The goal of the Onondaga Lake Partnership geographic information system is to integrate the various types of spatial data used for scientific investigations, resource management, and planning and design of improvement projects in the Onondaga Lake Watershed. A needs-assessment survey was conducted and a spatial data framework developed to support the Onondaga Lake Partnership use of geographic information system technology. The design focused on the collection, management, and distribution of spatial data, maps, and internet mapping applications. A geographic information system library of over 100 spatial datasets and metadata links was assembled on the basis of the results of the needs assessment survey. Implementation options were presented, and the Geographic Information System Planning Committee offered recommendations for the management and distribution of spatial data belonging to Onondaga Lake Partnership members. The Onondaga Lake Partnership now has a strong foundation for building a comprehensive geographic information system for the Onondaga Lake watershed. The successful implementation of a geographic information system depends on the Onondaga Lake Partnership’s determination of: (1) the design and plan for a geographic information system, including the applications and spatial data that will be provided and to whom, (2) the level of geographic information system technology to be utilized and funded, and (3) the institutional issues of operation and maintenance of the system.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20041259","collaboration":"Prepared in cooperation with the Onondaga Lake Partnership","usgsCitation":"Freehafer, D.A., and Pierson, O., 2004, Onondaga Lake Watershed – A Geographic Information System Project Phase I – Needs assessment and spatial data framework: U.S. Geological Survey Open-File Report 2004-1259, iv, 79 p., https://doi.org/10.3133/ofr20041259.","productDescription":"iv, 79 p.","onlineOnly":"Y","additionalOnlineFiles":"N","costCenters":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"links":[{"id":323378,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2004/1259/ofr20041259.pdf","text":"Report","size":"2.35 MB","linkFileType":{"id":1,"text":"pdf"},"description":"OFR 2004-1259"},{"id":191790,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2004/1259/coverthb.jpg"}],"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&nbsp;<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&nbsp;</li>\n<li>Introduction</li>\n<li>Needs Assessment&nbsp;</li>\n<li>Spatial Data Framework</li>\n<li>Summary and Conclusions</li>\n<li>Appendixes</li>\n</ul>","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4af3e4b07f02db6919c8","contributors":{"authors":[{"text":"Freehafer, Douglas A. dfreehaf@usgs.gov","contributorId":5181,"corporation":false,"usgs":true,"family":"Freehafer","given":"Douglas","email":"dfreehaf@usgs.gov","middleInitial":"A.","affiliations":[{"id":474,"text":"New York Water Science Center","active":true,"usgs":true}],"preferred":false,"id":285237,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pierson, Oliver","contributorId":90830,"corporation":false,"usgs":true,"family":"Pierson","given":"Oliver","email":"","affiliations":[],"preferred":false,"id":285238,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Statistically significant differences in abundance of Cladium pollen in surface samples collected throughout the system allow differentiation of these communities in the sedimentary pollen record. Analysis of pollen in cores from the three transects indicates that the general distribution of ridges and sloughs has remained distinct through time. There is evidence the vegetation has responded to past global-scale climate events, such as the Medieval Warm Period, as well as the 20th century anthropogenic alterations to the natural hydrology. The ridge community is more responsive and susceptible to perturbations in hydrology than the slough community. In contrast, the slough plant community is more stable and less likely to demonstrate long-term changes after perturbations to hydrology.

Because of the importance of this ground-water resource, numerous communities, including the city of Mason in Ingham County, have begun local Wellhead Protection Programs. In these programs, communities protect their groundwater resource by identifying the areas that contribute water to production wells and potential sources of contamination, and by developing methods to manage and minimize threats to the water supply. In addition, some communities in Michigan are concerned about water availability, particularly in areas experiencing water-level declines in the vicinity of quarry dewatering operations. In areas where Wellhead Protection Programs are implemented and there are potential threats to the water supply, residents and communities need adequate information to protect the water supply.</p><p>In 1996, a regional ground-water-flow model was developed by the U.S. Geological Survey to simulate ground-water flow in Clinton, Eaton, and Ingham Counties. This model was developed primarily to simulate the bedrock ground-waterflow system; ground-water flow in the unconsolidated glacial sediments was simulated to support analysis of flow in the underlying bedrock Saginaw aquifer. Since its development in 1996, regional model simulations have been conducted to address protection concerns and water availability questions of local water-resources managers. As a result of these continuing model simulations, additional hydrogeologic data have been acquired in the Tri-County region that has improved the characterization of the simulated ground-water-flow system and improved the model calibration. A major benefit of these updates and refinements is that the regional Tri-County model continues to be a useful tool that improves the understanding of the ground-water-flow system in the Tri-County region, provides local water-resources managers with a means to answer ground-water protection and availability questions, and serves as an example that can be applied in other areas of the state.</p><p>A refined version of the 1996 Tri-County regional ground-water-flow model, developed in 1997, was modified with local hydrogeologic information in the Vevay Township area in Michigan. This model, updated in 2003 for this study, was used to simulate ground-water flow to address groundwater protection and availability questions in Vevay Township. The 2003 model included refinement of glacial and bedrock hydraulic characteristics, better representation of the degree of connection between the glacial deposits and the underlying Saginaw aquifer, and refinement of the model cell size.</p><p>The 2003 model was used to simulate regional groundwater flow, to delineate areas contributing recharge and zones of contribution to production wells in the city of Mason, and to simulate the effects of present and possible future withdrawals. The areal extent of the 10- and 40-year areas contributing recharge and the zones of contribution for the city of Mason's production wells encompass about 2.3 and 6.2 square miles, respectively. Simulation results, where withdrawals for quarry operations were represented by one well pumping at 1.6 million gallons per day, indicate that water levels would decline slightly over 1 foot approximately 2 miles from the quarry in the glacial deposits and in the Saginaw aquifer. With a reduction of the local riverbed conductance or removal of local river model cells representing Mud Creek, water-level declines would extend further west of Mud Creek and further to the north, east, and south of the simulated quarry. Simulation results indicate that water withdrawn for quarry dewatering operations would decrease ground-water recharge to nearby Mud Creek, would increase ground-water discharge from Mud Creek, and that local water levels would be lowered as a result.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20041270","usgsCitation":"Luukkonen, C.L., and Simard, A., 2004, Simulation of ground-water flow in the Vevay Township area, Ingham County, Michigan: U.S. Geological Survey Open-File Report 2004-1270, v, 34 p., https://doi.org/10.3133/ofr20041270.","productDescription":"v, 34 p.","numberOfPages":"39","costCenters":[{"id":382,"text":"Michigan Water Science Center","active":true,"usgs":true}],"links":[{"id":185740,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2004/1270/report-thumb.jpg"},{"id":343655,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2004/1270/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Michigan","county":"Ingham County","otherGeospatial":"Vevay Township Area","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-84.1593,42.7779],[-84.1519,42.685],[-84.146,42.5999],[-84.1402,42.4239],[-84.2539,42.4236],[-84.2607,42.4242],[-84.3676,42.4242],[-84.3677,42.4224],[-84.4864,42.4215],[-84.6026,42.4215],[-84.6039,42.5092],[-84.6034,42.5965],[-84.6062,42.7693],[-84.4856,42.7702],[-84.3657,42.7701],[-84.3649,42.7746],[-84.1593,42.7779]]]},\"properties\":{\"name\":\"Ingham\",\"state\":\"MI\"}}]}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49f8e4b07f02db5f276e","contributors":{"authors":[{"text":"Luukkonen, Carol L. clluukko@usgs.gov","contributorId":3489,"corporation":false,"usgs":true,"family":"Luukkonen","given":"Carol","email":"clluukko@usgs.gov","middleInitial":"L.","affiliations":[{"id":382,"text":"Michigan Water Science Center","active":true,"usgs":true}],"preferred":true,"id":283544,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Simard, Andreanne","contributorId":34180,"corporation":false,"usgs":true,"family":"Simard","given":"Andreanne","email":"","affiliations":[],"preferred":false,"id":283545,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The Mahanoy Creek Basin encompasses an area of 157 square miles (407 square kilometers) including approximately 42 square miles (109 square kilometers) underlain by the Western Middle Anthracite Field. As a result of more than 150 years of anthracite mining in the basin, ground water, surface water, and streambed sediments have been adversely affected. Leakage from streams to underground mines and elevated concentrations (above background levels) of acidity, metals, and sulfate in the AMD from flooded underground mines and (or) unreclaimed culm (waste rock) degrade the aquatic ecosystem and impair uses of the main stem of Mahanoy Creek from its headwaters to its mouth on the Susquehanna River. Various tributaries also are affected, including North Mahanoy Creek, Waste House Run, Shenandoah Creek, Zerbe Run, and two unnamed tributaries locally called Big Mine Run and Big Run. The Little Mahanoy Creek and Schwaben Creek are the only major tributaries not affected by mining. To assess the current hydrological and chemical characteristics of the AMD and its effect on receiving streams, and to identify possible remedial alternatives, the U.S. Geological Survey (USGS) began a study in 2001, in cooperation with the Pennsylvania Department of Environmental Protection and the Schuylkill Conservation District.\r\n\r\nAquatic ecological surveys were conducted by the USGS at five stream sites during low base-flow conditions in October 2001. Twenty species of fish were identified in Schwaben Creek near Red Cross, which drains an unmined area of 22.7 square miles (58.8 square kilometers) in the lower part of the Mahanoy Creek Basin. In contrast, 14 species of fish were identified in Mahanoy Creek near its mouth at Kneass, below Schwaben Creek. The diversity and abundance of fish species in Mahanoy Creek decreased progressively upstream from 13 species at Gowen City to only 2 species each at Ashland and Girardville. White sucker (Catostomus commersoni), a pollution-tolerant species, was present at each of the surveyed reaches. The presence of fish at Girardville was unexpected because of the poor water quality and iron-encrusted streambed at this location. Generally, macroinvertebrate diversity and abundance at these sites were diminished compared to Schwaben Creek and other tributaries draining unmined basins, consistent with the observed quality of streamwater and streambed sediment.\r\n\r\nData on the flow rate and chemistry for 35 AMD sources and 31 stream sites throughout the Mahanoy Creek Basin were collected by the USGS during high base-flow conditions in March 2001 and low base-flow conditions in August 2001. A majority of the base-flow streamwater samples met water-quality standards for pH (6.0 to 9.0); however, few samples downstream from AMD sources met criteria for acidity less than alkalinity (net alkalinity = 20 milligrams per liter as CaCO3) and concentrations of dissolved iron (0.3 milligram per liter) and total manganese (1.0 milligram per liter). Iron, aluminum, and various trace elements including cobalt, copper, lead, nickel, and zinc, were present in many streamwater samples at concentrations at which continuous exposure can not be tolerated by aquatic organisms without an unacceptable effect. Furthermore, concentrations of sulfate, iron, manganese, aluminum, and (or) beryllium in some samples exceeded drinking-water standards. Other trace elements, including antimony, arsenic, barium, cadmium, chromium, selenium, silver, and thallium, did not exceed water-quality criteria for protection of aquatic organisms or human health. Nevertheless, when considered together, concentrations of iron, manganese, arsenic, cadmium, chromium, copper, lead, nickel, and zinc in a majority of the streambed sediment samples from Mahanoy Creek and ","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/sir20045291","collaboration":"Prepared in cooperation with the Schuylkill Conservation District and the Pennsylvania Department of Environmental Protection","usgsCitation":"Cravotta, C.A., 2004, Effects of Abandoned Coal-Mine Drainage on Streamflow and Water Quality in the Mahanoy Creek Basin, Schuylkill, Columbia, and Northumberland Counties, Pennsylvania, 2001: U.S. Geological Survey Scientific Investigations Report 2004-5291, Available online and on CD-ROM; Report: vi, 60 p., https://doi.org/10.3133/sir20045291.","productDescription":"Available online and on CD-ROM; Report: vi, 60 p.","costCenters":[{"id":532,"text":"Pennsylvania Water Science Center","active":true,"usgs":true}],"links":[{"id":186183,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":10549,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2004/5291/","linkFileType":{"id":5,"text":"html"}}],"geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -76.91666666666667,40.5 ], [ -76.91666666666667,41 ], [ -76,41 ], [ -76,40.5 ], [ -76.91666666666667,40.5 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a4ae4b07f02db62526f","contributors":{"authors":[{"text":"Cravotta, Charles A.

The U.S. Geological Survey, in cooperation with the U.S. Air Force, completed 30 slug tests in October 2002 and August 2003 to obtain estimates of horizontal hydraulic conductivity to use as initial values in a ground-water-flow model for the site. The tests were done by placing a polyvinyl-chloride slug of known volume beneath the water level in selected wells, removing the slug, and measuring the resulting water-level recovery over time. The water levels were measured with a pressure transducer and recorded with a data logger. Hydraulic-conductivity values were estimated from an analytical relation between the instantaneous displacement of water in a well bore and the resulting rate of head change. Although nearly two-thirds of the tested wells recovered 90 percent of their slug-induced head change in less than 2 minutes, 90-percent recovery times ranged from 3 seconds to 35 minutes. The estimates of hydraulic conductivity range from 0.2 to 200 feet per day. Eighty-three percent of the estimates are between 1 and 100 feet per day.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Austin, TX","doi":"10.3133/sir20045225","collaboration":"In cooperation with the U.S. Air Force, Aeronautical Systems Center, Environmental Management Directorate, Wright-Patterson Air Force Base, Ohio","usgsCitation":"Houston, N.A., and Braun, C.L., 2004, Analyses and estimates of hydraulic conductivity from slug tests in alluvial aquifer underlying Air Force Plant 4 and Naval Air Station-Joint Reserve Base Carswell Field, Fort Worth, Texas: U.S. Geological Survey Scientific Investigations Report 2004-5225, Report: iv, 22 p.; 1 Plate: 26.00 x 24.00 inches, https://doi.org/10.3133/sir20045225.","productDescription":"Report: iv, 22 p.; 1 Plate: 26.00 x 24.00 inches","costCenters":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"links":[{"id":426218,"rank":3,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_73752.htm","linkFileType":{"id":5,"text":"html"}},{"id":6847,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2004/5225/","linkFileType":{"id":5,"text":"html"}},{"id":327719,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir20045225.JPG"}],"scale":"100000","country":"United States","state":"Texas","city":"Fort Worth","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -97.444444,\n              32.791667\n            ],\n            [\n              -97.444444,\n              32.752778\n            ],\n            [\n              -97.395833,\n              32.752778\n            ],\n            [\n              -97.395833,\n              32.791667\n            ],\n            [\n              -97.444444,\n              32.791667\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ad5e4b07f02db683887","contributors":{"authors":[{"text":"Houston, Natalie A. 0000-0002-6071-4545 nhouston@usgs.gov","orcid":"https://orcid.org/0000-0002-6071-4545","contributorId":1682,"corporation":false,"usgs":true,"family":"Houston","given":"Natalie","email":"nhouston@usgs.gov","middleInitial":"A.","affiliations":[{"id":583,"text":"Texas Water Science Center","active":true,"usgs":true}],"preferred":true,"id":282796,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Braun, Christopher L. 0000-0002-5540-2854 clbraun@usgs.gov","orcid":"https://orcid.org/0000-0002-5540-2854","contributorId":925,"corporation":false,"usgs":true,"family":"Braun","given":"Christopher","email":"clbraun@usgs.gov","middleInitial":"L.","affiliations":[{"id":48595,"text":"Oklahoma-Texas Water Science Center","active":true,"usgs":true}],"preferred":true,"id":282795,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

For example, the widespread discharge of nutrient-enriched submarine groundwater into an estuary or lagoon may contribute directly to the onset and duration of eutrophication, as well as the development of harmful algal/bacterial blooms. Most often, this submarine groundwater discharge (SGD) (defined here as a composite of meteoric, connate and sea water) occurs as hard-to-constrain diffuse seepage, rather than as focused discharge either through vent or collapse features. As a result, quantifying SGD rates has remained difficult for both oceanographers and hydrologists alike. This report describes an adaptation of an old tool, the Lee-type manual seepage meter, with a state-of-the-art electromagnetic flow meter that enables rapid, autonomous, bi-directional measurements of fluid exchange rates across the sediment/water interface. When such measurements are coupled and interpreted with surface and groundwater pressure, salinity and temperature data, as well as other complementary measurements such as excess watercolumn <sup>222</sup>Rn activities, then realistic groundwater/surface-water exchange rates can be obtained in dynamic coastal environments.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr20041369","usgsCitation":"Swarzenski, P.W., Charette, M., and Langevin, C., 2004, An autonomous, electromagnetic seepage meter to study coastal groundwater/surface-water exchange; 2004; OFR; 2004-1369;","productDescription":"4 p.","costCenters":[{"id":27821,"text":"Caribbean-Florida Water Science Center","active":true,"usgs":true}],"links":[{"id":362215,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2004/1369/ofr20041369.pdf","text":"Report","size":"1.04 MB","linkFileType":{"id":1,"text":"pdf"},"description":"OFR 2004-1369"},{"id":186180,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2004/1369/coverthb.jpg"}],"contact":"<p><a href=\"https://www.usgs.gov/centers/car-fl-water\" data-mce-href=\"https://www.usgs.gov/centers/car-fl-water\">Caribbean-Florida Water Science Center</a><br>U.S. Geological Survey<br>3321 College Avenue<br>Davie, FL 33314</p><p><a href=\"../contact\" data-mce-href=\"../contact\">Contact Pubs Warehouse</a></p>","tableOfContents":"<ul><li>Introduction</li><li>Principles of an EM Seepage Meter</li><li>Field Testing the EM Seepage Meters</li><li>Acknowledgments</li><li>References</li></ul>","publishedDate":"2004-09-01","noUsgsAuthors":false,"publicationDate":"2004-09-01","publicationStatus":"PW","scienceBaseUri":"4f4e4ad9e4b07f02db684db7","contributors":{"authors":[{"text":"Swarzenski, Peter W. 0000-0003-0116-0578 pswarzen@usgs.gov","orcid":"https://orcid.org/0000-0003-0116-0578","contributorId":1070,"corporation":false,"usgs":true,"family":"Swarzenski","given":"Peter","email":"pswarzen@usgs.gov","middleInitial":"W.","affiliations":[{"id":520,"text":"Pacific Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":282396,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Charette, Matt","contributorId":93986,"corporation":false,"usgs":true,"family":"Charette","given":"Matt","email":"","affiliations":[],"preferred":false,"id":282398,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Langevin, Christian D. 0000-0001-5610-9759","orcid":"https://orcid.org/0000-0001-5610-9759","contributorId":60297,"corporation":false,"usgs":true,"family":"Langevin","given":"Christian","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":282397,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The early results of this study raised broader concerns in Oakland County about the quality of groundwater in general and drinking water in particular. In response to these concerns, Oakland County worked with the USGS and the Center for Applied Environmental Research at the University of Michigan &ndash; Flint (CAER) to study distributions of arsenic, nitrate, and chloride in groundwater, with emphasis on sites where concentrations of these constituents exceeded the Maximum Contaminant Levels (MCL&rsquo;s) and Secondary Maximum Contaminant Levels (SMCL&rsquo;s) set by the U.S. Environmental Protection Agency (USEPA). The maps produced for this report are based on historical data compiled from MDEQ records. This fact sheet is a revision of USGS Fact Sheet 135-98, &ldquo;Arsenic, nitrate, and chloride in groundwater in Oakland County in Oakland County, Michigan&rdquo; (Aichele and others, 1998) to incorporate revisions to the USEPA MCL for arsenic.&nbsp;</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Lansing, MI","doi":"10.3133/fs20043120","usgsCitation":"Aichele, S., 2004, Arsenic, nitrate, and chloride in groundwater, Oakland County, Michigan: U.S. Geological Survey Fact Sheet 2004-3120, 6 p., https://doi.org/10.3133/fs20043120.","productDescription":"6 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":382,"text":"Michigan Water Science Center","active":true,"usgs":true}],"links":[{"id":120884,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/fs_2004_3120.jpg"},{"id":6425,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/fs/2004/3120/","linkFileType":{"id":5,"text":"html"}}],"scale":"24000","country":"United States","state":"Michigan","county":"Oakland County","geographicExtents":"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-83.4546,42.8798],[-83.2227,42.887],[-83.1025,42.8884],[-83.0986,42.801],[-83.0905,42.6238],[-83.0867,42.5355],[-83.0843,42.4463],[-83.3264,42.4416],[-83.4403,42.4393],[-83.553,42.4351],[-83.6669,42.4312],[-83.6733,42.5196],[-83.6863,42.7822],[-83.6902,42.871],[-83.5737,42.8744],[-83.4541,42.8766],[-83.4546,42.8798]]]},\"properties\":{\"name\":\"Oakland\",\"state\":\"MI\"}}]}\n","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abce4b07f02db672cbc","contributors":{"authors":[{"text":"Aichele, Stephen S. 0000-0002-3397-7921 saichele@usgs.gov","orcid":"https://orcid.org/0000-0002-3397-7921","contributorId":194508,"corporation":false,"usgs":true,"family":"Aichele","given":"Stephen S.","email":"saichele@usgs.gov","affiliations":[{"id":430,"text":"National Mapping Program","active":false,"usgs":true}],"preferred":false,"id":282478,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Much of the area is rural and rice cultivation is the primary agricultural activity. About 540 million gallons per day were withdrawn from the aquifer system in southwestern Louisiana in 2000. Potentiometric-surface maps of the aquifer system were created for June 2002 and January 2003 to determine where water-level declines occur due to seasonal ground-water withdrawals. During June 2002, water levels in the aquifer system were more than 40 feet below the National Geodetic Vertical Datum of 1929 (NGVD 29) in parts of Acadia, Calcasieu, Evangeline, and Jefferson Davis Parishes, in an area that generally coincides with rice-farming areas. During January 2003, water levels were more than 30 feet below NGVD 29 in these areas.</p><p>From June 2002 to January 2003, water levels generally recovered between 5 and 20 feet in the Chicot aquifer system in most of Acadia and Jefferson Davis Parishes, southeastern Calcasieu Parish, and southern Evangeline Parish, in an area that generally coincides with rice-farming areas. These water-level changes are representative of the areal extent and magnitude of typical seasonal water-level fluctuations that occur in the aquifer system in response to seasonal ground-water withdrawals for rice irrigation.</p><p>The presence of saltwater has been documented in the Chicot aquifer system beneath coastal parishes and in some areas where the aquifer system merges with the stratigraphically adjacent Atchafalaya aquifer. Data collected during the period 1943 to 2003 from 1,355 wells screened in the massive, upper, and \"200-foot\" sands of the Chicot aquifer system and the Atchafalaya aquifer were used to delineate areas having similar specific conductance values and determine areas where wells are affected by saltwater. Near the outcrop area, specific conductance values in the Chicot aquifer system generally are less than 150 µS/cm (microsiemens per centimeter at 25 degrees Celsius). Specific conductance values increase south and east of the outcrop area. Specific conductance values generally range from 151 to 500 µS/cm in rice-farming areas of northwestern Acadia Parish, southeastern Allen Parish, western Evangeline Parish, and northern and central Jefferson Davis Parish. Specific conductance values generally range from 501 to 1,000 µS/cm in most of the remaining rice-farming areas. Specific conductance values often exceed 1,000 µS/cm in an area along the border between Calcasieu and Jefferson Davis Parishes near Iowa, Louisiana, parts of northeastern Cameron Parish, an area of northwestern and central St. Landry Parish; parts of Vermilion Parish, and several areas along the eastern boundary of the study area where the Chicot aquifer system merges with the Atchafalaya aquifer. The maximum specific conductance value, 12,100 µS/cm, is from a well in Cameron Parish.</p><p>During 2000-03, specific conductance was measured in 521 water samples from 166 wells screened in the Chicot aquifer system or the Atchafalaya aquifer. Specific conductance values exceeded 1,000 µS/cm in water samples from wells in Calcasieu, Cameron, Jefferson Davis, St. Landry, St. Martin, St. Mary, and Vermilion Parishes. Specific conductance values exceeded 2,000 µS/cm in only two wells—an irrigation well located about 2 miles south of Iowa and a USGS observation well used to monitor saltwater encroachment in east-central Vermilion Parish. Specific conductance values increased steadily at one well, from 1,090 µS/cm in April 2000 to 2,860 µS/cm in April 2003. Nearby wells did not show similar increases.</p><p>Specific conductance was measured hourly during pumping at two irrigation wells between 2000 and 2003. Specific conductance values were greater than 1,000 µS/cm in both wells, indicating the presence of saltwater near the wells. Specific conductance values generally fluctuated about 150 µS/cm at both wells, but no long-term trends in the specific conductance were evident in either well.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20045212","usgsCitation":"Lovelace, J.K., Fontenot, J.W., and Frederick, C.P., 2004, Withdrawals, water levels, and specific conductance in the Chicot aquifer system in southwestern Louisiana, 2000-03: U.S. Geological Survey Scientific Investigations Report 2004-5212, 61 p., https://doi.org/10.3133/sir20045212.","productDescription":"61 p.","costCenters":[],"links":[{"id":185499,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":115734,"rank":2,"type":{"id":11,"text":"Document"},"url":"https://wise.er.usgs.gov/dp/pdfs/SIR_2004-5212.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"Louisiana","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"coordinates\": [\n          [\n            [\n              -91.44345652645958,\n              29.559038065926543\n            ],\n            [\n              -91.45442508072465,\n              29.911435800386656\n            ],\n            [\n              -91.67379616602312,\n              30.98935215679441\n            ],\n            [\n              -92.29900375912402,\n              30.98935215679441\n            ],\n            [\n              -92.55128050721702,\n              31.364726416221927\n            ],\n            [\n              -92.74871448398605,\n              31.289770689763913\n            ],\n            [\n              -93.637167379445,\n              31.26164691097344\n            ],\n            [\n              -93.6042617166505,\n              30.98935215679441\n            ],\n            [\n              -93.76879003062436,\n              30.518050248225705\n            ],\n            [\n              -93.79072713915447,\n              30.31941745040838\n            ],\n            [\n              -93.77975858488941,\n              30.158323843544082\n            ],\n            [\n              -93.95525545312833,\n              29.81631532382832\n            ],\n            [\n              -93.83460135621404,\n              29.654402715597158\n            ],\n            [\n              -93.47368763639625,\n              29.759199809794353\n            ],\n            [\n              -93.11172534565338,\n              29.72110452632333\n            ],\n            [\n              -92.66201462079137,\n              29.56857885310636\n            ],\n            [\n              -92.1684296788698,\n              29.492229452863953\n            ],\n            [\n              -91.76259317106737,\n              29.454033152035947\n            ],\n            [\n              -91.44345652645958,\n              29.559038065926543\n            ]\n          ]\n        ],\n        \"type\": \"Polygon\"\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49d9e4b07f02db5dfe53","contributors":{"authors":[{"text":"Lovelace, John K. 0000-0002-8532-2599 jlovelac@usgs.gov","orcid":"https://orcid.org/0000-0002-8532-2599","contributorId":999,"corporation":false,"usgs":true,"family":"Lovelace","given":"John","email":"jlovelac@usgs.gov","middleInitial":"K.","affiliations":[{"id":24708,"text":"Lower Mississippi-Gulf Water Science Center","active":true,"usgs":true},{"id":369,"text":"Louisiana Water Science Center","active":true,"usgs":true}],"preferred":true,"id":282439,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Fontenot, Jared W.","contributorId":26757,"corporation":false,"usgs":true,"family":"Fontenot","given":"Jared","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":282440,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Frederick, C.

The ground-water components included the upper and middle zones (undifferentiated) of the Trinity aquifer in the Hill Country and the unconfined part (recharge zone) and confined part (artesian zone) of the Edwards aquifer in the Balcones fault zone of the San Antonio region. The study was supplemented by information compiled from four ground-water-quality studies done during 1996–98.</p><p>Trinity aquifer waters are more mineralized and contain larger dissolved solids, sulfate, and chloride concentrations compared to Edwards aquifer waters. Greater variability in water chemistry in the Trinity aquifer likely reflects the more variable lithology of the host rock. Trace elements were widely detected, mostly at small concentrations. Median total nitrogen was larger in the Edwards aquifer than in the Trinity aquifer. Ammonia nitrogen was detected more frequently and at larger concentrations in the Trinity aquifer than in the Edwards aquifer. Although some nitrate nitrogen concentrations in the Edwards aquifer exceeded a U.S. Geological Survey national background threshold concentration, no concentrations exceeded the U.S. Environmental Protection Agency public drinking-water standard.</p><p>Synthetic organic compounds, such as pesticides and volatile organic compounds, were detected in the Edwards aquifer and less frequently in the Trinity aquifer, mostly at very small concentrations (less than 1 microgram per liter). These compounds were detected most frequently in urban unconfined Edwards aquifer samples. Atrazine and its breakdown product deethylatrazine were the most frequently detected pesticides, and trihalomethanes were the most frequently detected volatile organic compounds. Widespread detections of these compounds, although at small concentrations, indicate that anthropogenic activities affect ground-water quality.</p><p>Radon gas was detected throughout the Trinity aquifer but not throughout the Edwards aquifer. Fourteen samples from the Trinity aquifer and 10 samples from the Edwards aquifer exceeded a proposed U.S. Environmental Protection Agency public drinking-water standard. Sources of radon in the study&nbsp;area might be granitic sediments underlying the Trinity aquifer and igneous intrusions in and below the Edwards aquifer.</p><p>The presence of tritium in nearly all Edwards aquifer samples indicates that some component of sampled water is young (less than about 50 years), even for long flow paths in the confined zone. About one-half of the Trinity aquifer samples contained tritium, indicating that only part of the aquifer contains young water.</p><p>Hydrogen and oxygen isotopes of water provide indicators of recharge sources to the Trinity and Edwards aquifers. Most ground-water samples have a meteorological isotopic signature indicating recharge as direct infiltration of water with little residence time on the land surface. Isotopic data from some samples collected from the unconfined Edwards aquifer indicate the water has undergone evaporation.

Water-bearing strata were divided into four generalized hydrogeologic units: (1) fissured aquifers (including karst and non-karst limestone); (2) intergranular aquifers; (3) intergranular aquifers overlying fissured rock units; and (4) strata with local or limited ground-water resources. Approximately 49 percent of the municipal industrial parks are located in areas with local or limited ground-water resources, 29 percent overlie intergranular aquifers, 13 percent overlie fissured aquifers, and 9 percent overlie intergranular units that overlie fissured rock units. \r\n\r\n  \r\n\r\nHydrogeologic data for the generalized hydrogeologic units were compiled from published U.S. Geological Survey reports. Depths to ground water near industrial parks range from approximately 20 to 400 feet in the fissured aquifers, 6 to 65 feet in coastal intergranular aquifers, 3 to 30 feet in intergranular aquifers overlying fissured rock units, and 1 to 100 feet in strata with local or limited ground-water resources. Aquifer transmissivities near industrial parks range from approximately 100,000 feet squared per day in the fissured aquifers to less than 100 feet squared per day in the strata with local or limited ground-water resources. \r\n\r\n  \r\n\r\nWell construction data were compiled from published U.S. Geological Survey reports, drillers? logs, and unpublished reports. Specific capacity for wells near industrial parks ranges from approximately 100 gallons per minute per foot of drawdown in the fissured aquifer at Manati to approximately 0.1 gallon per minute per foot of drawdown in strata with local and limited ground-water resources at Bayamon. Reported well yields near industrial parks ranges from 2,800 gallons per minute in the intergranular aquifer at Santa Isabel to approximately 3 gallons per minute in strata with local and limited ground-water resources at Adjuntas. \r\n\r\n  \r\n\r\nHistorical ground-water-level data from U.S. Geological Survey observation wells were used to define ground-water levels trends in the vicinity of industrial parks. Areas showing ground-water level declines, and therefore possible aquifer over-development, are located in Barceloneta and Guayama. Rising ground-water levels were noted in the vicinity of industrial parks at Florida, Ponce, and Yauco. \r\nGround-water withdrawal data were compiled from site visits to the industrial facilities and from information provided by Puerto Rico Department of Natural and Environmental Resources. Total ground-water withdrawal at the municipal industrial parks was estimated to be 1.6 million gallons per day. Most withdrawals were from intergranular coastal aquifers, which accounted for about two thirds of the ground-water withdrawals. Municipal industrial parks with substantial ground-water withdrawals are located in Bayamon, Caguas, Humacao, and Ponce.","language":"ENGLISH","doi":"10.3133/sir20045029","usgsCitation":"Rodriguez, J.M., 2004, Assessment of ground-water withdrawals at municipal industrial parks in Puerto Rico, 2000 (Online only): U.S. Geological Survey Scientific Investigations Report 2004-5029, 73 p., https://doi.org/10.3133/sir20045029.","productDescription":"73 p.","onlineOnly":"Y","costCenters":[],"links":[{"id":6982,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/sir20045029/","linkFileType":{"id":5,"text":"html"}},{"id":186184,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"edition":"Online only","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4abae4b07f02db671fbd","contributors":{"authors":[{"text":"Rodriguez, Jose M. 0000-0002-4430-9929 jmrod@usgs.gov","orcid":"https://orcid.org/0000-0002-4430-9929","contributorId":1318,"corporation":false,"usgs":true,"family":"Rodriguez","given":"Jose","email":"jmrod@usgs.gov","middleInitial":"M.","affiliations":[{"id":156,"text":"Caribbean Water Science Center","active":true,"usgs":true}],"preferred":true,"id":282099,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

Simulation of surface-water integrated flow and transport in two-dimensions: SWIFT2D user's manual","docAbstract":"A numerical model for simulation of surface-water integrated flow and transport in two (horizontal-space) dimensions is documented. The model solves vertically integrated forms of the equations of mass and momentum conservation and solute transport equations for heat, salt, and constituent fluxes. An equation of state for salt balance directly couples solution of the hydrodynamic and transport equations to account for the horizontal density gradient effects of salt concentrations on flow. The model can be used to simulate the hydrodynamics, transport, and water quality of well-mixed bodies of water, such as estuaries, coastal seas, harbors, lakes, rivers, and inland waterways. The finite-difference model can be applied to geographical areas bounded by any combination of closed land or open water boundaries. The simulation program accounts for sources of internal discharges (such as tributary rivers or hydraulic outfalls), tidal flats, islands, dams, and movable flow barriers or sluices. Water-quality computations can treat reactive and (or) conservative constituents simultaneously. Input requirements include bathymetric and topographic data defining land-surface elevations, time-varying water level or flow conditions at open boundaries, and hydraulic coefficients. Optional input includes the geometry of hydraulic barriers and constituent concentrations at open boundaries. Time-dependent water level, flow, and constituent-concentration data are required for model calibration and verification. Model output consists of printed reports and digital files of numerical results in forms suitable for postprocessing by graphical software programs and (or) scientific visualization packages. The model is compatible with most mainframe, workstation, mini- and micro-computer operating systems and FORTRAN compilers. This report defines the mathematical formulation and computational features of the model, explains the solution technique and related model constraints, describes the model framework, documents the type and format of inputs required, and identifies the type and format of output available.","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Techniques and Methods Book 6, Chapter B","largerWorkSubtype":{"id":5,"text":"USGS Numbered Series"},"language":"ENGLISH","doi":"10.3133/tm6B1","isbn":"0607986174 ","usgsCitation":"Schaffranek, R.W., 2004, Section 1.
