Data from Floyd County’s public water system in Rome (GA1150001) reflects measurements of PFAS in surface-sourced drinking water. This information pertains to the entire system and not individual household taps or wells. To know the exact PFAS levels at your home, testing your water is essential. This checklist guides your understanding of the area’s PFAS profile and treatment choices.
Why PFOA and PFOS Are Measured in Nanograms per Liter and What Four Decimal Places Mean
Nanograms per liter (ng/L) equals parts per trillion (ppt)
PFAS compounds like PFOA and PFOS are detected in extremely low concentrations, measured in nanograms per liter or parts per trillion. This reflects one unit of PFAS per trillion units of water, demanding sensitive instruments and precise reporting.
Reporting levels use four decimal places for accuracy
The Floyd County system’s monitoring reveals PFOA detections around 0.0075 to 0.0136 µg/L (7.5 to 13.6 ng/L). Four decimal places ensure results distinguish small differences, but these are not health violation thresholds—just sensitive measurements.
The Hazard Index for Mixtures of Newer Fluorinated Compounds, Explained Without a Health Claim
Multiple PFAS compounds present with varying detection rates
Besides PFOA and PFOS, other per- and polyfluoroalkyl substances like PFBS, PFHxA, and PFPeA have been detected in Floyd County’s water. No current EPA health-based violation exists for these compounds in the system record.
Hazard indices assess combined exposure potential, not individual safety
Hazard index calculations combine the effects of several PFAS but do not establish safety or violation status. They aid researchers and regulators in understanding potential mixture impacts, not household risk.
How Sample Depth, Well Depth or Source Type Changes What a Reader Should Expect
Surface water is the Floyd County system’s supply
Since the area’s public water uses surface water sources, PFAS levels may differ from groundwater or well water. Variations may arise because surface water can receive runoff with PFAS from various origins.
Individual household wells may have distinct profiles
Private well owners in Floyd County should test their water independently, as local geology and depth affect chemical presence differently than in the municipal source.
How Seasonal or Multi-Year Variation Shows in the Record (Dates and Ranges Given)
Monitoring from April 2025 to March 2026 shows variable detections
Over 18 samples, PFOA and PFOS detections fluctuated, with the highest measured values at 0.0136 µg/L and 0.0092 µg/L, respectively. Such variation reflects changes in source water and environmental factors over time.
Other PFAS compounds also demonstrate intermittent detection
Compounds like PFBS show detectability in most samples with a wide range, indicating that PFAS presence is dynamic, not constant.
Why a Granular Carbon Bed and an Ion-Exchange Resin Are Documented Differently for PFAS
Granular activated carbon (GAC) adsorbs many PFAS molecules
This technology traps PFAS onto carbon particles, reducing concentrations of certain compounds, especially longer-chain molecules like PFOA and PFOS.
Ion-exchange resins target charged PFAS compounds differently
These resins attract PFAS based on electrical charge, effective for shorter-chain substances less removed by carbon. The Pentair PFAS Forever Chemicals Filter employs both mechanisms in a documented system.
How the Treated Water Differs at the Tap Once the Documented Technology Is in Place
Significant reduction of detected PFAS across multiple compounds
Using the Pentair PFAS Forever Chemicals Filter, residents can expect meaningful decreases in the range of PFAS detected in their water, including PFOA and PFOS, enhancing water quality at the tap.
Does not alter water’s baseline safety as established by public records
The technology improves PFAS presence but does not imply prior water was unsafe; improvements focus on lowering detected 'forever chemicals' per individual preference and concern.
This checklist clarifies how regional data informs, but does not define, household PFAS conditions in Floyd County. Knowing measurement units, compound mixtures, source types, and temporal changes aids in choosing treatment. The Pentair PFAS Forever Chemicals Filter provides a documented method to reduce PFAS levels at home, helping you decide which treatment class fits your needs.
