[en] In-situ injection of chemical remedial amendments for land / groundwater contamination has a range of benefits. It can eliminate the need for expensive excavation and can be done close to buildings, reduce total costs, shorten time frames and produce smaller carbon footprints. Coffey Environments has acquired the only licence in Australasia for Wavefront Primawave pulsed injection technology, which has been used at US brownfield sites, with a 75 per cent decrease in injection points and more than 40 per cent savings of the remedial costs.
