Pharmaceuticals Impact in Waterways
Pennsylvania Fish and Boat Commission (PFBC) Executive Director John
Arway described to the PA Senate Environmental Resources and Energy Committee how fish and aquatic life are impacted by complex
mixtures of pharmaceuticals and other compounds released into waste
streams and found in runoff from landscapes and urged the public to
properly dispose of expired and unused medications.
“Research
beginning in 1999 first showed that chemicals found in medications were
being absorbed by fish and were contributing factors to a number of
fish health problems,” Arway said. “Perhaps the most troubling condition
is intersex fish. This is where male fish develop female egg cells in
their testis.”
Arway
noted that the U.S. Geological Survey Fish Health Laboratory reported
in 2013 that approximately 50 percent of male bass in the Delaware River
had intersex condition, 10 percent in the Ohio River drainage were
affected, and up to 100 percent of the males sampled in the Susquehanna
River were found to have intersex. More recent samples in the
Susquehanna confirm that 90–100 percent of male Smallmouth Bass have
intersex condition and that this condition is more severe than found in
other drainages.
“How
can we as a society make progress in reducing pharmaceuticals from
getting into our lakes, streams and rivers?” Arway said. “Removing
unused pharmaceuticals from homes and providing proper disposal
alternatives is an important first step in reducing the amount of
compounds getting into lakes, rivers and streams. Improving wastewater
treatment processes to provide more effective removal of medications is
another effective solution.”
Last
month, the PFBC announced that it had partnered with Geisinger Health
System to install a drug take-back box in the agency’s Harrisburg
headquarters to provide a way for citizens to safely dispose of unused
medications and help improve the health of the Susquehanna River and its
Smallmouth Bass.
