Sustainable solution to groundwater and soil contamination

01 August, 2011 by

Coffey Environments has over 15 years of experience in the injection of chemical amendments into contaminated groundwater and lithologies across a broad range of contaminated sites throughout Australia. The company recently acquired the only licence in Australasia for Wavefront Primawave pulsed injection technology that has been demonstrated to improve amendment injection efficiency.

Sustainable remediation of LNAPL in fractured basalt

23 February, 2011 by William Gary Smith, PE*

Since late 2007, URS Australia (URS), on behalf of a major oil company, has managed the continuing investigation and remediation of a petroleum fuels pipeline release site in Victoria. Sustainability principles and measures have been a major feature of the remediation. The release was initially believed to be short term and consisted of primarily unleaded petrol, jet fuel, and diesel fuel from a multi-product pipeline. The pipeline was promptly repaired and contaminated fill soil from the immediate vicinity of the release was removed and disposed of off site. One of the most significant challenges at this site is determining the extent and techniques for removal of light non-aqueous phase liquids (LNAPL) within regulatory mandates and time lines.

Exair Chip Trapper vacuum for contaminated liquid

14 January, 2010 by

Exair’s Chip Trapper offers a fast and easy way to clean solids such as chips, swarf and shavings out of used coolants and other liquids. The unit vacuums the coolant or liquid that is filled with debris into the included 208 L drum, trapping all the solids in a re-usable filter bag. With a turn of the flow valve, clean liquid pumps back out. Expensive coolant that used to last only six weeks can now last longer with regular use of the Chip Trapper. The unit is suitable for use on machines with sumps, parts washers, tanks and storage containers.
