Traci Barkley, Water Resources Scientist
Traci leads our program to protect Illinois waters from coal related pollution and damage to waterways. Illinois’ history as a coal mining state has led to a too-cozy relationship between the industry, lawmakers, and regulators. Traci is working to bring accountability to coal mining and coal ash disposal in Illinois, so that the industry is held to the same water pollution control standards as other industries.
Background: When Traci first joined PRN in 2005 she worked to reduce pollution entering our rivers and streams by ensuring that municipalities, mining operations, and industries follow Clean Water Act regulations that include specific limits on the amount of pollution allowed to be discharged into a river or stream. Prior to PRN, Traci worked for IEPA where she was involved in water quality monitoring; provided technical assistance to the public, local watershed groups, and state agencies; and was involved in statewide discussions related to water quality standards and criteria, NPDES permits, and TMDL development. She also coordinated River Watch volunteers for the Illinois EcoWatch program, a citizen monitoring program that tracks ecological trends in Illinois. Traci is also a former PRN volunteer.
Education: B.S. in Ecology and M.S. in Natural Resources and Environmental Sciences.

Elliot Brinkman, Water Resources Specialist – Habitat Conservation
Area of Focus: Habitat and Restoration
Elliot is advancing our work in riverside habitat restoration and conservation. Even if we were able to remove all pollution from Illinois’ rivers, they would not be healthy without native plant and animal communities alongside them. Our initial efforts have supported public and private landowners in cooperative conservation planning efforts along the Vermilion and Mississippi Rivers.
Background: Elliot Brinkman joined PRN in April, 2011. Prior to joining PRN, Elliot worked as a research assistant on a USDA-CSREES funded Watershed Health Integrated Research (WHIR) project in the lower Kaskaskia River region in Illinois. He was responsible for collecting and analyzing social data from several communities within the study area, and assessing capacity for watershed conservation. Elliot has also worked at Redwood National and State Parks as an environmental educator.
Education: B.S. in Forestry, with an emphasis on Outdoor Recreation Resource Management and an M.S. in Forestry, specializing in Human Dimensions of Natural Resource Management

Robert Hirschfeld, Water Policy Specialist
Areas of Focus: Asian carp, invasive species, water law
Robert leads our Stop Asian Carp campaign. The high visibility of this issue provides the opportunity to address a long-standing problem: the man-made connection between the Mississippi River and the Great Lakes in Chicago’s canal system provides a two-way superhighway for invasive plants, fish, and parasites to be transferred from one system to another. He is also working to fix our outdated water laws in Illinois.
Background: Robert Hirschfeld joined PRN in March 2011. Before joining the professional staff, Robert was a legal intern for PRN, working on Clean Water Act compliance and enforcement. Robert is also an editor of the Champaign-Urbana online magazine Smile Politely and a working musician.
