In this report, we present acquisition parameters, data, and interpretations of seismic images that were acquired in the OU-1 area of GAFB during July 1999 (Fig. 2). GAFB is scheduled for conversion to civilian use, however, during its years as an Air Force base, trichlorethylene (TCE) was apparently introduced into the subsurface as a result of spills during normal aircraft maintenance operations. To comply with congressional directives, TCE contaminant removal has been ongoing since the early-tomid 1990s. However, only a small percentage of the TCE believed to have been introduced into the subsurface has been recovered, due largely to difficulty in locating the TCE within the subsurface.\n\nBecause TCE migrates within the subsurface by ground water movement, attempts to locate the TCE contaminants in the subsurface have employed an array of ground-water monitoring and extraction wells. These wells primarily sample within a shallow-depth (~40 m) aquifer system. Cores obtained from the monitoring and extraction wells indicate that the aquifer, which is composed of sand and gravel channels, is bounded by aquitards composed largely of clay and other fine-grained sediments. Based on well logs, the aquifer is about 3 to 5 m thick along the seismic profiles. A more thorough understanding of the lateral variations in the depth and thickness of the aquifer system may be a key to finding and removing the remaining TCE. However, due to its complex depositional and tectonic history, the structural and stratigraphic sequences are not easily characterized. An indication of the complex nature of the structure and stratigraphy is the appreciable variation in stratigraphic sequences observed in some monitoring wells that are only a few tens of meters apart.\n\nTo better characterize the shallow (upper 100 m) stratigraphy beneath GAFB, the US Environmental Protection Agency (USEPA) contracted the US Geological Survey (USGS) to acquire three seismic reflection/refraction profiles within an area known as Operational Unit #1 (OU-1). The principal objective of the seismic survey was to laterally characterize the subsurface with respect to structure and stratigraphy. In particular, we desired to (1) laterally “map” stratigraphic units (particularly aquifer layers) that were previously identified in monitoring wells within the OU-1 area and (2) identify structures, such as faults and folds, that affect the movement of ground water. Knowledge of lateral variations in stratigraphic units and structures that may affect those units is useful in constructing ground-water flow models, which aid in identifying possible TCE migration paths within the subsurface. Stratigraphic and structural characterization may also be useful in identifying surface locations and target depths for future wells (Catchings et al., 1996). Proper siting of wells is important because a welldefined aquifer is apparently not present in all locations at GAFB, as indicated by lithologic logs from existing wells (Montgomery Watson, 1995). Proper depth placement of monitoring and extraction wells is important because wells that are too shallow will not sample within the aquifer, and wells that are too deep risk puncturing the aquitard and allowing contaminants to flow to deeper levels.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr0160","usgsCitation":"Catchings, R.D., Gandhok, G., and Goldman, M.R., 2001, Stratigraphic and structural characterization of the OU-1 area at the former George Air Force Base, Adelanto, southern California: U.S. Geological Survey Open-File Report 2001-60, 55 p., https://doi.org/10.3133/ofr0160.","productDescription":"55 p.","numberOfPages":"55","costCenters":[{"id":237,"text":"Earthquake Science Center","active":true,"usgs":true}],"links":[{"id":161032,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/ofr0160.jpg"},{"id":281999,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0060/pdf/of01-60.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":2795,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/0060/","linkFileType":{"id":5,"text":"html"}},{"id":405931,"rank":4,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_42708.htm","linkFileType":{"id":5,"text":"html"}}],"country":"United States","state":"California","city":"Adelanto","otherGeospatial":"George Air Force Base","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -117.399,\n              34.554\n            ],\n            [\n              -117.3440,\n              34.554\n            ],\n            [\n              -117.3440,\n              34.612\n            ],\n            [\n              -117.399,\n              34.612\n            ],\n            [\n              -117.399,\n              34.554\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b27e4b07f02db6b0f2c","contributors":{"authors":[{"text":"Catchings, R.

Dissolved nickel and predominant ligands (represented by dissolved organic carbon, and sulfides) were the solutes of primary interest, although a variety of ancillary measurements were also performed to provide a framework for interpretation. Results described herein integrate information needs identified by the State Water Resources Control Board and local stakeholders with fundamental research associated with the U.S. Geological Survey Toxic Substances Hydrology Program. Dissolved-Ni concentrations in the bottom water over the three sampling dates ranged from 34 to 43 nanomoles per liter. Dissolved-macronutrient concentrations in the bottom water were consistently higher (frequently by orders of magnitude) than surface-water determinations reported for similar times and locations (Regional Monitoring Program, 2001). This is consistent with measured positive benthic fluxes for the macronutrients. Benthic-flux estimates for dissolved nickel from core-incubations, when areally averaged over the South Bay, were significant (that is, of equivalent or greater order of magnitude) relative to previously reported freshwater point and non-point sources. This observation is consistent with previous determinations for other metals, and with the potential remobilization of sediment-associated metals that have been ubiquitously distributed in the South Bay. Similar to dissolved-nickel results, benthic flux of macronutrients was also consistently significant relative to surface-water inputs. These results add to a growing body of knowledge that strongly suggests a need to consider contaminant transport across the sediment-water interface when establishing future management strategies for the watershed.</p>","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr0189","usgsCitation":"Topping, B., Kuwabara, J., Parcheso, F., Hager, S., Arnsberg, A., and Murphy, F., 2001, Benthic flux of dissolved nickel into the water column of south San Francisco Bay: U.S. Geological Survey Open-File Report 2001-89, 50 p., https://doi.org/10.3133/ofr0189.","productDescription":"50 p.","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true},{"id":5079,"text":"Pacific Regional Director's Office","active":true,"usgs":true}],"links":[{"id":2845,"rank":2,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/ofr01-089/index.html","linkFileType":{"id":5,"text":"html"}},{"id":160776,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"San Francisco Bay","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -123.035888671875,\n              37.36142550190517\n            ],\n            [\n              -121.84936523437499,\n              37.36142550190517\n            ],\n            [\n              -121.84936523437499,\n              38.1777509666256\n            ],\n            [\n              -123.035888671875,\n              38.1777509666256\n            ],\n            [\n              -123.035888671875,\n              37.36142550190517\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a53e4b07f02db62b5cd","contributors":{"authors":[{"text":"Topping, B.R.","contributorId":97541,"corporation":false,"usgs":true,"family":"Topping","given":"B.R.","email":"","affiliations":[],"preferred":false,"id":205455,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kuwabara, J.S.","contributorId":57905,"corporation":false,"usgs":true,"family":"Kuwabara","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":205453,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Parcheso, Francis 0000-0002-9471-7787 parchaso@usgs.gov","orcid":"https://orcid.org/0000-0002-9471-7787","contributorId":2590,"corporation":false,"usgs":true,"family":"Parcheso","given":"Francis","email":"parchaso@usgs.gov","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":false,"id":205450,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Hager, S.W.","contributorId":51746,"corporation":false,"usgs":true,"family":"Hager","given":"S.W.","email":"","affiliations":[],"preferred":false,"id":205452,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Arnsberg, A.J.","contributorId":92715,"corporation":false,"usgs":true,"family":"Arnsberg","given":"A.J.","email":"","affiliations":[],"preferred":false,"id":205454,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Murphy, Fred fmurphy@usgs.gov","contributorId":4572,"corporation":false,"usgs":true,"family":"Murphy","given":"Fred","email":"fmurphy@usgs.gov","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":205451,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

Various organochlorine pesticides, polychlorinated biphenyls, trace metals, and polycyclic aromatic hydrocarbons are a concern because of their ability to persist and accumulate in aquatic sediments and their association with adverse aquatic biological effects. The areal distribution and concentrations in surficial bed sediments of 20 contaminants of concern with established bed-sediment-toxicity guidelines were examined in relation to their potential effects on freshwater aquatic biota. Contaminants at more than 800 sampling locations are characterized in this report. Surficial bed-sediment-quality data collected from 1990 to 1997 in the Lake Erie– Lake Saint Clair Drainages were evaluated to reflect recent conditions. In descending order, concentrations of total polycyclic aromatic hydrocarbons, phenanthrene, total polychlorinated biphenyls, chrysene, benz[<i>a</i>]anthracene, benzo[<i>a</i>]pyrene, cadmium, lead, zinc, arsenic, and mercury were the contaminants that most commonly exceeded levels associated with probable adverse effects on aquatic benthic organisms. The highest concentrations of most of these contaminants in aquatic bed sediments are confined to the 12 specific geographic Areas of Concern identified in the 1987 Revisions to the Great Lakes Water Quality Agreement of 1972.

The objective of this particular study was to improve our understanding\nof the effects of different river discharges and lake levels of Coeur d'Alene Lake on the transport of cadmium, zinc, and lead within the main stem Coeur d'Alene River. In particular, water-quality data and loads during a broad range of hydrologic conditions were examined to determine if the river channel, flood plain, and associated ground water along the main stem Coeur d'Alene River acted as sources or sinks of trace elements. Water-quality samples were collected at six riverine stations and one lake station along a 35-mile reach during March, June, September, and October of 1999. Samples were analyzed for whole-water recoverable, filtered (0.45 micrometer), and dissolved (0.01 micrometer) concentrations of cadmium, zinc, and lead. Concentrations and loads of cadmium and zinc measured during the four sampling trips were predominately in the filtered and dissolved fraction ,rather than particulate. The smallest concentrations were measured during the June sampling trip when flows were high and snowmelt runoff diluted riverine concentrations. Conversely, the largest concentrations were measured during the latter two sampling trips when flows were low because a larger proportion of the river's discharge was contributed by ground-water inflow. During each sampling trip, cadmium and zinc concentrations generally decreased in a downstream directioeven as discharge increased in a downstream direction. Spatial and temporal trends exhibited by lead concentrations and loads during the four sampling trips were different from those of cadmium and zinc because of the propensity for lead to adsorb to sediment particles. Whole-water recoverable lead concentrations and loads during the four sampling trips were predominantly in the particulate fraction, with filtered and dissolved concentrations and loads composing a much smaller proportion of the recoverable fraction compared to cadmium and zinc. Filtered lead concentrations generally increased at a faster rate in the downstream direction than dissolved lead concentrations; thus, colloidallead either was being formed by complexation reactions or being added by sediment erosion in the downstream direction.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/ofr0134","collaboration":"Prepared in cooperation with U.S. Environmental Protection Agency","usgsCitation":"Woods, P.F., 2001, Concentrations and loads of cadmium, zinc, and lead in the main stem Coeur d'Alene River, Idaho&mdash;March, June, September, and October 1999: U.S. Geological Survey Open-File Report 2001-34, iv, 33 p., https://doi.org/10.3133/ofr0134.","productDescription":"iv, 33 p.","numberOfPages":"39","costCenters":[{"id":343,"text":"Idaho Water Science Center","active":true,"usgs":true}],"links":[{"id":262352,"rank":800,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/2001/0034/report.pdf"},{"id":262353,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/2001/0034/report-thumb.jpg"}],"country":"United States","state":"Idaho","city":"Coeur D'alene;Cataldo;Harrison","otherGeospatial":"Coeur D'alene Lake;Rose Lake;Post Falls Dam","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -117.0464,47.1971 ], [ -117.0464,47.9819 ], [ -115.995,47.9819 ], [ -115.995,47.1971 ], [ -117.0464,47.1971 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b16e4b07f02db6a5605","contributors":{"authors":[{"text":"Woods, P.

We\r\ncollected samples also from Hogum Creek, a tributary to the Blackfoot, from Copper\r\nCreek, a tributary to the Landers Fork, and from ground water seeps contributing to the\r\nflow along the Landers Fork. To better define the physical dynamics of the hydrologic\r\nsystem and to determine geochemical loads, we measured streamflow at all the sites where\r\nwe took samples for water quality analysis. The Upper Blackfoot River, which drains\r\nhistoric mines ca. 20 Km upstream of the study area, had higher trace metal concentrations\r\nthan did the Landers Fork, which drains the pristine Scapegoat Wilderness area. In both\r\nrivers, many of the major elements were inversely related to streamflow, and at some sites,\r\nseveral show a hysteresis effect in which the concentrations were lower on the rising limb\r\nof the hydrograph than on the falling limb. However, many of the trace elements followed\r\nfar more irregular trends, especially in the Blackfoot River. Elements such as As, Cu, Fe,\r\nMn, S, and Zn exhibited complex and variable temporal patterns, which included almost no\r\nresponse to streamflow differences, increased concentrations following a summer storm\r\nand at the start of snowmelt in the spring, and/or increased concentrations throughout the\r\ncourse of spring runoff. In summary, complex interactions between the timing and\r\nmagnitude of streamflow with physical and chemical processes within the watershed\r\nappeared to greatly influence the geochemistry at the sites, and streamflow values alone\r\nwere not good predictors of solute concentrations in the rivers.","language":"English","publisher":"U.S. Geological Survey","doi":"10.3133/ofr0159","usgsCitation":"Nagorski, S.A., Moore, J.N., and Smith, D., 2001, Geochemical baseline studies and relations between water quality and streamflow in the Upper Blackfoot watershed, Montana: Data for July 1997-December 1998: U.S. Geological Survey Open-File Report 2001-59, 99 p., https://doi.org/10.3133/ofr0159.","productDescription":"99 p.","costCenters":[],"links":[{"id":406783,"rank":2,"type":{"id":36,"text":"NGMDB Index Page"},"url":"https://ngmdb.usgs.gov/Prodesc/proddesc_37217.htm","linkFileType":{"id":5,"text":"html"}},{"id":2794,"rank":3,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/of/2001/ofr-01-0059/","linkFileType":{"id":5,"text":"html"}},{"id":161031,"rank":1,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"}],"country":"United States","state":"Montana","otherGeospatial":"Upper Blackfoot watershed","geographicExtents":"{\n  \"type\": \"FeatureCollection\",\n  \"features\": [\n    {\n      \"type\": \"Feature\",\n      \"properties\": {},\n      \"geometry\": {\n        \"type\": \"Polygon\",\n        \"coordinates\": [\n          [\n            [\n              -112.61,\n              46.949\n            ],\n            [\n              -112.498,\n              46.949\n            ],\n            [\n              -112.498,\n              47.017\n            ],\n            [\n              -112.61,\n              47.017\n            ],\n            [\n              -112.61,\n              46.949\n            ]\n          ]\n        ]\n      }\n    }\n  ]\n}","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b24e4b07f02db6ae61c","contributors":{"authors":[{"text":"Nagorski, Sonia A.","contributorId":32940,"corporation":false,"usgs":true,"family":"Nagorski","given":"Sonia","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":205368,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Moore, Johnnie N.","contributorId":102532,"corporation":false,"usgs":true,"family":"Moore","given":"Johnnie","email":"","middleInitial":"N.","affiliations":[],"preferred":false,"id":205369,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Smith, David B. 0000-0001-8396-9105 dsmith@usgs.gov","orcid":"https://orcid.org/0000-0001-8396-9105","contributorId":1274,"corporation":false,"usgs":true,"family":"Smith","given":"David B.","email":"dsmith@usgs.gov","affiliations":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true}],"preferred":false,"id":205367,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Paleoliquefaction studies have been used extensively in the central and eastern U.S. to assess seismic hazards, and could be used elsewhere to good purpose because paleoliquefaction studies in some field settings can reveal more than other methods, such as fault studies, about the prehistoric strength of shaking and earthquake magnitude. \r\n\r\nWe present guidelines for the conduct of a paleoliquefaction study in continental deposits, mainly in terms of the geologic/seismologic setting and geotechnical properties, because a successful interpretation requires factors from all these disciplines. No single discipline suffices alone. Their interactions must be appreciated in order to understand why seismically induced liquefaction features are found in some locales and not in others. \r\n\r\nThe guidelines that we present also relate to three primary issues for which liquefaction features are especially useful for interpretations: Where was the tectonic source? What was the strength of shaking? And what was the magnitude? In discussing these issues we focus on the following aspects of level-ground liquefaction: (1) mechanisms that form seismic liquefaction features in the field; (2) field settings where liquefaction features should be present if strong seismic shaking has occurred; (3) field settings where an absence of liquefaction features indicates an absence of strong seismic shaking; (4) how liquefaction features should be used to interpret the tectonic source locale of a paleo-earthquake; and (5) how effects of liquefaction can be used to back-calculate the strength of shaking as well as earthquake magnitude. \r\n\r\nSeveral methods are available to back-calculate the strength of shaking and earthquake magnitude, and the most commonly used methods are presented and critiqued. Our critique of these methods points out the uncertainties attending each. Paleoliquefaction/paleoseismic case histories are presented to illustrate potential uncertainties in back-calculations and procedures to overcome these uncertainties. \r\n\r\nReasonable confidence in paleoseismic interpretation generally requires using multiple methods of back-analysis, and achieving similar results from each method. An alternate approach can be used for paleo-earthquakes that were large enough to have caused liquefaction in a variety of geologic settings, in which there were differing factors affecting surface ground motions and liquefaction susceptibility. For this situation, a method such as the cyclic-stress method can be used to make back-calculations that can be cross-checked with results from other settings.","language":"ENGLISH","doi":"10.3133/ofr0129","usgsCitation":"Obermeier, S.F., Pond, E.C., Olson, S.M., Green, R.A., Stark, T., and Mitchell, J.K., 2001, Paleoliquefaction studies in continental setting; geologic and geotechnical factors in interpretations and back-analysis: U.S. Geological Survey Open-File Report 2001-29, 72 p., https://doi.org/10.3133/ofr0129.","productDescription":"72 p.","costCenters":[],"links":[{"id":160332,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":2743,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/openfile/of01-029/ ","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4ae4e4b07f02db689c53","contributors":{"authors":[{"text":"Obermeier, Stephen F.","contributorId":102482,"corporation":false,"usgs":true,"family":"Obermeier","given":"Stephen","email":"","middleInitial":"F.","affiliations":[],"preferred":false,"id":205331,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Pond, Eric C.","contributorId":82361,"corporation":false,"usgs":true,"family":"Pond","given":"Eric","email":"","middleInitial":"C.","affiliations":[],"preferred":false,"id":205328,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Olson, Scott M.","contributorId":11257,"corporation":false,"usgs":true,"family":"Olson","given":"Scott","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":205326,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Green, Russell A.","contributorId":94708,"corporation":false,"usgs":false,"family":"Green","given":"Russell","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":205329,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Stark, Timothy D.","contributorId":58317,"corporation":false,"usgs":true,"family":"Stark","given":"Timothy D.","affiliations":[],"preferred":false,"id":205327,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mitchell, James K.","contributorId":99598,"corporation":false,"usgs":true,"family":"Mitchell","given":"James","email":"","middleInitial":"K.","affiliations":[],"preferred":false,"id":205330,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

In the Nepaug area, surficial glacial materials overlie crystalline bedrock that is predominantly schist and gneiss. Along the western side of Nepaug Reservoir, glacial stratified deposits were laid down as ice-marginal deltas in a series of small glacial lakes that formed sequentially as the ice margin retreated northeastward through the area. These deposits are as much as 250 feet thick and are subdivided into coarse-grained units (gravel, sand and gravel, and sand deposits) and fine-grained units (very fine sand, silt, and clay deposits). Approximately 954 million cubic feet of sand and gravel is contained in four delineated deposits in two areas near the reservoir.</p>\n<br/>\n<p>The sand and gravel deposits adjacent to the Nepaug Reservoir can affect the physical and chemical responses of the watershed. Removal of the sand and gravel would likely result in increased streamflow peaks associated with storms and decreased streamflow during low-flow periods.

The purpose of this study was to determine the quality and quantity of water in the Verde River and in the shallow stream-channel deposits in the vicinity of the northern boundary of the reservation.</p>\n<br>\n<p>The quality of surface water entering the reservation at the northern boundary and of ground water in the shallow stream- channel deposits beneath the flood plain is suitable for most purposes. Concentrations of dissolved solids and major ions did not exceed water-quality standards. Dissolved oxygen and pH generally were in acceptable ranges for all designated uses. Total coliform counts and nutrient concentrations also did not exceed water-quality standards. Six organic compounds were detected; however, concentrations of these compounds were below U.S. Environmental Protection Agency Maximum Contaminant Levels. The presence of these organic compounds indicates that the water has been affected by anthropogenic activities. Concentrations of all trace metals were below the applicable State of Arizona Water Quality Standards for Surface Water and U.S. Environmental Protection Agency Maximum Contaminant Levels. Arsenic concentrations were below the Maximum Contaminant Level of 50 micrograms per liter at the time of collection and analysis; however, in January 2001, the U.S. Environmental Protection Agency set a new Maximum Contaminant Level of 10 micrograms per liter. All arsenic concentrations in surface water were 10 micrograms per liter or greater. Arsenic concentra-tion in ground water ranged from 6 to 9 micrograms per liter. The source of arsenic is probably oxidized arsenic compounds that are typically found in basin-fill sediments in southern Arizona.</p> \n<br>\n<p>Surface-water flow onto the reservation was determined from recorded discharge at the Verde River below Bartlett Dam and Verde River near Scottsdale streamflow-gaging stations from 1962?99. Average annual flow onto the reservation is about 13 cubic feet per second less than average annual discharge at the Verde River below Bartlett Dam and 17.5 cubic feet per second more than the average annual discharge at the Verde River near Scottsdale for years in which rainfall is less than 20 inches. Average daily flow onto the reservation also is about 13 cubic feet per second less than discharge at the Verde River below Bartlett Dam and 18.7 cubic feet per second more than discharge at the Verde River near Scottsdale for May through November. Flow onto the reservation for December through April is less predictable because of a large variation between dis-charges at the Verde River below Bartlett Dam and the Verde River near Scottsdale.</p>\n<br>\n<p>Correlation between the nine instantaneous discharge measurements made between January 1998 and August 1999 at the northern boundary and recorded discharge at the two streamflow-gaging stations is high; correlation coefficients were greater than 0.99. Instantaneous inflows onto the reservation can be related to discharges at the Verde River below Bartlett Dam and the Verde River near Scottsdale using the equations:</p> \n<br>\n<p>instantaneous inflow = 0.861(instantaneous discharge at the Verde River below Bartlett Dam) + 20 cubic feet per second, and,</p>\n<br> \n<p>instantaneous inflow = 0.893(instantaneous discharge at the Verde River near Scottsdale) + 36 cubic feet per second</p>\n<br> \n<p>for discharges that range from 102 to 704 cubic feet per second at the northern boundary.</p>\n<br>\n<p>The direction of ground-water flow is\napproximately parallel to the flow of the Verde\nRiver. Ground water has a minor component of\nflow into the river when the river stage is lower\nthan about 5 feet above the local datum. There is a\nminor component of flow into the stream-channel\ndeposits when the river stage is higher than about\n5 feet above the local datum. Ground-water inflow\nto the reservation in the Verde River streamchannel\ndeposits is about 1.1 cubic feet per second\nand is minor compared to the average annual\nstreamflow of 675 cubic feet per second at the\nVerde River below Bartlett Dam on the basis of\n111 years of record.</p>","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Tucson, AZ","doi":"10.3133/wri014151","collaboration":"Prepared in cooperation with the Fort McDowell Yavapai Nation","usgsCitation":"Hoffmann, J.P., and O’Day, C.M., 2001, Quality of water and estimates of water inflow, northern boundary area, Fort McDowell Indian Reservation, Maricopa County, Arizona: U.S. Geological Survey Water-Resources Investigations Report 2001-4151, vi, 40 p., https://doi.org/10.3133/wri014151.","productDescription":"vi, 40 p.","numberOfPages":"47","costCenters":[],"links":[{"id":288413,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":288412,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/wri/2001/4151/report.pdf"}],"scale":"100000","projection":"Lambert Conformal Conic projection","country":"United States","state":"Arizona","county":"Maricopa County","otherGeospatial":"Fort Mcdowell Indian Reservation","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -111.75,33.583333 ], [ -111.75,33.833333 ], [ -111.5,33.833333 ], [ -111.5,33.583333 ], [ -111.75,33.583333 ] ] ] } } ] }","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a6fe4b07f02db6409bc","contributors":{"authors":[{"text":"Hoffmann, John P. jphoffma@usgs.gov","contributorId":1337,"corporation":false,"usgs":true,"family":"Hoffmann","given":"John","email":"jphoffma@usgs.gov","middleInitial":"P.","affiliations":[],"preferred":true,"id":204402,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"O’Day, Christie M.","contributorId":34556,"corporation":false,"usgs":true,"family":"O’Day","given":"Christie","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":204403,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The program was designed by the U.S. Geological Survey and the Massachusetts Department of Environmental Protection, Division of Watershed Management, with input from many organizations involved in water-quality monitoring in the State, and focuses on inland surface waters (streams and lakes). The proposed monitoring program consists of several components, or tiers, which are defined in terms of specific monitoring objectives, and is intended to complement the Massachusetts Watershed Initiative (MWI) basin assessments. Several components were developed using the Neponset River Basin in eastern Massachusetts as a pilot area, or otherwise make use of data from and sampling approaches used in that basin as part of a MWI pilot assessment in 1994. To guide development of the monitoring program, reviews were conducted of general principles of network design, including monitoring objectives and approaches, and of ongoing monitoring activities of Massachusetts State agencies.Network tiers described in this report are primarily (1) a statewide, basin-based assessment of existing surface-water-quality conditions, and (2) a fixed-station network for determining contaminant loads carried by major rivers. Other components, including (3) targeted programs for hot-spot monitoring and other objectives, and (4) compliance monitoring, also are discussed. Monitoring programs for the development of Total Maximum Daily Loads for specific water bodies, which would constitute another tier of the network, are being developed separately and are not described in this report. The basin-based assessment of existing conditions is designed to provide information on the status of surface waters with respect to State water-quality standards and designated uses in accordance with the reporting requirements [Section 305(b)] of the Clean Water Act (CWA). Geographic Information System (GIS)-based procedures were developed to inventory streams and lakes in a basin for these purposes. Several monitoring approaches for this tier and their associated resource requirements were investigated. Analysis of the Neponset Basin for this purpose demonstrated that the large number of sites needed in order for all the small streams in a basin to be sampled (about half of stream miles in the basin were headwater or first-order streams) pose substantial resource-based problems for a comprehensive assessment of existing conditions. The many lakes pose similar problems. Thus, a design is presented in which probabilistic monitoring of small streams is combined with deterministic or targeted monitoring of large streams and lakes to meet CWA requirements and to provide data for other information needs of Massachusetts regulatory agencies and MWI teams.The fixed-station network is designed to permit the determination of contaminant loads carried by the State's major rivers to sensitive inland and coastal receiving waters and across State boundaries. Sampling at 19 proposed sites in 17 of the 27 major basins in Massachusetts would provide information on contaminant loads from 67 percent of the total land area of the State; unsampled areas are primarily coastal areas drained by many small streams that would be impossible to sample within realistic resource limitations. Strategies for hot-spot monitoring, a targeted monitoring program focused on identifying contaminant sources, are described with reference to an analysis of the bacteria sampling program of the 1994 Neponset Basin assessment. Finally, major discharge sites permitted under the National Pollutant Discharge Elimination System (NPDES) were evaluated as a basis for ambient water-quality monitoring. The discharge sites are well distributed geographically among basins, but are primarily on large rivers (two-thirds or more ","language":"ENGLISH","doi":"10.3133/wri014081","usgsCitation":"DeSimone, L.A., Steeves, P.A., and Zimmerman, M., 2001, Statewide water-quality network for Massachusetts: U.S. Geological Survey Water-Resources Investigations Report 2001-4081, 88 p., https://doi.org/10.3133/wri014081.","productDescription":"88 p.","costCenters":[],"links":[{"id":160301,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/usgs_thumb.jpg"},{"id":2883,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.water.usgs.gov/wri014081","linkFileType":{"id":5,"text":"html"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a07e4b07f02db5f9909","contributors":{"authors":[{"text":"DeSimone, Leslie A. 0000-0003-0774-9607 ldesimon@usgs.gov","orcid":"https://orcid.org/0000-0003-0774-9607","contributorId":195635,"corporation":false,"usgs":true,"family":"DeSimone","given":"Leslie","email":"ldesimon@usgs.gov","middleInitial":"A.","affiliations":[{"id":376,"text":"Massachusetts Water Science Center","active":true,"usgs":true},{"id":466,"text":"New England Water Science Center","active":true,"usgs":true}],"preferred":true,"id":204361,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Steeves, Peter A. 0000-0001-7558-9719 psteeves@usgs.gov","orcid":"https://orcid.org/0000-0001-7558-9719","contributorId":1873,"corporation":false,"usgs":true,"family":"Steeves","given":"Peter","email":"psteeves@usgs.gov","middleInitial":"A.","affiliations":[{"id":41514,"text":"Maryland-Delaware-District of Columbia  Water Science Center","active":true,"usgs":true}],"preferred":true,"id":204360,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Zimmerman, Marc James","contributorId":104888,"corporation":false,"usgs":true,"family":"Zimmerman","given":"Marc James","affiliations":[],"preferred":false,"id":204362,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
