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)
