Using these characteristics, the U.S. Environmental Protection Agency's Stormwater Management Model (SWMM) was configured for basins in the study area. The data network for the model calibration consisted of four continuous rainfall gages and three continuous streamflow gages. The model was calibrated, using observed data from three runoff events, by minimizing objective functions representing peak discharge, volume of runoff, and time to peak discharge from the beginning of simulation. The absolute mean percentage difference between the simulated and observed data for peak discharge, volume of runoff, and time to peak discharge are 9.47, 10.8, and 19.6 percent. A sensitivity analysis of SWMM parameters was performed on a simplified drainage basin. The output of runoff (volume, peak, and timing) in SWMM was determined to be most sensitive to subarea width, percentage impervious area, saturated hydraulic conductivity, and initial moisture deficit. The volume of runoff was affected by percentage impervious area, saturated hydraulic conductivity, and initial moisture deficit. The peak flow rate was affected by subcatchment width and percentage impervious area, whereas the time to peak was affected by subcatchment width. The model also was determined to be sensitive to the time step in the streamflow routing part.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri944019","usgsCitation":"Holmes, R., and East, J.W., 1994, Simulation of rainfall-runoff for basins in the Rolla, Missouri, area: U.S. Geological Survey Water-Resources Investigations Report 94-4019, vii, 24 p., https://doi.org/10.3133/wri944019.","productDescription":"vii, 24 p.","costCenters":[],"links":[{"id":411149,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_47930.htm","linkFileType":{"id":5,"text":"html"}},{"id":56571,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1994/4019/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":158794,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1994/4019/report-thumb.jpg"}],"country":"United States","state":"Missouri","city":"Rolla","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"coordinates\": [\n [\n [\n -91.87591911661391,\n 38.03597634320698\n ],\n [\n -91.87591911661391,\n 37.80120519183451\n ],\n [\n -91.61055977166683,\n 37.80120519183451\n ],\n [\n -91.61055977166683,\n 38.03597634320698\n ],\n [\n -91.87591911661391,\n 38.03597634320698\n ]\n ]\n ],\n \"type\": \"Polygon\"\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a19e4b07f02db605d5a","contributors":{"authors":[{"text":"Holmes, Robert R.

On the basis of geohydrologic information, a qualitative assessment of the possible effects of this injection indicates that fresh groundwater in certain areas of the Duchesne River formation may be more susceptible than water in other areas to becoming mixed with injected oil-production water. The reason for this possible mixing is because these areas containing the susceptible groundwater lack a thick shale layer above the disposal zone, as indicated in geophysical logs. In other areas, naturally occurring moderately saline water exists at shallow depths and may be withdrawn from water wells completed more than 200 ft below land surface. Additional geohydrologic information will need to be collected to allow investigators to make a quantitative determination of the rate of horizontal and vertical migration of injected oil-production water within and above the disposal zone.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri924043","usgsCitation":"Freethey, G.W., 1994, Maps summarizing geohydrologic information in an area of salt-water disposal, eastern Altamont-Bluebell petroleum field, Uinta Basin, Utah: U.S. Geological Survey Water-Resources Investigations Report 92-4043, 2 Plates: 21.26 × 25.88 inches and 21.26 × 26.33 inches, https://doi.org/10.3133/wri924043.","productDescription":"2 Plates: 21.26 × 25.88 inches and 21.26 × 26.33 inches","costCenters":[],"links":[{"id":171516,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":393973,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_47621.htm"},{"id":82078,"rank":401,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1992/4043/plate-2.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":82077,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/wri/1992/4043/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Utah","otherGeospatial":"eastern Altamont-Bluebell petroleum-field, Uinta Basin","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -110.1803,\n 40.2722\n ],\n [\n -109.8589,\n 40.2722\n ],\n [\n -109.8589,\n 40.4775\n ],\n [\n -110.1803,\n 40.4775\n ],\n [\n -110.1803,\n 40.2722\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a1ae4b07f02db6063d5","contributors":{"authors":[{"text":"Freethey, Geoffrey W.","contributorId":25570,"corporation":false,"usgs":true,"family":"Freethey","given":"Geoffrey","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":230397,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":70017085,"text":"70017085 - 1994 - Submerged and eroded drumlins off northeastern Massachusetts","interactions":[],"lastModifiedDate":"2017-11-05T10:16:45","indexId":"70017085","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1994","noYear":false,"publicationType":{"id":2,"text":"Article"},"publicationSubtype":{"id":10,"text":"Journal Article"},"seriesTitle":{"id":1801,"text":"Geomorphology","active":true,"publicationSubtype":{"id":10}},"title":"Submerged and eroded drumlins off northeastern Massachusetts","docAbstract":"Streamlined, oval-shaped, oriented topographic highs in Massachusetts Bay are identified as the erosional remnants of drumlins. The topographic highs correlate with outlines of lag gravel deposits on the sea floor and both the highs and lag gravel seafloor footprint have a distinct east-southeast long axis trend. This trend is similar to the preferred orientation of the long axes of drumlins in the Boston Basin and indicates the flow direction of the late Wisconsinan Laurentide Ice Sheet. Modification of the drumlins occurred during two passages of the shoreline, the first during the late Wisconsinan regression when the drumlins were only slightly eroded. The second passage of the shoreline occurred during the marine transgression, when erosion, in the form of cliff-face retreat, removed the upper part of the drumlins.

As part of this study, data from pumped-well tests and instantaneous-rechange tests (slug tests) of wells completed in the glacial-deposit and carbonate-rock aquifers were compiled from reports and information on file with State agencies, environmental consulting firms, drilling firms, municipalities, universities, and the USGS. The data, from 73 counties in Ohio and Indiana, were entered into a computerized data base in a spreadsheet format and subsequently into a geographic information system (GIS).\r\n\r\nAquifer-characteristics data from this compilation include the results of 105 pumped-well tests and 39 slug tests in wells completed in glacial deposits, 174 pumped-well tests in wells completed in the carbonate-rock aquifer, and 4 slug tests in wells completed in limestones and shales of Ordovician age. Transmissivities from the pumped-well tests in wells completed in glacial till and glacial-deposit aquifers (sands and gravels) range from 1.54 to 69,700 feet squared per day. Storage coefficients or specific yields range from 0.00002 to 0.38 at these wells. Horizontal-hydraulic conductivities from the slug tests in wells completed in glacial-deposit aquifers range from 0.33 to 1,000 feet per day. Transmissivities from the pumped-well tests in wells completed in the carbonate-rock aquifer range from 70 to 52,000 feet squared per day. Storage coefficient or specific yields at these wells range from 0.00001 to 0.05. Horizontal hydraulic conductivities from the slug tests in wells completed in limestones and shales of Ordovician age range from 0.0016 to 12 feet per day. These data are summarized in tables and figures within this report.\r\n\r\nThe collection and compilation of selected aquifer-characteristic data for the glacial-deposit and carbonate-rock aquifers within the Midwestern Basin and Arches Region of Shaver (1985) are an essential part of the Midwestern Basins and Arches Regional Aquifer-Systems Analysis (Midwestern Basins and Arches RASA) project of the U.S. Geological Survey (USGS). Specifically, the data are needed to help describe ground-water flow in the regional aquifer system, which isone of the objectives of the Midwestern Basins and Arches RASA project (Bugliosi, 1990). To meet this objective, the Midwestern Basins and Arches RASA began subprojects in the Ohio and Indiana offices of the USGS to collect and compile available aquifer-characteristics data from aquifer tests of the glacial-deposit and carbonate-rock aquifers. The data were not reanalyzed to verify accuracy because of time constraints and insufficient data in many cases.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr93627","usgsCitation":"Joseph, R.L., and Eberts, S.M., 1994, Selected data on characteristics of glacial-deposit and carbonate-rock aquifers, Midwestern Basin and Arches region: U.S. Geological Survey Open-File Report 93-627, vi, 43 p., https://doi.org/10.3133/ofr93627.","productDescription":"vi, 43 p.","costCenters":[],"links":[{"id":403940,"rank":2,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_12784.htm","linkFileType":{"id":5,"text":"html"}},{"id":49054,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1993/0627/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":152037,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1993/0627/report-thumb.jpg"}],"country":"United States","state":"Illinois, Indiana, Kentucky, Ohio, West Virginia","otherGeospatial":"Midwestern Basin and Arches Region","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -88.092,\n 37.771\n ],\n [\n -80.517,\n 37.771\n ],\n [\n -80.517,\n 41.983\n ],\n [\n -88.092,\n 41.983\n ],\n [\n -88.092,\n 37.771\n ]\n ]\n ]\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a08e4b07f02db5fa539","contributors":{"authors":[{"text":"Joseph, R.

From the beginning of development of the High Plains aquifer to 1980, water levels declined throughout much of the area; the declines exceeded 100 feet in parts of the central and southern High Plains. From 1980 to 1992, water levels continued to decline in these same areas, but at a slightly slower overall annual rate. This slower rate of decline was associated, in part, with a decrease in ground-water application for irrigated agriculture and above normal precipitation throughout the High Plains during 1980-91. Declines exceeding 20 feet were common from 1980 to 1992 in areas of intense irrigation development in Kansas, New Mexico, Oklahoma, and Texas. In the northern High Plains, declines of 10 to 20 feet from 1980 to 1992 were widespread in northeastern Colorado, southwestern Nebraska, and the Nebraska Panhandle. Water levels were generally stable from 1980 to 1992 in most other areas of the High Plains. In a large area in the southern High Plains of Texas, however, water-level rises exceeded 20 feet. Also, scattered rises of 5 to 10 feet occurred in eastern Nebraska. The estimated average area-weighted water-level change, from 1991 to 1992 was -0.55, even though precipitation was well-above normal in 1991 in the High Plains. Water- level declines of 3 to 5 feet were widespread in the intensively irrigated areas of southwestern Kansas and the northern part of the Southern High Plains of Texas. These large declines were not closely related to 1991 precipitation patterns in those areas. Declines of 1 to 3 feet were common throughout the intensively irrigated areas of the Northern High Plains and the less intensively irrigated areas of the Central and Southern High Plains. Water levels continued to rise, generally 1 to 3 feet in the extreme Southern High Plains of Texas. Rises of 1 to 3 feet also occurred in parts of northeastern and central Nebraska.

The study was part of a four-year assessment of non-point source pollution in the Minnesota River Basin. Runoff from tributary watersheds was identified as the primary source of suspended sediment and nutrients in the Minnesota River mainstem. Suspended-sediment, phosphorus, and nitrate concentrations were elevated in all major tributaries during runoff, but tributaries in the south-central and eastern part of the basin produce the highest annual loading to the mainstem because of higher annual precipitation and runoff in that part of the basin. Particle-size analyses showed that most of the suspended sediment in transport consisted of silt- and clay-size material. Phosphorus enrichment was indicated throughout the mainstem by total phosphorus concentrations that ranged from 0.04 to 0.48 mg/L with a median value of 0.22 mg/L, and an interquartile range of 0.15 to 0.29 mg/L. Nitrate concentrations periodically exceeded drinking water standards in tributaries draining the south-central and eastern part of the basin. Oxygen demand was most elevated during periods of summer low flow. Correlations between levels of biochemical oxygen demand and levels of algal productivity suggest that algal biomass comprises much of the oxygen-demanding material in the mainstem. Transport of sediment, nutrients, and organic carbon within the mainstem was found to be conservative, with nearly all tributary inputs being transported downstream. Uptake and utilization of nitrate and orthophosphorus was indicated during low flow, but at normal and high flow, inputs of these constituents greatly exceeded biological utilization.

The Seward terrane, an area 150 by 150 km in the central and eastern peninsula, is dominated by Precambrian(?) and early Paleozoic blueschist-, greenschist-, and amphibolite-facies schist and marble, and intruded by three suites of granitic rocks. The York terrane, roughly 100 by 75 km, occupies western Seward Peninsula and the Bering Straits region; it is composed of Ordovician, Silurian, Devonian, Mississippian, and possibly older limestone, argillaceous limestone, dolostone, and phyllite, which are cut by a suite of Late Cretaceous tin-bearing granites. The boundary between the Seward and York terranes is poorly exposed but is thought to be a major thrust fault because of its sinuous map trace, a discontinuity in metamorphic grade, and differences in stratigraphy across the boundary (Travis Hudson, oral communication, 1984). The boundary between the Seward terrane and the Yukon-Koyukuk province to the east is complicated by vertical faults (the Kugruk fault Zone of Sainsbury, 1974) and obscured by Cretaceous and Tertiary cover.
The Seward Peninsula heretofore was thought to consist largely of rocks of Precambrian age (Sainsbury, 1972, 1974, 1975; Hudson, 1977), Microfossil data, however, indicate that many of the rocks considered to be Precambrian are early Paleozoic in age (Till and others, 1986; Dumoulin and Harris, 1984; Dumoulin and Till, 1985; Till and others, 1983; Wandervoort, 1985). It is likely that Precambrian rocks are a minor part of the stratigraphy of the Seward Peninsula.

Physiographically, this subcontinent, which we name Denalia, is a bulge in the continental platform in the vicinity of Alaska, the Chukotsk Peninsula, and the broad continental shelf of the Bering Sea. The bulge is convex to the south and is bounded on the east and west by constrictions in the width of the continental platform and on the north and south by the edge of the continental shelf (Fig. 1). Tectonically, Denalia is characterized by geologic youthfulness and complexity, an abundance of convergent and transcurrent faults, and absence of autochthonous cratonic rocks. It contains a profusion of lithotectonic terranes of diverse origin and age that were emplaced in late Mesozoic and Cenozoic time. In addition, it includes the superimposed Cenozoic Aleutian arc and subduction zone and the Queen Charlotte-Fairweather transform fault system. Parts of Denalia were created by pre-middle Mesozoic tectonic events, but these took place elsewhere, before the affected rocks were tectonically transported and incorporated into the landmass of Denalia. Except for a small area in the Porcupine Plateau region along the Alaska-Yukon boundary, the only Precambrian rocks that have been recognized in the subcontinent are in tectonically emplaced fragments, the largest of which is the Arctic Alaska terrane in the Brooks Range, Arctic Foothills, and Arctic Foothills.

These reflections are interpreted as structural features of crustal-scale subdivisions within the Grenville Orogen. Broadly deformed, imbricated, and overlapping thrust sheets within the western Central Metasedimentary Belt are succeeded to the west by a complex zone of easterly dipping, apparent thrust faults that are interpreted as a southwest subsurface extension of the boundary zone between the Central Metasedimentary Belt and the Central Gneiss Belt. The interpreted Central Metasedimentary Belt boundary zone has a characteristic magnetic anomaly that provides a link from the adjacent ends of lakes Ontario and Erie to structures exposed 150 km to the north. Less reflective, west-dipping events are interpreted as structures within the eastern Central Gneiss Belt. The seismic interpretation augments current tectonic models that suggest the exposed ductile structures formed at depth as a result of crustal shortening along northwest-verging thrust faults. Relatively shallow reflections across the boundary region suggest local, Late Proterozoic extensional troughs containing post-Grenville sediments, preserved possibly as a result of pre-Paleozoic reactivation of basement structures.

A shear zone bounded transition between the Elzevir and Frontenac terranes exposed north of Lake Ontario is linked to a seismically defined shear zone beneath central Lake Ontario by prominent aeromagnetic and gravity anomalies, easterly dipping wide-angle reflections, and fractures in Paleozoic strata. We suggest the central Lake Ontario zone represents crustal-scale deformation along an Elzevir–Frontenac boundary zone that extends from outcrop to the south shore of Lake Ontario.Seismic images from Lake Ontario and the exposed western Central Metasedimentary Belt are dominated by crustal-scale shear zones and reflection geometries featuring arcuate reflections truncated at their bases by apparent east-dipping linear reflections. The images show that zones analogous to the interpreted Grenville Front Tectonic Zone are also present within the Central Metasedimentary Belt and support models of northwest-directed crustal shortening for Grenvillian deep crustal deformation beneath most of southeastern Ontario.A Precambrian basement high, the Iroquoian high, is defined by a thinning of generally horizontal Paleozoic strata over a crestal area above the basement shear zone beneath central Lake Ontario. The Iroquoian high helps explain the peninsular extension into Lake Ontario forming Prince Edward County, the occurrence of Precambrian inlier outcrops in Prince Edward County, and Paleozoic fractures forming the Clarendon–Linden structure in New York.

Parts of the landfill are below the water table. Surface-resistivity measurements and water-quality analyses indicate that leachate-enriched ground water along the eastern perimeter of the landfill has moved about 500 feet eastward toward an adjacent lake. Concentrations of chloride and nutrients within the leachate-enriched ground water were greater than background concentrations. The surficial aquifer system in the area of the landfill consists primarily of sand of moderate permeability, from land surface to a depth of about 68 feet deep, and consists of sand interbedded with sandstone and limestone of high permeability from a depth of about 68 feet to a depth of 200 feet. The potentiometric surface in the landfill is higher than that in adjacent areas to the east, indicating ground-water movement from the landfill toward a lake to the east. \r\n\r\nSteady-state simulation of ground-water flow was made using a telescoping-grid technique where a model covering a large area is used to determine boundaries and fluxes for a finer scale model. A regional flow model encompassing a 500-square mile area in southeastern Palm Beach County was used to calculate ground-water fluxes in a 126.5-square mile subregional area. Boundary fluxes calculated by the subregional model were then used to calculate boundary fluxes for a local model of the 3.75-square mile area representing the Lantana landfill site and vicinity. Input data required for simulating ground-water flow in the study area were obtained from the regional flow models, thus, effectively coupling the models. Additional simulations were made using the local flow model to predict effects of possible remedial actions on the movement of solutes in the ground-water system. Possible remedial actions simulated included capping the landfill with an impermeable layer and pumping five leachate recovery wells. Results of the flow analysis indicate that the telescoping grid modeling approach can be used to simulate ground-water flow in small areas such as the Lantana landfill site and to simulate the effects of possible remedial actions. \r\n\r\nWater-quality data indicate the leachate-enriched ground water is divided vertically into two parts by a fine sand layer at about 40 to 50 feet below land surface. Data also indicate the extent of the leachate-enriched ground-water contamination and concentrations of constituents seem to be decreasing over time.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/wri924107","usgsCitation":"Russell, G., and Wexler, E.J., 1993, Hydrogeology and simulation of ground-water flow near the Lantana Landfill, Palm Beach County, Florida: U.S. Geological Survey Water-Resources Investigations Report 92-4107, v, 55 p., https://doi.org/10.3133/wri924107.","productDescription":"v, 55 p.","costCenters":[{"id":27821,"text":"Caribbean-Florida Water Science Center","active":true,"usgs":true}],"links":[{"id":124674,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1992/4107/report-thumb.jpg"},{"id":58322,"rank":299,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1992/4107/wri924107.pdf","text":"Report","size":"14.3 MB","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Florida","county":"Palm Beach County","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"type\": \"Polygon\",\n \"coordinates\": [\n [\n [\n -80.4913330078125,\n 26.367263860129366\n ],\n [\n -79.84588623046874,\n 26.367263860129366\n ],\n [\n -79.84588623046874,\n 26.990618722964737\n ],\n [\n -80.4913330078125,\n 26.990618722964737\n ],\n [\n -80.4913330078125,\n 26.367263860129366\n ]\n ]\n ]\n }\n }\n ]\n}","contact":"Caribbean-Florida Water Science Center

Similarities in geology and potential field data that have in the past been noted among the regions of southern Alaska, southern Vancouver Island, and central California are now seen to be accompanied by similarities in deep crustal structure. A number of tectonic elements have been identified in the deep structure along transects in these three regions, although not all elements are present along each transect. These elements are (A) an actively subducting oceanic plate and (B) an overriding continental plate that consists of (1) a Cenozoic accretionary prism, (2) a Mesozoic accretionary prism, (3) a backstop to the Mesozoic prism, (4) a tectonically underplated body of oceanic rocks, and (5) a crustal root. The Mesozoic prism is in some cases an underthrust body (type 2a) but in other cases forms the principal component of a landward verging tectonic wedge (type 2b). The technically underplated body of oceanic rocks extends landward from the fault contact between the Cenozoic and Mesozoic prisms to a point beneath the backstop. The crustal root lies beneath the backstop and landward of the underplated body. All of these elements are interpreted to be present along the Alaskan and Vancouver Island transects. In Alaska the underplated body is interpreted to be fragments of the Kula plate; the same may be true at Vancouver Island. These two transects appear to differ in that, in Alaska, the Mesozoic prism, in one interpretation, is the principal component of a tectonic wedge (type 2b), whereas at Vancouver Island, it is an underthrust body (type 2a). Along the central California transect, active subduction is no longer taking place, and the San Andreas fault has removed the Cenozoic prism from this region of the North American plate. On the North American plate (i.e., east of the San Andreas fault), the Mesozoic prism, interpreted as the main component of a tectonic wedge (type 2b), and the backstop to the Mesozoic prism are present. There is, however, no clear evidence of tectonically underplated oceanic rocks, and the crust is thin (no root). In both Alaska and Vancouver Island, the Mesozoic prisms above the underplated bodies experienced low-pressure/high-temperature metamorphism at about the time of tectonic underplating; no such metamorphism is currently exposed in California. The metamorphism may have been caused by the underplating of young, hot oceanic crust, or, alternatively, by subduction of an oceanic ridge. The presence of a tectonic wedge (type 2b) in Alaska and California and the absence of such a wedge at Vancouver Island could arise either from the fact that in the former two locations the Mesozoic prisms were more voluminous, owing to either more rapid trench sedimentation or more rapid convergence, or to the possibility that at the latter location the Mesozoic prism was juxtaposed with the backstop primarily by strike-slip faulting.

The biological and chemical data for each well were grouped according to eight of the nine principal aquifers in the State and analyzed for local and regional variation within and among these aquifers. Water samples from 45 percent of the wells statewide tested positive for fecal cot[form or streptococci bacteria. Regionally, samples from 20 percent of the wells in the primarily unconsoli- dated sedimentary aquifers in western Tennessee tested positive for either or both bacteria, compared with samples from 54 percent of the wells in the consolidated bedrock aquifers in the central and eastern parts of the State. Although nitrate nitrogen equaled or exceeded the 10.0 milligrams per liter primary drinking-water standard in only 3 percent of the wells sampled statewide, samples from 20 percent of the wells had nitrate nitrogen concentrations that exceeded 3.00 milligrams per liter possibly indicating human influence on ground-water quality. Estimated total concentrations of organic compounds were less than 5 micrograms per liter in samples from 92 percent of the wells statewide. Concentrations of iron and manganese equaled or exceeded their secondary standards of 300 and 50 micrograms per liter in samples from 35 and 25 percent of the wells, respectively, with the largest concentrations identified in samples from the alluvial and Pennsylvanian sandstone aquifers. Samples from 25 percent of the wells, had a pH below the lower secondary standard of 6.5 units, with most of these samples from the unconsolidated sedimentary aquifers in western Tennessee.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nBooks and Open-File Reports Section [distributor],","doi":"10.3133/wri924186","usgsCitation":"Carmichael, J.K., and Bennett, M.W., 1993, Reconnaissance of quality of water from farmstead wells in Tennessee, 1989-90: U.S. Geological Survey Water-Resources Investigations Report 92-4186, iv, 43 p. :ill., maps ;28 cm.

Withdrawals from this aquifer for public water supply and for agricultural, industrial, and domestic water uses totalled about 3.0 million gallons per day in 1988. Some wells in the valley yield as much as 310 gallons per minute from the alluvial deposits along Rio Gurabo near Gurabo and near Juncos. Wells used at dairy farms in the area commonly yield about 30 gallons per minute. The potentiometric surface of the alluvial aquifer varies seasonally and generally is highest near the end of December and lowest in April. Transmissivity of the alluvial aquifer, estimated from specific capacity and slug test data, ranges from 65 to 4,800 feet squared per day. The estimated specific yield of the water-table is about 10 to 15 percent. The amount of water stored in the aquifer is estimated to be about 122,000 acre-feet. Analyses of ground-water samples revealed the presence of two distinct problems-- high natural concentrations of iron and manganese, and localized areas of human- related contamination scattered throughout the valley. The ground water is a calcium-bicarbonate type and typically has dissolved solids concentrations of less than 500 milligrams per liter.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri914079","usgsCitation":"Puig, J.C., and Rodriguez, J.M., 1993, Ground-water resources of the Caguas-Juncos Valley, Puerto Rico: U.S. Geological Survey Water-Resources Investigations Report 91-4079, v, 52 p., https://doi.org/10.3133/wri914079.","productDescription":"v, 52 p.","costCenters":[],"links":[{"id":58090,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1991/4079/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":123312,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1991/4079/report-thumb.jpg"},{"id":414050,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_47497.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Puerto Rico","otherGeospatial":"Caguas-Juncos Valley","geographicExtents":"{\n \"type\": \"FeatureCollection\",\n \"features\": [\n {\n \"type\": \"Feature\",\n \"properties\": {},\n \"geometry\": {\n \"coordinates\": [\n [\n [\n -66.0833,\n 18.3083\n ],\n [\n -66.0833,\n 18.1667\n ],\n [\n -65.833,\n 18.1667\n ],\n [\n -65.833,\n 18.3083\n ],\n [\n -66.0833,\n 18.3083\n ]\n ]\n ],\n \"type\": \"Polygon\"\n }\n }\n ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a9ae4b07f02db65d474","contributors":{"authors":[{"text":"Puig, J.
