Results of physical and chemical analyses of sediment and water collected
near a closed municipal landfill at Norman, Oklahoma are presented in
this report. Sediment analyses are from 40 samples obtained by freeze-shoe
coring at 5 sites, and 14 shallow (depth <1.3 m) sediment samples.
The sediment was analyzed to determine grain size, the abundance of extractable
iron species and the abundances and isotopic compositions of forms of
sulfur. Water samples included pore water from the freeze-shoe core,
ground water, and surface water. Pore water from 23 intervals of the
core was collected and analyzed for major and trace dissolved species.
Thirteen ground-water samples obtained from wells within a few meters
of the freeze-shoe core sites and one from the landfill were analyzed
for major and trace elements as well as the sulfur and oxygen isotope
composition of dissolved sulfate. Samples of surface water were collected
at 10 sites along the Canadian River from New Mexico to central Oklahoma.
These river-water samples were analyzed for major elements, trace elements,
and the isotopic composition of dissolved sulfate.
