The most recent composite analysis for the Savannah River Site, how ever, does not reflect any recent decisions or proposals for Has an Integrated Vision of Monitoring for the Site waste disposition and does not cover the overall site, Although there have been efforts to do so, DOE has not although this concern is important only to the extent that yet fully articulated an integrated vision of monitoring for potential impacts from radioactive materials at various locaeach site. Such an integrated vision would fit together the tions on the site would overlap in space and time.

... To evaluate such ably well at the Idaho National Laboratory but would likely events, an adequate long-term monitoring program needs to provide good results to depths of only a few meters at the include a continuing performance assessment to confirm that Savannah River Site because of the partially saturated claythe site is performing as expected and to point out where rich soils. Alternative geophysical methods include magnetic additional investigation or explanation is needed.
From page 88...
... The geological and hydrological conditions at the Savannah River Site are less favorable for the use of resistivity changes to detect leaks because of higher clay content in the soils and greater interstitial moisture content. With respect to electrical resistivity monitoring, the geological and hydrological conditions at the Idaho National Laboratory are closer to those at Hanford than the Savannah River Site.

... It is, of course, possible to have accessing monitoring data and have populated the databases a good monitoring program without explicitly following the policy, but the programs could be improved in terms of interoperability, meeting the needs of the performance assessment for tank wastes, and coordinating not just within the site but at the margins between sites. Perhaps more 4A 1999 examination of CERCLA five-year reviews (not specific to DOE sites)
