Contamination is also present at a municipal landfill in the City of Waterbury that is upgradient from the industrial sites in the local ground-water-flow system. The study area, which lies in the Western Highlands of Connecticut, is in the Mad River Valley, a tributary to the Naugatuck River. Geohydrologic units (aquifer materials) include unconsolidated glacial sediments (surficial materials) and fractured crystalline (metamorphic) bedrock. Surficial materials include glacial till, coarse-grained andfine-grained glacial stratified deposits, and postglacial floodplain alluvium and swamp deposits. The ground-water-flow system in the surficial aquifer is complex because the hydraulic properties of the surficial materials are highly variable. In the bedrock aquifer, ground water moves exclusively through fractures. Hydrologic characteristics of the crystalline bedrock-degree of confinement, hydraulic conductivity, storativity, and porosity-are poorly defined in the study area. Further study is needed to adequately assess ground-water flow and contaminant migration under current or past hydrologic conditions. All known water-supply wells in the study area obtain water from the bedrock aquifer. Twenty households in a hillside residential area on Tosun Road currently obtain drinking water from private wells tapping the bedrock aquifer. The extent of contamination in the bedrock aquifer and the potential for future contamination from known sources of contamination in the surficial aquifer is of concern to regulatory agencies. Previous investigations have identified ground-water contamination by volatile organic compounds at the Nutmeg Valley Road site area. Contamination has been associated with on-site disposal of heavy metals, chlorinated and non-chlorinated volatile organic compounds, and cyanide. Concentrations of volatile organic compounds detected in water samples collected from bedrock wells during 1981-95 at the Nutmeg Valley Road site area show a general downward trend through time. Water samples collected from wells completed in surficial materials were not collected systematically, and a trend in concentration cannot be identified.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nInformation Services [distributor],","doi":"10.3133/ofr97219","issn":"0094-9140","usgsCitation":"Stone, J.R., Casey, G.D., Mondazzi, R., and Frick, T., 1997, Preliminary hydrogeologic assessment of a ground-water contamination area in Wolcott, Connecticut: U.S. Geological Survey Open-File Report 97-219, iv, 29 p. :ill.

Borehole and surface geophysical data were integrated with borehole textural data to characterize the Kings River alluvial fan sediments and to provide a framework for computer modeling of pesticide transport in ground water. Primary hydrogeologic facies units, such as gravel, coarse sand or gravel, fine sand, and silt and clay, were identified in cores collected from three borings located on a 4.6-kilometer transect of multilevel monitoring wells. Borehole geophysical logs collected from seven wells and surface geophysical surveys were used to extrapolate hydrogeologic facies to depths of about 82meters and to correlate the facies units with neighboring drilling sites. Thickness ranged from 0.3to 13 meters for sand and gravel units, and from 0.3 to 17 meters for silt and clay. The lateral extent of distinct silt and clay layers was mapped using shallow seismic reflection and ground-penetrating radar techniques. About 3.6 kilometers of seismic reflection data were collected; at least three distinct fine-grained layers were mapped. The depth of investigation of the seismic survey ranged from 34 to 107 meters below land surface, and vertical resolution was about 3.5 meters. The ground-penetrating radar survey covered 3.6kilometers and imaged a 1.5-meters thick, continuous fine-grained layer located at a depth of about 8 meters. Integrated results from the borehole sediment descriptions and geophysical surveys provided a detailed characterization over a larger areal extent than traditional hydrogeologic methods alone.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nInformation Services [distributor],","doi":"10.3133/ofr9746","issn":"0566-8174","usgsCitation":"Burow, K.R., Weissmann, G., Miller, R., and Placzek, G., 1997, Hydrogeologic facies characterization of an alluvial fan near Fresno, California, using geophysical techniques: U.S. Geological Survey Open-File Report 97-46, iv, 15 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr9746.","productDescription":"iv, 15 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":153029,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1997/0046/report-thumb.jpg"},{"id":51359,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1997/0046/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4adce4b07f02db686340","contributors":{"authors":[{"text":"Burow, Karen R. 0000-0001-6006-6667 krburow@usgs.gov","orcid":"https://orcid.org/0000-0001-6006-6667","contributorId":1504,"corporation":false,"usgs":true,"family":"Burow","given":"Karen","email":"krburow@usgs.gov","middleInitial":"R.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":186045,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Weissmann, G.S.","contributorId":50927,"corporation":false,"usgs":true,"family":"Weissmann","given":"G.S.","affiliations":[],"preferred":false,"id":186046,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Miller, R.

The most likely widespread and hazardous consequence of a future eruption will be for lahars (rapidly moving mudflows) to sweep down the entire length of the Sandy (including the Zigzag) and White River valleys. Lahars can be generated by hot volcanic flows that melt snow and ice or by landslides from the steep upper flanks of the volcano. Structures close to river channels are at greatest risk of being destroyed. The degree of hazard decreases as height above a channel increases, but large lahars can affect areas more than 30 vertical meters (100 vertical feet) above river beds. The probability of eruption-generated lahars affecting the Sandy and White River valleys is 1-in-15 to l-in-30 during the next 30 years, whereas the probability of extensive areas in the Hood River Valley being affected by lahars is about ten times less. The accompanying volcano-hazard-zonation map outlines areas potentially at risk and shows that some areas may be too close for a reasonable chance of escape or survival during an eruption. Future eruptions of Mount Hood could seriously disrupt transportation (air, river, and highway), some municipal water supplies, and hydroelectric power generation and transmission in northwest Oregon and southwest Washington.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr9789","issn":"0094-9140","usgsCitation":"Scott, W.E., Pierson, T., Schilling, S., Costa, J.E., Gardner, C.A., Vallance, J., and Major, J., 1997, Volcano hazards in the Mount Hood region, Oregon: U.S. Geological Survey Open-File Report 97-89, Report: ii, 14 p., 1 Map: 41.57 x 27.15 inches, https://doi.org/10.3133/ofr9789.","productDescription":"Report: ii, 14 p., 1 Map: 41.57 x 27.15 inches","numberOfPages":"16","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":153,"text":"California Volcano Observatory","active":false,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":155191,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_97_89.gif"},{"id":262718,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1997/0089/pdf/of1997-0089_map.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":262717,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1997/0089/","linkFileType":{"id":5,"text":"html"}},{"id":51680,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1997/0089/pdf/of1997-0089.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Oregon","otherGeospatial":"Mt.

The Minnesota Management Systems Evaluation Area (MSEA) project was part of a multi-scale, inter-agency initiative to evaluate the effects of agricultural management systems on water quality in the midwest corn belt. The research area was located in the Anoka Sand Plain about 5 kilometers southwest of Princeton, Minnesota. The ground-water-quality monitoring network within and immediately surrounding the research area consisted of 73 observation wells and 25 multiport wells. The primary objectives of the ground-water monitoring program at the Minnesota MSEA were to: (1) determine the effects of three farming systems on ground-water quality, and (2) understand the processes and factors affecting the loading, transport, and fate of agricultural chemicals in ground water at the site. This report presents well construction, geologic, water-level, chemical application, water-quality, and quality-assurance data used to evaluate the effects of farming systems on ground-water quality during 1991-95.

The stratigraphic units of the Edwards aquifer in south-central Uvalde County generally are porous and permeable. The stratigraphic units that compose the Edwards aquifer in south-central Uvalde County are the Devils River Formation in the Devils River trend; and the West Nueces, McKnight, and Salmon Peak Formations in the Maverick Basin. The Balcones fault zone is the principal structural feature in Uvalde County; however, the displacement along the fault zone is less in Uvalde County than in adjacent Medina and Bexar Counties to the east. The Uvalde Salient is a structural high in south-central Uvalde County, and consists of several closely connected crustal uplifts that bring Edwards aquifer strata to the surface generally forming prominent hills. The crustal uplifts forming this structural high are the remnants of intrusive and extrusive magnatic activity. Six primary faults—Cooks, Black Mountain, Blue Mountain, Uvalde, Agape, and Connor—cross the length of the study area from the southwest to the northeast juxtaposing the Lower Cretaceous Salmon Peak Formation at the surface in the northwestern part of the study area against Upper Cretaceous formations in the central part of the study area. In the study area, the porosity of the rocks in the Edwards aquifer is related to depositional or diagenetic elements along specific stratigraphic horizons (fabric selective) and to dissolution and structural elements that can occur in any lithostratigraphic horizon (not fabric selective). Permeability depends on the physical properties of the rock such as size, shape, distribution of pores, and fissuring and dissolution. The middle 185 feet of the lower part of the Devils River Formation, the upper part of the Devils River Formation, and the upper unit of the Salmon Peak Formation probably are the most porous and permeable stratigraphic zones of the Edwards aquifer in south-central Uvalde County.

Limited storage and low aquifer permeability restrict base flow to streams, and streamflows therefore decline rapidly once precipitation ceases. Shallow ground water and springs occur throughout the area, but because of the low permeability of aquifer materials, nearly all wells and springs have low yields. Water quality in streams, wells, and springs is generally good, but saline ground water has been reported on a number of drillers' logs for the study area and in several previous investigations of nearby areas. Further development of water resources in the Grand Ronde area is likely to be constrained by existing downstream water rights, the low permeability of geologic materials throughout the area, and possibly the intrusion of saline water. However, construction of facilities to store available water and thus compensate for low yields could provide a reliable, sustainable water supply for the Grand Ronde area.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri974040","collaboration":"Prepared in cooperation with the Confederated Tribes of the Grand Ronde Community of Oregon","usgsCitation":"McCarthy, K.A., Risley, J.C., Caldwell, R.R., and McFarland, W.D., 1997, Assessment of the water resources of the Grand Ronde area, Oregon: U.S. Geological Survey Water-Resources Investigations Report 97-4040, Report: v, 27 p.; 1 Plate: 33.33 x 37.16 inches, https://doi.org/10.3133/wri974040.","productDescription":"Report: v, 27 p.; 1 Plate: 33.33 x 37.16 inches","costCenters":[{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true}],"links":[{"id":120071,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1997/4040/report-thumb.jpg"},{"id":57473,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1997/4040/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":363940,"rank":3,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1997/4040/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Oregon","otherGeospatial":"Grand Ronde area","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -123.76,\n 44.9\n ],\n [\n -123.48,\n 44.9\n ],\n [\n -123.48,\n 45.25\n ],\n [\n -123.76,\n 45.25\n ],\n [\n -123.76,\n 44.9\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aa9e4b07f02db668017","contributors":{"authors":[{"text":"McCarthy, Kathleen A. mccarthy@usgs.gov","contributorId":1159,"corporation":false,"usgs":true,"family":"McCarthy","given":"Kathleen","email":"mccarthy@usgs.gov","middleInitial":"A.","affiliations":[],"preferred":true,"id":200153,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Risley, John C. 0000-0002-8206-5443 jrisley@usgs.gov","orcid":"https://orcid.org/0000-0002-8206-5443","contributorId":2698,"corporation":false,"usgs":true,"family":"Risley","given":"John","email":"jrisley@usgs.gov","middleInitial":"C.","affiliations":[{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true}],"preferred":true,"id":200151,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Caldwell, Rodney R. 0000-0002-2588-715X caldwell@usgs.gov","orcid":"https://orcid.org/0000-0002-2588-715X","contributorId":2577,"corporation":false,"usgs":true,"family":"Caldwell","given":"Rodney","email":"caldwell@usgs.gov","middleInitial":"R.","affiliations":[{"id":685,"text":"Wyoming-Montana Water Science Center","active":false,"usgs":true}],"preferred":true,"id":200152,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McFarland, William D.","contributorId":18738,"corporation":false,"usgs":true,"family":"McFarland","given":"William","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":200150,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}} ,{"id":26591,"text":"wri964282 - 1997 - Metal speciation in the Upper Arkansas River, Colorado, 1990-93","interactions":[],"lastModifiedDate":"2012-02-02T00:08:17","indexId":"wri964282","displayToPublicDate":"1997-09-01T00:00:00","publicationYear":"1997","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":342,"text":"Water-Resources Investigations Report","code":"WRI","active":false,"publicationSubtype":{"id":5}},"seriesNumber":"96-4282","title":"Metal speciation in the Upper Arkansas River, Colorado, 1990-93","language":"ENGLISH","publisher":"U.S. Geological Survey :\r\nBranch of Information Services [distributor],","doi":"10.3133/wri964282","usgsCitation":"Clark, M.L., and Lewis, M., 1997, Metal speciation in the Upper Arkansas River, Colorado, 1990-93: U.S. Geological Survey Water-Resources Investigations Report 96-4282, iv, 24 p. :ill., maps ;28 cm., https://doi.org/10.3133/wri964282.","productDescription":"iv, 24 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":118786,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1996/4282/report-thumb.jpg"},{"id":55459,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1996/4282/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4de4b07f02db62729d","contributors":{"authors":[{"text":"Clark, M.

The alluvial and volcanic Salt Basin \r\naquifer lies within a bolson, and the average depth to water in \r\nmost of the subbasin is approximately 250 feet. Concentrations of \r\nthe chlorofluorocarbons CFC-11, CFC-12, and CFC-113, as well as \r\ntritium, were measured in water from 10 wells in the study area. \r\nCFC-model recharge dates ranged from pre-1940 to the early \r\n1970's. Ground water in five wells had CFC-model dates of pre-1940 \r\nor pre-1945. Ground water in two wells had dates of the mid- to \r\nlate 1940's. Ground water from one well had a CFC-model recharge \r\nage of the early 1950's. Samples from the remaining two wells were \r\nmost probably contaminated in some manner and are probably \r\nunreliable. CFC-model ages were calculated independently for the \r\nthree chlorofluorocarbons, though the presence of volatile \r\norganic compounds affected agreement among them. Tritium \r\nactivities in the nine wells for which tritium was analyzed \r\nindicated pre-1953 recharge and thus agreed approximately with \r\nthe CFC-model dates.\r\n\r\n Ground water was analyzed for selected water-quality \r\nconstituents. Water from all wells met U.S. Environmental \r\nProtection Agency national primary and secondary drinking water \r\nstandards for all tested constituents except fluoride in samples \r\nfrom three wells.

The site, underlain by carbonate rock, was primarily corn and alfalfa fields; the median slope was 6 percent.Normal precipitation is about 42 inches per year. Average annual runoff was 11 percent and ground- water recharge was 37 percent of precipitation.Runoff quantity, suspended-sediment, and nutrient data, ground-water level and nutrient data, and precipitation-quantity data were collected for 21 months prior to, and 58 months after, pipe-outlet terrace construction. Data were analyzed by use of graphical, regression, covariate, cluster, Mann- Whitney Rank Sum test, and double-mass curvetechniques. Terracing changed runoff characteristics. Storm characteristics were similar throughout the study period. However, after terracing, storms producing less than 0.4 inch of precipitation rarely produced runoff. Total-storm discharge as a function of precipitation did not change significantly throughout the range of runoff-producing storms after terracing. Multiple-discharge peaks on hydrographs before terracing did not occur after terracing when hydrographs reflected the stepwisedraining of each terrace through the pipe outlet. After an initial 2-year period of terrace stabilization, suspended-sediment yield in runoff decreased significantly as a function of runoff. This result was expected because terracing decreased runoff energy, and because terrace ponding allowed time for sediment redeposition. Nitrate plus nitrite yields increased proportionally throughout the range of runoff during the post-terracing period relative to the pre- terracing period. After terracing, a combination of increased soil contact time and increased nitrification caused by wetter soils is believed to have increased nitrate concentrations in runoff. No significant change was found in yields of total nitrogen, ammonia plus organic nitrogen, or total phosphorus relative to runoff before and after terracing. Limited data suggest that fine-sediment particles (less than 0.62 micrometers in diameter), which continued to be discharged from the site, transported most of the phosphorus. Terracing did not significantly change the quantity of recharge to the carbonate aquifer. The mean annual water-table altitude did not change after terracing. Nitrate concentrations of ground water increased significantly at four of the site wells after terracing, probably because of increased contact time of the recharge with nutrient-rich soils in ponded terrace water. Qualitative evidence indicates that large decreases in nutrient requirements and nitrogen applications because of a crop change from corn to alfalfa upgradient of two site wells resulted in either no detectable change or a significant decrease in nitrate concentrations of ground water after terracing.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri944206","usgsCitation":"Lietman, P., Gustafson-Minnich, L., and Hall, D.W., 1997, Evaluation of agricultural best-management practices in the Conestoga River headwaters, Pennsylvania: Effects of pipe-outlet terracing on quantity and quality of surface runoff and ground water in a small carbonate-rock basin near Churchtown, Pennsylvania, 1983-89: U.S. Geological Survey Water-Resources Investigations Report 94-4206, vii, 62 p., https://doi.org/10.3133/wri944206.","productDescription":"vii, 62 p.","costCenters":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"links":[{"id":57174,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1994/4206/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":395191,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_48076.htm"},{"id":126888,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1994/4206/report-thumb.jpg"}],"country":"United States","state":"Pennsylvania","city":"Churchtown","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -75.9825,\n 40.1264\n ],\n [\n -75.9764,\n 40.1264\n ],\n [\n -75.9764,\n 40.1319\n ],\n [\n -75.9825,\n 40.1319\n ],\n [\n -75.9825,\n 40.1264\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4be4b07f02db6258df","contributors":{"authors":[{"text":"Lietman, P.

Forty‐four smallmouth bass Micropterus dolomieu of three size‐classes were radio‐tracked in Green Lake, Maine, during summer 1993 (10 June–1 September) to determine whether adult size influenced distribution and movement. Large smallmouth bass (>406 mm) used deep water (>8 m) more often than did small (248–279 mm) or medium‐sized (305–356 mm) smallmouth bass during the late summer (15 July–1 September). Large smallmouth bass also were found at middepths (4–8 m) significantly more often than were small individuals during late summer. Small fish used cover more frequently than large ones during early summer (10 June–13 July). Both small and medium‐sized individuals were associated with cover more frequently than large smallmouth bass were during the late summer. Small smallmouth bass exhibited significantly smaller summer total ranges than did large individuals, and mean active displacement differed among all three size‐classes.

We compared the diets among members of the diverse darter community of French Creek, Pennsylvania, in relation to seasonal prey availability, feeding ontogeny, and sex. Prey taxa and size attributes were characterized for nine syntopic darter species; taxon, size, and availability of macroinvertebrate prey were also analyzed from Surber samples. In general, darters fed opportunistically on immature insects; few taxa were consumed in greater proportions than they were found in the environment. Some variation in diet composition was expressed, however, among different life stages and species. Juvenile darters consumed smaller prey and more chironomids than did adults. Etheostoma blennioides and E. zonale consumed the fewest taxa (2–3), whereas E. maculatum, E. variatum, and Percina evides had the most diverse diets (7–10 taxa). Etheostoma maculatum, E. flabellare, E. variatum, and P. evides consumed larger prey (1–13 mm in standard length), whereas E. blennioides, E. caeruleum, E. camurum, E. tippecanoe, and E. zonale rarely consumed prey longer than 6 mm. Percina evides fed on larger prey, fewer chironomids, and more fish eggs than Etheostoma species. Females consumed more prey than males and overlapped less in diet composition with males during the spawning season than afterwards. Fish diets did not seem related to habitat use. Greater trophic partitioning was observed in April, when prey resources were scarce, than in July, when prey were abundant. Darter species fed opportunistically when prey were dense, whereas they partitioned food resources mainly through the prey size dimension when prey were less abundant. The divergence of darter diets during a period of low food availability may be attributed to interspecific competition. Alternatively, the greater abundance of large prey in April may have facilitated better prey size selectivity, resulting in less overlap among darter species.

Data that describe the physical characteristics of stream subbasins upstream from selected sites on streams in the Middle Minnesota-Little Cottonwood River Basin, located in south-central Minnesota are presented in this report. The physical characteristics are the drainage area of the subbasin, the percentage area of the subbasin covered only by lakes, the percentage area of the subbasin covered by both lakes and wetlands, the main-channel length, and the main-channel slope. Stream sites include outlets of subbasins of at least 5 square miles, outfalls of sewage treatment plants, and locations of U.S. Geological Survey low-flow, high-flow, and continuous-record gaging stations.

Ongoing analyses \r\nof the central portion of the Middle Rio Grande Basin by the U.S. \r\nGeological Survey (USGS) in cooperation with the City of \r\nAlbuquerque and other cooperators have shown that ground water in \r\nthe basin is not as readily accessible as earlier studies \r\nindicated. A more complete characterization of the ground-water \r\nresources of the entire Middle Rio Grande Basin is hampered by a \r\nscarcity of data in the northern and southern areas of the basin.\r\n\r\n The USGS Middle Rio Grande Basin Study is a 5-year effort by \r\nthe USGS and other agencies to improve the understanding of the \r\nhydrology, geology, and land-surface characteristics of the Middle \r\nRio Grande Basin. The primary objective of this study is to improve \r\nthe understanding of the water resources of the basin. Of \r\nparticular interest is to determine the extent of hydrologic \r\nconnection between the Rio Grande and the Santa Fe Group aquifer. \r\nAdditionally, ground-water quality affects the availability of \r\nwater supplies in the basin. Improving the existing USGS-\r\nconstructed ground-water flow model of the Middle Rio Grande Basin \r\nwill integrate all the various tasks that improve our knowledge of \r\nthe various components of the Middle Rio Grande water budget. Part \r\nof this improvement will be accompanied by extended knowledge of \r\nthe aquifer system beyond the Albuquerque area into the northern \r\nand southern reaches of the basin. Other improvements will be based \r\non understanding gained through process-oriented research and \r\nimproved geologic characterization of the deposits. The USGS will \r\nstudy the hydrology, geology, and land-surface characteristics of \r\nthe basin to provide the scientific information needed for water- \r\nresources management and for managers to plan for water supplies \r\nneeded for a growing population. \r\n\r\n To facilitate exchange of information among the many USGS \r\nscientists working in the Middle Rio Grande Basin, yearly technical \r\nmeetings are planned for the anticipated 5-year study. These \r\nmeetings provide an opportunity to present research results and \r\nplan new field efforts. This report documents the results of \r\nresearch presented at the first technical workshop held in Denver, \r\nColorado, in November 1996.\r\n\r\n The report is organized into this introduction, five chapters \r\nthat focus on USGS investigations in progress in the Middle Rio \r\nGrande Basin, and three appendixes with supplemental information. \r\nThe first chapter provides an overview of the USGS program in the \r\nbasin. The second chapter describes geographic data and analysis \r\nefforts in the basin. The third chapter details work being done on \r\nthe hydrogeologic framework of the basin. The fourth chapter \r\ndescribes studies on ground-water availability in the basin and is \r\ndivided into three areas of research: ground-water/surface-water \r\ninteraction, ground-water flow and aquifer properties, and \r\nrecharge. The fifth chapter is devoted to an overview of New Mexico \r\nDistrict Cooperative Program studies in the basin.

The county is located in \r\nthe Lower Colorado River Basin and the Rio Grande Basin, and the \r\nContinental Divide is the boundary between the two river basins. \r\nIncreases in water used for mining activities (coal, mineral, and \r\ngeothermal), irrigated agriculture, reservoir construction, or \r\ndomestic purposes could affect the quantity or quality of ground-\r\nwater and surface-water resources in the county.\r\n\r\n Parts of seven major drainage basins are within the two \r\nregional river basins in the county--Carrizo Wash, North Plains, \r\nRio Salado, San Agustin, Alamosa Creek, Gila, and San Francisco \r\nBasins. The San Francisco, Gila, and Tularosa Rivers typically \r\nflow perennially. During periods of low flow, most streamflow is \r\nderived from baseflow. The stream channels of the Rio Salado and \r\nCarrizo Wash Basins are commonly perennial in their upper reaches \r\nand ephemeral in their lower reaches. Largo Creek in the Carrizo \r\nWash Basin is perennial downstream from Quemado Lake and ephemeral \r\nin the lower reaches.\r\n\r\n Aquifers in Catron County include Quaternary alluvium and \r\nbolson fill; Quaternary to Tertiary Gila Conglomerate; Tertiary \r\nBearwallow Mountain Andesite, Datil Group, and Baca Formation; \r\nCretaceous Mesaverde Group, Crevasse Canyon Formation, Gallup \r\nSandstone, Mancos Shale, and Dakota Sandstone; Triassic Chinle \r\nFormation; and undifferentiated rocks of Permian age. Water in the \r\naquifers in the county generally is unconfined; however, confined \r\nconditions may exist where the aquifers are overlain by other units \r\nof lower permeability.\r\n\r\n Yields of ground water from the Quaternary alluvium in the \r\ncounty range from 1 to 375 gallons per minute. Yields of ground \r\nwater from the alluvium in the Carrizo Wash Basin are as much as \r\n250 gallons per minute for short time periods. North of the Plains \r\nof San Agustin, ground-water yields from the alluvium in the San \r\nAgustin Basin range from 1 to 10 gallons per minute.\r\n\r\n Irrigation wells completed in the Quaternary bolson fill \r\nproduce as much as 975 gallons per minute immediately east of the \r\ncounty. Water from the bolson fill in the Plains of San Agustin has \r\nspecific-conductance values generally ranging from 180 to 3,300 \r\nmicrosiemens per centimeter at 25 degrees Celsius (microsiemens/cm). \r\n\r\n Yields from the Gila Conglomerate generally range from 2 to 5 \r\ngallons per minute. Water samples from two springs from the Gila \r\nConglomerate have specific conductances of 289 and 381 microsiemens/cm. \r\n\r\n The Tertiary Datil Group is present in the Carrizo Wash, San \r\nAgustin, San Francisco, and Gila Basins. The Datil Group commonly \r\nis unconfined, but may be confined at depth. Water levels of wells \r\ncompleted in this unit range from 60 to 1,260 feet below land \r\nsurface. Wells completed in the Datil Group typically yield 1 to \r\n15 gallons per minute. Specific conductance of water from the \r\nDatil Group ranges from 210 to 820 microsiemens/cm. The Tertiary Baca \r\nFormation in the Carrizo Wash Basin produces 5 to 20 gallons per \r\nminute in stock wells. Water from wells completed in the Baca \r\nFormation has specific-conductance values ranging from 312 to 752 \r\nmicrosiemens/cm.\r\n\r\n Aquifers in Cretaceous rocks are present in the Carrizo Wash, \r\nNorth Plains, and Rio Salado Basins. The potential yield from wells \r\ncompleted in Cretaceous rocks in northwestern Catron County is from \r\n1 to 122 gallons per minute. Specific conductance of water from \r\nCretaceous rocks ranges from 210 microsiemens/cm in the Moreno Hill \r\nFormation to 4,490 microsiemens/cm in the Mancos Shale.

The Floridan aquifer system, a carbonate aquifer system composed of the Upper Floridan aquifer, a middle semi-confining unit, and the Lower Floridan aquifer, is the major source of water supply in northeastern Florida. The Lower Floridan aquifer is further subdivided into the Upper zone, a semi-confining unit, and the Fernandina permeable zone. As a result of increased withdrawals, heads in the aquifer system have declined and at the same time chloride concentrations have increased in the water from many wells in Duval County. A better understanding of the sources of and pathways for movement of brackish water is needed so that water managers can monitor the movement of brackish water and plan future water development. \r\n\r\nMost of the wells in Duval County deeper than 900 feet penetrate the Upper Floridan aquifer and the Upper zone of the Lower Floridan aquifer. Transmissivity estimates for these zones range from 2,000 to 194,000 feet squared per day. Permeability in the Upper zone of the Lower Floridan aquifer is primarily related to secondary porosity developed along bedding planes, joints, and fractures as a result of paleokarst processes. The Upper zone is about 300 to 500 feet thick in Duval County, based on the geophysical logs of about 40 wells ranging in depth from about 1,000 to 2,200 feet. In some areas the Upper zone has a single flow zone, but in other areas, two distinct flow zones are apparent. \r\n\r\nWater samples collected during this study confirm the continued increase in chloride concentrations in both the Upper Floridan aquifer and the Upper zone of the Lower Floridan aquifer. Most of the observed increases are in the eastern part of the county, but a pattern in the locations of wells yielding water with chloride increases is not discernible. In some areas, zones bearing brackish water are underlain by zones of fresher water, but in other areas, fresher water was not found beneath the brackish water. A single fracture or solution feature was the source of brackish water in several wells. \r\n\r\nThe most likely source of brackish water to the Upper zone of the Lower Floridan aquifer is the underlying Fernandina permeable zone, which contains freshwater in the western part of the county but saline water in the eastern part. The pathways for movement of saline water are interconnecting vertical and horizontal fracture or solution zones probably developed along paleokarst features that are not mappable from the land surface; therefore, a conventional monitor-well network probably would not provide early warning of saline-water intrusion. Continued monitoring of water-quality trends in water-supply wells, combined with collection of additional surface and borehole geophysical data, can provide an increased understanding of the movement of brackish water in the Floridan aquifer system.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri964242","usgsCitation":"Phelps, G.G., and Spechler, R., 1997, The relation between hydrogeology and water quality of the Lower Floridan Aquifer in Duval County, Florida, and implications for monitoring movement of saline water: U.S. Geological Survey Water-Resources Investigations Report 96-4242, v, 58 p., https://doi.org/10.3133/wri964242.","productDescription":"v, 58 p.","costCenters":[],"links":[{"id":159378,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":2331,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri964242/","linkFileType":{"id":5,"text":"html"}},{"id":409024,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_48572.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Florida","county":"Duval County","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"coordinates\": [\n [\n [\n -82,\n 30.5\n ],\n [\n -82,\n 30.1267\n ],\n [\n -81.333,\n 30.1267\n ],\n [\n -81.333,\n 30.5\n ],\n [\n -82,\n 30.5\n ]\n ]\n ],\n \"type\": \"Polygon\"\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a17e4b07f02db604256","contributors":{"authors":[{"text":"Phelps, G.

These samples were \r\nanalyzed for a broad host of constituents, including field \r\nparameters, major constituents, nutrients, dissolved organic \r\ncarbon, trace elements, radiochemicals, pesticides, and volatile \r\norganic compounds. The main purpose of this study was to observe \r\nthe quality of ground water in this part of the Rio Grande Valley \r\nstudy unit of the U.S. Geological Survey National Water-Quality \r\nAssessment program. The sampling effort was limited to the basin-\r\nfill aquifer beneath the above-defined reach of the Rio Grande \r\nflood plain because of the relative homogeneity of the \r\nhydrogeology, the large amount of ground-water use for public \r\nsupply, and the potential for land-use activities to affect the \r\nquality of ground water. Most of the wells sampled for the study \r\nare used for domestic purposes, including drinking water. Depths \r\nto the tops of the sampling intervals in the 30 wells ranged from \r\n10 to 345 feet below land surface, and the median was 161.5 feet; \r\nthe sampling intervals in most of the wells spanned about 10 feet \r\nor less. Quality-control data were collected at three of the \r\nwells.\r\n\r\n A significant amount of variation was found in the chemical \r\ncomposition of ground water sampled throughout the study area, \r\nbut the water generally was found to be of suitable chemical \r\nquality for use as drinking water, according to current \r\nenforceable standards established by the U.S. Environmental \r\nProtection Agency (EPA). Nutrients generally were measured at \r\nconcentrations near or below their method reporting limits. The \r\nmost dominant nutrient species was nitrite plus nitrate, at a \r\nmaximum concentration of 1.9 milligrams per liter (as N). Only \r\neight of the trace elements analyzed for had median \r\nconcentrations greater than their respective minimum reporting \r\nlevels. Water from one well exceeded the lifetime health advisory \r\nestablished by the EPA for molybdenum; water from a different well \r\nexceeded the proposed EPA maximum contaminant level for uranium. \r\nGross alpha and gross beta particle activities generally appeared \r\nto strongly correlate with quantities of uranium and potassium, \r\nrespectively, detected in ground water. However, water from one \r\nwell exceeded the EPA maximum contaminant level for gross alpha \r\nparticle activity and may exceed the EPA maximum contaminant \r\nlevel for beta particle and photon activity, although current \r\ndata on gross beta particle activities are not conclusive on this \r\npoint. Radon concentrations did not appear to directly correlate \r\nwith uranium concentrations. The herbicide prometon was the only \r\nsynthetic organic compound detected in ground water in the study \r\narea, and was detected in only one well, at a concentration of \r\n0.038 microgram per liter. This well is shallow and is not used \r\nfor drinking water. With the exception of the one detection of \r\nprometon, no strong evidence was found of effects on ground-water \r\nquality from human activities. Therefore, most of the water \r\nsampled probably recharged at the margins of the alluvial basins \r\nor recharged through the flood plain before human development \r\nbegan.\r\n\r\n With respect to major constituents, the concentrations of \r\ndissolved solids ranged from 209 to 3,380 milligrams per liter, \r\nand the median concentration was 409.5 milligrams per liter. \r\nThere is evidence that the overall chemical composition of ground \r\nwater in the study area may be affected by several processes, \r\nincluding cation exchange, feldspar weathering, calcite \r\ndissolution and precipitation, dissolution of volcanic glass, and \r\nmicrobial activity. Several chemical constituents in ground water \r\nshowed relatively distinct spatial patterns that appear to be \r\nrelated to one or more of these processes.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri964249","usgsCitation":"Bexfield, L.M., and Anderholm, S., 1997, Water-quality assessment of the Rio Grande Valley, Colorado, New Mexico and Texas: Ground-water quality in the Rio Grande flood plain, Cochiti Lake, New Mexico, to El Paso, Texas, 1995: U.S. Geological Survey Water-Resources Investigations Report 96-4249, viii, 93 p., https://doi.org/10.3133/wri964249.","productDescription":"viii, 93 p.","costCenters":[],"links":[{"id":410519,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_48578.htm","linkFileType":{"id":5,"text":"html"}},{"id":55001,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1996/4249/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":158430,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1996/4249/report-thumb.jpg"}],"country":"United States","state":"Texas","county":"Colorado, New Mexico, Texas","otherGeospatial":"Rio Grande Valley","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"coordinates\": [\n [\n [\n -106.5167,\n 35.6333\n ],\n [\n -106.8778,\n 35.6333\n ],\n [\n -106.8778,\n 31.8\n ],\n [\n -106.5167,\n 31.8\n ],\n [\n -106.5167,\n 35.6333\n ]\n ]\n ],\n \"type\": \"Polygon\"\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ae4b07f02db5fb523","contributors":{"authors":[{"text":"Bexfield, L.
