Gasworks, remedial pilot study

At the Masterton (NZ) gasworks site Geo & Hydro experimented in 1992 with a combination of aerobic and anaerobic biodegradation of PAHs (resp. light and heavy PAHs). The tests were carried out as part of a feasibility study, which needed to resolve the question: to excavate and dump all contamination on the local landfill or to treat in situ.
