The Grass is Always Cleaner (Wetlands and Estrogen)

Both humans and animals secrete hormones, which eventually wind up in wastewater. Traditional sewage treatment plants are unable to remove the hormones, and livestock effluent is rarely treated. Researchers in 2004 tested streams in 30 states and found estrogen in 80 percent of the waterways. 

But recently, scientists led by Nancy Shappell of the federal Agricultural Research Service found that artificial wetlands at a swine facility in Greensboro, North Carolina, removed 83 percent to 93 percent of estradiol—a form of estrogen—from wastewater. They reported their findings on December 6 in an online edition of the journal Environmental Science and Technology.

Hmmm, so basically we have to recreate part of the environment that has been getting stomped out?  It is nice to see that they are working on ways to address the contamination of waterways by hormones.
