The objective of the Feasibility Study (FS) is to evaluate clean-up options and technologies to address remaining contamination that must be remediated within the Nevada Environmental Response Trust (NERT) Remedial Investigation (RI) Study Area. This analysis occurs prior to the selection of a final remedy to address contamination that must be remediated originating from the NERT Site within the three OUs. Each remedial action alternative applicable to the contaminants associated with former manufacturing operations at the NERT Site is compared against a number of performance goals called Remedial Action Objectives and Nevada and federal environmental regulations.

As part of the FS process, the Trust is conducting a number of treatability and pilot studies to assess various treatment technologies to be considered in the FS evaluation and determine the best cleanup method(s) for the final remedy. Each of NERT’s treatability and pilot studies is outlined below.

Findings from the RI, running scenarios using NERT’s groundwater model, and the results of the various treatability and pilot studies will be used in the FS evaluations. Performance of the FS for OU-1 and OU-2 began in 2023 in accordance with the  Feasibility Study Work Plan for OU-1 and OU-2, Revision 1 (NDEP approved on October 20, 2023). After review of comments from NDEP on the RI Report for OU-3, NERT will submit the Integrated Feasibility Study Work Plan that will merge the FS for OU-1 and OU-2 with the FS for OU-3 and the ECAs in OU-1 into one FS Report. Currently, the FS Report is anticipated to be submitted to NDEP in 2029.
