在查尔斯顿的前磷肥制造厂对由树叶堆肥零价铁（ZVI）、石灰石和豌豆砾石的混合物组成的中试可渗透反应屏障（PRB）进行了30个月的性能评估，PRB旨在通过促进微生物介导的硫酸盐还原和硫化物还原来去除地下水中的重金属和砷。矿物沉淀和砷和重金属吸附。性能监测表明，有效的治疗，铅，镉，锌，镍的浓度。分别高达206 mg L（-1）、2.02 mg L（-1）、0.324 mg L（-1）、1060 mg L（-1）和2.12 mg L（-1），进入PRB，
A 30-month performance evaluation of a pilot permeable reactive barrier (PRB) consisting of a mixture of leaf compost zero-valent iron (ZVI), limestone, and pea gravel was conducted at a former phosphate fertilizer manufacturing facility in Charleston, SC. The PRB is designed to remove heavy metals and arsenic from groundwater by promoting microbially mediated sulfate reduction and sulfide-mineral precipitation and arsenic and heavy metal sorption. Performance monitoring showed effective treatment of As, Pb, Cd, Zn, and Ni from concentrations. as high as 206 mg L(-1), 2.02 mg L(-1), 0.324 mg L(-1), 1060 mg L(-1), and 2.12 mg L(-1), respectively, entering the PRB, to average concentrations of
