BIO PLUGS

Bio Plugs are an innovative, low intervention, in situ remediation technique developed, patented, and applied by PGI for both saturated and unsaturated contaminated soils and sludge.  Bio Plugs delivered contaminant degrading, naturally occuring microbes to areas for groundwater and soil remediation, efficiently and economically treating contaminats by eliminating costly site deconstruction.  Bio Plugs are small microbe bioreactor  constructed using slotted pipes containing Media that are sealed at each end to hold the microbes in place.

During a Bio Plug installation the contaminated zone is mapped and the Bio Plugs are strategically inserted into the ground to treat contaminated soil. Once the Bio Plug is inserted into the contaminated zone, water is introduced into the plug through a pressure gradient using compressed air; this process delivers the microbes to the contaminated zone for treatment.

The cost savings associated with the Bio Plugs can be significant compared to other bioremediation clean up methods.  Bio Plugs have been especially useful in gas station and truck stops where existing building or equiment limit of prohibit excavation of the contaminated soils.  They have also been used in situations where the contaminants are spread over a large area such as oil or gas pipelines.
