Wisconsin’s Department of Natural Resources says it doesn’t yet know what 400-thousand-gallons of waste from a frac sand mine will mean for the Trempealeau River.
DNR is blaming a faulty pump at the Wisconsin Proppants Hixton in Jackson County for the spill last weekend. Investigators say there’s no evidence of a fish kill or other contamination in the river. Test results on the leaked waste water are expected in a few weeks.
