Differentiation of Colletotrichum species responsible for anthracnose of strawberry by arbitrarily primed PCR
S. Freeman, R. J. Rodriguez
1995, Mycological Research (99) 501-504
A collection of 39 isolates of Colletotrichum acutatum, C. fragariae and C. gloeosporioides, which cause anthracnose on strawberry, was grouped into species based on the arbitrarily primed polymerase chain reaction (ap-PCR). All isolates used had previously been identified according to classical taxonomic morphology. Ap-PCR amplification of genomic DNA using four...
Acid Rain

1995, Conference Paper, Energy and the environment - Application of geosciences to decision-making (Circular 1108)
Although acid rain is fading as a political issue in the United States and funds for research in this area have largely disappeared, the acidity of rain in the Eastern United States has not changed significantly over the last decade, and it continues to be a serious environmental problem. Acid...
Seasonal cycles of dissolved constituents in streamwater in two forested catchments in the mid-Atlantic region of the eastern U.S.A.
Karen C. Rice, Owen P. Bricker
1995, Journal of Hydrology (170) 137-158
Streamwater discharge and chemistry of two small catchments on Catoctin Mountain in north-central Maryland have been monitored since 1982. Repetitive seasonal cycles in stream-water chemistry have been observed each year, along with seasonal cycles in the volume of stream discharge and in groundwater levels. The hypothesis that the observed streamwater...

Particle-tracking analysis of flow paths and travel times within the capture areas of well fields in Salt Lake Valley, Utah
P. M. Lambert
1995, Technical Publication 110-C
A particle-tracking analysis was done to estimate capture zones for selected public-supply wells in Salt Lake Valley. Twenty-five- and 50-year capture zones were estimated using a regional, finite-difference, ground-water flow model in conjunction with a particle-tracking program. Three sets of wells currently discharging ground water of adequate quality for public...
Chemical composition of ground water, hydrologic properties of basin-fill material, and ground-water movement in Salt Lake Valley, Utah
Susan A. Thiros
1995, Technical Publication 110-A
The chemical composition and movement of ground water and hydrologic properties of the basin‑fill material were studied to better under‑ stand the flow system in Salt Lake Valley, Utah. Recharge sources and water‑rock interactions influence the water chemistry in the principal and shallow unconfined aquifers. Chloride concentration in water from...

This is the thirty-second in a series of annual reports that describe ground-water conditions in Utah. Reports in this series, published cooperatively by the U.S. Geological Survey and the Utah Department of Natural Resources, Division of Water Resources, provide data to enable interested parties to keep abreast of changing ground-water...
Numerical simulation of ground-water flow in basin-fill material in Salt Lake Valley, Utah
P. M. Lambert
1995, Technical Publication 110-B
A three-dimensional, finite-difference, numerical model was developed to simulate ground-water flow in the basin-fill material in Salt Lake Valley, Utah. The model was calibrated to steady-state and transient-state conditions. The steady-state simulation was developed and calibrated using hydrologic data defining average conditions for 1968. The transient-state simulation was developed and...

Mark P. Ort, Susan E. Finger, John R. Jones
1995, Environmental Pollution (90) 105-110
Effects of crude oil on survival and behavior of the mayfly Hexagenia bilineata were evaluated in laboratory studies. Mayfly nymphs were exposed to the water soluble and oil residue fractions of crude oil. Mayfly survival was not reduced by a 96-h exposure to either the water soluble...
Hydrology of the Sevier-Sigurd ground-water basin and other ground-water basins, central Sevier Valley, Utah.
P. M. Lambert, J. L. Mason, R. W Puchta
1995, Technical Publication 103
The hydrologic system in the central Sevier Valley, and more specifically the Sevier-Sigurd basin, is a complex system in which surface- and ground-water systems are interrelated. Seepage from an extensive irrigation system is the primary source of recharge to the basin-fill aquifer in the Sevier-Sigurd basin.Water-quality data indicate that inflow...

L.E. Brooks, Bernard J. Stolp
1995, Technical Publication 111
The ground-water resources of southern Utah and Goshen Valleys were assessed from 1988 to 1993 to determine the effects that additional ground-water withdrawals would have on water levels, surface water, and water quality.

Jimmie D. Petty, James N. Huckins, D.B. Martin, T.G. Adornato
1995, Chemosphere (30) 1891-1903
The semipermeable membrane device (SPMD), consisting of a neutral lipid (triolein) enclosed in polyethylene layflat tubing, is very effective in sequestering bioavailable organochlorine (OC) pesticides in the environment. We used SPMDs to sequester OC pesticide residues in streams receiving irrigation drainwater and found toxaphene, the DDT complex, dieldrin, and endrin....
Water budget and simulation of one-dimensional unsaturated flow for a flood- and a sprinkler-irrigated field near Milford, Utah
David D. Susong
1995, Technical Publication 109
Ground-water recharge to basin-fill aquifers from unconsumed irrigation water in the western United States is being reduced as irrigators convert to more efficient irrigation systems. In some areas, these changes in irrigation methods may be contributing to ground-water-level declines and reducing the quantity of water available to downgradient users. The...
