A proposal to manage toxins in Australia’s Kendall Bay would bury contaminated silt under a 5 hectare blanket of geotextile. The 40-metre-wide geotextile strips would be installed over 56,000 sq m of the bay and weighted down by 400 mm of basalt rock. The combination would of materials would stop boat propeller activity from disturbing the soils in the lake bed. The Mortlake gasworks plant had operated along the shore for 100 years. The new remediation plan is being pushed by a developer who wants to open a 172-berth marina.
