Washington, D.C.’s Potomac River Is So Polluted That Fish Change Sex (What About Our Politicians?)

90 percent of the drinking water in Washington, D.C. comes from this river, seems like an issue the politicians there themselves would want to address. Suzanne Goldenberg writes in the Guardian:
Three Eyed Fish

More than 80% of the male bass fish in Washington’s major river are now exhibiting female traits such as egg production because of a “toxic stew” of pollutants, scientists and campaigners reported yesterday.

Intersex fish probably result from drugs, such as the contraceptive pill, and other chemicals being flushed into the water and have been found right across the US.

The Potomac Conservancy, which focuses on Washington DC’s river, called for new research to determine what was causing male smallmouth bass to carry immature eggs in their testes. “We have not been able to identify one particular chemical or one particular source,” said Vicki Blazer, a fish biologist with the US geological survey. “We are still trying to get a handle on what chemicals are important.”

But she said early evidence pointed to a mix of chemicals — commonly used at home as well as those used in large-scale farming operations — causing the deformities. The suspect chemicals mimic natural hormones and disrupt the endocrine system, with young fish being particularly susceptible.

    Hooray for combined sewage & storm water systems, runoff, improper disposal of chemicals/medications, and industrial dumping!

    Hey Disinfo, are you going to include topics like this in the upcoming film about how evil bottled water is? The average water filter on the market does nothing to address issues such as this, and yet you encourage us to ditch our bottled spring water – maybe try reading some of your own posts!

      Or instead of looking through the big report, just look at the key differences in testing requirements:

      Maybe Dean you should not linking issues that have nothing to do with each other. You really don't find it alarming that male fish are producing eggs???

      How about Dean, you not link issues that aren't related. You really don't find it alarming that male fish are producing eggs? Was this happening when Washington crossed the Potomac?

    we need not worry what we dump into our water, or how we damage the land.
    only about CO2 emissions.

      I hope you're being facetious. If not:

      Water and land pollution not worth addressing? Tell that to children who's school is shut down because of toxic water. Tell that to a 2 year Cancer patient (now deceased) who discovered the water he was using at home for washing clothes, dishes and his own body had carginogens in it. You're sadly delusional if you think pollution all around ought not to be a concern.

        you need new batteries in your sarcasm meter. 😛

    Well, it certainly explains why the DNC collectively grew a vadge instead of balls.
