Worked closely with the analytical laboratories on analytical method modifications needed for some problematic environmental matrices. Evaluated data and assisted in preparing field sampling reports and data quality assurance reports.
Former Chemical Manufacturing Facility, Portland, Oregon — Drafted QAPPs in support of interim and remedial measures for stormwater as well as post-construction stormwater monitoring for site-specific organic and inorganic analytes of concern. Coordinated laboratory analyses of samples. Reviewed and validated analytical results from stormwater interim and remedial measures, and post-construction stormwater monitoring of site-specific organic and inorganic analytes of concern. Prepared data quality assurance reports summarizing data results.
Sampling
Blood Lead Biomonitoring Study, Rico, Colorado — Assisted in developing a biomonitoring study for a former lead mining town in Colorado. Prepared a QAPP for the study, coordinated field activities with the analytical laboratories, validated analytical results, and prepared a quality assurance data report. Sampled media included blood, house dust, drinking water, and paint. Results of this study were used to evaluate seasonal fluctuations of blood lead levels in town residents and to assess the effectiveness of soil remediation efforts.
Subslab Gas Sampling, Milwaukie International Way Site, Milwaukie, Oregon — Participated in semiannual subslab gas sampling. Soil gas probes were installed and sampled following EPA guidance, Standard Operating Procedure (SOP) for Installation of Sub-Slab Vapor Probes and Sampling Using EPA Method TO-15 to Support Vapor Intrusion Investigations. Reviewed and validated analytical results from subslab air samples that were collected and analyzed according to EPA Method TO-15. Provided a data quality summary report for each sampling event.
Semiannual Groundwater Sampling at a Former Wood Waste Disposal Landfill, Oakridge, Oregon — Collected groundwater and surface water samples at a former wood waste landfill site. Analyzed field and analytical data to modify an existing environmental monitoring plan for the site that included a reduced list of analytes.
Human Health Risk Assessment
Human Health Risk Assessment at Smelter Facility, La Oroya, Peru — Assisted in developing a human health risk assessment for an active smelter. Prepared a study QAPP, coordinated field activities with the analytical laboratories (international and domestic), validated analytical results, and prepared a quality assurance data report. Also participated in one of two field sampling efforts in the community surrounding the smelter to characterize exposure media, including drinking water, surface soil, outdoor dust, and dust in homes. These data were combined with biomonitoring and dietary intake data for the population and air dispersion and deposition modeling results to complete the human health risk assessment. For this project, all communications occurred in Spanish.
Data Quality Assurance
Post-construction Groundwater Monitoring Program, Smeltertown Superfund Site, Operable Unit No. 1, Salida, Colorado — Provided data validation services for a groundwater monitoring project. Analytes of interest included select metals and semivolatile organic compounds. Provided a data validation summary report.
Water Quality Monitoring for Mining Site, Ketchikan, Alaska — Prepared QAPPs in support of routine monitoring of surface water and groundwater quality, and quarterly monitoring of the wastewater treatment facility effluent for the site barge, which houses onsite employees. Reviewed and validated analytical results from quarterly groundwater, surface water, and wastewater treatment facility effluent from the site barge. Assisted with quarterly and annual data evaluation, reporting, and development of a database for analytical results.
Volcanogenic Massive Sulfide Project, Alaska — Prepared a QAPP using Alaska Department of Environmental Conservation guidance in support of assembling a sufficient data set to define baseline conditions for target analytes in surface water. Analytes of interest included conventional parameters, cations/anions, and total/dissolved metals. Baseline water quality data were used to characterize water quality typical of the project area prior to any potential underground exploration or mine development. Monitored laboratories’ progress on sample analyses. Reviewed and validated analytical results from baseline water quality testing. Provided data quality reports summarizing analytical results and assisted with development of a database for analytical results.
Glenbrook Nickel Site, Coos Bay, Oregon — Provided data validation services for sediment samples submitted for total organic carbon, grain size, and nickel analyses for site investigation purposes. Responsible for providing a data quality summary report of all analytical results.
Groundwater and Wastewater Sample Data Validation, Blackwell, Oklahoma — Reviewed and validated total and dissolved cadmium, lead, zinc, calcium, and magnesium results from groundwater samples. Reviewed and validated cadmium, lead, and zinc results from wastewater treatment plant influent samples. Reviewed and validated cadmium, lead, zinc, naphthalene, and select volatile organic compound results from groundwater treatment facility samples. Assisted with quarterly and annual reporting of analytical results.
Formerly Used Defense Sites — Performed data validation for munitions-related constituents. Provided data validation reports for each area of concern. Delegated role as lead data validator and performed senior review of data validation results and data validation reports.
Deepwater Horizon, Gulf of Mexico — Worked in conjunction with the natural resource damage assessment team responding to the Deepwater Horizon accident and oil spill in the Gulf of Mexico on behalf of BP Exploration & Production Inc. Provided support to the chemistry technical working group in quality assurance review activities and data completeness tasks. Primarily validated data and provided data validation review support according to project-specific quality assurance plan specifications.
Product Stewardship
Safety Data for Sunscreen Active Ingredients, United States — Supporting the clinical safety assessment of sunscreen active ingredients for the Personal Care Products Council to meet FDA regulatory requirements for the safety of ultraviolet filters. Providing study coordination for the development and manufacture of single active sunscreen formulations that will be used in the clinical trials to be conducted according to FDA guidance.
