another CNN article about drugs in the water

Pharmaceuticals in the water are being blamed for severe reproductive problems in many types of fish: The endangered razorback sucker and male fathead minnow have been found with lower sperm counts and damaged sperm; some walleyes and male carp have become what are called feminized fish, producing egg yolk proteins typically made only by females.
Meanwhile, female fish have developed male genital organs. Also, there are skewed sex ratios in some aquatic populations, and sexually abnormal bass that produce cells for both sperm and eggs.
There are problems with other wildlife as well: kidney failure in vultures, impaired reproduction in mussels, inhibited growth in algae.
"We have no reason to think that this is a unique situation," says Erik Orsak, an environmental contaminants specialist with the U.S. Fish and Wildlife Service, pulling off rubber gloves splattered with fish blood at Lake Mead. "We find pretty much anywhere we look, these compounds are ubiquitous."
For example:
• In a broad study still under way, fish collected in waterways near or in Chicago, Illinois; West Chester, Pennsylvania; Orlando, Florida; Dallas, Texas; and Phoenix, Arizona, have tested positive for an array of pharmaceuticals -- analgesics, antibiotics, antidepressants, antihistamines, anti-hypertension drugs and anti-seizure medications.
