Pharmaceutical Water Sampling

These are reports by the IEPA, in collaboration with the Illinois Department of Public Health, on a pilot study that included sampling of drinking water supplies for the presence of chemicals found in many common pharmaceutical and personal care products. The initial sampling and analysis included Chicago, Elgin, Aurora, Rock Island and East St. Louis. A companion document contains detailed sampling results for each location. While the pilot study found the levels of the chemicals pose no known health risk at this time, it concluded that further analysis was needed along with efforts to potentially reduce the quantities of these chemicals getting into rivers and lakes.
