The authors ' best estimates ' of vertical permeabilities of two confining units are 1 x 10 super -2 foot per day and 2 x 10 super -4 foot per day. Theoretical travel-time calculations indicate that minor amounts of pollutants may reach the upper confined aquifer after many tens of years, but that water of the composition of the leachate probably would not reach the aquifer for more than three centuries. The range of error in the theoretical travel-time calculations is likely to be plus or minus a factor of two or three.

Water-quality characteristics determined include specific conductance, pH, water temperature, major dissolved cations, major dissolved anions, and coliform bacteria. Concentrations of hardness, nitrite plus nitrate, coliform bacteria, dissolved solids, sulfate, chloride, fluoride , iron, calcium, magnesium, sodium, potassium or bicarbonate exceed public drinking water regulation limits or were anomalously high in some water samples. Highly mineralized ground water probably is due to the natural composition of the aquifers and not to surface contamination. Concentrations of coliform bacteria that exceed public drinking water limits and anomalously high dissolved nitrite-plus-nitrite concentrations are from 15- to 20-year old irrigation wells in heavily irrigated or more densely populated areas of the valleys. Ground-water quality and quantity in most of the study area are sufficient to meet current (1978) population and economic demands. Ground water in all valleys is characterized by significant concentrations of calcium, magnesium, and bicarbonate plus carbonate ions.

In 1975, the population of the area was about 48,000. Water use averaged 11.4 million gallons per day; about half was pumped from wells and half from streams.</p><p>The area receives 57 inches of precipitation per year on the average. Much of this water enters the surficial sand aquifer, seeps to streams, or enters the underlying water-bearing zone of the upper confining unit and the Floridan aquifer.</p><p>The water-bearing zone of the upper confining unit is used for rural domestic supplies and is also important because the water it stores is a source of recharge to the underlying Floridan aquifer.</p><p>The Floridan aquifer underlies all of the Ochlockonee River area and, except for the city of Quincy, is the principal source of municipal water supply. Well yields range from as little as 20 gallons per minute in Gadsden County to as much as 4,500 gallons per minute in Leon County. The transmissivity of the Floridan aquifer ranges from about 170 feet squared per day in the southern part of the area to 5,100 feet squared per day in the northern part. Storage coefficients calculated from two aquifer tests are 2 x 10-4 and 2.6 x 10-4. At Tallahassee, directly east of the Ochlockonee River, transmissivity is as high as 130,000 feet squared per day. The Floridan aquifer is recharged by downward leakage of water from the surficial sand aquifer and from the water-bearing zone of the upper confining unit. The Floridan aquifer is also recharged directly by rainfall in northern Leon County and in southern Georgia where it is near or at land surface. Ground water moves toward the southeast from the potentiometric high in southwestern Gadsden County and south from Leon County toward Wakulla Springs, located about 10 miles south of Tallahassee. The potentiometric surface of the upper part of the Floridan aquifer ranges from about 50 feet higher than that of the middle and lower part of the Floridan aquifer in southwestern Gadsden County to about 10 feet higher near Midway in eastern Gadsden County. The aquifer discharge in the basin area is by wells and by natural discharge through seeps and springs along the Ochlockonee River and at Ochlockonee Bay.</p><p>Water levels in the Floridan aquifer fluctuate in response to seasonal and long-term variations in rainfall. Hydrographs do not show evidence of any long-term water-level declining trend.</p><p>Saline water (more than 1,000 milligrams per liter of dissolved solids) occurs naturally within the Floridan aquifer throughout the Ochlockonee River area at depths ranging from 200 to 600 feet below sea level. The depth below which dissolved solids in water exceed 500 milligrams per liter in the Havana area ranges from 200 to 250 feet below sea level; in the Quincy area, from 400 to 450 feet below; and in the Greensboro area, from 200 to 250 feet below.</p><p>Concentrations of dissolved solids in water pumped from wells tapping the Floridan aquifer in the Ochlockonee River area range from 60 to 1,370 milligrams per liter; chloride from 0 to 630 milligrams per liter; sulfate from 0.0 to 280 milligrams per liter; and fluoride from 0.0 to 1.3 milligrams per liter.</p><p>Streamflow originating in the Ochlockonee River area in Florida averages about 1,000 million gallons per day; minimum discharge during dry periods is about 285 million gallons per day. Stream yields range from 0.90 to 2.62 cubic feet per second per square mile. Quincy Creek, at State Highway 267 at Quincy, the primary source of water for the city of Quincy, yields an average flow of 19 million gallons per day, has a 7-day 10-year low flow of 2.8 million gallons per day, and contains water of acceptable quality. The chemical quality of most streams in the basin is acceptable for most uses. Dissolved-solids concentration is generally less than 135 milligrams per liter; pH ranges from 5.3 to 7.3 units; color from 20 to 90 platinum-cobalt units; and turbidity from 3 to 85 Jackson turbidity units.

Hardgrounds and two faults described in previous literature also are shown on the map. \r\n\r\nOn the Continental Shelf, at least two faults, the Helena Banks fault and the White Oak lineament, appear to be tectonic in origin. However, a lack of historical seismicity associated with these faults indicates that they are probably not active at the present time. Hardgrounds are widely scattered but are most abundant in Onslow Bay. Although paleostream channels are common nearshore, they do not appear to be common on the central and outer shelf except off Albemarle Sound where extensive Pleistocene, Pliocene, and late Miocene channels extend across the shelf. Mobile bottom sediments are confined mainly to the shoals off Cape Romain, Cape Fear, Cape Lookout, and Cape Hatteras. Elsewhere the sand cover is thin, and older more indurated rocks are present in subcrop. \r\n\r\nNo slope-instability features were noted on the Florida-Hatteras slope off North Carolina. The lack of features indicates that this slope is relatively stable. \r\n\r\nEvidence for scour by strong currents is ubiquitous on the northern Blake Plateau although deep-water reefs are sparse. The outer edge of the plateau is dominated by a major growth fault and numerous splay and antithetic faults. These faults are the product of salt tectonism in the Carolina trough and thus are not associated with seismicity. Displacements observed near the sea floor and breached diapirs offshore indicate that the main fault is still moving. Associated with the faults are collapse features that are interpreted to be caused by karst solution and cavernous porosity in Eocene and Oligocene limestones at depth. \r\n\r\nMajor slumps have taken place in two large areas of the Continental Slope. Seismic-reflection profiles of the southern area, centered on the lower slope at 1at. 33?N., long. 76?W., show a 80-m-hlgh scarp in which bedding has been truncated. Rotational slump faults are present in this area on the middle and upper slope. Sidescan images show that large blocks have slid downslope from the scarp face, furrowing the bottom. High-resolution (3.5-kHz) records show that the rotational slump faults upslope are active. The association of these slumps and the scarps with salt diapirs suggests subsidence accompanying salt tectonism as the cause. Seismic-reflection records over the northern area, at about fat. 36?20'N., long. 74?40'W., show two steep scarps, each about 225 m high on the upper and middle-slope. These slump scars and an absence of Pleistocene sediments indicate that large blocks of the slope have been removed by slumping. \r\n\r\nThe slope north of fat. 35?N. is highly dissected by canyons. Mid-range sidescan-sonar records suggest that the canyons are the product of mass wasting and have probably formed largely by slumping. \r\n\r\nSediments in a wide zone on the upper rise are highly disturbed and faulted owing to salt tectonism. Twenty-six salt diapirs are mapped, as is a zone of disturbed bottom related to salt tectonism. \r\n\r\nAn area of frozen bottom (clathrate) under which shallow free gas is trapped underlies the outer Blake Plateau, the slope, and the upper rise. Although the hazards of drilling into or through clathrates have not been tested, the release of gas from beneath this frozen layer may prove to be a primary hazard to exploration.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82136","usgsCitation":"Popenoe, P., Coward, E., and Cashman, K.V., 1982, A regional assessment of potential environmental hazards to and limitations on petroleum development of the Southeastern United States Atlantic continental shelf, slope, and rise, offshore North Carolina: U.S. Geological Survey Open-File Report 82-136, 71 p., 1 over-size sheet, maps ;28 cm., https://doi.org/10.3133/ofr82136.","productDescription":"71 p., 1 over-size sheet, maps ;28 cm.","costCenters":[],"links":[{"id":143343,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0136/report-thumb.jpg"},{"id":38538,"rank":400,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0136/plate-1.pdf","linkFileType":{"id":1,"text":"pdf"}},{"id":38539,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0136/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4b1ae4b07f02db6a849d","contributors":{"authors":[{"text":"Popenoe, Peter","contributorId":62206,"corporation":false,"usgs":true,"family":"Popenoe","given":"Peter","email":"","affiliations":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":false,"id":161864,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Coward, E.

Four tracts assessed were located in the outcrop of three coal groups and of other relatively impermeable rocks in the Pottsville Formation. Physical settings of the tracts and most other areas in the Warrior coal field are similar. This results in similar ground-water and surface-water characteristics, in similar impacts resulting from surface coal mining, and in maximizing the transfer-ability of data. Assessments of the tracts reflected the small storage of water in underlying rocks and corresponding low yields to wells and to the base flow of streams. Ground water and surface water in undisturbed areas are generally of good quality. Some subbasins in the tracts have already been impacted by mining. Estimates of streamflow characteristics and the availability and quality of ground water in the tracts were made using available methodology , or assessments based on local and regional data. Estimates of the degree mineralization of surface-water were made using methodology developed from other coal hydrology work. Climatic, physiographic, hydrologic, and land-use data were analyzed by regressions to derive relations for assessing water quality in streams draining mined and unmined areas. In this approach, an equation was derived to estimate specific conductance. Additional equations, based on relations between specific conductance and other constituents, allow estimates of mine drainage indicators such as hardness, dissolved solids, and sulfate. Hydrologic assessments of the tracts, based on limited verification data, proved to be reasonably accurate.

Bear and Blue Creek basins are underlain predominantly by relatively impermeable consolidated rocks in the Pottsville Formation. Turkey and Yellow Creek basins are underlain predominantly by permeable unconsolidated rocks in the Coker Formation. \r\n\r\nWell yields from the Pottsville Formation generally range from 0 to 5 gallons per minute and those from the Coker Formation generally range from 5 to 100 gallons per minute. With the exception of locally objectional concentrations of dissolved iron and manganese, ground water in the basins is suitable for most uses. \r\n\r\nStreamflow distribution reflects seasonal precipitation. Storm runoff is characterized by concentrated peakflows of short duration that rapidly recede to low flow. Streams draining basins underlain mainly by the Pottsville Formation frequently go dry, whereas those draining basins underlain chiefly by the Coker Formation have well-sustained low flows.\r\n\r\nSurface water is generally acidic and low in dissolved solids. Water in streams draining basins underlain chiefly by the Pottsville Formation is slightly more mineralized and less acidic than water in streams draining areas underlain chiefly by the Coker Formation. Climatic, physiographic, hydrologic, and land-use data are analyzed by regressions to derive relations for estimating water quality in streams draining mined and unmined areas. \r\n\r\nThe impacts of mining on the hydrologic systems are identified as increased erosion and sedimentation, baseflow augmentation, decline in groundwater levels, and degradation of water quality. \r\n\r\nA digital model was calibrated to simulate streamflow for Bear, Blue, and Yellow Creeks under unmined conditions. The model, when calibrated and verified under mined and unmined conditions, can be coupled with developed water-quality relationships. This will permit a general examination of .surface-water characteristics (quantity and quality), and estimation of hydrologic impacts that will result from surface mining.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82105","usgsCitation":"Puente, C., and Newton, J., 1982, Hydrology of potential mining areas in the Warrior coal field, Alabama: U.S. Geological Survey Open-File Report 82-105, 117 p., 10 over-size sheets, ill., maps ;28 cm., https://doi.org/10.3133/ofr82105.","productDescription":"117 p., 10 over-size sheets, ill., maps ;28 cm.","costCenters":[],"links":[{"id":112942,"rank":410,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_02.pdf","size":"2786","linkFileType":{"id":1,"text":"pdf"}},{"id":112943,"rank":411,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_03.pdf","size":"3319","linkFileType":{"id":1,"text":"pdf"}},{"id":112944,"rank":412,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_07.pdf","size":"507","linkFileType":{"id":1,"text":"pdf"}},{"id":112945,"rank":413,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_16.pdf","size":"645","linkFileType":{"id":1,"text":"pdf"}},{"id":112946,"rank":414,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_17.pdf","size":"485","linkFileType":{"id":1,"text":"pdf"}},{"id":112947,"rank":415,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_18.pdf","size":"263","linkFileType":{"id":1,"text":"pdf"}},{"id":112948,"rank":416,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_20.pdf","size":"2434","linkFileType":{"id":1,"text":"pdf"}},{"id":112949,"rank":417,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_21.pdf","size":"3675","linkFileType":{"id":1,"text":"pdf"}},{"id":112950,"rank":418,"type":{"id":17,"text":"Plate"},"url":"https://pubs.usgs.gov/of/1982/0105/plate-figure_22.pdf","size":"2647","linkFileType":{"id":1,"text":"pdf"}},{"id":143601,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0105/report-thumb.jpg"},{"id":38562,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0105/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e4a0ee4b07f02db5fdaff","contributors":{"authors":[{"text":"Puente, Celso","contributorId":36140,"corporation":false,"usgs":true,"family":"Puente","given":"Celso","email":"","affiliations":[],"preferred":false,"id":161909,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Newton, J.G.","contributorId":71552,"corporation":false,"usgs":true,"family":"Newton","given":"J.G.","email":"","affiliations":[],"preferred":false,"id":161910,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The hydrogeologic units in the area include the Floridan aquifer, which is made up of parts of the Lake City Limestone, the Avon Park Limestone, and the Ocala Limestone, all of Eocene age; the confining bed, which is composed of clays of Miocene or Pliocene age; and the surficial aquifer, which is made up of Pleistocene and Holocene sands. \r\n\r\nOrnamental fern growing is a $12 million per year industry in northwest Volusia County. Fern culture requires a large amount of good-quality water for irrigation, and more significantly, a large water withdrawal rate for freeze protection during winter months. The source of most water used is the Floridan aquifer. The large irrigation withdrawals, especially in winter months when spray irrigation is used for freeze protection of ferns, introduce problems such as the potential for saltwater intrusion, the temporary loss of water in domestic wells caused by large potentiometric drawdown, and increased sinkhole activity. \r\n\r\nThe water budget of the surficial layer consists of 55 inches per year rainfall, 39 inches per year evapotranspiration, 13 inches per year runoff, and a net downward leakage of 3 inches per year. \r\n\r\nAverage ground-water irrigational withdrawal is 8.1 million gallons per day, while the peak withdrawal rate is 300 million gallons per day during freeze-protection pumpage. The average irrigation well depth exceeds 300 feet. \r\n\r\nTransmissivities of the Floridan aquifer range from 4,500 to 160,000 feet squared per day. Highest transmissivities are in the DeLeon Springs area and the lowest are in the east Pierson area. Storage coefficients range from 0.0003 to 0.0013.\r\n\r\nThe water budget of the Floridan aquifer under present conditions of withdrawal consists of 108 cubic feet per second recharge, 2 cubic feet per second horizontal ground-water inflow, 34 cubic feet per second direct discharge, 40 cubic feet per second upward leakage, 22 cubic feet per second horizontal outflow, and 14 cubic feet per second pumpage. \r\n\r\nThe Floridan aquifer contains good-quality water in most of the study area, but also contains brackish water underneath the stressed zones and in the upper zones along the western and southern limits of the area. The altitude of the fresh- saltwater interface varies in the area from 1,500 to 300 feet below sea level. \r\n\r\nAreal drawdowns in the fern-growing areas of Pierson are 5 feet during growth irrigation periods and 20 to 30 feet during freeze-protection withdrawals. The drawdown in the Pierson area at the end of one intense period of pumpage exceeded 30 feet over a 4.4-square-mile area. A significant amount of the withdrawn water was replaced by leakage during the pumping period. Drawdowns in some pumping wells in northeast Pierson exceed 90 feet during freeze-protection withdrawals. \r\n\r\nNo long-term residual drawdown has occurred. The predominant effect of pumpage on the water budget of the Floridan aquifer has been an increase in recharge. Sinkhole activity has been increased by the temporary increase in load on the aquifer's skeletal structure during intense lowering of the potentiometric surface. There is no evidence of saltwater intrusion, but a monitoring network for future early detection is suggested.","language":"ENGLISH","publisher":"U.S. Geological Survey,","doi":"10.3133/ofr82108","usgsCitation":"Rutledge, A.T., 1982, Hydrology of the Floridan Aquifer in Northwest Volusia County, Florida: U.S. Geological Survey Open-File Report 82-108, 116 p, https://doi.org/10.3133/ofr82108.","productDescription":"116 p","costCenters":[],"links":[{"id":144339,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/of/1982/0108/report-thumb.jpg"},{"id":38703,"rank":300,"type":{"id":11,"text":"Document"},"url":"https://pubs.usgs.gov/of/1982/0108/report.pdf","linkFileType":{"id":1,"text":"pdf"}}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"4f4e49e2e4b07f02db5e499f","contributors":{"authors":[{"text":"Rutledge, A.

The Cretaceous units contain saltwater throughout the basin. The Tertiary units contain freshwater to varying distances downdip from outcrop areas in the basin. Natural flow directions and rates of movement of groundwater have been changed in the salt-dome basin by the withdrawl of freshwater and by the injection of wastes (principally oil-field brines) into saline aquifers.
