PFAS Forever Chemicals in Inverness, FL: Citrus County Drinking Water Risks
Per- and polyfluoroalkyl substances — better known as PFAS or forever chemicals — have become one of the most discussed environmental health topics in Florida over the past decade. These synthetic compounds don't break down in the environment or in the human body, and they've been found in water systems across the state. For Inverness residents and the broader Citrus County community, understanding PFAS exposure risk requires looking at both the municipal water supply and the broader regional groundwater picture.
What Are PFAS and Why Do They Matter in Inverness?
PFAS is an umbrella term for thousands of man-made chemicals used in nonstick cookware coatings, food packaging, firefighting foam (AFFF), stain-resistant fabrics, and countless industrial applications since the 1940s. The two most studied compounds — PFOA and PFOS — were phased out of U.S. production but persist globally in soil and water because they don't degrade naturally.
The EPA finalized its first-ever enforceable limits for PFAS in drinking water in 2024, setting maximum contaminant levels for PFOA and PFOS at 4 parts per trillion — a remarkably low threshold that reflects how potent these compounds are at trace levels. Health effects linked to long-term PFAS exposure include elevated cholesterol, thyroid disruption, immune system effects, pregnancy complications, and increased risk of certain cancers.
Inverness draws its municipal water from the Floridan Aquifer. While the deep Floridan Aquifer has historically been considered relatively protected from surface contamination, PFAS research in Florida has found these compounds in surficial aquifers and some Upper Floridan zones near known contamination sources. Citrus County's water utility conducts testing per EPA requirements, and results are published in the annual Consumer Confidence Report.
Regional PFAS Sources Near Citrus County
- Military installations and airports: AFFF firefighting foam used at airfields is one of the primary sources of PFAS groundwater contamination nationally.
- Biosolids land application: Agricultural and municipal biosolids used as fertilizer can contain PFAS. Land application practices across Central Florida have contributed to PFAS detection in some private wells.
- Legacy industrial sites: Older industrial sites statewide have contributed to broader groundwater PFAS loading in Florida.
Private Well Owners: A Distinct Concern
Inverness has a mix of residents on city water and those on private wells in surrounding rural areas. Private well owners face a fundamentally different situation: their wells receive no treatment at all, and no regulatory monitoring. If PFAS are present in the shallow aquifer near a private well, the homeowner has no way of knowing without independent testing.
Standard Treatment Doesn't Remove PFAS
Conventional water treatment — including chloramine disinfection — does absolutely nothing to remove PFAS. These chemicals are not affected by chlorine, chloramine, UV treatment, or standard softening. Even many popular consumer pitcher filters provide little to no PFAS reduction.
The treatment technologies that effectively reduce PFAS include: reverse osmosis (90–99% PFAS rejection, the most effective point-of-use option), certified activated carbon block filters (effective for longer-chain PFAS with proper contact time), and PFAS-selective ion exchange resins (an emerging technology increasingly available in residential systems). For Inverness households with private wells in Citrus County, comprehensive water testing is essential before selecting any treatment system.
