Re: Remediation Waste -Reply




Asphalt batching is commonly used in the northeast as a "remediation" 
technique for petroleum contaminated soil.  I believe the recycled material 
most often meets the specifications for an aggregate base.  In the NE, 
asphalt batching is usually the most economical remediation (recycling) 
 option for petroleum contaminated soil, usually priced at about $20 - 
25/ton, not including transportation.  As far as I can tell, asphalt 
batching for petroleum-contaminated soil is not used here in the midwest b/c 
landfill prices are so inexpensive - I think in the $10/ton range.

Using the contaminated for an aggregate base?
That is a very interesting concept.  Does anyone
have an example.

I realize this isn't the typical remediation project to
which you refer...

Groundwater remediation projects seem to have
businesses cleaning water to
relatively high standards.  Typically the water is then
discharged (NPDES or
POTW).  In some cases there is a concern that the
remediated water may be a
listed hazardous waste (depending on the source
of contamination).

The hazardous waste issue, if applicable, can be
addressed by pursuing
"de-listing" or "de-wasting" procedures (both state
and federal?).  Too bad
this process reportedly has the reputation of NOT
being very user friendly.
If not removed from the waste category liability
could be a concern.

Provided the water is "clean", direct reuse of
remediated water for cooling,
cleaning, as a process water, and perhaps other
uses could be considered in
many cases rather than accepting discharge as the
only option.

In typical clean-up projects developing technologies
seem to allow for more
cleaning and reuse of contaminated soils.
Economics will decide this
option.  For soils or other wastes
you're probably right that segregation for
economical disposal is the best
option, prevention aside.  Reuse and/or processing
options might be a long
shot pending the type of contamination and
potential use options.  Wastes
which meet acceptable gradation specifications
may find use as aggregate for
use in concrete, asphalt, road construction, etc. if
contamination is
limited to low TPH levels, low level non-leachable
constituents...pending
local regulations.
