Dual-sex fish in Potomac raise safety questions for D-C-area water system
WASHINGTON Scientists say more dual-sex fish are swimming in the Potomac River -- and the cause may be pollution.
The fish with both male and female characteristics have been discovered in the rivers and streams around the nation's capital. And that's spawning questions about the impact of contaminants on the (m) millions who drink the tap water.
The general manager of the water-filtering Washington Aqueduct says he doesn't think anybody has the answer right now. But he says there's no evidence that tap water from the Potomac is unsafe.
Scientists say humans should be less susceptible to pollutants, anyway, because they have larger bodies and different hormone systems. And unlike fish, they aren't constantly immersed in water.
