• Assist the Data Validation Group Manager in tracking and managing data validation deliverables.
• Input analytical and field data, format database files, and print data summary files.
• Organize incoming data and electronic files, and manage project-specific databases for statistical analysis, risk assessments, and contamination evaluations.
• Assist in preparing and QA chemicals of potential concern selection tables under the direction of risk assessment personnel.
• Update and maintain toxicity criteria and ARARs databases.
• Assist in preparing and QA nature and extent of contamination tables, risk assessment spreadsheets, and related deliverables.
