Soil and Groundwater Remediation Project

Company Performed Work:

AEM Consulting, LLC

Work Description:

 The primary scope of work was to provide process engineering support to the operation of existing groundwater remediation facilities and to evaluate process options for new facilities.  The work was performed as staff augmentation and no technical submittals from AEM  Consulting, LLC were required.

Major specific tasks were:

  • Evaluate process design options for new pump and treat facilities to remove hexavalent chromium (Cr(VI)) from groundwater.
    • Oversaw small column testing to identify the preferred ion exchange (IX) resin for Cr(VI) removal. This testing identified three technically viable IX resins for potential use.
    • Participated in multi-discipline teams evaluating the operational constraints and relative costs for each IX resin considered for use. These evaluations identified one of the three candidate IX resins with significantly lower operating costs over the operating lifetimes.
    • Led a multi-discipline team to resolve operating, safety, and waste management issues related to the use of a disposable IX resin for two new facilities. Resolution of these issues allowed the use of the disposable IX resin and substantial reduction in operating costs.
  • Improve operations in existing facilities
    • Led a multi-discipline team identifying and resolving issues related to converting existing IX facilities from a regenerable resin to a disposable resin; Developed the plan for converting the first facility to using the disposable resin. Conversion of the existing facilities to the disposable resin will reduce operating costs significantly.
    • Led a multi-discipline team resolving issues related to hazardous material management in existing facilities. As a result, operating practices were modified to attain compliance with applicable NFPA codes.
