Two bonus features supplementing last week’s major package on estrogenic wells in Wisconsin’s karst region.

Hormonal wells found in state’s karst region; dairy farms possible source
In one of the most intensively farmed parts of America’s Dairyland, where 29 percent of the county’s private wells test unsafe due to bacteria or nitrates, residents have a new concern: estrogenic well water.
Overview: Endocrine disruptors in the environment
Scientists have learned that some chemicals may mimic or disrupt the hormones of people and wildlife, with potentially health-damaging results. They can be natural, like the estrogens produced by plants or cows, or synthetic, like birth control pills. They are known to be widespread in the nation’s waters, and to a lesser extent have turned up in groundwater. Sidebar to story on estrogenic wells in northeastern Wisconsin’s karst region.
Expert: Managing manure keeps emerging pollutants out of water
“A well-managed place is not going to get manure into the groundwater,” said Laurence Shore, a physiologist in Israel who studies the fate of hormones in the environment. With a video tour of an anaerobic digester at the two-dairy, 8,000-cow Holsum Dairies in Calumet County.
Drugs found in Lake Michigan, miles from sewage outfalls
Prescription drugs are contaminating Lake Michigan two miles from Milwaukee’s sewage outfalls, suggesting that the lake is not diluting the compounds as most researchers expected, according to new research. Republished from Environmental Health News.
20 years after fatal outbreak, Milwaukee leads on water testing
For the public officials who safeguard Milwaukee’s water, Cryptosporidium changed everything.
Study: Chemical blend lowers fish testosterone
Researchers exposed minnows to a blend of linuron, an herbicide used to control grasses and weeds, and DEHP, a plasticizer used to make medical products.
The hunt for endocrine disruptors
Minnesota researchers have found endocrine disruptors in nearly every lake they’ve tested.
Studies: Endocrine disruptors, cocaine common in Minnesota waters
Environmental experts said the discoveries in lakes, rivers and streams increase the pressure on Wisconsin to figure out what’s in its water. A key Wisconsin Department of Natural Resources official said that the state’s waters were likely also contaminated, but that the state had no money for such monitoring.
Endocrine disruptors: What can I do?
Advice from experts on how to limit your exposure and your impact on the environment.
Experts avoid sounding alarm on chemicals — but adjust their own habits
“It’s hard not to make people too worried about a lot of things,” said UW-Madison pediatric endocrinologist Ellen Connor, after running through a plethora of hypothesized health effects — genital abnormalities, tumors, lower sperm counts, diabetes, early puberty — and an equally long list of worrisome chemicals.
Tainted fish
The four groups of chemicals that trigger consumption advisories — PCBs, mercury, dioxins and PFOS (perfluorooctane sulfate) — have all been associated with endocrine disruption.
