Contamination Of Boone-St. Joe Limestone Groundwater By Septic Tanks And Chicken Houses, Gerald D. Cox, Albert E. Ogden, Gretta Slavik

Journal of the Arkansas Academy of Science

Eighty-one water samples were collected from wells in the Boone-St. Joe limestone aquifer of northwest Arkansas and analyzed for fecal coliform, fecal streptococcus, total coliform bacteria, chloride, phosphate, nitrate and sulfate to determine the degree of contamination. Forty-nine percent of the samples had fecal streptococcus counts greater than 1 colony per 100 ml, 68% had total coliform counts of 1 or more colonies per 100 ml, and 9% of the wells had fecal coliform counts of 1 or more colonies per 100 ml. Water from wells in Clarksville, Nixa, Noark, Tonti and Waben cherty silt loam soils showed from 83 …

Mercury Content Of Waters In The Midcontinent Region, Larry Barber Ii, Kenneth F. Steele

Journal of the Arkansas Academy of Science

Two major areas of the midcontinent region were investigated for their aqueous mercury concentrations. Sixteen surface water and 17 ground water samples were collected in an eleven county area of N.W. Arkansas, S.W. Missouri and N.E. Oklahoma (Ozark area) and analyzed for total dissolved mercury by the flameless atomic absorption spectrophotometric method. The range (<0.2 to 0.8 ppb), the mean (0.4 ppb) and the median (0.4 ppb) are the same for both ground water and surface water. Values obtained for the Ozark area are slightly greater than those reported for surface water by others (about 0.1 ppb), but are well within the range reported for surface waters (0.1 to 17.0 ppb). The range for 102 ground water samples from the Ouachita Mountain area is <0.1 to 2.3 ppb, the mean 0.3 ppb and the median 0.1 ppb. Thus, the mercury values for this area are similar to those of the Ozark area except fora higher upper range. The mercury mineralization (cinnabar) in the southern part of the Ouachita Mountain area, in part, is the cause of the higher values. Only two samples (2.1 and 2.3 ppb), both from the Ouachita Mountain area, exceed the EPA drinking water limits of 2 ppb mercury in the western Arkansas region.

Preliminary Investigation Of The Ground-Water Resources Of Northern Searcy County, Arkansas, Wyndal M. Goodman, Albert E. Ogden

Journal of the Arkansas Academy of Science

Two aquifers are extensively used by residents of small communities and rural areas in northern Searcy County, Arkansas. The Mississippian Boone-St. Joe aquifer is generally the less productive and the shallower of the two. Ground-water yields for the Boone-St. Joe range from 0.5 to 75 gpm with a median yield of 5 and a mean of 9.8 gpm. Well depths range from 100 to 754 feet with a median depth of 350 feet and a mean of 360 feet. Confined conditions are indicated by the greater depths, whereas the Boone-St. Joe aquifer is unconfined when exposed at the surface. Underlying …

Preliminary Investigation Of The Ground-Water Resources Of Baxter, Fulton, Izard And Sharp Counties, Arkansas, Mike Liebelt, Gerald Lundy, Albert E. Ogden

Journal of the Arkansas Academy of Science

One hundred and seventy-seven drillers' well reports were used to investigate the groundwater resources of Baxter, Fulton, Izard, and Sharp counties. The most widely utilized aquifer zone is composed of the Cotter and Jefferson City dolomites. The well depths range from 30 to 740 ft. with a mean and median of 264 and 225 ft., respectively. The drillers' yield estimates range from 1 to 50 gpm with a mean of 12.0 gpm and a median of 10 gpm. The piezometric surface has an average hydraulic gradient of 9 ft./mile with groundwater discharge occurring along the Spring and White Rivers. Overlying …

Hydrogeologic And Geochemical Investigation Of The Boone-St. Joe Limestone Aquifer In Benton County, Arkansas, Albert E. Ogden

Arkansas Water Resources Center Technical Reports

The Boone-St. Joe limestone aquifer is an important unconfined aquifer for rural residents of Benton County, Arkansas. Pumping tests indicate a large range in production capability of the aquifer. The coefficient of transmissibility and specific capacity range from 24.8 to 24640 gpd/ft and 0.03 to 30 gpm/ft, respectively. No statistical relationship at a = 0.10 was found between each of these parameters and photo-lineament proximity. Drillers' estimated well yield (gpm) also showed no relationship to photo-lineament proximity. It is therefore concluded that choosing well sites along photo-lineaments for higher production is not as reliable for karstified carbonate aquifers such as …

Changing Fields: Agricultural Land Use Changes In Nebraska 1925-1974, Donald A. Wilhite

National Drought Mitigation Center: Faculty Publications

The series of graphs and maps which follow illustrate agricultural land use changes in Nebraska from 1925 to 1974. With these graphs and maps, the major agronomic crops of corn (dryland and irrigated), wheat, sorghum and soybeans are analyzed. The purpose of this analysis is to provide a pictorial history of Nebraska's ever-changing cropping system and, hopefully, to stimulate ideas and discussion with regard to trends and future directions. The Nebraska Water Resources Center is deeply interested in both the past and the future of Nebraska's agriculture because of the demands which agriculture places on the state's water resources.

Turbulence Spectra Above A Vegetated Surface Under Conditions Of Sensible Heat Advection, Raymond P. Motha, Shashi B. Verma, Norman J. Rosenberg

National Drought Mitigation Center: Faculty Publications

Spectra of vertical and horizontal velocity, air temperature and humidity fluctuations were analyzed from measurements made over a well-watered alfalfa crop under conditions of sensible heat advection. Vertical velocity and air temperature spectra as well as cospectra of momentum, sensible heat and water vapor were found to be dependent on atmospheric thermal stratification. These spectra and cospectra were shifted toward higher frequencies under advective as compared to lapse conditions. These results indicate that the predominant eddy sizes are relatively smaller under advective conditions. Humidity spectra, on the other hand, were independent of daytime thermal stratification conditions but were influenced by …

Preliminary Investigation Of Rural-Use Aquifers Of Boone, Carroll, And Madison Counties, Arkansas, Albert E. Ogden, Nancy L. Taylor, Steve D. Thompson

Journal of the Arkansas Academy of Science

Approximately 500 water wells having driller's lithologic logs were plottedin Boone, Carroll, and Madison Counties, Arkansas. Three aquifers were found to be used by the rural residents and smaller communities. The most shallow of these is the Mississippian Boone-St. Joe aquifer. This aquifer is generally the least productive having a range of .25 to 60 gpm but a median productivity of only 5 gpm. Well depths for the Boone-St. Joe range from 46 to 464 ft. and have a median depth of 225 ft. The Boone-St. Joe aquifer is unconfined to semi-confined and yields sufficient quantities of water only when …

Hydrogeologic Investigation Of A Landfill Site In Washington County, Arkansas, Albert E. Ogden, Carlos J. Quintana

Journal of the Arkansas Academy of Science

A proposed landfill site near Wheeler, Washington Co., Arkansas, was investigated for its hydrogeologic suitability. The site is located on the highly fractured, cavernous, and cherty Boone Ls. The site is a small upland valley 4500 ft. north of Clear Creek. The valley containing the proposed site is a karst dry valley in which precipitation rapidly infiltrates, recharging the water table and local springs. The water table around the site was mapped to determine the hydraulic gradient and direction of ground-water movement. The water table slopes in a SE direction from the landfill towards Clear Creek with a steep hydraulic …
