The Suffolk city County aquifer, specifically aquifer 217PTMC, supplies water through a network of deep wells ranging from 500 to 1775 feet. This is a typical arrangement for public and private water access in the area, with water traveling from these underground sources to household taps. Radon-222, a naturally occurring radioactive gas, is a constituent measured in this aquifer to assess potential presence in drinking water.
If you are reviewing the USGS radon sample median and range data
Seventeen radon results from three wells collected between 2019 and 2025 show levels consistently detected, with a median of 200.0 pCi/L and a range between 160.0 to 350.0 pCi/L. These measurements are area-wide and do not specify your own household water. All values came below any federal threshold, indicating regulatory compliance at the sampled wells. The median reflects the middle value of the data collected, meaning half of samples were below and half above this concentration within this specific aquifer segment.
If you are comparing public system radon records to your well water testing
Government samples provide a snapshot of regional aquifer conditions but cannot confirm your well's radon level. Private well testing by a certified lab is essential to identify your household-specific radon concentration. Public system data offer context but do not replace individual water analysis due to local variations in geology and well depth.
If you are considering how radon treatment technology addresses this constituent
Radon in water can be reduced by specialized filter systems designed to remove radioactive gas. The Pentair Radon in Water Filter uses filtration media formulated to capture radon effectively before water reaches home use points. This approach lowers radon levels in household water, potentially reducing exposure via inhalation or ingestion.
If you are evaluating maintenance needs of radon water filters
The Pentair system ships ready to configure with straightforward upkeep requirements. Routine maintenance involves periodic replacement of the filtration medium according to water usage and system condition. Regular inspection ensures continued radon reduction performance without complex technical support.
If you are preparing for treatment discussions
- Note results from your own well water radon test, including concentration and testing date.
- Document water source details such as well depth and aquifer name.
- Record any water quality observations like odor or taste changes.
- Understand recent local government radon sampling results for background context.
Understanding radon levels in Suffolk city aquifer 217PTMC requires combining area data with private testing. For residents seeking water radon reduction, the Pentair Radon in Water Filter offers a ready-to-configure system that addresses this specific constituent based on measured demand and local water conditions.

On record: U.S. Geological Survey sampling of Radon-222 in the 217PTMC aquifer (Suffolk city County): 17 results from 3 wells, median 200.0 pCi/L, range 160.0-350.0 pCi/L; none above any federal threshold
