The discussion about the environment in Wisconsin varies by community, or so it seems. Some parts of the state, particularly northeast Wisconsin, have a more active discussion because residents there perceive greater environmental risks, particularly to their water supplies.
The Wisconsin Center for Investigative Journalism has a series that follows much of this discussion, online at Project: Water Watch Wisconsin.
They have three components to their series: Failure at the Faucet (about private well water), Drying Up (about the influence of high-capacity wells on the water supply), and Murky Waters (about threats to the lakes near Madison).
The whole series is well worth reading, and following as new installments become available.
