LDEQ RECAP Environmental Data Validation and EDD Verification

Site: Former Ardis Works - Anderson Island; Shreveport, LA
Client: Conestoga-Rovers & Associates
Program: LDEQ RECAP (Louisiana's Risk Evaluation Corrective Action Program)
Guidelines: USEPA CLP National Functional Guidelines (NFG); USEPA Risk Assessment Guidance for Superfund (RAGS); and USEPA Guidance for Data Useability in Risk Assessment
Parameters: BTEX, PAH, Criteria Work Group TPH (VPH and EPH), Metals
Samples: approximately 220 soils
Function: QAA completed the data validation, review, and useability determination per RECAP requirements for the Site-Wide Characterization and the AOI Phase I Assessment at this site. QAA also examined and made necessary corrections to the EDD (Electronic Data Deliverable) so that all submitted results were correct and in the appropriate format. Due to the complex nature of the samples, numerous QC issues arose for this project. Through extensive communications with the laboratory, QAA was able to thoroughly document and investigate the analytical difficulties encountered and qualify the data accordingly. QAA's detailed report allowed the user to understand and account for the data qualifications and as a result, the project was able to proceed without re-sampling.

· NPDES Permit Compliance Audit and Data Review

Site: Offshore Drilling Platforms, Louisiana
Client: Major oil company
Program: NPDES Permit Compliance (Permit GMG290000 for Discharges of Synthetic Drilling Fluids)
Guidelines: USEPA CLP National Functional Guidelines (NFG); USEPA Guidance on Evaluation, Resolution, and Documentation of Analytical Problems Associated with Compliance Monitoring (the "pumpkin" book)
Function: QAA assisted the client in complying with the modification to permit GMG29000. QAA developed procedures and performed the first-ever audits of mobile laboratories on eight offshore drilling platforms. QAA also developed procedures and performed data validation of the mud certification laboratory results.

· USEPA Region 2 Quick-Turnaround Data Validation

Site: Pedricktown Superfund Site; Pedricktown, NJ
Client: Entact Inc.
Program: CERCLA
Guidelines: USEPA Region II SOP HW-6 for organics data; USEPA Region II SOP HW-2 for metals data; and USEPA Region II SOP No. HW-7 for TCLP data
Parameters: Total and TCLP Metals (Lead), Semivolatile Organics (SVOC), Volatile Organics (VOC)
Samples: over 1000 soils and 40 waters
Function: After developing procedures approved by the agency, QAA performed the data validation, review, and suitability determination for all samples at this site. Due to limited space at the site, most of the work required a 24-hour turnaround so that the stabilized material could be immediately disposed of off-site. QAA met this schedule for over 2 years.

· Development of Performance Based Validation Procedures

Site: Intertek Testing Services (ITS); Richardson, TX
Client: TNRCC (now the TCEQ)
Program: RCRA, CERCLA, NPDES, TRRP
Guidelines: USEPA CLP National Functional Guidelines (NFG)
Parameters: GC and GC/MS analytes (volatile and extractable organics)
Function: QAA examined GC and GC/MS data from this analytical laboratory, which admitted to providing fraudulent data for sites around the country from 1991-1997. The data was originally processed improperly (peak shaving, peak juicing, and time traveling) in order to make it appear that all QC requirements were met. When re-processed properly starting with archived raw data, the QC deficiencies are uncovered and often call for rejection of the data per traditional validation procedures. The focus of this project was to evaluate the technical validity of the re-processed data and develop procedures that would maximize the amount of usable data. That is to say, the SOP was written to maximize usability of data that is technically valid but not necessarily method compliant. For more information, see the article Performance Based Measurement System (PBMS).

· GC Raw Data Reprocessing

Site: Confidential
Client: Confidential
Parameters: Pesticides, Herbicides, PCB
Function: Using a dedicated computer loaded with Hewlett Packard data processing software (EnviroQuan ChemStation), QAA reprocessed archived GC raw data using standardized integrating techniques. QAA then compared the results to those originally submitted by the analyst to determine if fraudulent practices were used to process the data.

· USEPA Region 1 Tier I and Tier III Data Review

Site: Haverhill Landfill; Haverhill, MA
Client: Camp Dresser & McKee Inc.
Program: EPA Region I Remedial Investigation
Guidelines: USEPA Region I Data Validation Functional Guidelines for Organic Analysis; USEPA Region I Data Validation Functional Guidelines for Inorganic Analysis
Parameters: VOC, SVOC, Pesticides, PCB, TPH, Metals, Miscellaneous Wet Chemistry
Samples: approximately 130 groundwater and 30 sediment samples
Function: QAA performed a data validation and review of all data from one year of quarterly monitoring in support of a Comprehensive Site Assessment, which included extent of contamination studies and risk assessment. The QAPjP called for a Tier I review on 80% of the data with a Tier III review on 20%. The client stated that the agency representative considered QAA's reports to be excellent.

· Data Review for Phase II Property Assessment

Site: Confidential
Client: Confidential
Guidelines: USEPA National Functional Guidelines for Organic Data, USEPA Region IV Data Validation SOP for PCDD/F Analysis by HRGC/ HRMS, USEPA National Functional Guidelines for Inorganic Data, DOE Evaluation of Radiochemical Data Usability
Parameters: VOC, SVOC, Herbicides, Pesticides, PCB, PCDD/ PCDF, Metals, Radiochemistry
Samples: approximately 20 aqueous and 10 soil samples
Function: QAA performed a Level IV data validation and review of all data for this Phase II property transfer using performance-based control criteria. The complex nature of the samples and analytical instrument problems resulted in several QC deficiencies, which QAA concisely reported in tabular format for easy assessment by the user.

· Resolution of Data Quality Problems for a High Profile Site

Site: Carver Elementary School; Baytown, TX
Client: ERM-Southwest, Inc.
Program: RCRA
Guidelines: USEPA CLP National Functional Guidelines (NFG) and USEPA Guidance for Data Useability in Risk Assessment
Parameters: VOC, SVOC, PAH, Pesticides, PCB, Metals
Samples: approximately 350 groundwater and soil samples
Function: QAA performed a Level IV data validation, review and useability determination in two weeks for 250 samples, which had been collected and analyzed prior to QAA's involvement in the project. Low internal standard areas were reported for several of the samples, which indicated reduced instrument sensitivity and thus indefensible reporting limits. After communication with the laboratory, QAA obtained the data necessary to calculate defensible reporting limits for each specific sample using a technique similar to that used for dioxin analysis, thereby eliminating the need for resampling. For the second phase of the project, QAA coordinated with the laboratory and instituted corrective actions that raised the completeness for QC tests from approximately 65% before QAA involvement to over 90% after QAA involvement.

· Total Quality Assurance Services for a Superfund Site

Site: French Limited Superfund Site; Crosby, TX
Client: French Limited Task Group
Program: CERCLA
Function: QAA contracted to provide all QA services for this site, which resulted in cost savings, increased data reliability and enhanced project image. Services performed include:
