ABSTRACT
Five borehole samples were collected from the Maywood, New Jersey, Formerly Utilized
Sites Remedial Action Project (FUSRAP) Site Interim Storage Pile and fifteen samples were
collected from various locations on the site and sent to the U.S. Environmental Protection
Agency's National Air and Radiation Environmental Laboratory (NAREL) in Montgomery,
Alabama, for analysis. Each sample was separated by particle size and the resulting size
fractions were analyzed for radioactivity. A petrographic analysis of each sample was
performed. In addition, analyses for volatile organic compounds, pesticides, and metals were
performed on selected samples.
The following conclusions are based on the results of these analyses:
The most abundant radionuclides in the soil samples are thorium-232 and its decay
products. Uranium-238 and its decay products are also present.
The radionuclide concentrations are not evenly distributed throughout the site, although
all but two of the soil samples tested produced similar results in the bench-scale tests used
to assess the potential of soil washing as a remediation technology.
The major source of radioactivity in the sand and silt-size panicles is monazite.
Zircon is also present and contributes a small amount of radioactivity. Three samples
contain calcium-thorium orthophosphate, an industrial process waste, that contribute
appreciable radioactivity in two of these samples.
Monazite and zircon in these samples are essentially insoluble in water. The magnetic
susceptibility of monazite is in the intermediate range while that of zircon is low.
Other particles with high specific gravity have generally higher magnetic susceptibility
than monazite and zircon.
The average specific gravity of the soil panicles is 2.6 g/cc, compared to 4.7-5.4 g/cc
for monazite and zircon.
Material adsorbed on the particle surface likely accounts for the majority of the
radioactivity in the clay-size particles. Chemical precipitates of thorium from the
thorium extraction process are also present and contribute to the radioactivity in the
sample.
ii
-------
The fine sand, silt, and clay-size particles can be removed from all but two of the soils
tested using size separation techniques, resulting in the separation and collection of up
to 80% of the original material. The cleaned soil fraction contains less than 5 pCi/g of
thorium-232, uranium-238, radium-226 or radium-228 radioactivity.
The levels of radioactivity, organic compounds, pesticides, and metals transferred to
the wash water in these tests are below the limits established in 40 CFR part 261.

1.0 Introduction
The Maywood, New Jersey, FUSRAP Site Interim Storage Pile contains approximately
395,000 yd3 of soil contaminated with thorium, radium, and uranium (EPA88). Five borehole
samples (MIS 1-MISS) were collected from the pile in 1991. Figure 1 shows the location of
the five borehole samples. In 1992 fifteen additional samples (MV1-MV15) were collected
from various locations on the Maywood site. The methods used to collect these samples and
maps showing the sample locations are included in Appendix A. These samples were sent to
the National Air and Radiation Environmental Laboratory (NAREL) in Montgomery,
Alabama, for soil characterization analysis. The primary objectives of this analysis were to:
1) Assess the homogeneity of the radionuclide contamination at the site.
2) Determine the physical form of the contamination.
3) Determine if panicle size separation using soil washing techniques would be effective in
reducing the volume of contaminated soil.
4) Determine any additional physical properties of the radionuclide contamination that
might be applied to remediation of the site.
This report briefly describes the tests performed on the soil samples. The results of these
tests are tabulated and included in Appendix B.

Maywood FUSRAP Site Sampling Locations for Samples MIS1-MIS5
-------
2.0 Particle Size Distribution
2.1 WHOLE SOIL
NAREL received twenty soil samples for study. The samples were visually inspected and the
beta/gamma radioactivity was measured using a Geiger/Muller tube. The five borehole samples
collected from the pile were labelled MIS for Maywood Interim Storage Site. The fifteen
samples collected from the site were labelled MV for Maywood Vicinity. The descriptions of
samples MV1-MV15 are listed in Table 1. After initial screening for gross radioactivity, each
sample was thoroughly mixed and dried at 60°C. Each sample was then analyzed for
radioactivity by gamma spectroscopy as described in Section 3.1 prior to further analysis and
alpha spectroscopy as described in Section 3.2.
2.2 VIGOROUS WASH
Each whole soil sample was vigorously washed before further analysis (SCA91a). The
vigorous washing process liberates small contaminated particles from larger uncontaminated
particles and reduces the size of colloidal material. The wash water from each sample was
analyzed for radioactivity by gamma spectroscopy as described in Section 3.1 and for
chemical contaminants as described in Section 4.0.
2.3 WET SIEVING
After vigorous washing, samples MIS 1-MISS were fractionated according to particle size
using ASTME standard test sieves (SCA91b). The samples were separated at 6.3 mm (Vi"),
0.30 mm (50 mesh), 0.15 mm (100 mesh), and 0.075 mm (200 mesh). Samples MV3-MV5,
MV7-MV12, MV14, and MV15 were separated as described above, with additional
fractionation at 1.18 mm (16 mesh), 0.60 mm (30 mesh), 0.106 mm (140 mesh), 0.053 mm
(270 mesh), and 0.045 mm (325 mesh) to provide additional particle-size distribution
information. The resulting fractions were dried at 60°C, analyzed for radioactivity as
described in Section 3.0, and analyzed petrographically as described in Section 5.0.
2.4 VERTICAL-COLUMN HYDROCLASSIFICATION
Vertical-column hydroclassification is a method for separating contaminated soils by size,
2-1
-------
which closely simulates the process used by full-size hydroseparation equipment. The
technique is based on Stokes' Law, which states that the settling velocity of a particle in
liquid is dependent upon the effective diameter of the particle, the density of the particle, and
the density and viscosity of the liquid. By adjusting the flow rate of the water stream in the
direction opposite to the settling panicles, a separation based on the effective panicle size can
be made if the liquid viscosity and liquid and mean particle densities remain constant.
After vigorous washing, samples MIS1-MIS5 were sieved at 6.3 mm, and the undersize
particles were added to the top of a water column flowing at a constant rate. The soil for
each sample was separated at flow rates designed to be effective for particle diameters of
0.25 mm (60 mesh), 0.15 mm, and 0.075 mm. Samples MV1, MV2, MV6, and MV13 were
separated using the same procedure after being sieved at 1.18 mm and 0.60 mm in addition to
6.3 mm before being hydroclassified. These samples were additionally separated at
0.106 mm, 0.053 mm, and 0.045 mm by hydroclassification (SCA91c). The resulting
fractions were dried at 60°C and analyzed for radioactivity as described in Section 3.0 and
analyzed petrographically as described in Section 5.0.
Samples MV1 and MV13 were selected for hydroclassification separation based on the results
of the gamma spectroscopy results shown in Tables 2-1 and 2-13. Sample MV1 contains the
highest levels of contamination, while sample MV13 contains an average level of
contamination. Samples MV2 and MV6 were selected based on the appearance of the soil.
Sample MV6 is a black silty soil, while sample MV2 contains large chunks of
gypsum/carbonate.
2.5 SEDIMENTATION
Sedimentation is a method for separating fine panicles by size. The technique is based on
Stokes' Law and is similar to vertical-column hydroclassification. The particles are
distributed throughout a column of water and allowed to stand for a period of time sufficient
to allow particles of a specific effective diameter to settle a measured distance. The process
is repeated up to eight times to effect a separation.
After vertical-column hydroclassification, the size fractions containing particles smaller than
.045 mm (-.045 mm) for samples MV1, MV2, MV6, and MV13 were separated using
sedimentation (SCA91d). The samples were allowed to settle for periods of time designed to
2-2
-------
be effective on particle diameters of 0.020 mm, 0.010 mm, 0.005 mm, and 0.002 mm. The
resulting fractions were dried at 60°C and analyzed for radioactivity as described in
Section 3.0 and analyzed petrographically as described in Section 5.0.
2.6 WASH WATER
After vigorous washing, each sample was filtered through a 0.022 mm Whatman 1 filter to
separate the solids from the wash water. The wash water samples for MIS1-MIS5 were
combined, and the composite sample was analyzed by gamma spectroscopy as described in
Section 3.1. The composite sample was also analyzed for volatile organic compounds,
pesticides, and metals as described in Section 4.0. Each wash water sample for MV1-MV15
was analyzed by gamma spectroscopy as described in Section 3.1 and for arsenic as described
in Section 4.4.
2.7 RESULTS
The weight percentages of the individual size fractions are listed in Appendix B. The sieve
separation results are located in Tables 2-3 through 2-5, 2-7 through 2-12, 2-14 through 2-16,
2-18, 2-20, 2-22, and 2-24. The hydroclassification results are found in Tables 2-1, 2-2, 2-6,
2-13, 2-17, 2-19, 2-21, 2-23, and 2-25. In addition, Tables 2-1, 2-2, 2-6, and 2-13 include the
results for the sedimentation separations.

3.0 Radiochemical Analysis
3.1 GAMMA SPECTROSCOPY
Each whole soil sample, panicle size fraction, and wash water was analyzed for gamma
emitting radionuclides using high-purity germanium detectors (EPA80). Three separate
aliquots of each of the 15 whole soil samples collected from the site were analyzed to obtain
average radionuclide concentrations for that sample location. Two aliquots of each of the 5
borehole samples of the pile, which constituted the entire sample, were analyzed for gamma
emitting radionuclides. The sample size for each analysis is listed in Tables 2-1 through
2-25. The samples were counted for a maximum of 1000 minutes. The major radionuclides
identified in the samples were radium-226 and radium-228. Tables 2-1 through 2-25 list the
radium results for each gamma analysis along with the 2-sigma counting uncertainty. Gamma
specrroscopy was performed on heavy mineral fractions, separated as described in Section 5.0,
containing sufficient material (10 g or more) for the analysis. These results are listed in
Table 8. When no radioactivity was detected, the minimum detectable concentration (MDC)
is listed.
3.2 ALPHA SPECTROSCOPY
Aliquots of each whole soil sample, particle size fractions from samples MIS2 (sieved), MV1,
MV6, MV8, MV13, and heavy mineral fractions from MV1 were solubilized in hot acid
mixtures. The sample size for each analysis is listed in Tables 3-1 through 3-7. Uranium
was extracted from the mixture, coprecipitated with lanthanum fluoride carrier, and analyzed
by alpha spectroscopy (EPA84). Thorium was separated by ion-exchange chromatography,
coprecipitated with lanthanum fluoride carrier, and analyzed by alpha spectroscopy (EPA84).
The uranium-238 and thorium-232 results are listed in Tables 3-1 through 3-7.
Sample MIS2 was selected as representative of the samples from the Maywood pile for
individual size fraction analysis based on the sample appearance and radionuclide
concentrations found in the whole soil. Samples MV1 and MV6 were selected for individual
size fraction analysis because of the relatively high levels of radium remaining in each of the
size fractions. The particles between .020 and .045 mm separated from sample MV1 were
not analyzed by alpha spectroscopy because all the size fraction was used for the heavy
mineral separation. Samples MV8 and MV13 were selected as representative of the average
3-1
-------
contaminated soil on the Maywood FUSRAP site based on sample appearance and
radionuclide concentrations found in the whole soil, and were separated by sieving and
hydroclassification, respectively. Alpha spectroscopy was performed on the heavy mineral
fractions separated from sample MV1 as described in Section 5.0. These results are listed in
Table 3-3.

4.0 Chemical Containments
The determination of the panicle size distribution of arsenic in the Maywood soil was
requested as part of this project. In order to comply with disposal requirements for the wash
water used in these experiments, it was necessary to perform several analyses on selected
sample fractions. The different analyses performed are described in this section.
4.1 VOLATILE ORGANIC COMPOUNDS
The composite wash water sample from samples MIS1-MIS5 was analyzed for volatile
organic compounds using EPA Method 8240. The results of this analysis are listed in
Table 4.
4.2 PESTICIDES
The composite wash water sample from samples MIS1-MIS5 was analyzed for pesticides
using EPA Methods 8080 and 8140. The results of this analysis are listed in Table 5.
4.3 METALS
The composite wash water sample from samples MIS1-MIS5 was analyzed for the 22 Target
Analyte List (TAL) metals and mercury using inductively coupled plasma. The results of this
analysis are listed in Table 6-1. The eleven individual particle size fractions for sample
MV13 ranging from greater than 6.3 mm (+6.3 mm) through smaller than .020 mm and
greater than .010 mm (-.020/+.010 mm) were analyzed for the 22 TAL metals plus boron and
molybdenum. The results of these analyses are listed in Table 6-2. Sample MV13 was
selected as representative of the soil on the Maywood site. The smallest size fractions,
-.010/+.005 mm, -.005/+.002 mm, and -.002 mm, were not analyzed because the
concentrations of radionuclides in these fractions were greater than could be accepted by the
U.S. Army Corps of Engineers Laboratory performing the analyses.
4.4 ARSENIC
Arsenic was identified as a potential problem at the Maywood FUSRAP site. In addition to
the specific size fractions analyzed for arsenic as described above, samples MV2-MV15 were
4-1
-------
analyzed for the presence of arsenic in the whole soil. The wash water from samples MV1
through MV15 were also analyzed for the presence of arsenic. The results of these analyses
are listed in Table 7. The particle size fractions for sample MV13 were analyzed for arsenic
as described in Section 4.3, and the results are listed in Table 6-2.
4-2
-------
5.0 Petrographic Analysis
Petrographic examination was performed on the Maywood FUSRAP site samples in
accordance with the Office of Radiation and Indoor Air (ORIA) Characterization Protocol for
Radioactive Contaminated Soils (EPA92). The purpose of this examination is to determine
the physical properties and waste forms of the radioactive contaminants and the distribution of
the waste forms within the various size fractions. The physical properties of the soils are
used to assist in the assessment of selected remediation methods.
The samples were separated by size as described in Section 2.0. The heavy (more dense)
minerals in the -0.30/+0.15 (or -0.25/+0.15 for hydroclassified fractions), -0.15/+0.106,
-0.106/+0.075, -0.075/+0.053, -0.053/+0.045, and -0.045/+0.020 mm fractions for each sample
were separated by the sink-float method using a solution of sodium polytungstate with a
density of 2.89 g/cc (CAL87). The density separations for heavy minerals facilitate the
identification of waste forms and indicate the potential for separating radioactive material
using density techniques.
The composition of the gravel (+6.3 mm) and the coarse sand (-6.3/+0.60 mm) size material
was determined by megascopic (visual) methods. The sand and coarse silt-size material
(-0.60/+0.045 mm) was examined using both binocular and polarizing petrographic
microscopes. Heavy mineral fractions from this size range were also inspected with the
petrographic microscope. A statistical count of 150 to 300 particles was obtained from each
size fraction and each heavy mineral fraction. The fine silt and clay-size particles
(-0.045 mm) were analyzed by x-ray diffraction. The average mineral composition for each
sample is listed in Table 9-1 for the Maywood site samples and Table 9-2 for the Maywood
pile samples. The results of the petrographic examinations of the individual size fractions for
samples MV1-MV15 are listed in Tables 10-1 through 10-15. The average composition of
the heavy mineral fractions for the Maywood site samples are listed in Table 11. Table 11-1
shows the average composition in the sand size particles, while Table 11-2 shows the average
composition in the silt size particles.

6.0 Discussion
6.1 GAMMA SPECTROSCOPY
Each whole soil sample, panicle size fraction, wash water, and selected heavy mineral
fractions were analyzed for gamma emitting radionuclides using high-purity germanium
detectors. The results listed in Tables 2-1 through 2-25 show the radium-226 and
radium-228 activities for each analysis. No artificially produced radionuclides were detected,
and no significant levels of other radionuclides were detected other than the decay products of
uranium-238 and thorium-232.
The radium-226 concentration calculation is based on the 186 keV gamma ray with an
intensity of 3.28% (DOE81). The radium-228 concentration calculation is based on the 911
(27.7% intensity) and 969 keV (16.6% intensity) gamma rays. A minimum detectable
concentration of 0.2 pCi/g for each radionuchde is achieved for most measurements.
The concentrations of radionuclides detected in the whole soil samples varied from
0.604 pCi/g radium-228 in sample MV7 to 259 pCi/g radium-228 in sample MV1. The
background levels for the Maywood FUSRAP site are estimated to be approximately
1-1.5 pCi/g radium-226 and 1 pCi/g radium-228. This estimate is based on the lowest
radionuclide concentrations measured for the twenty samples. The average concentrations for
samples MV2-MV15 are 3.0 pCi/g radium-226 and 4.5 pCi/g radium-228, calculated from the
mean activities for the whole soil samples. The average radionuclide concentrations for the
borehole samples MIS 1-MISS are 6.3 pCi/g radium-226 and 17 pCi/g radium-228.
Every sample tested indicates that the majority of the radioactivity is associated with the silt
and clay-size particles. Sample MV13 contains an average of 4.36 pCi/g radium-228 in the
particles greater than .045 mm in diameter (weighted mean based on fraction weight), but the
particles less than .002 mm in diameter contain 64.6 pCi/g, almost fifteen times that amount.
Similar increases in radionuclide concentrations for the smallest particle sizes are seen in all
of the samples tested, even samples MV1 and MV6 where the radionuclide concentrations in
the coarser particles remain above 5 pCi/g.
Figure 2 compares the gamma spectroscopy results for the wet sieved fractions of sample
MIS 1 to the gamma spectroscopy results for the hydroclassified fractions of the same sample

(see Tables 2-16 and 2-17). The average concentrations of radium-226 and radium-228 were
calculated for a simulated panicle size separation at .075 mm (200 mesh), along with the
weight percent that would be found in each fraction. The results show that 64.1% of the soil
would have the radium-228 concentration reduced from 23.2 pCi/g to 2.42 pCi/g through the
use of soil washing and sieving, while 67.3% of the soil would be reduced to 2.24 pCi/g
through the use of soil washing and hydroclassification separation techniques. The difference
between the two methods is less than the combined uncertainties in the sample selection, the
radiation measurements, and the weight measurements. The total uncertainty in these
measurements is estimated to be ±10%.
The radium-228 concentration is equal to or greater than the radium-226 concentration for
most of the samples analyzed. As the radioactivity in a sample fraction approaches
background, the radium-228 concentration approaches the radium-226 concentration. As the
radioactivity in a sample fraction increases, the ratio of radium-228 concentration to
radium-226 concentration increases. This ratio is as high as 7.4:1 for the -.15/+.106 mm
particles separated from sample MV1, but is generally less than 2:1 for other samples. Most
examples discussed involve the radium-228 concentration, because this is generally the higher
of the two radionuclide concentrations.
Figure 3 is a graph showing the average radium-228 concentration of all particles greater than
a given particle diameter for samples MV6 and MV13. If the soil were separated at the
indicated particle size, the oversize material would contain the radium-228 concentration
indicated. This graph can be used to predict whether a particular soil can be remediated
using particle size separation by finding the smallest particle size separation that produces an
oversize fraction concentration below the cleanup standards for the site. Figure 3 has a
horizontal line at 5 pCi/g above background, or 6 pCi/g. This is an arbitrary clean-up standard
that is presented here only to illustrate the use of this figure. Figure 3 shows that panicle
size separation of sample MV6 at 6.3 mm would produce a remediated fraction with a
concentration below the cleanup criterion. Table 2-6 lists the weight percent of the sample
that could be remediated as 2.37%. Any size separation below 6.3 mm would produce a
remediated fraction with a concentration above the cleanup criterion. MV13, however, shows
that a particle size separation at 0.010 mm produces an oversize fraction with a radium-228
concentration of 5.61 pCi/g. Summing the weight percents for the panicle sizes listed in
Table 2-13 illustrates that 89.7% of the material could be remediated for this sample.

6.2 ALPHA SPECTROSCOPY
Each whole soil sample and selected particle size fractions were analyzed for alpha emitting
radionuclides. The purpose of these measurements was to determine the equilibrium
conditions for the uranium-238 and thorium-232 decay series. By measuring the parent
radionuclides, uranium-238 and thorium-232, and the long lived daughter radionuclides,
radium-226 and radium-228, respectively, the equilibrium conditions can be determined. The
results of the alpha and gamma spectroscopy analyses are compared in Tables 3-1 through 3-7.
The largest source of error in the measurement of the alpha emitting radionuclides is sample
aliquoting. The alpha spectroscopy measurement technique is limited by two factors: sample
size and sample radionuclide concentration. If the sample size is too large, it is difficult to
perform the chemical purification procedure. If the radionuclide concentrations are too high,
the detectors can be contaminated and will require replacement. The samples analyzed by
alpha spectroscopy were limited to a maximum of one gram of sample and a maximum of
10 pCi per nuclide being measured. The sample size for the gamma analysis was generally
500-1000 times greater than the sample size for the alpha analysis. The large sample aliquot
analyzed by gamma spectroscopy, generally the entire sample or sample fraction, eliminates the
uncertainties associated with analyzing extremely small aliquots of the sample by alpha
spectroscopy. This means that the results from the gamma spectrometry analyses are more
representative of the whole sample than the results from the alpha spectroscopy analyses.
The comparison between the alpha and the gamma analyses for the whole soil samples
demonstrates that radium-228 and thorium-232 are in equilibrium; that is, the radium-228
concentration is equal to the thoriurn-232 concentration. Sample MV1 contains almost twice
as much thorium-232 as radium-228, but this is probably due to aliquoting errors from the
small sample size analyzed for alpha spectroscopy. The individual size fractions from MV1
show that the sample is in equilibrium (Table 3-2). The equilibrium of uranium-238 and the
radium-226 is more difficult to determine. Some samples, such as MV1, have virtually
identical measurement values, 106 pCi/g uranium-238 and 107 pCi/g radium-226. Other
samples contain considerably less uranium-238 than radium-226, such as 2.41 pCi/g and
6.17 pCi/g, respectively, for sample MV13. All the samples show that the uranium-238
concentration is equal to or less than the radium-226 concentration. In each case, using the
radium concentration to estimate the concentration of the parent radionuclide will produce a
conservative result.
6-5
-------
The individual size fractions were analyzed for five of the samples, MV1, MV6, MV8,
MV13, and MIS2 (Tables 3-2 through 3-7). A comparison between the parent and daughter
activities for each decay series indicates if soil washing and particle size separation disrupts
the equilibrium. There is reasonable agreement for all the size fractions for each of the
samples tested. There is evidence that the radioactivity in the sand-size particles
(-6.3 mm/+.075 mm) is associated with certain particles, such as monazite, and not evenly
distributed throughout the entire sample, as well as evidence that the uranium and thorium are
associated with different types of particles. For example, with particles between . 106 and
.15 mm in sample MV1, there is good evidence to suggest equilibrium between uranium-238,
26.7 pCi/g, and radium-226, 24.8 pCi/g. These same particles show thorium-232, 66.3 pCi/g,
and radium-228, 184 pCi/g, out of equilibrium. This demonstrates that the sample is non-
homogeneous, and that the particles containing the uranium concentration was evenly
represented, while the particles containing the thorium concentration were not. Sample MV1
shows opposite results for the panicles between .075 and .106 mm. Uranium-238, 35.8 pCi/g,
and radium-226, 67.7 pCi/g, are out of equilibrium, while thorium-232, 139 pCi/g, and
radium-228, 163 pCi/g, are in equilibrium.
The heavy mineral fractions (specific gravity >2.89) for sample MV1 were analyzed by alpha
spectroscopy for comparison between the heavy minerals (Table 3-3) and the whole size
fraction (Table 3-2). Only two size fractions, -.25/+.15 mm and -.60/+.25 mm, contained
sufficient heavy minerals to perform a gamma analysis. The heavy mineral fractions show an
increase in the ratio of thorium-232 to uranium-238. The average ratio of thorium to uranium
for these size fractions is 4.0 (Table 3-2), while the average ratio for the heavy mineral
fractions is 8.8 (Table 3-3). This indicates that while the thorium is strongly associated with
the heavy minerals, the uranium is associated with minerals with specific gravity below 2.9 as
well as with the heavy minerals. The concentrations of both radionuclides in the heavy
mineral fractions remains reasonably constant throughout the size range. The thorium-232
varies between 1530 pCi/g for the -.60/+.25 mm particles and 2430 pCi/g for the
-.053/+.045 mm particles, an increase of only 60%.
6.3 CHEMICAL CONTAMINANTS
The composite wash water from samples MIS1-MIS5 from the Maywood FUSRAP site pile
was analyzed for chemical contaminants to determine if any hazardous concentrations of these
contaminants were transferred to the water during soil washing operations. The analyses
6-6
-------
show that no appreciable quantities of solvents or pesticides are transferred to the wash water
(Tables 4 and 5). Acetone was the only solvent detected, and no pesticides were detected in
the wash water. Calcium, potassium, magnesium, and sodium are the most abundant metals
transferred to the wash water (Table 6-1).
Each panicle size fraction greater than .010 mm in diameter from sample MV13 was
analyzed for boron, molybdenum, and the 22 TAL metals (Table 6-2). Several metals have
elevated concentrations in the large particle sizes, low concentrations in the medium size
ranges, and elevated concentrations for the small size ranges. These include arsenic,
aluminium, barium, boron, calcium, chromium, cobalt, copper, iron, magnesium, manganese,
nickel, potassium, sodium, vanadium, and zinc. Lead appears to be concentrated in the
smaller size fractions. Antimony, beryllium, cadmium, molybdenum, selenium, silver, and
thallium were not detected or detected at very low levels intermittently. None of the metals
detected in the Maywood soils exceeded the levels of concern listed in 40 CFR 261.
Samples MV1-MV15 were analyzed for arsenic in the soil and the wash water (Table 7). The
soil fraction for sample MV1 was not sent for analysis because of the high concentration of
radioactivity in the sample. MV5 contained the highest levels of arsenic in the soil at
23 mg/kg. MV2, MV6, and MV10 also contained small amounts of arsenic in the soil. All
the other samples contained less than 10 mg/kg of arsenic. MV4 and MV10 contained the
most arsenic in the wash water, 34 and 33 ug/L, respectively. No arsenic was detected in the
wash water from samples MV1, MV12, MV14, and the composite sample from MIS1-MIS5.
40 CFR 261 lists the level of concern for arsenic in solid waste to be 55 mg/kg, and the
regulatory level for arsenic leached from solid waste to be 5.0 mg/L.
6.4 PETROGRAPHIC ANALYSIS
The average mineral and material compositions of the fifteen Maywood, New Jersey, thorium
contaminated soil samples MV1-MV15 (Table 9-1) and the five borehole samples MIS 1-MISS
(Table 9-2) are shown in Figure 4. This average composition is computed as a weighted
average from the several soil fractions. The mineral and material composition of each size
fraction for samples MV1-MV15 and the weight percent of each size fraction are listed in
Tables 10-1 through 10-15. The average compositions of the heavy mineral fractions for
samples MV1-MV15 are shown in Figure 5. This average composition is computed as a
weighted average from each sample. The heavy mineral compositions for samples

MV1-MV15 are listed in Table 11-1 (-.30/+.075 mm) and Table 11-2 (-.075/+.045 mm).
Coarse Fractions (greater than 0.6 mm)
The coarse fractions are those greater than 0.6 mm. These fractions can be readily examined
visually for their composition and physical properties. In this investigation, the coarse
material includes those particles greater than 6.3 mm (gravel) and those panicles between
0.60 mm and 6.3 mm. The weight percent of the coarse fractions in the 15 samples averages
24 percent with ranges between 12 and 57 percent. Except for homogeneous quartz and
feldspar, the composition is unique to the coarse fractions with very minor occurrence in the
median or fine fractions. Radioactivity in these coarse fractions is usually background or
minimal in relation to the finer fractions (Tables 2-1 through 2-15). Samples MV1 and MV6
are the only coarse fractions that contain radionuclide concentrations greater than 5 pCi/g.
The following observations were made during the petrographic examination of the samples,
and are based on the experience of the petrographer:
Rock Groups: Granitic, basalt, sandstone, quartzite, and minor coal are predominantly
subrounded to subangular, dense particles typically with background radioactivity. An
analysis of the rocks, quartz, and man-made materials from sample MV1 was
conducted for radium-226 and radium-228. Calculations from the data for the
+1.18 mm panicles show that less than 5% of the radioactivity in the coarse fraction
of sample MV1 is contained in these three groups (Table 8, MV1 +1.18 mm). This
material has few pores, vugs, or fractures that might mechanically retain radioactive
fines.
Furnace-fired cinder/slag panicles comprise from a few percent to more than half of
some coarse fractions (Tables 10-1 through 10-15). These particles range from
predominantly subrounded, porous, lightweight, and structurally weak material to
panicles tending toward more fiat and less equidimensional shape and with denser,
less porous structure. Most of these panicles contain levels of radioactivity slightly
above background because of minor amounts of uraninite that normally occur in coal
and are retained in coal ash cinders. Radionuclide concentrations above 5 pCi/g that
occur in samples MV1 and MV6, however, appear related to associated thorium
extraction precipitates found in the samples. These precipitates may be mechanically
retained in pores or fractures of the cinders and slag particles. An analysis of the
cinder/slag material from sample MV1 was performed for radium-226 and radium-228
(Table 8, MV1 +1.18 mm). Almost 50% of the radioactivity in the coarse fraction from
sample MV1 is found in these panicles.
6-10
-------
Man-made materials comprise from a few percent for most samples to as much as
20 percent in a few of the coarse fractions (Tables 10-1 through 10-15). These
materials consist of asphaltic road metal, concrete, wood fragments, glass, and ceramic
of variable physical properties. The asphaltic road metal from sample MV13 was
analyzed for radium nuclides. All of this material has negligible radioactivity
(Table 8, MV13).
White to light tan colored gypsum/carbonate rock-like particles occur in three samples
(MV1, MV2, and MV6 in Tables 10-1, 10-2, and 10-6). This industrial material is
equidimensional to flat particle shape, soft, porous to solid, and generally structurally
weak. The material contains about 35% of the radium concentration found in the
coarse fraction of sample MV1 (Table 8, MV1 +1.18 mm). The radioactivity in
sample MV2 is negligible (Table 2-2). This material was probably placed as
lightweight, porous, limestone or dolomite around vats of sulfuric acid that reacted
with carbonate to form gypsum and anhydrite. Any thorium precipitates produced
from the industrial process and dumped as waste with the limestone material may have
been incorporated in the pores of the gypsum/carbonate residue.
Quartz, feldspar, and minor heavy minerals appear in the coarse sand-size material.
This material is subangular, essentially equidimensional, dense, hard, and durable.
These materials are generally free of radioactivity (Table 8, MV1 +1.18 mm).
Median Fractions (.045 mm to .60 mm)
The median fractions are those size fractions between .045 mm and .60 mm. These fractions
were analyzed for mineral composition and physical properties by means of the optical
petrographic microscope and the binocular microscope. The weight percent of these fractions
averages 41 percent with ranges between 20 and 61 percent (Tables 10-1 through 10-15).
The following observations were made during the petrographic examination of the samples
and are based on the experience of the petrographer:
Quartz comprises the bulk (60 to 90 percent) of the material in the medium fractions
of the soil samples (Tables 10-1 through 10-15). The quartz is comprised of clean,
subangular to subrounded hard, durable particles of 2.6 specific gravity. These
panicles are generally free of radioactivity. The light mineral fraction, as well as the
heavy mineral fraction, from sample MV1 -.25/+.15 mm particles was analyzed for
radium-226 and radium-228. The results show that the concentration of radium-228 is
almost 50 times higher in the heavy mineral fraction than in the light mineral fraction
(Table 8, MV1 -.25/+.15 mm).
6-11
-------
Feldspar particles comprise from 5 to 20 percent of the medium fraction (Tables 10-1
through 10-15). These particles are fresh to slightly weathered with essentially
equidimensional panicle shape. The particles are generally hard and durable with a
density similar to quartz and generally free of radioactivity as observed for the quartz
particles discussed above (Table 8, MV1 -.25/+.15 mm Light Minerals).
Heavy minerals (greater than 2.89 specific gravity) generally comprise from 2 to
6 percent of the median fractions (Tables 10-1 through 10-15). Radionuclide
concentrations range from negligible in sample MV4 to highly significant in sample
MV1 (Table 8). Radionuclide concentrations are proportional to the amounts of
monazite and zircon, two radioactive minerals. Figure 6 shows the relationship
between monazite and zircon and the radionuclide concentrations in the samples. The
information in Figure 6 is compiled from the information found in Tables 2-1 through
2-15, Tables 10-1 through 10-15, and Tables 11-1 through 11-2. In general, the higher
the levels of monazite and zircon in the sample, the higher the concentrations of
radium-226 and radium-228. Radionuclide concentrations are near background levels
in soil samples MV2, MV4, MV5, MV7, MV10, MV11, MV12, MV14, and MV15.
Radionuclide concentrations above 5 pCi/g occur in samples MV3, MV6, MV8, MV9,
and MV13, with significant levels in MV1. Samples MV4 and MV10 are exceptional
in containing 10 to 20 percent heavy minerals but lacking in radioactivity. Figure 7
shows two photographs of the silt size heavy mineral fractions from samples MV10
(top) and MV13 (bottom). The photograph of sample MV10 reveals that the heavy
minerals are predominantly artificial augite, with no monazite or zircon present. The
mineral augite is not native to the Maywood soil. The augite particles in the
photomicrograph are seen to be fractured and layered. The visual appearance of the
particles shows that the augite was artificially produced, probably as boiler slag
(KR42). Since the artificial augite contains little radioactivity, its presence in the
absence of monazite and zircon likely explains the exceptional nature of samples MV4
and MV10. The photograph of the heavy mineral particles from sample MV13 shows
several particles of monazite and zircon. Table 11-2 shows that 17% of the heavy
minerals in sample MV13 are monazite and zircon, while MV10 contains less than
0.5% of either mineral. Monazite is the principal ore mineral of thorium. The amount
of thorium oxide in the mineral varies between 3 and 10 percent, while uranium is
approximately 10 percent of the thorium by weight. Monazite has a specific gravity
between 4.7 and 5.5 g/cc, and a hardness of 5.0 to 5.5 using Moh's scale. Zircon is a
zirconium silicate with up to 4 percent substitution of thorium or uranium for
zirconium in the mineral structure. Zircon has a specific gravity between 3.9 and
4.8 g/cc and a hardness of 7.5 using Moh's scale. For comparison gold is 19.3/3.0,
iron is 7.9/5.0, and diamond is 3.5/10.0 for specific gravity and hardness, respectively.
The percentage distribution of the heavy minerals in order of abundance is generally
opaques, amphibole group, garnet, epidote group, zircon, monazite, rutile, and minor
amounts of other minerals. Samples MV4 and MV10 are exceptions in containing
predominantly augite and minor opaque magnetite. The heavy mineral particles are
generally dense, hard, and durable. In sample MV1, the radioactivity is likely related

as the indigenous host material.

-------
to calcium-thorium orthophosphate compounds produced as precipitates from the
thorium extraction processes (see discussion of gypsum/carbonate material in the
section on Coarse Fractions). The radioactivity in sample MV6 is probably related to
the calcium-thorium orthophosphate as well: Figure 8 shows two photographs of the
heavy minerals found in the -.60/+.25 mm particles of sample MV1. The top
photograph shows a particle of calcium-thorium orthophosphate centered in the
picture surrounded by particles of monazite and zircon. The bottom photograph shows
the high concentration of monazite and zircon particles found in this sample.
Man-made cinder/slag, concrete, glass, and gypsum/carbonate comprise from trace
amounts to 5 percent of the median size fractions of soil (Tables 10-1 through 10-15).
The physical properties of these materials are highly variable, but based on the
appearance of the particles, they are probably similar to the same types of particles
separated in the coarse fractions. For example, gypsum/carbonate is soft, less durable,
generally structurally weak, and found in the coarse fractions of samples MV1 and
MV6, which exhibit radionuclide concentrations above background levels. The
radioactivity in MV1 (Table 8, MV1 +1.18 mm Gypsum/Carbonate) and MV6 in these
coarse fractions appears related to thorium orthophosphate compounds incorporated in
this material from the thorium extraction materials occurring at these sample locations.
Clay minerals in the particle size fractions between .045 and .053 mm include trace
amounts of illite/mica, chlorite, and kaolinite (Tables 10-1 through 10-15). Their
significance with regard to potential radionuclide concentrations is discussed in the
fine fraction section.
Fine Fractions (particles less than .045 mm)
The fine fractions comprise all the bulk particles less than .045 mm for all the soil samples.
The fine fraction mineral composition was determined by analysis of x-ray diffractograms in
accordance with the ORIA Soil Characterization Protocol (EPA92). The physical properties
of particles, while not directly observed by this method, may be inferred to be generally
similar to the physical properties observed in the particle description of sand and coarse silt
(median fractions) with the petrographic and binocular microscope. The reported percentages
of mineral composition for the fine fractions are also more qualitative because of the
limitations of the x-ray diffraction method when several mineral phases occur together.
The weight percent of the samples for the fine fractions range between 19 and 63 percent
with an average of 30 percent (Tables 10-1 through 10-15). Mineral composition for the
majority of the samples is, in decreasing order of abundance: quartz, feldspar, clay minerals

(illite, chlorite, kaolinite, montmorillonite), heavy minerals, and very minor amounts of other
minerals. The exceptions are samples MV1, MV2, and MV6 that contain gypsum, anhydrite,
calcite, dolomite, and calcium-thorium orthophosphate and other industrial compounds. The
quantity of these materials could not be sufficiently developed for the MV1 fines because of
inadequate x-ray diffractograms. However, their presence is discemable in the coarse
fractions (see discussion on page 17). The gamma analysis of gypsum/carbonate panicles
picked from the +1.18 mm sieve size material revealed elevated levels of radium-226 and
radium-228 (Table 8, MV1 +1.18 mm).
The clay minerals comprise between 20 and 55 percent of the fine fractions (Tables 10-1
through 10-15). The general order of abundance of the clay minerals, except for two samples
(MV4 and MV10), are illite, chlorite, and kaolinite; illite constitutes half of the clay mineral
suite. The clay mineralogy of samples MV4 is MV10 are generally similar in that
montmorillonite makes up approximately 50 percent of the clay minerals for these two
samples (Tables 10-4 and 10-10). The remaining illite, chlorite, and kaolinite are in similar
proportions as described for the other samples
The highest radionuclide concentration occurs in the smallest particle size fraction for each of
the samples tested except for sample MV2 (Tables 2-1 through 2-15). The -.002 mm
particles separated from sample MV2 were organic material that floated away from the host
material. For this sample the -.005/+.002 mm particles show the highest radionuclide
concentrations. The possible causes of these radionuclide concentrations based on these
samples are presented below.
1. Samples MV1 and MV6: The 947 pCi/g (MV1) and 85.4 pCi/g (MV6) of radium-228
in these samples is probably a result of (a) the solid calcium-thorium orthophosphate
compound produced in the thorium extraction process and (b) adsorbed thorium on
clay mineral surfaces. The presence of calcium-thorium orthophosphate is documented
in the larger size particles and would conceivably be present in the fine fractions as
well. None of the clay minerals identified by x-ray diffraction contain thorium, so
surface adsorption of the ion is the most reasonable explanation for the presence of
radioactivity in these fractions. It is also possible that monazite may contribute to the
total radioactivity, although it is not discemable on x-ray diffractograms because of
interferences from the spectra of the other clay minerals. Additional evaluation using
scanning electron microscope SEM/EDX measurements would help determine if
monazite is a possible source of the radioactivity.
6-17
-------
2. Samples MV3, MV8, MV9, and MV13: The 18.3 pCi/g (MV3), 24.0 pCi/g (MV8),
24.5 pCi/g (MV9), and 64.6 pCi/g (MV13) of radium-228 in the fines is probably
caused by (a) adsorption on the clay mineral surface and/or (b) crushed monazite to
such fine sizes for the reasons stated above. More extensive study, including
SEM/EDX investigation and linear density gradient separations, would help to
determine the nature of the radioactivity, as an adsorbate on a mineral surface or
firmly fixed material in a solid mineral crystal structure.
The source of the radioactivity in the fine fractions does not warrant a more extensive study if
soil washing is to be performed with a separation point somewhere in the coarse silt or fine
sand-size range, between .045 and .075 mm.
6.5 FEASIBILITY ANALYSIS OF SEPARATION PROCESSES BASED ON PHYSICAL
CHARACTERISTICS
The analysis of the experiments in this report are based on the results of the twenty samples
analyzed. The data from samples MV1 and MV6 appear to be inconsistent with those of the
remaining eighteen samples from the Maywood site.
The radioactive contamination on the Maywood site is predominantly thorium-232 in
equilibrium with its decay products. As a result, the thorium-232 concentrations in the soil
will be approximately equal to the radium-228 concentrations, which can be measured by
gamma spectroscopy. Similarly, the concentration of the uranium-238 decay series can be
estimated based on the gamma analysis for radium-226. Gamma spectroscopy is a
measurement technique that can be performed rapidly and inexpensively in the field to
provide information about the samples. A small number of samples would require analysis
by alpha spectrometry to verify the gamma spectroscopy results.
Radioactive contaminants in samples MIS1-MIS5, MV2-MV5, and MV7-MV15 are associated
with the -.045 mm particles. Separation of the fine particles isolates the majority of the
radioactive contaminants from the larger, less radioactive panicles whose average radionuclide
concentration is less than 5 pCi/g, thus reducing the volume of soil for disposal.
Several separation processes are available for reducing the volume of soils contaminated with
radioactivity.
6-18
-------
Common examples of the above are:
sieving (screening),
classification,
gravity separation, and
flotation.
All of these processes are used extensively in the mining industry, and are commonly
performed with soil slurried in water
Screening is the physical separation of particles on the basis of size. The separation is
achieved by passing the material through a uniformly perforated surface, or sieve. Particles
larger than the sieve openings arc retained on the surface as oversize or plus (+) material.
Particles smaller than the sieve openings pass through the sieve as undersize or minus (-)
material. Samples MIS1-MIS5, MV3-MV5, MV7-MV12, MV14, and MV15 were tested
using standard sieves. The results listed in Tables 2-3 through 2-5, 2-7 through 2-12, 2-14
through 2-16, 2-18, 2-20, 2-22, and 2-24 show that sieving can be successfully applied to the
Maywood soils with recovery of clean soil ranging from 60% for sample MV3 to 81% for
samples MV8 and MV10.
Classification is the separation of panicles according to their settling rate in a fluid, usually
water. Settling rate is a function of particle density and shape as well as particle size. The
hydroclassification tests performed in this study were designed to evaluate the effectiveness of
classification as a particle separation process for the Maywood soils. The results in Tables
2-2, 2-13, 2-17, 2-19, 2-21, 2-23, and 2-25 show that classification can be successfully
applied to the Maywood soils with recovery of clean soil ranging from 37% for sample MV2
to 79% for sample MV13. Figure 2 shows that similar results can be obtained using either
sieving or classification for the Maywood soils.
Gravity separation methods are based on the density of the particles. The only density
analysis performed as pan of this study was the heavy liquid separation for petrographic
analysis. The identification of monazite and zircon as the major source of radioactivity in the
sand size material suggests that a density separation of these minerals would reduce the
radioactivity of the sand size panicles. The difference between the densities of monazite and
zircon, which range from 3.9 and 5.5 g/cc, and the average density of the soil panicles,
6-19
-------
2.6 g/cc, is sufficient to effect separation using gravity processes. The radium-226
concentration in the sand size material for samples MV2-MV5, MV7-MV15, and MIS1-MIS5
was reduced to less than 5 pCi/g using sieving or classification techniques, so additional
processing is not required for these samples. Additional tests on the sand size particles from
samples MV1 and MV6 are needed to determine if gravity separation would reduce the
radionuclide concentrations for these samples to below the level of concern. Gamma analysis
of the sand fraction from MV1 after the heavy mineral separation showed that the radium-226
concentration was reduced from 65.5 pCi/g to 16.3 pCi/g, and that the radium-228
concentration was reduced from 269 pCi/g to 41.0 pCi/g (Table 8, MV1 light minerals,
-.25/+.15 mm).
Dewatering of soil slurries is an important step in a soil washing process. Several techniques
are available for dewatering slurries. Potential applications must be evaluated as pan of the
total soil washing process. The low percentage of clay sized particles (-0.002 mm) in the
Maywood soil (Tables 2-1, 2-2, 2-6, and 2-13) indicates that dewatering the Maywood soil
could be accomplished using any of several available processes.
Flotation processes separate particles by attaching air bubbles to certain particles and floating
them away from the remaining material. No tests were performed to evaluate this separation
technique. This process is most effective on panicles between 0.1 and 0.01 mm (EPA88), but
may be applicable to the -0.045 mm particles. Additional tests using (SEM/EDX) investigation
to identify the minerals in the -0.045 mm particles will indicate which panicles need to be
removed from the fine fraction. After the minerals have been identified, a suitable promoter
would have to be selected that would attach the air bubbles to the appropriate panicles.
Additional bench-scale tests will then be required to determine the feasibility of this technique
for the Maywood soils.
Magnetic separation using ferromagnetism will probably be ineffectual for the Maywood
soils. Magnetic separations work best on dry soils, while the previous techniques are more
effective using soil slurried with water. Monazite and zircon have magnetic susceptibilities in
the intermediate to low range (KR42). Additional screening tests or studies using
paramagnetism or electrostatic separation may suggest a separation process that can be
effectively applied to the Maywood soils.

-------
Information about particle liberation is required to determine the optimum washing process
for use with the Maywood soils. A vigorous wash was used for the analyses in this report,
further tests would be required to determine the attrition/scrubbing procedure that would be
most effective as pan of the volume reduction process.
Chemical extraction can also be considered for volume and/or radioactivity reduction of the
Maywood soils. If the goal of chemical extraction is to remove the monazite and zircon, the
residue left from a conventional sulfuric acid or sodium hydroxide extraction will produce
radium contaminated residues and may yield chemical waste products more hazardous than
the original soil (GR84). Samples MV1 and MV6 also contain calcium-thorium
orthophosphate precipitates. This material is probably insoluble residue left from a previous
extraction process and may prove difficult to further extract. Additional research using
different extractants may indicate a beneficial chemical extraction process.

7.0 Conclusions
Five borehole samples from the May wood FUSRAP site storage pile and fifteen samples from
various locations on the site were separated by particle size using wet sieving and
hydroclassification. The individual soils were analyzed for radioactivity with concentrations
above 5 pCi/g found in twelve of the samples and essentially background levels in the
remaining eight samples collected from the site.
All five borehole samples from the Maywood pile show that soil washing and panicle size
separation using sieving or hydroclassification techniques at .075 mm will produce an
oversize product containing as much as 70% of the original material with radium-226 and
radium-228 concentrations below 5 pCi/g as shown for sample MIS1 in Figure 2, and
thorium-232 and uranium-238 concentrations below 5 pCi/g as shown for sample MIS2 in
Table 3-7. Thirteen of the fifteen soil samples from the site show that a separation at
.045 mm can be performed and the oversize product will contain as much as 80% of the
original material with radium-226 and radium-228 concentrations below 5 pCi/g, as shown for
sample MV13 in Table 3-6.
The two remaining samples, MV1 and MV6, contained elevated levels of radium in all
particle size fractions after soil washing and size separation tests were performed. Although
the radioactivity was concentrated in the smaller size fractions, radionuclide concentrations
greater than 5 pCi/g were retained on the larger particles.

The Maywood, New Jersey, FUSRAP site comprises the DOE owned Maywood Interim
Storage Site (MISS) and 82 vicinity properties. There is also an interim waste storage pile on
the MISS which contains approximately 35000 yd3 of contaminated soil removed from
vicinity properties in remedial operations. Of the twenty Maywood soil samples discussed in
this report, five were characterized for potential treatability by NAREL in 1991. These were
all taken from the MISS pile at locations shown in Figure 1, and are designated MIS1-MIS5.
The results of the 1991 study indicate that a 65% volume reduction might be attainable for
the MISS pile soils using particle separation treatment, and a decision was made to conduct
further characterization studies at NAREL with a wider range of Maywood samples.
At the time the samples were collected in early 1992, there were more than Five hundred
55-gallon drums of drill cuttings from Maywood soil sampling boreholes in storage at the
MISS and samples for the Maywood (NAREL) characterization study were selected from
these to represent a range of contaminant levels, soil types, and locations on properties with
the largest volumes of contaminated soil. Fifteen samples were selected and are designated
MV1-MV15 for this report. Sample MV10 is a duplicate of MV4 and MV11 is a duplicate
of MV7 although these samples were not identified as duplicates when provided to NAREL.
Most of the drums contained soil from a number of boreholes so that there was a range of
commingled contaminant concentrations vertically within boreholes, and laterally between
boreholes at different locations. Table A lists sample numbers, BN1 (Bechtel) storage drum
numbers, the Maywood property name, and borehole numbers from which the drill cuttings in
the sampled drum were obtained. The coordinates in Table A are the easting and northing
survey locations for each borehole represented in the samples. The locations from which the
fifteen samples were collected are shown as numbered squares on the maps in Figure 9
through Figure 13. Drill cuttings from some of the boreholes were placed in more than one
storage drum and these are shown by multiple numbers at these locations. No locations are
marked for samples MV10 and MV11 since these are duplicates of MV4 and MV7.
The range of values for thorium-232, radium-226, and uranium-238 are the laboratory
radionuclide analysis results for the soil core samples collected at the indicated borehole
locations. The complete analytical data are listed in the Maywood Remedial Investigation
Report, and in the numerous individual survey reports for the Maywood properties, which are
all pan of the Administrative Record for the site. Many of the analytical results were near
background levels, and therefore, for most of the samples, the NAREL whole soil gamma
spectroscopy results for radium-226 and radium-228 are less than the radium-226 and
