Analysis of well boring samples and the results of electric resistivity surveys indicate that the average thickness of the unconsolidated alluvial deposits in the study area is about 100 to 110 feet. The alluvium is a mixture of sand and gravel, which generally has a porosity of 0.2 to 0.35. Short-duration pump tests in small-diameter piezometers indicate that the alluvial aquifer has a hydraulic conductivity of about 200 feet per day and a transmissivity of about 7,900 feet squared per day. \r\n\r\nAnalyses of water levels in piezometers, combined with stage measurements at a series of surveyed reference points along the Rio Grande de Manati channel, indicate that the water-table gradient in the alluvial aquifer is about 0.001, and that ground-water flow is generally from south to north, in the general direction of river flow. The water-table data indicate that the Rio Grande de Manati is the principal source of ground-water recharge to the alluvial aquifer in the study area. Because base flow for the Rio Grande de Manati is usually greater than 44 cubic feet per second, a continuous withdrawal rate of 0.5 to 1.0 cubic foot per second (225 to 450 gallons per minute) from a production well is possible. \r\n\r\nChemical analysis of a ground-water sample indicates that the alluvial aquifer water meets U.S. Environmental Protection Agency secondary standards for selected constituents. Bacteriological analysis of ground-water samples indicates that the ground water contains little or no fecal coliform or fecal streptococcus bacteria. Although long-term data from upstream of the study area indicate high levels of fecal coliform and fecal streptococcus prior to 1996, bacteriological analyses of Rio Grande de Manati water samples obtained during the present study indicate that fecal coliform and fecal streptococcus concentrations are within the standards for surface water intended for use (or with the potential for use) as a raw source of public water supply in Puerto Rico. \r\n\r\nIf a production well were constructed in the study area, it would be located close to the river channel (within 500 to 800 feet). Pumping from the porous and permeable alluvial aquifer close to the river channel could substantially enhance recharge from the Rio Grande de Manati channel to the aquifer. Enhanced recharge could shorten travel times for ground water in the aquifer, which might not allow sufficient time to attenuate bacteria and viruses. Travel times for bacteria moving from the river channel to a hypothetical production well were estimated using the numerical transport model MODFLOW/MT3DMS with an uncalibrated model of the alluvial aquifer. The model assumes a well pumping at 1 cubic foot per second. The transport of particles from the river to the well is most sensitive to the porosity of the aquifer and the pumping rate of the well. Sensitivity analysis indicates that a decrease in pumpage will increase the time of travel for particles to move from the river to the pumping well. The model indicates that the leading edge of a plume would reach the production well in about 40 days assuming a porosity of 0.20, 60 days assuming a porosity of 0.275, and about 70 days assuming a porosity of 0.35. If the well were moved 50 feet further from the river, the leading edge of the plume would reach the well in about 50 days assuming a porosity of 0.20 and about 70 days assuming a porosity of 0.275. These estimates are considered worse case estimates because no decay rate was included in the simulation, and because the hypothetical well was located in the center of the alluvial plain rather than further eastward, away from the river channel.","language":"ENGLISH","doi":"10.3133/wri024132","usgsCitation":"Torres-Gonzalez, S., Gómez-Gómez, F., and Warne, A.G., 2002, Ground-Water Resource Assessment in the Rio Grande de Manati Alluvial Plain, Rio Arriba Saliente Area, Puerto Rico (Online only): U.S. Geological Survey Water-Resources Investigations Report 2002-4132, 35 p., https://doi.org/10.3133/wri024132.","productDescription":"35 p.","onlineOnly":"Y","costCenters":[],"links":[{"id":5213,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pr.water.usgs.gov/public/online_pubs/wri02_4132/index.html","linkFileType":{"id":5,"text":"html"}},{"id":180714,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"edition":"Online only","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ab0e4b07f02db66d532","contributors":{"authors":[{"text":"Torres-Gonzalez, Sigfredo sttorres@usgs.gov","contributorId":3997,"corporation":false,"usgs":true,"family":"Torres-Gonzalez","given":"Sigfredo","email":"sttorres@usgs.gov","affiliations":[{"id":156,"text":"Caribbean Water Science Center","active":true,"usgs":true}],"preferred":true,"id":247573,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gómez-Gómez, Fernando","contributorId":31366,"corporation":false,"usgs":true,"family":"Gómez-Gómez","given":"Fernando","affiliations":[],"preferred":false,"id":247575,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Warne, Andrew G.","contributorId":9714,"corporation":false,"usgs":true,"family":"Warne","given":"Andrew","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":247574,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The population of this arid region continues to grow, and the number of visitors to the many national and state parks and monuments in the region has increased annually. The sustainability, protection, and maintenance of springs and seeps and associated riparian habitat on the Coconino Plateau are major issues that have broad public and governmental support.</p>\n<br/>\n<p>Regional stakeholders agree that an improved understanding of the regional hydrogeologic system is needed to address the concerns of water supply and ground-water sustainability. The base of information required to adequately describe the hydrogeology of the Coconino Plateau currently does not exist. Hydrogeologic data is most abundant for large population centers like Flagstaff and Sedona, but is sparse for less populated areas like Williams, Tusayan, Valle, and Cameron. There are still large parts of the Coconino Plateau for which there is no basic geologic or hydrologic information available. In order to develop a hydrogeologic framework for the Coconino Plateau, a comprehensive effort is needs to compile existent data and collect additional data to fill in data gaps and reinforce limited information.</p>\n<br/>\n<p>In 1999, the U.S. Geological Survey (USGS) began an assessment of the hydrogeology of the Coconino Plateau in cooperation with the Arizona Department of Water Resources (ADWR) as part of the Rural Watershed Initiative, a program established by the State of Arizona and managed by the ADWR.

Concentrations of selected trace elements and organic compounds were compared on the basis of sediment-quality criteria, land use, and grain size; concentrations of selected trace elements also were compared with concentrations from previous studies. Concentrations of seven selected trace elements and 21 organic compounds were evaluated with sediment-quality criteria established by the Canadian Council of Ministers of the Environment. Concentrations of selected trace elements and organic compounds were highest at sites draining urban and agricultural areas and may result from cumulative effects of relatively high percentages of fine-grained material, iron, and organic material. Concentrations exceeding sediment-quality criteria for the protection of aquatic life occurred most frequently at Bayou Grosse Tete at Rosedale and Bayou Lafourche below weir at Thibodaux. Exceedance of Interim Sediment Quality Guidelines occurred most frequently for arsenic and chromium. Trace-element concentrations in fine-grained samples were compared with concentrations in bulk samples and were determined to be significantly different, and concentrations were generally higher in finegrained sediment. Shapiro-Wilk, paired t-test, and Wilcoxon rank sum statistical procedures, with an alpha of 0.05, were used to compare concentrations of 21 trace elements, total organic carbon, and total carbon in finegrained and bulk sediment samples for 19 sites. Significant differences were determined between fine-grained and bulk sediment samples for aluminum, barium, beryllium, chromium, copper, iron, lithium, nickel, phosphorus, selenium, titanium, and zinc concentrations. Of 133 paired concentrations, 69 percent were greater in fine-grained samples, and 23 percent were greater in bulk samples.

Mean recharge estimated as a percentage (27 percent) of precipitation ranged from 7.7 to 8.3 in./yr across the study area. The median recharge estimated from automated analyses of streamflow-recession displacements for seven basins ranged from 1.2 to 12.2 in./yr. Median recharge estimated from graphical analyses of groundwater level fluctuations for 11 wells ranged from 4.5 to 13.6 in./yr. Recharge estimated by age dating of shallow ground water at a nested well site was 8.8 in./yr. Minimal ground-water recharge estimated by statistical analyses of watershed characteristics (geologic data and streamflow records) ranged from less than 0.1 to 5.6 in./yr.</p>\n<p>Leakage, considered recharge to confined aquifers, in the seven-county Twin Cities metropolitan area was estimated by two methods. Leakage estimated by analyses of ground-water level fluctuations for 11 wells ranged from 3.2x10<sup>-3</sup> to 1.1x10<sup>-2</sup> in./yr. Leakage estimated by analyses of vertical-hydraulic gradients based on application of the Darcy flow equation for seven nested well sites ranged from 4.6x10<sup>-5</sup> to 1.1x10<sup>-1</sup> in./yr.</p>\n<p>Recharge estimates, which generally varied within 10 in./yr for each of the methods, generally were largest based on the precipitation, ground-water level fluctuation, and age dating of shallow ground water methods, slightly smaller based on the streamflow-recession displacement method, and smallest based on the watershed characteristics method. Leakage, which was less than 1 in./yr, varied within 1 order of magnitude based on the ground-water level fluctuation method and as much as 4 orders of magnitude based on analyses of vertical-hydraulic gradients.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Mounds View, MN","doi":"10.3133/wri20024092","collaboration":"Prepared in cooperation

The Bureau of Reclamation (BOR) manages the river, releasing water stored in Lakes Mead, Mohave, and Havasu, and in other smaller reservoirs as needed so that it can be used by diverters. To help guide river management, streamflow and reservoir content are monitored at strategically located gaging stations along the lower Colorado River, its tributaries, and its diversions. The data obtained from these gaging stations, however, contain uncertainty and are only estimates of the ‘‘true’’ streamflow and reservoir content. As part of a cooperative project with the BOR, the U.S. Geological Survey (USGS) estimated the standard error of the annual discharge for calendar years 1995–99 at 14 streamflow-gaging stations and the standard error of the change in reservoir content at 2 reservoir-content gaging stations (table 1 and fig.1; Anning, 2002).

Geophysical logs include gamma, normal resistivity, fluid-column temperature and resistivity, caliper, televiewer, and heat-pulse flowmeter. These logs were run in two boreholes penetrating only the Fountain Formation of Pennsylvanian and Permian age (logged to depths of about 65 and 570 feet) and in four boreholes (logged to depths of about 342 to 742 feet) penetrating mostly the Fountain Formation and terminating in Precambrian crystalline rock, which underlies the Fountain Formation. Data from the logs were used to identify fractures and bedding planes and to locate the contact between the two formations. The logs indicated few fractures in the boreholes and gave no indication of higher transmissivity in the contact zone between the two formations. Transmissivities for all fractures in each borehole were estimated to be less than 2 feet squared per day.","language":"ENGLISH","doi":"10.3133/ofr02364","usgsCitation":"Paillet, F.L., Hodges, R.E., and Corland, B.S., 2002, Analysis of geophysical logs from six boreholes at Lariat Gulch, former U.S. Air Force site PJKS, Jefferson County, Colorado: U.S. Geological Survey Open-File Report 2002-364, 39 p., 10 figs., https://doi.org/10.3133/ofr02364.","productDescription":"39 p., 10 figs.","costCenters":[],"links":[{"id":178432,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":4165,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/ofr02364","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acfe4b07f02db6804f5","contributors":{"authors":[{"text":"Paillet, Frederick L.","contributorId":38191,"corporation":false,"usgs":true,"family":"Paillet","given":"Frederick","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":242085,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hodges, Richard E.","contributorId":47452,"corporation":false,"usgs":true,"family":"Hodges","given":"Richard","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":242086,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Corland, Barbara S.","contributorId":83598,"corporation":false,"usgs":true,"family":"Corland","given":"Barbara","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":242087,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Most of the water bodies on the list were assessed using water-column measures such as concentrations of dissolved oxygen (DO) and total metals as surrogates for aquatic biological data. Many water bodies were listed because of low concentrations of DO or potentially toxic dissolved metals such as lead; ambient toxicity to nonresident (laboratory) aquatic organisms also could have been a reason for listing. The Texas Natural Resource Conservation Commission (TNRCC) has emphasized the use of aquatic biological data to determine if a water body should be included or removed from the 303(d) list. </p><p>The standards used to determine whether a water body should be on the State 303(d) list generally are statewide standards that have not been adjusted for regional or watershed-scale differences that reflect variability across Texas.

Water-quality and benthic macroinvertebrate community samples were collected and habitat was measured once at 25 ambient monitoring sites during periods of seasonal low flow. Water-quality storm-runoff samples were collected during 11 storm events at two sites (one draining a cotton field and one draining a forested area). Water-quality samples were collected at one site during the draining of a catfish pond.\r\n\r\nWater-quality samples from the 25 ambient sites indicate that streams in the Boeuf River Basin typically are turbid and nutrient enriched in late fall during periods of relatively low flow. Most suspended solids concentrations ranged from about 50 to 200 milligrams per liter (mg/L), most total nitrogen concentrations ranged from about 1.1 to 1.8 mg/L, and most total phosphorus concentrations ranged from about 0.25 to 0.40\r\nmg/L.\r\n\r\nSuspended solids, total nitrogen, total ammonia plus organic nitrogen, total phosphorus, and dissolved orthophosphorus concentrations from samples collected during storm events were typically higher at the cotton field site than at the forested site. Estimated annual yields of suspended solids, nitrogen, and phosphorus were substantially higher from the cotton field than from the forested area. Dissolved chloride concentrations typically were higher at the forested site than from the cotton field site. Typically, the suspended solids and nutrient concentrations from the 25 ambient sites were lower than concentrations in runoff from the cotton field but higher than concentrations in runoff from the forest area. Concentrations of sulfate, chloride, suspended solids, and some nutrients in samples from the catfish pond generally were greater than concentrations in samples from other sites. Total phosphorus, orthophosphorus, and fecal coliform bacteria concentrations from the catfish pond generally were lower than concentrations in samples from other sites.\r\n\r\nBiological condition scores calculated using macroinvertebrate samples and U.S. Environmental Protection Agency Rapid Bioassessment Protocol II indicated that most of the 25 ambient sites would be in the 'moderately impaired' category. However, substantial uncertainty exists in this rating because bioassessment data were compared with data from a reference site outside of the Boeuf River Basin sampled using different methods. Several metrics indicated that communities at most of the ambient sites are composed of more tolerant macroinvertebrates than the community at the reference site.\r\n\r\nHabitat assessments (using Rapid Bioassessment Protocol II) indicated the reference site outside the Boeuf River Basin had better habitat than the ambient sites. Physical habitat scores for the 25 ambient sites indicated that most ambient sites had poor bottom substrate cover, embeddedness values, and flow and had poor to fair habitat related to most other factors. Most habitat factors at the reference site were considered good to excellent.\r\n\r\nPart of the variation in biological condition scores was explained by physical habitat scores and concentrations of suspended solids and dissolved oxygen. However, a considerable amount of variability in biological condition scores is not explained by these factors.","language":"ENGLISH","doi":"10.3133/wri024187","usgsCitation":"Barks, C.S., Petersen, J., and Usrey, F.D., 2002, Water-quality, biological, and habitat assessment of the Boeuf River Basin, southeastern Arkansas, 1994-96: U.S. Geological Survey Water-Resources Investigations Report 2002-4187, iv, 36 p. : ill., maps ; 28 cm., https://doi.org/10.3133/wri024187.","productDescription":"iv, 36 p. : ill., maps ; 28 cm.","costCenters":[],"links":[{"id":3804,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://ar.water.usgs.gov/LOCAL_REPORTS/WRIR_02-4187/WRIR_02-4187.html","linkFileType":{"id":5,"text":"html"}},{"id":134868,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e47a0e4b07f02db49468a","contributors":{"authors":[{"text":"Barks, C.

Availability of water is an important issue in this area because of continued industrial and municipal use, a growing population, and precipitation of about 6 to 14 inches per year.</p>\n<br>\n<p>The monitoring program in Black Mesa has been operating since 1971 and is designed to determine the long-term effects of ground-water withdrawals from the N aquifer for industrial and municipal uses. The monitoring program includes measurements of (1) ground-water pumping, (2) ground-water levels, (3) spring discharge, (4) surface-water discharge, and (5) ground-water chemistry.</p>\n<br>\n<p>In 2000, total ground-water withdrawals were 7,740 acre-feet, industrial use was 4,490 acre-feet, and municipal use was 3,250 acre-feet. From 1999 to 2000, total withdrawals increased by 9 percent, industrial use increased by 7 percent, and municipal use increased by 12 percent.</p>\n<br>\n<p>From 1999 to 2001, water levels declined in 10 of 15 wells in the unconfined part of the aquifer, and the median change was -0.4 foot. Water levels declined in 8 of 16 wells in the confined part of the aquifer, and the median change was -0.2 foot.</p> \n<br>\n<p>From the prestress period (prior to 1965) to 2001, the median water-level change for 33 wells was -17.2 feet. Median water-level changes were -1.2 feet for 15 wells in the unconfined part of the aquifer and -31.0 feet for 18 wells in the confined part.</p> \n<br>\n<p>Discharges were measured once in 1999 and once in 2001 at four springs. Discharges decreased by 5 percent and 33 percent at two springs and increased by 3 percent and 81 percent at two springs. For about the past 10 years, discharges did not significantly change in Burro Spring, the unnamed spring near Dennehotso, and Moenkopi School Spring. The record of discharge from a consistent measuring point for Pasture Canyon Spring is too short for statistical analysis of trends.</p>\n<br>\n<p>Continuous records of surface-water discharge have been collected from July 1976 to 2000 at Moenkopi Wash, July 1996 to 2000 at Laguna Creek, June 1993 to 2000 at Dinnebito Wash, and April 1994 to 2000 at Polacca Wash. Median flows for November, December, January, and February of each water year were used as an index of ground-water discharge to those streams. There is no significant trend in the median winter flows for Moenkopi Wash from 1977 to 2000. The records for the other three streams are too short for a statistical analysis of trends. The median winter flows for Dinnebito Wash and Polacca Wash, however, appear to have decreased during the last 6 years. There is no apparent trend in the median winter flows for Laguna Creek since 1997.<p> \n<br>\n<p>In 2001, water samples were collected from 12 wells and 4 springs and analyzed for selected chemical constituents. Dissolved-solids concentrations ranged from 102 to 628 milligrams per liter. Water samples from 9 of the wells and from the 4 springs had less than 350 milligrams per liter of dissolved solids. Water-chemistry data with sufficient years of record for a statistical analysis of trends over time are available from 7 wells and 4 springs. From about the mid-1980s or early 1990s to 2001 there are no significant trends in the concentrations of dissolved solids, chloride, and sulfate in water samples from 6 of the 7 wells. The concentration of one tested constituent (dissolved solids) in samples from Rocky Ridge PM3 significantly increased from 1990 to 2001. From the late 1980s to 2001, there are no significant trends in the concentrations of dissolved solids, chloride, and sulfate in water samples from Burro Spring, the unnamed spring near Dennehotso, and Pasture Canyon Spring. From 1987 to 2001, concentrations of chloride and sulfate significantly increased in water samples from Moenkopi School Spring and concentrations of dissolved solids did not significantly change.</p> \n<br>\n<p>The performance and sensitivity of the 1988\nUSGS numerical model of the N aquifer were\nanalyzed. The overall performance of the model in\nsteady-state conditions is reasonable for residuals\nof heads (difference between observed and\nsimulated steady-state heads); 80 percent of the\nabsolute values of residuals are less than 38 feet.\nSimulated flows are about 40 percent different\nthan estimated flows at two of three discharge\nareas; however, this comparison is only a rough\napproximation of performance because the\naccuracy of the estimated steady-state flows is\nuncertain.</p>\n<br>\n<p>The overall performance of the model for\ntransient conditions is fair for residuals of changes\nin head (difference between observed and\nsimulated changes in head from steady state to\n1999); 80 percent of the absolute values of\nresiduals are less than 31 feet. The model is biased\nin two areas. In the Tuba City area, simulated\nchanges in head are more negative than observed\nchanges in head; all six residuals are positive, and\nthree residuals are between 75 and 155 feet. In the\nconfined area of the aquifer, observed changes in\nhead are more negative than simulated changes in\nhead; 12 of the 17 residuals are negative, and\n8 residuals are between -57 and -20 feet.</p>\n<br>\n<p>Analysis of model sensitivity indicates that\nrecharge, transmissivity, and storage coefficient\nare the most important parameters for estimating\nheads, changes in heads, and flows. A strong\ncorrelation between recharge and transmissivity\nand a lack of independent and reliable estimates of\nrecharge, transmissivity, and discharge create a\nuniqueness problem in model calibration. Several\nmodels could be constructed and calibrated with\ndifferent values of recharge or transmissivity and\nstill have similar fits to the observed data.\nInformation from recent data and studies and more\nadvanced modeling techniques could be used to\ndevelop a more representative and less uncertain\nmodel. Future data collection and studies should\nfocus on obtaining a better definition of recharge,\ndischarge, transmissivity, and storage coefficient.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Tucson, AZ","doi":"10.3133/wri024211","collaboration":"Prepared in cooperation with the Arizona Department of Water Resources and Bureau of Indian Affairs","usgsCitation":"Thomas, B.E., 2002, Ground-water, surface-water, and water-chemistry data, Black Mesa Area, northeastern Arizona — 2000–2001, and performance and sensitivity of the 1988 USGS numerical model of the N aquifer: U.S. Geological Survey Water-Resources Investigations Report 2002-4211, vii, 76 p., https://doi.org/10.3133/wri024211.","productDescription":"vii, 76 p.","numberOfPages":"84","costCenters":[],"links":[{"id":288425,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":394547,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_52780.htm"},{"id":288424,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/2002/4211/report.pdf"}],"country":"United States","state":"Arizona","otherGeospatial":"Black Mesa area","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -111.4167,\n              35.5833\n            ],\n            [\n              -109.5833,\n              35.5833\n            ],\n            [\n              -109.5833,\n              36.8833\n            ],\n            [\n              -111.4167,\n              36.8833\n            ],\n            [\n              -111.4167,\n              35.5833\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a80e4b07f02db649ba5","contributors":{"authors":[{"text":"Thomas, Blakemore E.","contributorId":93871,"corporation":false,"usgs":true,"family":"Thomas","given":"Blakemore","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":222672,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Used together these elements form an effective, practical canister desorption method.","language":"ENGLISH","doi":"10.3133/ofr02496","usgsCitation":"Barker, C., Dallegge, T.A., and Clark, A.C., 2002, USGS Coal Desorption Equipment and a Spreadsheet for Analysis of Lost and Total Gas from Canister Desorption Measurements (Version 1.0): U.S. Geological Survey Open-File Report 2002-496, 13 p., https://doi.org/10.3133/ofr02496.","productDescription":"13 p.","costCenters":[],"links":[{"id":178625,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":4229,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2002/ofr-02-496/","linkFileType":{"id":5,"text":"html"}}],"edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a29e4b07f02db61197f","contributors":{"authors":[{"text":"Barker, Charles E.","contributorId":93070,"corporation":false,"usgs":true,"family":"Barker","given":"Charles E.","affiliations":[],"preferred":false,"id":242191,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dallegge, Todd A.","contributorId":38614,"corporation":false,"usgs":true,"family":"Dallegge","given":"Todd","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":242190,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Clark, Arthur C. aclark@usgs.gov","contributorId":2320,"corporation":false,"usgs":true,"family":"Clark","given":"Arthur","email":"aclark@usgs.gov","middleInitial":"C.","affiliations":[],"preferred":true,"id":242189,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

This workshop was similar in nature to the previous five meetings, held in Lawrence, Kansas (Soller, 1997), in Champaign, Illinois (Soller, 1998a), in Madison, Wisconsin (Soller, 1999), in Lexington, Kentucky (Soller, 2000), and in Tuscaloosa, Alabama (Soller, 2001). This year's meeting was hosted by the Utah Geological Survey, from May 19 to 22, 2002, on the University of Utah campus in Salt Lake City. As in the previous meetings, the objective was to foster informal discussion and exchange of technical information. When an attendee adopts or modifies a newly learned technique on the basis of discussions at the workshop, the workshop clearly has met that objective. Evidence of learning and cooperation among participating agencies continued to be a highlight of the DMT workshops (see example in Soller, 1998b, and various papers in this volume).</p><p>All the DMT workshops have been coordinated by the Association of American State Geologists (AASG) and the U.S. Geological Survey (USGS) Data Capture Working Group, which was formed in August 1996 to support the AASG and the USGS in their effort to build a National Geologic Map Database (see Soller and Berg, this volume, and<span>&nbsp;</span><a href=\"http://ncgmp.usgs.gov/ngmdbproject/standards/datacapt/\" target=\"_BLANK\" data-mce-href=\"http://ncgmp.usgs.gov/ngmdbproject/standards/datacapt/\">http://ncgmp.usgs.gov/ngmdbproject/standards/datacapt/</a>). The Working Group was formed because increased production efficiencies, standardization, and quality of digital map products were needed for the database--and the State and Federal geological surveys--to provide more high-quality digital maps to the public.</p><p>At the 2002 meeting, oral and poster presentations and special discussion sessions emphasized (1) methods for creating and publishing map products (here, \"publishing\" includes Web-based release); (2) techniques for scanning already published maps and managing and delivering them on the Web; (3) continued development of the National Geologic Map Database; and (4) progress toward building a standard geologic map data model.

The Memphis study area consists of 76 square miles of residential-commercial areas ranging in age from 5 to 25 years.\r\n\r\nAtrazine was the only compound in this study detected at a concentration that exceeded a U.S. Environmental Protection Agency primary drinking-water standard. Manganese, iron, and dissolved solids concentrations in water from some wells exceeded secondary standards. At least one pesticide was detected in water from 24 of 32 wells. The most frequently detected pesticides in water from the monitor wells were atrazine, simazine, and metolachlor. At least one VOC was detected in water from 31 of 32 wells. The most frequently detected VOCs in water from the wells were carbon disulfide, chloroform, m- and pxylenes, tetrachloroethene, and toluene.\r\n\r\nWater from 17 wells was a sodium bicarbonate type water; water from 12 wells was a calciummagnesium bicarbonate type water; water from 2 wells was a sodium chloride type water; water from 1 well was a sodium mixed anion type water. Based on both tritium and chlorofluorocarbon data, the average age of water from the monitor wells in the Memphis study area was estimated to range from 10 to more than 43 years old.

We have updated the eastern portion of our previous active fault map of Oregon (Pezzopane, Nakata, and Weldon, 1992) as a contribution to the larger USGS effort to produce digital maps of active faults in the Pacific Northwest region. The 1992 fault map has seen wide distribution and has been reproduced in essentially all subsequent compilations of active faults of Oregon. The new map provides a substantial update of known active or suspected active faults east of the Cascades. Improvements in the new map include (1) many newly recognized active faults, (2) a linked ArcInfo map and reference database, (3) more precise locations for previously recognized faults on shaded relief quadrangles generated from USGS 30-m digital elevations models (DEM), (4) more uniform coverage resulting in more consistent grouping of the ages of active faults, and (5) a new category of 'possibly' active faults that share characteristics with known active faults, but have not been studied adequately to assess their activity. The distribution of active faults has not changed substantially from the original Pezzopane, Nakata and Weldon map. Most faults occur in the south-central Basin and Range tectonic province that is located in the backarc portion of the Cascadia subduction margin. These faults occur in zones consisting of numerous short faults with similar rates, ages, and styles of movement. Many active faults strongly correlate with the most active volcanic centers of Oregon, including Newberry Craters and Crater Lake.","language":"ENGLISH","doi":"10.3133/ofr02301","isbn":"060799679X","usgsCitation":"Weldon, R.J., Fletcher, D., Weldon, E., Scharer, K., and McCrory, P., 2002, An update of Quaternary faults of central and eastern Oregon (Version 1.0): U.S. Geological Survey Open-File Report 2002-301, 1 CD-ROM ; 4 3/4 in., https://doi.org/10.3133/ofr02301.","productDescription":"1 CD-ROM ; 4 3/4 in.","costCenters":[],"links":[{"id":175793,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":10484,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2002/of02-301/","linkFileType":{"id":5,"text":"html"}}],"edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db683875","contributors":{"authors":[{"text":"Weldon, Ray J.

For most of the century, event data were published only in Russian and were generally unavailable to the Western scientific community. Yet for many regions of this vast territory, earthquakes with magnitudes less than 2 were routinely located and characterized, especially since the early 1960s. A great volume of data on the seismicity of the Eurasian land mass is therefore available, although to date only in scattered publications and for incomplete periods of time.</p><p>To address this problem, we have undertaken a comprehensive compilation, documentation and evaluation of catalogs of seismicity of the former Soviet Union. These include four principal, Soviet-published catalog sources, supplemented by other publications. We view this as the first step in compiling a complete catalog of all known seismic events in this large and important region. Completion of this work will require digitizing the remaining catalogs of the various regional seismological institutes. </p><p>To make these data more useful for regional seismic investigations, as well as to be consistent with their provenance, we have prepared composite regional catalogs, dividing the territory of the former Soviet Union into 24 regions. For each of these regions, all the data available from the basic catalog sources (see below) have been combined and evaluated.

Land use prior to the construction of the LMFOs was assessed to evaluate the types of agricultural land use within a 500-meter radius of the sampled wells.\r\n\r\nChemical and microbiological techniques were used to determine the possible sources of nitrate in water sampled from 10 wastewater lagoons and 79 wells. Samples were analyzed for dissolved major ions, dissolved trace elements, dissolved nutrients, nitrogen isotope ratios of nitrate and ammonia, wastewater organic compounds, and fecal coliform bacteria. Bacteria ribotyping analysis was done on selected samples to identify possible specific animal sources.\r\n\r\nA decision process was developed to identify the possible sources of nitrate. First, nitrogen isotope ratios were used to define sources as animal, mixed animal and fertilizer, or fertilizer. Second, wastewater organic compound detections, nitrogen-isotope ratios, fecal coliform bacteria detections, and ribotyping were used to refine the identification of possible sources as LFMO waste, fertilizer, or unidentified animal or mixtures of these sources. Additional evidence provided by ribotyping and wastewater organic compound data can, in some cases, specifically indicate the animal source. Detections of three or more wastewater organic compounds that are indicators of animal sources and detections of fecal coliform bacteria provided additional evidence of an animal source.\r\n\r\nLMFO waste was designated as a possible source of nitrate in water from 10 wells. The source of waste in water from five of those wells was determined through ribotyping, and the source of waste in water from the remaining five wells was determined by detections of three or more animal-waste compounds in the well samples. LMFO waste in the water from wells with unidentified animal source of nitrate does not indicate that LMFO waste was not the source, but indicated that multiple animal sources, including LMFO waste, may be the source of the nitrate.","language":"ENGLISH","doi":"10.3133/wri024257","usgsCitation":"Becker, M.F., Peter, K.D., and Masoner, J., 2002, Possible sources of nitrate in ground water at swine licensed-managed feeding operations in Oklahoma, 2001: U.S. Geological Survey Water-Resources Investigations Report 2002-4257, 76 p. : ill.
