Applied Groundwater Statistics

An Introductory Course in RCRA Statistics for Environmental Professionals. 14.5 Professional Development Hours.

Upcoming Workshop schedule:

September 20-21, 2023 Online

Course Description:

This course is designed to provide a fundamental understanding of groundwater statistics necessary to ensure a facility's compliance with federal and state regulations.

The instructors focus on teaching the underlying concepts and application of environmental statistics.  They utilize examples and case studies to bring this dry subject to life.  No derivations required.

Sanitas software (formerly known as GSAS) is introduced and used in conjunction with lectures.  Participants will work through exercises solving a number of scenarios often encountered in groundwater monitoring programs.  They will learn to identify and justify the most appropriate statistical analyses for a site's specific characteristics.

Ample time will be provided to discuss participants' individual statistical analysis issues.  This course creates an environment where consultants, owner/operators and regulators work as a team to solve real world problems. 

Course content has recently been updated to incorporate the latest recommendations from the EPA's Unified Guidance.

Who Should Attend:

This is an introductory course in RCRA statistics that would be useful to:

  • Groundwater Specialists
  • Environmental Engineers
  • Regulatory Professionals
  • Solid and Hazardous Waste Environmental Professionals
  • Compliance Managers
  • Others Involved with RCRA Statistics


Kirk Cameron, Ph.D., President, MacStat Consulting, Ltd.

Dr. Cameron has been closely involved with the statistical analysis of groundwater and other environmental media since 1990. He has conducted training sessions with EPA, State, and industry personnel who deal with RCRA statistical issues across the country since 1992. He received his PhD in Statistics from Stanford University.

Dr. Cameron wrote the 1992 Addendum to the Interim Final Guidance document on the statistical analysis of groundwater monitoring data, a draft guidance document for the practical geostatistical sampling of soils data, and the March, 2009, Statistical Analysis of Groundwater Monitoring Data at RCRA Facilities Unified Guidance. He also provided expert design and review of the groundwater Information and Tracking System (GRITS) statistical software package tailored for the analysis of ground-water data at RCRA sites. He has also taught seminars at the Waste Testing and Quality Assurance Symposia and presented at the Virginia and Maryland State Landfill Seminars.

Kristina L. Rayner, B.S., Project Manager, Sanitas Technologies
