permeable reactive barriers

Permeable reactive barriers (PRBs) are structures used to treat contaminated groundwater as it flows through them. They are typically installed underground and made of materials that react with pollutants, breaking them down or capturing them. When contaminated water passes through the barrier, harmful substances are transformed into less harmful ones, improving the water quality. PRBs are often used in environmental cleanup efforts, providing a passive, cost-effective solution to reduce pollution without the need for extensive pumping or treatment systems.
