ORIN conducted a pilot test to treat PFAS impacted surface water flowing through collection vaults using BAM filled booms (8” diameter) and pillows (6” thick). The booms were customized to fit the dimensions of the vault for maximum BAM / surface water contact. BAM booms were placed into the vault and passive flow surface water was in contact with the Booms and Pillow for 27 days before initial inlet / discharge samples were collected for laboratory analysis.
