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.

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. ------- DUCKWATER CURRANT MAINT. STA.-fc CURRANT ROUND MTN. GEYSER MAINT. STA. BLUE JAY MAINT. STA.

The areas sampled on the Nevada Test Range Complex. ------- 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. ------- Area 13 400 numbers represent soil series. Lettered numbers represent sampling sites.

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. ------- 1. GRASS CLUMP 2. SHRUB (SINGLE) 3. SHRUB COMPLEX I- 2cm 3-10 cm 5-25 cm 4.

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. 13 ------- 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. 15 ------- TABLE 1.
