    Focazio, M. Where the shot was probably up-dip A and Hthe bedrock values may be too shallow. The flow time was estimated to be 2 yr. Sam- ples for analyses of iron and manganese were filtered through a 0.

    Modern marine sediments as a natural analog to the chemically stressed environment of a landfill, J. For example, sand or clay lenses may occur in either environment, and channel deposits of different ages may truncate the units. As could be expected, then, temperature profiles for lines E through G Fig. The information has not been updated.

    Other effects of the changes in the transmissivity and vertical leakance values possibly exist that are not apparent without more extensive quantitative analysis. Additional water is internally supplied and removed during the same pumping periods as flow into and out of storage. Differences in simulated water levels probably result largely from changes in transmissivity and vertical leakance values. Finally, the amounts of reactants and products for the chemical reactions were calculated to balance the abundances of species.

Letter above profile indicates test site. Aquifer transmissivities and lateral extents represented by the layers in the revised model appear similar to those of the original model Harsh and Laczniak,figs. Aromatic hydrocarbons are the most prev- alent of the compounds definitely identified.

U.S. Geological Survey ground-water studies in Delaware book addition, the polygon coverage includes ancillary hydrogeologic information that is not used by the model, such as aquifer and confining unit elevations and thicknesses, and provides a means to examine and analyze different aspects of the hydrogeologic framework.

However, to achieve this retardation, pumping of water for supply has been curtailed and a significant amount of un- contaminated groundwater is wasted by pumping the recovery wells.

Kunath, C. Within this zone the pH at any one site has changed little from to ; the average change in pH is 0. As the plume migrates through the aquifer, these processes change.

If the flow is extremely slow in the aquifer relative to reaction rates, the plume will be attenuated more rapidly and the boundaries between zones may be noniden- tifiable.

Page Share Cite Suggested Citation:" A test hole at a site midway between F and G, chosen from temperature and seismic data discussed below, should define whether the main channel with its basal gravel is three miles 5 km wide or is instead two narrower channels. Herbicides were detected in most water samples, which were collected to coincide with runoff events following herbicide application, but antibiotics were detected in only 1 percent of the samples.

Geological Survey Professional Paper K, 81 p. Nicholson, R. For example, the presence of low-velocity zones, particularly noticeable on the seismogram for H, would cause calculated bedrock levels to be too deep. These estimates are based on an evaluation of aquifer transmissivity, measurements of the hydraulic gradient in the aquifer adjacent to the landfill, and estimates of rainfall entering the landfill.
