Loureiro provides in-situ bioremediation services at a facility in California. Earlier phases of the project involved data collection, pilot testing, and developing a remedial strategy for multiple contaminant plumes. The project objective is to accelerate remediation of chlorinated volatile organic compounds in site groundwater to the point where the plumes can naturally attenuate without containment. The site poses significant technical challenges, given its setting in and around a densely housed neighborhood with heterogeneous soils and close proximity to other environmental sites. First phase of ISAB was implemented in 2011 achieved favorable results; TCE concentrations decreased by greater that 90% during one year of remediation.
