The study focussed on monitoring for organic chemical contamination and the effects of construction and operation of State Route 125 on water quality. Three environmental compartments (air, water, and bed sediments) are being sampled regularly for chemical contaminants, including volatile organic compounds, polynuclear aromatic hydrocarbons, polychlorinated biphenyls, pesticides, and major and trace elements. The study is divided into two phases. Phase I sampling is designed to establish baseline conditions for target compounds in terms of detection frequency and concentration in air, water, and bed sediments. Phase II sampling will continue at the established monitoring sites during and after construction of State Route 125 to assess chemical impact on water quality in the reservoir resulting from land-use changes and development in the watershed. This report describes the study design, the sampling and analytical methods, and presents the data results for the first year of the study, September 1998 to September 1999.","language":"ENGLISH","doi":"10.3133/ofr02186","usgsCitation":"Majewski, M.S., Sidhu, J.S., and Mendez, G.O., 2002, Water quality monitoring of Sweetwater and Loveland reservoirs--Phase one results 1998-1999: U.S. Geological Survey Open-File Report 2002-186, 133 p., 14 tables, https://doi.org/10.3133/ofr02186.","productDescription":"133 p., 14 tables","costCenters":[],"links":[{"id":4128,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/ofr02186/ ","linkFileType":{"id":5,"text":"html"}},{"id":170033,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a48e4b07f02db6234a5","contributors":{"authors":[{"text":"Majewski, Michael S. majewski@usgs.gov","contributorId":440,"corporation":false,"usgs":true,"family":"Majewski","given":"Michael","email":"majewski@usgs.gov","middleInitial":"S.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":241985,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Sidhu, Jagdeep S.","contributorId":27526,"corporation":false,"usgs":true,"family":"Sidhu","given":"Jagdeep","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":241987,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Mendez, Gregory O. 0000-0002-9955-3726 gomendez@usgs.gov","orcid":"https://orcid.org/0000-0002-9955-3726","contributorId":1489,"corporation":false,"usgs":true,"family":"Mendez","given":"Gregory","email":"gomendez@usgs.gov","middleInitial":"O.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":false,"id":241986,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Each spreadsheet incorporates analytical solution(s) of the partial differential equation for ground-water flow to a well for a specific type of condition or aquifer. The derivations of the analytical solutions were previously published. Thus, this report abbreviates the theoretical discussion, but includes practical information about each method and the important assumptions for the applications of each method. These spreadsheets were written in Microsoft Excel 9.0 (use of trade names does not constitute endorsement by the USGS). Storage properties should not be estimated with many of the spreadsheets because most are for analyzing single-well tests. Estimation of storage properties from single-well tests is generally discouraged because single-well tests are affected by wellbore storage and by well construction. These non-ideal effects frequently cause estimates of storage to be erroneous by orders of magnitude. Additionally, single-well tests are not sensitive to aquifer-storage properties. Single-well tests include all slug tests (Bouwer and Rice Method, Cooper, Bredehoeft, Papadopulos Method, and van der Kamp Method), the Cooper-Jacob straight-line Method, Theis recovery-data analysis, Jacob-Lohman method for flowing wells in a confined aquifer, and the step-drawdown test. Multi-well test spreadsheets included in this report are; Hantush-Jacob Leaky Aquifer Method and Distance-Drawdown Methods. The distance-drawdown method is an equilibrium or steady-state method, thus storage cannot be estimated.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr02197","usgsCitation":"Halford, K.J., and Kuniansky, E.L., 2002, Documentation of spreadsheets for the analysis of aquifer-test and slug-test data (Version 1.2): U.S. Geological Survey Open-File Report 2002-197, 51 p., https://doi.org/10.3133/ofr02197.","productDescription":"51 p.","costCenters":[],"links":[{"id":170113,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":4130,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2002/ofr02197/","linkFileType":{"id":5,"text":"html"}}],"edition":"Version 1.2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a61e4b07f02db636171","contributors":{"authors":[{"text":"Halford, Keith J. 0000-0002-7322-1846 khalford@usgs.gov","orcid":"https://orcid.org/0000-0002-7322-1846","contributorId":1374,"corporation":false,"usgs":true,"family":"Halford","given":"Keith","email":"khalford@usgs.gov","middleInitial":"J.","affiliations":[{"id":465,"text":"Nevada Water Science Center","active":true,"usgs":true}],"preferred":true,"id":241995,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kuniansky, Eve L. 0000-0002-5581-0225 elkunian@usgs.gov","orcid":"https://orcid.org/0000-0002-5581-0225","contributorId":932,"corporation":false,"usgs":true,"family":"Kuniansky","given":"Eve","email":"elkunian@usgs.gov","middleInitial":"L.","affiliations":[{"id":509,"text":"Office of the Associate Director for Water","active":true,"usgs":true},{"id":5064,"text":"Southeast Regional Director's Office","active":true,"usgs":true}],"preferred":true,"id":241994,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Because the regression equation discharge agrees closely with the high end of the range of discharges estimated from the gaging-station records, it was used for the hydraulic modeling to ensure that the resulting 50-year-flood water-surface elevations would not be underestimated.\r\n\r\nThe 50-year-flood discharge for Rio Majada at Comayagua (230 cubic meters per second) was estimated using the regression equation because there are no long-term gaging-stations on this river from which to estimate the discharge.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr02251","usgsCitation":"Kresch, D.L., Mastin, M.C., and Olsen, T.D., 2002, Fifty-year flood-inundation maps for Comayagua, Hondura: U.S. Geological Survey Open-File Report 2002-251, 11 p., https://doi.org/10.3133/ofr02251.","productDescription":"11 p.","costCenters":[],"links":[{"id":4141,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2002/ofr02251/index.html","linkFileType":{"id":5,"text":"html"}},{"id":170182,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"Hondura","city":"Comayagua","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -89.43251127996213,\n              16.43006388749069\n            ],\n            [\n              -89.43251127996213,\n              12.876909617568344\n            ],\n            [\n              -82.7967072779427,\n              12.876909617568344\n            ],\n            [\n              -82.7967072779427,\n              16.43006388749069\n            ],\n            [\n              -89.43251127996213,\n              16.43006388749069\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49fbe4b07f02db5f489a","contributors":{"authors":[{"text":"Kresch, David L.","contributorId":46084,"corporation":false,"usgs":true,"family":"Kresch","given":"David","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":242020,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Mastin, Mark C. 0000-0003-4018-7861 mcmastin@usgs.gov","orcid":"https://orcid.org/0000-0003-4018-7861","contributorId":1652,"corporation":false,"usgs":true,"family":"Mastin","given":"Mark","email":"mcmastin@usgs.gov","middleInitial":"C.","affiliations":[{"id":622,"text":"Washington Water Science Center","active":true,"usgs":true}],"preferred":true,"id":242018,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Olsen, T.

This report, which is one in a series of 15, presents maps of areas in the coastal municipality of Santa Rosa de Aguan that are prone to oceanic storm-surge flooding and wave action. The 50-year flood on the Rio Aguan (4,270 cubic meters per second), would inundate most of the area surveyed for this municipality and beyond. Therefore a detailed numerical hydraulic model was not developed for this municipality as it was for the others. The 50-year storm surge would likely produce higher water levels than the 50-year flood on the river during normal astronomical tides.

Data were collected in support of ongoing research studies to improve the understanding of hydrologic and contaminant-transport processes in arid environments. \r\n\r\nMicrometeorological data include precipitation, air temperature, solar radiation, net radiation, relative humidity, ambient vapor pressure, wind speed and direction, barometric pressure, soil temperature, and soil-heat flux. All micrometeorological data were collected using a 10-second sampling interval by data loggers that output daily mean, maximum, and minimum values, and hourly mean values. For precipitation, data output consisted of daily, hourly, and 5-minute totals. Soil-moisture data included periodic measurements of soil-water content at nine neutron-probe access tubes with measurable depths ranging from 5.25 to 29.75 meters.\r\n\r\nThe computer data files included in this report contain the complete micrometeorological and soil-moisture data sets. The computer data consists of seven files with about 14 megabytes of information. The seven files are in tabular format: (1) one file lists daily mean, maximum, and minimum micrometeorological data and daily total precipitation; (2) three files list hourly mean micrometeorological data and hourly precipitation for each year (1998-2000); (3) one file lists 5-minute precipitation data; (4) one file lists mean soil-water content by date and depth at four experimental sites; and (5) one file lists soil-water content by date and depth for each neutron-probe access tube.\r\n\r\nThis report highlights selected data contained in the computer data files using figures, tables, and brief discussions.

Thirty-seven analyses are reported for 1999, 18 for June of 2000, and 12 for\r\nSeptember of 2000. These water samples were collected and analyzed as part of research\r\ninvestigations in YNP on microbially mediated sulfur oxidation in stream water, arsenic and sulfur\r\nredox speciation in hot springs, and chemical changes in overflow drainages that affect major ions,\r\nredox species, and trace elements. Most samples were collected from sources in the Norris Geyser\r\nBasin. Two ambient-temperature acidic stream systems, Alluvium and Columbine Creeks and their\r\ntributaries in Brimstone Basin, were studied in detail. Analyses were performed at or near the\r\nsampling site, in an on-site mobile laboratory truck, or later in a USGS laboratory, depending on\r\nstability of the constituent and whether or not it could be preserved effectively.\r\nWater temperature, specific conductance, pH, Eh, dissolved oxygen (D.O.), and dissolved\r\nH2S were determined on-site at the time of sampling. Alkalinity, acidity, and F were determined\r\nwithin a few days of sample collection by titration with acid, titration with base, and ion-selective\r\nelectrode or ion chromatography (IC), respectively. Concentrations of S2O3 and SxO6 were\r\ndetermined as soon as possible (minutes to hours later) by IC. Concentrations of Br, Cl, NH4, NO2,\r\nNO3, SO4, Fe(II), and Fe(total) were determined within a few days of sample collection. Densities\r\nwere determined later in the USGS laboratory.\r\nConcentrations of Li and K were determined by flame atomic absorption spectrometry.\r\nConcentrations of Al, As(total), B, Ba, Be, Ca, Cd, Co, Cr, Cu, Fe(total), K, Li, Mg, Mn, Na, Ni, Pb,\r\nSe, Si, Sr, V, and Zn were determined by inductively-coupled plasma-optical emission spectrometry.\r\nTrace concentrations of Cd, Cr, Cu, Pb, and Sb were determined by Zeeman-corrected graphitefurnace\r\natomic-absorption spectrometry. Trace concentrations of As(total) and As(III) were\r\ndetermined by hydride generation atomic-absorption spectrometry using a flow-injection analysis\r\nsystem. Concentrations of Cl, NO3, Br, and SO4 were determined by IC. Concentrations of Fe(II)\r\nand Fe(total) were determined by the ferrozine colorimetric method. Concentrations of NO2 were\r\ndetermined by colorimetry using matrix-matched standards. Concentrations of NH4 were determined\r\nby IC, with reanalysis by colorimetry where separation of Na and NH4 peaks was poor.

Current research indicates many of these compounds can bioaccumulate and may adversely affect aquatic organisms by disrupting physiological processes, impairing reproductive functions, increasing cancer rates, contributing to the development of antibiotic-resistant strains of bacteria, and acting in undesirable ways when mixed with other substances. These compounds may be present in effluent because a high percentage of prescription and non-prescription drugs used for human-health purposes are excreted from the body as a mixture of parent compounds and degraded metabolite compounds; also, they can be released to the environment when unused products are discarded by way of toilets, sinks, and trash in landfills. \r\n\r\nThirteen of 33 targeted compounds were detected in at least one water sample collected between October 2000 and August 2001. All concentrations were less than or equal to 0.20 micrograms per liter. The most frequently detected compounds in samples from Las Vegas Wash were caffeine, carbamazepine (used to treat epilepsy), cotinine (a metabolite of nicotine), and dehydronifedipine (a metabolite of the antianginal Procardia). Less frequently detected compounds in samples collected from Las Vegas Wash were antibiotics (clarithromycin, erythromycin, sulfamethoxazole, and trimethoprim), acetaminophen (an analgesic and anti-inflammatory), cimetidine (used to treat ulcers), codeine (a narcotic and analgesic), diltiazem (an antihypertensive), and 1,7-dimethylxanthine (a metabolite of caffeine). Fewer compounds were detected in samples collected from Lake Mead than from Las Vegas Wash. Caffeine was detected in all samples collected from Lake Mead.

Mylar originals of the map sheets were scanned, and the resultant images were rectified to a mathematically-generated set of latitude and longitude registration points. Geologic linework was digitized from the rectified images on screen using ArcView (ver. 3.2), and the resultant shapefiles were converted to ArcInfo (ver. 7.2) coverages. Lines and polygons were then attributed; and the files were merged omtp a single ArcInfo database (quib24k).\nThis digital spatial database is one of many being created by the U.S. Geological Survey as an ongoing effort to provide geologic information in a geographic information system (GIS) for use in spatial analysis. This database can be queried in many ways to produce a variety of geologic maps. Digital base map data files (topography, roads, towns, rivers and lakes, etc.) are not included: they may be obtained from a variety of commercial and government sources.

The community has shifted from being dominated by several opportunistic species to a community where the species are more similar in abundance, a pattern that could be indicative of a more stable community that is subjected to less stress. In addition, two of the opportunistic species (Ampelisca abdita and Streblospio benedicti) that brood their young and live on the surface of the sediment in tubes have shown a continual decline in dominance coincident with the decline in metals. Heteromastus filiformis, a subsurface polychaete worm that lives in the sediment, consumes sediment and organic particles residing in the sediment, and reproduces by laying their eggs on or in the sediment has shown a concurrent increase in dominance. These changes in species dominance reflect a change in the community from one dominated by surface dwelling, brooding species to one with species with varying life history characteristics. Analysis of the reproductive activity of Macoma balthica shows increases in reproductive activity concurrent with the decline in metal concentrations in the tissue of this organism.

The goal of the program is to apply the DSS to U.S. Bureau of Reclamation projects in the western United States. The DSS was applied to the Reclamation's Yakima Project in the Yakima River Basin in eastern Washington. An important component of the DSS is the physical hydrology modeling. For the application to the Yakima River Basin, the physical hydrology component consisted of constructing four watershed models using the U.S. Geological Survey's Precipitation-Runoff Modeling System within the Modular Modeling System. The implementation of these models is described. To facilitate calibration of the models, mean annual streamflow also was estimated for ungaged subbasins. The models were calibrated for water years 1950-94 and tested for water years 1995-98. The integration of the models in the DSS for real-time water-management operations using an interface termed the Object User Interface is also described. The models were incorporated in the DSS for use in long-term to short-term planning and have been used in a real-time operational mode since water year 1999.","language":"ENGLISH","doi":"10.3133/ofr02404","usgsCitation":"Mastin, M.C., and Vaccaro, J.J., 2002, Watershed models for decision support in the Yakima River basin, Washington: U.S. Geological Survey Open-File Report 2002-404, 46 p., https://doi.org/10.3133/ofr02404.","productDescription":"46 p.","costCenters":[],"links":[{"id":4200,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/ofr02404/ ","linkFileType":{"id":5,"text":"html"}},{"id":176413,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49fee4b07f02db5f6e29","contributors":{"authors":[{"text":"Mastin, M.

The LVDA capability allows the principal directions of horizontal anisotropy to be different than the model-grid row and column directions, and for the directions to vary on a cell-by-cell basis within model layers. The HUF Package calculates effective hydraulic properties for model grid cells based on hydraulic properties of hydrogeologic units with thicknesses defined independently of the model layers. These hydraulic properties include, among other characteristics, hydraulic conductivity and a horizontal anisotropy ratio. Using the LVDA capability, horizontal anisotropy direction is defined for model grid cells within which one or more hydrogeologic units may occur. For each grid cell, the HUF Package calculates the effective horizontal hydraulic conductivity along the primary direction of anisotropy using the hydrogeologic-unit hydraulic conductivities, and calculates the effective horizontal hydraulic conductivity along the orthogonal anisotropy direction using the effective primary direction hydraulic conductivities and horizontal anisotropy ratios. The direction assigned to the model layer effective primary hydraulic conductivity is specified using a new data set defined by the LVDA capability, when active, to calculate coefficients needed to solve the ground-water flow equation. Use of the LVDA capability is illustrated in four simulation examples, which also serve to verify hydraulic heads, advective-travel paths, and sensitivities calculated using the LVDA capability. This version of the LVDA capability defines variable-direction horizontal anisotropy using model layers, not the hydrogeologic units defined by the HUF Package. This difference needs to be taken into account when designing model layers and hydrogeologic units to produce simulations that accurately represent a given field problem. This might be a reason, for example, to make model layer boundaries coincide with hydrogeologic-unit boundaries in all or part of a model grid.","language":"ENGLISH","doi":"10.3133/ofr02409","usgsCitation":"Anderman, E.R., Kipp, K., Hill, M.C., Valstar, J., and Neupauer, R., 2002, MODFLOW-2000, the U.S. Geological Survey modular ground-water model -- Documentation of the Model-Layer Variable-Direction Horizontal Anisotropy (LVDA) capability of the Hydrogeologic-Unit Flow (HUF) package: U.S. Geological Survey Open-File Report 2002-409, 61 p., https://doi.org/10.3133/ofr02409.","productDescription":"61 p.","costCenters":[],"links":[{"id":4201,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://water.usgs.gov/nrp/gwsoftware/modflow2000/ofr02-409.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":176414,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a7fe4b07f02db648ce1","contributors":{"authors":[{"text":"Anderman, Evan R.","contributorId":95505,"corporation":false,"usgs":true,"family":"Anderman","given":"Evan","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":242119,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kipp, K.L.","contributorId":96715,"corporation":false,"usgs":true,"family":"Kipp","given":"K.L.","affiliations":[],"preferred":false,"id":242120,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hill, Mary C. mchill@usgs.gov","contributorId":974,"corporation":false,"usgs":true,"family":"Hill","given":"Mary","email":"mchill@usgs.gov","middleInitial":"C.","affiliations":[{"id":5044,"text":"National Research Program - Central Branch","active":true,"usgs":true}],"preferred":true,"id":242116,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Valstar, Johan","contributorId":69224,"corporation":false,"usgs":true,"family":"Valstar","given":"Johan","email":"","affiliations":[],"preferred":false,"id":242118,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Neupauer, R.M.","contributorId":33381,"corporation":false,"usgs":true,"family":"Neupauer","given":"R.M.","affiliations":[],"preferred":false,"id":242117,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}
