During excavation of the uranium mill tailings pile in Moab, Utah. Free pore fluids were encountered with a pH as low as 2.5. The fluids began flowing from intercepted wick drains that were installed in 1998. Fluids were allowed to flow to temporary ponds prior to pumping to a 1.6 ha (4 ac) evaporation pond located on top of the tailings pile. Special precautions were taken to blend the low pH water to an acceptable level for spreading on top of the tailings pile to evaporate.
