Results and discussion
Any other information on results incl. tables
Tributyl phosphate was identified in trench leachates from the West Valley and Maxey Flats sites. 0.16 mg/L of Tributyl phosphate was found in trench 19 in the Maxey Flats trench leachate samples. Whereas, Tributyl phosphate was found in trench 3, 5 and 8 in the West valley trench leachate samples with a concentration of 0.35, 0.76 and 0.86 mg/l respectively.
Applicant's summary and conclusion
- Conclusions:
- Tributyl phosphate was found to leach from the radioactive waste disposal sites and enter the trench leachate samples.
- Executive summary:
Several trench leachate samples collected from commercially operated low-level radioactive waste disposal sites at Maxey Flats, Kentucky and at West valley, New York were analysed for organic constituents including Tributyl phosphate. These were analysed by gas chromatography and mass spectrometry.
