    Effect of Wastewater on the Concentrations of Mo, Zn, Cu, and Ni in Mill Creek at Marysville, Ohio
    (1998-09) Mensing, Teresa M.; Faure, Gunter
    The presence of Zn, Cu, and Ni in solution in streams may be used to find deposits of the ore minerals of these metals in the Silurian carbonate rocks in northwestern and west-central Ohio. However, the concentrations of these metals in streams may be increased by discharge of municipal and industrial wastewater. In the present study, a suite of water samples from Mill Creek in Union County, OH, was analyzed in order to determine to what extent wastewater discharged by the City of Marysville alters the chemical composition of the water. The data indicate that the concentrations of Na, K, and P increase significantly whereas those of Mg, Ca, Sr, and Ba decrease slightly. In addition, the concentrations of Mo, Zn, Cu, and Ni also rise, thereby changing the chemical signature of the water. The results demonstrate that the municipal wastewater of the City of Marysville is a significant source of transition metals in Mill Creek.

    Laboratory Scale Septic Tanks
    (1998-09) Peeples, James; Mancl, Karen M.
    Laboratory studies of on-site wastewater treatment systems require a dependable supply of septic tank effluent. The goal of this study was to produce a daily supply of septic tank effluent of approximately 140 mg/1 BOD5, 75 mg/1 TSS, and 30 mg/1 NH3-N for use in laboratory studies. The laboratory tank had to be easy to operate, and emulate a septic tank by producing some fluctuation in effluent quality, have the ability to maintain sludge and scum layers, and operate with minimal maintenance. Nine replicates of laboratory septic tanks were developed and tested for twelve weeks. Tanks were constructed from 114 1 cylindrical polyethylene containers with lids, a floating baffle, and discharge pipe. The tanks received a daily mixture of primary sludge, ammonium chloride, and tap water. The resulting septic tank effluent averaged l 6 l mg/1 BOD5, 75 mg/1 TSS, and 25 mg/1 NH3-N.

    Development and Implementation of a Graphical User Interface to Examine Land-Use Planning Efforts in Licking County, Ohio
    (1998-09) Peters, Tim; Nichols, Joan
    A Graphical User Interface (GUI) was developed in ARC/INFO to provide land-use planners and land owners with a user-friendly tool to access and query a digital database on various planning issues or concerns in Licking County. Planners from Licking County and the Resource Analysis Section (RAS) at the Ohio Department of Natural Resources (ODNR) were surveyed to identify the essential data layers needed to address each agency's specific planning initiatives. Two case studies were developed to implement the GUI. The first case study is theory based and involves an examination of potential sites for conservation tillage practices on potentially highly erodible land. The second case study is a real-world application, derived from an interest expressed by planners from both agencies to identify potential large-scale development sites within the county. The overall performance of the GUI was evaluated by land-use planners that found the interface more user-friendly and efficient than manual techniques.

    The Ground Beetles (Coleoptera: Carabidae) of Stillfork Swamp Nature Preserve, Carroll County, Ohio
    (1998-09) Usis, John D.; MacLean, David B.
    One hundred and one species of Carabidae, including Bembidion incrematum LeConte, Pterostichus caribou Ball, Amara lunicollis Schi0dte, Stenolophus rotundatus LeConte, and Lebia tnoesta LeConte, new state records, representing 32 genera were identified from light trap collections operated during 1984 and 1986-1988 in the open wetland, and from barrier pitfall traps placed in an adjacent swamp oak—hawthorn forest in 1992. Most species are hygrophilous. Species richness was highest in Agonum and Bembidion. Pterostichus hamiltoni Horn, P. permundus (Say), Bembidion graciliforme Hayward were the most abundant species collected by pitfall traps and Stenolophus ochropezus (Say), Agonum tenue (LeConte) and Clivina impressefrons LeConte were the most abundant in light trap collections. Differences in the number and abundance of species collected by light traps and pitfalls suggest both methods be used to survey wetlands.
