thread193-39462: dry cleaning solvent (PCE) remediation
While digging at a construction site, we encountered soil contaminated with 1% PCE,at a depth of 16 feet. Soil is wet but no groundwater accumulation in the cavity. Since time is of the essence and it is not a regulated site, can we add hydrogen peroxide with ferrous sulfate in the cavity, before closing it? if yes, what would be the quantities. Any help will be greatly appreciated.

RE: Remediation of PCE in Soil
I strongly urge you to contact someone with experience in this area.
In No. CA, the screening level for PCE in deep soil is 0.7 or 17 mg/kg (depending on whether or not the gw affects drinking water). You have many magnitudes greater than that.
Have you determined the extent of the contamination? How do you know it isn't affecting gw?
Unless you can answer those questions, I can't see how you can consider closing the excavation.

If not, BJindal, I appologize in advance. Can a moderator please close this thread, as greenone posted the appropriate response.

I'd never think this a troll post. However, if you want some measure of assistance, you'd need to provide more information. That said, until you get the local/state environmental agencies involved, what you get from this site will just be speculation.
These can be interesting assignments. That said, it's not quite as simple as dumping in some hydrogen peroxide. You may find air-sparging more effective, but this is all moot until you identify the source.
Good luck.
