What Laboratory Test Reports Show About PFAS Concentrations

Measured Units and Decimal Precision

Test reports from government monitoring list PFAS levels in nanograms per litre (ng/L), the same as parts per trillion (ppt). Reporting limits are set very low, often to four decimal places, such as 0.004 µg/L (which corresponds to 4 ng/L), because these substances occur at extremely low concentrations in water sources.

A reported value below the detection limit means the compound was not measured above a very low threshold, not that it is absent or present at zero. Precision at four decimal places shows the sensitivity of current instruments used in federal surveys.

Which PFAS Compounds Have Federal Maximum Contaminant Levels (MCLs) as of 2024

Compounds with Established Federal MCLs

• PFOA (Perfluorooctanoic acid) – MCL of 4.0 ng/L
• PFOS (Perfluorooctanesulfonic acid) – MCL of 4.0 ng/L
• PFHxS (Perfluorohexanesulfonic acid) – MCL of 10 ng/L
• PFNA (Perfluorononanoic acid) – MCL of 10 ng/L
• HFPO-DA (Hexafluoropropylene oxide dimer acid) – MCL of 10 ng/L

Compounds Without Federal MCLs Yet

• PFBS (Perfluorobutanesulfonic acid)
• PFHxA (Perfluorohexanoic acid)
• PFPeA (Perfluoropentanoic acid)
• PFBA (Perfluorobutanoic acid)
• PFHpA (Perfluoroheptanoic acid)

These unregulated fluorinated compounds are monitored for research and potential future standards but do not currently have federal MCLs.

Questions Households Face Compared to Commercial or Industrial Operators

What Households Should Consider

• Whether their water system has detected PFAS compounds above reporting levels in routine federal monitoring.
• How to obtain a specific test of their own well or tap water to know actual individual concentrations.

Additional Questions for Larger Water Users

• Monitoring for daily intake volumes and treatment capacity to comply with regulations and maintain business continuity.
• Managing PFAS in process water or high-volume demand that might differ from residential usage patterns.

How Treated Water Changes at the Tap with Autotrol PFAS Forever Chemicals Filter

Reduction of PFAS Compounds

The Autotrol PFAS Forever Chemicals Filter uses advanced technology to reduce a broad range of per- and polyfluoroalkyl substances in household water. By filtering water before it reaches taps and appliances, it diminishes the presence of these fluorinated compounds, even when detected near reporting levels.

Impact on Household Water Quality

Filtered water improves confidence in daily use for drinking, cooking, and cleaning by minimizing trace levels of "forever chemicals." This technology ships ready to configure for in-home water treatment needs.

Pathways of PFAS Entry into Groundwater and Distribution Systems in Coffee County

Sources in the Region

PFAS compounds can enter groundwater locally through industrial discharges, firefighting foam residues, wastewater effluent, and atmospheric deposition. In Coffee County, the Enterprise Water Works system draws from groundwater sources, where low-level detection reflects widespread environmental presence rather than isolated contamination.

Movement Through the Distribution System

Once in the source water, PFAS can persist through treatment plants and into the distribution network because of their chemical stability. Ongoing monitoring by federal and state agencies helps track any changes over time.

In summary, Enterprise's public water supply monitoring shows no PFAS compounds detected above reporting limits nor above federal maximum levels. Households wishing to understand their specific water quality should pursue direct testing. When additional reduction is desired, the Autotrol PFAS Forever Chemicals Filter provides a documented approach to lowering fluorinated compounds at the tap.
