Predicting Infiltration And Surface Runoff From Reconstructed Spoils And Soils, Larry G. Wells, Andrew D. Ward, Ronald E. Phillips

KWRRI Research Reports

A laboratory system was fabricated to measure infiltration and runoff from spoil and soil profiles constructed in rectangular bins. Construction, calibration and operation of a rainfall simulator is discussed and instrumentation used to measure transient infiltration and transmittance of water through experimental profiles is described.

Spoil and soil materials from surface mines in Eastern and Western Kentucky were transported to the laboratory and used in constructing experimental profiles in rectangular bins (0.91 x 1.83 x 1.07 m). An extensive series of infiltration experiments were conducted utilizing a rainfall simulator and soil moisture monitoring instrumentation. A dual probe gamma density gauge …

Studies In Dye-Tracing Technologies In Karst Hydrogeology, John Thrailkill, Phillip E. Byrd, Stephen B. Sullivan, Lawrence E. Spangler, Charles J. Taylor, Greta K. Nelson, Kevin R. Pogue

KWRRI Research Reports

Information on fluorescent dyes used for water tracing and the results of six studies are reported. Optical brightener, direct yellow, fluorescein, rhodamine (WT), and other dyes are described and the procedures employed in their use ·in the field and in equilibration experiments are discussed. Three of the six studies consisted of investigations of the equilibration with passive detectors of three of the dyes. The absorption of optical brightener on fabric detectors was apparently linear with concentration and with immersion time, while detectors became rapidly saturated with direct yellow. Equilibrium of fluorescein on charcoal detectors with an elutriating solution was not …

Movement Of Bacteria Through Macropores To Ground Water, M. Scott Smith, Grant W. Thomas, Robert E. White

KWRRI Research Reports

Effects of soil type, flow rate, antecedent soil moisture and other factors on transport of E. coli through soils was measured on disturbed and intact columns 20 cm in diameter by 25 to 30 cm in depth. Added E. coli were distinguished from indigenous microbes using an antibiotic resistance marker. Transport of Cl^- and ³H₂O was also measured. Up to 96 percent of the bacteria irrigated onto the surface of intact columns were recovered in the effluent. Soil structure appeared to be related to the extent of transport. Columns prepared from mixed, repacked soil were much …

Baseline Study For Monitoring Variations In Nitrate Concentration In Surface Waters Of Cuyamaca Rancho State Park In Relation To Watershed Types, Lester E. Harris Iii

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to compare the variations in nitrate concentration in the surface waters of five different watershed community types at Cuyamaca Rancho State Park. Monthly water samples were collected at selected sites below each watershed and analyzed by use of a specific ion electrode for nitrate concentration. Results indicate that variations in nitrate concentration are influenced by seasonal variation in rainfall. The yellow pine forest/chaparral watershed showed the highest mean nitrate concentration, three to four times higher than the other watershed types analyzed. Peak nitrate concentrations did not approach the maximum safe limit for human or …

A Systematic Study To Reduce Trihalomethane Precursors In Little Rock Drinking Water By Combined Alum Coagulation-Powdered Activated Carbon Treatment, Ali U. Shaikh

Technical Reports

Studies have been conducted to evaluate powdered activated carbon (PAC) as an agent for controlling trihalomethanes in drinking water. Laboratory studies indicate that PAC is highly efficient in removing free trihalomethanes in water within a few hours. The removal efficiency of humic acid, a known THM precursor, by PAC is considerably less. However, longer treatment time can remove the precursors quite significantly. Humic substances in surface water samples can also be removed by PAC.

Effects Of Sewage Pollution In The White River, Arkansas On Benthos And Leaf Detritus Decomposition, Arthur V. Brown, Lawrence D. Willis, Peter P. Brussock

Technical Reports

Recently there has been much emphasis placed on the importance of leaf detritus processing to the energetics of stream invertebrates. This study was designed primarily to assess the effects of municipal effluent on the ability of a stream community to utilize leaf detritus, and secondarily to evaluate the extent of the pollution of the White River by the Fayetteville, Arkansas effluent discharge. Physical and chemical water quality, benthos, and fish were sampled periodically at one station upstream and two stations downstream from the discharge, and in the Richland Creek tributary. Processing of leaf detritus was studied at each site using …

Chemistry Of The Springs Of The Ozark Mountains, Northwestern Arkansas, Kenneth F. Steele

Technical Reports

Three lead-zinc mineralized areas of northern Arkansas were selected to study the effect of mineralization on ground water chemistry. The Ponca area has the largest amount of lead sulfide mineralization, the Zinc area has a significant amount of zinc silicate and zinc sulfide; whereas, the Rush area has zinc carbonate and zinc sulfide. A total of 143 samples were collected from these areas and analyzed for general water chemistry parameters including heavy metal The water quality of the area is generally good; however, a few springs exceed the drinking water standards for ammonia, nitrate, iron, manganese and lead. The surface …

Causes Of Localized Copper Corrosion In Drinking Water Supplies, R. A. Sims, R. W. Raible

Technical Reports

Excessive amounts of copper have been observed in drinking water at certain installations on Lake DeGray and at isolated locations in the Arkadelphia area of Arkansas. A study of these installations was conducted to determine the source of the copper contamination. The supply water was very low in copper and therefore dissolution of the copper plumbing caused by low water pH and long residence times was determined to be the most probable source.

Disposal Of Household Wastewater In Soils Of High Stone Content (1977-1980), E. M. Rutledge, C. R. Mote, M. S. Hirsh, H. D. Scott, D. T. Mitchell

Technical Reports

Two experimental septic tank filter fields were constructed with built-in monitoring equipment in Nixa soils. These soils contain many chert fragments and a fragipan about 60 cm deep which restricts downward water movement and is the design-limiting feature. The standard filter field (76 cm deep) was built into the fragipan and the modified standard filter field (30 cm deep) was placed above it. During 30 months' observation, the modified standard performed better than the standard filter field. Maximum rise of effluent in the standard and modified standard came within 11 and 19 cm of the soil surface, respectively. Performance of …
