Hydrologic information on the variability of streamflow during low-flow periods is needed for the effective management of surface-water resources in Maryland and Delaware. Low-flow characteristics derived from streamflow under natural conditions are presented for 94 continuousrecord gaging stations in Maryland, Delaware, and surrounding States, and for 131 low-flow partial-record gaging stations in Maryland and Delaware. Methods are developed to estimate low-flow characteristics at ungaged stream sites for average 7-, 14-, and 30-consecutive-day lowflow discharges for recurrence intervals of 2, 10, and 20 years. The methods are applicable to unregulated streams in Maryland and Delaware for watersheds having drainage areas ranging from 2.0 to 875 square miles.
Maryland and Delaware are divided into four regions on the basis of physiography and the results of regression analyses. The regions are the Eastern Shore region in Maryland and Delaware, the eastern-Piedmont region in Maryland, the western region in Maryland, and the southern region in Maryland. Equations are developed from regression analyses to estimate lowflow characteristics at ungaged sites on ungaged streams for the Eastern Shore region, the easternPiedmont region, and the western region. A generalized least-squares multiple-regression technique is used to develop the estimation equations that relate average 7-, 14-, and 30- consecutive-day low-flow discharges for recurrence intervals of 2, 10, and 20 years to physical and climatological features of drainage basins in the study area. Adjustments are necessary to low-flow discharges estimated from the equation for the western region because of the effects of carbonate rocks on low flows. The adjustment method is based on analysis of the residuals of regional estimation equations and the percentage of the basin underlain by carbonate rocks. An equation is developed on the basis of a distance-weighted average of low-flow discharges at gaging stations to estimate low flow characteristics at ungaged sites on ungaged streams for the southern region. Estimates of the accuracy of low-flow characteristics determined from all regional equations are provided.
Two methods are presented for estimating low-flow characteristics at ungaged sites on gaged streams. One method combines low-flow characteristics determined from gaging station data with results from the regional regression equation at the gaging station and at the ungaged site to estimate the low-flow characteristics either upstream or downstream from the gaging station. The other method estimates low-flow characteristics at ungaged sites between gaging stations using a graphical solution. Estimates of accuracy of the low-flow characteristics determined by these methods also are provided.

An investigation by the U.S. Geological Survey, in cooperation with the U.S. Environmental Protection Agency, was done during 1994-95 to characterize the unconsolidated glacial deposits and the sedimentary bedrock, integrate the local geohydrologic conditions with the regional geohydrologic system, and develop a conceptual understanding of ground-water flow in the study area. A regional ground-water-flow model developed for the region near the study area indicates that perennial streams, including Judd Brook and the Tenmile River, form hydrologic divides that separate the larger region into hydraulically independent flow systems. In the local study area, synoptic water-level measurements made in June 1995 indicate that ground water near the water table flows west and southwestward from the low hill on the eastern side of the area toward the pond and wetlands along Judd Brook. Water-level data indicate that there is good hydraulic connection between the unconsolidated materials and underlying fractured bedrock. Unconsolidated materials in the study area consist principally of glacial stratified deposits that are fine sand, silt, and clay of glaci- olacustrine origin; locally these overlie thin glacial till. The glacial sediments range in thickness from a few feet to about 25 ft in the eastern part of the study area and are as much as 100 ft thick in the western and southern part of the study area beneath the Judd Brook and Tenmile River valleys. Fluvial redbeds of the New Haven Arkose underlie the glacial deposits in the region; in the study area, the redbeds consist of (1) channel sandstone units, which are coarse sandstone to fine conglomerate, generally in 6- to 15-ft- thick sequences; and (2) overbank mudstone units, which are siltstone and silty sandstone with some fine sandstone, generally in 6- to 50-ft-thick sequences. Thin-bedded zones of siltstone that are particularly fissile are present locally within the mudstone units. Rock units strike northward and dip eastward at about 20. The eastward-dipping strata are cut by a consistent set of west to west-northwest dipping, high-angle fractures. These fractures are oriented perpendicular to bedding and are present mostly in the channel sandstone units, but locally extend into the mudstone units as well. Borehole-geophysical logging indicates that ground water flows along bedding planes in fissile zones and between fissile zones in high-angle fractures, which are perpendicular to bedding. The combined fracture types form an aquifer system in which ground water follows a stair-step flowpath, flowing horizontally through fissile zones and vertically through high-angle fractures. Heat-pulse flow meter measurements and borehole fluid-conductivity and temperature logs indicate that only a small subset of the fissile zones and some high-angle fractures are hydraulically significant. A generalized local-scale ground-water flow model based on a nonspecific, but realistic, rock and fracture geometry was developed for the study area. Simulations show that under nonpumping conditions at a hypothetical well located in the middle of the model, ground-water flow was separated into upper and lower zones in which flow paths differed but were generally from northeast to southwest. Several short-duration aquifer tests conducted in the study area indicate that there is good hydraulic connection in the fractures between the pumping well (CS-221) and two bedrock wells located approximately 100 ft to the north and south along bedding strike. During the short duration of the aquifer tests, there was no hydraulic connection in bedrock wells located to the east, perpendicular to the strike. A range of transmissivity of 27 to 46 ft2/d was calculated from the aquifer-test data for the fractured-bedrock aquifer at CS-221 and TH-2.

Biogas (CH4and CO2) production was monitored with an automated pressure transducer system. Benzene, 1-methyl naphthalene, and methyltert-butyl ether (MTBE) were found to have no inhibitory influence on biogas production rates at concentrations up to 71·7 mg/L. Similarly, octane, cyclohexane, indan, and methyl ethyl ketone (MEK) were found to have only marginal negative effects on the rate of biogas production in aquifer slurries, at concentrations ranging from 51·7 to 72·1 mg/L. Thus, gasoline components had low apparent toxicities to microorganisms responsible for glucose methanogenesis in aquifier slurries. As the concentrations of the assayed hydrocarbons are about 100 times those typically reported after an aquifer has been contaminated with gasoline, it is unlikely that individual hydrocarbons will substantially impact anaerobic metabolic processes.

We develop a statistical technique to estimate the mesoscale average snow accumulation, using 8 years of snow course observations. For each of three major snow accumulation regions in the Upper Colorado River Basin – the Colorado Rocky Mountains, Colorado, the Uinta Mountains, Utah, and the Wind River Range, Wyoming – the snow course observations yield a correlation length scale of 38 km, 46 km, and 116 km respectively. This is the scale for which the snow course data at different sites are correlated with 70 per cent correlation. This correlation of snow accumulation over large distances allows for the estimation of the snow water equivalent on a mesoscale basis. With the snow course data binned into 1/4° latitude by 1/4° longitude pixels, an error analysis shows the following: for no snow course data in a given pixel, the uncertainty in the water equivalent estimate reaches 50 cm; that is, the climatological variability. However, as the number of snow courses in a pixel increases the uncertainty decreases, and approaches 5-10 cm when there are five snow courses in a pixel.

The South Florida Ecosystem Restoration Program is an intergovernmental effort, involving a number of agencies, to reestablish and maintain the ecosystem of south Florida. One element of the restoration effort is the development of a firm scientific basis for resource decision making.

The USGS began their own program, called the South Florida Ecosystem Program, in fiscal year 1995 for the purpose of gathering hydrologic, cartographic, and geologic data that relate to the mainland of south Florida, Florida Bay, and the Florida Keys and Reef ecosystems.
Management of the south Florida ecosystem involves the use of hydrologic models that simulate the flow of water through the region. As sheetflow is reestablished by flow management in the wetlands of the Everglades, it is expected that changes will also be reflected in the amount of freshwater exiting the mainland through the principal streams or as sheetflow into Florida Bay. Several agencies, including the USGS and the U.S. Army Corps of Engineers (COE), are planning to use hydrologic models to simulate and predict the flows into Florida Bay and the circulation patterns within the bay itself. These models can then be used to determine the effects that management of the inland water system will have on the amount of freshwater the bay receives from the mainland. This project will provide modelers with essential flow and specific conductance data along the mangrove zone where data have not been previously available.

Over the years, the construction of canals and levees has altered the natural hydrologic conditions of the Everglades. The canals and levees were constructed to convey water, prevent flooding, and store water in conservation areas for future use. The U.S. Army Corps of Engineers (COE) in Jacksonville, Fla., is planning to construct gated spillways and culverts to allow for the restoration of natural sheetflow conditions to Everglades National Park (ENP). These proposed changes may further affect the hydrologic conditions of ENP and other parts of the ecosystem, thus leading to the following questions:
Federal, State, and local agencies need to know the effect that changes in the operation of gates and control structures in canals will have on the water-budget components of the natural water systems in south Florida, including ground-water flow to Biscayne Bay.

and Recovery Act, is conducting environmental studies at its Support Center in Kodiak, Alaska, to determine if hazardous materials have been spilled or disposed of at the facility. The U.S. Geological Survey conducted a hydrologic evaluation of the Support Center to assess the extent of possible ground-water, surface-water, and soil contamination resulting from the handling of hazardous materials. This report describes the borehole and monitoring-well drilling program conducted on the Support Center by the U.S. Geological Survey. It contains maps and diagrams depicting well locations, logs, and construction details, as well as soil-sampling information for 121 boreholes, of which 102 were completed as water-quality monitoring wells.","language":"ENGLISH","publisher":"U.S. Geological Survey ;","doi":"10.3133/ofr96134","issn":"0094-9140","usgsCitation":"Carr, M., 1996, Description of wells drilled at the U.S. Coast Guard Support Center Kodiak, Alaska, 1988-89: U.S. Geological Survey Open-File Report 96-134, iii, 233 p. :ill, maps ;28 cm., https://doi.org/10.3133/ofr96134.","productDescription":"iii, 233 p. :ill, maps ;28 cm.","costCenters":[],"links":[{"id":153651,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1996/0134/report-thumb.jpg"},{"id":52124,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1996/0134/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aaee4b07f02db66c844","contributors":{"authors":[{"text":"Carr, M.R.","contributorId":42608,"corporation":false,"usgs":true,"family":"Carr","given":"M.R.","email":"","affiliations":[],"preferred":false,"id":188654,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70019077,"text":"70019077 - 1996 - The zeolite deposits of Greece","interactions":[],"lastModifiedDate":"2025-05-14T16:44:06.741156","indexId":"70019077","displayToPublicDate":"1996-09-01T00:00:00","publicationYear":"1996","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":2746,"text":"Mineralium Deposita","active":true,"publicationSubtype":{"id":10}},"title":"The zeolite deposits of Greece","docAbstract":"Zeolites are present in altered pyroclastic rocks at many localities in Greece, and large deposits of potential economic interest are present in three areas: (1) the Evros region of the province of Thrace in the north-eastern part of the Greek mainland; (2) the islands of Kimolos and Poliegos in the western Aegean; and (3) the island of Samos in the eastern Aegean Sea. The deposits in Thrace are of Eocene-Oligocene age and are rich in heulandite and/or clinoptilolite. Those of Kimolos and Poliegos are mainly Quaternary and are rich in mordenite. Those of Samos are Miocene, and are rich in clinoptilolite and/or analcime. The deposits in Thrace are believed to have formed in an open hydrological system by the action of meteoric water, and those of the western Aegean islands in a similar way but under conditions of high heat flow, whereas the deposits in Samos were formed in a saline-alkaline lake.","language":"English","publisher":"Springer Nature","doi":"10.1007/BF00196128","issn":"00264598","usgsCitation":"Stamatakis, M., Hall, A., and Hein, J., 1996, The zeolite deposits of Greece: Mineralium Deposita, v. 31, no. 6, p. 473-481, https://doi.org/10.1007/BF00196128.","productDescription":"9 p.","startPage":"473","endPage":"481","costCenters":[],"links":[{"id":226902,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"Greece","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"MultiPolygon\",\"coordinates\":[[[[23.69998,35.705],[24.24667,35.36802],[25.02502,35.425],[25.76921,35.35402],[25.74502,35.18],[26.29,35.29999],[26.165,35.005],[24.72498,34.91999],[24.73501,35.08499],[23.51498,35.27999],[23.69998,35.705]]],[[[26.6042,41.56211],[26.2946,40.93626],[26.05694,40.82412],[25.44768,40.85255],[24.92585,40.94706],[23.71481,40.68713],[24.408,40.12499],[23.89997,39.96201],[23.343,39.961],[22.81399,40.47601],[22.6263,40.25656],[22.84975,39.65931],[23.35003,39.19001],[22.9731,38.9709],[23.53002,38.51],[24.02502,38.21999],[24.04001,37.65501],[23.115,37.92001],[23.40997,37.40999],[22.77497,37.30501],[23.15423,36.42251],[22.49003,36.41],[21.67003,36.84499],[21.29501,37.64499],[21.12003,38.31032],[20.73003,38.76999],[20.21771,39.34023],[20.15002,39.625],[20.615,40.11001],[20.675,40.435],[20.99999,40.58],[21.02004,40.84273],[21.67416,40.93127],[22.05538,41.14987],[22.59731,41.13049],[22.76177,41.3048],[22.95238,41.33799],[23.69207,41.30908],[24.49264,41.5839],[25.1972,41.23449],[26.10614,41.3289],[26.11704,41.8269],[26.6042,41.56211]]]]},\"properties\":{\"name\":\"Greece\"}}]}","volume":"31","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505bb1ede4b08c986b3254bf","contributors":{"authors":[{"text":"Stamatakis, M.G.","contributorId":67222,"corporation":false,"usgs":true,"family":"Stamatakis","given":"M.G.","email":"","affiliations":[],"preferred":false,"id":381609,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hall, A.","contributorId":38720,"corporation":false,"usgs":true,"family":"Hall","given":"A.","email":"","affiliations":[],"preferred":false,"id":381607,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hein, J.R. 0000-0002-5321-899X","orcid":"https://orcid.org/0000-0002-5321-899X","contributorId":61429,"corporation":false,"usgs":true,"family":"Hein","given":"J.R.","affiliations":[],"preferred":false,"id":381608,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}} ,{"id":25483,"text":"wri964018 - 1996 - Estimated depth to the water table and estimated rate of recharge in outcrops of the Chicot and Evangeline aquifers near Houston, Texas","interactions":[],"lastModifiedDate":"2016-08-22T10:24:53","indexId":"wri964018","displayToPublicDate":"1996-09-01T00:00:00","publicationYear":"1996","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":342,"text":"Water-Resources Investigations Report","code":"WRI","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"96-4018","title":"Estimated depth to the water table and estimated rate of recharge in outcrops of the Chicot and Evangeline aquifers near Houston, Texas","docAbstract":"In 1989, the U.S. Geological Survey, in cooperation with the Harris-Galveston Coastal Subsidence District, began a field study to determine the depth to the water table and to estimate the rate of recharge in outcrops of the Chicot and Evangeline aquifers near Houston, Texas. The study area comprises about 2,000 square miles of outcrops of the Chicot and Evangeline aquifers in northwest Harris County, Montgomery County, and southern Walker County. Because of the scarcity of measurable water-table wells, depth to the water table below land surface was estimated using a surface geophysical technique, seismic refraction. The water table in the study area generally ranges from about 10 to 30 foot below land surface and typically is deeper in areas of relatively high land-surface altitude than in areas of relatively low land- surface altitude. The water table has demonstrated no long-term trends since ground-water development began, with the probable exception of the water table in the Katy area: There the water table is more than 75 feet deep, probably due to ground-water pumpage from deeper zones. An estimated rate of recharge in the aquifer outcrops was computed using the interface method in which environmental tritium is a ground-water tracer. The estimated average total recharge rate in the study area is 6 inches per year. This rate is an upper bound on the average recharge rate during the 37 years 1953-90 because it is based on the deepest penetration (about 80 feet) of postnuclear-testing tritium concentrations. The rate, which represents one of several components of a complex regional hydrologic budget, is considered reasonable but is not definitive because of uncertainty regarding the assumptions and parameters used in its computation.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Austin, TX","doi":"10.3133/wri964018","collaboration":"Prepared in cooperation with the Harris-Galveston Coastal Subsidence District","usgsCitation":"Noble, J.E., Bush, P.W., Kasmarek, M., and Barbie, D., 1996, Estimated depth to the water table and estimated rate of recharge in outcrops of the Chicot and Evangeline aquifers near Houston, Texas: U.S. Geological Survey Water-Resources Investigations Report 96-4018, Document: iii, 19 p.; Plate: 21 x 24 inches, https://doi.org/10.3133/wri964018.","productDescription":"Document: iii, 19 p.; Plate: 21 x 24 inches","costCenters":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"links":[{"id":122845,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri_96_4018.jpg"},{"id":8708,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/wri/wri96-4018/","linkFileType":{"id":5,"text":"html"}},{"id":8709,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/wri96-4018/pdf/wri96-4018_plate.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Texas","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a81e4b07f02db64a394","contributors":{"authors":[{"text":"Noble, J.

The geologic units of concern underlying this area are the carbonates of the Niagaran Series, the Detroit River and Traverse Formations; the Antrim Shale; and sands, silts, and clays of Quaternary age. The hydrologic units of concern are surface water, the Calumet aquifer, the confining unit, and the Silurian-Devonian aquifer.
\nWater levels collected in June 1992 indicate that the water-table configuration generally is a subdued reflection of topography. Recharge from landfill leachate and ponded water, discharge to sewers, and pumping also affect the water-table configuration. A depression in the potentiometric surface of the Silurian-Devonian aquifer results from pumping. Light-nonaqueous-phase liquids were detected near petroleum handling, industrial and waste-disposal facilities.
\nHorizontal ground-water velocity at the water table in the confining unit ranged from 4.4x10-4 to 1.0x10-3 feet per day. Horizontal ground-water velocity in the Calumet and Silurian-Devonian aquifers ranged from 1.0x10-2 to 3.4x10-1 and from 1.4x10-2 to 2.9x10-2 feet per day, respectively.
\nVertical hydraulic gradients indicate generally downward flow from the Calumet aquifer into the confining unit, then into the Silurian-Devonian aquifer. Calculated vertical groundwater velocity through the weathered and unweathered parts of the confining unit are 3.8x10-2 and 1.5x10-3 feet per day, respectively.

Land resource provinces have been designated based on generalized soil classifications. Land resource provinces in the study area include: the Coastal Flatwoods, the Southern Coastal Plain, the Central Florida Ridge, the Sand Hills, and the Southern Piedmont. The study area includes all or parts of seven hydrologic subregions: the Ogeechee-Savannah, the Altamaha- St.Marys, the Suwannee, the Ochlockonee, the St. Johns, the Peace-Tampa Bay, and the Southern Florida. The primary source of water for public supply in the study area is ground water from the Upper Floridan aquifer. In 1990, more than 90 percent of the 2,888 million gallons per day of ground water used came from this aquifer. The population of the study area was 9.3 million in 1990. The cities of Jacksonville, Orlando, St. Petersburg, Tallahassee, and Tampa, Florida, and parts of Atlanta and Savannah, Georgia, are located in the study area. Forest and agricultural areas are the most common land uses in the study area, accounting for 48 percent and 25 percent of the study area, respectively. Climatic conditions range from temperate in Atlanta, Georgia, where mean annual temperature is about 61.3 degrees Fahrenheit, to subtropical in Tampa, Florida, where mean annual temperature is about 72.4 degrees Fahrenheit. Long-term average precipitation (1961-90) ranges from 43.9 inches per year in Tampa, Florida, and 44.6 in Macon, Georgia, to 65.7 inches per year in Tallahassee, Florida. Floods in the study area result from frontal systems, hurricanes, tropical storms, or severe thunderstorms. Droughts are not common in the study area,especially in the Florida part of the study area due to extensive maritime exposure. The primary physical and cultural characteristics in the study area include physiography, soils and land resource provinces, geologic setting, ground-water systems, surface- water systems, climate, floods, droughts, population, land use, and water use. Factors affecting water quality in the study area are land use (primarily urban and agricultural land uses), water use in coastal areas, hydrogeology, ground-water/surface-water interaction, geology, and climate. Surface-water quality problems in urban areas have occurred in the Ogeechee, Canoochee, Ocmulgee, St. Marys, Alapaha, Withlacoochee (north), Santa Fe, Ochlockonee, St. Johns, and Oklawaha Rivers and include nitrogen and phosphorus loading, low dissolved oxygen, elevated bacteria, sediment, and turbidity, and increased concentrations of metals. In agricultural areas, surface-water quality problems include elevated nitrogen and phosphorus concentrations, erosion, and sedimentation and have occurred in the Ocmulgee, St. Marys, Santa Fe, Ochlockonee, St. Johns, Oklawaha, Withlacoochee (South), Hillsborough, and Alafia Rivers. Ground water-quality problems such as saltwater intrusion have occurred mostly in coastal areas and were caused by excessive withdrawals.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri954268","usgsCitation":"Berndt, M.P., Oaksford, E., Darst, M.R., and Marella, R., 1996, Environmental setting and factors that affect water quality in the Georgia-Florida Coastal Plain study unit: U.S. Geological Survey Water-Resources Investigations Report 95-4268, vi, 46 p., https://doi.org/10.3133/wri954268.","productDescription":"vi, 46 p.","costCenters":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":413787,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_48341.htm"},{"id":54202,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1995/4268/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":123657,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1995/4268/report-thumb.jpg"}],"country":"United States","state":"Florida, Georgia","otherGeospatial":"Georgia-Florida Coastal Plain","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"properties\":{},\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-84.7210693359375,30.704058230919504],[-84.90234375,30.543338954230222],[-85.0177001953125,30.24957724046765],[-84.803466796875,30.164126343161097],[-84.627685546875,29.935895213372444],[-84.57275390625,29.859701442126756],[-84.44091796875,29.859701442126756],[-84.29809570312499,29.859701442126756],[-84.2926025390625,30.012030680358613],[-84.17724609375,30.035811042667792],[-83.990478515625,30.050076521698735],[-83.7322998046875,29.893043385434165],[-83.6224365234375,29.76914573606667],[-83.51806640624999,29.602118211647333],[-83.397216796875,29.415675471217877],[-83.2489013671875,29.377388403478992],[-83.1610107421875,29.233683670282787],[-83.0841064453125,29.1281717828162],[-82.8753662109375,29.10897615145302],[-82.77099609375,28.945668833650508],[-82.75451660156249,28.815799886487298],[-82.694091796875,28.671310915880834],[-82.694091796875,28.492833128965096],[-82.8094482421875,28.265682390146477],[-82.891845703125,28.164032516628076],[-82.869873046875,27.955591004642553],[-82.8973388671875,27.790491224830877],[-82.7874755859375,27.68352808378776],[-82.75451660156249,27.552111841284695],[-80.299072265625,27.571590861376308],[-80.2935791015625,27.649472352561876],[-80.37597656249999,27.848790459862073],[-80.52429199218749,28.105903469076186],[-80.540771484375,28.20760859532738],[-80.540771484375,28.318888915773826],[-80.5133056640625,28.386567819657213],[-80.46936035156249,28.44454394857482],[-80.518798828125,28.647210004919998],[-80.6341552734375,28.815799886487298],[-80.771484375,29.065772888415406],[-81.0406494140625,29.439597566602902],[-81.1614990234375,29.807284450222504],[-81.27685546875,30.107117887092357],[-81.3592529296875,30.5764500266181],[-81.34277343749999,30.873940237887624],[-81.32080078125,31.052933985705163],[-81.23291015625,31.22689446881399],[-81.19445800781249,31.358327833411312],[-81.14501953125,31.48020882071693],[-81.03515625,31.648705289976853],[-80.958251953125,31.835565983656227],[-80.85937499999999,31.94750122367064],[-80.782470703125,32.00341778396365],[-80.8978271484375,32.0732655510424],[-81.046142578125,32.115148622612445],[-81.1175537109375,32.16166284018013],[-81.112060546875,32.2546200600072],[-81.0955810546875,32.30570601389429],[-81.177978515625,32.43097672054704],[-81.1669921875,32.47732919639942],[-81.24938964843749,32.537551746769],[-81.34277343749999,32.59773394005744],[-81.4031982421875,32.648625783736726],[-81.39770507812499,32.76880048488168],[-81.4031982421875,32.86574639547474],[-81.441650390625,32.95797741405952],[-81.4801025390625,33.04550781490999],[-81.5899658203125,33.1329513125159],[-81.73278808593749,33.15594830078649],[-81.88110351562499,33.330528249028085],[-82.06787109374999,33.41310221370827],[-82.28759765625,33.348884792201694],[-82.5732421875,33.22949814144951],[-83.056640625,33.25706340236547],[-83.33129882812499,33.0178760185549],[-83.507080078125,32.80574473290688],[-83.82568359375,32.722598604044066],[-83.66638183593749,32.263910555201306],[-83.7652587890625,32.05464469054932],[-83.8421630859375,31.76086695137955],[-84.19921875,31.353636941500987],[-84.6826171875,30.869225348040825],[-84.7210693359375,30.704058230919504]]]}}]}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a13e4b07f02db602280","contributors":{"authors":[{"text":"Berndt, M.

Data presented are from January 1993 through December 1995, although the report focuses on hydrologic events from October through December 1995 (fourth quarter of 1995). Cumulative rainfall for October through December 1995 was about 41 inches, which is 32 percent more than the mean cumulative rainfall of about 31 inches for October through December. The period October through December is within the annual wet season. Mean cumulative rainfall is calculated for the fixed base period 1951-90. Ground-water withdrawal during October through December 1995 averaged 931,000 gallons per day. Withdrawal for the same 3 months in 1994 averaged 902,900 gallons per day. Patterns of withdrawal during the fourth quarter of 1995 did not change significantly since 1993 at all five ground-water production areas. At the end of December 1995, the chloride concentration of the composite water supply was 60 milligrams per liter, well below the 250 milligrams per liter secondary drinking-water standard established by the U.S. Environmental Protection Agency. Chloride concentrations of the composite water supply from October through December 1995 ranged between 28 and 67 milligrams per liter. Chloride concentration of ground water in monitoring wells at Cantonment and Air Operations continued to decrease during the fourth quarter of 1995, with water from the deepest monitoring wells decreasing in chloride concentration by as much as 2,000 milligrams per liter. This trend follows increases in chloride concentration during the first half of 1995. A fuel leak at Air Operations caused the shutdown of ten wells in May 1991. Four of the wells resumed pumping for water-supply purposes in April 1992. The remaining six wells are being used to hydraulically divert fuel migration away from water-supply wells by recirculating about 150,000 gallons of water each day.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nEarth Science Information Center, Open-File Reports Section [distributor],","doi":"10.3133/ofr96183","issn":"0094-9140","usgsCitation":"Torikai, J., 1996, Status of ground-water resources at U.S. Navy Support Facility, Diego Garcia; summary of hydrologic and climatic data, January 1993 through December 1995: U.S. Geological Survey Open-File Report 96-183, v, 42 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr96183.","productDescription":"v, 42 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":157834,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1996/0183/report-thumb.jpg"},{"id":53730,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1996/0183/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4afee4b07f02db6973b5","contributors":{"authors":[{"text":"Torikai, J.D.","contributorId":93926,"corporation":false,"usgs":true,"family":"Torikai","given":"J.D.","affiliations":[],"preferred":false,"id":192400,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":28272,"text":"wri954178 - 1996 - Laboratory and quality assurance protocols for the analysis of herbicides in ground water from the Management Systems Evaluation Area, Princeton, Minnesota","interactions":[],"lastModifiedDate":"2019-12-08T13:12:45","indexId":"wri954178","displayToPublicDate":"1996-09-01T00:00:00","publicationYear":"1996","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":342,"text":"Water-Resources Investigations Report","code":"WRI","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"95-4178","title":"Laboratory and quality assurance protocols for the analysis of herbicides in ground water from the Management Systems Evaluation Area, Princeton, Minnesota","docAbstract":"Laboratory and quality assurance procedures for the analysis of ground-water samples for herbicides at the Management Systems Evaluation Area near Princeton, Minnesota are described.
