HiPOx Case Study: Nebraska Ordnance Plant, Mead, NE

By APTwater, Inc.

APTwater, Inc. (APTwater) installed a high capacity HiPOx® system for the remediation of TCE-contaminated groundwater at a former military installation near Mead, Nebraska. The system treats 575 gpm of groundwater with TCE concentrations as high as 5,800 ppb. HiPOx technology was selected based on its up to 71% lower annual operating cost versus the existing air-stripping and vapor-phase carbon treatment system. The HiPOx system achieves >99.8% removal of TCE before effluent is sent to the existing carbon system for final polishing. Treated water from the remediation system meets all public health requirements and is pumped over 1 mile away for irrigation and surface water discharge.
