As part of the NAWQA program, benthic invertebrate communities were surveyed at ten sites in nine streams representing the three main types of land use on Oahu: urban, agriculture, and forested. At each sampling site, habitat characteristics were determined at a range of spatial scales including drainage basin, segment, reach, transect, and point. Associations among land use, habitat characteristics, and benthic invertebrate community structure were examined. The rapid population growth and increasing urbanization on Oahu has resulted in substantial stream habitat alteration. Instream habitat characteristics at the urban and mixed (urban and agriculture) land-use sites were markedly different from those at the forested sites. Urban and mixed land-use sites, most of which were channelized, tended to have less riparian vegetation, higher water temperatures, smaller substrate, and higher levels of embeddedness and siltation than sites in forested watersheds. The majority of invertebrate taxa identified during this study were non-native. Invertebrate abundance was lower at urban and mixed land-use sites than at forested sites, while species richness (the number of different species) showed the opposite pattern. Multivariate analyses indicated that invertebrate species composition was similar at sites with similar land use. Aquatic insects of the orders Diptera and Trichoptera were the most common insects in all samples. The ratio of Diptera to Trichoptera abundance varied with urbanization. Forested sites were dominated by Trichoptera, and urban and mixed land-use sites were dominated by Diptera. Molluscs typically occurred in channelized urban streams although no native molluscs were collected during this study. The most abundant molluscs were pan-tropical thiarid snails, the introduced clam Corbicula fluminea, and the limpet Ferrissia sharpi. Two native and four introduced species of Crustacea were collected at the sampling sites. To effectively manage Hawaiian watersheds for native species and the communities they form, the ways in which these species respond to human-induced changes needs to be understood. This report provides important information describing the usefulness of invertebrates as indicators of stream quality conditions and how an integrated assessment of stream quality will allow for the development of appropriate monitoring and management strategies.","language":"ENGLISH","doi":"10.3133/wri034256","usgsCitation":"Brasher, A., Wolff, R.H., and Luton, C.D., 2003, Associations among land-use, habitat characteristics, and invertebrate community structure in nine streams on the island of Oahu, Hawaii: U.S. Geological Survey Water-Resources Investigations Report 2003-4256, 59 p., https://doi.org/10.3133/wri034256.","productDescription":"59 p.","costCenters":[],"links":[{"id":6209,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri034256/","linkFileType":{"id":5,"text":"html"}},{"id":191491,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4aafe4b07f02db66cb2c","contributors":{"authors":[{"text":"Brasher, Anne M.D.","contributorId":33686,"corporation":false,"usgs":true,"family":"Brasher","given":"Anne M.D.","affiliations":[],"preferred":false,"id":281411,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Wolff, Reuben H.","contributorId":35020,"corporation":false,"usgs":true,"family":"Wolff","given":"Reuben","email":"","middleInitial":"H.","affiliations":[],"preferred":false,"id":281412,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Luton, Corene D.","contributorId":24449,"corporation":false,"usgs":true,"family":"Luton","given":"Corene","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":281410,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Geological systems consist of a multiplicity of linked components with nested feedback loops; the dynamics of these systems are non-linear, iterative, multi-scale, and operate far from equilibrium. That notwithstanding, It appears that, with the exception of papers on seismic studies, geology and geophysics work has been disproportionally underrepresented at regional and national meetings on complex systems relative to papers in the life sciences. This is somewhat puzzling because geologists and geophysicists are, in many ways, preadapted to thinking of complex system mechanisms. Geologists and geophysicists think about processes involving large volumes of rock below the sunlit surface of Earth, the accumulated consequence of processes extending hundreds of millions of years in the past. Not only do geologists think in the abstract by virtue of the vast time spans, most of the evidence is out-of-sight.</p>\n<br>\n<p>A primary goal of this workshop is to begin to bridge the gap between the Earth sciences and life sciences through demonstration of the universality of complex systems science, both philosophically and in model structures.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr03364","usgsCitation":"Mossotti, V.G., Barragan, J., and Westergard, T.D., 2003, Cx-02 Program, workshop on modeling complex systems (Version 1.0): U.S. Geological Survey Open-File Report 2003-364, Readme; Report: 52 p.; Participants: DBF, CSV, FP5; Shape files, https://doi.org/10.3133/ofr03364.","productDescription":"Readme; Report: 52 p.; Participants: DBF, CSV, FP5; Shape files","numberOfPages":"53","temporalStart":"2002-11-19","temporalEnd":"2002-11-21","costCenters":[{"id":312,"text":"Geology, Minerals, Energy, and Geophysics Science Center","active":true,"usgs":true}],"links":[{"id":174049,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr03364.jpg"},{"id":285805,"rank":2,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/2003/0364/Cx-02_participants/Cx-02_participants.fp5"},{"id":285804,"rank":3,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/2003/0364/Cx-02_participants/Cx-02_participants.csv"},{"id":285803,"rank":4,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/2003/0364/Cx-02_participants/Cx-02_participants.dbf"},{"id":285808,"rank":5,"type":{"id":7,"text":"Companion Files"},"url":"https://pubs.usgs.gov/of/2003/0364/Shape_files_Cx-02_Participants/Shape_files_Cx-02_Participants.zip"},{"id":285802,"rank":6,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2003/0364/pdf/OF03-364.pdf"},{"id":285801,"rank":7,"type":{"id":20,"text":"Read Me"},"url":"https://pubs.usgs.gov/of/2003/0364/1_README.TXT"},{"id":4881,"rank":8,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2003/0364/","linkFileType":{"id":5,"text":"html"}}],"edition":"Version 1.0","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4acce4b07f02db67ebea","contributors":{"authors":[{"text":"Mossotti, Victor G. mossotti@usgs.gov","contributorId":3494,"corporation":false,"usgs":true,"family":"Mossotti","given":"Victor","email":"mossotti@usgs.gov","middleInitial":"G.","affiliations":[],"preferred":true,"id":246987,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Barragan, Jo Ann","contributorId":97816,"corporation":false,"usgs":true,"family":"Barragan","given":"Jo Ann","affiliations":[],"preferred":false,"id":246989,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Westergard, Todd D.","contributorId":92970,"corporation":false,"usgs":true,"family":"Westergard","given":"Todd","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":246988,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The water volume has been reduced from 2.29 million cubic meters in 1931, to 2.03 million cubic meters in 1986, and to 1.89 million cubic meters in 2001. The average annual storage-capacity loss (equal to the sedimentation rate) of Lago El Guineo was 4,727 cubic meters for the period of 1931 to July 1986 (or 0.21 percent per year), increasing to 5,714 cubic meters for the period of 1931 to October 2001 (or 0.25 percent per year). Discrepancies that could lead to substantial errors in volume calculations in a small reservoir like Lago El Guineo, were found when transferring the field-collected data into the geographic information system data base 1:20,000 U.S. Geological Survey Jayuya, Puerto Rico quadrangle. After verification and validation of field data, the Lago El Guineo shoreline was rectified using digital aerial photographs and differential global positioning data.","language":"ENGLISH","doi":"10.3133/wri034093","usgsCitation":"Soler-Lopez, L.R., 2003, Sedimentation Survey of Lago El Guineo, Puerto Rico, October 2001: U.S. Geological Survey Water-Resources Investigations Report 2003-4093, 21 p., 2 pls, https://doi.org/10.3133/wri034093.","productDescription":"21 p., 2 pls","costCenters":[],"links":[{"id":177503,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":4920,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri034093/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0be4b07f02db5fbd17","contributors":{"authors":[{"text":"Soler-Lopez, Luis R.","contributorId":27501,"corporation":false,"usgs":true,"family":"Soler-Lopez","given":"Luis","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":248836,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Depth to the water table ranged from less than 5 feet below land surface near major streams to more than 75 feet on some of the kame terraces along the valley walls. Saturated thickness of the unconfined aquifer ranged from less than 1 foot near Norwich to more than 200 feet at a kame delta north of Oxford.</p><p>A discontinuous series of confined aquifers is present throughout much of the Chenango River valley north of Oxford.

The reservoir is part of the Puerto Rico Electric Power Authority Toro Negro Hydroelectric Project, which also includes the Lago El Guineo reservoir and a hydroelectric plant to the south of the insular hydrographic divide. Historically, the drainage area had been protected from soil erosion by dense vegetation and the lack of basin development. However, transportation, potable water, and electric power infrastructure construction has facilitated development in rural areas resulting in the clearing of land. This trend in land-use changes is impacting the useful life of Lago de Matrullas. \r\n\r\n  \r\n\r\nThe reservoir storage capacity has been reduced from 3.71 million cubic meters in 1934 to 3.08 million cubic meters in 2001. This represents a total storage-capacity loss of 0.63 million cubic meters by 2001 (17 percent), or a long-term annual storage loss of 0.25 percent per year. The sediment trapping efficiency of Lago de Matrullas has been estimated at approximately 90 percent. If the current long-term sedimentation rate continues, Lago de Matrullas would fill by the year 2328. However, this life expectancy could be reduced at a faster than predicted rate as a result of rural development in the Lago de Matrullas basin and the high sediment trapping efficiency of the reservoir.","language":"ENGLISH","doi":"10.3133/wri034102","usgsCitation":"Soler-Lopez, L.R., 2003, Sedimentation survey of Lago de Matrullas, Puerto Rico, December 2001: U.S. Geological Survey Water-Resources Investigations Report 2003-4102, 24 p., 2 pls, https://doi.org/10.3133/wri034102.","productDescription":"24 p., 2 pls","costCenters":[],"links":[{"id":177502,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":4919,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri034102/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ae4b07f02db5fb812","contributors":{"authors":[{"text":"Soler-Lopez, Luis R.","contributorId":27501,"corporation":false,"usgs":true,"family":"Soler-Lopez","given":"Luis","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":248835,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Glacial ice eroded a preglacial bedrock divide along the northern rim of the Allegheny Plateau and deepened a preglacial valley to form a trough valley. Subsequent meltwater issuing from the ice transported and deposited large amounts of sediment which partly filled the trough. The Tully trough contains three distinct segments—the West Branch valley of the southward-flowing Tioughnioga River in the south, the Valley Heads Moraine near Tully, and the Tully valley of the northward-flowing Onondaga Creek in the north.</p><p>The West Branch valley segment south of the moraine contains a two-aquifer system—a surficial unconfined sand and gravel aquifer and a confined basal sand and gravel aquifer that rests on bedrock, separated by a thick, fine-grained glaciolacustrine fine sand, silt, and clay unit. Water quality in the surficial aquifer is generally good, although it is typically hard. Water in the basal, confined aquifer is more mineralized and yields less water to wells than the surficial aquifer.</p><p>The Valley Heads Moraine near Tully consists of layers of sand and gravel, fine sand, silt, clay, and till. The land surface contains many kettle-hole lakes, ponds, wetlands, and dry depressions. The moraine contains several aquifers, some of which are discontinuous. Water quality in the shallow aquifers is generally good, although hard. Water quality in the deep aquifer is generally good, although slightly mineralized by water discharging upward from shale.</p><p>The Tully valley segment north of the moraine has a confined basal sand-and-gravel aquifer that is overlain by a thick layer of lacustrine silt and clay in the southern part of the valley and becomes interlayered with sand and some fine gravel in the northern part. Most homeowners obtain their water supply from streams or springs along the valley walls or from wells. Water from wells completed in coarse-grained sediment on the north side of the moraine and from the basal aquifer is generally fresh, but water from deep wells finished in the basal aquifer north of Solvay Road contains high concentrations of sodium chloride and calcium sulfate that presumably leached from halite and gypsum minerals within the bedrock.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/wri034112","usgsCitation":"Kappel, W.M., and Miller, T.S., 2003, Hydrogeology of the Tully Trough, southern Onondaga County and northern Cortland County, New York: U.S. Geological Survey Water-Resources Investigations Report 2003-4112, 17 p., https://doi.org/10.3133/wri034112.","productDescription":"17 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"links":[{"id":395403,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_68294.htm"},{"id":177410,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/2003/4112/coverthb.jpg"},{"id":4918,"rank":100,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/2003/4112/wri20034112.pdf","text":"Report","size":"4.50 MB","linkFileType":{"id":1,"text":"pdf"},"description":"WRI 2003-4112"}],"country":"United States","state":"New York","county":"Cortland County, Onondaga County","otherGeospatial":"Tully Trough","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -76.1667,\n              42.7417\n            ],\n            [\n              -76.0953,\n              42.7417\n            ],\n            [\n              -76.0953,\n              42.8592\n            ],\n            [\n              -76.1667,\n              42.8592\n            ],\n            [\n              -76.1667,\n              42.7417\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","contact":"<p>Director, New York Water Science Center<br>U.S. Geological Survey<br> 425 Jordan Rd<br> Troy, NY 12180<br> (518) 285-5695 <br> <a href=\"http://ny.water.usgs.gov/\" data-mce-href=\"http://ny.water.usgs.gov/\">http://ny.water.usgs.gov/</a></p>","tableOfContents":"<ul>\n<li>Abstract</li>\n<li>Introduction</li>\n<li>Geology</li>\n<li>Hydrology</li>\n<li>Summary</li>\n<li>Selected References</li>\n</ul>","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1fe4b07f02db6ab5c7","contributors":{"authors":[{"text":"Kappel, William M. 0000-0002-2382-9757 wkappel@usgs.gov","orcid":"https://orcid.org/0000-0002-2382-9757","contributorId":1074,"corporation":false,"usgs":true,"family":"Kappel","given":"William","email":"wkappel@usgs.gov","middleInitial":"M.","affiliations":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"preferred":true,"id":248833,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Miller, Todd S. tsmiller@usgs.gov","contributorId":1190,"corporation":false,"usgs":true,"family":"Miller","given":"Todd","email":"tsmiller@usgs.gov","middleInitial":"S.","affiliations":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"preferred":true,"id":248834,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Eighteen samples were collected from four watersheds representing land uses characterized predominantly as established commercial, industrial, new commercial, and residential.  Results of water-quality analyses enabled calculation of event-mean concentrations and estimated annual contaminant loads and yields of storm runoff from nonpoint sources for 12 water-quality properties and constituents.  The following water-quality data are reported: physical and chemical-related properties, fecal coliform and enterococci bacteria, major inorganic ions, nutrients, trace elements, and organic compounds.  \r\n\r\nThe residential land-use is the largest of the watersheds (550 acres), which resulted in high estimated annual contaminant loads compared to other watersheds for 8 of the 12 water-quality properties and constituents.  This may indicate that the size of the watershed and runoff from residences with their associated contaminants had substantial effects on annual loads within this land use.  The industrial land-use area had the highest estimated annual contaminant loads for metals, followed by the residential landuse area.  However, when comparing yields among the watersheds, the industrial watershed had the highest yield for 9 of the 12 water-quality properties and constituents, whereas the residential watershed had the lowest yield for 7 of the 12.  The industrial watershed yielded more metals per acre per year than any other watershed.  Zinc yields were 2.71 pounds per acre per year from the industrial watershed, compared to 0.35 pounds per acre per year from the residential watershed, which was the lowest of all the watersheds.  Lead concentrations exceeded the U.S. Environmental Protection Agency Maximum Contaminant Level of 15 micrograms per liter for drinking water standards in 10 of 18 samples.  Low-level concentrations of mercury were detected twice at both the new commercial and residential sites, with all concentrations at or just above reporting limits.  The average dissolved phosphorus concentrations from each land use were two to four times higher than the U.S. Environmental Protection Agency criterion of 0.05 milligrams per liter.  Diazinon, which is widely used as a general-purpose insecticide for lawns and gardens, was detected in all 18 samples.  The maximum diazinon concentration detected, 2.7 micrograms per liter, was from the residential site.  Malathion, another insecticide used on lawns, gardens, and plants, was also detected at least once from each site, but all concentrations were below the minimum detection limit of 0.1 micrograms per liter.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wri20034212","collaboration":"Prepared in cooperation with the City of Baton Rouge and East Baton Rouge

This analysis is an evaluation of the proposed Geography Discipline initiative to provide the Nation with a mechanism to access current and consistent digital geospatial data. This CBA is a supporting document to accompany the Exhibit 300 Capital Asset Plan and Business Case of The National Map Reengineering Program. \r\n\r\nThe framework for estimating the benefits is based on expected improvements in processing information to perform any of the possible applications of spatial data. This analysis does not attempt to determine the benefits and costs of performing geospatial-data applications. Rather, it estimates the change in the differences between those benefits and costs with The National Map and the current situation without it. The estimates of total costs and benefits of The National Map were based on the projected implementation time, development and maintenance costs, rates of data inclusion and integration, expected usage levels over time, and a benefits estimation model. \r\n\r\nThe National Map provides data that are current, integrated, consistent, complete, and more accessible in order to decrease the cost of implementing spatial-data applications and (or) improve the outcome of those applications. The efficiency gains in per-application improvements are greater than the cost to develop and maintain The National Map, meaning that the program would bring a positive net benefit to the Nation. The average improvement in the net benefit of performing a spatial data application was multiplied by a simulated number of application implementations across the country. The numbers of users, existing applications, and rates of application implementation increase over time as The National Map is developed and accessed by spatial data users around the country. \r\n\r\nResults from the 'most likely' estimates of model parameters and data inputs indicate that, over its 30-year projected lifespan, The National Map will bring a net present value (NPV) of benefits of $2.05 billion in 2001 dollars. The average time until the initial investments (the break-even period) are recovered is 14 years. Table ES-1 shows a running total of NPV in each year of the simulation model. In year 14, The National Map first shows a positive NPV, and so the table is highlighted in gray after that point. Figure ES-1 is a graph of the total benefit and total cost curves of a single model run over time. The curves cross in year 14, when the project breaks even. A sensitivity analysis of the input variables illustrated that these results of the NPV of The National Map are quite robust. Figure ES-2 plots the mean NPV results from 60 different scenarios, each consisting of fifty 30-year runs. The error bars represent a two-standard-deviation range around each mean. \r\n\r\nThe analysis that follows contains the details of the cost-benefit analysis, the framework for evaluating economic benefits, a computational simulation tool, and a sensitivity analysis of model variables and values.","language":"ENGLISH","doi":"10.3133/cir1271","usgsCitation":"Halsing, D.L., Theissen, K., and Bernknopf, R., 2003, A cost-benefit analysis of The National Map: U.S. Geological Survey Circular 1271, 49 p., https://doi.org/10.3133/cir1271.","productDescription":"49 p.","costCenters":[],"links":[{"id":181730,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":5902,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/circ/2004/1271/","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e48cde4b07f02db5449fd","contributors":{"authors":[{"text":"Halsing, David L.","contributorId":35809,"corporation":false,"usgs":true,"family":"Halsing","given":"David","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":257946,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Theissen, Kevin","contributorId":107779,"corporation":false,"usgs":true,"family":"Theissen","given":"Kevin","affiliations":[],"preferred":false,"id":257948,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Bernknopf, Richard","contributorId":51701,"corporation":false,"usgs":true,"family":"Bernknopf","given":"Richard","affiliations":[],"preferred":false,"id":257947,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The \n\ndata were collected from wells screened in shallow sands (less than 350 feet below land surface) \n\nin two major aquifer systems--the Chicot aquifer system in southwestern Louisiana and the Chicot \n\nequivalent aquifer system in southeastern Louisiana and southwestern Mississippi.  The Chicot \n\nequivalent aquifer system is part of the Southern Hills regional aquifer system, and both the \n\nChicot aquifer system and the Southern Hills regional aquifer systems are designated as \n\nsole-source aquifers by the U.S. Environmental Protection Agency (USEPA).\n\nThe well depths ranged from 40 to 340 feet below land surface with a median depth of 120 feet.  \n\nThe ground-water-quality data included 5 physiochemical properties, dissolved solids, 9 major \n\ninorganic ions, 24 trace elements, 6 nutrients, dissolved organic carbon, 109 pesticides and \n\ndegradation products, and 85 volatile organic compounds (VOC's); and a subset of the wells were \n\nsampled for radon, chlorofluorocarbons, and stable isotopes.\n\nWater from 35 of the 60 domestic wells sampled had pH values less than the USEPA Seconday \n\nMaximum Contaminant Level (SMCL) range of 6.5 to 8.5 standard units.  Specific conductance \n\nranged from 17 to 1,420 microsiemens per centimeter at 25 degrees Celsius.  Dissolved-solids \n\nconcentrations in water from two wells exceeded the SMCL of 500 mg/L (milligrams per liter); the \n\nmaximum concentration was 858 mg/L.  Sodium and calcium were the dominant cations, and \n\nbicarbonate and chloride were the dominant anions.  One chloride concentration (264 mg/L) \n\nexceeded the SMCL of 250 mg/L.  One arsenic concentration (55.3 micrograms per liter) exceeded \n\nthe USEPA Maximum Contaminant Level (MCL) of 10 micrograms per liter.  Iron concentrations in \n\nwater from 22 wells exceeded the SMCL of 300 micrograms per liter; the maximum concentration was \n\n8,670 micrograms per liter.  Manganese concentrations in water from 26 wells exceeded the SMCL \n\nof 50 micrograms per liter; the maximum concentration was 481 micrograms per liter.  Health \n\nAdvisories have been established for six of the trace elements analyzed; no concentrations were \n\ngreater than these nonenforceable standards.  Radon concentrations in water from 9 of 50 wells \n\nsampled were greater thanthe proposed USEPA MCL of 300 picocuries per liter.\n\nConcentrations of ammonia, ammonia plus organic nitrogen, and nitrite plus nitrate in water from \n\nfour wells were greater than 2 mg/L, a level that might indicate anthropogenic influences.  The \n\nmedian dissolved organic carbon concentration was an estimated 0.30 mg/L, which indicated \n\nnaturally occurring dissolved organic carbon conditions in the study area.  Eight pesticides and \n\ntwo degradation products were detected in water from five wells.  Twenty-four VOC's were \n\ndetected in water from 44 wells.  All concentrations of pesticides and VOC's were less than \n\nUSEPA drinking-water standards.\n\nQuality-control samples, which included field-blank samples, replicates, and field and \n\nlaboratory spikes, indicated no bias in ground-water data from collection procedures or \n\nanalyses.  VAriance between the environmental sampls and he corresponding replicate samples was \n\ntypically less than 5 percent, indicating and acceptable degree of laboratory precision and data \n\ncollection reproducibility.\n\nThe Mann-Whitney rank-sum test was used to compare depth to top of screen and selected physicochemical properties and chemical constituents between six groups of wells.

Results of 1937 and 1964 topographic surveys indicate that sedimenta-tion, primarily from Squaw Creek and Davis Creek inflows, had substantially reduced Refuge pool volumes and depths. A study was undertaken by the U.S. Geological Survey, in cooperation with the U.S. Fish and Wildlife Service, to quantify and spatially analyze historic rates of sedimentation in the Refuge and determine the surface elevations, depths, and pool capacities for selected managed pools from a 2002 survey.The 1937 to 1964 mean total sediment depo-sition, in the area corresponding to the 2002 sur-veyed pool area (about 4,900 acres), was 1.26 ft (feet), or 0.047 ft/yr (foot per year). Mean annual rates of deposition, by pool, from 1937 to 1964 varied from 0.016 to 0.083 ft/yr. From 1964 to 2002, the mean total sediment deposition in the 2002 surveyed pools was 0.753 ft, or 0.020 ft/yr. Therefore, the mean rate of sediment-depth accu-mulation from 1964 to 2002 was about 42 percent of the mean 1937 to 1964 rate, or a 58 percent reduction. Mean annual rates of deposition by pool from 1964 to 2002 varied from 0.010 to 0.049 ft/yr. Despite a substantial reduction in the average sediment accumulation rate for the Refuge, 5 of the 15 separate pools for which annual rates were calculated for both periods showed a small increase in the deposition rates of up to 0.008 ft/yr. Sediment deposits have resulted in a sub-stantial cumulative loss of volume in the Refuge pools since 1937. The 1937 to 2002 total sediment volume deposited in the 2002 surveyed pool area was about 9,900 acre-ft (acre-feet), or 152 acre-ft/yr (acre-feet per year). The volume of sediment deposited from 1937 to 1964 for these pools was about 6,200 acre-ft, or 230 acre-ft/yr. The volume deposited from 1964 to 2002 was about 3,700 acre-ft, or 97.3 acre-ft/yr.Bulk density values were determined from sediment cores collected from 22 sites in the Ref-uge and the bulk densities, along with sediment volumes, allowed for the calculation of sediment mass contributions to the Refuge. From 1937 to 2002, about 10,300,000 tons of sediment were deposited in the 2002 surveyed area, or 32.4 tons/acre/yr (tons per acre per year). The total computed mass of sediment deposited between 1937 and 1964 was about 6,510,000 tons, or an average of 49.1 tons/acre/yr. The total mass depos-ited from 1964 to 2002 in surveyed pools was about 3,830,000 tons, or an average of 20.5 tons/acre/yr. As with sediment thickness compari-sons, the rate of sediment mass deposition between 1964 to 2002 was about 42 percent of that from 1937 to 1964, or a 58 percent reduction.The greatest amounts of sediment deposition in the Refuge for 1937 to 2002 have been near the Squaw Creek and Davis Creek inflow spillway locations. Sediment depths in some areas near former inflow locations have exceeded 8 ft. Relo-cation of an inflow spillway effectively reduced additional sediment deposition at the original loca-tion, and caused increased sedimentation at the new inflow location. This is most clearly depicted in a pool located in the north section of the Refuge that directly received Squaw Creek inflows from 1937 to 1964 and had a mean deposition rate of 0.081 ft/yr reduced to 0.012 ft/yr, from 1964 to 2002, after inflows were redirected and erosion-management plans were implemented in the con-tributing basins.","language":"ENGLISH","doi":"10.3133/wri034211","usgsCitation":"Heimann, D.C., and Richards, J.M., 2003, Topography and Sedimentation Characteristics of the Squaw Creek National Wildlife Refuge, Holt County, Missouri, 1937-2002: U.S. Geological Survey Water-Resources Investigations Report 2003-4211, iv, 52 p. : ill.

In recent years, the demand in some areas has resulted in withdrawals from the Sparta aquifer that substantially exceed replenishment of the aquifer. Considerable drawdown has occurred in the potentiometric surface forming regional cones of depression as water is removed from storage by withdrawals. These cones of depression are centered beneath the Grand Prairie area and the cities of Pine Bluff and El Dorado in Arkansas, and Monroe in Louisiana. The rate of decline for hydraulic heads in the aquifer has been greater than 1 foot per year for more than a decade in much of southern Arkansas and northern Louisiana where hydraulic heads are now below the top of the Sparta Sand. Continued hydraulic-head declines have caused water users and managers alike to question the ability of the aquifer to supply water for the long term. Concern over protecting the Sparta aquifer as a sustainable resource has resulted in a continued, cooperative effort by the Arkansas Soil and Water Conservation Commission, U.S. Army Corps of Engineers, and the U.S. Geological Survey to develop, maintain, and utilize numerical ground-water flow models to manage and further analyze the ground-water system. The work presented in this report describes the development and calibration of a ground-water flow model representing the Sparta aquifer to simulate observed hydraulic heads, documents major differences in the current Sparta model compared to the previous Sparta model calibrated in the mid-1980's, and presents the results of three hypothetical future withdrawal scenarios. \r\n\r\nThe current Sparta model-a regional scale, three-dimensional numerical ground-water flow model-was constructed and calibrated using available hydrogeologic, hydraulic, and water-use data from 1898 to 1997. Significant changes from the previous model include grid rediscretization of the aquifer, extension of the active model area northward beyond the Cane River Formation facies change, and representation of model boundaries. The current model was calibrated with the aid of parameter estimation, a nonlinear regression technique, combined with trial and error parameter adjustment using a total of 795 observations from 316 wells over 4 different years-1970, 1985, 1990, and 1997. The calibration data set provides broad spatial and temporal coverage of aquifer conditions. Analysis of the residual statistics, spatial distribution of residuals, simulated compared to observed hydrographs, and simulated compared to observed potentiometric surfaces were used to analyze the ability of the calibrated model to simulate aquifer conditions within acceptable error. The calibrated model has a root mean square error of 18 feet for all observations, an improvement of more than 12 feet from the previous model. \r\n\r\nThe current Sparta model was used to predict the effects of three hypothetical withdrawal scenarios on hydraulic heads over the period 1998-2027 with one of those extended indefinitely until equilibrium conditions were attained, or steady state. In scenario 1a, withdrawals representing the time period from 1990 to 1997 was held constant for 30 years from 1998 to 2027. Hydraulic heads in the middle of the cone of depression centered on El Dorado decreased by 10 feet from the 1997 simulation to 222 feet below NGVD of 1929 in 2027.

During April through September 2001, six monthly water samples for analysis of pesticides were collected from 22 sites: 17 sites were on 11 streams, and 5 sites were on 5 lakes.  During Apirl through July 2001, four monthly samples for analysis of oil and grease were collected from 5 sites: 4 sites were on three streams, and 1 site was on a lake.\r\n\r\nA total of 131 water samples were analyzed for 17 pesticides (15 insecticides and 2 herbicides).  The following classes of pesticides, as classified from the Pesticide Analysis (U.S. Environmental Protection Agency Region 6 Laboratory), are reported: organochlorine, nitrogen-phosphorus, and carbamate.  The 8 pesticides detected in samples, in decreasing frequency, were as follow: atrazine, molinate, methyl parathion, 4,4'-DDT, carbofuran, diazinon, toxaphene, and 4,4'DDE.\r\n\r\nOrganochlorine pesticides (insecticides) represented the majority (12 out of 17) of the pesticides analyzed.  Of those 12 organochlorine pesticides, only 3 (4,4'-DDT, 4,4'-DDE, and toxaphene) were detected in the 131 samples.  Of the organochlorine pesticides, 4,4'-DDT was detected most frequently (in 11 percent of the samples), and concentrations ranged from 1.22 to 4.70 ng/L (nanograms per liter).\r\n\r\nNitrogen-phosphorus pesticides were the most frequently detected and abundant pesticides.  Of all the pesticides analyzed, atrazine and molinate (nitrogen-phosphorus herbicides) were the pesticides most frequently detected (in 93 and 21 percent of the samples), had the highest and most wide-ranging concentrations (10.8 to 15,100 ng/L and 10.0 to 11,600 ng/L), and were most widely distributed throughout the study area.\r\n\r\nCarbofuran, a carbamate insecticide, was detected at 8 of the 22 pesticide data-collection sites and in 9.2 percent of the 131 samples analyzed for pesticides.  Concentrations of carbofuran ranged from 30.7 to 946 ng/L.\r\n\r\nOf the 22 pesticide data-collection sites, the frequency of pesticide detection was highest at 6 sites:  Boeuf River near Arkansas-Louisiana State Line, Boeuf River near Fort Necessity, Big Creek at Louisiana Highway 135 near Winnsboro, Crew Lake at Crew Lake, Joe's Bayou near Waverly; and Bayou Macon at Louisiana Highway 562 near Wisner.

Organochlorine, chlorophenoxy acid, and organophosphorus pesticides; polychlorinated biphenyls (PCB's); and trace elements were analyzed in surface water and bottom material from three sites previously sampled in a 1981-82 survey. Surface water at six sites was sampled and analyzed for selected nutrients and major inorganic ions based on their importance to human health, the health of the marshes of the Barataria Preserve, or their usefulness in tracking the circulation of Mississippi River water in the Barataria Preserve. Southern Louisiana was in a moderate to severe drought during most of the sampling period, which elevated salinity in the Barataria Preserve for at least 8 months. Specific conductance values were less than 3,000&nbsp; µS/cm (microsiemens per centimeter at 25 degrees Celsius) in surface water throughout the Barataria Preserve from March through September 1999. Specific conductance values increased over the next 2 months and then remained between 5,000 and 6,000 µS/cm. The herbicide 2,4-D was detected in water at the two sites sampled in August 1999 but not at any site during the two other sampling times. Iron, manganese, and the trace elements copper, nickel, and zinc were detected in dissolved and whole-water samples at all three sites. Nitrite+ nitrate, as nitrogen, concentrations ranged from less than 0.002 to 0.19 mg/L (milligrams per liter). Ammonia, as nitrogen, concentrations ranged from less than 0.01 to 0.16 mg/L. Orthophosphate, as phosphorus, concentrations ranged from less than 0.002 to 0.14 mg/L. Calcium, magnesium, potassium, sulfate, and chloride concentrations in surface water were elevated due to the marine influence on the composition of surface water in the Barataria Preserve during the sampling period. Sulfate and chloride concentrations reached 379 and 2,830 mg/L, respectively. Polychlorinated biphenyls, chlordane, and DDT were detected in bottom material. Trace elements were detected in bottom material at all three of the sampled sites. Arsenic concentrations ranged from 4 to 9 µg/g (micrograms per gram) and lead concentrations from 20 to 31 µg/g. Mercury concentrations also were above laboratory reporting levels (LRL's) for bottom material at all three sites. The herbicide 2,4-D was detected in surface water during both surveys. Other organic compounds were not detected in surface water. Mercury and chromium were detected in surface water at all three sites during the 1981-82 survey but were below LRL?s during the 1999-2000 survey. Changes in chemical characteristics of bottom material occurred during the years between the 1981-82 and 1999-2000 surveys. DDT decreased in the bottom material at Bayou Segnette near Barataria. DDE, a degradation product, increased at this site, indicating that over time, DDT concentrations are decreasing in bottom material. PCB's were present in similar concentrations (Bayou Segnette near Barataria) or increased (Bayou Segnette 4.6 miles below Westwego) from 1981-82 to 1999-2000. Cadmium concentrations consistently decreased by half or more at all three sites from 1981-82 to 1999-2000. Mercury concentrations were consistently lower at all three sites in the 1999-2000 survey, but the differences from the 1981-82 survey were small. Chromium concentrations increased at two of the three sites from 1981-82 to the present survey. At the third site, no chromium value was available for the earlier survey. Concentrations of copper and nickel increased in bottom material at the two sites on Bayou Segnette, but decreased at Kenta Canal northwest of Westwego. Probable Effects Levels (PEL's) and Interim Sediment Quality Guidelines (ISQG's) concentrations, as tabulated by the Canadian Council of Ministers of the&nbsp; of the Environment, were used to assess the probability of biological&nbsp;impairment in the Barataria Preserve. PEL’s are concentrations of a chemical at or above which&nbsp;some biological impairment is likely. ISQG concentrations are those at or below which biological impairment is unlikely.&nbsp;Concentrations of 2,4-D and trace elements, when detected in surface water, were substantially lower than levels at&nbsp;which biological impairment could be expected. Concentrations of organic compounds in bottom material were at most less than 25 percent of&nbsp;PEL’s, and usually much lower. Arsenic, cadmium, copper, and lead concentrations in bottom material were generally slightly above or lower&nbsp;than ISQG concentrations in both surveys, although arsenic was as high as 53 percent of PEL’s at one site in the 1999-2000 survey.&nbsp;All other trace elements in bottom material were present in concentrations lower than ISQG concentrations.<br><br><br></p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/wri034038","usgsCitation":"Swarzenski, C.M., 2003, Resurvey of quality of surface water and bottom material of the Barataria Preserve of Jean Lafitte National Historical Park and Preserve, Louisiana, 1999-2000: U.S. Geological Survey Water-Resources Investigations Report 2003-4038, iv, 28 p. , https://doi.org/10.3133/wri034038.","productDescription":"iv, 28 p.
