Results of soil, ground-water, surface-water, and streambed-sediment sampling at Air Force Plane 85, Columbus, Ohio, 1996

The U.S. Geological Survey (USGS), in cooperation with Aeronautical Systems Center, Environmental Management Directorate, Restoration Division, prepared the Surface- and Ground- Water Monitoring Work Plan for Air Force Plant 85 (AFP 85 or Plant), Columbus, Ohio, under the Air Force Installation Restoration Program to characterize any ground-water, surface-water, and soil contamination that may exist at AFP 85. The USGS began the study in November 1996. The Plant was divided into nine sampling areas, which included some previously investi gated study sites. The investigation activities included the collection and presentation of data taken during drilling and water-quality sampling. Data collection focused on the saturated and unsatur ated zones and surface water. Twenty-three soil borings were completed. Ten monitoring wells (six existing wells and four newly constructed monitoring wells) were selected for water-quality sam pling. Surface-water and streambed-sediment sampling locations were chosen to monitor flow onto and off of the Plant. Seven sites were sampled for both surface-water and streambed-sediment quality. This report presents data on the selected inorganic and organic constituents in soil, ground water, surface water, and streambed sediments at AFP 85. The methods of data collection and anal ysis also are included. Knowledge of the geologic and hydrologic setting could aid Aeronautical Systems Center, Environmental Management Directorate, Restoration Division, and its governing regulatory agencies in future remediation studies.

Geohydrology and quality of shallow ground water at and near the Old Laurel County and G.C. Singleton landfills, Laurel County, Kentucky

Between 1969 and 1983, solid and hazardous waste was deposited at the Old Laurel County and G.C. Singleton Landfills that were developed on a bench created by strip mining for coal. Water-level data from eight monitoring wells indicate that the general direction of groundwater flow in the shallow aquifer is toward Slate Lick, which is at a lower altitude than the landfills. Analyses of water samples from these wells indicate that the water quality near the landfills is similar to that expected in coal strip-mined areas. The pH of groundwater ranged from 4.6 to 6.2 and indicates acidic conditions. Elevated values of specific conductance in groundwater near the landfills may indicate the effects of landfill leachate or acid-mine drainage. The groundwater samples also contained high concentrations of dissolved constituents commonly associated with acid-mine drainage such as aluminum, iron, manganese, sulfate, and zinc. A relatively high concentration of fluoride, 4.5 mg/L, in water from one well may be related to landfill leachate. Except for 3,4-dichloro-benzoic acid, organic constituents were not detected in the groundwater samples. However, because of the widespread use of chemicals containing 3,4-dichloro-benzoic acid, the source of this constituent in the shallow aquifer system near the landfills cannot be determined.
