Temporary Groundwater Treatment System Operational

Since May 23, 2017, a temporary groundwater treatment system has been operating as part of the NMI Superfund Site Non-Time-Critical Removal Action (NTCRA) for Groundwater. This treatment system is designed to extract groundwater and create a zone of hydraulic containment to minimize movement of 1,4-dioxane. This temporary system has been implemented to operate during the design phase of the permanent treatment system. Hydraulic monitoring and analytical results indicate that performance objectives for the temporary treatment system are being achieved, as supported by the data included in the December 2017 Demonstration of Compliance Report, submitted to EPA on January 10, 2018.
