Groundwater underlying the valley of Pinal Creek downstream from Globe, Arizona, has been contaminated by low-pH metal-enriched wastewater from copper mining and ore processing at Miami, Arizona. At present, the acidity and most of the dissolved metal content, except for Mn, of the wastewater is removed by reactions with carbonate and other solids in the alluvial aquifer before the neutralized contaminated water enters the creek channel and becomes surface flow. Where flow in the creek is perennial, Mn-bearing precipitates are formed in the stream bed and in some places in the subsurface. As an aid to understanding the processes involved and explaining the mineralogy of the precipitates, closely controlled laboratory redox titration experiments were performed on samples of surface flow and groundwater taken near the head of perennial flow in the creek.

The high content of dissolved Ca, Mg, Mn and COP2 species in the neutralized contaminated groundwater caused precipitation of some of the Mn as kutnahorite, (Mn, Mg)Ca(CO3)2, when the experimental system was held between pH 8.5 and 9.0 while CO2-free air was bubbled into the solution. Hausmannite and manganite also were precipitated, in somewhat lower amounts. When the concentrations of dissolved CO2 species in the groundwater sample were decreased before the experiment was started, the Mn precipitated was predominantly in the oxides hausmannite and manganite. In some of the experimental titrations clinoenstatite, (MgSiO3), was precipitated. After titrations were stopped the solutions and precipitates were allowed to stand, with limited access to the atmosphere, for several months. During this aging period the degree of oxidation of the precipitated Mn increased and in one precipitate from an experimental solution the Ca + Mn4+oxides todorokite and takanelite were identified. These oxides also have been identified in streambed precipitates. Some of these precipitates also gave X-ray diffraction reflections for kutnahorite.

Thermodynamic feasibilities of eight potential chemical reactions forming solid phases of interest were evaluated by calculating their respective reaction affinities attained during titration and aging. The results are in general agreement with the indications for the presence of these species given by X-ray and electron diffraction. The presence of carbonates in precipitated encrustations formed from groundwater below the land surface and their occurrence in manganese oxide crusts that precipitate from the creek water, also are predicted by these results.

The configuration of the southward-sloping water table under Yucca Mountain is dominated by an abrupt decline of 300 m over a distance of less than 2 km. This northeast-striking zone of large hydraulic gradient (of 0.15 or more) separates an area of moderate gradient (of about 0.015) to the north from an area of very small gradient (0.0001) to the south. The position of the large gradient does not correlate well with any evident geologic feature in the upper 0.5 km of the mountain, but we suggest that buried geologic features are present that can explain all the geohydrologic observations.

The three areas of differing hydraulic gradient under Yucca Mountain are parts of hydrogeologic domains that extend more than 70 km to the northeast. On a regional basis, the moderate and very small gradients generally correspond to areas underlain by exceptionally thick Tertiary volcanic sections and a highly transmissive Paleozoic carbonate aquifer, respectively. The regional large gradient and water-table decline are spatially associated with a contact in the Paleozoic rocks between clastic rocks and carbonates. This contact marks a large abrupt drop in the effective base of the hydrologic system because it is the upgradient boundary of the deep carbonate aquifer, which has a thickness of 5 km.

An aeromagnetic high follows the regional-scale domain of large gradient under northern Yucca Mountain from outcrops of a magnetite-bearing clastic confining unit to the east, indicating that the regional correlation of the steep water-table decline with the upgradient boundary of the deep carbonate aquifer may extend to Yucca Mountain. Five additional features may be related to an explanation for the large hydraulic gradient: (1) anomalously low heat flow has been measured deep in the volcanic section south of the water-table decline, suggesting underflow of cool water in the deep carbonate aquifer; (2) the lower tuff sequence, of 0.5–1 km in thickness, which underlies most of Yucca Mountain, is largely replaced in the volcanic section by lavas in the area of the large gradient; (3) an analysis of the hydrogeology of the tuff section under Yucca Mountain indicates that transmissivity in the tuffs increases to the south; (4) a northeast-trending gravity low is present immediately south of the water-table decline; (5) units in the lower part of the volcanic section are 50–100% thicker in the area of the gravity low than to the north and south. The abrupt stratigraphic thickening into the area of the gravity low indicates that the low represents a buried graben with its northern bounding fault centered beneath the abrupt water-table decline.

These geologic features of the zone of large gradient under Yucca Mountain suggest two possible hydrogeologic models. First, the northern bounding fault of the buried graben may provide a highly permeable pathway (a drain) through the brittle lavas in the lower part of the volcanic section under northern Yucca Mountain. The drain would allow flow from the tuff aquifer north of the decline to be captured by the deep carbonate aquifer, resulting in the heat-flow low, the abrupt water-table decline, and the transition to a very small hydraulic gradient. Alternatively, the northern bounding fault of the buried graben may be the effective northern limit of the tuff aquifer under Yucca Mountain because the permeability in the tuffs north of the fault may have been diminished by hydrothermal alteration. In this second model, the large gradient marks the point where the small southward flow of water through the altered volcanic rocks to the north abruptly drops into the tuff aquifer.

In either case, heads in the tuff aquifer in the area of very small gradient may be regulated partly by upward flow from the deep carbonate aquifer. This upward flow under southern Yucca Mountain is indicated by linear thermal highs along fault zones, by ground-water isotopic data suggesting inmixing of waters from the deep carbonate aquifer into the tuff aquifer, and by the upward hydraulic gradient found in a drill hole that penetrates the deep carbonate aquifer under southern Yucca Mountain.

Selenium concentrations in samples of fish and bird eggs support these conclusions at a majority of these areas.

Porosity of welded tuff from Snowshoe Mountain, Colorado, was characterized by mercury intrusion porosimetry (MIP), nitrogen sorption porosimetry, ethylene glycol monoethyl ether (EGME) gas phase sorption and epifluorescence optical microscopy. Crushed tuff of two particle-size fractions (1-0.3 mm and less than 0.212 mm), sawed sections of whole rock and crushed tuff that had been reacted with 0.1 N hydrochloric acid were examined. Average MIP pore diameter values were in the range of 0.01–0.02μm. Intrusion volume was greatest for tuff reacted with 0.1 N hydrochloric acid and least for sawed tuff. Cut rock had the smallest porosity (4.72%) and crushed tuff reacted in hydrochloric acid had the largest porosity (6.56%). Mean pore diameters from nitrogen sorption measurements were 0.0075–0.0187 μm. Nitrogen adsorption pore volumes (from 0.005 to 0.013 cm3/g) and porosity values (from 1.34 to 3.21%) were less than the corresponding values obtained by MIP. More than half of the total tuff pore volume was associated with pore diameters < 0.05μm. Vapor sorption of EGME demonstrated that tuff pores contain a clay-like material. Epifluorescence microscopy indicated that connected porosity is heterogeneously distributed within the tuff matix; mineral grains had little porosity. Tuff porosity may have important consequences for contaminant disposal in this host rock.

An example of the pollution caused by the discharge of DNAPLs is found at the Picatinny Arsenal, New Jersey, where trichloroethylene (TCE) has been discharged directly into the unsaturated zone. This discharge has resulted in the formation of a plume of TCE-contaminated water in the aquifer downgradient of the discharge. A zone of dark-colored groundwater containing a high dissolved organic C content has been found near the point of discharge of the TCE. The colored-water plume extends from the point of discharge at least 30 m (100 feet) downgradient. Fulvic acids isolated from the colored-waters plume, from water from a background well that has not been affected by the discharge of chlorinated solvents, and from soil pore water collected in a lysimeter installed at an uncontaminated site upgradient of the study area have been compared. Nuclear magnetic resonance spectra of the fulvic acids from the colored waters and from the lysimeter are very similar, but are markedly different from the nuclear magnetic resonance spectrum of the fulvic acid from the background well. The three-dimensional fluorescence spectrum and the DOC fractionation profile of the colored groundwater and the soil pore water are very similar to each other, but quite different from those of the background water. It is proposed from these observations that this colored water is soil pore water that has been displaced by a separate DNAPL liquid phase downward to the saturated zone.","language":"English","publisher":"ACSESS","doi":"10.2134/jeq1994.00472425002300040025x","issn":"00472425","usgsCitation":"Wershaw, R., Aiken, G., Imbrigiotta, T., and Goldberg, M.C., 1994, Displacement of soil pore water by trichloroethylene: Journal of Environmental Quality, v. 23, no. 4, p. 792-798, https://doi.org/10.2134/jeq1994.00472425002300040025x.","productDescription":"7 p.","startPage":"792","endPage":"798","costCenters":[{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":228667,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"23","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a0220e4b0c8380cd4fecd","contributors":{"authors":[{"text":"Wershaw, R.L.","contributorId":62223,"corporation":false,"usgs":true,"family":"Wershaw","given":"R.L.","affiliations":[],"preferred":false,"id":377224,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Aiken, G.

Theis; each is augmented with a discussion that explains why he wrote the paper, attempts to discern why he did not publish the paper, and amplifies the information with reference material not included by Theis. \r\n\r\n'A Primer on Anisotropy' was written in the early 1970's to provide practicing hydrogeologists of the day with a method of analyzing ground-water problems involving anisotropic hydraulic-conductivity distribution without using tensor mathematics. The equations were developed for horizontal flow through dipping beds with differing conductivities parallel and perpendicular to the bedding and for flow through dipping beds having three different hydraulic conductivities, one perpendicular to the bedding and two others parallel to the bedding, at an angle to the strike of the beds. \r\n\r\nAlthough most colleagues who reviewed the primer in the early 1970's encouraged its publication enthusiastically, at least one suggested the addition of some examples in which the method would be demonstrated. Handwritten notes from Theis' files indicate that he may have worked on some examples and possibly other additions to the paper. The comments by Charles A. Appel include some examples of the primer's use and augment the presentation with references to relevant published papers, both those available to Theis but not cited by him, and subsequent publications. \r\n\r\n'Aquifers, Ground-Water Bodies, and Hydrophers' was written in the early 1980's as an attempt to clarify the semantic and conceptual confusion in the use of the term aquifer, applied by some investigators to the saturated part of a permeable formation and by others to the entire permeable formation. The physical distinction between the aquifer and the ground-water body is emphasized, and the term hydropher is proposed to describe the saturated part of a permeable formation. Theis' interest in and familiarity with the French literature on ground water was the basis for a discussion of the French usage, which eschews the term aquifer. The analysis and critique of Theis' palzler explains the 1835 paper from which aquifer was reportedly derived, and provides further justification for the term hydropher. \r\n\r\nTheis' more important contributions to ground-water hydrology were outgrowths of his solutions to small local water problems based on field investigations. The biographical sketch, drawing extensively from a partial autobiography that Theis had dictated, reveals both the reasons for and the intellectual processes that led to his development of the nonequilibrium concept of ground-water hydraulics.

Water resources data for the 1993 water year for Massachusetts and Rhode Island consists of records of stage, discharge, and water quality of streams; contents of lakes and reservoirs; and ground-water levels. This report contains discharge records for 77 gaging stations, month end contents of five lakes and reservoirs, water quality at 10 gaging stations, and water levels for 137 observation wells. Data also are included for 59 low-flow partial-record stations. Miscellaneous hydrologic data were collected at various sites that were not a part of the systematic data-collection program and are published as miscellaneous discharge measurements and quality of ground water. A few pertinent stations in bordering States are also included in this report. These data represent that part of the National Water Data System operated by the U.S. Geological Survey and cooperating State and Federal agencies in Massachusetts and Rhode Island.

Operation of the Garrison Diversion Unit may have some affect on the hydrology of the James River in North Dakota and South Dakota. The Garrison Diversion Unit Monthly Operations Model was developed to analyze a wide range of streamflow conditions that could occur in the James River Basin. The purpose of this study was to compute monthly streamflows that are required as input to the model.

Historic streamflow data were complied and record extension methods were used, when necessary, to compute monthly streamflow for 1983-91 for 15 gaging stations on the James River in North Dakota and South Dakota. The record extension methods used include Maintenance of Variance Extension Type 1, Ordinary Least Squares, and drainage-area ratio.

In addition to the historic streamflow, synthesized unregulated streamflow was computed for the 15 gaging stations on the James River for 1983-91 by eliminating the effects of Jamestown Reservoir, Pipestem Reservoir, Sand Lake National Wildlife Refuge, consumptive surface-water withdrawals, and wastewater withdrawals. Maintenance of Variance Extension Type 1, Ordinary Least Squares regression, water-balance procedures, and drainage-area ratio method were used to compute the unregulated streamflows.

Water and streambed-sediment samples were collected on March 9 and 10,1987 from one site upstream and three sites downstream of the discharge from a municipal wastewater-treatment plant on Rowlett Creek near Dallas, Texas. To extract and separate organic compounds, purgeand-trap, closed-loop stripping, and pH-adjusted solvent extraction methods were used for water samples; and a Soxhlet-solvent extraction method was used for streambed sediment. These methods were combined with gas chromatography/mass spectrometry to identify organic compounds in Rowlett Creek. Results from this study confirm the persistence of many organic compounds in water as far as 13.5 kilometers downstream of the wastewater discharge. These include: (1) the volatile organic compounds chloroform, 1,2-dichlorobenzene, 1,4-dichlorobenzene, tetrachloroethene, and trichloroethene; (2) several linear alkylbenzene compounds, octyl phenol, and a tetramethylbutyl phenol isomer that are related to detergent use; (3) 9-phenyl-9H-carbazole, a compound related to coal tars and coal combustion residues; and (4) caffeine. The only compound present in water in concentrations greater than U.S. Environmental Protection Agency maximum contaminant levels for drinking water was tetrachloroethene (6.0 micrograms per liter) in a sample collected 13.5 kilometers downstream from the waste water discharge. Compounds identified from the streambed-sediment samples include a xylene isomer at 7.7 kilometers downstream and chrysene, fluoranthene, pyrene, and a xylene isomer at 13.5 kilometers downstream from the wastewater discharge.

\n

Comparison of instantaneous flux values of selected organic compounds in water from downstream sites indicates: (1) the formation of chloroform in the stream following the discharge of the treated effluent, and that (2) instream biodegradation may be decreasing concentrations of linear alkylbenzene compounds in water. The relative persistence of many of the selected organic compounds in Rowlett Creek downstream from the municipal wastewater-treatment plant indicates that they could be transported into Lake Ray Hubbard, a source of municipal water supply.

During the first 15 years of the program (1978-92), 25 regional aquifer systems, including the most heavily pumped aquifers in the Nation, were intensively studied. As of mid-1992, 18 of the regional aquifer studies are completed or nearly so; 7 of the regional aquifer studies are ongoing, and compilation of a national ground-water atlas is in progress. \r\n\r\nThis report summarizes the status of each RASA study and briefly describes the hydrology of the 25 regional aquifer systems. Important study results and examples of applications of study results are presented for some of the completed RASA investigations. \r\n\r\nThe major contributions of the RASA Program are (1) assembly of data from numerous local studies and long-time data collections into systematic regional data bases; (2) comprehensive descriptions of the geologic, hydrologic, and geochemical characteristics of the regional aquifer systems; and (3) an understanding of how the regional ground-water-flow systems function under natural (predevelopment) and current (developed) conditions. To provide the comprehensive system descriptions, many of the RASA studies present, for the first time, maps depicting the hydrogeologic frameworks, water chemistry, potentiometric surfaces, and other aspects of entire regional aquifer systems. \r\n\r\nTo provide an understanding of how the flow systems function, several of the completed RASA studies provide, for the first time, hydrologic budgets for both predevelopment and developed conditions. The results of the RASA Program are contained in nearly 900 reports published by the USGS, as well as various State and local agencies, and in articles published in scientific journals.

The contaminated aquifer is a narrow layer of unconsolidated alluvium along Miami Wash and Pinal Creek. The alluvium overlies basin fill, which extends throughout most of the Pinal Creek basin. The alluvium and basin fill compose the primary aquifer in the basin. Horizontal hydraulic con- ductivities were estimated at about 200 meters per day in the alluvium, and average linear ground- water flow velocities are about 5 meters per day. Water levels in the aquifer respond rapidly to periods of extended runoff in the basin and variable rates of ground-water pumping. Fluctuations of as much as 2.5 meters in 6 months have been measured. Ground-water levels were near record highs during spring 1985 and declined as much as 13 meters by spring 1989. Measured hydraulic gradients indicate that flow is generally upward from the basin fill to the alluvium. From 1980 to 1984, seepage of 155 liters per second from Webster Lake and 279 liters per second streamflow infiltration were estimated to be the two largest sources of inflow to the regional aquifer. Major outflows from the aquifer were 166 liters per second of pumpage and 240 liters per second of natural ground-water discharge to Pinal Creek.","language":"English","publisher":"U.S. Geological

Thick unsaturated zones in arid regions increasingly are being sought for the burial of radioactive and other hazardous wastes. Estimating percolation rates of water from precipitation at proposed burial sites is important for site assessment. Chloride profiles in unsaturated sediments are used to show differences and similarities in the rates of percolation at two sites in the Mojave Desert of southern Nevada and southeastern California; the first is an existing burial site for low-level radioactive waste in the Amargosa Desert, and the second is a proposed waste-burial site in Ward Valley. The Mojave Desert is one of the most arid regions of the United States.

Chloride concentrations in pore water of unsaturated sediments peak between depths of 2 and 3 meters at both the Amargosa Desert and Ward Valley, sites; maximum chloride concentration is 9,000 milligrams per liter at the Amargosa Desert site and 15,000 milligrams per liter at the Ward Valley, site. Below a depth of 10 meters, however, chloride concentrations at the Amargosa Desert site decrease to less than 50 milligrams per liter, whereas concentrations at the Ward Valley site are greater than 2,300 milligrams per liter. Estimated age of water at a depth of 10 meters at both sites is between 16,000 and 33,000 years. Below a depth of 10 meters, estimated age of water in the sediments at the Ward Valley site is considerably older than at the Amargosa Desert site because of the greater chloride concentrations at the Ward Valley site.

The dilute chloride concentrations in the pore water below a depth of 10 meters at the Amargosa Desert site could indicate that the sediments were flushed with water in the past. The climate in the region was wetter and cooler from about 30,000 to 18,000 years ago. Perhaps increased precipitation or more frequent flooding of the Amargosa River resulted in deep percolation at the site. Downward percolation of water since that time seems limited to the upper 10 meters.

The downward percolation rate of water below a depth of 10 meters at the Amargosa Desert site, as estimated from chloride concentrations, is 0.2 centimeters per year; however, the rate is not representative of present conditions as measured water-potential and vapor-density, gradients indicate upward water flow. The rate may be representative of a period during the Pleistocene when the climate was wetter and cooler. Estimated percolation rates below a depth of 10 meters at the Ward Valley site are on the order of 3 to 5 centimeters per 1,000 years, also reflecting flow conditions during the Pleistocene.

National Water-Quality Assessment Program study units throughout the conterminous United States. The proportions of nitrogen originating from fertilizer, manure, atmospheric deposition, sewage, and industrial sources were found to vary with climate, hydrologic conditions, land use, population, and physiography. Fertilizer sources of nitrogen are proportionally greater in agricultural areas of the West and the Midwest than in other parts of the Nation. Animal manure contributes large proportions of nitrogen in the South and parts of the Northeast. Atmospheric deposition of nitrogen is generally greatest in areas of greatest precipitation, such as the Northeast. Point sources (sewage and industrial) generally are predominant in watersheds near cities, where they may account for large proportions of the nitrogen in streams. The transport of nitrogen in streams increases as amounts of precipitation and runoff increase and is greatest in the Northeastern United States. Because no single nonpoint nitrogen source is dominant everywhere, approaches to control nitrogen must vary throughout the Nation. Watershed-based approaches to understanding nonpoint and point sources of contamination, as used by the National Water-Quality Assessment Program, will aid water-quality and environmental managers to devise methods to reduce nitrogen pollution.","language":"ENGLISH","publisher":"Geological Survey (U.S.)","doi":"10.3133/wri944001","usgsCitation":"Puckett, L., 1994, Nonpoint and Point Sources of Nitrogen in Major Watersheds of the United States (Revised Mar 1994): U.S. Geological Survey Water-Resources Investigations Report 94-4001, iii, 9 p., https://doi.org/10.3133/wri944001.","productDescription":"iii, 9 p.","costCenters":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"links":[{"id":126693,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/wri/1994/4001/report-thumb.jpg"},{"id":11654,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/wri/wri944001/","linkFileType":{"id":5,"text":"html"}},{"id":58089,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/1994/4001/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"edition":"Revised Mar 1994","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4af3e4b07f02db691aed","contributors":{"authors":[{"text":"Puckett, Larry J. lpuckett@usgs.gov","contributorId":31739,"corporation":false,"usgs":true,"family":"Puckett","given":"Larry J.","email":"lpuckett@usgs.gov","affiliations":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"preferred":false,"id":201183,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}} ,{"id":4493,"text":"cir1120D - 1994 - Major ions, nutrients, and trace elements in the Mississippi River near Thebes, Illinois, July through September 1993","interactions":[],"lastModifiedDate":"2019-12-08T13:50:45","indexId":"cir1120D","displayToPublicDate":"1994-01-01T00:00:00","publicationYear":"1994","noYear":false,"publicationType":{"id":18,"text":"Report"},"publicationSubtype":{"id":5,"text":"USGS Numbered Series"},"seriesTitle":{"id":307,"text":"Circular","code":"CIR","onlineIssn":"2330-5703","printIssn":"1067-084X","active":true,"publicationSubtype":{"id":5}},"seriesNumber":"1120","chapter":"D","title":"Major ions, nutrients, and trace elements in the Mississippi River near Thebes, Illinois, July through September 1993","docAbstract":"

Extensive flooding in the upper Mississippi River Basin during summer 1993 had a significant effect on the water quality of the Mississippi River. To evaluate the change in temporal distribution and transport of dissolved constituents in the Mississippi River, six water samples were collected by a discharge-weighted method from July through September 1993 near Thebes, Illinois. Sampling at this location provided water-quality information from the upper Mississippi, the Missouri, and the Illinois River Basins.

Dissolved major constituents that were analyzed in each of the samples included bicarbonate, calcium (Ca), carbonate (C03), chloride (Cl), dissolved organic carbon, magnesium (Mg), potassium (K), silica NOD, sodium (Na), and sulfate (S04). Dissolved nutrients included ammonium ion (NH4), nitrate (N03), nitrite (N02), and orthophosphate (P04) . Dissolved trace elements included aluminum (Al), arsenic (As), barium (Ba), boron (B), beryllium (Be), bromide (Br), cadmium (Cd), chromium (Cr), cobalt, (Co), copper (Cu), fluoride (F), iron (Fe), lead, lithium (Li), manganese (Mn), mercury (Hg), molybdenum (Mo), nickel (Ni), strontium (Sr), thallium, uranium (U), vanadium (V), and zinc (Zn). Other physical properties of water that were measured included specific conductance, pH and suspended-sediment concentration (particle size, less than 63 micrometers).

Results of this study indicated that large quantities of dissolved constituents were transported through the river system. Generally, pH, alkalinity, and specific conductance and the concentrations of B, Br, Ca, Cl, Cr, K, Li, Mg, Mo, Na, S04, Sr, U, and V increased as water discharge decreased, while concentrations of F, Hg, and suspended sediment sharply decreased as water discharge decreased after the crest of the flood. Concentrations of other constituents, such as Al, As, Ba, Be, Co, Cu, Ni, N03, N02, NH4, P04, and Si02, varied with time as discharge decreased after the crest of the flood.

For most constituents, the load transported during floods generally is much greater than that transported during low-flow conditions. How ever, for Cd, Cr, Fe, Mn, V, and Zn, loads increased substantially as water discharge decreased after the crest of the flood.

aquifers in the midcontinental United States, 1991","docAbstract":"

The occurrence and distribution of selected herbicides, atrazine metabolites, and nitrate were determined for near-surface aquifers (within 50 feet of land surface) in the corn- and soybean-producing region of the midcontinental United States. The study region included all or parts of Illinois, Indiana, Iowa, Kansas, Michigan, Minnesota, Missouri, Nebraska, North Dakota, Ohio, South Dakota, and Wisconsin. Water samples were collected during the spring and summer of 1991 from 303 wells completed in near-surface unconsolidated and near-surface bedrock aquifers. At least one herbicide or atrazine metabolite was detected in 24 percent of 579 water samples analyzed for herbicides, based on a reporting limit of 0.05 microgram per liter. However, no herbicide concentration exceeded the U.S. Environmental Protection Agency's maximum contaminant levels or health advisory levels for drinking water. The most frequently detected herbicide compound was desethylatrazine, an atrazine metabolite (18.1 percent), followed by atrazine (17.4 percent); deisopropylatrazine, an atrazine metabolite (5.7 percent); prometon (5.0 percent); metolachlor (2.7 percent); alachlor (1.7 percent); simazine (1.0 percent); metribuzin (1.0 percent); and cyanazine (0.7 percent). The herbicides ametryn, prometryn, propazine, and terbutryn were not detected during this study. Nitrate concentrations equal to or greater than 3.0 milligrams per liter (excess nitrate) were detected in 29 percent of the 599 nitrate analyses, and ammonium concentrations equal to or greater than 0.01 milligram per liter were detected in 78 percent of the 584 ammonium analyses. Nitrate concentrations equal to or greater than the U.S. Environmental Protection Agency's maximum contaminant level for drinking water of 10 milligrams per liter were found in 6 percent of the samples.

\n

The frequency of herbicide detection was, in part, affected by the analytical method's reporting limit. Results from this study show that the frequency of atrazine detection increases as the reporting limit decreases. Herbicide metabolite concentrations are critical to understanding the detection of herbicide residues. The frequency of detection of atrazine residue (atrazine + desethylatrazine + deisopropylatrazine) was 22.1 percent, which was more than the frequency of detection of atrazine alone (17.4 percent).

\n

Prometon was detected more frequently than every other herbicide except atrazine. The prometon appears to be derived from areas of nonagricultural land use, such as golf courses and residential areas. Herbicides and excess nitrate were both rarely detected in the eastern part of the study region, even though this is an area of intense herbicide and nitrogen-fertilizer use.

\n

Hydrogeologic factors, land use, agricultural practices, local features, and water chemistry were analyzed for possible relation to herbicide and excess-nitrate detections. Herbicides and excess nitrate were detected more frequently in near-surface unconsolidated aquifers than in nearsurface bedrock aquifers. The depth to the top of the aquifer was inversely related to the frequency of detection of herbicides and excess nitrate. The proximity of streams to sampled wells also affected the frequency of herbicide detection. Significant seasonal differences were determined for the frequency of herbicide detection, but not for the frequency of excess nitrate.

Scope of the Long Island-New Jersey Coastal Drainages Study-Unit Investigation

In 1991, the U.S. Geological Survey (USGS) began a National Water-Quality Assessment (NAWQA) Program to document the status of and trends in quality of a large representative part of the Nation's water resources and to provide a sound scientific understanding of the primary natural and human factors that affect the quality of these resources. The program is designed to produce long-term, consistent water-quality information that will be useful to policymakers and managers at national, State, and local levels.

Investigations of 60 hydrologic systems (study units), which include parts of most major river basins and aquifer systems in the United States, are the building blocks of NAWQA. A framework has been established to ensure nationwide consistency in the approach to each study--in field and laboratory methods, in water-quality measurements, and in the supporting data requirements. Twenty studies were started in 1991, 20 more have begun in 1994, and 20 are scheduled to begin in 1997.

A major design feature of the program that will facilitate integration of water-quality information at national, regional, and local scales is coordination between the individual study-unit teams and the national synthesis effort at all stages of the investigations. Thus, results that relate to various topics addressed in the study-unit investigations will be integrated smoothly into NAWQA's national synthesis component. Teams have been developed to address the following topics of national importance: pesticides, nutrients, and volatile organic compounds. These teams are investigating the specific issues by means of comparative studies of a large set of hydrologic systems distributed over a wide range of environmental settings found in the 60 study-units.

The information below summarizes the goals and scope of the NAWQA Program and the Long Island-New Jersey Coastal Drainages study, which began in 1994.

Of particular interest was the presence of agricultural chemicals and petroleum-derived hydrocarbons that might have been associated with brines that formerly were disposed into unlined ponds. \r\n\r\nRandom sampling of ground water was done within a framework of discrete land-use areas (irrigated cropland, petroleum-production land containing former brine-disposal ponds, and undeveloped rangeland) of 3-10 square miles. Although true baseline water-quality conditions probably are rare, in this region they are represented most closely by ground water in areas of undeveloped rangeland. The sampling design enabled statistical hypothesis testing, using nonparametric procedures, of the effects of land use, unsaturated-zone lithology, and type of well sampled. \r\n\r\nResults indicate that regional ground-water quality has been affected by prevailing land-use activities, as shown by increased concentrations of several inorganic constituents. Ground water beneath irrigated cropland was characterized by significantly larger concentrations of hardness, alkalinity, calcium, magnesium, potassium, fluofide, and nitrite plus nitrate than was water beneath undeveloped rangeland. Few nondegraded pesticides were detected in the aquifer, probably because of degradation and sorption. Atrazine was the most common, but only in small concentrations. round water beneath petroleum-production land was characterized by significantly larger concentrations of hardness, alkalinity, dissolved solids, sodium, and chloride than was water beneath undeveloped rangeland. Nonpoint-source contamination by oil-derived hydrocarbons was not discernible. The occurrences of trace organic compounds were similar between petroleum-production land and undeveloped rangeland, which indicates a natural origin for these compounds. \r\n\r\nThe unsaturated zone in the study area is lithologically heterogeneous and contains substantial amounts of clay that inhibit the downward movement of water and solutes. Within the aquifer, the rate of lateral regional flow and solute transport is slow enough so that the ground-water quality reflects overlying land use in discrete areas of several square miles, but it is still sufficiently rapid so that the type of well sampled is not important in regional characterizations of water quality beneath irrigated cropland; the seasonal pumping of irrigation wells does not appear to divert regional flow enough to cause substantial local anomalies of more mineralized ground water.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/wsp2381C","usgsCitation":"Helgesen, J.O., Stullken, L.E., and Rutledge, A.T., 1994, Assessment of nonpoint-source contamination of the High Plains Aquifer in south-central Kansas, 1987: U.S. Geological Survey Water Supply Paper 2381, v, 51 p. , https://doi.org/10.3133/wsp2381C.","productDescription":"v, 51 p.

In 1991, the U.S. Geological Survey (USGS) began its National Water-Quality Assessment (NAWQA ) program to (1) document the quality of a large, representative part of the Nation's water resources; (2) define water-quality trends; and (3) identify major factors that affect water quality. In addressing these goals, the program will produce information that will be useful to water policy makers and managers at National, State, and local levels.

Studies of 60 hydrologic systems that include parts of most major river and aquifer systems form the building blocks of the NAWQA program. Study units range in size from about 1,000 mi ² (square miles) to more than 60,000 mi² and represent 60 to 70 percent of the Nation's water use and population served by public water supply. The first 20 studies were begun in 1991; 20 more were begun in 1994, and the remaining 20 are to begin in 1997.
