Statistical modeling has become a very popular tool for evaluating sampling uncertainty and developing site characterization programs. More and more, regulatory agencies are requiring the use of statistical procedures in the development of the site characterization program as well as the remediation phase of the project. InControl Technologies is at the forefront of statistical modeling of environmental contamination in soil and groundwater. We have been active on a number of major Superfund sites that required the development of comprehensive statistically based sampling and analysis plans, remedial action confirmation programs, and geostatistical modeling and uncertainty analysis of various remedial action programs. We have developed an extensive library of specialized routines and computer models to help conduct these efforts. We have completed many projects that have incorporated a number of different statistical programs including:
• Statistically-based sampling and analysis plans;
• Geostatistical analysis of chemical data in soil and groundwater;
• RCRA Statistical Groundwater Compliance and Detection Monitoring Programs;
• Wastewater and air permit discharge criteria;
• Development of statistically-based permit standards; and
• Statistical confirmation sampling and closure criteria.
These statistical tools can be incorporated into your site characterization program to ensure that the site has been delineated or has achieved applicable cleanup criteria to a known degree of confidence, thereby giving you a better understanding of the uncertainty associated with any decisions made with your data.
