Results of a study, using data from the Minnesota Pollution Control Agency, Metropolitan Waste Control Commission, and the U.S. Geological Survey, indicate that selected water-quality characteristics differ significantly among subbasins. Results of the study also indicate that the quality of water leaving the basin at Hastings is affected primarily by inflow from the Minnesota River and by effluent from the Metropolitan sewage-treatment plant.</p>\n<p>Subbasins in the western part of the study area are underlain by prairie soils and cultivation of row crops is a common land use. Streams draining these subbasins have a median dissolved-solids concentration of 389 mg/L (milligrams per Liter) and a median concentration of nitrite plus nitrate nitrogen of 0.59 mg/L. Subbasins in the northern and eastern parts of the study area are underlain by more acidic podzol soils. Land use in these subbasins is less devoted to cultivated crops; forested areas, pastures, and wetlands are common. Streams draining these subbasins have a median dissolved- solids concentration of 184 mg/L and a median concentration of nitrite plus nitrate nitrogen of 0.17 mg/L.</p>\n<p>The quality of water changes dramatically in the most downstream subbasin, which includes the Twin Cities Metropolitan Area. On the basis of hourly data from automatic monitors, specific conductance increases from 345 /<span>&mu;</span>S/cm (microsiemens per centimeter) at 25&deg; Celsius above the confluence with the Minnesota River to 467 /<span>&mu;</span>S/cm below it. Specific conductance increases to a median of 513 /<span>&mu;</span>S/cm where effluent from the Metropolitan sewage-treatment plant enters the Mississippi River.</p>\n<p>Dissolved-oxygen concentrations in the Mississippi River begin to decline below the confluence with the Minnesota River. Concentrations of dissolved oxygen reach a minimum median value in summer of 6.3 mg/L at a point about 9 miles downstream from the Metropolitan sewage-treatment plant. In winter, minimum median concentration is downstream at Lock and Dam 2, which is approximately 20 miles below the plant.</p>\n<p>Results of this study show that the quality of water in the Mississippi River as it leaves the accounting unit at Hastings is not representative of water quality in most of the accounting unit. Three water-quality regions have been identified, and sampling sites are needed in each region to assess the quality of streams throughout the study area

The basin has undergone land subsidence of as much as 3.8 meters since the 1930's owing to compaction of the aquifer system in response to ground-water-level declines that have exceeded 100 meters. The fissure, which extends generally north-south for 15 kilometers, exhibits horizontal tensile failure and as much as 0.6 meter of normal dip-slip movement at the land surface. The west side of the fissure is downthrown. The fissure was observed as early as 1927 and is the longest earth fissure in Arizona.</p>","language":"English","publisher":"U.S. Geological

Model results indicate that about 96 percent of the total inflow to the modeled area is from precipitation. Discounting evapotranspiration, 63 percent of the total outflow is ground-water discharge to the East Branch Chippewa and North Fork Crow Rivers, and 34 percent is ground-water pumpage.</p>\n<p>The model was used to simulate the steady-state effects of below-normal precipitation (drought) and hypothetical increases in ground-water development. Model results indicate that reduced recharge and increased pumping during a hypothetical 3-year extended drought would lower regional water levels from 2 to 5 feet in each aquifer and as much as 20 feet in the lowermost aquifer zone; ground-water discharge to the East Branch Chippewa and North Fork Crow Rivers would be reduced by 38 percent. The addition of 10 to 20 hypothetical wells in confined aquifers, pumping 123 to 246 million gallons per year, would result in regional water-level declines of 0.1 to 0.5 feet. Simulated water-level declines in wells completed in the lower part of the system would be as much as 5.0 feet as a result of pumping 246 million gallons per year from 20 hypothetical wells. Water-level declines in overlying and underlying aquifers would range from 0.4 to 2.8 feet. Ground-water discharge to the East Branch Chippewa and North Fork Crow Rivers would be unaffected by the pumpage.</p>","language":"English","publisher":"U.S. Geological

In the Great Basin, this\ntranslates into searching for ore bodies buried by alluvial cover.

The Tertiary and Quaternary clastic deposits have an areal extent of 114,000 square miles onshore and in the Gulf of Mexico. Two distinct aquifer systems are recognized within the sediments, which range in thickness from a few feet to more than 12,000 feet The older system--the Texas coastal uplands aquifer system-consists of four aquifers and two confining units in the Claiborne and Wilcox Groups. It is underlain by the practically impermeable Midway confining unit or by the top of the geopressured zone. It is overlain by the nearly impermeable Vicksburg-Jackson confining unit, which separates it from the younger coastal lowlands aquifer system. The coastal lowlands aquifer system consists of five permeable zones and two confining units that range in age from Oligocene to Holocene. The hydrogeologic units of both systems are exposed in bands that parallel the coastline. The units dip and thicken toward the Gulf. Quality of water in the aquifer systems is highly variable, with dissolved solids ranging from less than 500 to 150,000 milligrams per liter.</p><p>Substantial withdrawal from the aquifer systems began in the early 1900's and increased nearly continuously into the 1970's. The increase in withdrawal was relatively rapid from about 1940 to 1970. Adverse hydrologic effects, such as saltwater encroachment in coastal areas, land-surface subsidence in the Houston-Galveston area, and long-term dewatering in the Whiter Garden area, were among some of the factors that caused pumping increases to slow or to cease in the 1970's and 1980's.</p><p>Ground-water withdrawals in the study area in 1980 were about 1.7 billion gallons per day. Nearly all of the withdrawal was from four units: Permeable zones A, B, and C of Miocene age and younger, and the lower Claiborae-upper Wilcox aquifer. Ground-water levels have declined hundreds of feet in the intensively pumped areas of Houston-Galveston, Kingsville, Winter Garden, and Lufkin-Nacogdoches. Water-level declines have caused inelastic compaction of clays which, in turn, has resulted in land-surface subsidence of more than one foot in an area of about 2,000 square miles. Maximum subsidence of nearly 10 feet occurs in the Pasadena area east of Houston.</p><p>A three-dimensional, variable-density digital model was developed to simulate predevelopment and transient flow in the aquifer systems. The modeled area is larger than the study area, and includes adjacent parts of Louisiana and Mexico. The transient model calibration period was from 1910 (predevelopment) to 1982. Model-generated head distributions, water-level hydrographs, and land-surface subsidence were matched to measured data in selected, intensively pumped areas.</p><p>For the study area, mean horizontal hydraulic conductivity in the calibrated model ranges from 10 feet per day for the middle Wilcox aquifer to 25 feet per day for permeable zone A. Mean transmissivity ranges from about 4,600 feet squared per day for the middle Claiborne aquifer to about 10,400 feet squared per day for permeable zone D. Mean vertical hydraulic conductivity ranges from 1.1x10<sup>-5</sup> feet per day for the Vicksburg-Jackson confining unit, to 3.8x10<sup>-3</sup> feet per day for permeable zone A. Mean values of calibrated storage coefficient range from 52x10<sup>-4</sup> for the middle Claiborne aquifer to 1.7x10<sup>-3</sup> for the middle Wilcox aquifer and permeable zone C. Calibrated inelastic specific storage values for clay beds in permeable zones A, B, and C in the Houston-Galveston area are 8.5x10<sup>-5</sup>, 8.0x10<sup>-5</sup>, and 8.0x10<sup>-6</sup> feet<sup>-1</sup>, respectively. These values are 85, 80, and 8 times greater than the estimated elastic specific storage value for the clays in permeable zones A, B, and C, respectively.</p><p>Recharge rates were mapped for predevelopment conditions as determined from a steady-state model calibration. A maximum rate of 3 inches per year was simulated in small areas, and the average rate for the study area was 034 inch per year. Total simulated recharge was 85 million cubic feet per day in the outcrop area. Recharge was equal to discharge in outcrop areas (79 million cubic feet per day) plus net lateral flow out of the study area (6 million cubic feet per day).</p><p>Rates of inflow and outflow to the ground-water system have nearly tripled from predevelopment to 1982 (85 to 276 million cubic feet per day) based on model simulation. Withdrawal of 231 million cubic feet per day was supplied principally by an increase in outcrop recharge and, to a lesser extent, from a decrease in natural discharge and release of water from storage in aquifers and compacting clay beds. The average simulated 1982 recharge rate for the study area was 0.52 inch per year, with a maximum simulated rate of 6 inches per year in Jackson and Wharton Counties.</p><p>Because withdrawal has caused problems such as saltwater intrusion, land-surface subsidence, and aquifer dewatering, the Texas Department of Water Resources has projected that ground-water use will decline substantially in most of the study area by the year 2030. Some areas remain favorable for development of additional ground-water supplies. Pumping from older units that are farther inland and in areas where potential recharge is greater will minimize adverse hydrologic effects.</p>","language":"English","publisher":"U.S. Geological

The eastern part of the State, particularly Belmont, Harrison, and Jefferson Counties, sustained the most damage. In the Pipe and Wegee Creek basins near Shadyside, Belmont County, at least 24 people died and property damage exceeded $10 million.\r\n\r\nAn indirect measurement of discharge on Pipe Creek made near the mouth, indicates a peak discharge of 15,000 ft? /s (cubic feet per second) for the drainage area of 11.3 mi? (square miles) and a unit discharge of 1,330 (ft? /s)/mi? (cubic feet per second per square mile). The recurrence interval for this peak discharge is greater than 100 years. An indirect measurement of discharge of Wegee Creek, made 3 miles upstream from the mouth, indicates a peak discharge of 2,200 (ft? /s) /mi? . The recurrence interval for this peak discharge also is greater than 100 years. Longitudal water-surface profiles showed depths ranging from 7 ft. to 22 ft.\r\n\r\nThe severity of flooding was highly variable. For example, the recurrence interval of the peak discharge at one U.S. Geological Survey streamflow-gaging station was only 2 years, whereas the recurrence interval for the peak discharge was greater than 100 years at another gaging station about 22 miles away.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey ;\r\nBooks and Open-File Reports Section [distributor],","doi":"10.3133/wri914147","usgsCitation":"Shindel, H., 1991, Flood of June 14-15, 1990, in Belmont, Jefferson, and Harrison counties, Ohio, with emphasis on Pipe and Wegee Creek basins near Shadyside: U.S. Geological Survey Water-Resources Investigations Report 91-4147, vi, 33 p. :ill., maps ;28 cm., https://doi.org/10.3133/wri914147.","productDescription":"vi, 33 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":126784,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1991/4147/report-thumb.jpg"},{"id":58524,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1991/4147/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ab2e4b07f02db66eb95","contributors":{"authors":[{"text":"Shindel, H.L.","contributorId":17652,"corporation":false,"usgs":true,"family":"Shindel","given":"H.L.","affiliations":[],"preferred":false,"id":201982,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The project was designed as a technique to: (1) Assign priorities for development of ground-water management and monitoring programs; (2) build support for, and public awareness of, vulnerability of ground water to contamination; (3) assist in the development of regulatory programs; and (4) provide access to technical data through the use of a GIS (geographic information system) (C. Grantham, Idaho Department of Health and Welfare, written commun., 1989). Digital representation of first-encountered water below land surface is an important element in evaluating vulnerability of ground water to contamination. Depth-to-water values were developed using existing data and computer software to construct a GIS data set to be combined with a soils data set developed by the SCS (Soul Conservation Service) and the IDHW/WQB (Idaho Department of Health and Welfare/Water Quality Bureau), and a recharge data set developed by the IDWR/RSF (idaho Department of Water Resources/Remote Sensing Facility).

In this area, the Fruitland Formation contains an estimated 252 million short tons of coal in beds that range from 1.2 to 14 feet thick. About 100 million short tons of coal occur under less than 500 feet of overburden in the Ute Canyon, Upper Main, and Main coal beds. These three coal beds reach a cumulative coal thickness of about 18 feet in a stratigraphic interval that averages about 120 feet thick in the prospecting permit area, which is located in the extreme southwestern part of the study area. The southwestern part of the study area is probably best suited for surface mining, although steep dips may reduce minability locally. A major haul road that was recently constructed across the eastern half of the study area greatly improves the potential for surface mining. </p><p>Core sample analyses indicate that the apparent rank of the Ute Canyon, Upper Main, and Main coal beds is high-volatile C bituminous.

The area is characterized by north- to northwest-trending mountains separated by alluvial basins that form a regional topography of alternating mountains and valleys. On the basis of ground-water divides or zones of minimal basin interconnection, the area was divided into 72 basins, each representing an individual aquifer system. These systems are joined in a dendritic pattern and collectively constitute the major water resource in the region. \r\n\r\nGeochemical models were developed to identify reactions and mass transfer responsible for the chemical evolution of the ground water. On the basis of mineralogy and chemistry of the two major rock associations of the area, a felsic model and a mafic model were developed to illustrate geologic, climatic, and physiographic effects on ground-water chemistry. Two distinct hydrochemical processes were identified: (1) reactions of meteoric water with minerals and gases in recharge areas and (2) reactions of ground water as it moves down the hydraulic gradient. Reactions occurring in recharge and downgradient areas can be described by a 13-component system. Major reactions are the dissolution and precipitation of calcite and dolomite, the weathering of feldspars and ferromagnesian minerals, the formation of montmorillonite, iron oxyhydroxides, and probably silica, and, in some basins, ion exchange. \r\n\r\nThe geochemical modeling demonstrated that relatively few phases are required to derive the ground-water chemistry; 14 phases-12 mineral and 2 gas-consistently account for the chemical evolution in each basin. The final phases were selected through analysis of X-ray diffraction and fluorescence data, aqueous speciation and saturation data, and mass-balance and isotopic constraints and through chemical models developed from mineral combinations among the 27 phases that were considered realistic in these geologically and mineralogically complex basins. X-ray diffraction of basin-fill sediments confirm the presence of the postulated minerals and their weathering sequences. \r\n\r\nHigh partial pressures of soil CO2 and large concentrations of dissolved CO2 in recharge areas, and the rapid depletion of CO2 downgradient, accompanied by high weathering rates of the silicates which also decrease downgradient, indicate that carbonic acid is the impetus in the weathering process. Reactions in the soil zone and the unsaturated zone are influential and, in some instances, are as important as the mineralogy of the source rock in determining ground-water compositions. \r\n\r\nThe basins can be divided geochemically into two general categories-closed systems, which evolve under closed hydrologic conditions, and open systems, which are open to CO2 and other constituents along the flow path. The ground-water chemistry of the unconfined aquifers in the eastern part of the study area and of the aquifers underlying the flood plain along the Colorado River generally evolves under open conditions. The ground-water chemistry of most basins in the central and western parts and of the confined aquifers in the eastern part evolves under closed conditions. The factors that determine whether a basin is an open or closed system are the amount of and the spatial and seasonal distribution of annual precipitation and the presence or absence of fine-grained confining units. \r\n\r\nThe basins along the Colorado River are unique among basins in the region. Virtually all ground water underlying the flood plain originated as seepage or overbank flow from the Colorado River. Initial deuterium content of about -120 per mil is indicative of precipitation from the central part of Colorado.

Jackson Utility Division in Jackson, Madison County, Tennessee, pumps about 9 million gallons of ground water daily from two municipal wellfields that tap an unconfined sand aquifer. Under natural hydraulic gradients, ground waterflows southward toward the South Wellfield at approximately 2 to 3 feet per day; natural flow toward the North Wellfield from the east at 1 to 2 feet per day. Water quality generally is suitable for most uses. Concentrations of dissolved solids are low, and excessive iron is the only significant naturally occurring water-quality problem. However, trace concentrations of volatile organic compounds have been detected in water pumps from the South Wellfield; the highest concentration of a single compound has been 23 micrograms per liter of tetrachloroethylene. Potential sources of ground-water contamination in the Jackson area include a hazardous-waste site, municipal and industrial landfill, and underground-storage tanks. Some of the four method for delineating wellhead protection areas did not adequately describe zones contributing flow to the wellfields. Calculations based on a uniform flow equation provided a preliminary delineation of zones of contribution for the wellfields and ground-water time-of-travel contours. Limitations of the applied methods motivated the design of a more rigorous hydrogeologic investigation.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri894201","usgsCitation":"Broshears, R.E., Connell, J.F., and Short, N.C., 1991, A pilot study for delineation of areas contributing water to wellfields at Jackson, Tennessee: U.S. Geological Survey Water-Resources Investigations Report 89-4201, v, 32 p., https://doi.org/10.3133/wri894201.","productDescription":"v, 32 p.","costCenters":[],"links":[{"id":2033,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri89-4201","linkFileType":{"id":5,"text":"html"}},{"id":123101,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri_89_4201.jpg"},{"id":411388,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_47277.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Tennessee","city":"Jackson","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -88.9087415944655,\n              35.70309960291026\n            ],\n            [\n              -88.9087415944655,\n              35.54833536637487\n            ],\n            [\n              -88.75868085679966,\n              35.54833536637487\n            ],\n            [\n              -88.75868085679966,\n              35.70309960291026\n            ],\n            [\n              -88.9087415944655,\n              35.70309960291026\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1fe4b07f02db6ab881","contributors":{"authors":[{"text":"Broshears, R.
