There is growing concern about the presence of pharmaceuticals in aquatic habitats and drinking water. “Pharmaceuticals enter the water supply through human excretion and when residents flush unused or expired medications down the toilet,” says Deborah Comella, executive director of the Coalition for a Drug-Free Southwest Florida.

With support from the United Way of Lee, Hendry, and Glades Counties, Operation Medicine Cabinet–Lee County educates citizens on the importance of proper storage and disposal of prescription medications—not only to prevent drug misuse, but also to keep our waterways clean and safe. Many people are unaware that a significant percentage of those abusing prescription opioids obtain them from their own homes or the homes of family and friends.

“We remind residents to avoid flushing medications or pouring them down bathroom or kitchen drains, as these substances eventually end up in our rivers, lakes, and drinking water,” says Comella. “This also poses a serious risk to wildlife and contributes to the development of antibiotic-resistant bacteria.”

Local law enforcement agencies have specialized lockboxes for collecting discarded medications. Residents who wish to safely dispose of their medications can contact their nearest law enforcement agency. Additionally, the U.S. Drug Enforcement Agency and local law enforcement host “Take Back Days” twice each year—in April and October—for the safe disposal of unused medications.

Drug-Free Lee coordinates a Deterra Bag distribution event, which provides an in-home medication disposal system. The activated carbon in DeTerra bags binds to the active ingredients in prescription and over-the-counter medications, rendering them inert and safe for disposal in the regular trash. The bags have been lab-tested and proven to deactivate medications—whether in the form of pills, liquids, creams, films, or patches—permanently and irreversibly. They are also effective at neutralizing dangerous narcotics such as opioids and psychoactive drugs like ketamine.

Pharmaceuticals in Seafood

A three-year study conducted by Florida International University (FIU) and Bonefish & Tarpon Trust (BTT) found alarming levels of pharmaceutical contaminants in the blood and tissues of bonefish in Florida waters. These included antidepressants, antibiotics, prostate treatments and painkillers—raising concerns about broader contamination in the food chain. Researchers also discovered pharmaceuticals in the bonefish’s prey—crabs, shrimp, and smaller fish—indicating that multiple parts of Florida’s marine ecosystem, and not just the bonefish fishery, are contaminated. This poses a serious threat to both fisheries and human health.

Allini Water Filters

Naples-based Allini Water Filters stresses the importance of home filtration systems, as current EPA standards haven’t regulated any new industrial contaminants in over 20 years. They note that economic and political factors often influence safety standards more than health data.

Allini’s website points out that the frequent discrepancies between the guidelines for industrial contaminants and the enforceable standards suggest that these standards are not solely based on health concerns.

Operation Medicine Cabinet is also active in Collier County, with permanent drop-off sites listed at DrugFreeCollier.org. Since 2014, over 40,000 pounds of medications have been collected.
