About

Loureiro designed and implemented a pilot study for enhanced aerobic bioremediation (EABR) using pure oxygen injection as an alternative remedy. The pilot demonstrated that the EABR barrier effectively promoted biological destruction of benzene and chlorobenzenes, and immobilization of arsenic.  Based on the success of the pilot, Loureiro was part of the design and performance evaluation team for the Phase 2 system, which consisted of a 1,000-ft long, 50-ft wide by 80-ft deep oxygen injection zone.  The use of biosparging, in lieu of groundwater extraction and treatment, is expected to save more than $10 million over a projected 30-year period.
