Comment on VENM Classification by Site Remediation

Without seeing the actual analytical reports of the VENM it is difficult to categorally answer yes or no to your questions. Generally, the risk of contaminating a site through using backfill material classified as Virgin Excavated Nateral Material (VENM) is minimal. In the situation where the VENM has natural elevated metal levels there are a couple of things that you can do to assist you deciding whether to import the VENM or not, such as:
* Compare the levels of analytes within the VENM to the guideline parametres allowed onsite.
* Examine the leachability of the metals within the VENM through TCLP analysis.
* Collect samples from the groundwater prior to importing the fill to confirm what the background levels of the metals of concern are within the groundwater.
* Source material from another location and do not import it onsite. VENM is generally always available.

I hope this helps. If you need further assistance please call and I am always happy to have a chat.

Using VENM as backfill soils:
What is the risk of contaminating groundwater by using imported, classified, VENM which has higher background metals concentrations compared to that of the receiving site. For example, a quarry which we’re sourcing VENM from has high concentrations of naturally occurring background metals. We’d like to use this VENM to backfill an excavation which the depth of the excavation is below the water table. If we backfill with this VENM, will the groundwater become impacted with dissolved metals and is this considered polluting under the POEO Act? And is this considered soil contmaination as well?

Although soil testing is valid as astm standard, soil conditions maybe change when the time passing.

I think so that soil investigation task is very important for contruction and environment control.
