摘要：

This study contains laboratory, field and numerical methodology to determine the feasibility and performance of a permeable reactive barrier (PRB) utilising low cost recycled concrete aggregates for the remediation of acidic groundwater in acid sulfate soil (ASS) terrain. The PRB was installed in the Shoalhaven Floodplain about 100 km South of Sydney (Australia), in an area where acidic groundwater generation from pyritic soil poses a severe environmental and socio-economic problem.
