B.F. Goodrich Superfund Site RI/FS
NES assisted in numerous facets of the RI/FS at the B.F. Goodrich Superfund Site in Calvert City, Kentucky. NES assisted its client in the development and negotiations with EPA of the scope and content of the core RI/FS plans, e.g., Sampling and Analysis Plans (SAPs) for seeps, surface water (river and ponds), sediments, and core drilling and sampling; the Data Management Plan; and the Quality Assurance Project Plan (QAPP). The SAPs were prepared for each Area of Investigation (AOI) designated for study under the RI/FS. Intricacies of the SAPs included procedures for the following:
- Identification of the presence of dense non-aqueous phase liquid (DNAPL) in cores;
- Surface water sampling at discrete depths in the Tennessee River below the Kentucky Dam to include linear sampling from the shore;
- Sediment sampling of the river bottom;
- Pore water sampling of interstitial sediment; and
- Determination of the flow of seeps and collection of seep samples.
Over a three-year period, NES participated in all aspects of the various field activities to implement the RI/FS. NES shared responsibilities with the main RI/FS contractor overseeing various aspects of drilling activities that included the collection and staging of cores for DNAPL investigation, stratigraphic identification, sampling, and the preparation of selected cores collected in Shelby Tubes for physical testing and photography. NES personnel assisted in the installation of transducers in select groundwater monitoring wells along the Tennessee River to collect ongoing groundwater levels. NES personnel developed groundwater monitoring wells using surge blocks and bailers, collected groundwater samples, and bailed/pumped DNAPL from affected wells.
NES personnel performed daily tasks for the seep investigation. These tasks included observing, documenting, photographing, and measuring the flow of seeps along the south bank of the Tennessee River. NES conducted several water quality-sampling events of the seeps using the procedures developed for the SAP.
NES reviewed subcontractor proposals submitted from firms for everything from direct push and core drilling subsurface sampling to boat rental and performance of support for river sampling. NES shared responsibilities to ensure that the selected Tennessee River support contractor provided the necessary equipment, properly used the equipment, and followed the SAP procedures to provide defensible data. The Tennessee River field events included the following:
- Documenting accurate locations using a hand held Global Positioning System (GPS);
- Sampling surface water at discrete depths and linear distances from shore using a “bomb” sampler;
- Sampling sediment at the river bottom and near shore using a Van Veen grab sampler or Ponar grab sampler; and
- Ensuring a stable sampling platform in the flowing Tennessee River.
NES was an integral member of the field team for each of the river sampling events for the collection of surface water and sediments during the three river stages – pool stage, post-pool stage, and falling stage; the collection of surface water, sediment, and biological species in two ponds; and the collection of surface water, sediment, and interstitial sediment pore water in the Barge Slip.
