Brunswick County’s Northwest Water Treatment Plant reverse osmosis project receives national recognition in American Water Works Association publication
BOLIVIA, N.C. – Brunswick County’s ongoing work to remove per- and poly-flouroalkyl (PFAS) substances from our drinking water was recently featured as the cover story in the American Water Works Association’s Journal AWWA.
The article published this May focuses on Brunswick County’s efforts with consultants at CDM Smith to research and test several advanced water treatment technologies such as low-pressure reverse osmosis, granular activated carbon and ion exchange following the discovery of PFAS compounds like GenX in the Cape Fear River in 2017.
Following a desktop analysis, low-pressure reverse osmosis was identified as the most effective option to remove a wide variety of PFAS compounds and other possible contaminants of concern. It is also considered the most resilient in the event of contaminant spikes from upstream dischargers.
A pilot study using low-pressure reverse osmosis treatment at the plant further confirmed the treatment system’s effectiveness at removing these compounds from water, most of which are currently unregulated at the federal and state level. The Brunswick County Board of Commissioners unanimously approved the selection of low-pressure reverse osmosis treatment in 2018.

Construction began in June 2020 to both expand the plant’s capacity to support the county’s growth and install the reverse osmosis treatment system. The project is now 20% complete and the first set of reverse osmosis treatment systems are expected to become operational in June 2023.
