Mayor: RO pilot removed PFAS compounds below EPA MCL; litigation limits further disclosure
Summary
Mayor James Stewart said a multi-technology reverse-osmosis pilot removed PFAS to below the EPA standard but added that ongoing litigation prevents the city from releasing further details about the pilot.
Mayor James Douglas Stewart Jr. told the Irondale City Council that a 15-week reverse-osmosis (RO) pilot study in the city's water system successfully removed PFAS compounds to concentrations below the EPA maximum contaminant level (MCL) specified in the discussion.
The mayor said the pilot tested two different RO technologies in conjunction with multiple manufacturers and demonstrated a pretreatment train and RO design that could meet the EPA MCL. He cautioned the public that the city cannot provide additional information at this time because of ongoing litigation relating to PFAS in the municipal water system.
The mayor's remarks were given as part of a broader informational report on city operations and upcoming events; he referenced the pilot study as a potential permanent treatment option under active review by staff and consultants.
The mayor also referred residents to notices received via water or garbage bills for other customer communications and said future updates would be limited while litigation is pending.
