USGS Studies Pharmaceuticals in our Streams

CA: Santa Barbara, Medicines

The USGS just released a study of 59 streams in the Southeastern United States ranging from Georgia to Virginia. Alarmingly, the study showed that every single one of these streams tested positive for pollution by pharmaceutical compounds.

These compounds have a wide variety of negative impacts on the entire aquatic ecosystem including altering the base of the food web, affecting neurotransmitters for many aquatic insects, and affecting the reproductive health of fish.

One of the main causes of this pollution is homeowners’ tendency to flush unused medications down the toilet. There are alternatives to this harmful habit.

There are many community based drug “take-back” programs you may use to dispose of your medicine – call your local government to find out more information. Otherwise disposing your medicine in the trash is the best option. Take action today to prevent your medicine from polluting local waterways.

Share this information with your friends, and let us know how you help keep your streams clean.
