Municipal waste water treatment plants are not designed to remove the complex compounds in both over-the-counter and prescription medication. As a result, trace amounts are being detected in our streams, rivers, and clean drinking water. Fortunately, the Fishers and Westfield Police Departments, as well as the Hamilton County Sheriff’s Department, all provide a medication dropbox in their lobbies for residents to use during open office hours. Please contact the location nearest to you for more detailed information on their collection program.
