Starting with Aquifer 120UFAQ and Local Drinking Water Sources
The groundwater in Highlands County is primarily drawn from the 120UFAQ aquifer, a deep and extensive water-bearing formation providing well water to many homes. Water is typically pumped from wells that reach depths between 1500 and 1550 feet to reach this aquifer. From these wells, water travels through pipes to reach household taps.
Information to Record Before Seeking Treatment Advice
Before considering any water treatment, homeowners should gather important details about their water system. This includes the depth of their well, the date and results of any recent water testing, and any history of water quality issues. Also, note the source type (private or public supply) and any changes in water taste, odor, or appearance.
Maintenance Expectations of the C-Series Arsenic Filter
The C-Series Arsenic Filter ships ready to configure and is designed to reduce arsenic in residential water. Routine upkeep involves periodic filter replacement according to usage and water quality but requires no specialized tools or ongoing professional service. Maintaining filter effectiveness depends on following the provided schedule for monitoring and changing components.
How Arsenic Differs from Similar Water Contaminants
Arsenic is a naturally occurring element often found in groundwater, distinct from other common concerns such as iron or manganese. Unlike aesthetic minerals that may cause staining or taste issues, arsenic relates specifically to long-term health considerations. It is important not to confuse arsenic with substances regulated primarily for taste or appearance.
Understanding 'Detected', 'Median', and 'Range' in Local Sampling Data
Government sampling of groundwater in Highlands County's aquifer 120UFAQ found arsenic present in all tested wells, with median levels at 0.27 micrograms per liter and a range between 0.22 and 0.28 micrograms per liter. ‘Detected’ means the arsenic was measurable; it is not a signal that water is unsafe. The ‘median’ represents the middle concentration among samples, while the ‘range’ shows highest and lowest measured values. No measurements in this area exceeded federal arsenic thresholds.
Impact of Plumbing Material and Age on Water Quality
While source water arsenic concentrations come from the aquifer, plumbing materials and their age can influence the final water quality reaching taps. Some pipe materials may interact with water to leach metals or affect taste without changing arsenic levels. Regular inspection of household plumbing can help identify issues unrelated to source water arsenic.
Public System Records Versus Private Well Testing
Records from municipal systems and government sampling provide broad-area data on water quality, but private wells can differ significantly. The government figures shown come from a small number of deep wells sampled as part of a large-area effort, not from individual household testing. Testing a private well is necessary to understand its specific water conditions.
What This Data Does Not Establish About Your Water
The presence of arsenic in sampled wells within the Highlands County aquifer does not predict the concentration in any one household's water. Detection in government samples is not a violation or indication of unsafe water. Homeowners seeking treatment options should rely on their well's test results, and consider technologies like the C-Series Arsenic Filter as one way to help manage arsenic if present.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2026-01-26. These figures describe groundwater sampled in this area. They are not a test of any individual private well - only a test of that well can establish its own water.
On record: U.S. Geological Survey sampling of Arsenic in the 120UFAQ aquifer (Highlands County): 3 results from 2 wells, median 0.27 ug/L, range 0.22-0.28 ug/L; none above any federal threshold
