What is nitrate?

Nitrate is a compound naturally found in plants and in vegetables and can be found in groundwater, depending on how much fertilizer and manure is applied to fields.

Going organic: One farmer’s fight against contaminants in the groundwater

In the early 1990s, Jim Goodman and his wife began to worry about how the chemicals they were using on the farm might affect their children. The fourth-generation Wisconsin farmer decided to make the shift away from conventional farming at his Sauk County operation. Now certified organic, the farm includes 120 head of cattle on pasture, including 45 milk cows, and 300 acres of crops.

Nitrate in water widespread, current rules no match for it

Levels of nitrate, one of the Wisconsin’s top drinking water contaminants, are increasing. Nitrate comes primarily from fertilizers, including manure, and puts infants and expectant mothers particularly at risk. A projected 94,000 households are drinking private well water with unsafe levels of nitrate. And many of them don’t even know it since few private well owners conduct regular testing.

Big farms, frac sand mines could feel force of judge’s groundwater ruling

Two weeks ago, Administrative Law Judge Jeffrey Boldt approved the state Department of Natural Resources’ issuance of permits for a large and controversial dairy farm in Central Wisconsin. But he also reduced the amount of water the farm could pump from proposed high-capacity wells and required the DNR to consider the impact of the withdrawals in conjunction with other, nearby wells — a concept known as cumulative impacts.
