Soil samples from two low-level radioactive waste facilities belonging to the University of North Carolina at Chapel Hill were evaluated for their tritium content. The interstitial soil water and associated tritium activity was separated from the soil by distillation at high temperatures. Condensed water from the soil samples was then counted in a liquid scintillation counter. At the Horace Williams Airport site, no detectable tritium activity was found. At the Mason Farm site, no tritium activity was found off site but trace amounts (less than 30 pCi/g of soil) were found in soil between individual burial pits inside the site boundaries. Soil sampled from the pits at the Mason Farm site had tritium values that ranged from non-detectable to 735 pCi/g of soil.
