Noticed any strange changes in yourself lately?
Abnormally developed fish, possessing both male and female characteristics, have been discovered in the Potomac River in the District and in tributaries across the region, federal scientists say — raising alarms that the river is tainted by pollution that drives hormone systems haywire.
The fish, smallmouth and largemouth bass, are naturally males but for some reason are developing immature eggs inside their sex organs. Their discovery at such widely spread sites, including one just upstream from the Woodrow Wilson Bridge, seems to show that the Potomac’s problem with “intersex” fish extends far beyond the West Virginia stream where they were first found in 2003.
The cause of the abnormalities is unknown, but scientists suspect a class of waterborne contaminants that can confuse animals’ growth and reproductive systems. These pollutants are poorly understood, however, leaving many observers with questions about what the problems in fish mean for the Potomac and the millions of people who take their tap water from it.
“I don’t know, and I don’t think anybody knows, the answer to that question right now: Is the effect in the fish transferable to humans?” said Thomas Jacobus, general manager of the Washington Aqueduct, which processes Potomac water to provide drinking water for residents of the District, Arlington County and Falls Church
