Nigel managed an in-house design and construction team to develop and build a prototypic custom built pilot testing system. The system comprised seven independent fixed bed ion exchange units fully automated and controlled to undergo repeated adsorption and regeneration cycles under different adsorption and regeneration regimes. Both conventional and advanced resins were evaluated using either brine or acid regeneration steps. The pilot test is currently ongoing.

    Project Director for the Mobil Colmslie Terminal Investigation and Remediation Project. This site a 75 acre former bulk fuel storage and lubricant blending manufacturing facility  located  adjacent  to  the Brisbane River has undergone investigation and remediation to facilitate sale and redevelopment. A comprehensive environment investigation has been completed at the site comprising 300 soil bores, 200 test pits and 100 groundwater monitoring wells. On the basis of the investigation results a Phase 2 Investigation, Detailed Human Health Risk Assessment and Remedial Approach have been developed for the site.  On the basis of these documents and comments received from the TPR remedial works commenced in October 2007. To date around 55,000 y3 of impacted soil has been removed and is undergoing land farm treatment.

    Validation sampling and reporting has been completed for the remedial excavations and treated soil and submitted to the TPR as technical memos. These Technical Memos will  be integrated into a final validation report. In conjunction with the soil remediation activities pilot testing of LNAPL remedial technologies has been conducted at the site and a full scale system has been designed and is currently being installed at the site. This full scale system will treat LNAPL impacts over a 4 ha area of the former Terminal. To date approximately $10MM has been spent on investigation and remediation of this site.
