Key Assumptions in Groundwater Testing Normality, stationarity, data independence RCRA Groundwater Statistical Framework Monitoring stages Balancing statistical errors Statistically significant increases (SSI) Power Curves Importance of Background Establishing and implementing background Strategies for Compliance Monitoring Testing under unstable conditions Comparisons to background data

Statistical Design in Detection Monitoring Multiple comparisons, site-wide false positive rates Parametric vs. Non-parametric tests Interwell vs. Intrawell tests Incorporating Retesting What to do with Difficult Data Outliers, non-detects Spatial variation, temporal correlation Recommended statistical methods Prediction limits, control charts Trend tests Confidence intervals

He has over 20 years of experience in teaching and consulting to USEPA, DoD, DoE, the US Air Force, and private environmental and medical firms. Dr. Cameron is the primary author of both USEPA's Interim Final Guidance document for the statistical analysis of groundwater monitoring data (1992) and the recently published major update to this guidance entitled the Unified Guidance (2009). He has designed training courses on the statistical analysis of groundwater monitoring data and presented to regulators, consultants, and environmental professionals around the country. He also filmed a commercial videotape training series on groundwater data analysis. More recently. Dr. Cameron developed a no-cost, publicly-available, geostatistical and statistical-based software tool (GTS v1.0) for the US Air Force and DoD to optimize sampling frequencies and locations at sites undergoing long-term ground-water monitoring (LTM).
