Contact Information

Cynthia J. Paul, Environmental Scientist

Phone: 580-436-8556

Ms. Paul is an Environmental Scientist in GWERD’s Subsurface Remediation Branch. She holds a B.S. in Biology from East Central University, Ada, Oklahoma, and an M.S. in Environmental Science from the University of Oklahoma in Norman, Oklahoma. Her research area is monitored natural attenuation.

Ms. Paul’s recent research has been evaluating a new passive diffusion sampler at underground storage tank sites for use in calibrating the Johnson and Ettinger Model for vapor intrusion assessment. Field sites include A1 Movers in Madison, Wisconsin; Hal’s Chevron in Green River, Utah; and Lemoore Naval Air Station in Lemoore, California. Additional vapor intrusion research has been conducted at the Raymark Superfund site in Stratford, Connecticut.

Ms. Paul’s other research area is permeable reactive barriers for in situ chromate remediation at the U.S. Coast Guard Support Center, Elizabeth City, North Carolina. Ms. Paul has also participated in extensive field research that led to the development of low-flow sampling methodology for groundwater. She has also been involved in arsenic research at the Industri-Plex Superfund Site in Woburn, Massachusetts, and the Asarco site in Helena, Montana.

Ms. Paul is the work assignment manager for the onsite contract for inorganic analysis for subsurface protection and remediation and serves on GWERD’S Environment Management System Team.
