Cattle feed lotLast spring, the Wisconsin Department of Natural Resources held a public hearing to consider increasing the nitrate limit for a cattle farm in Adams County. Before the hearing, the Sierra Club Foundation – John Muir Chapter rallied supporters to oppose the new limit. They wrote newsletter articles, and encouraged people to send comments to the DNR and to testify at the public hearing. As a result of this grassroots activism, the increased pollution limit was denied—and the public health impact on drinking water was avoided.
