Correlation of regional geohydrologic units to geological formations in southern Missouri

As part of the U.S Geological Survey's Regional Aquifer-System Analysis Program, geologic formations in southern Missouri (index map) were grouped into eight regional geohydrologic units on the basis of relative rock permeability and well yields (imes and Emmett, in press). Geohydrologic unit boundaries do not necessarily coincide with geologic unit boundaries or geologic time lines, but are determined by regional hydrologic properties, which may vary from one area to another. The geologic formaitons were grouped into the geohydrologic units to determine the hydrologic characteristics of regional aquifer systems and associated regional confining units in parts of Arkansas, Kansas,Missouri, and Oklahoma. This report presents a correlation of the regional geohydrologic units to corresponding geologic formations in southern Missouri. Included in the report is a brief geologic history of southern Missouri.

Water resources data, Missouri, water year 1990

The U.S. Geological Survey, in cooperation with local, State, and Federal agencies and organizations, obtains a large quantity of data pertaining to the water resources of Missouri each water year (October 1 to September 30). These data, accumulated during many water years, constitute a valuable data base for developing an improved understanding of the water resources of Missouri. To make these data readily available to interested parties outside the U.S. Geological Survey, the data are published annually in this report series, entitled "WATER RESOURCES DATA FOR MISSOURI." This volume contains records for water discharge at 107 gaging stations; stage and contents at 11 lakes and reservoirs; water level records for 58 ground-water monitoring wells; water quality at 43 sampling stations (including 2 lakes); and data for 13 crest-stage stations.

Mid-continent earthquake zones; lessons from New Madrid, Missouri

Many seismically active regions occur throughout the world as concentrated zones surrounded by the relatively stable crust of shields or platforms. Examples occur in central and eastern North America, northeastern Brazil, Australia, Norway, Svalbard, Greenland, and other places. Some of these zones, such as those at New Madrid, Missouri, and in the St. Lawrence Valley on the Canadian border, extend over relatively large areas and are marked by a high level of seismicity. Others, such as that near Anna Ohio, are smaller, and the level of activity is lower. Some zones are occasinoally sites for major earthquakes which, if they are in populated regions, can cause widespread destrucion and loss of life.

Toxicity of municipal wastewater effluents contaminated by pentachlorophenol in southwest Missouri

Toxicity of effluents from two sewage treatment plants in Joplin, Missouri, was tested using Ceriodaphnia dubia and Pimephales promelas . No test organisms survived in effluents from either plant, in effluents diluted with water from Turkey Creek (the receiving stream), or in water from Turkey Creek. Mortality was complete in all but the most dilute treatments of effluents, in which reconstituted water was used as the diluent. High concentrations of pentachlorophenol (130–970 μg liter −1 ) in effluents and the receiving stream likely caused mortality during the 7-day tests. Detectable concentrations of other phenolic compounds indicated the presence in Turkey Creek of other toxic by-products of pentachlorophenol manufacture. This study demonstrated the utility of biological tests of whole effluents to determine toxicity of wastewater effluents.

Relationships between live tree diameter and cavity abundance in a Missouri oak-hickory forest

We quantified relationships between mean dbh of live, dominant and codominant trees, and cavity abundance in an oak-hickory forest in southeast Missouri. Inspection of 3,981 trees >12.7 cm dbh in 107 0.1-ha plots indicated that cavities occurred in 19.9% of all trees. White oak, black oak, scarlet oak, and hickories composed 97% of the sample. Black oak contained the greatest number and frequency of cavities; white oak had the fewest cavities. In general, the proportion of trees with cavities increased as dbh increased, but mean tree dbh per plot explained little of the observed variance in cavity abundance. Correlations between tree diameter and cavity abundance were poor because of the wide variety of factors that affect cavity development in living trees. Differences in cavity occurrence among tree species suggest that black and scarlet oaks should be selected over hickories and white oak when managing for cavity trees.

Delineation of flooding within the Ozark National Scenic Riverways in southeastern Missouri - Round Spring and Powder Mill

This is the second report in a series of U.S. Geological Survey Hydrologic Investigations Atlases to further supplement the National Park Service general management and development concept plan for the Ozark National Scenic Riverways (National Park Service, 1981) in southeastern Missouri (fig. 1). The technical basis on which the National Park Service can develop flood-management plans for use in evaluating their existing or future developments at Akers and Alley Spring recreational areas is given in Hydrologic Investigations Atlas HA-712-A (Alexander, in press). The Ozark National Scenic Riverways, administered by the National Park Service, is an extensively used recreational area where approximately 2 million visitors per year (M.E. Hunter, National Park Service, oral commun., 1985) participate in a wide range of river-use and land-based activities. Visitor areas along the 134-mi (mile) reach of the Current River and its principal tributary, Jacks Fork, range from highly-developed areas mostly along the upper Current River to primitive camping areas and river accesses along the Jacks Fork and downstream reach of the Current River. Most facilities at these developments are in or near flood-prone areas. Therefore, because of visitor safety, a major consideration of the National Park Service is the implementation of a flood-warning system.

Pesticide contamination of endangered gray bats and their food base in Boone County, Missouri, 1982

Gray bat guano from Devil's Icebox and Hunters Caves contained dieldrin at levels previously associated with gray bat mortality. Two of four gray bats found dead in Holton Cave had lethal brain concentrations of dieldrin. Twenty-five of 28 (86%) insect samples from bat foraging areas contained measurable dieldrin, heptachlor epoxide or both. Beetle samples were most heavily contaminated containing up to 2.2 ppm and 1.1 ppm heptachlor epoxide. The addition of Holton Cave brings to five the number of Missouri caves where gray bats have died of food chain pesticide poisoning.

Structure contour maps on the base of Mississippian strata and the top of upper Cambrian strata, Springfield 1 degree by 2 degrees Quadrangle, Missouri

This publication is part of a folio of maps of the Springfield 10° × 20° quadrangle, Missouri, prepared under the Conterminous United States Mineral Assessment Program of the U.S. Geological Survey. Other publications in this folio to date include U.S. Geological Survey Miscellaneous Field Studies Maps MF-1830-A through F (Erickson and others, 1985; Whitfield, 1986; Wharton, 1987; Middendorf and others, 1987; Kisvarsanyi, 1987; Rueff, 1987); U.

Subsurface geology of Paleozoic, Mesozoic, and Cenozoic units in southeast Missouri

The U.S. Geological Survey is conducting a regional water-resources investigation of the Gulf Costal Plain, which includes all of the Mississippi Alluvial Plain of southeastern Missouri, locally known as the southeast lowlands. The purpose of the regional study is to describe and evaluate the major aquifer systems in sediments of Tertiary and younger age in parts of 10 states (Grubb, 1984). In the southeast lowlands of Missouri, the sub-surface stratigraphy and structural configuration of geologic units need to be described in detail to define the major aquifer syustems in the area. The purpose of this report is to describe the subsurface geologic framework for Paleozoic, Mesozoic, and Cenozoic units in the southeast lowlands of Missouri and to correlate these units to those in adjecent States using geophysical and geologic methods (index map). Geophysical logs of wells were used to determine which units are aquifers or confining beds. The drilling of the U.S. Geological Survey test well 1-X in New Madrid County, Missouri, and the subsequent interpretation of geohydrologic data from the well have provided valuable information used in the preparation of this report.
