AI Summary

Environmental groups in Iowa have taken legal action against the state's Department of Natural Resources for issuing permits that enable the disposal of hazardous materials at a coal ash landfill. The landfill in question is located in Ottumwa and contains waste from a nearby coal-burning power plant co-owned by Alliant Energy and MidAmerican Energy. The groups are concerned that toxic discharge from the plant is contaminating Iowa's groundwater. The lawsuit aims to halt the disposal practices at the landfill, which the groups argue pose a significant environmental risk.
