Arsenic Presence in Highlands County's Aquifer 120UFAQ Based on USGS Sampling

Government monitoring by the U.S. Geological Survey collected groundwater samples from two separate wells in Highlands County within the 120UFAQ aquifer. These wells were measured at depths ranging between 1520 and 1530 feet. Sampling extended from April 2015 through January 2026, producing three arsenic concentration results.

All detected arsenic results fell between 0.22 and 0.28 micrograms per liter (ug/L), with a median of 0.27 ug/L. Importantly, none of these results surpassed federal arsenic thresholds, indicating that within this sampled area and aquifer, arsenic levels have remained below regulatory concern. However, these figures represent area conditions and cannot define the arsenic concentration in any individual household water supply.

Understanding What Arsenic Means for Your Household Water

Arsenic is a naturally occurring element that can be present in groundwater, sometimes seeping into wells from underlying geology. In water, arsenic at elevated levels may pose health risks over long-term exposure. Because arsenic concentration can vary significantly even between neighboring properties, determining your household’s arsenic level requires specific testing of your actual water supply source.

Given that arsenic concentrations can fluctuate with well depth, aquifer characteristics, and local geology, relying solely on regional sampling data does not provide a definitive measure of your residential water quality. Testing your own water is necessary to assess if arsenic treatment is warranted.

Addressing Arsenic Treatment When Existing Equipment Has Failed

If your current water treatment system designed for arsenic removal has failed or ceased to function properly, it is important to consider replacement solutions that can effectively reduce arsenic presence once your testing confirms treatment need.

One documented technology designed specifically for arsenic reduction in residential water use is adsorptive media filtration. This method utilizes specialized media that attract and hold arsenic from water as it passes through, reducing arsenic levels before reaching household taps. The C-Series Arsenic Filter uses this adsorptive media technology to address arsenic in water supplies.

Features of Adsorptive Media Technology for Arsenic

  • Targets arsenic species effectively in groundwater.
  • Operates without chemicals by physically removing arsenic compounds.
  • Applicable to residential systems and ships ready to configure for integration with existing water routing.

What You Should Do Next

  • Obtain a certified water test specifically measuring arsenic concentration from your household water supply.
  • Review your testing results in relation to federal guidelines and consult water quality experts to determine treatment necessity.
  • Explore adsorptive media filtration equipment such as the C-Series Arsenic Filter, designed for residential use and shipped ready to configure.

Understanding regional data from Highlands County’s aquifer 120UFAQ provides context but not a household-specific answer. Testing your own water remains the crucial step to secure safe and effective treatment after your previous equipment fails. Adsorptive media filtration stands as a proven approach for reducing arsenic to meet residential water quality goals.
