As part of a cooperative study with the Indiana Department of Environmental Management, the U.S. Geological Survey compiled a computerized data base of nitrate concentrations in Indiana ground water. The data included nitrate determinations from more than 29 studies by five Federal and State agencies during June 1973 through August 1991. The National Water Information System software of the U.S. Geological Survey was used to store the data at the U.S. Geological Survey office in Indianapolis, Indiana. Electronic data sets were converted to a standard format of well data, sample data, and analytical data. Data were screened by several error-checking procedures before they were retained in the data base; they were examined for potential duplicates of well location and name.
\nThe data base of nitrate concentrations in Indiana ground water contains records of 5,525 samples collected from 4,448 wells in 88 of 92 counties during 1973-91. Those wells included 3,832 drinking-water wells; 536 monitoring wells, 38 livestock-supply wells; and 42 irrigation wells. Nitrate concentrations greater than minimum reporting limits of 0.0 to 0.5 milligrams per liter (mg/L) were determined in 2,453 samples (44 percent of the total). Nitrate in ground water at concentrations greater than 3 mg/L have been considered to be the result of human activities. Nitrate concentrations ranged from 0.005 to 380 mg/L with a median nitrate concentration of 0.3 mg/L. Nitrate concentrations were greater than or equal to 3 mg/L in 704 samples (13 percent of the total). Nitrate concentrations were greater than or equal to the U.S. Environmental Protection Agency Maximum Contaminant Level of 10 mg/L in 188 samples (3.4 percent of the total). Of the 3,832 drinking- water wells in the data base, 147 had at least one sample in which a nitrate concentration was greater than the Maximum Contaminant Level. The percentage of samples with nitrate concentrations greater than or equal to 3 mg/L and greater than or equal to 10 mg/L generally increased during the period 1973 through 1991.
\nThe nitrate data base was compiled from numerous data sets that were readily accessible in electronic format. The uses of these data may be limited because they were neither comprehensive nor of a single statistical design. Nonetheless, the nitrate data can be used in several ways: (1) to identify geographic areas with and without nitrate data; (2) to evaluate assumptions, models, and maps of ground-water-contamination potential; and (3) to investigate the relation between environmental factors, land-use types, and the occurrence of nitrate.

conditions at selected landfills in Mecklenburg County, North Carolina, 1986-92","docAbstract":"Water-quality conditions at five municipal landfills in Mecklenburg County, North Carolina, were studied during 1986-92. Analytical results of water samples from monitoring wells and streams at and near the landfills were used to evaluate effects of leachate on surface and ground water. Ground-water levels at monitoring wells were used to determine directions of ground-water flow at the landfills. Data from previous studies were used for analysis of temporal trends in selected water-quality properties and chemical constituents.\r\n\r\nEffects of leachate, such as large biochemical- and chemical-oxygen demands, generally were evident in small streams originating within the landfills, whereas effects of leachate generally were not evident in most of the larger streams. In larger streams, surface-water quality upstream and downstream from most of the landfills was similar. However, the chemical quality of water in Irwin Creek appears to have been affected by the Statesville Road landfill. Concentrations of several constituents indicative of leachate were larger in samples collected from Irwin Creek downstream from the Statesville Road landfill than in samples collected from Irwin Creek upstream from the landfill.\r\n\r\nThe effect of leachate on ground-water quality generally was largest in water from wells adjacent to waste-disposal cells. Concentrations of most constituents considered indicative of leachate generally were smaller with increasing distance from waste-disposal cells. Water samples from offsite wells generally indicated no effect or very small effects of leachate.\r\n\r\nAction levels designated by the Mecklenburg County Engineering Department and maximum contaminant levels established by the U.S. Environmental Protection Agency were exceeded in some samples from the landfills. Ground-water samples exceeded action levels and maximum contaminant levels more commonly than surface-water samples. Iron and manganese were the constituents that most commonly exceeded action levels in water samples from the landfills.\r\n\r\nSynthetic organic compounds were detected more commonly and in larger concentrations in ground-water samples than in surface-water samples. Concentrations of synthetic organic compounds detected in water samples from monitoring sites at the landfills generally were much less than maximum contaminant levels. However, concentrations of some chlorinated organic compounds exceeded maximum contaminant levels in samples from several monitoring wells at the Harrisburg Road and York Road landfills.\r\n\r\nTrend analysis indicated statistically significant temporal changes in concentrations of selected water-quality constituents and properties at some of the monitoring sites. Trends detected for the Holbrooks Road and Statesville Road landfills generally indicated an improvement in water quality and a decrease in effects of leachate at most monitoring sites at these landfills from 1979 to 1992. Water-quality trends detected for monitoring sites at the Harrisburg Road and York Road landfills, the largest landfills in the study, differed in magnitude and direction. Upward trends generally were detected for sites near recently closed waste-disposal cells, whereas downward trends generally were detected for sites near older waste-disposal cells. Temporal trends in water quality generally reflected changes in degradation processes associated with the aging of landfill wastes.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nEarth Science Information Center, Open-File Reports Section [distributor],","doi":"10.3133/wri954067","usgsCitation":"Ferrell, G., and Smith, D., 1995, Water-quality conditions at selected landfills in Mecklenburg County, North Carolina, 1986-92: U.S. Geological Survey Water-Resources Investigations Report 95-4067, vi, 112 p. :ill., maps ;28 cm., https://doi.org/10.3133/wri954067.","productDescription":"vi, 112 p. :ill., maps ;28 cm.","costCenters":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":158688,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1995/4067/report-thumb.jpg"},{"id":55944,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1995/4067/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"North Carolina","county":"Mecklenburg County","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-80.7823,35.5113],[-80.7867,35.5031],[-80.7889,35.4949],[-80.7831,35.4836],[-80.7819,35.475],[-80.7779,35.4668],[-80.7778,35.4614],[-80.7744,35.4578],[-80.7549,35.423],[-80.7525,35.4148],[-80.7553,35.4125],[-80.7638,35.4134],[-80.7693,35.402],[-80.7551,35.3944],[-80.7364,35.3786],[-80.7187,35.3624],[-80.704,35.3552],[-80.6983,35.3507],[-80.6822,35.3131],[-80.6677,35.2705],[-80.6214,35.2499],[-80.5954,35.2369],[-80.5485,35.2108],[-80.6245,35.1487],[-80.7328,35.0627],[-80.7645,35.0375],[-80.7684,35.0348],[-80.7746,35.0329],[-80.7858,35.0315],[-80.7892,35.0314],[-80.8009,35.0286],[-80.8155,35.0204],[-80.8194,35.019],[-80.8216,35.018],[-80.8216,35.0167],[-80.8288,35.0098],[-80.835,35.0061],[-80.8405,35.0016],[-80.8604,35.0246],[-80.8854,35.0535],[-80.9016,35.0716],[-80.9312,35.1049],[-80.9373,35.1018],[-81.0383,35.0452],[-81.0419,35.0432],[-81.0447,35.0468],[-81.0464,35.0482],[-81.0483,35.0507],[-81.0503,35.0527],[-81.0528,35.0557],[-81.0548,35.0582],[-81.0568,35.0611],[-81.0577,35.0636],[-81.0586,35.067],[-81.0582,35.0722],[-81.0577,35.0788],[-81.0566,35.0834],[-81.0554,35.0868],[-81.0541,35.0904],[-81.0533,35.0927],[-81.0523,35.0956],[-81.0503,35.0975],[-81.0487,35.099],[-81.0462,35.1003],[-81.0437,35.1014],[-81.042,35.1022],[-81.0391,35.1027],[-81.0369,35.1036],[-81.0352,35.1054],[-81.0344,35.1072],[-81.0341,35.1095],[-81.0341,35.1136],[-81.0358,35.1186],[-81.0363,35.1213],[-81.038,35.124],[-81.0408,35.1267],[-81.0425,35.1281],[-81.0454,35.1289],[-81.0476,35.1295],[-81.0499,35.1302],[-81.051,35.1313],[-81.0521,35.1335],[-81.0523,35.1365],[-81.0517,35.1392],[-81.0501,35.142],[-81.0476,35.1463],[-81.0448,35.1494],[-81.0238,35.1486],[-81.0176,35.1536],[-81.0109,35.1532],[-81.0076,35.1569],[-81.0088,35.165],[-81.0049,35.1728],[-81.0045,35.1814],[-81.0046,35.1864],[-81.0063,35.1923],[-81.0064,35.1973],[-81.0054,35.2055],[-81.0071,35.2109],[-81.0129,35.2231],[-81.0113,35.2309],[-81.012,35.2349],[-81.0082,35.2509],[-81.0139,35.2585],[-81.0152,35.2685],[-81.0143,35.2876],[-81.0133,35.293],[-81.0105,35.2944],[-81.0033,35.3017],[-81.0022,35.3045],[-80.9961,35.3113],[-80.9938,35.3132],[-80.9894,35.3205],[-80.9844,35.3237],[-80.9805,35.3287],[-80.9823,35.3341],[-80.984,35.3373],[-80.9818,35.3446],[-80.9706,35.3501],[-80.9656,35.3506],[-80.9593,35.3489],[-80.9537,35.3521],[-80.9442,35.3521],[-80.9374,35.3572],[-80.9285,35.3614],[-80.9268,35.3627],[-80.9296,35.3636],[-80.9432,35.3658],[-80.9505,35.3675],[-80.9563,35.3738],[-80.9597,35.3756],[-80.9625,35.3756],[-80.9647,35.3738],[-80.9669,35.3688],[-80.9697,35.3669],[-80.9742,35.3642],[-80.9776,35.3646],[-80.9844,35.3695],[-80.9868,35.38],[-80.9846,35.3822],[-80.9806,35.3823],[-80.9761,35.3828],[-80.9632,35.3901],[-80.9554,35.3925],[-80.9549,35.4006],[-80.959,35.4133],[-80.9569,35.4288],[-80.9587,35.436],[-80.9527,35.446],[-80.9465,35.4524],[-80.9421,35.457],[-80.9432,35.4602],[-80.9506,35.4656],[-80.9518,35.4701],[-80.948,35.481],[-80.947,35.486],[-80.951,35.4942],[-80.9612,35.4986],[-80.9664,35.509],[-80.9637,35.5131],[-80.9586,35.5163],[-80.9569,35.5177],[-80.7823,35.5113]]]},\"properties\":{\"name\":\"Mecklenburg\",\"state\":\"NC\"}}]}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adfe4b07f02db6879ca","contributors":{"authors":[{"text":"Ferrell, G.M.","contributorId":92681,"corporation":false,"usgs":true,"family":"Ferrell","given":"G.M.","email":"","affiliations":[],"preferred":false,"id":197513,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Smith, D.G.","contributorId":49393,"corporation":false,"usgs":true,"family":"Smith","given":"D.G.","email":"","affiliations":[],"preferred":false,"id":197512,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}} ,{"id":22434,"text":"ofr95450 -

These data were produced at the request of various individuals to provide needed subsurface-temperature data for their investigations. The fluid-inclusion information presented in this report has not been previously published, and, since the author did not work in these geothermal areas, only a very minimal attempt is made at interpreting the data. Information on the location of the drill holes from which the core specimens originated ranges from very poor in the case of the Russian drill holes to very good for those in the USA.
Mineral specimens from drill-core samples in the five geothermal areas were utilized as cleavage chips, thin sections polished on a single side, or double polished thin sections (polished on both sides). Fluid inclusions from all three USA geothermal areas were found in either hydrothermal or primary quartz crystals. These fluid inclusions firstly were frozen and gradually thawed to determine the final melting-point temperatures (Tm) as the last piece of ice melted and secondly, were heated to the temperature at which the vapor phase disappeared to obtain homogenization temperatures (Tn). For the El Salvador and Russian core specimens the fluid inclusions were hosted in calcite, and the order of the two procedures was reversed because calcite is a much softer mineral than quartz and there is a greater danger of the fluid inclusions decrepitating as the ice expands during freezing.
A Chaixmeca microthermometry apparatus was used during studies of the Steamboat Springs and The Geysers fluid inclusions. For the remaining studies, a Linkam THM 600 heating/freezing stage and TMS 90 temperature control system were employed. Accuracy of the data generated from both instruments is similar, with values of about ±2°C for heating studies and about ±0.2°C for the freezing methods.

The basin extends through four physiographic provinces in North Carolina and Virginia-Valley and Ridge, Blue Ridge, Piedmont and Coastal Plain. The spatial and temporal trends in ground-water and riverine water quality in the study area were characterized by using readily available data sources The primary data sources that were used included the U.S. Geological Survey's National Water Data Storage and Retrieval System (WATSTORE) database, the U.S. Environmental Protection Agency's Storage and Retrieval System (STORET) database, and results of a few investigations of pesticide occurrence. The principal water-quality constituents examined were suspended sediment, nutrients, and pesticides. The data examined generally spanned the period from 1950 to 1993.\r\n\r\nThe only significant trends in suspended sediment were detected at three Chowan River tributary sites which showed long-term decreases. Suspended- and total-solids concentrations have decreased throughout the Albemarle-Pamlico drainage basin. The decreases are probably a result of (1) construction of new lakes and ponds in the basin, which trap solids, (2) improved agricultural soil management, and (3) improved wastewater treatment. \r\n\r\nNutrient point sources are much less than nonpoint nutrient sources at the eight NASQAN basins examined for nutrient loads. The greatest nitrogen inputs are associated with crop fertilizer and biological nitrogen fixation by soybeans and peanuts, whereas atmospheric and animal-related nitrogen inputs are comparable in magnitude. The largest phosphorus inputs are associated with animal wastes.\r\n\r\nThe most commonly detected pesticides in surface water in the STORET database were atrazine and aldrin.Intensive organonitrogen herbicide sampling of Chicod Creek in 1992 showed seasonal variations in pesticide concentration. The most commonly detected herbicides were atrazine, alachlor, metolachlor, prometon, and metribuzin. No relation between streamflow and pesticide concentration was evident.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr95191","usgsCitation":"Harned, D., McMahon, G., Spruill, T., and Woodside, M.D., 1995, Water-quality assessment of the Albemarle-Pamlico drainage basin, North Carolina and Virginia: Characterization of suspended sediment, nutrients, and pesticides: U.S. Geological Survey Open-File Report 95-191, x, 131 p., https://doi.org/10.3133/ofr95191.","productDescription":"x, 131 p.","costCenters":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true}],"links":[{"id":51691,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1995/0191/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":154446,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1995/0191/report-thumb.jpg"},{"id":410401,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_18416.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"North Carolina, Virginia","otherGeospatial":"Albemarle-Pamlico drainage basin","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"coordinates\": [\n [\n [\n -80.406,\n 37.592\n ],\n [\n -80.406,\n 34.531\n ],\n [\n -75.281,\n 34.531\n ],\n [\n -75.281,\n 37.592\n ],\n [\n -80.406,\n 37.592\n ]\n ]\n ],\n \"type\": \"Polygon\"\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e5e4b07f02db5e7077","contributors":{"authors":[{"text":"Harned, Douglas","contributorId":11195,"corporation":false,"usgs":true,"family":"Harned","given":"Douglas","affiliations":[],"preferred":false,"id":187853,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"McMahon, Gerard 0000-0001-7675-777X gmcmahon@usgs.gov","orcid":"https://orcid.org/0000-0001-7675-777X","contributorId":191488,"corporation":false,"usgs":true,"family":"McMahon","given":"Gerard","email":"gmcmahon@usgs.gov","affiliations":[{"id":13634,"text":"South Atlantic Water Science Center","active":true,"usgs":true},{"id":565,"text":"Southeast Climate Science Center","active":true,"usgs":true}],"preferred":true,"id":187852,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Spruill, T.B.","contributorId":76747,"corporation":false,"usgs":true,"family":"Spruill","given":"T.B.","affiliations":[],"preferred":false,"id":187854,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Woodside, M.

Samples were \r\ncollected from 38 wells primarily from the Morrison aquifer (25 \r\nwells) in the northwestern part of the basin. A series of samples\r\nwas collected along ground-water flow paths; dissolved \r\nconstituents varied horizontally and vertically.\r\n\r\n The understanding of the flow system changed as a result of\r\nthe geochemical analyses. The conceptual model of the flow system in\r\nthe Morrison aquifer prior to the study reported here assumed the\r\nWestwater Canyon Member of the Morrison aquifer as the only \r\nsignificant regional aquifer; flow was assumed to be two \r\ndimensional; and vertical leakage was assumed to be negligible.\r\nThe geochemical results indicate that the Westwater Canyon Member\r\nis not the only major water-yielding zone and that the flow\r\nsystem is three dimensional. The data presented in this report \r\nsuggest an upward component of flow into the Morrison aquifer. The \r\nentire section above and below the Morrison aquifer appears to be \r\ncontrolled by a three-dimensional flow regime where saline brine\r\nleaks near the San Juan River discharge area.\r\n\r\n Predominant ions in the Gallup aquifer were calcium\r\nbicarbonate in recharge areas and sodium sulfate in discharge areas. \r\nIn the Dakota aquifer, predominant ions were sodium bicarbonate and\r\nsodium sulfate. Water in the Morrison aquifer was predominantly sodium \r\nbicarbonate in the recharge area, changing to sodium sulfate \r\ndowngradient.\r\n\r\n Chemical and radioisotopic data indicate that water from \r\noverlying and underlying units mixes with recharge water in the \r\nMorrison aquifer. Recharge water contained a large ratio of \r\nchlorine-36 to chlorine and a small ratio of bromide to chloride.\r\nApproximately 10 miles downgradient, samples from four wells \r\ncompleted in the Morrison aquifer were considerably different in\r\ncomposition compared to recharge samples. Oxygen stable isotopes\r\ndecreased by 2.8 per mil and deuterium decreased 26 per mil, \r\nrelative to recharge. Carbon-14 radioisotope activities were not\r\ndetectable. Chloride-36 radioisotope ratios were small and\r\nbromide to chloride concentration ratios were large. These results\r\nsuggest two potentially viable processes: ion filtration or trapping of\r\nancient dilute water recharged under a humid climate. For water\r\nsamples near the San Juan River, pH decreased to about 8.0, \r\nchloride concentrations increased to more than 100 milligrams per\r\nliter, and ratios of chlorine-36 to chlorine and bromide to \r\nchloride were small. Leakage of deep basin brine into the fresher\r\nwater of the Morrison aquifer appears to control ion concentrations.","language":"ENGLISH","publisher":"U.S. Geological Survey, [Water Resources Division, New Mexico District] ;\r\nCan be purchased from U.S.G.S.

To enhance visitor safety and to protect cultural and natural resources, the U.S. Geological Survey in cooperation with the National Park Service studied flood-hazard potentials within the boundaries of the Pinnacles National Monument. This study area extends from about a quarter of a mile north of Chalone Creek Campground to the mouth of Bear Valley and from the east monument entrance to Chalone Creek. Historical data of precipitation and floodflow within the monument area are sparse to nonexistent, therefore, U.S. Soil Conservation Service unit-hydrograph procedures were used to determine the magnitude of a 100-year flood. Because of a lack of specific storm-rainfall data, a simulated storm was applied to the basins using a digital-computer model developed by the Soil Conservation Service. A graphical relation was used to define the regionally based maximum flood for Chalone Creek and Bear Valley. Water-surface elevations and inundation areas were determined using a conventional step-backwater program. Flood-zone boundaries were derived from the computed water-surface elevations. The 100-year flood plain for both streams would be inundated at all points by the regional maximum flood. Most of the buildings and proposed building sites in the monument area are above the elevation of the 100-year flood, except the proposed building sites near the horse corral and the east monument entrance. The 100-year flood may cause reverse flow through a 12-inch culvert embedded in the embankment of Old Pinnacles Campground Road in the center of Chalone Creek Campground. The likelihood of this occurring is dependant upon the amount of aggradation that occurs upstream; therefore, the campground area also is considered to be within the 100-year flood zone.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nEarth Science Information Center, Open-File Reports Section [distributor],","doi":"10.3133/ofr95426","issn":"0094-9140","usgsCitation":"Meyer, R.W., 1995, Potential hazards from flood in part of the Chalone Creek and Bear Valley drainage basins, Pinnacles National Monument, California: U.S. Geological Survey Open-File Report 95-426, iv, 23 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr95426.","productDescription":"iv, 23 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":156539,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1995/0426/report-thumb.jpg"},{"id":19487,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1995/0426/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":19488,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1995/0426/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad4e4b07f02db6832d8","contributors":{"authors":[{"text":"Meyer, Robert W.","contributorId":69601,"corporation":false,"usgs":true,"family":"Meyer","given":"Robert","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":190907,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":24694,"text":"ofr95387 - 1995 - Status of ground-water resources at U.S. Navy Support Facility, Diego Garcia; summary of hydrologic and climatic data, January 1992 through December 1994","interactions":[],"lastModifiedDate":"2012-02-02T00:08:28","indexId":"ofr95387","displayToPublicDate":"1996-06-01T00:00:00","publicationYear":"1995","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"95-387","title":"Status of ground-water resources at U.S. Navy Support Facility, Diego Garcia; summary of hydrologic and climatic data, January 1992 through December 1994","docAbstract":"This report contains hydrologic and climatic data that describe the status of ground-water resources at U.S. Navy Support Facility, Diego Garcia. Data presented are from January 1992 through December 1994. This report concentrates on data from October through December 1994, and references previous data from 1992 through 1994. Cumulative rainfall for October through December 1994 was 55 inches which is higher than the mean cumulative rainfall of about 31 inches for the same 3 months. Total rainfall for 1994 was 131 inches which is 24 percent higher than the mean annual rainfall of 106 inches. In com- parison, total rainfall in 1992 and 1993 were 93 inches and 95 inches, respectively. Ground-water withdrawal during October through December 1994 averaged 903,000 gallons per day, while the annual withdrawal in 1994 was 942,700 gallons per day. Annual withdrawals in 1992 and 1993 averaged 935,900 gallons per day and 953,800 gallons per day, respectively. At the end of December 1994, the chloride concentration of the composite water supply was 28 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 1994 ranged between 28 and 86 milligrams per liter. Chloride concentration of ground water in monitoring wells at Cantonment and Air Operations decreased in November and December, and seems to have leveled off by the end of the year. Although chloride concen- trations have decreased during the fourth quarter of 1994, there has been a general trend of increasing chloride concentrations in the deeper monitoring wells since the 1992 dry season, which began in March 1992. 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 contain and divert fuel migration by recirculating 150,000 gallons of water each day.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nFor sale by the Earth Science Information Center, Open-File Reports Section,","doi":"10.3133/ofr95387","issn":"0094-9140","usgsCitation":"Torikai, J., 1995, Status of ground-water resources at U.S. Navy Support Facility, Diego Garcia; summary of hydrologic and climatic data, January 1992 through December 1994: U.S. Geological Survey Open-File Report 95-387, v, 42 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr95387.","productDescription":"v, 42 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":157821,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1995/0387/report-thumb.jpg"},{"id":53727,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1995/0387/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699e54","contributors":{"authors":[{"text":"Torikai, J.D.","contributorId":93926,"corporation":false,"usgs":true,"family":"Torikai","given":"J.D.","affiliations":[],"preferred":false,"id":192397,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":22282,"text":"ofr95391 - 1995 - Water-resources activities of the U.S. Geological Survey in Illinois, 1994","interactions":[],"lastModifiedDate":"2012-02-02T00:08:02","indexId":"ofr95391","displayToPublicDate":"1996-06-01T00:00:00","publicationYear":"1995","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":330,"text":"Open-File Report","code":"OFR","onlineIssn":"2331-1258","printIssn":"0196-1497","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"95-391","title":"Water-resources activities of the U.S. Geological Survey in Illinois, 1994","docAbstract":"This report gives an overview of U.S. Geological Survey, Illinois District, Water Resources Division activities related to the water resources of the State of Illinois.

Summary statistics and graphical comparisons of the data show substantial variability in the properties during 1986-91. Specific conductance ranged from about 100 microsiemens per centimeter at 25 degrees Celsius at each of the three sites to 17,100 microsiemens per centimeter at 25 degrees Celsius at the most downstream site, at the headwaters of the Houston Ship Channel. Water temperatures ranged from 5 to 33 degrees Celsius. Temperatures were very similar at the two upstream sites and slightly warmer at the most downstream site. Dissolved oxygen ranged from zero at the most downstream site to 11.7 milligrams per liter at the most upstream site.

Chemical and isotopic compositions were measured for six N-source types consisting of rain water, forest-leaf litter, synthetic fertilizer, farm-animal manure, municipal-sewage effluent and sludge, and septic-tank effluent and sludge. Compositions of topsoil, subsoil, runoff water, and stream water were measured to evaluate changes in compositions of transported N-containing materials near the N source. Animal manure, human waste (sewage plus septic), and forest-leaf litter can be distinguished on the basis of C; however, most N-sources can not be distinguished on the basis of N and S, owing to wide ranges of compositions and overlap among different N-source types. Although values of N for soil and runoff-water samples are qualitatively similar to those of the applied N source, values of C and S for runoff-water and stream-water samples appear to reflect the compositions of relatively large reservoirs of the elements in soil organic matter and minerals, respectively, and not the composition of the applied N source. Because of incomplete chemical transfor- mations, the ratio of organic carbon to total nitrogen for particulates in runoff or stream waters generally is lower than that for associated, nearby soils, and isotopic compositions commonly differ between particulate and dissolved fractions in the water.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr94510","issn":"0094-9140","usgsCitation":"Cravotta, C., 1995, Use of stable isotopes of carbon, nitrogen, and sulfer to identify sources of nitrogen in surface waters in the Lower Susquehanna River basin, Pennsylvania: U.S. Geological Survey Open-File Report 94-510, vi, 103 p. :ill., map ;28 cm., https://doi.org/10.3133/ofr94510.","productDescription":"vi, 103 p. :ill., map ;28 cm.","costCenters":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"links":[{"id":156452,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1994/0510/report-thumb.jpg"},{"id":52217,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1994/0510/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ee4b07f02db5fdcba","contributors":{"authors":[{"text":"Cravotta, C.A.

Northern Lake County is on the southern shore of Lake Michigan and includes the cities of East Chicago, Gary, Hammond, and Whiting. The study area is underlain by the unconfined Calumet aquifer and receives about 36 inches of precipitation per year.
\nThe U.S. Geological Survey investigated ground-water levels and flow in the Calumet aquifer and the effect of Lake Michigan levels on ground-water and surface-water levels throughout the study area. Summary statistics of the water-level data were computed for each site.
\nGround-water levels annually reach a maximum in June or July and a minimum in September or October. Measured groundwater fluctuations in the Calumet aquifer during the study period ranged from 0.40 to 5.01 feet, and the mean ground-water fluctuation was about 2.3 feet The largest surface-water fluctuations were affected by record setting Lake Michigan levels. Midmonth daily averages for the data-collection period show that Lake Michigan fluctuated 4.14 feet Water-level fluctuations on the Grand Calumet River were from 1.06 to 2.45 feet.
\nAnalysis of water-level data indicates that the 1988 drought did not substantially affect water levels in the Calumet aquifer, but the deficit in precipitation reversed vertical flow gradients in ground water at three paired deep and shallow wells. High water levels in Lake Michigan during 1985-87 created long-term backwater effects on the Grand Calumet River as far as 11.0 miles upstream from Lake Michigan.
\nAnalysis of water-level data from the data-collection network indicates that the water table normally slopes toward streams, ditches, sewers, the Indiana Harbor Canal, and Lake Michigan. The slope of the water table toward the Grand Calumet River is greatest in the winter and can decrease to being almost horizontal in the summer. Wells near streams respond quickly to nearby surface-water-level changes. Water-table maps indicate that sewers and dewatering systems are lowering ground-water levels in large areas. Ditches, the Grand Calumet River, and the Indiana Harbor Canal connect the Lake Michigan water level to large parts of the study area. The surface-water stage in the Indiana Harbor Canal, which functions as a ditch, can equal Lake Michigan's stage up to 3.75 miles inland from the lakeshore. Human activity, the stage of Lake Michigan, and the storage capacity of the Calumet aquifer combine to reduce vertical changes in the water table in the study area.

Total mean densities of benthic macroinvertebrates for the three sites ranged from 670 to 10,000 organisms per square meter. The most abundant macroinvertebrates were the class Insecta (insects). Total densities of periphyton ranged from 2,900 to 110,000 cells per square millimeter. Cyanophyta (blue-green algae) and Bacillariophyta (diatoms) were the predominant periphyton organisms. Total densities of phyto- plankton ranged from 5,000 to 47,000 cells per square milliliter. Blue-green algae accounted for more than one- half of the phytoplankton in each sample. Hardness ranged from 160 to 250 milligrams per liter as calcium carbonate, and alkalinity ranged from 130 to 220 milligrams per liter as calcium carbonate. The largest dissolved nitrite concentration was 0.038 milligram per liter. The largest total phosphorus concentration was 0.150 milligram per liter, over one-half of which was dissolved orthophosphate. Total aluminum and total iron were the only trace elements in water to exceed the reporting threshold by large concen- trations. Total aluminum concentrations ranged from 70 to 280 micrograms per liter, and total iron concentrations ranged from 70 to 340 micrograms per liter.
