Water Quality > Pharmaceuticals


Partnered with Cornell University since 2015, Riverkeeper has documented dozens of compounds associated with pharmaceuticals, personal care products, pesticides and industrial compounds in the Hudson River Watershed. Ninety pharmaceutical compounds or their breakdown products have been detected in surveys to date. Pharmaceuticals are found in higher number and at higher concentrations near the outfalls of sewage treatment plants, indicating that the pharmaceuticals we excrete, and the unused pharmaceuticals flushed down the drain, are entering our waterways.

While each compound is detected at low levels, it is unknown what effects the mix of “micropollutants” might have on the ecosystem or human health.This research is helping to fill a global knowledge gap. As the Cary Institute has reported, research on the ecological effects of pharmaceuticals, pesticides and industrial chemicals is “severely lacking” despite an explosion of global manufacture and use, particularly since 1970.

To keep unused pharmaceuticals out of our water – and out of the hands of those who might abuse them – Riverkeeper advocates for the safe, responsible disposal of pharmaceuticals.

National Prescription Drug Take-Back Days are held in April and October, and many counties and municipalities host additional take-back days throughout the year. Many law enforcement agencies have drop-boxes where people can safely dispose of pharmaceuticals, often 24-7.

Rockland County has approved a first for the East Coast, a county law requiring retail pharmacies with three or more locations to take back and safely dispose of pharmaceuticals. We hope other counties will follow.


The next National Take-Back Day is April 28, 2018. Search takebackday.dea.gov to find a collection point near you. There are typically dozens in the Hudson River Watershed.
