Flow measurements were made and water samples were collected at the inlet to, outlet from, and bypass around the treatment chamber of the device that was installed to collect the runoff from a city maintenance yard.</p>\n<p>About 90 percent of the runoff water from the 4.3-acre basin was treated by the unit. The remaining 10 percent bypassed the treatment chamber when the flow rate reached approximately 500 gallons per minute.</p>\n<p>A 24-percent difference between the estimated amount (405 kilograms) and the actual amount (536 kilograms) of retained material in the treatment chamber may be attributed to bedload material that the automatic samplers could not effectively collect. Assuming this, 8 percent of the total mass in the untreated runoff water was estimated as the unsampled bedload.</p>\n<p>On the basis of water-sample data collected over the course of the study, the suspended solids removal efficiency of treatment chamber was about 25 percent, and the efficiency of the unit as a whole was 21 percent. If the unsampled bedload material was accounted for, the treatment-chamber efficiency was 33 percent.</p>\n<p>About 19 percent of the total phosphorus was removed from the water that passed through the treatment chamber and 17 percent was removed by the unit as a whole. Total polycyclic aromatic hydrocarbon (PAH) loads were reduced about 39 percent by the treatment chamber and 34 percent by the unit as a whole; these were some of the most effectively removed constituents. Total metals were reduced about 20 to 30 percent by both the treatment chamber and the unit as a whole. In general, dissolved constituents were unaffected by the unit.</p>\n<p>The material retained in the treatment chamber had high concentrations of lead and PAH and may be subject to special disposal restrictions based on those concentrations and the presence of benzo(a)anthracene. The chemical makeup of the retained material in other similar stormwater treatment units will probably vary depending on the land use and activities in the drainage basin.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri994195","collaboration":"Prepared in cooperation with the City of Madison, and the Wisconsin Department of Natural Resources","usgsCitation":"Waschbusch, R.J., 1999, Evaluation of the effectiveness of an urban stormwater treatment unit in Madison, Wisconsin, 1996-97: U.S. Geological Survey Water-Resources Investigations Report 99-4195, v, 49 p., https://doi.org/10.3133/wri994195.","productDescription":"v, 49 p.","numberOfPages":"60","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"links":[{"id":59165,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1999/4195/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":2510,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri994195","linkFileType":{"id":5,"text":"html"}},{"id":124934,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1999/4195/report-thumb.jpg"}],"country":"United States","state":"Wisconsin","county":"Dane County","city":"Madison","otherGeospatial":"Lake Mendota, Lake Menona","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -89.55917358398438,\n              43.01820348594956\n            ],\n            [\n              -89.55917358398438,\n              43.177141346631714\n            ],\n            [\n              -89.21241760253906,\n              43.177141346631714\n            ],\n            [\n              -89.21241760253906,\n              43.01820348594956\n            ],\n            [\n              -89.55917358398438,\n              43.01820348594956\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f3e4b07f02db5ef3fd","contributors":{"authors":[{"text":"Waschbusch, Robert J. 0000-0002-4069-0267 rjwaschb@usgs.gov","orcid":"https://orcid.org/0000-0002-4069-0267","contributorId":3447,"corporation":false,"usgs":true,"family":"Waschbusch","given":"Robert","email":"rjwaschb@usgs.gov","middleInitial":"J.","affiliations":[{"id":677,"text":"Wisconsin Water Science Center","active":true,"usgs":true}],"preferred":true,"id":203167,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

This study was designed to increase the current understanding of the ground-water resource, and to better characterize the distribution of naturally occurring poor quality ground water in the basin. Essential components of the study of the physical ground-water resource are the development of a quantitative understanding of regional ground-water availability and flow, and of ground-water/surface-water interactions. Of paramount interest in the characterization of naturally occurring poor-quality ground water in the Willamette Basin is the distribution of arsenic in ground water, the subject of this report.</p>\n<p>Arsenic contaminates many regional aquifer systems worldwide (Cantor, 1996; Thornton, 1996), and arsenic commonly is detected in ground water of the Willamette Basin at concentrations exceeding the U.S. Environmental Protection Agency (USEPA) current drinking water Maximum Contaminant Level (MCL) of 50 &micro;g/L (micrograms per liter) (U.S. Environmental Protection Agency, 1996). Arsenic is associated with a number of adverse effects on human health. The USEPA considers arsenic to be a human carcinogen (U.S. Environmental Protection Agency, 1996). Examples of other adverse health effects attributed to consumption of arsenic range from weakness and abdominal pain to neurological and cardiovascular problems. A review of health effects associated with consumption of arsenic is given in a report by World Health Organization (1996).</p>\n<p>&nbsp;</p>\n<p>&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Portland, OR","doi":"10.3133/wri984205","collaboration":"Prepared in cooperation with Oregon Water Resources Department","usgsCitation":"Hinkle, S.R., and Polette, D.J., 1999, Arsenic in ground water of the Willamette Basin, Oregon: U.S. Geological Survey Water-Resources Investigations Report 98-4205, Report: iv, 28 p.; 1 Plate: 24.01 x 35.00 inches, https://doi.org/10.3133/wri984205.","productDescription":"Report: iv, 28 p.; 1 Plate: 24.01 x 35.00 inches","numberOfPages":"34","onlineOnly":"N","additionalOnlineFiles":"Y","costCenters":[{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true}],"links":[{"id":158846,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri984205.PNG"},{"id":311175,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1998/4205/report.pdf","text":"Report","size":"1.17 MB","linkFileType":{"id":1,"text":"pdf"},"description":"Report"}],"country":"United States","state":"Oregon","otherGeospatial":"Willamette River","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -123.49731445312499,\n              42.99661231842139\n            ],\n            [\n              -123.49731445312499,\n              45.89000815866184\n            ],\n            [\n              -120.1904296875,\n              45.89000815866184\n            ],\n            [\n              -120.1904296875,\n              42.99661231842139\n            ],\n            [\n              -123.49731445312499,\n              42.99661231842139\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abce4b07f02db672d89","contributors":{"authors":[{"text":"Hinkle, Stephen R. srhinkle@usgs.gov","contributorId":1171,"corporation":false,"usgs":true,"family":"Hinkle","given":"Stephen","email":"srhinkle@usgs.gov","middleInitial":"R.","affiliations":[{"id":518,"text":"Oregon Water Science Center","active":true,"usgs":true}],"preferred":true,"id":198558,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Polette, Danial J. dpolette@usgs.gov","contributorId":1100,"corporation":false,"usgs":true,"family":"Polette","given":"Danial","email":"dpolette@usgs.gov","middleInitial":"J.","affiliations":[],"preferred":true,"id":198557,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Development was represented in the model in two ways: (1) as a pervious area (open and residential land) that simulates the hydrologic response from mixed pervious and impervious areas that drain to pervious areas, or (2) as an impervious area that drains to channels. Simulations indicate that peak discharges for 30 non-winter storms in 1995-96 would increase by an average of 10 to 37 percent in response to a 10- to 100-percent buildup of developable land represented as open/residential land and by 40 to 68 percent in response to 10 to 100 percent buildup of developable area represented as impervious area. A 10 to 100 percent buildup of developable area represents an impervious area of about 1 to 7 percent of the watershed. A log Pearson Type-III analysis of peak annual discharge for October 1989 through September 1996 for simulations with full development represented as impervious area indicates that stormflows that formerly occurred once every 2 years on average will occur once every 1.5 years, and stormflows that formerly occurred once every 5 years will occur once every 3.3 years.</p><p>Simulations of a hypothetical 147-acre residential development in the lower part of the watershed with and without stormwater detention indicate that detention basins could cause either increase or decrease downstream flooding of Ninemile Creek at Camillus, depending on the basin.s available storage relative to its inflows and, hence, the timing of its peak outflow in relation to that of the peak discharge in Ninemile Creek; and the degree of flow retention by wetlands and other channel storage that affect the timing of peak discharges. Design and management of detention basins in the watershed will require analysis of each basin.s hydraulic characteristics and location relative to Ninemile Creek to predict their effect on downstream flooding.

During March 10 to 13, 1997, the U.S. Geological Survey conducted a bathymetric survey of Lago Yahuecas to determine the amount of sediment deposited and sedimentation rate in the reservoir. Also, reservoir sediments were cored and sampled to determine the dry bulk density. Over the last 41 years, the storage capacity of the reservoir has been reduced by approximately 81 percent from 1.76 million cubic meters in 1956 to 0.33 million cubic meters in 1997.

The increase in water supply to meet future demands is expected to be accommodated by supplementing surface-water inflows to Lake Houston. The Trinity River is considered a potential source for interbasin transfer of water to Lake Houston. Before beginning to supplement inflows, the City needs to better understand the potential effects on Lake Houston water quality from streams that flow into or might contribute water to Lake Houston. During 1983&ndash;90, the USGS collected 3,727 water-quality samples from 27 sites in Lake Houston, 6 of the 7 main tributaries to the lake, and the Trinity River at Romayor.</p>\n<p>Longitudinal profiles of water temperature, dissolved oxygen, specific conductance, pH, and nutrients from the dam to the East and West Forks of Lake Houston constructed for a winter day and a summer day indicate that in general the lake water is mixed in the winter and stratified in the summer.</p>\n<p>The results of Mann-Whitney rank-sum tests to determine whether there were significant differences between summer and non-summer field measurements, 5-day biological oxygen demand, bacteria, physical and aesthetic properties, nutrients, organic carbon, chlorophyll a, and trace elements in the lake nearest the dam, the East Fork of the lake, and the West Fork of the lake at the same relative depth showed significant differences between summer and non-summer samples for at least one of the three locations at the same relative depth for all 15 properties and constituents tested except specific conductance. The test results indicate that in general Lake Houston is well mixed in the non-summer period and stratified with respect to selected properties and constituents in the summer.</p>\n<p>The results of rank-sum tests to determine whether there were significant differences between field measurements, 5-day biological oxygen demand, physical and aesthetic properties, nutrients, organic carbon, and chlorophyll a in the lake nearest the dam, the East Fork of the lake, and the West Fork of the lake for samples collected during the same season at the same relative depth showed that significant differences were common; generally, the West Fork had the largest median concentrations among the three locations. The tests comparing trace element concentrations between the lake nearest the dam and the East Fork showed mixed results&mdash;large median dissolved manganese concentrations in lake bottom samples in the summer and in East Fork near-surface samples in the non-summer period.</p>\n<p>The results of rank-sum tests comparing selected properties, 5-day biological oxygen demand, bacteria, nutrients, and total organic carbon in the eastern tributaries with those in the western tributaries, in the eastern tributaries with those in the Trinity River, and in the western tributaries with those in the Trinity River during the same season (summer or non-summer) at the same relative streamflow (low-medium or high) showed that significant differences were more common than not. In the comparisons of the eastern tributaries with&nbsp;the western tributaries that resulted in significant differences, medians of the western tributaries were larger for all properties and constituents except total organic carbon; in the comparisons of the eastern tributaries with the Trinity River that resulted in significant differences, medians were larger for the Trinity River in about 60 percent of the tests; and in the comparisons of the western tributaries with the Trinity River that resulted in significant differences, medians were larger for the western tributaries in about 60 percent of the tests.</p>\n<p>In the tests comparing trace elements between the eastern and western tributaries during the same season at the same relative streamflow, five of the eight tests showed no significant differences; between the eastern tributaries and the Trinity River, all eight tests showed significant differences, with eastern tributary medians larger in all tests; and between the western tributaries and the Trinity River, seven of the eight tests showed significant differences, with western tributary medians larger in all seven tests.</p>\n<p>The tests comparing selected properties, 5-day biological oxygen demand, nutrients, and total organic carbon between the eastern tributaries and the East Fork of Lake Houston, between the western tributaries and the West Fork of Lake Houston, and between the Trinity River and the lake nearest the dam, the East Fork, and the West Fork during the same season (summer or nonsummer) yielded significant differences in about 60 percent of the tests.

Over a 7-week period, splits of filtered- and whole-water samples from 15 stations in the continental United States were preserved at collection sites with sulfuric acid (U.S. Environmental Protection Agency protocol), mercury (II) chloride (former U.S. Geological Survey protocol), and ASTM (American Society for Testing and Materials) Type I deionized water (control) and then shipped by overnight express to the USGS National Water Quality Laboratory (NWQL). At the NWQL, the eight nutrient species were determined in splits from each of the 15 stations, typically, within 24 hours of collection and at intervals of 3, 7, 14, 22, and 35 days thereafter. Ammonium, nitrate plus nitrite, nitrite, and orthophosphate were determined only in filtered-water splits. Kjeldahl nitrogen and phosphorus were determined in both filtered-water and whole-water splits.\nData on which this report is based, including nutrient concentrations in synthetic reference samples determined concurrently with those in real samples, are extensive (greater than 20,000 determinations) and have been published separately. In addition to confirming the well-documented instability of nitrite in acidified samples, this study also demonstrates that when biota are removed from samples at collection sites by 0.45-micrometer membrane filtration, subsequent preservation with sulfuric acid or mercury (II) provides no statistically significant improvement in nutrient concentration stability during storage at 4 degrees Celsius for 30 days. Biocide preservation had no statistically significant effect on the 30-day stability of phosphorus concentrations in whole-water splits from any of the 15 stations, but did stabilize Kjeldahl nitrogen concentrations in whole-water splits from three data-collection stations where ammonium accounted for at least half of the measured Kjeldahl nitrogen.","language":"English","publisher":"U.S. Dept. of the Interior, U.S. Geological Survey :Branch of Information Services [distributor],","doi":"10.3133/wri984118","usgsCitation":"Patton, C.J., and Gilroy, E.J., 1999, US Geological Survey nutrient preservation experiment: Experimental design, statistical analysis, and interpretation of analytical results: U.S. Geological Survey Water-Resources Investigations Report 98-4118, ix, 73 p., https://doi.org/10.3133/wri984118.","productDescription":"ix, 73 p.","costCenters":[{"id":452,"text":"National Water Quality Laboratory","active":true,"usgs":true}],"links":[{"id":159442,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1998/4118/report-thumb.jpg"},{"id":278848,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1998/4118/report.pdf"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a29e4b07f02db611a3e","contributors":{"authors":[{"text":"Patton, Charles J. cjpatton@usgs.gov","contributorId":809,"corporation":false,"usgs":true,"family":"Patton","given":"Charles","email":"cjpatton@usgs.gov","middleInitial":"J.","affiliations":[],"preferred":true,"id":200903,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gilroy, Edward J.","contributorId":50524,"corporation":false,"usgs":true,"family":"Gilroy","given":"Edward","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":200904,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Results indicate that the accumulation of post-impoundment sediment is restricted to the original Colorado River bed which runs down the axis of Boulder Basin from Boulder Canyon to Hoover Dam, and the old Las Vegas Creek bed that bisects Las Vegas Bay. The sediment cover along the original Colorado River bed is continuous and is typically greater than 10-m thick throughout much of its length with the thickness in some areas exceeding 35 meters. The flat-lying nature of the deposits suggests that they are the result of turbidity currents that flow the length of the lake. The sediment cover in Las Vegas Bay is much thinner (rarely exceeding 2 m in thickness) and more discontinuous. The source for these sediments presumably is Las Vegas Wash and a series of other ephemeral washes that empty into this part of the lake. The presence of sediments along the entire length of the Las Vegas Creek bed suggests that turbidity currents probably are active here as well, and that sediment has been transported from these streams at least 10 km down the axis of this valley to where it enters Boulder Basin. Alluvial deposits and rock outcrops are still exposed on large parts of the lake floor.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr99581","issn":"0094-9140","usgsCitation":"Twichell, D.C., Cross, V.A., Rudin, M.J., and Parolski, K.F., 1999, Surficial geology and distribution of post-impoundment sediment of the western part of Lake Mead based on a sidescan sonar and high-resolution seismic-reflection survey: U.S. Geological Survey Open-File Report 99-581, 27 leaves :ill.

The water-quality conditions of interest are those that are representative of the general ambient water quality of a given stream reach or area of an aquifer. This report identifies which existing water-quality data are suitable for characterizing general conditions in a nationally consistent manner and describes, to the extent possible, general water-quality conditions in the Cook Inlet Basin in southcentral Alaska. The study unit consists of all lands that drain into Cook Inlet, but not the marine environment itself. \r\n\r\nSurface-water-quality data are summarized for 31 sites on streams. Ground-water quality data are summarized for four regions using analyses from about 550 wells that yield water from unconsolidated glacial and alluvial deposits and analyses from 17 wells in western Cook Inlet, some of which may yield water from coal or weakly consolidated sandstone or conglomerate. The summaries focus on the central tendencies and typical variations in the data and use nonparametric statistics such as frequencies and percentile values. \r\n\r\nFew surface- and ground-water sites have long-term water-quality records and very few data are available for dissolved oxygen, nutrients, metals, trace elements, organic compounds, and radionuclides. In general, most waters in streams and wells have small concentrations of major inorganic constituents, nutrients, trace elements, and organic compounds. \r\n\r\nMost streams have water that is generally suitable for drinking-water supply, the growth and propagation of cold-water anadromous fish, and water-contact recreation. However, suspended-sediment concentrations in glacier-fed streams are naturally high and can make water from glacier-fed streams unsuitable for many uses unless the water is treated to remove the suspended sediment. Several streams and lakes in Anchorage have fecal coliform bacteria concentrations higher than allowed for drinking or water-contact recreation. \r\n\r\nGround water in the major withdrawal regions is generally suitable for drinking and most other purposes, but some wells yield water having nitrate, iron, or arsenic concentrations higher than drinking-water criteria. Ground-water quality has been degraded in several areas as the result of leaks or spills of petroleum products.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri994116","usgsCitation":"Glass, R.L., 1999, Water-quality assessment of the Cook Inlet Basin, Alaska — Summary of data through 1997: U.S. Geological Survey Water-Resources Investigations Report 99-4116, vii, 110 p., https://doi.org/10.3133/wri994116.","productDescription":"vii, 110 p.","costCenters":[],"links":[{"id":393473,"rank":2,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_22564.htm"},{"id":158918,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1999/4116/report-thumb.jpg"},{"id":95632,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1999/4116/report.pdf","size":"12580","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Alaska","otherGeospatial":"Cook inlet Basin","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -154.68749999999997,\n              58.10110549730587\n            ],\n            [\n              -149.0625,\n              58.10110549730587\n            ],\n            [\n              -149.0625,\n              61.87687021463305\n            ],\n            [\n              -154.68749999999997,\n              61.87687021463305\n            ],\n            [\n              -154.68749999999997,\n              58.10110549730587\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4893e4b07f02db520f19","contributors":{"authors":[{"text":"Glass, Roy L.","contributorId":86813,"corporation":false,"usgs":true,"family":"Glass","given":"Roy","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":197927,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Elevation-surface area and elevation-capacity curves summarizing the current relations among elevation, surface area, and storage capacity were created from the bathymetric map. Rainfall and lake-elevation data collected from April 1996 to March 1998 indicated that lake levels correlated to rainfall values with lake elevation rising rapidly in response to heavy rainfall and then returning to normal levels within a few days. Mean lake elevation for the 22 month period of data was 59.5 feet which gives a mean storage capacity of 107 acre-feet and a mean surface area of 24.1 acre. A floating mat of reeds, which covered 58 percent of the lake surface area at the time of the bathymetric survey, makes true storage capacity difficult to estimate. \r\n\r\nWater-quality sampling during April 1996 and November 1997 indicated that no U.S. Environmental Protection Agency primary drinking-water standards were violated for analyzed organic and inorganic compounds and radionuclides. With suitable biological treatment, the lake water could be used for drinking-water purposes. Temperature and dissolved oxygen measurements indicated that Lake Ngardok is stratified. Given that air temperature on Palau exhibits little seasonal variation, it is likely that this pattern of stratification is persistent. As a result, complete mixing of the lake is probably rare. Near anaerobic conditions exist at the lake bottom. Low dissolved oxygen (3.2 milligrams per liter) measured at the outflow indicated that water flowing past the outflow was from the deep oxygen-depleted depths of the lake.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/wri994118","collaboration":"Prepared in cooperation with the Republic of Palau","usgsCitation":"Yeung, C., and Wong, M.F., 1999, Storage Capacity and Water Quality of Lake Ngardok, Babeldaob Island, Republic of Palau, 1996-98: U.S. Geological Survey Water-Resources Investigations Report 99-4118, iv, 26 p., https://doi.org/10.3133/wri994118.","productDescription":"iv, 26 p.","costCenters":[{"id":525,"text":"Pacific Islands Water Science Center","active":true,"usgs":true}],"links":[{"id":124101,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/wri_99_4118.jpg"},{"id":13742,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/wri/wri99-4118/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 134.33333333333334,7.25 ], [ 134.33333333333334,7.75 ], [ 134.75,7.75 ], [ 134.75,7.25 ], [ 134.33333333333334,7.25 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b32e4b07f02db6b42b9","contributors":{"authors":[{"text":"Yeung, Chiu Wang","contributorId":12528,"corporation":false,"usgs":true,"family":"Yeung","given":"Chiu Wang","affiliations":[],"preferred":false,"id":203546,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wong, Michael F.","contributorId":43815,"corporation":false,"usgs":true,"family":"Wong","given":"Michael","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":203547,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Flood-frequency estimates for gaged sites in North Carolina were computed by fitting the annual peak flows for each site to a log-Pearson Type III distribution. As part of the computation of flood-frequency estimates for gaged sites, new values for generalized skew coefficients were developed. Basin characteristics for these gaged sites were computed by using a geographic information system and automated computer algorithms. Flood-frequency estimates and basin characteristics for 317 gaged sites were combined to form the data base that was used for this analysis.</p><p>Regional regression analysis, using generalized least-squares regression, was used to develop a set of predictive equations that can be used to estimate the 2-, 5-, 10-, 25-, 50-, 100-, 200-, and 500-year recurrence interval discharges for rural ungaged basins in the Blue Ridge-Piedmont, Coastal Plain, and Sand Hills hydrologic areas. The predictive equations are all functions of drainage area. Average errors of prediction for these regression equations range from 36 to 65 percent.</p><p>A region-of-influence method also was developed that interactively estimates recurrence interval discharges for rural ungaged basins in the Blue Ridge-Piedmont and Coastal Plain hydrologic areas of North Carolina. Regression techniques are used to develop a unique relation between flood discharge and basin characteristics for a subset of gaged sites with similar basin characteristics. This, then, can be used to estimate flood discharges at ungaged sites. Because the computations required for this method are somewhat complex, a computer application was developed that performs the computations and compares the predictive errors for this method. The computer application also includes the option of using the regression equations to compute estimated flood discharges and errors of prediction specific to each ungaged site.</p><p>Root mean square errors, computed for each recurrence interval and hydrologic area, are generally only slightly lower for the region-of-influence method than for the regression equations and do not provide sufficient basis for recommending one method over the other. In addition, the region-of-influence method is a new method that is still being improved. As a result, the regional regression equations are considered to be the primary method for computing flood-frequency estimates at ungaged sites.</p>","language":"English","publisher":"U.S. Geological

Water companies on Long Island, N.Y., spend several million dollars annually to recondition, redevelop, and replace supply wells and distribution lines; treat dissolved iron with sequestering agents or by filtration; and respond to iron-related complaints by customers. This report summarizes the results of studies done by the U.S. Geological Survey, in cooperation with the Suffolk County Water Authority, to characterize the geochemistry and microbiology of iron in the aquifer system of Suffolk County. This information should be helpful for the siting and operation of supply wells.</p><p>Concentrations of dissolved iron in Long Island's ground water, and the frequency of iron biofouling of wells, are highest in ground-water-discharge zones, particularly near the south shore. Ground water along a deep north-south flowpath of the Magothy aquifer in southwestern Suffolk County becomes anaerobic (oxygen deficient) and Fe(III) reducing at a distance of 8 to 10 kilometers south of the ground-water divide, and this change coincides with the downgradient increase in dissolved iron concentrations. The distribution of organic carbon, and the distribution and local variations in reactivity of Fe(III), in Magothy aquifer sediments have resulted in localized differences in redox microenvironments. For example, Fe(III)-reducing zones are associated with anaerobic conditions, where relatively large amounts of Fe(III) oxyhydroxide grain coatings are present, whereas sulfate-reducing zones are associated with lignite-rich lenses of silt and clay and appear to have developed in response to the depletion of available Fe(III) oxyhydroxides. The sulfate-reducing zones are characterized by relatively low concentrations of dissolved iron (resulting from iron-disulfide precipitation) and may be large enough to warrant water-supply development.</p><p>Specific-capacity and water-quality data from wells screened in the Magothy aquifer indicate that water from biofouled wells contains higher median concentrations of total and dissolved iron and manganese, total phosphate, and dissolved sulfate, and lower median concentrations of dissolved oxygen and alkalinity, and lower pH, than does water from unaffected wells. Corresponding data from wells screened in the upper glacial aquifer indicate that water from biofouled wells contains higher median concentrations of total and dissolved manganese and dissolved sulfate, and lower pH, than does water from unaffected wells.</p><p>Filamentous bacteria were detected in 31 (or 72 percent) of the 43 biofilm samples obtained from biofouled wells during reconditioning.

Four springs at the base of Winsor Point on Winsor Mountain (known collectively as Pipe Spring) are a part of the historical significance of the monument. The relation between declining discharges from springs in the monument and ground-water development north of the monument was studied to provide information that could be used for management of the monument resources.\r\nGround-water elevations from wells indicate that ground-water movement is from north to south along the west side of a branch of Sevier Fault. Faulting in the areas has downthrown permeable water-bearing sediments relative to impermeable sediments and is evinced by cliffs along the western and northern edges and flat-lying areas to the east. The Navajo Sandstone and Kayenta Formation are the primary water-bearing units on the west side of the fault. The semipermeable sediments of the Chinle and Moenkopi Formations on the east side of the fault inhibit ground-water movement from the west to the east side of the fault.\r\nGround water south of Moccasin Canyon is higher in total dissolved solids than ground water north of Moccasin Canyon. Wells north of Moccasin Canyon are open primarily in the Navajo Sandstone, and wells south of Moccasin Canyon are open primarily in the upper sandstone facies of the Kayenta Formation.\r\nA water-budget estimate for the study area indicates a storage deficit of 780 acre-feet per year. This deficit suggests that some recharge may be occurring outside the study area. Oxygen and hydrogen stable- isotopic data suggest no isotopic variation in recharging waters in the study area and surrounding region. Radiocarbon and tritium activities indicate apparent ground-water ages at wells and springs are between 45 and 9,000 years.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/wri984263","usgsCitation":"Truini, M., 1999, Geohydrology of Pipe Spring National Monument area, northern Arizona: U.S. Geological Survey Water-Resources Investigations Report 98-4263, v, 25 p. , https://doi.org/10.3133/wri984263.","productDescription":"v, 25 p.

Daily mean ground-water levels and river stage measured during November 1995- September 1996, simulated daily mean river stage for November 1995-December 1996 derived from simulated daily mean discharge for eight alternative water-management plans for the Missouri River, and simulated daily mean ground-water levels for November 1995- December 1996 for selected water-management plans were used in the study. The measured data represent hydrologic conditions for the Current (1998) Water-Control Plan of the U.S. Army Corps of Engineers.</p>\n<p>Ground-water levels in the alluvial aquifer vary in response to river stage, precipitation, proximity to drainage ditches, evapotranspiration, and pumpage. In Fremont County, measured ground-water levels generally were lower than river stage during the spring, summer, and fall months. In Monona County, measured ground-water levels generally were higher than river stage. Water levels in wells at distances greater than about 8,000 feet from the river in Fremont County and about 6,500 feet in Monona County likely were more affected by precipitation or proximity to drainage ditches than by river stage.</p>\n<p>Changes in river stage likely affect groundwater levels in Fremont County to a greater degree than in Monona County. In Fremont County, the hydraulic gradient generally is from the river to the aquifer; in Monona County, the gradient generally is from the aquifer to the river. The response of ground- water levels to changes in river stage in Monona County is less apparent than in Fremont County. The higher ground-water levels in Monona County indicate that the effects of other factors, such as differences in recharge from precipitation and aquifer properties, are more dominant than in Fremont County.</p>\n<p>Generally, the effects of simulated river stage caused higher simulated ground-water levels in Fremont and Monona Counties at distances less than 10,000 feet from the river during the spring months for selected alternatives to the Current Water-Control Plan that target increased benefits to fish and wildlife. Local hydrogeologic conditions will determine how significantly the possible 1- to 4-foot change in ground-water levels affects land use within 10,000 feet of the river. For example, lower river stage and ground-water levels during the mid-summer months could improve drainage in lowland areas during periods of greater-than-normal precipitation. Actual depth to ground water might be controlled by factors other than river stage, such as proximity to drainage ditches and local differences in recharge by precipitation, discharge from evapotranspiration, aquifer properties, and land-surface altitude.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Iowa City, IA","doi":"10.3133/wri984235","collaboration":"Prepared in cooperation with the Fremont County Board of Supervisors","usgsCitation":"Lucey, K.J., Schaap, B.D., and Fischer, E.E., 1999, Effects on ground-water levels in the Missouri River alluvial aquifer caused by changes in Missouri River stage, Fremont and Monona Counties, Iowa: U.S. Geological Survey Water-Resources Investigations Report 98-4235, iv, 32 p., https://doi.org/10.3133/wri984235.","productDescription":"iv, 32 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":351,"text":"Iowa Water Science Center","active":true,"usgs":true}],"links":[{"id":95713,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1998/4235/report.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":159307,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1998/4235/report-thumb.jpg"},{"id":466121,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_49048.htm","text":"Fremont County","linkFileType":{"id":5,"text":"html"}},{"id":466122,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_49049.htm","text":"Monona County","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"Iowa","county":"Fremont County, Monona County","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -95.88317871093749,\n              40.588928169693745\n            ],\n            [\n              -95.88317871093749,\n              40.76806170936614\n            ],\n            [\n              -95.64147949218749,\n              40.76806170936614\n            ],\n            [\n              -95.64147949218749,\n              40.588928169693745\n            ],\n            [\n              -95.88317871093749,\n              40.588928169693745\n            ]\n          ]\n        ]\n      }\n    },\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -96.2347412109375,\n              41.95949009892465\n            ],\n            [\n              -96.2347412109375,\n              42.04113400940809\n            ],\n            [\n              -96.119384765625,\n              42.04113400940809\n            ],\n            [\n              -96.119384765625,\n              41.95949009892465\n            ],\n            [\n              -96.2347412109375,\n              41.95949009892465\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a26e4b07f02db60fa7a","contributors":{"authors":[{"text":"Lucey, Keith J. kjlucey@usgs.gov","contributorId":185,"corporation":false,"usgs":true,"family":"Lucey","given":"Keith","email":"kjlucey@usgs.gov","middleInitial":"J.","affiliations":[],"preferred":true,"id":199847,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Schaap, Bryan D.","contributorId":63438,"corporation":false,"usgs":true,"family":"Schaap","given":"Bryan","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":199849,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fischer, Edward E. edf@usgs.gov","contributorId":1063,"corporation":false,"usgs":true,"family":"Fischer","given":"Edward","email":"edf@usgs.gov","middleInitial":"E.","affiliations":[],"preferred":true,"id":199848,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

In 1989, the average rate of ground-water withdrawal from the lower unit of the Chicot aquifer in Orange County for municipal and industrial use was 13.8 million gallons per day, a substantial decrease from the historical high of 23.1 million gallons per day in 1972. The average withdrawal for industrial use decreased substantially from 14.4 million gallons per day during 1963?84 to 6.9 million gallons per day during 1985?89. The average withdrawal for municipal use during 1985?89 was 6.8 million gallons per day, similar to the average withdrawal of 5.8 million gallons per day during 1963?84. Water levels in wells in most of the study area rose during 1985?90. The largest rise in water levels was more than 10 feet in parts of Orange and Pinehurst, north of site B (one of three areas of ground-water withdrawal for industrial use), while the largest decline in water levels was a localized decline of more than 60 feet at site C in south-central Orange County (also an area of withdrawal for industrial use). Chemical analyses of ground-water samples from the lower Chicot aquifer during 1985?90 indicate that the aquifer contained mostly freshwater (dissolved solids concentrations less than 1,000 milligrams per liter). Dissolved chloride concentrations remained relatively constant in most wells during 1985?90 but could vary greatly between wells within short distances. Saline-water encroachment continued to occur during 1985?89 but at a slower rate than in the 1970s and early 1980s. On the basis of chemical data collected during 1985?89, a relation was determined between specific conductance and dissolved chloride concentration that can be used to estimate dissolved chloride by multiplying the specific conductance by different factors for low or high conductances.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr99603","usgsCitation":"Kasmarek, M.C., 1999, Ground-water data in Orange County and adjacent counties, Texas, 1985-90: U.S. Geological Survey Open-File Report 99-603, 38 p., https://doi.org/10.3133/ofr99603.","productDescription":"38 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"links":[{"id":135578,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr99603.PNG"},{"id":327872,"rank":101,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1999/ofr99-603/pdf/ofr99-603.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":3684,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/ofr99-603/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b05e4b07f02db6996ef","contributors":{"authors":[{"text":"Kasmarek, Mark C. 0000-0003-2808-2506 mckasmar@usgs.gov","orcid":"https://orcid.org/0000-0003-2808-2506","contributorId":1968,"corporation":false,"usgs":true,"family":"Kasmarek","given":"Mark","email":"mckasmar@usgs.gov","middleInitial":"C.","affiliations":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"preferred":true,"id":227717,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}
