Reactive barriers for the remediation of fluoride contamination in groundwater. This project will build the first pilot scale calcite permeable reactive barrier for the remediation of fluoride contamination in groundwater at VAW aluminium. At VAW, fluoride has contaminated groundwater at concentrations up to 3000mg/L, levels far higher than the drinking water guideline value of 1.5mg/L. The barrier design will be based on laboratory work from a previous SPIRT project with VAW and the CIs which h ....Reactive barriers for the remediation of fluoride contamination in groundwater. This project will build the first pilot scale calcite permeable reactive barrier for the remediation of fluoride contamination in groundwater at VAW aluminium. At VAW, fluoride has contaminated groundwater at concentrations up to 3000mg/L, levels far higher than the drinking water guideline value of 1.5mg/L. The barrier design will be based on laboratory work from a previous SPIRT project with VAW and the CIs which has shown that calcite can remove 99% of fluoride contamination from water. The project will prove the technology at the field scale and provide the basis for its application to other contaminants.Read moreRead less
Remediation of Underground Contaminant Source Areas using Nano-scale, Zero Valent Iron and Potassium Permanganate. Land in parts of Australia valued in the hundreds of millions of dollars is currently contaminated by organic compounds to levels unsuitable for human health and safety . At many of these contaminated sites, the contamination is present as pure, separate phase oil that is trapped due to geology or other physical reasons. This remaining oil is a long term source of contamination, a ....Remediation of Underground Contaminant Source Areas using Nano-scale, Zero Valent Iron and Potassium Permanganate. Land in parts of Australia valued in the hundreds of millions of dollars is currently contaminated by organic compounds to levels unsuitable for human health and safety . At many of these contaminated sites, the contamination is present as pure, separate phase oil that is trapped due to geology or other physical reasons. This remaining oil is a long term source of contamination, and is exceptionally difficult to remediate. The proposed research will investigate a novel and highly effective approach to destroying this contamination in the ground, helping to restore the value and utility of the land.Read moreRead less
