Manufactured Gas Plants

Effective Remediation

Manufactured gas plant (MGP) sites provided gas to many towns from the early 19th century to the late 20th century. Toxic residues that resulted include coal tar as well as contaminated soil, sediment, and groundwater, which are still present today. Our product manufacturer offers cost-effective and innovative products that allow us to successfully remediate former MGP sites for redevelopment. 

Permeable Reactive Barrier

Utilization of our products as a Permeable Reactive Barrier (PRB) is an effective way to control the source of contamination by treating groundwater as it flows through it.

In Situ Solidification/Stabilization

Our product is an effective way to attract and hold organic compounds found in contaminated groundwater and sediment. Moreover, our product is an effective stabilization agent that allows Portland cement to cure properly.

Sediment capping

Coupling our product or granular activated carbon (GAC) with a Mat provided by our manufacturer is an effective means for to remediate sediment. 

A Mat is a patented permeable composite material consisting of reactive material(s) encapsulated in a non-woven core matrix bound between two geotextiles. The upper geotextile is a needle-punched, non-woven fabric that is heat-laminated to a matrix of nonwoven fibers needle-punched into a woven geotextile.
