Biography

Ms. Susan C. Mravik is a Soil Scientist in GWERD's Subsurface Remediation Branch. She received a M.S. in Agronomy from the University of Illinois in 1986 and a B.S. in Agronomy from the University of Wisconsin-River Falls in 1980. After receiving her B.S. she worked at the Swiss Federal Institute of Technology in Zürich, Switzerland as a soils technician where she assisted with a field project to characterize the major soil types found in Switzerland. After returning to the U.S. she worked for the USDA-Soil Conservation Service where she created and implemented conservation plans for farmers and landowners.

After receiving her M.S. she worked for the Illinois State Geological Survey as an assistant geochemist. She worked on a project concerning the interactions of hazardous wastes with geological formations in deep-well systems and assisted with a joint project with the Illinois State Water Survey to make recommendations for a statewide survey of pesticides in rural, private water wells in Illinois.

Since 1988 Ms. Mravik has been employed by the USEPA- NRMRL-GWERD and her initial research investigated the effect of residually-saturated nonaqueous phase liquids (NAPL) on the transport of neutral organic compounds. She has worked with projects concerning the effect of co-solvents on the transport of PCBs and the mobilization and dissolution of NAPLs. She worked for 10 months with Dr. Göran Bengtsson at the University of Lund in Sweden on a project concerning the sorption of ionizable organics on pure clay minerals and humic substances.

Currently Ms. Mravik is involved in research concerning new source removal and treatment technologies, including surfactant, co-solvent and enhanced biotreatment processes for DNAPL remediation. She has been evaluating data from a former dry-cleaner facility that was remediated with an ethanol co-solvent flush and is monitoring ground water data for evidence of in situ reductive dechlorination of PCE.
