As a Pollutant
Because humans and animals often do not fully metabolize pharmaceuticals in their body, they can excrete drugs or their breakdown products, which may the enter the environment.[8]
In Sewage Sludge
Doxycycline has been found in sewage sludge. In the Targeted National Sewage Sludge Survey, a 2009 test of 84 samples of sewage sludge from around the U.S., the EPA found doxycycline in 76 samples (90%) in concentrations ranging from 50.8 to 5,090 parts per billion.[9] There are no federal regulations governing how much of this drug may be present in sewage sludge applied to land as fertilizer.
In Drinking Water
An Associated Press investigation found that, of 62 metropolitan areas in the U.S., only 28 tested for pharmaceuticals, and 24 found pharmaceuticals in the drinking water when they tested it.[10] Of those tested, Philadelphia tested positive for doxycycline (as well as 55 other drugs).[11]
