Mr. Cramer is the Environmental Technologies Manager at Burns & McDonnell in their Brea, CA office. He has more than 30 years experience in the environmental field with a focus on developing geology-based groundwater Conceptual Site Models (CSMs) for complex sites to successfully design and implement remediation strategies. He began his career in the petroleum industry and pioneered the application of sequence stratigraphy to groundwater remediation projects in the early 1990s. He later developed the practice of Environmental Sequence Stratigraphy (or ESS), a geology-based groundwater remediation method that is now the standard for the Air Force Civil Engineer Center (AFCEC) for developing CSMs and is considered an emerging best practice by the United States Environmental Protection Agency (USEPA). Mr. Cramer is a California licensed Professional Geologist (PG) and holds a MS degree in geology from University of California, Davis and a BS degree in geology from University of the Pacific, Stockton, CA.
