Passed in June this year by the Natural Resources Board, the Phosphorus Rules will go into effect this month. Compliance with these rules, basically governing the numeric level of phosphorus that can be permitted to enter the water, will help to keep waters cleaner and will ultimately benefit fish and wildlife, fisheries, waterfront property owners, and recreational water users among others. Some of the negative effects of phosphorus include "toxic algae, excessive weed growth and murky water" (WDNR release).
The rules were developed over a period of time based on years of scientific research and evidence. Input from farmers, water treatment systems, manufacturers, food processors, local governments and environmental groups was also essential in their formation. There is also further work being done to help lower the cost of compliance.
