PCB Levels

[Peter Strauss <pstrauss@igc.org>]

I am doing research about establishing cleanup standards at a DOE 
Superfund site. 

Does anyone have experience with PCB cleanup levels that are stricter 
than TSCA (25 ppm, 1 ppm), given concerns about dioxin/furan and 
co-planars.

If one were going to sample the PCBs for the above constituents, what 
detection limits would be required? How many samples of a localized spill 
would be necessary?

Also, does anyone have information on the status of remediation 
technology, other than incineration, for destruction or containment of 
PCBs, and dioxins/furans.

Any experience at DoD facilities would be most helpful.

Thanks,
Peter Strauss
