NTCRA Building Demolition Complete

Total Groundwater Processed

Through mid-June, 2019, approximately 1.35 million gallons of groundwater have been processed through the Permanent Groundwater Treatment System (Final Treatment System), which has been operational since April 2, 2019.

Previously, approximately 17 million gallons of groundwater were processed through the Temporary Groundwater Treatment System (TGTS) to maintain hydraulic capture of the plume. The TGTS operated from May 23, 2017 until the Final Treatment System was operational.

The work under the Building NTCRA is now substantially complete with all demolition and off-site disposal of building debris finished. Placement of a liner cover over the demolished building sites to prevent rainwater infiltration prior to the start of the final remedial action is also complete, as shown in the August 2016 aerial photo. An updated photo log for July and August 2016 demolition activities can be found here. More photos on building demolition can be found on NTCRA Progress.
