New Legislative Request Regarding Contaminants of Emerging Concern in Illinois Wastewater Effluent

The Illinois governor recently signed House Bill IL-HB5741 that amends the University of Illinois Scientific Surveys Act. The new section 21 asks the Prairie Research Institute (PRI), which was established under the Scientific Surveys Act in 2008, to conduct a scientific literature review of chemicals identified in wastewater treatment plant effluents that are recognized as contaminants of emerging concern. It also requests that PRI compile a listing of the specific actions recommended by various state and federal agencies to address the environmental or public health concerns associated with the chemicals. PRI will provide its impartial report to the General Assembly by June 30, 2020.

Because of its long history of pollution prevention expertise, the Illinois Sustainable Technology Center (ISTC), a division of the Prairie Research Institute, will take the lead on this new effort. ISTC researchers have studied a variety of inorganic and organic environmental contaminants as well as developed methods for waste and pollution prevention. Recently much of their water quality research and public engagement activities have focused on chemicals of emerging concern in wastewater, surface water, and groundwater. ISTC staff members Nancy Holm, Laura Barnes, and Elizabeth Meschewski will be compiling the report.

Although the law requests a literature review of contaminants of emerging concern associated with wastewater treatment plant effluent, these contaminants also enter the environment from other sources. These include non-point sources, such as agricultural fields, and other point sources, such as large animal feeding operations, septic systems, and industrial operations.
