Contaminated Soil Volume Estimate Summary - Luckey Site

1 Method The USACE and ANL utilized the method developed by ANL to estimate contaminated soil volumes at the Luckey Site. The method, known as the Bayesian Approaches for Adaptive Spatial Sampling (BAASS), utilizes both “soft” and “hard” data to generate a probability that a given area will exceed COC cleanup goals (ANL 2005). Soft data includes aerial photographs, non-intrusive geophysics, gamma walkover surveys, Laser Induced Breakdown Spectroscopy (LIBS) data, anecdotal information, and historical site/process knowledge. This information is used to create an initial conceptual site model (ICSM). After each ICSM was entered into the BAASS software, then hard data (site characterization results) were inputted, and the ICSM was updated. The results of the BAASS model were then exported to ArcGIS [geographic information system (GIS) software suite produced by the Environmental Systems Research Institute]. The ArcGIS software was used to convert the BAASS output into confidence contours, or two-dimensional (2-D) areas that were greater than or equal to a certain probability of exceeding the COC cleanup goals.

The BAASS software simulation described above addressed only the lateral extent (i.e., the area) of contamination based on the ICSM and site characterization data. To convert these areas to in situ contaminated soil volumes, estimations of maximum depths of contamination that exceeded the COC cleanup goals were applied to area results in order to calculate the three-dimensional (3-D) volume of contaminated soil present within each area. The depth estimations were derived from site characterization results and historical information regarding the depth of disposal trenches. For purposes of this ESD the 50% confidence level, or 0.5 BAASS probability, contaminated soil volume was selected as the volume most likely to be excavated.

Based upon the selected confidence level volume of 50%, the in situ contaminated soil volume was then used to develop an in situ construction soil volume. The in situ construction soil volume estimate represents the maximum excavation footprint required to access and remove contaminated material associated with the specified confidence interval. It includes removal of uncontaminated overburden to access contaminated soils, and necessary safety sloping/benching (where required) to ensure worker safety.

2 Initial Conceptual Site Model A BAASS analysis requires developing an ICSM for the site. For the Luckey Site, three ICSMs were created including radionuclide SOR, Be, and Pb. The ICSMs captured the soft information available for a particular area as probabilities of contamination. They present an understanding, absent of sampling data, of where contamination is likely to be found. The contamination probability is captured by a set of grid points overlain on the area of interest - the probability of contamination in an ICSM can and often does vary from grid point to grid point.

Soft data for the Luckey Site included aerial photographs, non-intrusive geophysics, gamma walkover surveys, LIBS data, anecdotal information, and historical site/process knowledge. Based on available soft information, individual grid nodes were assigned various contamination probabilities.

3 Data Evaluation The soil analytical data used to generate the volume estimate was compiled from two USACE investigation data sets. The Remedial Investigation (RI) (USACE 2000) data set included the U.S.

Department of Energy’s radiological survey data (1990), the USACE Phase II characterization data (1997), and the USACE RI data (1998). The Excavation Volume Uncertainty data set includes the sampling conducted in 2009 and 2010 as part of the Excavation Volume Uncertainty Investigation (USACE 2011).

Utilizing the Ra-226, Th-230, U-234, and U-238 (only Ra-226 when the other isotope analytical data was unavailable) results, a SOR was calculated for each soil sample. The SOR was calculated using the data set specific arithmetic mean (average) background values and COC cleanup goals presented in Table 1.

Note that the ROD specifies the use of the 95th upper tolerance limit (95th UTL) for calculation of a background threshold level. However, determination of net radioactivity above background using an upper limit to background results in a lower net radioactivity source term. The use of the arithmetic mean (rather than an upper background threshold value) is more conservative.

After subtracting average background, each radionuclide result is divided by its respective cleanup goal.

The fractions are then summed to obtain the final SOR for each sample. A sample with an SOR greater than one is considered to “fail” and require remediation.

Where multiple samples were collected at various depths from a single location, the maximum SOR value was used regardless of the depth at which it occurred since BAASS can only handle one input for each unique location. USACE ensured a more conservative approach to volume estimating in this manner. Sample locations with a SOR greater than or equal to one were assigned a contaminant weighting of one in the BAASS software. Those with a SOR below 1 were assigned a value of 0.

The Be and Pb results were simply compared to the respective cleanup goals and sample locations with a result greater than the cleanup goal were considered to “fail” and require remediation (e.g. assigned a value of 1). Similar to the SOR, where multiple samples were collected at various depths from a single location, the maximum Be or Pb value was used regardless of the depth at which it occurred.

The data evaluated for this modeling effort has been included as an attachment.

4 Bayesian Approaches for Adaptive Spatial Sampling BAASS requires three additional key parameters: a variogram1 function, the range for the variogram selected, and a search neighborhood. The variogram functional form combined with its range captures beliefs about the spatial autocorrelation present. The search neighborhood determines which sampling locations can contribute to the updating process at any particular grid node. The variogram functional form and range, in conjunction with the spatial pattern of sampled locations, determines how much “weight” each sampled location has in estimating the probability of contamination at a grid node.

Bayesian updating is used to merge each ICSM probability with those obtained from the indicator

1 A variogram is a graph that characterizes the spatial continuity or roughness of a dataset.

Kriging2 of the contaminated weighting factors. For the Luckey Site, 61 meters (200 feet) was used for both the radius of the search neighborhood and for the range of the variogram. The functional form of the variogram was set to exponential. After updating, areas distant from sampled locations generally have contamination probabilities that reflect each ICSM, while densely sampled areas have probabilities that reflect the results of sampling.

5 Lateral Extents The output from BAASS was an updated probability for each grid node (i.e., each ICSM is updated with the hard data). The data was turned into a point file and projected onto the base map using ArcGIS; the grid nodes could then be displayed such that the footprint for any given probability could be shown. For example, all points with a probability ≥ 0.5 may be displayed as colored dots, while all others are not displayed. This would show the footprint for the area of the site with a BAASS probability of 0.5 or greater. To arrive at the final footprint, the grid nodes were converted into a raster data layer in order to provide a continuous surface. This raster data layer was contoured, at the specified probability, to create polygons representing the contaminated footprints. Figure 1 presents a map of the Luckey Site with the BAASS 0.5 probability nodes and the resulting contaminated soil footprint polygons for radionuclide SOR, Be, and Pb.

The main drainage ditch, that runs north-south and extends from the northeast boundary of the Luckey Site and discharges into Toussaint Creek, was not included in the Bayesian analysis. Engineering judgment was used to estimate a volume of radionuclide and beryllium contaminated material in this linear feature on the basis of sediment and soil samples collected from within and along the banks of the drainage ditch.

6 Three-Dimensional Modeling In order to generate a contamination volume, 3-D modeling was conducted using ArcGIS Spatial Analyst and 3-D Analyst Extensions. The 50% probability level contours for radionuclides (SOR), Be, and Pb were combined and used as the basis for the initial in situ contaminated soil volume (i.e., prior to excavation).

The in situ soil volume was further modified by incorporating engineering aspects of soil excavation, including safety sloping/benching.

The in situ volume of contaminated soils was calculated by determining the “top” and “bottom” elevation of contamination at each sampling location. Little clean overburden is found at the Luckey Site so the topographic surface elevation was conservatively selected as the “top” elevation. The “bottom” elevation of contamination was set at the maximum depth below grade surface (bgs) at which a sample with a subsurface SOR, Be, or Pb exceedance occurred. If SOR, Be, or Pb results were separated vertically by one or more acceptable samples, the deepest elevated sample was used to vertically bound the extent of FUSRAP-related contamination.

2 Kriging predicts the value of a function at a given point by computing a weighted average of the known values of the function in the neighborhood of the point.

For unbounded sample locations within the disposal trench area located within the northeastern corner of the site, the available soft data, including geophysical surveys and anecdotal evidence regarding the depths of the disposal trenches (USACE 2000), was utilized. If a vertically unbounded sample was located within the footprint of a disposal trench, the “bottom” surface was the anecdotal trench depth for that sample location.

These bounding values were then used to generate 3-D surfaces utilizing ArcGIS 3-D Analyst to represent the simulated top and bottom of the soil contamination for radionuclides, Be, and Pb. The in situ contaminated soil volume of each area of excavation was generated by calculating the difference between the bottom and top of contamination within ArcGIS for each area.

The cutback soil volume was determined by calculating necessary safety side slopes, based on a 2:1 horizontal to vertical slope, for all portions of the contaminated soil footprint greater than five feet in depth, per the USACE Safety and Health Requirements Manual (USACE 2008). Adding the in situ cutback soil volumes to the in situ contaminated soil volume yields the total in situ construction soil volume.

The final volume resulting from this process represents the best engineering estimate of both the in situ contaminated and in situ construction volumes of soil generated during excavation activities for the Luckey Site Selected remedy alternatives. Because the final excavation footprint areas include engineering aspects of the excavation process, the associated areas (and therefore volumes) are larger than the in situ contaminated volumes. Figures 2 and 3 represent the modeled lateral extent and depth of FUSRAP-related contaminated Soils/Fill/Debris, respectively.

7 Waste Volumes Due to the various intersections of surfaces of the three separate ICSMs, seven different potential soil waste streams are anticipated for the Luckey Site:

• Soil contaminated solely with Be (Be concentration exceeds 131 mg/kg);

• Soil contaminated solely with radionuclides (LARW) (SOR greater than 1);

• Soil contaminated with radionuclides and Be (SOR greater than 1 and Be concentration exceeds 131 mg/kg);

• Soil contaminated solely with Pb (Pb concentration exceeds 400 mg/kg);

• Soil contaminated with Pb and Be (Pb concentration exceeds 400 mg/kg and Be concentration exceeds 131 mg/kg);

• Soil contaminated with radionuclides and Pb (SOR greater than 1 and Pb concentration exceeds 400 mg/kg); and

• Soil contaminated with radionuclides, Pb, and Be (SOR greater than 1, Pb concentration exceeds 400 mg/kg, and Be concentration exceeds 131 mg/kg).

Depending on the selected disposal facility or facilities, these are likely to be consolidated into four soil waste streams:

• Soil contaminated solely with Be;

• Radionuclide-contaminated soil that may or may not contain Be;

• Pb-contaminated soil that may or may not contain Be; and

• Radionuclide and Pb-contaminated soil that may or may not contain Be.

• Table 1 summarizes in situ and ex situ contaminated soil volume estimates for each of the four likely soil waste streams and potentially clean cutback soils for the Luckey Site. Figure 2 represents the modeled lateral extent of the FUSRAP-related contaminated soils/fill/debris.
