The project team worked with the city and multiple agencies to coordinate design-build implementation of granular activated carbon (GAC) treatment technology for five groundwater supply wells at four separate sites. The project will ensure long-term compliance with state drinking water standards limiting levels of Trichloropropane (TCP), a groundwater pollutant that has been linked to cancer.
Due to the wells’ differing locations and connections to the city’s water system a decentralized system was employed. The three GAC systems were added adjacent to their respective wellheads, all of which were in close proximity to residences. GAC treatment serving two additional wells was located at a central arsenic treatment facility (CATF) in a mixed commercial residential area.
