Chemical Manufacturing Facility

Nitro, West Virginia

Roux Associates was retained to conduct a RCRA Facility Investigation (RFI) and Verification Investigation (VI) for a 100 + acre chemical manufacturing facility located in Nitro, West Virginia. Constituents of concern included volatile organic compounds (VOCs), herbicides, metals and dioxins. Impacted media at the site included soil, groundwater, sediment and surface water. Solid waste management units (SWMUs) at the site included former land disposal areas, lagoons, waste burning areas, incinerators, a wastewater treatment plant and facility sewer system. The United States Environmental Protection Agency (USEPA) Region III was the lead oversight agency for the corrective action program.

Project activities included:

  • development of a strategic plan for RCRA compliance
  • completion of the RFI and VI Work Plans
  • implementation of the RFI and VI Work Plans
  • evaluation and implementation of the technical feasibility and cost-effectiveness of interim corrective measures for the site
  • preparation of a site-specific risk assessment
  • preparation and implementation of surface water and sediment sampling plans
  • preparation of a site database using EQuIS® software systems
  • prepared the Environmental Indicator (El) for Migration of Contaminated Ground-Water Under Control for the facility
  • completion of the Corrective Measures/Stabilization Study for proposed engineering controls for the closure of remaining surface impoundments and groundwater treatment alternatives.

    • Interim corrective measures (IRMs) at the site implemented by Roux Associates included the recovery of separate phase kerosene and dissolved phase VOCs from an approximate one-acre area of the site. Roux Associates prepared detailed design specifications for the installation of four extraction wells to recover LNAPL and impacted groundwater. The extracted groundwater was piped to the on-site treatment plant prior to discharge under permit.

    Roux Associates also completed a surface water/groundwater interaction model to develop site-specific dilution factor for groundwater constituents that potentially discharge to the adjacent river. The surface water contaminant concentrations developed through the model were used to support the Risk Assessment completed at the site.
