INQUIP has considerable experience
working on hazardous and toxic waste sites. These projects either involve
the remediation or closure of the sites and may use one or more of our
specialty geotechnical techniques. Slurry cutoff walls are often used to
contain contaminated groundwater and prevent the horizontal migration of
leachates, or prevent the infiltration clean groundwater. Collection/extraction
trenches constructed by the Bio-Polymer technique are used to collect and
extract leachate. Other INQUIP techniques such
as grouting, HDPE curtain walls, and stabilization have also been successful
used to contain pollution.
Proper planning and engineering are a requirement on all pollution containment
projects. The chemistry of the leachate may effect the cutoff wall backfill
mix and the bentonite slurry and these are normally tested prior to construction
for compatilility. Groundwater flow may change after the installation of
a slurry wall, so groundwater modeling is often used to evaluate groundwater
control schemes. With proper planning, containment is often the most economical
and lowest risk approach for pollution control.
Combinations of geotechnical techniques
are commonly used to minimize costs and optimize the construction of a
pollution containment. The combination of a slurry cutoff wall with groundwater
wells or collection trenches, capped with a barrier membrane, is often
the most acceptable and economical method for groundwater containment.
When space is limited, groundwater barriers and extraction can be combined
in a single trench fitted with a HDPE curtain wall, aggregate, and extraction
wells or piping. On difficult sites, problem soils or sludges may be stabilized
to reduce the generation of leachates, and then contained with a slurry
cutoff wall and less extensive groundwater controls.
INQUIP specializes
in creating innovative and cost effective systems and combinations of techniques
for pollution containment.
