Innovative Technologies – Phytoremediation

Langan evaluated phytoremediation at an active manufacturing facility in southern New Jersey to address contaminated soil, sludge, and lagoon sediment, and to provide a site-wide remedy that includes a landfill “phyto-capping” system. This approach, that received preliminary regulatory support under the NJDEP Site Remediation Program (SRP), combines major elements of a conventional landfill cap into a single unit, while simultaneously providing an on-site treatment remedy for impacted media resulting from former wastewater treatment lagoons. The phyto-capping system was designed as a combined landfill cover and vegetative layer to control runoff and inhibit infiltration.
