Dozens of Cook County residents stopped by the Metropolitan Water Reclamation District of Greater Chicago’s (MWRD’s) North Side, Stickney and Calumet Water Reclamation Plants recently to drop off unwanted or expired medications. The MWRD served as a collection site for the U.S. Drug Enforcement Agency’s (U.S. DEA’s) National Take Back Day and collected enough pharmaceuticals to fill 10 – 30 pound bags which will be properly disposed of in an environmentally-friendly manner.
