Quin Kinnebrew, RG, REA II

has project experience that includes preliminary environmental site assessments (ESAs), contaminated site investigations, site remediation, underground storage tank (UST) removal, and geotechnical consulting services. Specifically, his experience involves conducting site assessments for real estate property transfers to estimate the extent of soil and groundwater contamination, overseeing and supervising UST and associated piping removal, and conducting remedial investigation and feasibility studies for oil fields.



Site Assessments

• Conducted soil and/or groundwater investigations for both private and public clients at more than 70 properties in Southern California. These included fuel service stations, metal plating facilities, recycling facilities, dry cleaning facilities, manufacturing facilities, industrial facilities, railroads, and oil fields. A number of investigations were conducted in con-junction with local environmental agencies including the Orange County (OC) Health Care Agency, OC Fire Authority, Los Angeles (LA) County Department of Public Works, LA Fire Department, LA and Santa Ana Regional Water Boards, and the Department of Toxic Substances Control.
• Conducted oil field investigations including soil and soil-gas (methane) studies, feasibility studies, and remediation. These generally involved assessing the nature and extent of oil-impacted soil and preparing remediation guidelines during or prior to development. The methane investigations conducted in accordance with the local fire departments' guidelines included soil gas sampling, data interpretation, and design of methane barriers and venting systems.
• Provided on-call environmental services for the Orange County Transportation Authority (OCTA) for two 2-year contracts. This included planning and implementing Phase I assessments and subsurface investigations along the Santa Ana (Interstate 5) and Costa Mesa (55) Freeways. OCTA requested that 10 separate sites, including 13 different businesses, be assessed for potential subsurface soil and groundwater contamination.
• Investigated subsurface soil and groundwater for a fire station impacted by gasoline and diesel contamination. The investigation included drilling and sampling seven borings and converting five borings to groundwater monitoring wells. Groundwater was found to be impacted by free product over a wide area. The contamination was believed, at least partially, to be a result of the release of free product from an adjacent fuel service station.
• Project duties included developing a work plan, planning and conducting field activities, analyzing data, and preparing the final report.
• Conducted a subsurface investigation at a 72,000-cubic yard oil field landfill comprised of stained soil and field equipment in an effort to assess the extent of its potentially hazardous nature. Soil samples collected from more than 30 borings within and adjacent to the landfill were analyzed using a number of test methods. Laboratory and field results were used to prepare a summary of the potentially hazardous nature of the landfill and options for its disposal.
• Conducted a subsurface investigation within planned and existing residential areas of Carson, CA for a petroleum hydrocarbon pipeline release. Partially refined gasoline, diesel, and jet fuels leaking from a 3-mile stretch of pipeline impacted soil and groundwater up to 400 feet from the pipeline.

Site Investigation/Remediation

• The most extensive soil and groundwater assessments have been conducted at metal plating facilities in the Los Angeles area. To date, Mr. Kinnebrew has investigated more than six such facilities, all but two under the guidance of the Department of Toxic Substances Control. Investigations at and adjacent to these facilities included collecting and analyzing soil and ground-water samples, assessing the extent of impacted soil and/or groundwater, and preparing formal investigation reports and/or remedial action plans.
• Provided UST removal services that entailed mobilizing subcontractors for the proper removal of USTs, dispensers, and related piping as well as observing, monitoring, sampling, and documenting these activities. Typically, soil and/or groundwater investigations have been conducted after the submittal of the tank closure reports. To date, three of the service stations have required remedial activities including excavation and off-site removal or soil vapor extraction.
• Conducted more than 60 Phase I ESAs in Southern California for commercial, manufacturing, residential, oil, field and undeveloped properties. Each Phase I ESA was conducted in accordance with ASTM 1527 and lender guidelines. Impacted soil and/or groundwater were determined to exist at more than 10 of the properties assessed.
• Assessed subsurface soil and groundwater at the old city yard of Santa Ana by investigating a total of nine USTs and an unlined dirt hole used as solvent disposal pit. Soil borings, hydropunch wells, and permanent groundwater monitoring wells were used to assess the nature and extent of possible on-site contamination. Once established, a remedial action plan was devised with the Regional Water Quality Control Board and City fire department for soil and groundwater cleanup activities.
• Conducted a subsurface soil investigation for an industrial site contaminated with volatile and semi-volatile organic compounds as a result of a warehouse fire (filled with automotive and household cleaners). Soil samples were collected within and adjoining the warehouse for chemical analyses. Based on results of extensive chemical analyses, the contaminant extent was delineated and a remedial action plan prepared for the removal and disposal of contaminated soil.
• Assessed the extent and nature of potential sub-surface contamination for Signal Hill Oil Field, a 56 acre oil field, within and adjoining oil wells, sumps, and disposal areas. During this investigation, trenches and borings were used to assess the extent of soil contamination in collected soil samples sent for chemical analyses. Based on field observations and chemical analysis results, a report was prepared that described the nature and extent of soil contamination as well as its ultimate disposal.
• Excavated and disposed of (offsite) soil from oil field sumps within the Kraemer Oil Field in Placentia, CA. Excavation activities included an initial historic background review of possible and known sump locations, excavation of potentially impacted sump materials, soil sampling of completed sump sidewalls and stockpiles, infilling and compaction of sumps, data analysis, and report preparation.
