High resolution seismic reflection applications in ground water monitoring design
The bedrock underlying the Rocky Flats, Golden, Colorado is comprised of claystone, siltstone and sandstone that were deposited by a complex fluvial system. Because of the heterogeneities inherent in such a complex stratigraphic system, monitoring networks should be based on an accurate reconstruction of the depositional system. The inherent costs for such a network prompted an evaluation of alternative methods to characterize the subsurface geology. Shallow high resolution seismic reflection was modeled and field tested in light of remedial investigation objectives to assess ground water contamination. In addition, paleochannel morphologies, facies changes, and other stratigraphic and structural features not evident from borehole correlations were indicated. The current stratigraphic and depositional models are being re-evaluated to incorporate this preliminary seismic information. A conceptual three-dimensional geologic model, in addition to previously collected contaminant data, is being used to develop the monitoring networks at the Rocky Flats Plant. 6 refs., 13 figs.
