I have 12 years of experience and specialize in the field of environmental hydrology with specific knowledge in the areas of transport and fate of petroleum hydrocarbons, including MTBE, chlorinated solvents and petroleum hydrocarbon. I have published on such topics as remediation of polluted soil and groundwater with solvents and MTBE, transport and fate of petroleum contaminants and stormwater runoff contaminats. I have testified on MTBE pollutions of drinking water wells, possible impact of BETX on surface water and PAH contamination of soils.
