The EPA's public water system record for WATER AND POWER AUTHORITY-STX in the U.S. Virgin Islands shows no detections of PFAS above reporting levels in federal monitoring from 2024 to 2025. This means PFOA, PFOS, PFHxS, PFNA, HFPO-DA, and other monitored fluorinated compounds were not found in measurable amounts in this system's water sources during that period.
Myth: The Hazard Index for New PFAS Mixtures Indicates a Health Risk
The hazard index is a metric used to estimate the combined potential impact of multiple per- and polyfluoroalkyl substances. However, for the VI public water system, no measurable levels of these compounds were detected, and no health-based violations are recorded. Without detectable concentrations, the hazard index for this area's water system does not imply any actual health concern. It is important to note that this index does not replace direct water testing at a residence.
Myth: Local Sources Like Firefighting Foam or Textile Finishing Contaminate Our Water
While sources such as firefighting foam, textile manufacturing, and landfill leachate are known contributors to PFAS contamination in some regions, EPA's occurrence data for the VI public water system shows no detectable presence of these compounds. This suggests that, at least within the public water supply, these sources have not impacted PFAS levels to detectable extents. However, local variations in source influence mean household testing is necessary to confirm individual water quality.
Myth: Water Sample Depth or Well Type Strongly Changes Expected PFAS Levels
PFAS concentrations can vary depending on whether samples are taken from surface water, shallow wells, or deeper aquifers. The EPA monitoring here uses standard sampling procedures designed to represent the public water system's supply comprehensively. While these results provide a snapshot of source water and treatment effectiveness at the system level, they cannot predict an individual household well's conditions, which can differ based on depth and source. Homeowners should obtain specific testing if concerned about their private water source.
Myth: Larger Households or Seasonal Homes Need Different PFAS Treatment Approaches
Water usage patterns can influence the capacity requirements but do not change the fundamental need for PFAS removal technology if contaminants are present. Because the VI public water system shows no PFAS detections above reporting levels, households must first establish their own water's status before deciding. The Fleck PFAS Forever Chemicals Filter, which ships ready to configure, offers a documented technology to reduce per- and polyfluoroalkyl substances where testing indicates their presence. It can be sized according to household demand whether for large families or intermittent use.
Myth: A Median or Range Value in the EPA Record Predicts Individual Home Water Quality
The EPA's occurrence data lists no detections above reporting levels for any PFAS compounds at four sampling points in the VI public water system. This means the median and range values for PFOA, PFOS, PFHxS, and others are effectively below detectable levels as defined by federal methods. Homeowners cannot infer their specific water conditions from these system-level data alone. Direct water testing for PFAS at the household tap is the only way to obtain precise measurements of these 'forever chemicals'.
What Test Should You Order to Decide on PFAS Treatment?
The single most informative step is to have your own tap water tested for PFAS concentrations using a certified laboratory method capable of detecting compounds such as PFOA, PFOS, PFHxS, PFNA, HFPO-DA, and others at nanogram per litre (parts per trillion) levels. Should measurable PFAS be found, the Fleck PFAS Forever Chemicals Filter system is a documented direct-purchase option designed specifically to reduce these fluorinated substances. Confirming your water quality with testing will settle whether treatment is warranted for your household's peace of mind.
