Thirty-two years experience in:
Areas of experience include analytical chemistry, chemical engineering, quality assurance, litigation support, and project management. Analytical chemistry work includes sample preparation, gas chromatography, and atomic adsorption analysis. Chemical engineering experience is in the petroleum industry and includes computer process simulation, process design, crude evaluation, manufacturing cost determination, and exposure to all operating areas within a refinery. Quality assurance experience includes assignment as Quality Assurance Manager for a federal Superfund site, laboratory coordination, data management, raw data reprocessing, and data review. Data review has included extensive data validation and usability determinations for numerous diverse projects under various EPA Regions, CERCLA Superfund, Louisiana’s RECAP (Risk Evaluation/ Corrective Action Program), Texas State Superfund, the Texas Risk Reduction Program (TRRP), and the Texas Petroleum Storage Tank (PST) program. Experience in performing TRRP-13 and Texas state Superfund reviews and preparing Data Usability Summaries includes a broad range of sites (e.g., LPST, hydrocarbon processors, automotive parts/ repair, recycling scrap yard, semiconductor manufacturing, nylon manufacturing) and various analytical parameters (e.g., Metals, VOC, SVOC, BTEX, TPH, Herbicides, PCB). Litigation support includes performing literature searches, theoretical chemical calculations, data interpretation/ evaluation, and preparation of expert reports (see Projects - Litigation Support). Project management experience centers on data usability projects for environmental sites involving thousands of samples.
Ms. Scholz is currently the President of Quality Assurance Associates, a limited liability company that provides quality assurance services to the environmental industry and for litigation support. Key projects include:
- Assignment as Quality Assurance Manager for a federal Superfund site, which included preparing the Quality Assurance Project Plan (QAPP), providing analytical expertise to the environmental firm, coordinating with the laboratory, and providing oversight of the Level III or Level IV data validation (primarily electronic) of more than 500 samples submitted for the complete analytical suite (volatile organics, semivolatile organics, RCRA metals, pesticides, and PCBs);
- Comprehensive data validation and usability reviews for several sites under various EPA Regions, CERCLA Superfund, Louisiana’s RECAP (Risk Evaluation/ Corrective Action Program), Texas State Superfund, and the Texas Risk Reduction Program (TRRP-13);
- A third-party audit of on-site laboratory and QA procedures for a major oil company under the NPDES general permit for off-shore oil rigs;
- Litigation support for a case involving alleged eye injury due to toxic chemicals being deposited on ophthalmic surgical instruments during the sterilization process;
- A contract with the TCEQ to develop procedures for salvaging GC/MS environmental analysis data that was improperly processed in order to make it appear that all QC requirements were met;
- A similar litigation support project to determine the effects of improper processing of GC analysis data on the reported results for pesticide/PCBs; and
- The development of algorithms to check for errors and standardize reporting limits in a database containing thousands of records of analytical data for a large contaminated site.
