The state has appointed a task force to investigate ways to minimize the risk of manure runoff contamination in streams and water sources.
During the past year, the state Department of Natural Resources reported 32 manure runoffs in Wisconsin.
The nitrogen and phosphorous contained in manure can contaminate streams and drinking water supplies through runoff.
Environmental and agricultural officials say careless application of manure and shortages in storage space cause runoffs. Manure applied to frozen ground is washed into nearby streams by rain.
D-N-R Secretary Scott Hassett says it's time for a comprehensive approach to fix the problem.
The D-N-R and the department of Agriculture, Trade and Consumer Protection appointed the task force. Its study should be done in December.
