Some factors affecting their development and longevity","docAbstract":"<p><span>Perched water tables on hillsides located on the western border of the Willamette Valley in Oregon in some cases have the potential to transport pollutants from either domestic or agricultural sources downslope to streams, ponds, or reservoirs, resulting in the deterioration of the quality of these waters. In this paper, some factors responsible for the development and longevity of these potentially problem-causing perched water tables on three hillsides were examined. Analyses of hydraulic conductivity data and the relationships between rainfall, soil water pressure potential, and time suggest that permeable rock below 110 cm rather than clayey B horizons is mainly responsible for the development of perched water tables on upper convex slope positions on two of these hillsides. The data also suggest that subsurface flow from the upper convex regions contributed significant amounts of water to the lower convex slope positions. Further, perched water tables developed more rapidly, to a greater extent, and lasted longer in upper horizons of a lower concave region of slope where a shallow perched water table was already present at the onset of rainfall. Finally, perched water tables did not develop in the upper horizons on a third hillside that had no impermeable regions in the soil or upper rock mantle.</span></p>","language":"English","publisher":"Wiley","doi":"10.2136/sssaj1982.03615995004600040030x","issn":"03615995","usgsCitation":"Hammermeister, D., Kling, G., and Vomocil, J., 1982, Perched water tables on hillsides in western Oregon: I.

Preferential downslope movement of water and anions","docAbstract":"<p><span>Perched water tables on hillsides in western Oregon potentially provide a means by which pollutants from agricultural and domestic sources may enter surface waters and consequently degrade the quality of these waters. This paper reports the results of experiments which were carried out to investigate the flow of solutes and water from buried line sources in and above perched water tables on three different hillsides in western Oregon. In the saturated soil and rock mantles of two hillsides, evidence suggests that water and solutes flow preferentially through large continuous voids. The evidence includes the very high maximum rate of anion movement downslope, the failure of pore velocities calculated from Darcy's Law to predict the rate and direction of anion movement, the short time before high levels of anions are detected downslope, and the spatial variability in the maximum rates of anion movement over the depth and width of sites. On the third hillside, tracer anion movement and soil water pressure measurements indicate that preferential flow occurs through large continuous pores during heavy rainfall while the surrounding soil and rock mantle remains unsaturated. Finally, experiments with Rodamine WT dye show that a variety of continuous voids of different origins and sizes conduct water and solutes preferentially in the soil and upper regions of rock on these hillsides.</span></p>","language":"English","publisher":"Wiley","doi":"10.2136/sssaj1982.03615995004600040031x","issn":"03615995","usgsCitation":"Hammermeister, D., Kling, G., and Vomocil, J., 1982, Perched water tables on hillsides in western Oregon: II.

Identification of chemicals implicated in these die-offs is difficult and sometimes conclusions are solely circumstantial. However, when marked depression (inhibition) of brain ChE activity accompanies organophosphorus or carbamate residues in body tissues or ingesta, cause-effect diagnosis is enhanced. To achieve this end, normal brain ChE activity is estimated for controls of the affected species and then die-off specimens are individually evaluated for evidence of ChE inhibition. This approach to evaluation of antiChE poisoning may also be used to monitor exposure of vertebrates to field application of organophosphorus or carbamate pesticides. Problems associated with this kind of evaluation, and the main topic of this report, include variability of brain ChE activity among species, postmortem influences of ambient conditions (storage or field) on ChE activity, and differential patterns of ChE activity when inhibited by organophosphorus or carbamate compounds. Other topics discussed are the ChE assay procedure, example case reports and interpretation, and research needed for improving the diagnostic utility of ChE activity in a field situation.

Compared with tundrius, anatum is larger and darker, and the white auricular area is less extensive in proportion to the black malar stripe (White 1968a). This paper presents morphological information from two migrant populations. Also, measurements are compared with F. p. tundrius described by White (1968a,b), although shrinkage in study skins (the source of White's measurements) was recently documented (Fjelds• 1980) and confounds direct comparison. </p>","language":"English","usgsCitation":"Henny, C.J., and Clark, W., 1982, Measurements of fall migrant peregrine falcons from Texas and New Jersey: Journal of Field

Metals in earthworms (</span><i>Lumbricidae</i><span>) from agricultural fields amended with sewage sludge and from experimental plots were examined to determine if earthworms are important in transferring metals in soil to wildlife. Earthworms from four sites amended with sludge contained significantly (</span><i>P</i><span>&nbsp;&lt; 0.05) more Cd (12 times), Cu (2.4 times), Zn (2.0 times), and Pb (1.2 times) than did earthworms from control sites, but the concentrations detected varied greatly and depended on the particular sludge application. Generally, Cd and Zn were concentrated by earthworms relative to soil, and Cu, Pb, and Ni were not concentrated. Concentrations of Cd, Zn, Cu, and Pb in earthworms were correlated (</span><i>P</i><span>&nbsp;&lt; 0.05) with those in soil. The ratio of the concentration of metals in earthworms to the concentration of metals in soil tended to be lower in contaminated soil than in clean soil. Concentrations of Cd as high as 100 ppm (dry wt) were detected in earthworms from soil containing only 2 ppm Cd. These concentrations are considered hazardous to wildlife that eat worms. Liming soil decreased Cd concentrations in earthworms slightly (</span><i>P</i><span>&nbsp;&lt; 0.05) but had no discernible effect on concentrations of the other metals studied. High Zn concentrations in soil substantially reduced Cd concentrations in earthworms.</span></p>","largerWorkTitle":"","language":"English","publisher":"Wiley","doi":"10.2134/jeq1982.00472425001100030012x","usgsCitation":"Beyer, W., Chaney, R.L., and Mulhern, B., 1982,

The toxicity of Prudhoe Bay crude oil and No. 2 fuel oil to embryos of mallard ducks (Anas platyrhynchos) decreased only after 3 weeks and 2 weeks of weathering on a large container of fresh water (SZARO et al. 1980). Ten microliters (uL) of 4 week-old Libyan crude oil caused a significant increase in mortality among embryos of Louisiana herons (Hydranassa tricolor) but the same amount of fresh oil did not cause a significant increase in mortality. However, embryos of laughing gulls (Larus atricilla) were not significantly affected by I0 uL of 4 or 8 week-old weathered Libyan crude oil nor i0 UL of fresh oil (MACKO&amp; KING 1980). Crude ell (i0 uL) recovered from the water surface (age unknown, but presumably slightly weathered) near the IXTOC-I oil spill site in the Gulf of Mexico did not significantly reduce the survival of mallard embryos by day 18 of incubation (D.

The most important pathfinder for regional hydrogeochemical surveys is sulfate which reflects the associated pyrite mineralization. Because of increased mobility due to intense chemical weathering and the low pH environment, dissolved copper can also be used as a pathfinder for regional surveys and has the advantage of distinguishing barren pyrite from pyrite associated with copper mineralization. For follow-up surveys, the most important pathfinders are copper, sulfate, pH, zinc, and fluoride. High concentrations of dissolved copper and moderate concentrations of sulfate is a diagnostic indication of nearby sources of copper minerals. </p><p>An understanding of the geochemical processes

Results are integrated with previous geologic and geochronologic data for the area to produce a model for uranium mobility that may be used to explore for uranium deposits in similar geologic settings.</span></p><p><span>Uraniferous opal occurs as replacements of diatomite, or silicic air-fall ash layers in tuffaceous lakebeds of the Virgin Valley Formation (Miocene) of Merriam (1907). Fission-track radiography shows uranium to be homogeneously dispersed throughout the opal structure, suggesting coprecipitation of dissolved uranium and silica gel. Fluid inclusions preserved within opal replacements of diatomite have homogenization temperatures in the epithermal range and are of low salinity. Four samples of opal from one locality all have U-Pb apparent ages which suggest uraniferous opal precipitation in late Pliocene time. These ages correspond to a period of local, normal faulting, and highangle faults may have served as vertical conduits for transport of deep, thermalized ground water to shallower levels. Lateral migration of rising solutions occurred at intersections of faults with permeable strata. Silica and some uranium were dissolved from silica-rich host strata of 5–20 ppm original uranium content and reprecipitated as the solutions cooled. The model predicts that in similar geologic settings, ore-grade concentrations of uranium will occur in permeable strata that intersect high-angle faults and that contain uranium source rocks as well as efficient reductant traps for uranium. In the absence of sufficient quantities of reductant materials, uranium will be flushed from the system or will accumulate in low-grade disseminated hosts such as uraniferous opal.</span></p>","language":"English","publisher":"Elsevier","doi":"10.1016/0375-6742(82)90010-3","usgsCitation":"Zielinski, R.A., 1982, Uraniferous opal, Virgin Valley, Nevada: Conditions of

The oldest rocks exposed are a very thick sequence of volcanic flow rocks of mostly felsic to intermediate composition interbedded with volcaniclastic and sedimentary rocks. The layered rocks reflect a less primitive state of crustal evolution than has generally been ascribed to this sequence. These rocks were deposited upon an emerging basement of mafic to intermediate composition, and the sedimentary materials reflect a source terrane of mostly intermediate to felsic character.</p><p>The layered rocks were subjected to three separate episodes of compressional deformation, each followed by appreciable talc-alkalic plutonism.

Organic carbon content averages about 0.42 weight percent in reduced rock and correlates postively with sulfur content. Pyrite is the dominant iron disulfide (FeS&nbsp;</span><sub>2</sub><span>&nbsp;) mineral in most of the ore zone and throughout a surrounding zone of reduced barren ground, and it is commonly associated with organic debris. Marcasite is sparse except in ore adjacent to the altered tongue in one core and locally in mineralized lignite. Sulfur isotopic compositions (delta&nbsp;</span><sup>34</sup><span>&nbsp;S) of FeS&nbsp;</span><sub>2</sub><span>&nbsp;minerals range broadly from -1 to -34 per mil; the lightest delta&nbsp;</span><sup>34</sup><span>&nbsp;S values (less than -20 per mil) were measured in samples from mineralized lignite and from the nose of the ore roll. Petrographic and geochemical characteristics of the Panna Maria deposit contrast greatly with those of three other south Texas roll-type uranium deposits (the Benavides, Felder, and Lamprecht deposits), which are devoid of organic carbon and which contain more sulfide than does the Panna Maria. These three deposits are characterized by abundant isotopically light ore-stage marcasite and by isotopically heavy preore (in the Benavides) or postore (in the Felder and Lamprecht) pyrite. We have concluded previously that sulfide-bearing fault-leaked solutions from underlying hydrocarbon accumulations were important in the formation of the Benavides, Felder, and Lamprecht deposits.

Soil matric potentials were measured and unsaturated hydraulic conductivities were calculated over a range of matric potentials at 2°, 25°, and 45° ± 0.5°C. In addition, water retention characteristics (to −100 kPa) were measured at these same temperatures for both soils. In this paper, the calculated results are compared to an equation that relates unsaturated conductivity to the intrinsic permeability, the relative permeability, and the viscosity of water. The equation considers viscosity to be the only parameter that changes with temperature. The results show a much greater temperature dependence in the unsaturated conductivity than would be predicted by this equation. The results indicate that the relative permeability may be a function of temperature. The temperature dependence of the soil water matric potential, surface tension, and diffuse double-layer thickness are discussed in terms of their possible interaction with the unsaturated conductivity values obtained. A case is presented for further study to isolate these temperature-sensitive parameters as well as additional parameters related to fluid flow path changes with temperature.</span></p>","language":"English","publisher":"Wiley","doi":"10.2136/sssaj1982.03615995004600030005x","issn":"03615995","usgsCitation":"Constantz, J., 1982, Temperature dependence of unsaturated hydraulic conductivity of two soils: Soil Science Society of America Journal, v. 46, no. 3, p. 466-470, https://doi.org/10.2136/sssaj1982.03615995004600030005x.","productDescription":"5 p.","startPage":"466","endPage":"470","costCenters":[],"links":[{"id":221189,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"46","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505ba4c3e4b08c986b32057c","contributors":{"authors":[{"text":"Constantz, Jim","contributorId":66338,"corporation":false,"usgs":true,"family":"Constantz","given":"Jim","affiliations":[],"preferred":false,"id":361583,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
