Book excerpt: To minimize movement of tritium into surface waters at the Mixed Waste Management Facility at the Savannah River Site, tritium contaminated seepage water is being retained in a constructed pond and used to irrigate forest acreage that lies above the pond and over the contaminated groundwater. Twenty five-year potential evapotranspiration and average precipitation are 1443 mm/year and 1127 mm/year, respectively, for the region in which the site is located. Management of the application of tritium contaminated irrigation water needs to be evaluated in the context of the large amount of rainfall relative to evapotranspiration, the strong seasonality in evapotranspiration, and intraannual and inter-annual variability in precipitation. A dynamic simulation model of water and tritium fluxes in the soil-plant-atmosphere continuum was developed to assess the efficiency (tritium transpired/tritium applied) of several irrigation management strategies.
