“REAL-TIME” SOIL CHARACTERIZATION AND REMEDIATION DEMONSTRATION PROJECT
Argonne National Laboratory, UK, industry and PGDP scientists developed and demonstrated a tailored, site-specific approach to utilize state-of-the-art field instrumentation to conduct a PGDP soil/sediment project from characterization through remediation and verification of cleanup. The ‘Real Time’ Demonstration Project (RTD) accomplished characterization and cleanup of PCB, metal, and radionuclide contamination on the 16-acre AOC-492 site (Figure 1) in a 3-week field mobilization versus the typical 3-4 years necessary for completing existing iterative field project life cycles.
The Project integrated key conceptual approaches from Argonne National Laboratory, the Adaptive Sampling and Analysis Plan (ASAP) approach, and the Environmental Protection Agency TRIAD approach. Following Project completion TRIAD and ASAP training was provided to PGDP DOE staff, PGDP Contractor Staff, University staff, EPA Staff, Kentucky regulators and the public.
Preliminary RTD project efforts included rigorous testing to verify performance and project suitability for X-ray Fluorescence (XRF) metal quantification field instruments and PCB field test kits. XRF performance verification was conducted with the assistance of private industry and PCB field test kit performance verification was conducted cooperatively with USEPA’s Technology Innovation Field Services Division (Las Vegas).
The RTD Project technology suite (Figure 2) included: 1) Logged gamma walkover surveys (GWS) for gamma-emitting radionuclides; 2) Discrete in- situ gamma measurements (Figures 3-6); 3) In-situ High Purity Germanium (HPGe) gamma spectroscopy for radionuclides; 4) In-situ and ex-situ (XRF) for metals including total uranium; and 5) field test kits for polychlorinated biphenyls (PCBs). Multi-increment sampling and adaptive compositing techniques were included in the dynamic work strategy applied to the study area. In addition to in-situ and ex-situ measurements accomplished in the field, composite samples were analyzed by fixed laboratory to support the real-time technologies.
The Real Time Technology Application Demonstration Project Final Report and Project Concept Presentations discuss the Project approach and the application of field and laboratory methods.

DESIGN OF COST-EFFECTIVE, REAL-TIME IMPLEMENTABLE,
SEDIMENT AND CONTAMINANT RELEASE CONTROLS
UK Biosystems and Agricultural Engineering Department and KWRRI developed alternative, readily implementable, design options for integrated storm water and sediment control systems for PGDP Outfalls 008, 011 and 015.
The project’s remedial options design process utilized the SEDCAD surface water and sediment release model with historical PGDP watershed flow and sediment concentrations. Outfall watershed discharge and sediment loading were modeled.
Remedial options were required to meet performance objectives, be cost effective, readily implementable, and require minimal excavation disturbance for placement.
Project remedial options and recommendations for future watershed monitoring are provided in the project final report.

SURFACE WATER TOTAL MAXIMUM DAILY LOAD (TMDL) DEVELOPMENT
The Kentucky Water Resources Research Institute (KWRRI), Murray State University, and UK Civil Engineering conducted an extensive hydrologic and water quality evaluation of the PGDP and associated watersheds.
TMDL Development Project Phase 1 compiled and assessed available surface water flow and water quality data to develop TMDL criteria for surface water associated with the PGDP.
Based on TMDL Phase 1 data assessment it was determined that additional field data were needed to complete evaluation and recommendations for Cu, Fe, Pb, and Hg in Bayou and Little Bayou Creeks. During 2009 the TMDL Phase 2 Project collected supplemental metal-of-interest data from Bayou Creek, Little Bayou Creek, and reference locations.
The project final report discusses the evaluation of supplemental data and provides TMDL recommendations.
Field data locations for the collection of metals data for Phase II of the TMDL project.
