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.

  • This report describes the results of vapor samples taken from the headspace of waste storage tank 241-SX-109 (Tank SX-109) at the Hanford Site in Washington State. Pacific Northwest National Laboratory (PNNL) contracted with Westinghouse Hanford Company (WHC) to provide sampling devices and analyze samples for inorganic and organic analytes collected from the tank headspace and ambient air near the tank. The analytical work was performed by the PNNL Vapor Analytical Laboratory (VAL) by the Tank Vapor Characterization Project. Work performed was based on a sample and analysis plan (SAP) prepared by WHC. The SAP provided job-specific instructions for samples, analyses,more » and reporting. The SAP for this sample job was {open_quotes}Vapor Sampling and Analysis Plan{close_quotes}, and the sample job was designated S5048. Samples were collected by WHC on August 1, 1995, using the Vapor Sampling System (VSS), a truck-based sampling method using a heated probe inserted into the tank headspace.« less
