The modified L/N ratios also showed a statistically significant difference between the means of the bores impacted by municipal waste versus those impacted by non-putrescible waste (p = .003), indicating they are a much more sensitive indicator of both the existence and type of landfill leachate impact on groundwater than previously reported. This new index may prove particularly useful in complex urban areas where multiple potential contamination sources exist, and land use histories are either unknown or complicated. Capsule: Conventional methods for leachate detection in groundwater surrounding legacy landfills have been analysed and further developed via the inclusion of perfluoroalkyl acids, to better understand contaminant sources, fate and transport.]]> Thu 08 Feb 2024 10:42:49 AEDT ]]> A method for separation of heavy metal sources in urban groundwater using multiple lines of evidence https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:42848 Mon 05 Sep 2022 15:12:20 AEST ]]>
