Maintaining of good quality of groundwater is of great public interest worldwide.
However, this source is highly vulnerable to different pollution sources such as
industry, mining, irrigation, and so on. The pollution problems are more often
observed in Karst areas where large amounts of fresh water can be contaminated in a
short time. The application of an in situ technique for remediation of contaminated
groundwater is highly recommended due to its simplicity of performance and
economic benefit. Among in situ techniques, the permeable reactive barrier is the
most attractive method as it allows for using different materials in the barrier for
remediation of contaminated groundwater. Materials for PBR must demonstrate
good contaminant binding properties, the ability of their retention, excellent
hydraulic properties, satisfactory mechanical properties for safe performance, and
ensure a smooth flow through the barrier without disturbing the natural flow.
Nowadays the researc...h is focused on investigation of different natural materials to
protect the environment, due to their low cost and availability in nature in large
quantities. The purpose of this work is to investigate the efficacy of various natural
materials such as natural and iron-modified zeolite, apatite, concentrated apatite,
kaolin and raw bentonite to remove heavy metals (lead and cadmium) from
contaminated groundwater using the in situ PBR. The batch test involves sorption
experiments followed by leaching experiments. In sorption experiments, the
amounts of metal removal by different sorbents were evaluated for cadmium and
lead from simulated wastewater with similar initial metal concentrations. The
leaching experiment included evaluation of metal retained by the saturated sorbents
in ultrapure water with adjusted pH values at 2.98 and 6.07. Additionally, pH values
of solutions were recorded during both experiments. Based on obtained results, the
sorbents that provide the optimal metal removal and their retaining from the
contaminated groundwater were selected.
