The RFI has found trichloroethene, dichloroethene, vinyl chloride, as well as chromium, lead, and other metallic residuum in the shallow alluvial aquifer underlying NWIRP. </p><p>These findings and the possibility of on-site or off-site migration of contaminants prompted the need for a ground-water-flow model of the NWIRP area. The resulting U.S. Geological Survey (USGS) model: (1) defines aquifer properties, (2) computes water budgets, (3) delineates major flowpaths, and (4) simulates hydrologic effects of remediation activity. In addition to assisting with particle-tracking analyses, the calibrated model could support solute-transport modeling as well as help evaluate the effects of potential corrective action. The USGS model simulates steadystate and transient conditions of ground-water flow within a single model layer.</p><p>The alluvial aquifer is within fluvial terrace deposits of Pleistocene age, which unconformably overlie the relatively impermeable Eagle Ford Shale of Late Cretaceous age. Over small distances and short periods, finer grained parts of the aquifer are separated hydraulically; however, most of the aquifer is connected circuitously through randomly distributed coarser grained sediments. The top of the underlying Eagle Ford Shale, a regional confining unit, is assumed to be the effective lower limit of ground-water circulation and chemical contamination.</p><p>The calibrated steady-state model reproduces long-term average water levels within +5.1 or –3.5 feet of those observed; the standard error of the estimate is 1.07 feet with a mean residual of 0.02 foot. Hydraulic conductivity values range from 0.75 to 7.5 feet per day, and average about 4 feet per day. Specific yield values range from 0.005 to 0.15 and average about 0.08. Simulated infiltration rates range from 0 to 2.5 inches per year, depending mostly on local patterns of ground cover.</p><p>Computer simulation indicates that, as of December 31, 1998, remediation systems at NWIRP were removing 7,375 cubic feet of water per day from the alluvial aquifer, with 3,050 cubic feet per day coming from aquifer storage. The resulting drawdown prevented 1,800 cubic feet per day of ground water from discharging into Cottonwood Bay, as well as inducing another 1,325 cubic feet per day into the aquifer from the bay. An additional 1,200 cubic feet of water per day (compared to pre-remediation conditions) was prevented from discharging into the west lagoon, east lagoon, Mountain Creek Lake, and Mountain Creek swale.</p><p>Particle-tracking simulations, assuming an aquifer porosity of 0.15, were made to delineate flowpath patterns, or contaminant “capture zones,” resulting from 2.5- and 5-year periods of remediation activity at NWIRP. The resulting flowlines&nbsp;indicate three such zones, or areas from which ground water is simulated to have been removed during July 1996–December 1998, as well as extended areas from which ground water <i>would be</i> removed during the <i>next</i> 2.5 years (January 1999– June 2001).</p><p>Simulation indicates that, as of December 31, 1998, the recovery trench was intercepting about 827 cubic feet per day of ground water that—without the trench—would have discharged into Cottonwood Bay. During this time, the trench is simulated to have removed about 3,221 cubic feet per day of water from the aquifer, with about 934 cubic feet per day (29 percent) coming from the south (Cottonwood Bay) side of the trench.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri004197","collaboration":"In cooperation with the Department of the Navy, Southern Division Naval Facilities Engineering Command","usgsCitation":"Barker, R.A., and Braun, C.L., 2000, Computer-model analysis of ground-water flow and simulated effects of contaminant remediation at Naval Weapons Industrial Reserve Plant, Dallas, Texas: U.S. Geological Survey Water-Resources Investigations Report 2000-4197, HTML Document; Report: v, 44 p.; 2 Plates: 36.5 x 28 inches and 18 x 18.5 inches, https://doi.org/10.3133/wri004197.","productDescription":"HTML Document; Report: v, 44 p.; 2 Plates: 36.5 x 28 inches and 18 x 18.5 inches","costCenters":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"links":[{"id":161442,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri004197.JPG"},{"id":2782,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/wri/wri004197/","linkFileType":{"id":5,"text":"html"}},{"id":333097,"rank":4,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/wri004197/pdf/00-4197.pdf","text":"Report","size":"2.57 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"},{"id":333098,"rank":5,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/wri004197/pdf/pl2.pdf","text":"Plate 2","size":"617 KB","linkFileType":{"id":1,"text":"pdf"},"description":"Plate 2"},{"id":333099,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/wri004197/pdf/pl1.pdf","text":"Plate 1","size":"578 KB","linkFileType":{"id":1,"text":"pdf"},"description":"Plate 1"}],"country":"United States","state":"Texas","city":"Dallas","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -96.73187255859375,\n              32.560703522325156\n            ],\n            [\n              -96.9873046875,\n              32.56764789050999\n            ],\n            [\n              -97.5,\n              32.6\n            ],\n            [\n              -97.53387451171875,\n              32.80112754111693\n            ],\n            [\n              -97.470703125,\n              32.99484290420988\n            ],\n            [\n              -96.86920166015625,\n              33.23639027157906\n            ],\n            [\n              -96.59454345703125,\n              33.24098472320831\n            ],\n            [\n              -96.5,\n              33\n            ],\n            [\n              -96.52313232421875,\n              32.62087018318113\n            ],\n            [\n              -96.73187255859375,\n              32.560703522325156\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b19e4b07f02db6a75be","contributors":{"authors":[{"text":"Barker, Rene A.","contributorId":82669,"corporation":false,"usgs":true,"family":"Barker","given":"Rene","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":204246,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Braun, Christopher L. 0000-0002-5540-2854 clbraun@usgs.gov","orcid":"https://orcid.org/0000-0002-5540-2854","contributorId":925,"corporation":false,"usgs":true,"family":"Braun","given":"Christopher","email":"clbraun@usgs.gov","middleInitial":"L.","affiliations":[{"id":48595,"text":"Oklahoma-Texas Water Science Center","active":true,"usgs":true}],"preferred":true,"id":204245,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Low-flow frequencies at low-flow partial-record stations were estimated by relating base-flow measurements to concurrent daily flows at nearby streamflow-gaging stations (index stations) for which low-flow- frequency curves had been developed. A network of long-term streamflow-gaging stations in Indiana provided a sample of sites with observed low-flow frequencies.Observed values of 7-day, 10-year low flow and 7-day, 2-year low flow were compared to predicted values to evaluate the accuracy of the method.</p><p>Five test cases were used to evaluate the method under a variety of conditions in which the location of the index station and its drainage area varied relative to the partial-record station. A total of 141 pairs of streamflow-gaging stations were used in the five test cases. Four of the test cases used one index station, the fifth test case used two index stations. The number of base-flow measurements was varied for each test case to see if the accuracy of the method was affected by the number of measurements used.</p><p>The most accurate and least variable results were produced when two index stations on the same stream or tributaries of the partial-record station were used. All but one value of the predicted 7-day, 10-year low flow were within 15 percent of the values observed for the long-term continuous record, and all of the predicted values of the 7-day, 2-year low-flow were within 15 percent of the observed values. This apparent accuracy, to some extent, may be a result of the small sample set of 15.</p><p>Of the four test cases that used one index station, the most accurate and least variable results were produced in the test case where the index station and partial-record station were on the same stream or on streams tributary to each other and where the index station had a larger drainage area than the partial-record station. In that test case, the method tended to over predict, based on the median relative error. In 23 of 28 test pairs, the predicted 7-day, 10-year low flow was within 15 percent of the observed value; in 26 of 28 test pairs, the predicted 7-day, 2-year low flow was within 15 percent of the observed value.</p><p>When the index station and partial- record station were on the same stream or streams tributary to each other and the index station had a smaller drainage area than the partial-record station, the method tended to under predict the low-flow frequencies. Nineteen of 28 predicted values of the 7-day, 10-year low-flow were within 15 percent of the observed values. Twenty-five of 28 predicted values of the 7-day, 2-year low flow were within 15 percent of the observed values.</p><p>When the index station and the partial- record station were on different streams, the method tended to under predict regardless of whether the index station had a larger or smaller drainage area than that of the partial-record station. Also, the variability of the relative error of estimate was greatest for the test cases that used index stations and partial-record stations from different streams. This variability, in part, may be caused by using more streamflow-gaging stations with small low-flow frequencies in these test cases. A small difference in the predicted and observed values can equate to a large relative error when dealing with stations that have small low-flow frequencies.</p><p>In the test cases that used one index station, the method tended to predict smaller low-flow frequencies as the number of base- flow measurements was reduced from 20 to 5. Overall, the average relative error of estimate and the variability of the predicted values increased as the number of base-flow measurements was reduced.</p>","language":"English","publisher":"U.S.

From each of these six wells, a \r\nwell-bore flow log was collected that represents the cumulative \r\nupward well-bore flow. Evaluation of the well-bore flow log for each \r\nwell allowed delineation of the more productive zones supplying \r\nwater to the well along the logged interval.\r\n\r\nYields from the more productive zones in the six wells \r\nranged from about 70 to 880 gallons per minute.

Physical data include water temperature, instantaneous stream discharge, pH, alkalinity, specific conductance, and dissolved oxygen. Chemical data collected include laboratory determinations of nutrients and major ions in whole water samples and selected metals, pesticides, gross polychlorinated biphenyls (PCB's), gross polychlorinated napthalenes (PCN's), and total carbon in stream-sediment samples. The biological data include benthic-macroinvertebrate populations.

The samples were analyzed for volatile organic compounds, including trichloroethylene, 1,1,2,2-tetrachloroethane, carbon tetrachloride, and chloroform, which are the four major contaminants that were detected in ground water in the Canal Creek area in earlier USGS studies. Field blanks were collected during the sampling period to assess sample bias. Field replicates were used to assess sample variability, which was expressed as relative percent difference. The mean variability of the surface-water replicate analyses was larger (35.4 percent) than the mean variability of ground-water replicate analyses (14.6 percent) determined for West Branch Canal Creek from 1995 through 1996. The higher variability in surface-water analyses is probably due to heterogeneities in the composition of the surface water rather than differences in sampling or analytical procedures. The most frequently detected volatile organic compound was 1,1,2,2- tetrachloroethane, which was detected in every sample and in two of the replicates. The surface-water contamination is likely the result of cross-media transfer of contaminants from the ground water and sediments along the West Branch Canal Creek. The full extent of surface-water contamination in West Branch Canal Creek and the locations of probable contaminant sources cannot be determined from this limited set of data. Tidal mixing, creek flow patterns, and potential effects of a drought that occurred during the sampling period also complicate the evaluation of surface-water contamination.","language":"ENGLISH","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey ;\r\nBranch of Information Services [distributor],","doi":"10.3133/ofr00203","issn":"0094-9140","usgsCitation":"Olsen, L., and Spencer, T.A., 2000, Assessment of volatile organic compounds in surface water at West Branch Canal Creek, Aberdeen Proving Ground, Maryland, 1999: U.S. Geological Survey Open-File Report 2000-203, iv, 15 p. :maps ;28 cm., https://doi.org/10.3133/ofr00203.","productDescription":"iv, 15 p. :maps ;28 cm.","costCenters":[],"links":[{"id":156830,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":1753,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2000/ofr00203/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aa8e4b07f02db6674df","contributors":{"authors":[{"text":"Olsen, Lisa D. ldolsen@usgs.gov","contributorId":2707,"corporation":false,"usgs":true,"family":"Olsen","given":"Lisa D.","email":"ldolsen@usgs.gov","affiliations":[{"id":509,"text":"Office of the Associate Director for Water","active":true,"usgs":true}],"preferred":true,"id":191296,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Spencer, Tracey A.","contributorId":59477,"corporation":false,"usgs":true,"family":"Spencer","given":"Tracey","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":191297,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The geologic map has been compiled at a scale of 1:100,000 from the most widely available sources of geologic map information (see index to geologic mapping on pl. 1). That information has been updated by M.W. Reynolds for this report with more recent geologic mapping and field revision of published maps. All well locations and all bedrock units penetrated during drilling have been confirmed on geologic maps at the largest scale available. Source geologic maps are all at scales larger than 1:100,000 scale. Care has been taken to ensure accurate representation of the original geology at the compilation scale. However, positional accuracy of some features might be somewhat diminished at the smaller scale of the base map when compared with the original data source. Also, line thicknesses for contacts and faults necessarily assume a greater width, relative to the real geologic feature, at the scale of the generalized map than on any original map. The map is not intended for large-scale, site-specific detailed planning.\r\n\r\nBedrock units throughout the Helena area are generally covered by young surficial deposits such as alluvium, colluvium, glacial debris, or windblown sediment. Thickness of such deposits varies from veneers through which the underlying bedrock is clearly discernible to major thicknesses that conceal all underlying bedrock and structure. Boundaries of major accumulations of surficial deposits are attributed separately from bedrock contacts. These boundaries should not be considered precise at the map scale or at larger scales. Boundaries shown may be less accurate positionally than bedrock contacts and faults because (1) surficial deposits commonly thin to a knife edge; (2) different mappers will interpret the edge differently when drawing a boundary; or (3) the original geologic map maker was concerned principally with bedrock units and structure and thus overlooked, or did not originally map as consistently, some surficial deposits. Veneers of surficial sediment, when saturated, can be local sources of recharge to underlying bedrock. Use of the generalized map to define their distribution does not substitute for site specific mapping of such deposits.\r\n\r\nSpecific knowledge is needed to determine the water-bearing properties of the geologic units at and surrounding a site because the units, including the igneous and metamorphic rocks, have internal differences in stratigraphy, composition, mineralogy and grain size or crystallinity. These differences, together with structural imprints such as faults, folds, and the spacing, orientation, degree of openness of fractures, and extent and type of mineral filling in fractures and faults, all affect the ability of rocks to store and transmit water.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri20004212","collaboration":"Prepared in cooperation with the Lewis and Clark County Water Quality Protection District","usgsCitation":"Thamke, J., and Reynolds, M.W., 2000, Hydrology of the Helena area bedrock, west-central Montana, 1993-98: U.S. Geological Survey Water-Resources Investigations Report 2000-4212, HTML Document, https://doi.org/10.3133/wri20004212.","productDescription":"HTML Document","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":400,"text":"Montana Water Science Center","active":false,"usgs":true}],"links":[{"id":110140,"rank":700,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_34501.htm","linkFileType":{"id":5,"text":"html"},"description":"34501"},{"id":159162,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":2373,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/wri/wri-00-4212/","linkFileType":{"id":5,"text":"html"}}],"scale":"100000","projection":"Universal Transverse Mercator","country":"United States","state":"Montana","otherGeospatial":"Helena area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -112.368,\n              46.393\n            ],\n            [\n              -111.787,\n              46.393\n            ],\n            [\n              -111.787,\n              46.791\n            ],\n            [\n              -112.368,\n              46.7951\n            ],\n            [\n              -112.368,\n              46.393\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ee4b07f02db5fe185","contributors":{"authors":[{"text":"Thamke, Joanna N. 0000-0002-6917-1946 jothamke@usgs.gov","orcid":"https://orcid.org/0000-0002-6917-1946","contributorId":1012,"corporation":false,"usgs":true,"family":"Thamke","given":"Joanna N.","email":"jothamke@usgs.gov","affiliations":[{"id":493,"text":"Office of Ground Water","active":true,"usgs":true},{"id":5050,"text":"WY-MT Water Science Center","active":true,"usgs":true}],"preferred":true,"id":202673,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Reynolds, Mitchell W. 0000-0002-9966-3896 mwreynol@usgs.gov","orcid":"https://orcid.org/0000-0002-9966-3896","contributorId":4641,"corporation":false,"usgs":true,"family":"Reynolds","given":"Mitchell","email":"mwreynol@usgs.gov","middleInitial":"W.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":202674,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The surface-water method uses \r\nstreamflow measurements and their differences along a stream reach, \r\nstreamflow-loss rates, stream surface area, and evaporation \r\nrates to determine infiltration rates. The ground-water method \r\nuses heat as a tracer to monitor percolation through shallow \r\nstreambed sediments. \r\n\r\nData collection began in October 1996 and continued through \r\nDecember 1997. During that period the stream reach was instrumented \r\nwith three streamflow gages, and temperature profiles were \r\nmonitored from the stream-sediment interface to about 3 meters below \r\nthe streambed at four sites along the reach.\r\n\r\nInfiltration is the downward flow of water through the stream-\r\nsediment interface. Infiltration rates ranged from 92 to 267 \r\nmillimeters per day for an intense measurement period during June 26-\r\n28, 1997, and from 69 to 256 millimeters per day during \r\nSeptember 27-October 6, 1997. Investigators calculated \r\ninfiltration rates from streamflow loss, stream surface-area \r\nmeasurements, and evaporation-rate estimates. Infiltration rates \r\nmay be affected by unmeasured irrigation-return flow in the \r\nstudy reach. Although the amount of irrigation-return flow was none \r\nto very small, it may result in underestimation of infiltration \r\nrates. The infiltration portion of streamflow loss was much greater \r\nthan the evaporation portion. Infiltration accounted for about \r\n92 to 98 percent of streamflow loss. Evaporation-rate estimates \r\nranged from 3.4 to 7.6 millimeters per day based on pan-evaporation \r\ndata collected at Cochiti Dam, New Mexico, and accounted for about 2 \r\nto 8 percent of streamflow loss.\r\n\r\nPercolation is the movement of water through saturated or \r\nunsaturated sediments below the stream-sediment interface. \r\nPercolation rates ranged from 40 to 109 millimeters per day during \r\nJune 26-28, 1997. Percolation rates were not calculated for the \r\nSeptember 27-October 6, 1997, period because a late summer flood \r\nremoved the temperature sensors from the streambed. Investigators \r\nused a heat-and-water flow model, VS2DH (variably saturated, two-\r\ndimensional heat), to calculate near-surface streambed \r\ninfiltration and percolation rates from temperatures measured in the \r\nstream and streambed.\r\n\r\nNear the stream-sediment interface, infiltration and \r\npercolation rates are comparable. Comparison of infiltration and \r\npercolation rates showed that infiltration rates were greater \r\nthan percolation rates. The method used to calculate infiltration \r\nrates accounted for net loss or gain over the entire stream reach, \r\nwhereas the method used to calculate percolation was \r\ndependent on point measurements and, as applied in this study, \r\nneglected the nonvertical component of heat and water \r\nfluxes. In general, using the ground-water method was less labor \r\nintensive than making a series of streamflow measurements and relied \r\non temperature, an easily measured property. The ground-water method \r\nalso eliminated the difficulty of measuring or estimating \r\nevaporation from the water surface and was therefore more direct. \r\nBoth methods are difficult to use during periods of flood flow. The \r\nground-water method has problems with the thermocouple-wire \r\ntemperature sensors washing out during flood events. The surface-\r\nwater method often cannot be used because of safety concerns for \r\npersonnel making wading streamflow measurements.","language":"English","publisher":"U.S. Geological Survey ","doi":"10.3133/wri004141","usgsCitation":"Thomas, C.L., Stewart, A.E., and Constantz, J.E., 2000, Determination of infiltration and percolation rates along a reach of the Santa Fe River near La Bajada, New Mexico: U.S. Geological Survey Water-Resources Investigations Report 2000-4141, iv, 65 p. , https://doi.org/10.3133/wri004141.","productDescription":"iv, 65 p.

Movements from 1997 to 1999 are less than 1 cm or within the error of measurement.","language":"English","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr00205","usgsCitation":"Varnes, D., Coe, J.A., Godt, J., Savage, W.Z., and Savage, J.E., 2000, Measurement of ridge-spreading movements (Sackungen) at Bald Eagle Mountain, Lake County, Colorado, II: Continuation of the 1975-1989 measurements using a Global Positioning System in 1997 and 1999: U.S. Geological Survey Open-File Report 2000-205, 23 p., https://doi.org/10.3133/ofr00205.","productDescription":"23 p.","costCenters":[],"links":[{"id":396277,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_26321.htm"},{"id":51410,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2000/0205/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":1280,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2000/ofr-00-0205/","linkFileType":{"id":5,"text":"html"}},{"id":155891,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2000/0205/report-thumb.jpg"}],"country":"United States","state":"Colorado","county":"Lake County","otherGeospatial":"Bald Eagle Mountain","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -106.48944854736328,\n              39.229327808005706\n            ],\n            [\n              -106.42112731933594,\n              39.229327808005706\n            ],\n            [\n              -106.42112731933594,\n              39.273992339346364\n            ],\n            [\n              -106.48944854736328,\n              39.273992339346364\n            ],\n            [\n              -106.48944854736328,\n              39.229327808005706\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a28e4b07f02db6111bc","contributors":{"authors":[{"text":"Varnes, David J.","contributorId":86322,"corporation":false,"usgs":true,"family":"Varnes","given":"David J.","affiliations":[],"preferred":false,"id":186312,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Coe, J.

Water samples were filtered to remove suspended-particulate matter and pumped through C-8 solid-phase extraction cartridges to extract the pesticides. The cartridges were dried with carbon dioxide and the pesticides were eluted with three cartridge volumes of hexane:diethyl ether (1:1) solution. The eluants were analyzed using capillary-column gas chromatography/mass spectrometry in full-scan mode. Method detection limits for pesticides ranged from 0.002 to 0.025 microgram per liter for 1-liter samples. Recoveries ranged from 44 to 140 percent for 25 pesticides in samples of organic-free reagent water and Sacramento-San Joaquin Delta and Suisun Bay water fortified at 0.05 and 0.50 microgram per liter. The estimated holding time for pesticides after extraction on C-8 solid-phase extraction cartridges ranged from 10 to 257 days.","language":"English","publisher":"U.S. Geological

Also, an air-temperature index for multiple landslide events is identified, and in conjunction with the precipitation thresholds, is used to develop a method for anticipating the occurrence of landslides during the December-March wet season. \r\n\r\nThe precipitation thresholds are based on 3-day cumulative precipitation that occurred immediately prior to landslide events and antecedent 15-day precipitation that occurred prior to the 3-day amounts. The data indicate that 15-day cumulative precipitation influences the amount of subsequent 3-day precipitation required to initiate landslides.\r\n\r\nResults of the analysis also indicate that air-temperature data can be used to help identify times when conditions are conducive for the initiation of landslides. It is shown that a high percentage of precipitation-related landslides occurred on days when the daily maximum air temperature was between 46? and 56? F (9? and 13? C) and that nearly all of the slides occurred on days when the daily maximum air temperature was above 43? F (6?

All streamflow-gaging stations used in the development of the equations had 10 or more years of record and include active and discontinued continuous-record and crest-stage partial-record streamflow-gaging stations. Regional regression equations were developed for flood flows expected every 10, 25, 50, 100, and 500 years by the use of a weighted multiple linear regression model.</p><p>The State was divided into two regions. The largest region, Region A, encompasses about 78 percent of Pennsylvania. The smaller region, Region B, includes only the northwestern part of the State. Basin characteristics used in the regression equations for Region A are drainage area, percentage of forest cover, percentage of urban development, percentage of basin underlain by carbonate bedrock, and percentage of basin controlled by lakes, swamps, and reservoirs.

Fresh ground water is obtained from shallow wells that tap the surface of a freshwater lends found in an aquifer composed mainly of coralline limestone. The main water-supply well withdraws water with a chloride concentration ranging from 160 to 220 mg/L. Current (1999) pumping rates adequately supply the island residents but future demand are expected to be higher.. To better understand the ground-water resources of the island and to learn more about the hydrology of oceanic islands, the U.S. Geological Survey (USGS) entered into a cooperative study with the Municipality of Tinian. The objective of the study, conducted between 1990 and 1997, was to assess the ground-water resources of the is;land. This report presents some of the results of the study including a description of the island's geology and geography, the current land use, the water-production system, the thickness and arcal extent of the freshwater lens, the water-table configuration and directions of ground-water flow. The report also discusses the relation of the changes in water-table elevation to daily and seasonal changes in ocean level.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri004068","usgsCitation":"Gingerich, S.B., and Yeatts, D.S., 2000, Ground-water resources of Tinian, Commonwealth of the Northern Mariana Islands: U.S. Geological Survey Water-Resources Investigations Report 2000-4068, 2 Plates: 32.86 x 32.62 and 33.08 x 32.55 inches, https://doi.org/10.3133/wri004068.","productDescription":"2 Plates: 32.86 x 32.62 and 33.08 x 32.55 inches","costCenters":[],"links":[{"id":160293,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri004068.PNG"},{"id":279491,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/2000/4068/plate-1.pdf"},{"id":279492,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/2000/4068/plate-2.pdf"},{"id":397737,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_31434.htm"}],"scale":"47600","country":"Commonwealth of the Northern Mariana Islands","otherGeospatial":"Tinian Island","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              145.5739974975586,\n              14.91492891904192\n            ],\n            [\n              145.6848907470703,\n              14.91492891904192\n            ],\n            [\n              145.6848907470703,\n              15.110244030251552\n            ],\n            [\n              145.5739974975586,\n              15.110244030251552\n            ],\n            [\n              145.5739974975586,\n              14.91492891904192\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a9ae4b07f02db65d590","contributors":{"authors":[{"text":"Gingerich, Stephen B. 0000-0002-4381-0746 sbginger@usgs.gov","orcid":"https://orcid.org/0000-0002-4381-0746","contributorId":1426,"corporation":false,"usgs":true,"family":"Gingerich","given":"Stephen","email":"sbginger@usgs.gov","middleInitial":"B.","affiliations":[{"id":525,"text":"Pacific Islands Water Science Center","active":true,"usgs":true},{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true}],"preferred":true,"id":204223,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yeatts, Daniel S.","contributorId":22015,"corporation":false,"usgs":true,"family":"Yeatts","given":"Daniel","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":204224,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

During September 1995, three-dimensional water-velocity profiles were collected during the operation of fine-bubble and coarse-bubble aerators in a test tank at the U.S. Army Corps of Engineers Waterways Experiment Station. Three-dimensional water velocity, water-temperature, pH, dissolved oxygen concentration, and specific conductivity profiles were collected during operation of a coarse-bubble aerator in a reservoir in Schaumburg, Illinois, during summer 1996 and summer 1997, during strongly stratified and weakly stratified conditions. The effects of a submersible mixer alone and in combination with coarse-bubble aerators and a surface mixer alone also were investigated during summer 1997. The mixing patterns induced by the operation of aerators, submersible mixers, and surface mixers were described and compared with mixing patterns predicted by model simulations. Bubble-plume characteristics during tests in strongly stratified and weakly stratified conditions in the reservoir were documented and compared with characteristics simulated by different models. Lemckert and Imberger?s model simulates an entrainment rate similar to the rate measured during a test in the reservoir under strongly stratified conditions, whereas Schladow?s one-dimensional model appears to underestimate the total entrainment rate by about 50 percent. Schladow?s model was accurate during weak stratification but underestimated the radius of the plume during strong stratification. For 5 days during daylight hours, water temperature profiles were collected continuously during the operation of four aerators. Water temperatures in the reservoir were significantly affected by the operation of the aeration system. These changes were compared to simulations from a one-dimensional Dynamic Lake Model (DLM) simulation. DLM accurately simulated changes as a result of aeration, including daily changes. On the basis of temporal and spatial dissolved oxygen measurements, the volumetric quantity of oxygen in the reservoir was quantified before and after operation of a submersible mixer. A net loss of oxygen was calculated. This net loss may have resulted from a net warming of water throughout the reservoir or submerged supersaturated water releasing oxygen when the water came in contact with the atmosphere.

Contamination by bacteria of fecal origin in streams where contact recreation is a designated water use is a concern because of potential public-health risk from the presence of enteric pathogens. Fecal coliform concentrations are temporally and spatially variable in Wyoming streams-concentrations ranged from less than 1 to 45,000 colonies per 100 milliliters of water during 1990-99. Fecal coliform concentrations were less than the water-quality criterion of 400 colonies per 100 milliliters in 83 percent of the samples, indicating fecal coliform contamination is not a widespread problem in these Wyoming streams. However, 14 of the 18 monitoring sites had at least one sample in which the fecal coliform concentration exceeded 400 colonies per 100 milliliters at some time during the 10-year period. Fecal coliform concentrations generally are higher during April through September than during October through March. The higher concentrations coincide with the time period when the public-health risk is higher because summer months are when contact recreation use is more likely occurring. Fecal coliform concentrations were positively correlated with discharge and stream temperature and generally were negatively correlated with pH, specific conductance, and dissolved oxygen.","language":"ENGLISH","publisher":"U.S. Geological Survey, WRD,","doi":"10.3133/wri004198","usgsCitation":"Clark, M.L., and Norris, J.R., 2000, Occurrence of fecal coliform bacteria in selected streams in Wyoming, 1990-99: U.S. Geological Survey Water-Resources Investigations Report 2000-4198, 8 p., https://doi.org/10.3133/wri004198.","productDescription":"8 p.","costCenters":[],"links":[{"id":157346,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":1984,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri004198","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4af5e4b07f02db692269","contributors":{"authors":[{"text":"Clark, Melanie L. mlclark@usgs.gov","contributorId":1827,"corporation":false,"usgs":true,"family":"Clark","given":"Melanie","email":"mlclark@usgs.gov","middleInitial":"L.","affiliations":[{"id":5050,"text":"WY-MT Water Science Center","active":true,"usgs":true}],"preferred":true,"id":196671,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Norris, Jodi R.","contributorId":43746,"corporation":false,"usgs":true,"family":"Norris","given":"Jodi","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":196672,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
