Project Experience

• Nevada Environmental Response Trust, Henderson, Nevada: Subsurface investigation and groundwater monitoring to address perchlorate and hexavalent chromium impacts to the Las Vegas Wash resulting from former Kerr-McGee/Tronox operations. Responsible for the assessment of shallow groundwater to assess effectiveness of the ion exchange treatment system in place at the site.

• Lockheed Martin Space Systems, Littleton, Colorado: Groundwater monitoring under the Colorado Department of Public Health and Environment (CDPHE) for effectiveness of bioremediation strategies at Air Force Plant Peter J. Kiewet and Sons Superfund site resulting from former testing of Titan rockets. Contaminants present are trichloroethylene (TCE) and N-nitrosodimethylamine (NDMA).

• Site of Former Refinery, Burkburnett, Texas: Phase I, II, and III ESA’s at the site of a former refinery with ground-surface oil seeps. Site investigation included temporary and permanent monitoring well installation and a pump test for groundwater classification with the TCEQ. Assisted in preparation of reports for all phases to include an Affected Property Assessment Report (APAR). Supervised subcontractors for removal of a historic pipeline, buried metal debris, and impacted soil. Provided client regulatory guidance to comply with Texas Commission on Environmental Quality (TCEQ) requirements during site redevelopment.

• Electrical Equipment Manufacturer, Amarillo, Texas: Quarterly and annual hazardous waste delisting sampling and regulatory reporting for wastewater treatment sludge (F006) generated from the electroplating of gray iron sandcast parts under Resource Conservation and Recovery Act (RCRA).

• Former Home Manufacturing Site, Wichita Falls, Texas: Delineation of vinyl chloride and TCE in groundwater at the site of a former manufactured home production facility owned by the City of Wichita Falls. Prepared an APAR, conducted a Drinking Water Survey Report, and assisted with obtaining Municipal Setting Designation (MSD) status approval from the TCEQ.

• Brine Release Investigation, Jermyn, Texas: Brine release investigation at an oil and gas lease in accordance Texas Railroad Commission (RRC) standards where release followed the path of a perennial stream. Prepared a detailed report recommending gypsum additives as a cost-effective solution to achieve remediation after constituents of concern were identified above background levels in stock ponds and shallow soil at the site.

• Former NALCO Contaminated Site, Wichita Falls, Texas: Oversight of Phase II field activities and compilation of a technical report for the contamination of shallow groundwater resulting from former chemical operations. Employment of in-situ bioremediation strategies and natural attenuation monitoring to mitigate constituents of concern.

• Underground Tank Removal and Sub-Slab Vapor Sampling, Lubbock, Texas: Management of the installation of temporary monitoring wells to assess groundwater contamination at a gas station and former LPST site undergoing a property acquisition by a national client. Sub-slab vapor sampling at building onsite. Analytical results identified no regulatory exceedances in soil or groundwater at the site. Existing UST system was removed and disposed of in accordance with TCEQ guidelines, to include confirmation soil sampling.

• Leaking Petroleum Storage Tank Groundwater Contaminated Site, Lamesa, Texas: Groundwater monitoring at an LPST site. Oversight of removal of residual fluids from existing USTs at the site. Identification and correction of poor housekeeping practices resulting from currents operations at the site that may be contributing to groundwater contamination on and offsite.

• Leaking Petroleum Storage Tank Groundwater Contaminated Site, Brownfield, Texas: Directed groundwater monitoring activities for two comingled LPST plumes. Supervised decommissioning of remediation system at site and plugging and abandonments of SVE/AS wells throughout the City of Brownfield which involved obtaining property access agreements and right-of-way permits. Site closure was approved by the TCEQ.

• Leaking Petroleum Storage Tank Groundwater Contaminated Site, Mentone, Texas: Geologist for the TCEQ’s State Lead PST Contract investigating a plume resulting from former UST and AST leakage at a historic gas station over the course of 50+ years. Plume had migrated 300+ feet from source location with Non-Aqueous Phase Liquids (NAPL) and Dissolved Phase Hydrocarbons. NAPL in various locations exceed 5’ in thickness. Several Mobile Dual Phase Extraction (MDPE) events were conducted at the site over the course of a year that proved effective in reducing the NAPL.

• Leaking Petroleum Storage Tank Contaminated Site, Amarillo, Texas: Lead environmental professional for TCEQ site closure of a remediated LPST site that utilized SVE/AS. Directed decommissioning of remediation system and plugging and abandonment and vault removal for remediation wells.

• City of Amarillo Groundwater Monitoring, Amarillo, Texas: Well installation in downtown Amarillo as well as quarterly groundwater monitoring and reporting to achieve TCEQ site closure for a former LPST site.

• Spill Prevention, Control, and Countermeasure Plans, National O&G Client, Texas and New Mexico: Project Manager for design of new and update of existing SPCC Plans and Facility Response Plans (FRP) at various pump stations and terminal locations in Texas and New Mexico. Duties included calculations for adequate secondary containment, topographic surveys, recommendations for compliance to the client, and drafting of plans for certification by Professional Engineer (P.E.).

• Groundwater Monitoring at Former Chemical Manufacturing Plant, Pampa, Texas: Project manager for former chemical manufacturing plant with perched groundwater mound and seepage to regional aquifer. Groundwater in perched zone and Ogallala Aquifer is impacted by high levels of benzene, arsenic, and other contaminants. Monitored SVE system for efficiency in lowering contaminants in groundwater and provided recommendations to the TCEQ.

• New Mexico Petroleum Storage Tank Bureau (NMED PSTB), New Mexico: Project management and preparation of RFP/RFQs for NMED PSTB leaking tank sites. Groundwater monitoring, subsurface investigations, reporting, progress tracking, and remedial recommendations for the state of New Mexico.

• Phase I Environmental Investigations, Records Search and Risk Assessments (RSRA), Texas, New Mexico, Oklahoma: Site reconnaissance and report preparation for 50+ Phase I ESAs and related property transactions screenings for industries, gas stations, auto repair shops, dry cleaners, retail, vacant land, oil and gas leases, and more, to include additional scope items such as wetland delineation, lead and asbestos, and threatened and endangered species. Recommendations for Phase II investigations included in reporting as warranted.

• Asbestos Sampling for Pipelines and Tanks, Asbestos Inspections, Asbestos Project Managements, Texas: Former licensed Texas Asbestos Inspector for commercial buildings. Assisted O&G clients in identifying the presence of asbestos at their facilities. Project manager coordinating abatement projects for commercial buildings to satisfy Texas Departments of State Health Services (TDSHS) and the Asbestos Hazard Emergency Response Act (AHERA).
