Emerging Contaminants in Our Aquatic Environments

Food, plastics, and in fact, most of what was landfilled could have been recycled or composted. Of particular concern is the more than four percent of waste classified as ‘other,’ which includes pharmaceuticals and personal-care products.


A recent article, “Pharmaceuticals and Other Chemicals Common in Landfill Waste,” brings light to the fact that rain water filtering through a landfill picks up chemicals and exits the landfill as ‘leachate.’ While treatment of the leachate and NPDES permitting is required, questions about how these chemicals affect the environment still remain.


The USGS sampled 19 landfill leachates before treatment and found 129 different pharmaceutical (prescription and non-prescription), household, and industrial chemicals. The three chemicals detected in 95 percent of the samples were bisphenol A (used in plastics, thermal paper, and epoxy resins; 4 parts per million), DEET (insect repellent; 250 parts per billion), and cotinine (transformation product of nicotine; 50 parts per billion).


In order to help address some of these questions and many more, ISTC is partnering with Illinois-Indiana Sea Grant (IISG) to host the “Emerging Contaminants in the Aquatic Environment Conference” on May 31 and June 1, 2017, in Champaign, IL. Conference registration will begin in mid-February. Topics will include research, policy, management, outreach, and education concerning emerging contaminant detection, fate, transport, remediation, prevention, or related areas.
