EXPERTISE

GSI develops and applies natural attenuation tools; applies multiple lines of evidence to develop the best case for demonstrating natural attenuation; and provides state-of-the-art natural attenuation expertise for industrial and military clients.

REPRESENTATIVE EXPERIENCE

Air Force Initiative: Conducted $2.5 million U.S. Air Force RNA research and development program consisting of field analysis at a number of Air Force sites througout the U.S.

BIOSCREEN: Developed the BIOSCREEN natural attenuation model for U.S. Air Force. BIOSCREEN, designed for fuel sites, is the U.S. EPA's most frequently distributed model in history from their modeling web page, with 6,000+ downloads.

BIOCHLOR: Developed the BIOCHLOR natural attenuation model for U.S. Air Force. BIOCHLOR, designed for chlorinated solvent sites, is the EPA's most frequently distributed model since it was released in January 2000.

ASTM Committee: Served on ASTM RNA Committee and developed nationwide training curriculum for ASTM training program. Developed the RNA Tool Kit, a software package for analyzing and interpreting RNA data using the ASTM methodology.

Book: Co-authored Natural Attenuation of Fuels and Chlorinated Solvents, published by John Wiley & Sons in 1999.

Studies: Applied RNA at petroleum release sites, gas stations, gas plants, chlorinated solvent sites, and chemical plants sites, including one site where an RNA demonstration for a 1500 ft long plume replaced a planned $2.5 million pump-and-treat system.
