One-hundred-four VOCs were initially tested.\r\nOf these, 86 are suitable for determination by this method. Selected data are provided for\r\nthe 18 VOCs that were not included. This method also allows for the reporting of\r\nsemiquantitative results for tentatively identified VOCs not included in the list of method\r\ncompounds. Method detection limits, method performance data, preservation study\r\nresults, and blank results are presented.\r\nThe authors describe a procedure for reporting low-concentration detections at\r\nless than the reporting limit. The nondetection value (NDV) is introduced as a statistically\r\ndefined reporting limit designed to limit false positives and false negatives to less than 1\r\npercent. Nondetections of method compounds are reported as ?less than NDV.? Positive\r\ndetections measured at less than NDV are reported as estimated concentrations to alert the\r\ndata user to decreased confidence in accurate quantitation. Instructions are provided for\r\nanalysts to report data at less than the reporting limits. This method can support the use of\r\neither method reporting limits that censor detections at lower concentrations or the use of\r\nNDVs as reporting limits. The data-reporting strategy for providing analytical results at\r\nless than the reporting limit is a result of the increased need to identify the presence or\r\nabsence of environmental contaminants in water samples at increasingly lower\r\nconcentrations.\r\nLong-term method detection limits (LTMDLs) for 86 selected compounds range\r\nfrom 0.013 to 2.452 micrograms per liter (?g/L) and differ from standard method\r\ndetection limits (MDLs) in that the LTMDLs include the long-term variance of multiple\r\ninstruments, multiple operators, and multiple calibrations over a longer time. For these\r\nreasons, LTMDLs are expected to be slightly higher than standard MDLs. Recoveries for\r\nall of the VOCs tested ranged from 36 (tert-butyl formate) to 155 percent\r\n(pentachlorobenzene). The majority of the compounds ranged from 85 to 115 percent\r\nrecovery and had less than 5 percent relative standard deviation for concentrations spiked\r\nbetween 1 to 500 ?g/L in volatile blank-, surface-, and ground-water samples. Recoveries of 60 set spikes at low concentrations ranged from 70 to 114 percent (1,2,3-\r\ntrimethylbenzene and acetone). Recovery data were collected over 6 months with\r\nmultiple instruments, operators, and calibrations.\r\nIn this method, volatile organic compounds are extracted from a water sample by\r\nactively purging with helium. The VOCs are collected onto a sorbent trap, thermally\r\ndesorbed, separated by a Megabore gas chromatographic capillary column, and finally\r\ndetermined by a full-scan quadrupole mass spectrometer. Compound identification is\r\nconfirmed by the gas chromatographic retention time and by the resultant mass spectrum,\r\ntypically identified by three unique ions. An unknown compound detected in a sample\r\ncan be tentatively identified by comparing the unknown mass spectrum to reference\r\nspectra in the mass-spectra computer-data system library compiled by the National\r\nInstitute of Standards and Technology.","language":"English","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr97829","usgsCitation":"Connor, B.F., Rose, D.L., Noriega, M.C., Murtaugh, L.K., and Abney, S.R., 1998, Methods of analysis by the U.S. Geological Survey National Water Quality Laboratory-Determination of 86 volatile organic compounds in water by gas chromatography/mass spectrometry, including detections less than reporting limits: U.S. Geological Survey Open-File Report 97-829, viii, 78 p., https://doi.org/10.3133/ofr97829.","productDescription":"viii, 78 p.","costCenters":[{"id":452,"text":"National Water Quality Laboratory","active":true,"usgs":true}],"links":[{"id":153699,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1997/0829/report-thumb.jpg"},{"id":51418,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1997/0829/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":1283,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://nwql.usgs.gov/Public/pubs/OFR97-829/OFR97-829.html","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a54e4b07f02db62bb95","contributors":{"authors":[{"text":"Connor, Brooke F. bfconnor@usgs.gov","contributorId":3172,"corporation":false,"usgs":true,"family":"Connor","given":"Brooke","email":"bfconnor@usgs.gov","middleInitial":"F.","affiliations":[],"preferred":true,"id":186356,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Rose, Donna L. 0000-0003-1216-9914 dlrose@usgs.gov","orcid":"https://orcid.org/0000-0003-1216-9914","contributorId":4546,"corporation":false,"usgs":true,"family":"Rose","given":"Donna","email":"dlrose@usgs.gov","middleInitial":"L.","affiliations":[{"id":5046,"text":"Branch of Analytical Serv (NWQL)","active":true,"usgs":true}],"preferred":true,"id":186357,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Noriega, Mary C. mnoriega@usgs.gov","contributorId":2553,"corporation":false,"usgs":true,"family":"Noriega","given":"Mary","email":"mnoriega@usgs.gov","middleInitial":"C.","affiliations":[{"id":5046,"text":"Branch of Analytical Serv (NWQL)","active":true,"usgs":true}],"preferred":true,"id":186355,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Murtaugh, Lucinda K.","contributorId":14247,"corporation":false,"usgs":true,"family":"Murtaugh","given":"Lucinda","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":186358,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Abney, Sonja R.","contributorId":62992,"corporation":false,"usgs":true,"family":"Abney","given":"Sonja","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":186359,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

The estimated right-lateral slip is 0.8 to 1.7 m on the northern 30 km of the main trace of the Imperial fault, 4.8±0.2 m on a 10-km-long segment straddling the United States - Mexico border, and 1.3±0.4 m on a southern 25-km-long segment in Mexico.

The near-source flow rate is primarily a function of initial flow volume, which should be possible to estimate to an order of magnitude on the basis of geologic, geomorphic, and hydrologic factors at a particular volcano. Least-squares best fits to plots of flow-front travel time as a function of distance from source provide predictive second-degree polynomial equations with high coefficients of determination for four broad size classes of flow based on near-source flow rate: extremely large flows (>1 000 000 m<sup>3</sup>/s), very large flows (10 000–1 000 000 m<sup>3</sup>/s), large flows (1000–10 000 m<sup>3</sup>/s), and moderate flows (100–1000 m<sup>3</sup>/s). A strong nonlinear correlation that exists between initial total flow volume and flow rate for \"instantaneously\" generated debris flows can be used to estimate near-source flow rates in advance. Differences in geomorphic controlling factors among different flows in the data sets have relatively little effect on the strong nonlinear correlations between travel time and distance from source. Differences in flow type may be important, especially for extremely large flows, but this could not be evaluated here. At a given distance away from a volcano, travel times can vary by approximately an order of magnitude depending on flow rate. The method can provide emergency-management officials a means for estimating time windows for evacuation of communities located in hazard zones downstream from potentially hazardous volcanoes.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Bulletin of Volcanology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer-Verlag","doi":"10.1007/s004450050219","usgsCitation":"Pierson, T.C., 1998, An empirical method for estimating travel times for wet volcanic mass flows: Bulletin of Volcanology, v. 60, no. 2, p. 98-109, https://doi.org/10.1007/s004450050219.","productDescription":"12 p.","startPage":"98","endPage":"109","numberOfPages":"12","costCenters":[{"id":157,"text":"Cascades Volcano Observatory","active":false,"usgs":true}],"links":[{"id":282103,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282100,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/s004450050219"}],"volume":"60","issue":"2","noUsgsAuthors":false,"publicationDate":"1998-08-01","publicationStatus":"PW","scienceBaseUri":"53cd4c75e4b0b290850f1002","contributors":{"authors":[{"text":"Pierson, Thomas C. 0000-0001-9002-4273 tpierson@usgs.gov","orcid":"https://orcid.org/0000-0001-9002-4273","contributorId":2498,"corporation":false,"usgs":true,"family":"Pierson","given":"Thomas","email":"tpierson@usgs.gov","middleInitial":"C.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":490034,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Historical data for water and sediment collected from 1975 through 1986 were similar to data collected from 1987 through 1990. Some compounds were detected in concentrations that exceed U.S. Environmental Protection Agency water-quality criteria.\r\nResults from pesticide sampling at four stations in 1988 and 1989 identified several agricultural pesticides that were detected more frequently and at higher concentrations in urban areas than in agricultural areas. Results from herbicide sampling at 17 stations in the Kankakee and Iroquois River Basins in 1990 indicated that atrazine concentrations exceeded the U.S. Environmental Protection Agency's maximum contaminant level for drinking water during runoff periods.\r\n\r\nResults from sampling for volatile and semivolatile organic compounds in water indicate that, with one exception, all stations at which more than one compound was detected were within 2 miles downstream from the nearest point source. Detections at two stations in the Chicago urban area accounted for 37 percent of the total number of detections. Concentrations of tetrachloroethylene, trichloroethylene, and 1,2-dichlorethane from stations in the Des Plaines River Basin exceeded the U.S. Environmental Protection Agency's maximum contaminant level for drinking water in one and two samples from the two stations in the Chicago area.\r\n\r\nPhenols and pentachlorophenols were detected most frequently in the Des Plaines River Basin where point-source discharges were common. Phenol concentrations were significantly different among the Des Plaines, Kankakee, and Fox River Basins. Phenols and pentachlorophenols never exceeded the general use and secondary contact standards.\r\n\r\nResults from a 1989 synoptic survey of semivolatile organic compounds in sediment indicate that these compounds were detected most frequently at sites in the Chicago urban area. Of the 17 stations at which 10 or more compounds were detected, 14 were located in the Des Plaines River subbasin, and 1 was on the Illinois River mainstem. As was the case with organic compounds in water, each of these sites was located within 2 miles downstream from point sources.\r\n\r\nBiota samples were collected and analyzed for organochlorines and polynuclear aromatic hydrocarbons in 1989 and 1990. The most commonly detected compound in both years was p,p'-DDE. National Academy of Science recommendations for chlordane and dieldrin for protection of predators were exceeded in 19 and 10 samples, respectively, when the 1989 and 1990 data were combined. In the nine fish-fillet samples collected in 1989, concentrations exceeded U.S. Environmental Protection Agency fish-tissue criteria in nine fillets for p,p'-DDE and five fillets for dieldrin.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri964135","usgsCitation":"Sullivan, D.J., Stinson, T.W., Crawford, J.K., Schmidt, A.R., and Colman, J.A., 1998, Surface-water-quality assessment of the upper Illinois River Basin in Illinois, Indiana, and Wisconsin: Pesticides and other synthetic organic compounds in water, sediment, and biota, 1975-90: U.S. Geological Survey Water-Resources Investigations Report 96-4135, ix, 131 p., https://doi.org/10.3133/wri964135.","productDescription":"ix, 131 p.","costCenters":[],"links":[{"id":410424,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_48484.htm","linkFileType":{"id":5,"text":"html"}},{"id":54540,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1996/4135/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":158365,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1996/4135/report-thumb.jpg"}],"country":"United States","state":"Illinois, Indiana, Wisconsin","otherGeospatial":"upper Illinois River basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -87.50100801193956,\n              41.651204269025726\n            ],\n            [\n              -87.86903427371796,\n              42.67736509991755\n            ],\n            [\n              -87.85468280424294,\n              43.21643185455525\n            ],\n            [\n              -88.5468191414437,\n              42.97806865325791\n            ],\n            [\n              -88.7940388908309,\n              41.76665358974668\n            ],\n            [\n              -88.64362768300037,\n              40.67935213936329\n            ],\n            [\n              -87.9724865679459,\n              40.104537895285915\n            ],\n            [\n              -86.93471258293368,\n              40.035497013445195\n            ],\n            [\n              -86.43413199631502,\n              41.14711718277687\n            ],\n            [\n              -86.43401024073836,\n              41.648745486108396\n            ],\n            [\n              -86.70965405093068,\n              41.72392178190145\n            ],\n            [\n              -87.50100801193956,\n              41.651204269025726\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae4e4b07f02db689b0a","contributors":{"authors":[{"text":"Sullivan, Daniel J. 0000-0003-2705-3738 djsulliv@usgs.gov","orcid":"https://orcid.org/0000-0003-2705-3738","contributorId":1703,"corporation":false,"usgs":true,"family":"Sullivan","given":"Daniel","email":"djsulliv@usgs.gov","middleInitial":"J.","affiliations":[{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"preferred":false,"id":195093,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stinson, Troy W.","contributorId":33739,"corporation":false,"usgs":true,"family":"Stinson","given":"Troy","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":195095,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Crawford, J.

The primary objectives of this study are to (1) assess the degree to which such natural processes are attenuating chlorinated-hydrocarbon contamination in ground water, and (2) evaluate the effects of ground-water/surface-water interactions on natural-attenuation processes in the area of the former East and West Quartermasters Fueling Systems for Fort Wainwright, Alaska. The study will include investigations of the hydrologic, geochemical, and microbiological processes occurring at this site that influence the transport and fate of chlorinated hydrocarbons in ground water. To accomplish these objectives, a data-collection program has been initiated that includes measurements of water-table elevations and the stage of the Chena River; measurements of vertical temperature profiles within the subsurface; characterization of moisture distribution and movement in the unsaturated zone; collection of ground-water samples for determination of both organic and inorganic chemical constituents; and collection of ground-water samples for enumeration of microorganisms and determination of their potential to mineralize contaminants.\r\n\r\nWe will use results from the data-collection program described above to refine our conceptual model of hydrology and contaminant attenuation at this site. Measurements of water-table elevations and river stage will help us to understand the magnitude and direction of ground-water flow and how changes in the stage of the Chena River affect ground-water flow. Because ambient ground water and surface water typically have different temperature characteristics, temperature monitoring will likely provide further insight into ground-water/surface-water interactions in the subsurface. Characterization of the unsaturated zone will improve our understanding of interactions among ground water, the unsaturated zone, and the atmosphere. The interactions likely of importance to this study include the migration of water, dissolved contaminants, nutrients, and gases (oxygen, carbon dioxide, and methane) between the saturated and unsaturated zones. We will use the results of ground-water chemical analyses to determine the spatial and temporal distribution of (1) chlorinated-hydrocarbon contaminants and their degradation products, (2) oxidation-reduction indicators, (3) nutrients, and (4) major ground-water ions. These water-quality data will provide insight into ground-water flow directions, interactions between ground water and surface water, attenuation of contaminant concentrations caused by dispersion, and intrinsic microbiological processes. Microbiological analyses will indicate whether microorganisms at the site are capable of degrading the contaminants of interest, and will allow us to estimate their potential to attenuate existing contamination. Physical and chemical data interpreted as part of the analysis of ground water and surface water mixing will improve our understanding of the relationship between water quality and contaminant source mixing.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr98198","issn":"0094-9140","usgsCitation":"McCarthy, K.A., Lilly, M.R., Braddock, J.F., and Hinzman, L.D., 1998, Natural attenuation of chlorinated-hydrocarbon contamination at Fort Wainwright, Alaska: A hydrogeochemical and microbiological investigation workplan: U.S. Geological Survey Open-File Report 98-198, vii, 49 p., https://doi.org/10.3133/ofr98198.","productDescription":"vii, 49 p.","costCenters":[],"links":[{"id":152910,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1998/0198/report-thumb.jpg"},{"id":393124,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_19103.htm"},{"id":51452,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1998/0198/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Alaska","otherGeospatial":"Fort Wainwright","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -148.128662109375,\n              64.76241717518936\n            ],\n            [\n              -147.535400390625,\n              64.76241717518936\n            ],\n            [\n              -147.535400390625,\n              64.88509968914633\n            ],\n            [\n              -148.128662109375,\n              64.88509968914633\n            ],\n            [\n              -148.128662109375,\n              64.76241717518936\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b00e4b07f02db697f11","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":186524,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lilly, Michael R.","contributorId":65494,"corporation":false,"usgs":true,"family":"Lilly","given":"Michael","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":186525,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Braddock, Joan F.","contributorId":97934,"corporation":false,"usgs":true,"family":"Braddock","given":"Joan","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":186527,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hinzman, Larry D.","contributorId":97133,"corporation":false,"usgs":true,"family":"Hinzman","given":"Larry","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":186526,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

Data for 1997 included in this report are from continuous water-level records from 71 wells and chloride analyses from 14 wells.\r\n\r\nIn 1997, annual mean ground-water levels in Georgia ranged from 6.2 feet (ft) lower to 5.6 ft higher than in 1996. Of the 71 wells summarized in this report, 23 wells had annual mean water levels that were higher, 35 wells had annual mean water levels that were lower, and 11 wells had annual mean water levels that were about the same in 1997 as during 1996. Data for two wells are incomplete because data collection was discontinued at one well, and the equipment was vandalized at one well.\r\n\r\nRecord-low daily mean water levels were recorded in six wells tapping the Upper Floridan aquifer, one well tapping the Caliborne aquifer, two wells tapping the Clayton aquifer, and three wells tapping Cretaceous aquifers. These record lows were from 0.2 to 5.6 ft lower than previous record lows.\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 standard.\r\n\r\nGround-water-level and ground-water-quality data are essential for water assessment and management. Ground-water-level fluctuations and trends can be used to estimate changes in aquifer storage resulting from the effects of ground-water withdrawal and recharge from precipitation. These data can be used to address water-management needs and to evaluate the effects of management and conservation programs.\r\n\r\nAs part of the ground-water investigations conducted by the U.S. Geological Survey (USGS), in cooperation with the State of Georgia and city and county governments, a Statewide water-level- measurement program was started in 1938. Initially, this program consisted of an observation-well network in the coastal area of Georgia to monitor variations in ground- water storage and quality. Additional wells were later included in areas where data could be used to predict potential water-resource problems.\r\n\r\nDuring 1997, periodic water-level measurements were made in 67 wells, and continuous water-level measurements were obtained from 151 wells. Continuous water-level records were obtained using analog (pen and chart) recorders, digital recorders that record the water level at 30-minute or 60-minute intervals, and electronic data recorders that record the water level at 60-minute intervals. For wells having incomplete water-level record, water levels during periods of missing record may have been higher or lower than recorded water levels. Water samples collected from 23 wells during April and November 1997 were analyzed to determine chloride concentration in the Savannah and Brunswick areas.\r\n","language":"ENGLISH","publisher":"U.S.

Operable Unit 3 (OU3) occupies 134 acres on the eastern side of the Station and has been used for industrial and commercial purposes since World War II. Ground water contaminated by chlorinated organic compounds has been detected in the surficial aquifer at OU3. The U.S. Navy and U.S. Geological Survey (USGS) conducted a cooperative hydrologic study to evaluate the potential for ground water discharge to the neighboring St. Johns River. A ground-water flow model, previously developed for the area, was recalibrated for use in this study. \rAt the Station, the surficial aquifer is exposed at land surface and forms the uppermost permeable unit. The aquifer ranges in thickness from 30 to 100 feet and consists of unconsolidated silty sands interbedded with local beds of clay. The low-permeability clays of the Hawthorn Group form the base of the aquifer. \rThe USGS previously conducted a ground-water investigation at the Station that included the development and calibration of a 1-layer regional ground-water flow model. For this investigation, the regional model was recalibrated using additional data collected after the original calibration. The recalibrated model was then used to establish the boundaries for a smaller subregional model roughly centered on OU3. \rWithin the subregional model, the surficial aquifer is composed of distinct upper and intermediate layers. The upper layer extends from land surface to a depth of approximately 15 feet below sea level; the intermediate layer extends from the upper layer down to the top of the Hawthorn Group. In the northern and central parts of OU3, the upper and intermediate layers are separated by a low-permeability clay layer. Horizontal hydraulic conductivities in the upper layer, determined from aquifer tests, range from 0.19 to 3.8 feet per day. The horizontal hydraulic conductivity in the intermediate layer, determined from one aquifer test, is 20 feet per day. \rAn extensive stormwater drainage system is present at OU3 and the surrounding area. Some of the stormwater drains have been documented to be draining ground water from the upper layer of the surficial aquifer, whereas other drains are only suspected to be draining ground water. \rThe subregional model contained 78 rows and 148 columns of square model cells that were 100 feet on each side. Vertically, the surficial aquifer was divided into two layers; layer 1 represented the upper layer and layer 2 represented the intermediate layer. Steady-state ground-water flow conditions were assumed. The model was calibrated to head data collected on October 29 and 30, 1996. After calibration, the model matched all 67 measured heads to within the calibration criterion of 1 foot; and 48 of 67 simulated heads (72 percent) were within 0.5 foot. \rModel simulated recharge rates ranged from 0.4 inch per year in areas that were largely paved to 13.0 inches per year in irrigated areas. Simulated hydraulic conductivities in the upper layer at OU3 ranged from 0.5 foot per day in the north to 1.0 foot per day in the south. Simulated vertical leakance between the upper and intermediate layers ranged from 1.0x10-6 per day in an area with low-permeability clays to 4.3x10-2 per day in an area that had been dredged. Simulated transmissivities in the intermediate layer ranged from 25 feet squared per day in an area of low-permeability channel-fill deposits to a high of 1,200 feet squared per day in areas covering most of OU3. Simulated riverbed conductances ranged from 4 to 60 feet squared per day and simulated bottom conductances of leaking stormwater drains ranged from 5 to 20 feet squared per day. \rThe direction and velocity of ground-water flow was determined using particle-tracking techniques. Ground-water flow in the upper layer was generally eastward toward the St. Johns River.

The sites were divided into five groups on the basis of physiographic region and land use. Ten compounds were detected in tissue, and 16 compounds were detected in bed sediment. The most frequently detected compound in both media was p,p'-DDE. Concentrations of total DDT (sum of o,p'- and p,p'-forms of DDD, DDE, and DDT) were statistically different among groups of sites for tissue and sediment (Kruskal-Wallis, P < 0.05). Concentrations in both media were highest in streams draining the west side of the valley. Concentrations of total DDT in tissue were significantly correlated with specific conductance, pH, and total alkalinity (P < 0.05), which are indicators of the proportion of irrigation-return flows in stream discharge. Concentrations in sediment on a dry-weight basis were not correlated with these water-quality parameters, but total-organic- carbon (TOC) normalized concentrations were significantly correlated with specific conductance and pH (P < 0.05). Regressions of the concentration of total DDT in tissue as a function of total DDT in bed sediment were significant and explained as much as 76 percent of the variance in the data. The concentration of total DDT in sediment may be related to mechanisms of soil transport to surface water with bioavailability of compounds related to the concentration of TOC in sediment.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nBranch of Information Services [distributor],","doi":"10.3133/ofr98171","issn":"0094-9140","usgsCitation":"Brown, L.R., 1998, Concentrations of chlorinated organic compounds in biota and bed sediment in streams of the lower San Joaquin River drainage, California: U.S. Geological Survey Open-File Report 98-171, vi, 22 p. :ill., maps ;28 cm., https://doi.org/10.3133/ofr98171.","productDescription":"vi, 22 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":155329,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1998/0171/report-thumb.jpg"},{"id":52064,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1998/0171/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db699d2e","contributors":{"authors":[{"text":"Brown, Larry R. 0000-0001-6702-4531 lrbrown@usgs.gov","orcid":"https://orcid.org/0000-0001-6702-4531","contributorId":1717,"corporation":false,"usgs":true,"family":"Brown","given":"Larry","email":"lrbrown@usgs.gov","middleInitial":"R.","affiliations":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"preferred":true,"id":188519,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The approach used to meet the first objective is to develop a digital ground-water flow model. The model will be cali brated, in part, by comparing simulated and esti mated predevelopment discharge from the aquifer to streams and cross-boundary flow. This report presents the estimated predevelopment discharge to streams from the High Plains aquifer.\r\nStreamflow data were the primary source of information used to estimate predevelopment dis charge from the High Plains aquifer. Data from 30 streamflow stations between the Arkansas and Canadian Rivers were considered in the analysis, and winter low-flow frequencies for 7-, 14-, and 30-day periods were determined for 25 stations. The 14-day low flow with a recurrence interval of 2 years was the primary value used to estimate pre development discharge from the aquifer.\r\n\r\nThe streams that drain the eastern part of the High Plains aquifer in Kansas (generally east of 99.5 longitude) are estimated to have had large predevelopment discharge from the aquifer, and most of them received discharge from near their headwaters. For streams with more than one streamflow gage, the upper perennial reaches appeared to have gained more discharge from the aquifer than the lower reaches. The total predevel opment discharge from the aquifer in this area to several streams is estimated to have been about 312 cubic feet per second, not including discharge that probably went directly to the Arkansas River. The Cimarron River and its tributaries are estimated to have gained about 78 cubic feet per second, but nearly one-half that amount was lost in the lower reaches of the river. The cause of the loss in the lower reaches is unknown. The Beaver River and its tributaries are estimated to have gained a net of about 10 cubic feet per second above Wolf Creek with the upper reaches gaining more than the lower reaches. Wolf Creek is estimated to have gained 30 cubic feet per second over its total length.","language":"ENGLISH","publisher":"U.S. Geological Survey ;\r\nBranch of Information Services [distributor],","doi":"10.3133/wri974287","usgsCitation":"Luckey, R.R., and Becker, M., 1998, Estimated predevelopment discharge to streams from the High Plains Aquifer in northwestern Oklahoma, southwestern Kansas, and northwestern Texas: U.S. Geological Survey Water-Resources Investigations Report 97-4287, iv, 28 p. :ill., maps ;28 cm., https://doi.org/10.3133/wri974287.","productDescription":"iv, 28 p. :ill., maps ;28 cm.","costCenters":[],"links":[{"id":124775,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1997/4287/report-thumb.jpg"},{"id":57276,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1997/4287/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a81e4b07f02db64a130","contributors":{"authors":[{"text":"Luckey, R.

The most frequently detected compounds were the herbicides alachlor, atrazine, cyanazine, and metolachlor, and in 1994, its first year of registration, acetochlor. Peak concentrations of most herbicides in rainfall occurred shortly after their application periods in the spring. Peak concentrations of most of the insecticides occurred later in the summer.</p>\n<p>The majority of the wet depositional flux of pesticides occurred between early May and October. The annual wet depositional flux of pesticides is 5 orders of magnitude less than is the \"annual flux\" normally applied on an agricultural field, although some of the pesticides in rain are deposited in areas far removed from agricultural fields. The annual variability in pesticide deposition can be explained by year-to-year differences in climate and pesticide use patterns. The one sampling site (Lamberton) that was in an area dominated by row crop agriculture showed a significantly greater annual flux than the other four sampling sites that were in areas of either urbanization or less intensive agricultural. Regional deposition, away from a local source, can be inferred from these four sites because they have annual pesticide fluxes that are very similar for any given year. The observation of agricultural pesticides (not registered for home and garden use) in rain and storm runoff in the urban area indicates their transport from areas of agricultural use. Urban areas may be the best locations for assessing changes in regional use and deposition of agricultural pesticides.</p>\n<p>The pesticide fluxes in the streams out of the small three watersheds was compared to the pesticide flux into the watersheds in rain. The data indicate that flux into the watersheds from the rain is generally much greater than the flux from the watersheds in the streams. Therefore, a large fraction of the pesticides deposited in rain is retained within the watersheds.

The goal of the exercise was to provide managers with maps that could illustrate probable shifts in vegetation, net primary production (NPP), and hydrologic responses associated with two selected climatic scenarios. The climatic scenarios were (a) a recent 12-yr record of weather data, and (b) a reconstituted set that sequentially introduced in repeated 3-yr intervals wetter–cooler, drier–warmer, and typical conditions. To extrapolate the implications of changes in ecosystem processes and resulting growth and distribution of vegetation and snowpack, the model incorporated geographic data. With underlying digital elevation maps, soil depth and texture, extrapolated climate, and current information on vegetation types and satellite-derived estimates of leaf area indices, simulations were extended to envision how the park might look after 120 yr. The predictions of change included underlying processes affecting the availability of water and nitrogen. Considerable field data were acquired to compare with model predictions under current climatic conditions. In general, the integrated landscape models of ecosystem processes had good agreement with measured NPP, snowpack, and streamflow, but the exercise revealed the difficulty and necessity of averaging point measurements across landscapes to achieve comparable results with modeled values. Under the extremely variable climate scenario significant changes in vegetation composition and growth as well as hydrologic responses were predicted across the park. In particular, a general rise in both the upper and lower limits of treeline was predicted. These shifts would probably occur along with a variety of disturbances (fire, insect, and disease outbreaks) as predictions of physiological stress (water, nutrients, light) altered competitive relations and hydrologic responses. The use of integrated landscape models applied in this exercise should provide managers with insights into the underlying processes important in maintaining community structure, and at the same time, locate where changes on the landscape are most likely to occur.</span></p>","language":"English","publisher":"Ecological Society of

To aid in the identification of methods suitable for this purpose, the U.S. EPA, the Chemical Manufacturers Association, and the World Wildlife Fund sponsored several workshops, including the present one, which dealt with wildlife species. This workshop was convened with 30 international scientists representing multiple disciplines in March 1997 in Kansas City, Missouri, USA. Participants at the meeting identified methods in terms of their ability to indicate (anti-) estrogenic/androgenic effects, particularly in the context of developmental and reproductive processes. Data derived from structure-activity relationship models and in vitro test systems, although useful in certain contexts, cannot at present replace in vivo tests as the sole basis for screening. A consensus was reached that existing mammalian test methods (e.g., with rats or mice) generally are suitable as screens for assessing potential (anti-) estrogenic/ androgenic effects in mammalian wildlife. However, due to factors such as among-class variation in receptor structure and endocrine function, it is uncertain if these mammalian assays would be of broad utility as screens for other classes of vertebrate wildlife. Existing full and partial life-cycle tests with some avian and fish species could successfully identify chemicals causing endocrine disruption; however, these long-term tests are not suitable for routine screening. However, a number of short-term tests with species from these two classes exist that could serve as effective screening tools for chemicals inducing (anti-) estrogenic/androgenic effects. Existing methods suitable for identifying chemicals with these mechanisms of action in reptiles and amphibians are limited, but in the future, tests with species from these classes may prove highly effective as screens. In the case of invertebrate species, too little is known at present about the biological role of estrogens and androgens in reproduction and development to recommend specific assays.</span></p>","language":"English","publisher":"Society of Environmental Toxicology and Chemistry","doi":"10.1002/etc.5620170110","usgsCitation":"Ankley, G., Mihaich, E., Stahl, R.G., Tillitt,

The author lists the areas by continent of the world's grasslands as depicted in four global land cover data sets. Grasslands, by definition, include regions where the dominant vegetative cover is herbaceous. Functionally, they include managed rangelands and pastures. These ecosystems have been experiencing alterations such as changes in productivity, desertification, influx of exotic species, and conversion to agriculture. Some of the largest temperate grassland areas have been subjected to broad-scale land use conversion. For example, the central plains of North America have been largely converted into the \"world's most productive dryland wheat region\". Grassland regions exhibit sensitivity to changes in environmental conditions. For example, the boundaries between grasslands and other vegetation types, as well as between different grassland types, on the North American plains are subject to change based on factors such as available exhibit sensitivity to changes in moisture, precipitation, length of growing season, or maximum temperature within the growing season. In global climate change scenarios, there are predicted changes for such environmental factors, however the magnitude and location for the changes are as yet unclear. In some cases, climate changes coupled with the human-induced changes of grasslands are expected to intensify such processes as desertification or degradation.</span></p>","conferenceTitle":"IGARSS '98.

Isotopes are viewed as tools for testing rather than developing hypotheses, particularly in studies operating under tight budgetary constraints. Water isotopes are very useful tools for determining water sources in catchments. Chemical tracers are very useful for understanding the reactions along flowpaths. The potential application of Fe isotopes to catchment studies lies in the assumption that Fe mobilized inorganically from minerals under either reducing or low-pH conditions will have a different isotopic composition than microbially-reduced Fe. To the extent that certain zones or flowpaths in the catchment can be characterized by microbial cycling of labile Fe, the Fe isotopes may provide an effective tracer of contributions from these pathways. The solute isotopes, for example, strontium, carbon, and lead are as yet under-utilized in catchment research compared to the water isotopes.</span></p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Isotope tracers in catchment hydrology","language":"English","publisher":"Elsevier","doi":"10.1016/B978-0-444-81546-0.50025-2","isbn":"978-0-08-092915-6","usgsCitation":"Bullen, T.D., and Kendall, C., 1998, Tracing of weathering reactions and water flowpaths: A multi-isotope approach, chap. 18 <i>of</i> Isotope tracers in catchment hydrology, p. 611-646, https://doi.org/10.1016/B978-0-444-81546-0.50025-2.","productDescription":"36 p.","startPage":"611","endPage":"646","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":337551,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"58c9012ae4b0849ce97abd2d","contributors":{"authors":[{"text":"Bullen, Tomas D.","contributorId":64792,"corporation":false,"usgs":true,"family":"Bullen","given":"Tomas","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":684335,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kendall, Carol 0000-0002-0247-3405 ckendall@usgs.gov","orcid":"https://orcid.org/0000-0002-0247-3405","contributorId":1462,"corporation":false,"usgs":true,"family":"Kendall","given":"Carol","email":"ckendall@usgs.gov","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":684336,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}
