BCEE (bis-2-chloroethyl ether) treatment 2

[mdszj]

I am trying to track down any info or case histories on whether BCEE can be treated in-situ using oxidation by ozone, peroxide, or any other method. This material is a partially water soluble contaminant at a landfill site I am working on. I have already had lit searches done with little promising results.

mdszj - sorry no direct case studies, but some info nevertheless:

According to the Federal Remedial Technologies Roundtable, in situ chemical oxidation is an appropriate technology for remediation of halogenated SVOCs due to relatively indiscriminate and rapid rate of reaction with reduced substances.

For specific examples, you may want to try the Interstate Technology Regulatory Cooperation (ITRC):

http://www.itrcweb.org

They publish case studies in their guidance documents; try the 2001 ISCO document available for free download. ITRC continually compiles case studies, so the instructors for the ISCO course may have some newer ones completed since the manual has been published. They been very helpful and responsive to me in the past if you want to try them directly. Thomas Stafford of Louisiana DEQ can be reached at stafford@ldeq.org. Wilson Clayton of Aquifer Solutions can be reached at wclayton@aquifersolutions.com

Good luck

Hello mdszj:

We have looked at one site that treated BCEE in situ using Fenton-like chemistry (by others). Bench and field testing indicated that in situ oxidation of BCEE may be acheived. A cursory look at the structure of BCEE would imply that a more powerful oxidant, such as ozone- or peroxide-based chemistries, would likely be necessary as compared to permanganates. Mineralization ranged from 50 to 80% therefore additional bench-testing may be prudent.

hello Bkmorange

Thanks for the info on oxidation of BCEE in situ, sorry I did not get on this site sooner to see your reply. By any chance do you think it would be possible to get access to the case info/data you mentioned, or at least part of it, or a sanitized version? I am interested in the H&S aspects of the treatment as well as its effectiveness.

Sounds like a directly applicable case history, especially since BCEE is not your "typical" contaminant.
