Re: Remediation Waste



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.
