                                   ABSTRACT









    This report describes soil profiles of the surface soils in mounds in two




areas located on the Test Range Complex, Nye County, Nevada.  Both areas have




been the sites of aboveground nuclear safety tests.  These areas are




contaminated with plutonium and are the object of investigations regarding the




movement of plutonium in the environment.









    Most of the surface soils in the two plutonium-contaminated sites of the




Test Range Complex have gravelly texture and are typically classified as




gravelly sandy loam.  Most of the land sampled is either floodplain or




alluvial fan with deep soils having well-developed profiles and platy or




subangular blocky structure.









    In the areas sampled, the wind has a dominant influence on the surface




texture of the soil.  It has moved the fine-textured soils around individual




plants or plant clumps, thus leaving the coarse soil particles in low areas




between the plants.









    All of the soils are alkaline and range in pH from 7 to 9.  The color of




the surface soil ranges from light gray to very pale brown dry and from brown




to dark grayish brown moist.  Most of the soils are potentially agricultural




if water were available.  The soil drainage is well to very well drained.
                                    ii

-------
    The vegetation is classified as high desert grass and shrubs.  The grass




and shrubs are predominately winter fat (Eurotia lanata), fourwing saltbush




(Atriplex canescens), shadscale (Atriplex confertifolia), bud sagebrush




(Artemisia spinescens). galleta grass (Hilaria jamesii). and Indian ricegrass




(Oryzopsis hymenoides).









    Domestic livestock prefer the above vegetation to any other that grows on




the desert range.  Because a large portion of the land sampled could be




cultivated for crops  or is potentially good winter range, these findings




should be considered  in any '"cleanup" decision.

                              I.  INTRODUCTION
    In the early stages  of  the Nevada Applied Ecology Group (NAEG) soil




sampling program, a plutonium inventory was started for the various areas on




the Nevada Test Range  Complex in which soil samples had been taken generally




in the open spaces between  the desert plants.









    It was recently established by Tamura (1975) that the plutonium activity




in soils at the Test Range  Complex is associated with different soil particle




sizes of which the coarse silt fraction (53 to 20 micrometers) contained the




highest percentage of  activity (about 65%).  These particle sizes are readily




subjected to movement  by wind and collect at the base of plants, developing




into hummocks around the desert vegetation.









    Because it does get  windy on the Test Range Complex, fine soil particles




can accumulate around  the plant by wind action.  Essington and Fowler (1976)




reported that plutonium  had migrated even further down in the soil they




sampled in 1973 than it  had in soil sampled from the same area 15 years




earlier.  Therefore, the mounding of plutonium-contaminated soil and the




observed ability of plutonium to migrate to deeper layers of the soil with




time together pose a situation of greater exposure to the roots and probably a




higher uptake of plutonium by the plant.

-------
    The information reported by Tamura (1975) and Essington and Fowler (1976)

points to the importance and necessity of a soil-mound sampling program.

Before such a program could be implemented, the soil mounds around the plants

needed to be characterized and their profiles described.  The study reported

here was undertaken to describe the soil profiles of the mounds.




    Data from the sampling of the soils and descriptions of their physical

properties provide guidance to investigators as to those soil characteristics

which could have an impact on the movement of plutonium through the soil and

on the uptake of plutonium by plants.




    In a previous study (Leavitt, 1974), 127 sites were sampled to determine

soil type of the Clean Slate 3 area and Area 13 on the Test Range Complex*.

This work was done at the request of the NAEG, U.S. Department of Energy

(DOE), under the requirements of the National Environmental Policy Act of

1969.  One of NAEG's goals is to develop techniques for the cleanup or

treatment of actinide-contaminated soils.  This mound study is one of several

studies needed by the Group to accomplish this goal.




    The soil samples were taken from the mounds of Area 13 and the Clean Slate

3 area and were described as to their texture, structure, pH, and

permeability.  The soil descriptions provide a basis for other researchers to
*Test Range Complex includes the Tonopah Test Range (TTR), Nuclear Rocket
 Development Station (NRDS), Nevada Test Site (NTS) , and Nellis Air Force
 Range (NAFR).

-------
determine the plutonium activity that is associated with the different soil




fractions found in the mounds around native plants.









    This report covers three different types of soil and vegetation sampling




sites.  They are soils and shrubs, soils and grass, and animal mounds or




burrows.

-------
                           II.   AREA DESCRIPTIONS
    This work covered areas in the south-central and eastern parts of Nye




County in southern Nevada (Figure 1).   These areas are semiarid with




precipitation ranging from 10 to 30 centimeters (4 to 12 inches) (Maxey and




Jameson, 1948).   All of these areas provide only limited grazing for




livestock; however, about three-fourths of the acreage sampled would be




classified as potential agricultural land if water were available.









CLEAN SLATE 3 AREA









    The Clean Slate 3 area, located in Area 52, was sampled on the Tonopah




Test Range.  The Clean Slate 3 area, in what is commonly known as Cactus Flat,




is a desert grassland site with an elevation of about 1,650 meters (5,400




feet) along the floodplain of Cactus Flat.  Most of the soils sampled in this




area are of cropland quality.  The vegetation there is dominated by galleta




grass (Hilaria jamesii) and Indian ricegrass (Oryzopsis hymenoides), which




would make this  area very good desert  range for livestock.  The soils and




vegetation found here are similar to those in Area 13 of the NTS.

AREA 13









    Area 13 is in the northeastern corner of the Test Range Complex.  It is




in the bottom of a wide alluvial valley about 1,317 meters (4,500 feet) in




elevation.  It is bounded on the east by the Groom Range and on the west by




the Belted Range.  Most of its land is classified as potential agricultural




cropland.  Its soils and vegetation are similar to those in the Clean Slate 3




area of the Tonopah Test Range.  The soils are deep and very productive.  NAEG




investigators have conducted various types of research studies in this area




ranging from greenhouse soil and plant experiments to large animal grazing




studies (Au et al., 1976, 1977; Smith, 1976).  The locations in Area 13 from




which soil samples were taken are shown in Figure 2.

                           III.   PROFILE SAMPLING
    Soil and vegetation samples were taken at each sampling site by Reynolds




Electrical and Engineering Company, Inc.  personnel (Essington and Fowler,




1976).  The samples were taken at random in a systematic manner according to




plot, quadrant, quadrate, mound, and whether the mound had a single plant or a




complex of two or more plants.  Sketches of the different types of soil mounds




sampled are presented in Figure 3.  A very shallow pit was dug to a depth of




5 cm at each sampling site, and the soil profile was determined by visual




inspection.  All characterizations of the soil were performed on site at the




time of sampling.









    The field sampling procedure was to cut or saw the aboveground vegetation




level with the top of the mound without disturbing the mound soil.  Each mound




was then photographed with a stereo camera at an angle perpendicular to the




vertical axis of the mound at a distance just far enough away to include the




whole mound and part of the desert pavement surrounding the mound.  From three




to six radials were selected for profile sampling depending on the uniformity




of the mound.  Samples were collected by Reynolds Electrical and Engineering




Company, Inc. personnel using a technique that prevents cross-contamination of




samples (Essington and Fowler, 1976).  Briefly, this was accomplished using

-------
a specially constructed scoop which removed a sample 10 cm x 1 cm and 2-1/2 cm




deep.  A second 2-1/2-cm deep sample was removed separately following the




first so that a profile was obtained to a depth of 5 cm.  Samples from each




mound were taken as close to the vegetation clump as practical.

                IV.   SOIL PROFILE CHARACTERIZATION PROCEDURES
    Soil colors were determined by comparing the sample with the Munsell Soil




Color Chart (Munsell Color Company, Inc.,  1954).  The method requires visual




matching of the soil sample to an appropriate color chip.  The standardized




color chips include designators for hue,  value,  and chroma.  Hue is the




dominant spectral color.  Value refers to the relative lightness of color and




is a function of the total amount of reflected light.  Chroma, or the




saturation, is the relative purity or strength of the spectral color and




increases with decreasing grayness.  Colors are  for air-dried soil unless




otherwise noted.









    Soil structure, pH, and effervescence were determined by procedures




described by the U.S. Soil Conservation Service  (1951).  Soil texture was




determined by rolling the moistened soil  sample  between the thumb and index




finger.  Soil structure was determined visually  from the aggregability of the




primary soil particles into compound particles.   Soil pH was determined by




placing enough indicator dye solution to  cover the soil sample in the spot




plate.  Cresol red was used between pH 7.2 and 8.8, and thymol blue was used




between pH 8.0 and 9.6.









    Effervescence was determined by adding a few drops of 0.1N HC1 to the soil




as an indication of the occurrence of certain salts in various crystalline




                                    12

-------
forms.  The effervescent reaction was correlated to the relative




concentrations of carbonates of calcium, magnesium, and sodium present in the




soil.

-------
                         V.  RESULTS AND DISCUSSION
    Most of the surface soils in the two plutonium-contaminated sites of the




Test Range Complex have gravelly texture and are typically classified as




gravelly sandy loam.  The majority of land sampled is either floodplain or




alluvial fan with deep soils having well-developed profiles and platy or




subangular blocky structure.









    In the areas sampled, the wind has a dominant influence on the surface




texture of the soil.  It has moved the fine-textured soils around individual




plants or plant clumps, thus leaving the coarse soil particles in low areas




between the plants.  It was found that the size of the soil mound increased




with the size of the plant because of the plant biomass acting as a barrier




for the deposition of soil by the wind.









    It has been established by Tamura (1975) that the highest plutonium




activity in soils at the NTS is associated with the coarse silt particle size




fraction (53 to 20 micrometers).  This particle size is easily moved by the




wind.










    In the soil profile mound study, it was generally found that the soil




around the brush was finer textured than that found in the animal diggings.
                                     14

-------
This difference is due to the burrowing and continuous foraging habits of the




animals which cause a mixing of the coarse and fine soils resulting in a




coarser soil texture found at the animal mounds.









    All of the soils are alkaline and range in pH from 7 to 9.  The color of




the surface soil ranges from light gray to very pale brown dry and from brown




to dark grayish brown moist.  Most of the soils are potentially agricultural




if water were available.  The soil drainage is well to very well drained.









    The vegetation is classified as high desert grass and shrubs.  The grass




and shrubs are predominately winter fat (Eurotia lanata), fourwing saltbush




(Atriplex canescens), shadscale (Atriplex confertifolia), bud sagebrush




(Artemisia spinescens), galleta grass (Hilaria jamesii), and Indian ricegrass




(Oryzopsis hymenoides).  The scientific and common names of the vegetation




occurring in the mound study areas are given in Table 1.









    Domestic livestock prefer the above vegetation to any other that grows on




the desert range.  Because a large portion of the land sampled could be




cultivated for crops or is potentially good winter range, these findings




should be considered in any '"cleanup" decision.

AI horizon.  -  This is a surface mineral soil horizon, usually dark in
color, which has a relatively high content of organic matter mixed with
mineral matter.
^2 horizon.  -  This surface or subsurface horizon, usually lighter in
color than the underlying horizon, has lost clay minerals, iron, or aluminum,
or all three, with the resultant concentration of the more resistant minerals.
It is a horizon of eluviation - of leaching of materials out in solution and
suspension.
