Title: Potential Waste Tank Headspace Concentrations of DDE and 1-Naphthylamine

Abstract

Recent studies conducted for the Hanford Waste Treatment Plant (WTP) found that the centrifuged solids from tanks 241-AW-101, 241-AN-107, and 241-C-104 contained two carcinogenic chemicals, 1-naphthylamine and 2,2-bis(4-chlorophenyl)-1,1-dichloroethene (DDE), that had never been detected in tank headspaces. This report estimates the potential headspace concentrations associated with these two compounds. The calculation was based on a comparison of headspace concentrations and waste concentrations for sixteen other organic compounds in the passively-ventilated tank 241-C-104. An approximate relation was found between the compounds? solubilities in water and their headspace concentrations. The relation was used to estimate the 241-C-104 headspace concentration that would result from the maximum measured waste concentrations of DDE and 1-naphthylamine. On the basis of the assumptions made in this report about organic compound transport and equilibration, the DDE concentration was estimated at well below one part per trillion, below standard analytical detection limits. However, 1-naphthylamine could potentially be present in the headspace of a passively ventilated tank at the 30 ppb level.
