Fmr. Ag/Chem site with gypsum stacks and cooling ponds. Groundwater monitoring for COCs ceased in 2020. The cooling pond tested pH values are sometimes lower than the 6.5 standard in IAC 567.61. It was determined the cooling pond pH is outside the purview of Con Sites and should be handled by Water Quality, NPDES, or Army Corps. Annual inspections of the stack continue with EC recommended to move towards closure.
