into the groundwater at the sourceof contamination. Injected air also promotes biodeg-radation in the aquifer and in the vadose zone(Bioventing).Groundwater with high levels of dissolved iron, cal-cium and other inorganic constituents must bepretreated before the spray aeration module to re-duce maintenance costs. A complete ...

Easy to mix with standard rig equipment ? Helps allow hole re-entry, can be drilled out Typical Properties • Slurry weight • Hydrostatic gradient • Total active ...
Executive Summary Dense, nonaqueous-phase liquid (DNAPL) contaminants are a challenge to characterize and remediate at many sites where such contaminants have entered the aquifer due to past use or disposal practices. Chlorinated solvents, comprised of chlorinated volatile organic compounds ...
ACCU-VIS & BELLE CRUMBLES blends a granular bentonite with a consistently controlling liquid polymer to form a slurry that provides an economical way to seal and grout boreholes, well casings, and earthen structures. Once set, the slurry forms a complete grout seal with low ...
