Tritium contaminated concrete rubble from the 232-F Tritium Facility was disposed in the Slit 1 Trenches 1 and 2 in 1997. A Special Analysis (SA) has been performed to evaluate any impact this disposal may have on the groundwater. The SA assumed that the disposed concrete rubble was fully saturated at the time of disposal, however if the concrete was less than fully saturated, migration of tritium out of the concrete would be slower than under fully saturated conditions. Therefore if the concrete at disposal was less than fully saturated, the PA assumption of full saturation would be a conservative assumption. In order to evaluate whether the PA assumption resulted in a conservative analysis from the standpoint of the concrete saturation, concrete rubble samples were collected from various facilities being demolished at the Savannah River Site (SRS) and evaluated for in-field moisture content, absorbable moisture, and water exchangeable porosity. The purpose of this task was to collect concrete rubble samples from various demolished SRS facilities for the purpose of determining in-field moisture content, absorbable moisture, and water exchangeable porosity. Since moisture content testing for concrete rubble is not typical, existing ASTM Standards were reviewed for method and procedure development.
