Concerns grow about hormone-disrupting chemicals in Wisconsin water
Endocrine disruptors have been called a “global threat” to people and wildlife, but Wisconsin is lagging behind Minnesota in testing its waters for them.
New studies measure air, water impacts of frac sand mines
Competing studies are under way to assess air pollution from Wisconsin’s frac sand industry, and the author of one said current state law isn’t protecting people well enough. A separate study, meanwhile, will examine the impact of frac sand mines on water.
Frac sand industry faces DNR violations, warnings
Nearly a fifth of Wisconsin’s 70 active frac sand mines and processing plants were cited for environmental violations last year, as the industry continued to expand at a rapid clip.
