Abstract

Landfills can be a source of groundwater pollution if they are not properly designed to reduce leachate pollution. Leachate produced by wastes is carried by rainwater through infiltration and by groundwater flow, which can cause contaminants to enter surrounding groundwater wells. The remediation of groundwater contaminated with iron by landfill leachate can be accomplished through phytoremediation. This literature review aims to investigate different plant species that have potential for phytoremediation of iron- contaminated groundwater at the TPA Keputih landfill site in Surabaya. Kayu Apu (Pistia stratiotes) was selected for the case study of remediation of iron contaminated groundwater at the TPA Keputih landfill site. Calculations show that on a household scale, 84 stems of Kayu Apu and a residence time of 7 days are required to remove excess Fe in groundwater to meet water quality standards
