• BROOKINGS, S.D. (AP) -- A South Dakota State University official says livestock producers should test their dams and wells for sulfates.
• Extension Field Specialist Adele Harty says recent high temperatures and low rainfall are causing increased evaporation from dams, which can boost the risk of high sulfate concentrations.
• She says high sulfate levels in water can harm or kill cattle and other livestock.
• Harty says hot, dry weather also can produce blue-green algae in water. She says livestock that drink water containing that algae will die.
• Harty says regional SDSU Extension centers can test water for farmers and ranchers.
