The USGS office in Tallahassee acts as the liaison for all studies conducted by USGS scientists in Florida. Water resources activities are conducted not only from the office in Tallahassee, but also from offices in Miami, Tampa, and Altamonte Springs (Orlando). Scientists in these offices investigate surface water, ground water and water quality in Florida, working in cooperation with other Federal, State and local agencies and organizations. \rThe USGS Center for Coastal Geology and Regional Marine Studies was established in St. Petersburg in 1988, in cooperation with the University of South Florida. The Center conducts a wide variety of research on mineral resources and on coastal and regional marine problems, including coastal erosion, climate change, wetlands deterioration, and coastal pollution. A USGS mapping office is located in St. Petersburg. Also, the Earth Science Information Center (ESIC) in Tallahassee provides USGS information to customers and directs inquiries to the appropriate USGS office or State agency on earth science topics, particularly those related to cartography, geography, aerial photography, and digital data. Biologists at the USGS Florida Caribbean Science Center, located in Gainesville, conduct biological and ecosystem studies in Florida, Puerto Rico, and the Virgin Islands.

The deepest sediments, the Donoho Creek Formation (545-475.7 ft), consist of 69.3 ft of muddy calcareous sand of marine origin. This formation is placed within the upper Campanian calcareous nannofossil Subzone CC 22c. The overlying Peedee Formation (475.7-367.1 ft) in the core consists of 108.6 ft of silty clay of marine origin. It is placed in upper Maastrichtian calcareous nannofossil Subzones CC 25b, CC 26a, and CC 26b. Combined fossil and paleomagnetic information indicates nearly continuous deposition. Foraminifers indicate an outer neritic paleobathymetric setting. The Rhems Formation sensu stricto (367.1-267.3 ft) consists of 99.8 ft of silty clay, muddy sand, and minor calcite-cemented, shelly sand of marine origin. It is apparently the product of rapid sediment accumulation during a short period of time in the early Paleocene (calcareous nannofossil Zone NP 1). The upper part of the Rhems Formation sensu Bybell and others (1998) (267.3-237.4 ft) consists of 29.9 ft of calcite-cemented muddy sand and burrowed fine sand of marine origin. It is placed in calcareous nannofossil Zone NP 4 and, because it shows normal polarity, likely represents the upper part of the lower Paleocene. This unit may be correlative with the lower part of the Lower Bridge Member of the Williamsburg Formation in its type area. The Lower Bridge Member of the Williamsburg Formation (237.4-125.0 ft) has an unconformable contact at 205.0 ft that divides the member into lower muddy sand beds and upper calcareous clay beds. Both are placed in the upper Paleocene calcareous nannofossil Zone NP 5. The Chicora Member of the Williamsburg Formation (125-51.5 ft) consists of 73.5 ft of muddy, shelly sand of marine origin. It is poorly dated but includes late Paleocene nannofossils (Zones NP 5 and NP 6). A mollusk-bryozoan limestone (51.5-42.0 ft) above the Chicora Member of the Williamsburg yields early Eocene calcareous nannofossils representing both Zone NP 9/10 and Zone NP 12, together with pollen and dinocysts that are younger.\r\n\r\nSediments of middle and late Eocene, Oligocene, Miocene, and Pliocene ages were not recovered in the Santee Coastal Reserve core. The upper 42.0 ft of sediments represent Quaternary deposits and are included in the Wando Formation (42.0-28.0 ft) and the informal Silver Bluff beds (28.0-0 ft).","language":"ENGLISH","doi":"10.3133/ofr99308A","usgsCitation":"Edwards, L.E., Gohn, G.S., Self-Trail J.M., Prowell, D., Bybell, L., Bardot, L.P., Firth, J.V., Huber, B., Frederiksen, N.O., and MacLeod, K., 1999, Physical stratigraphy, paleontology, and magnetostratigraphy of the USGS-Santee Coastal Reserve core (CHN-803), Charleston County, South Carolina: U.S. Geological Survey Open-File Report 99-308, 36 p. , https://doi.org/10.3133/ofr99308A.","productDescription":"36 p.

The tidal Potomac River and Potomac Estuary is an important component of the Chesapeake Bay system to which these requirements can be applied. The SAV habitat requirements are formulated as threshold criteria that certain critical water-quality characteristics must satisfy during the SAV growing season. A multivariate scoring system based on these criteria was developed in order to synopsize water quality conditions during the 1983-1997 SAV growing seasons. Chesapeake Bay habitat criteria scores are displayed relative to annual SAV coverage for each Potomac River and Potomac Estuary segment. It is seen that although there is some correspondence in the inter-annual expansion or contraction of SAV coverage and compliance with Chesapeake Bay SAV habitat criteria, individual criteria provide neither necessary nor sufficient conditions to explain inter-annual dynamics of SAV coverage, especially in the Potomac Estuary.

The deepest sediments, the Donoho Creek Formation (545-475.7 ft), consist of 69.3 ft of muddy calcareous sand of marine origin. This formation is placed within the upper Campanian calcareous nannofossil Subzone CC 22c. The overlying Peedee Formation (475.7-367.1 ft) in the core consists of 108.6 ft of silty clay of marine origin. It is placed in upper Maastrichtian calcareous nannofossil Subzones CC 25b, CC 26a, and CC 26b. Combined fossil and paleomagnetic information indicates nearly continuous deposition. Foraminifers indicate an outer neritic paleobathymetric setting. The Rhems Formation sensu stricto (367.1-267.3 ft) consists of 99.8 ft of silty clay, muddy sand, and minor calcite-cemented, shelly sand of marine origin. It is apparently the product of rapid sediment accumulation during a short period of time in the early Paleocene (calcareous nannofossil Zone NP 1). The upper part of the Rhems Formation sensu Bybell and others (1998) (267.3-237.4 ft) consists of 29.9 ft of calcite-cemented muddy sand and burrowed fine sand of marine origin. It is placed in calcareous nannofossil Zone NP 4 and, because it shows normal polarity, likely represents the upper part of the lower Paleocene. This unit may be correlative with the lower part of the Lower Bridge Member of the Williamsburg Formation in its type area. The Lower Bridge Member of the Williamsburg Formation (237.4-125.0 ft) has an unconformable contact at 205.0 ft that divides the member into lower muddy sand beds and upper calcareous clay beds. Both are placed in the upper Paleocene calcareous nannofossil Zone NP 5. The Chicora Member of the Williamsburg Formation (125-51.5 ft) consists of 73.5 ft of muddy, shelly sand of marine origin. It is poorly dated but includes late Paleocene nannofossils (Zones NP 5 and NP 6). A mollusk-bryozoan limestone (51.5-42.0 ft) above the Chicora Member of the Williamsburg yields early Eocene calcareous nannofossils representing both Zone NP 9/10 and Zone NP 12, together with pollen and dinocysts that are younger.\r\n\r\nSediments of middle and late Eocene, Oligocene, Miocene, and Pliocene ages were not recovered in the Santee Coastal Reserve core. The upper 42.0 ft of sediments represent Quaternary deposits and are included in the Wando Formation (42.0-28.0 ft) and the informal Silver Bluff beds (28.0-0 ft).","language":"ENGLISH","doi":"10.3133/ofr99308B","usgsCitation":"Edwards, L.E., Gohn, G.S., Self-Trail J.M., Prowell, D., Bybell, L., Bardot, L.P., Firth, J.V., Huber, B., Frederiksen, N.O., and MacLeod, K., 1999, Physical stratigraphy, paleontology, and magnetostratigraphy of the USGS-Santee Coastal Reserve core (CHN-803), Charleston County, South Carolina: U.S. Geological Survey Open-File Report 99-308, One DS/HD 3 1/2 inch computer diskette. , https://doi.org/10.3133/ofr99308B.","productDescription":"One DS/HD 3 1/2 inch computer diskette.

A geographic information system was used to build three county-wide layers--soil permeability, land use/land cover, and land-surface slope. The harmonic mean permeability of soil layers was used to estimate a location's capacity to transmit water through the soil.\r\n\r\nValues for each of these three factors were categorized and ranked from 1 to 10 according to relative potential for contamination. Each factor was weighted to reflect its relative potential contribution to ground-water contamination, then the factors were combined to create a relative susceptibility index. The relative susceptibility index was categorized to reflect lowest, low, moderate, high, and highest potential for ground-water contamination.\r\n\r\nThe relative susceptibility index for about 12 percent of the area in Orange County was categorized as high or highest. The high and highest range areas have highly permeable soils, land cover or land-use activities that have a high contamination potential, and low to moderate slopes. Most of the county is within the moderate category of relative susceptibility to ground-water contamination. About 21 percent of the county is ranked as low or lowest relative susceptibility to ground-water contamination.","language":"ENGLISH","doi":"10.3133/ofr99179","usgsCitation":"Terziotti, S., and Eimers, J.L., 1999, Susceptibility of ground water to surface and shallow sources of contamination, Orange County, North Carolina: U.S. Geological Survey Open-File Report 99-179, 1 over-size sheet, scale 1:126,720 (1 inch = 2 miles). , https://doi.org/10.3133/ofr99179.","productDescription":"1 over-size sheet, scale 1:126,720 (1 inch = 2 miles).

These maps also indicate the presence of prominent features (geophysical lineaments) within and beneath the basin fill. Detailed gravity surveys were conducted in order to characterize the nature of the basin boundaries, delineate additional subsurface features, and evaluate their possible influence on the movement of ground-water. Geophysical modeling of gravity and aeromagnetic data indicates that many of the features may be related to processes of caldera formation. Collapse of the various calderas within the volcanic field resulted in dense basement rocks occurring at greater depths within caldera boundaries. Modeling indicates that collapse occurred along faults that are arcuate and steeply dipping. There are indications that the basement in the western Pahute Mesa - Oasis Valley region consists predominantly of granitic and/or fine-grained siliceous sedimentary rocks that may be less permeable to groundwater flow than the predominantly fractured carbonate rock basement to the east and southeast of the study area. The northeast-trending Thirsty Canyon lineament, expressed on gravity and basin thickness maps, separates dense volcanic rocks on the northwest from less dense intracaldera accumulations in the Silent Canyon and Timber Mountain caldera complexes. The source of the lineament is an approximately 2-km wide ring fracture system with step-like differential displacements, perhaps localized on a pre-existing northeast-trending Basin and Range fault. Due to vertical offsets, the Thirsty Canyon fault zone probably juxtaposes rock types of different permeability and, thus, it may act as a barrier to ground-water flow and deflect flow from Pahute Mesa along its flanks toward Oasis Valley. Within the Thirsty Canyon fault zone, highly fractured rocks may serve also as a conduit, depending upon the degree of alteration and its effect on porosity and permeability. In the Oasis Valley region, other structures that may influence ground-water flow include the western and southern boundaries of the Oasis Valley basin, where the basement abruptly shallows.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr99303","issn":"0566-8174","collaboration":"Prepared in cooperation with the U.S. Department of Energy Nevada Operations Office (Interagency Agreement DE-AI08-96NV11967)","usgsCitation":"Mankinen, E.A., Hildenbrand, T.G., Dixon, G.L., McKee, E.H., Fridrich, C.J., and Laczniak, R.J., 1999, Gravity and magnetic study of the Pahute Mesa and Oasis Valley region, Nye County, Nevada: U.S. Geological Survey Open-File Report 99-303, 58 p., https://doi.org/10.3133/ofr99303.","productDescription":"58 p.","additionalOnlineFiles":"N","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":51332,"rank":3,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0303/pdf/of99-303.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":153182,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1999/0303/report-thumb.jpg"},{"id":1241,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/0303/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Nevada","county":"Nye County","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -118.1972,35.9618 ], [ -118.1972,39.1634 ], [ -114.999,39.1634 ], [ -114.999,35.9618 ], [ -118.1972,35.9618 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd5f18e4b0b290850fc1db","contributors":{"authors":[{"text":"Mankinen, Edward A. 0000-0001-7496-2681 emank@usgs.gov","orcid":"https://orcid.org/0000-0001-7496-2681","contributorId":1054,"corporation":false,"usgs":true,"family":"Mankinen","given":"Edward","email":"emank@usgs.gov","middleInitial":"A.","affiliations":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"preferred":true,"id":185954,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Hildenbrand, Thomas G.","contributorId":61787,"corporation":false,"usgs":true,"family":"Hildenbrand","given":"Thomas","email":"","middleInitial":"G.","affiliations":[],"preferred":false,"id":185958,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dixon, Gary L.","contributorId":23571,"corporation":false,"usgs":true,"family":"Dixon","given":"Gary","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":185957,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"McKee, Edwin H. mckee@usgs.gov","contributorId":3728,"corporation":false,"usgs":true,"family":"McKee","given":"Edwin","email":"mckee@usgs.gov","middleInitial":"H.","affiliations":[],"preferred":true,"id":185956,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Fridrich, Christopher J. 0000-0003-2453-6478 fridrich@usgs.gov","orcid":"https://orcid.org/0000-0003-2453-6478","contributorId":1251,"corporation":false,"usgs":true,"family":"Fridrich","given":"Christopher","email":"fridrich@usgs.gov","middleInitial":"J.","affiliations":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"preferred":true,"id":185955,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Laczniak, Randell J.","contributorId":90687,"corporation":false,"usgs":true,"family":"Laczniak","given":"Randell","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":185959,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Despite its importance as a resource\r\nand as an example of a vapor-dominated reservoir,\r\nvery few complete geochemical analyses of the steam have\r\nbeen published (Allen and Day, 1927; Truesdell and others,\r\n1987). This report presents data from 90 steam, gas, and condensate\r\nsamples from wells in The Geysers geothermal field\r\nin northern California. Samples were collected between 1978\r\nand 1991. Well attributes include sampling date, well name,\r\nlocation, total depth, and the wellhead temperature and pressure\r\nat which the sample was collected. Geochemical characteristics\r\ninclude the steam/gas ratio, composition of noncondensable\r\ngas (relative proportions of CO2, H2S, He, H2,\r\nO2, Ar, N2, CH4, and NH3), and isotopic values for deltaD and\r\ndelta18O of H2O, delta13C of CO2, and delta34S of H2S. The compilation\r\nincludes 81 analyses from 74 different production wells, 9\r\nisotopic analyses of steam condensate pumped into injection\r\nwells, and 5 complete geochemical analyses on gases from\r\nsurface fumaroles and bubbling pools.\r\nMost samples were collected as saturated steam and\r\nplot along the liquid-water/steam boiling curve. Steam-togas\r\nratios are highest in the southeastern part of the geothermal\r\nfield and lowest in the northwest, consistent with other\r\nstudies. Wells in the Northwest Geysers are also enriched in\r\nN2/Ar, CO2 and CH4, deltaD, and delta18O. Well discharges from the\r\nSoutheast Geysers are high in steam/gas and have isotopic\r\ncompositions and N2/Ar ratios consistent with recharge by\r\nlocal meteoric waters. Samples from the Central Geysers\r\nshow characteristics found in both the Southeast and Northwest\r\nGeysers.\r\nGas and steam characteristics of well discharges from\r\nthe Northwest Geysers are consistent with input of components\r\nfrom a high-temperature reservoir containing carbonrich\r\ngases derived from the host Franciscan rocks. Throughout\r\nthe geothermal field, the carbon-isotopic composition of\r\nCO2 is consistent with derivation of carbon from Franciscan\r\nmetasedimentary rocks. NH3 concentrations are high in most\r\nGeysers well fluids, and are 2-3 orders of magnitude greater\r\nthan would be expected in a the gas phase exhibiting homogeneous\r\nequilibrium at normal reservoir temperatures and\r\npressures. Evidently, NH3 is flushed from the Franciscan host\r\nrocks at a rate that exceeds the reaction rate for NH3 breakdown.\r\nMany wells show clear influence by fluids from reinjection\r\nwells where steam condensate has been pumped\r\nback into the geothermal reservoir. Six wells were resampled\r\nover the time period of this study. One of these six wells was\r\nstrongly affected by a nearby injection well. Three of the six\r\nresampled wells showed some signs of decreasing liquid/\r\nsteam within the geothermal reservoir, consistent with 'drying\r\nout' of the reservoir due to steam withdrawal. However,\r\ntwo wells exhibited little change.\r\nAnalyses of gases from five surface manifestations (fumaroles\r\nand bubbling pools) are roughly similar to the deeper\r\ngeothermal samples in both chemical and isotopic composition,\r\nbut are lower in soluble gases that dissolve in groundwater\r\nduring transit toward the surface.","language":"ENGLISH","publisher":"U.S. Geological Survey","doi":"10.3133/ofr99304","issn":"0566-8174","usgsCitation":"Lowenstern, J.B., Janik, C.J., Fahlquist, L., and Johnson, L.S., 1999, Gas and Isotope Geochemistry of 81 Steam Samples from Wells in The Geysers Geothermal Field, Sonoma and Lake Counties, California (Version 1.0): U.S. Geological Survey Open-File Report 99-304, Report: 28 p.; Data Tables (xls), https://doi.org/10.3133/ofr99304.","productDescription":"Report: 28 p.; Data Tables (xls)","onlineOnly":"Y","additionalOnlineFiles":"Y","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":124928,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr_99_304.jpg"},{"id":13356,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/of99-304/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.91666666666667,38.700833333333335 ], [ -122.91666666666667,38.8675 ], [ -122.66666666666667,38.8675 ], [ -122.66666666666667,38.700833333333335 ], [ -122.91666666666667,38.700833333333335 ] ] ] } } ] }","edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b28e4b07f02db6b1349","contributors":{"authors":[{"text":"Lowenstern, Jacob B. 0000-0003-0464-7779 jlwnstrn@usgs.gov","orcid":"https://orcid.org/0000-0003-0464-7779","contributorId":2755,"corporation":false,"usgs":true,"family":"Lowenstern","given":"Jacob","email":"jlwnstrn@usgs.gov","middleInitial":"B.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":185685,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Janik, Cathy J.","contributorId":87090,"corporation":false,"usgs":true,"family":"Janik","given":"Cathy","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":185687,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fahlquist, Lynne","contributorId":8810,"corporation":false,"usgs":true,"family":"Fahlquist","given":"Lynne","affiliations":[],"preferred":false,"id":185686,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Johnson, Linda S.","contributorId":94334,"corporation":false,"usgs":true,"family":"Johnson","given":"Linda","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":185688,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

It has been postulated that the Cascadia subduction zone could be the source for a large thrust earthquake, possibly as large as M9.0. Large intraplate earthquakes from within the subducting Juan de Fuca plate beneath the Puget Sound region have accounted for most of the energy release in this century and future such large earthquakes are expected. Added to these possible hazards is clear evidence for strong crustal deformation events in the Puget Sound region near faults such as the Seattle fault, which passes through the southern Seattle metropolitan area. In order to understand the nature of these individual earthquake sources and their possible interrelationship, we have conducted an extensive seismotectonic study of the region. We have employed P-wave velocity models developed using local earthquake tomography as a key tool in this research. Other information utilized includes geological, paleoseismic, gravity, magnetic, magnetotelluric, deformation, seismicity, focal mechanism and geodetic data. Neotectonic concepts were tested and augmented through use of anelastic (creep) deformation models based on thin-plate, finite-element techniques developed by Peter Bird, UCLA. These programs model anelastic strain rate, stress, and velocity fields for given rheological parameters, variable crust and lithosphere thicknesses, heat flow, and elevation. Known faults in western Washington and the main Cascadia subduction thrust were incorporated in the modeling process.\r\n\r\nSignificant results from the velocity models include delineation of a previously studied arch in the subducting Juan de Fuca plate. The axis of the arch is oriented in the direction of current subduction and asymmetrically deformed due to the effects of a northern buttress mapped in the velocity models. This buttress occurs under the North Cascades region of Washington and under southern Vancouver Island. We find that regional faults zones such as the Devils Mt. and Darrington zones follow the margin of this buttress and the Olympic-Wallowa lineament forms its southern boundary east of the Puget Lowland. Thick, high-velocity, lower-crustal rocks are interpreted to be a mafic/ultramafic wedge occuring just above the subduction thrust. This mafic wedge appears to be jointly deformed with the arch, suggesting strong coupling between the subducting plate and upper plate crust in the Puget Sound region at depths >30 km. Such tectonic coupling is possible if brittle-ductile transition temperatures for mafic/ultramafic rocks on both sides of the thrust are assumed.\r\n\r\nThe deformation models show that dominant north-south compression in the coast ranges of Washington and Oregon is controlled by a highly mafic crust and low heat flow, allowing efficient transmission of margin-parallel shear from Pacific plate interaction with North America. Complex stress patterns which curve around the Puget Sound region require a concentration of northwest-directed shear in the North Cascades of Washington. The preferred model shows that greatest horizontal shortening occurs across the Devils Mt. fault zone and the east end of the Seattle fault.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr99311","issn":"0094-9140","usgsCitation":"Stanley, D., Villasenor, A.H., and Benz, H., 1999, Subduction zone and crustal dynamics of western Washington; a tectonic model for earthquake hazards evaluation: U.S. Geological Survey Open-File Report 99-311, 90 p., https://doi.org/10.3133/ofr99311.","productDescription":"90 p.","costCenters":[],"links":[{"id":155455,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1999/0311/report-thumb.jpg"},{"id":53648,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0311/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":1631,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/1999/ofr-99-0311/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699bf5","contributors":{"authors":[{"text":"Stanley, Dal","contributorId":71205,"corporation":false,"usgs":true,"family":"Stanley","given":"Dal","email":"","affiliations":[],"preferred":false,"id":192228,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Villasenor, Antonio H. 0000-0001-8592-4832","orcid":"https://orcid.org/0000-0001-8592-4832","contributorId":38186,"corporation":false,"usgs":true,"family":"Villasenor","given":"Antonio","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":192227,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Benz, Harley","contributorId":91460,"corporation":false,"usgs":true,"family":"Benz","given":"Harley","affiliations":[],"preferred":false,"id":192229,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The maps, called Flood Insurance Rate Maps, are used to determine flood insurance rates for homes, businesses, or other structures located in flood-prone areas. State and local governments also use these maps for help with, among other things, development planning and disaster mitigation. During the period October 1997 through December 1998, the initial phase of a hydraulic analysis project of the Boise River from Barber Dam to the Ada/Canyon County boundary, the U.S. Geological Survey collected stream channel cross-section data at 238 locations along the river and documented 108 elevation reference marks established for horizontal and vertical control. In the final phase of the project, the Survey will use these data to determine water-surface elevations for the 10-, 50-, 100-, and 500-year floods and to define floodway limits. The Federal Emergency Management Agency will use the results of this hydraulic analysis to update the 100- and 500-year flood boundaries and the floodway limits on their Flood Insurance Rate Maps.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr99211","issn":"0094-9140","collaboration":"Prepared in cooperation with Federal Emergency Management Agency, City of Boise, City of Garden City, City of Eagle, and Ada County","usgsCitation":"Hortness, J., and Werner, D.C., 1999, Stream channel cross sections for a reach of the Boise River in Ada County, Idaho: U.S. Geological Survey Open-File Report 99-211, Report: iv, 100 p.; Data files, https://doi.org/10.3133/ofr99211.","productDescription":"Report: iv, 100 p.; Data files","numberOfPages":"104","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":156210,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1999/0211/report-thumb.jpg"},{"id":52693,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0211/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":286888,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/1999/0211/data/"}],"country":"United States","state":"Idaho","county":"Ada","city":"Boise;Garden City;Eagle","otherGeospatial":"Barber Dam;Eagle Island","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -116.5141,43.3963 ], [ -116.5141,43.8075 ], [ -115.9742,43.8075 ], [ -115.9742,43.3963 ], [ -116.5141,43.3963 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b15e4b07f02db6a50eb","contributors":{"authors":[{"text":"Hortness, Jon 0000-0002-9809-2876 hortness@usgs.gov","orcid":"https://orcid.org/0000-0002-9809-2876","contributorId":3601,"corporation":false,"usgs":true,"family":"Hortness","given":"Jon","email":"hortness@usgs.gov","affiliations":[],"preferred":true,"id":190033,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Werner, Douglas C.","contributorId":51783,"corporation":false,"usgs":true,"family":"Werner","given":"Douglas","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":190034,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

In addition, the study will further the goals of the U.S. Geological Survey's (USGS) National Water Quality Assessment Program (NAWQA) by providing additional information on the occurrence and distribution of VOCs in ambient ground water beneath a large, highly urbanized part of the Nation. The study will proceed in two phases-a drinking-water assessment (phase 1) and an ambient ground-water assessment (phase 2). The drinking-water assessment will involve compilation, review, and analysis of available water- quality and ancillary data for approximately 20 percent of the community water systems in 12 States in the Northeast and Mid-Atlantic regions. This effort will summarize the occurrence and distribution of MTBE and other VOCs in drinking water supplied by 2,110 community water systems.

Estimates of hydraulic properties are needed to evaluate pathways for contaminants in ground water and to support evaluation and selection of remediation measures for contaminated ground water at this site. \r\n\r\n\r\nThe hydraulic conductivity of surficial materials, determined from specific-capacity tests, ranges from 17 to 78 feet per day for wells completed in coarse-grained glaciomarine sediments, and from about 0.1 to 1.Ofoot per day for wells completed in till. The transmissivity of fractured bedrock determined from specific-capacity tests and aquifer tests in wells completed in less than 200 feet of bedrock ranges from about 0.09 to 130 feet squared per day. Relatively high values of transmissivity at the south end of the study area appear to be associated with a high-angle fracture or fracture zone that hydraulically connects two wells completed in bedrock. Transmissivities at six low-yielding (less than 0.5 gallon per minute) wells, which appear to lie within a poorly transmissive block of the bedrock, are consistently in a range of about 0.09 to 0.5 foot squared per day.\r\n\r\n\r\nThe estimates of hydraulic conductivity and transmissivity in the southern half of the study area are supported by results of steady-state calibration of a numerical model and simulation of a 24-hour pumping test at a well completed in bedrock. Hydraulic conductivity values for the surficial aquifer used in the model were 30 feet per day for coarse-grained glaciomarine sediments, 0.001 to 0.01 foot per day for fine-grained glaciomarine sediments, and 0.1 to 0.5 foot per day for till. As part of model calibration, a relatively transmissive zone in the surficial aquifer was extended beyond the hypothesized extent of coarse-grained sediments eastward to the Dennys River.\r\n\r\n\r\nHydraulic conductivity values used for bedrock in the model ranged from 3x10-4 to 1.5 feet per day. The highest values were in the fracture zone that hydraulically connects two wells and apparently extends to the Dennys River. The transmissivity of bedrock used in the model ranged from 0.03 to 150 feet squared per day, with the majority of the bedrock transmissivities set at 0.3 foot squared per day. Numerical modeling results indicated that a very low ratio of vertical hydraulic conductivity to thickness (1x10-9 days-l) was required to simulate a persistent cone of depression near a residential well that lies in the previously identified poorly transmissive block of bedrock.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr99199","issn":"0094-9140","usgsCitation":"Lyford, F.P., Garabedian, S.P., and Hansen, B.P., 1999, Estimated hydraulic properties for the surficial- and bedrock-aquifer system, Meddybemps, Maine: U.S. Geological Survey Open-File Report 99-199, iv, 27 p., https://doi.org/10.3133/ofr99199.","productDescription":"iv, 27 p.","costCenters":[],"links":[{"id":157455,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":395187,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_19454.htm"},{"id":1780,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/ofr99199/","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Maine","city":"Meddybumps","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -67.3626708984375,\n              45.03371396774147\n            ],\n            [\n              -67.35189914703369,\n              45.03371396774147\n            ],\n            [\n              -67.35189914703369,\n              45.042174817839786\n            ],\n            [\n              -67.3626708984375,\n              45.042174817839786\n            ],\n            [\n              -67.3626708984375,\n              45.03371396774147\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ce4b07f02db5fcd6d","contributors":{"authors":[{"text":"Lyford, Forest P.","contributorId":43334,"corporation":false,"usgs":true,"family":"Lyford","given":"Forest","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":190699,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Garabedian, Stephen P.","contributorId":91090,"corporation":false,"usgs":true,"family":"Garabedian","given":"Stephen","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":190701,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hansen, Bruce P.","contributorId":90727,"corporation":false,"usgs":true,"family":"Hansen","given":"Bruce","email":"","middleInitial":"P.","affiliations":[],"preferred":false,"id":190700,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

At the long-term method detection level concentration, the risk of a false positive detection (analyte reported present at the long-term method detection level when not in sample) is no more than 1 percent. However, at the long-term method detection level, the risk of a false negative occurrence (analyte reported not present when present at the long-term method detection level concentration) is up to 50 percent. Because this false negative rate is too high for use as a default 'less than' reporting level, a more reliable laboratory reporting level is set at twice the determined long-term method detection level. For all methods, concentrations measured between the laboratory reporting level and the long-term method detection level will be reported as estimated concentrations. Non-detections will be censored to the laboratory reporting level. Adoption of the new reporting conventions requires a full understanding of how low-concentration data can be used and interpreted and places responsibility for using and presenting final data with the user rather than with the laboratory. Users must consider that (1) new laboratory reporting levels may differ from previously established minimum reporting levels, (2) long-term method detection levels and laboratory reporting levels may change over time, and (3) estimated concentrations are less certain than concentrations reported above the laboratory reporting level. The availability of uncensored but qualified low-concentration data for interpretation and statistical analysis is a substantial benefit to the user. A decision to censor data after they are reported from the laboratory may still be made by the user, if merited, on the basis of the intended use of the data.</p>","language":"English","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey ;\r\nInformation Services [distributor],","doi":"10.3133/ofr99193","usgsCitation":"Childress, C., Foreman, W., Connor, B.F., and Maloney, T.J., 1999, New reporting procedures based on long-term method detection levels and some considerations for interpretations of water-quality data provided by the U.S. Geological Survey National Water Quality Laboratory: U.S. Geological Survey Open-File Report 99-193, iv, 19 p., https://doi.org/10.3133/ofr99193.","productDescription":"iv, 19 p.","costCenters":[{"id":452,"text":"National Water Quality Laboratory","active":true,"usgs":true}],"links":[{"id":154299,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1999/0193/report-thumb.jpg"},{"id":51455,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/0193/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":1165,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://water.usgs.gov/owq/OFR_99-193/index.html","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4afee4b07f02db69752a","contributors":{"authors":[{"text":"Childress, Carolyn J.

Data from one well is incomplete because data collection was discontinued.\r\n\r\nChloride concentration in water from the Upper Floridan aquifer in most of coastal Georgia was within drinking-water standards established by the Georgia Department of Natural Resources and the U.S. Environmental Protection Agency. In the Savannah area, chloride concentration has not changed appreciably with time. However, chloride concentration in water from some wells that tap the Floridan aquifer system in the Brunswick area exceeds the drinking-water standards. \r\n","language":"ENGLISH","publisher":"U.S.

Ground-water quality data were compiled from Florida Department of Environmental Protection and surface-water quality data were compiled from U.S.Geological Survey files. Water-quality and water-level data were measured during two sample collection periods in October 1997 and March 1998 to determine water-quality and discharge rates in St. Joseph Bay under two sets of flow conditions. Measurements in the Bay included water level, temperature, pH, specific conductance, dissolved oxygen, and turbidity. \rMedian pH in water from the surficial, intermediate and Floridan aquifer systems ranged from 4.8 to 7.8, and median specific conductance values were less than 500 microsiemens per centimeter. Median nutrient concentrations-- nitrate plus nitrite, ammonia and phosphorus--in the three aquifers were less than 0.5 milligrams per liter. The median pH was 7.0 and the median specific conductance was 81 microsiemens per centimeter for two samples from the Chipola River distribution canal. Water level data were obtained for several wells near St. Joseph Bay but only two wells yielded sufficient data to plot hydrographs. \rMeasurements in St. Joseph Bay during the October and March collection periods were similar for pH and turbidity but differed for temperature, specific conductance and dissolved oxygen. The median temperature was 20.6 degrees Celsius in October and 15.4 degrees Celsius in March, median specific conductance was 39,500 microsiemens per centimeter in October and 43,300 microsiemens per centimeter in March, and median dissolved oxygen was 7.6 milligrams per liter in October and 8.3 milligrams per liter in March. The range in water levels over a tidal cycle in St. Joseph Bay on October 29, 1997 was about 1 foot. During a 24-hour tidal cycle on October 29, 1997, estimated hourly discharge varied from about -116,000 cubic feet per second (ft3/s) (into the Bay) to about +110,000 ft3/s (out of the Bay). During a 24-hour tidal cycle on March 3, 1998, the water level change was about 1.3 feet and estimated hourly discharge varied from about -132,000 ft3/s (into the Bay) to about +121,000 ft3/s (out of the Bay).","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr99190","usgsCitation":"Berndt, M.P., and Franklin, M., 1999, Water quality and discharge data for St. Joseph Bay, Florida, 1997-98: U.S. Geological Survey Open-File Report 99-190, 20 p., https://doi.org/10.3133/ofr99190.","productDescription":"20 p.","costCenters":[],"links":[{"id":162904,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":412821,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_19333.htm","linkFileType":{"id":5,"text":"html"}},{"id":3442,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/ofr99-190","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Florida","otherGeospatial":"St Joseph Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -85.21689363438676,\n              29.875514695904158\n            ],\n            [\n              -85.425,\n              29.875514695904158\n            ],\n            [\n              -85.425,\n              29.64957460709401\n            ],\n            [\n              -85.21689363438676,\n              29.64957460709401\n            ],\n            [\n              -85.21689363438676,\n              29.875514695904158\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a08e4b07f02db5fa33a","contributors":{"authors":[{"text":"Berndt, M.
