Councillorship

Elected Councilor, Southern California Society for Risk Analysis, 2001-2003

Representative Professional Experience

Provided expert consulting services to Dallas Water Utilities (DWU) in response to the largest surface water impact of MtBE in United States history. Designed and managed the collection of data from surface water, soil and sediments in an effort to track gasoline components released from a substantial pipeline rupture. Participated in numerous public meetings on DWU’s behalf in an effort to keep the citizens of Dallas informed of the risk to their water supply, Lake Tawakoni.

Developed a comprehensive library of research related to the biodegradation of MtBE on behalf of South Tahoe Public Utility District (STPUD) as part of a litigation support assignment. Assisted counsel in the assimilation of various sources of data related to the assessment of the groundwater plumes affecting STPUD’s water supply. Testified on aspects of hydrogeology, fate and transport processes and risk-based corrective action.

Prepared an expert report in defense of litigation on the Stringfellow Superfund Site in Glen Avon, California. The report focused on response actions and costs, movement of chlorinated solvents and metals in groundwater and the contribution of various parties in the matter.

Designed and managed a groundwater dewatering and treatment system as part of the construction of the second largest subterranean parking structure west of the Mississippi River. The primary goal of the project was to lower the groundwater table 20 feet over approximately ten acres and keep the water level down for a two year period. Located in Los Angeles, the 1.2 MGD Gateway Center Water Treatment Plant consisted of extensive pH adjustment, hydrogen peroxide addition for hydrogen sulfide removal and UV oxidation/activated carbon for trace petroleum hydrocarbons and chlorinated solvent removal. A prototype hydrogen peroxide control system was implemented to minimize the hydrogen peroxide usage. The treatment plant discharge limits were set by the NPDES permit and many of the organic compounds were set at the drinking water maximum contaminant level (mcl). Catellus Development Corporation and the Rapid Transit District of Los Angeles were the clients for this project.

Directed the Carson Regional Groundwater Group’s Groundwater and Hydrocarbon Model (CRGGCAD) calibration (Wilmington-Carson, California). The CRGGCAD model consisted of a groundwater flow model, a hydrocarbon flow model and a dissolved phase transport model that interfaces with a comprehensive database from four oil refineries and one distribution terminal. The model consists of a 30 square mile regional model that communicates to five smaller scale model domains (1.5 square miles) through boundary conditions. The calibration of CRGGCAD was performed by using data from 1700 monitoring wells in conjunction with the predictions from the CRGGCAD model. The CRGGCAD model serves two primary purposes: a. The Los Angeles Regional Water Quality Control Board sees CRGGCAD as the result of a unique cooperative effort among five major oil companies and b. The calibrated model is used to investigate a variety of specific remedial alternatives.

Designed a groundwater pump and treat system for a manufacturing Facility in San Fernando, California. A variety of chlorinated solvents were present at the site distributed at varying depths into the groundwater aquifer. A multi-level groundwater pumping scheme was utilized to minimize the potential for further downgradient migration of the plume. Fate and transport modeling was used to examine the effects of pumping would have on the position of the plume at varying depths below the water table.

Determined the performance of ORC® (Oxygen Release Compound) degradation of a gasoline plume in groundwater in Belin, New Mexico. ORC® is mixed with sand (approximately 2-6% by weight), placed into socks of varying diameters and lengths and then placed down wells. The mass of oxygen and BTEX (benzene, toluene, ethylbenzene and xylenes) was calculated from sampling data via numerous data sets spaced days apart. The timed release of oxygen was verified and approximately 75% of the dissolved BTEX mass was removed in 100 days. There were instances throughout the demonstration project where additional mass of BTEX was supplied to the aquifer by changes in water table elevation.

Lead groundwater and water treatment consultant for selected residents of the City of Burbank. The case involved TCE, PCE and chrome contamination of the groundwater supply and the health effects of long-term exposure. Developing a defensible groundwater modeling approach for determining the historical concentrations of various chemicals in the drinking water wells was the primary goal for the case. The soil and groundwater chemical distribution compiled by various government agencies aided in the understanding of the temporal and spatial distribution of potential sources. The incorporation of historical groundwater pumpage from various wells at different depths was critical to determining the past movement of the chemicals in the subsurface. Finally, the sampling of water from the end water user allowed correlation between the groundwater chemical concentrations, pumping and distribution system mixing processes.

Estimated diluent (diesel) volume in the subsurface at a site in Guadalupe, Central California. The site is an oil field approximately 3500 acres in size with 29 known pools of product within its boundaries. The “floating product” spread over an area of approximately 100 acres. The estimated volume was a critical element of the project as it was subject to close scrutiny by the regulatory agencies and the public.

Directed a three-month groundwater and product recovery test via total fluids in a product pool with an areal extent of approximately 50 acres at oil field in Central Coast of California. The monitoring network consisted of eight pumping wells and twenty-one fluid monitoring wells. The results of the test were used to determine extraction well spacings, optimal total fluid flow rates (including product recovery) and pump position within each of the extraction wells.

Implemented a site-specific data analysis and analyzed contaminant transport phenomena to support the source of groundwater contamination was from gasoline as opposed to crude oil. The laboratory estimation of the effective solubility of benzene from a soil sample and the fingerprint of the fresh crude from 9000 ft. below the site formed the basis of the case. A court appointed special master agreed with the technical merit of the arguments put forth.

Directed laboratory feasibility study of the slurry biodegradation of petroleum refinery sludges (K-listed API separator and bundle sludges) for a refinery on Oahu, Hawaii. Numerous surfactants, heating and mixing strategies failed to form a slurry with the sludge. The main conclusion of the study was that the vast majority of the sludge had very limited biodegradability due to its water insolubility. The sludge treatment technology eventually implemented was a thermal process.

Designed and implemented a hydrogeologic investigation of a karstic (coral) formation and conducted detailed ground-water modeling for a RCRA waiver for a refinery on the Island of Oahu in Hawaii.

Designed ex situ bioremediation system for crude oil affected soil in Southern California (KFI Radio in La Mirada). Remediated approximately 10,000 cubic yards in three months with regulatory approval (Los Angeles Regional Water Quality Control Board). The closure of this site was one of the first successful crude oil bioremediation projects in Southern California.

Managed several in situ pilot tests of soil-vapor extraction, bioventing and air sparging. The results and analysis of the testing formed the basis of the design and operation of the remediation systems.

Directed regulatory negotiations for excavation of 100,000+ cubic yards of diesel impacted soils adjacent to the Pacific Ocean. Concerns varied from the protection of endangered species’ nesting grounds to the minimization of product release during remediation. The California Coastal Commission, U.S. Fish and Wildlife, California Department of Fish and Game, California Regional Water Quality Control Board and several public interest groups were participants in the process.

Designed, managed and analyzed data from over thirty groundwater pumping tests. The results of the majority of the tests that were used in groundwater flow models to estimate the design parameters of pump and treat systems. The total flow rates of treatment plants eventually constructed varied in size from 15 to 10,000 gallons per minute.

Performed expert witness strategy development regarding soil and groundwater transport phenomena on numerous projects. A typical task would be the identification of the relevant data at the site followed by thorough technical evaluations. More often than not, analysis and presentation of relatively simple chemical and mass transfer concepts, along with the mass and volume distributions of the chemicals of concern, enabled a defensible portrayal of the key elements of the dispute.

Performed soil and groundwater transport modeling of 1-2 Dichloroethane (DCA), trichloroethylene (TCE), and vinyl chloride (VC) at the Baxter Healthcare Irwindale, California Facility. The purpose of the modeling was to demonstrate limited mobility of the chemicals in soil, to calculate soil and groundwater cleanup levels and to examine the interaction of the various physiochemical processes occurring at the site.

Determined the migration potential of chlorinated solvents in shallow soils to groundwater which was approximately 350 feet below grade. Vapor probes were placed every fifty feet from land surface to the groundwater table for the purpose of measuring the vapor phase concentration of the various chemicals. The vapor phase concentration was compared to the total concentration of chemicals in soil from a soil samples taken adjacent to the vapor probes. The Los Angeles Regional Water Quality Control Board’s position was that this particular facility contributed to the groundwater problem even though there was not evidence of chemicals from the surface to the water table and they want groundwater monitoring wells installed. The case is still pending.

Conducted research in the general area of biodegradation modeling/phenomena in groundwater as part of the United States Department of Energy's Subsurface Science Program. Developing and applying a fate and transport model capable of describing different biodegradation kinetics expanded the research. The developed model was used to examine the interaction of biodegradation, adsorption, advection, and dispersion in stratified porous media at Batelle's Pacific Northwest Laboratory, Richland, Washington.

Wrote sections of the report entitled Basinwide Instream Flow Assessment Model to Evaluate Flow Needs, Bureau of Reclamation, US Department of Interior, Washington, D.C., published in November 1985. A probabilistic model was developed to incorporate hydraulic geometry relationships to average flow parameter values without the necessity of field observations. The results of the model were used to quantify sufficient or minimum flow needed to sustain the aquatic habitat is necessary for satisfactory resolution of water use conflicts and planning of water allocation strategies. Pool and riffle sequences from numerous streams in Central Illinois were correlated to drainage area, slope and other hydrologic variables.

Wrote sections of the report entitled Hydraulic Interaction of the Fox River with Shallow Aquifers, Illinois State Water Survey, published in December 1986. The effect of switching from groundwater to surface water was examined for the community of Elgin by conducting detailed surface water measurements in the Fox River. Water withdrawals from the deep sandstone aquifers were reduced because of steeply falling piezometric levels and declining water quality. The results of the analysis were used to properly manage the withdrawals of water from the Fox River and the groundwater aquifer beneath it.

Supervised data collection and analysis for cost minimization analysis for surface water flow monitoring stations throughout New England for the U.S. Geological Survey, Water Resource Division. Results of the analysis were eventually used to support the elimination of forty percent of the active stations in the district. Also performed pumping and slug tests and installed groundwater monitoring wells at a peat bog located in the “down east” portion of the State of Maine.

Directed water quality monitoring program of a sensitive salmon-spawning area in a brook that ran through the middle of a large interstate construction project for the Maine Department of Transportation. Developed a sediment transport model through the highway construction project in Brewer, Maine. Thousands of turbidity measurements were taken in Felt’s Brook and dozens of tributaries leading to it during the summer of 1983. Developed a model of the exposed fill erosion potential based upon stream turbidity data, rainfall intensity and duration, land and stream slopes, and other environmental data. The multi-variable nonlinear regression model of the construction area, turbidity measurements and other hydrologic variables proved useful to aid in the placement of erosion control equipment. Field responsibility was to inspect the integrity of various erosion control systems
