In addition to serving as Cadmus’ technical lead for hydraulic fracturing work, Dr. Koplos provides oversight for the Six-Year Review of National Primary Drinking Water Regulations (NPDWR) and Geologic Sequestration Rule Implementation Guidance development and manages technical research on injection wells and wastewater management in support of EPA’s current national assessment of the potential impacts to drinking water resources related to oil and gas operations that conduct hydraulic fracturing.

Dr. Koplos has made presentations at workshops and conferences given by EPA, the Ground Water Protection Council, the U.S. Department of Energy, the Society of Petroleum Engineers, and the International Energy Agency’s Greenhouse Gas Research Programme.
