Many Nassau County residents wonder, "Is radon present in my water and should I be concerned?" Government data from aquifer 211MAGT indicates radon occurs in area wells, but determining its presence in your home requires specific water testing.

If you want to interpret the median and range of radon found in your area's water

The U.S. Geological Survey collected groundwater samples from nine wells in Nassau County's 211MAGT aquifer between 2012 and 2016. These wells, ranging in depth from 227 to 701 feet, showed radon-222 detected in all samples. The median value recorded was 91.0 picocuries per liter (pCi/L), with results spanning from 55.0 to 147.0 pCi/L. This means that half of the sampled results fall below 91.0 pCi/L and half above, illustrating natural variations in radon concentration across the aquifer.

If you want to understand how radon reduction equipment works with household water

The Pentair Radon in Water Filter uses specialized filtration technology designed to reduce radon concentration before water use. This system treats water directly by removing dissolved radon, helping reduce the exposure from household water use. It ships ready to configure for point-of-entry treatment, integrating into home water systems without requiring additional professionals.

If you want to know what the radon range means relative to federal standards and what it does not mean

None of the samples from Nassau County’s 211MAGT aquifer exceeded federal health-based thresholds for radon in water. A detected presence does not imply any violation or unsafe condition. The values reflect naturally occurring radon levels in groundwater and do not establish specific conditions for any individual household’s well without testing that household’s water directly.

If you want to consider how your home’s plumbing materials and age might influence radon-related water quality

Plumbing components and the age of your home's water system can affect water quality independently of source water radon levels. Materials such as older pipes or fixtures do not generate radon but can influence water flow and potential exposure pathways. Assessing plumbing separately from water source testing ensures a clearer understanding of radon presence and movement.

If you want to evaluate if a radon water treatment system can handle your household’s daily water needs

When choosing radon treatment, it is important to match the system’s capacity to your household’s typical water demand. Calculating daily water usage—considering factors like number of residents, appliances, and peak usage times—helps ensure the Pentair Radon in Water Filter functions effectively without limiting water availability.

If you want to know what long-term effects might occur if radon in water goes untreated

Radon primarily poses a risk if it escapes from water into indoor air during household use, potentially increasing radon exposure via inhalation. Leaving radon untreated in water over years can contribute incrementally to indoor radon levels but is one of several factors influencing overall exposure. Testing both water and indoor air remains the best approach to managing radon risk comprehensively.

For Nassau County households measuring water demand and seeking to reduce radon exposure from well water, the Pentair Radon in Water Filter delivers a documented, ready-to-configure solution designed to meet typical residential needs.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2016-10-05. 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 Radon-222 in the 211MAGT aquifer (Nassau County): 9 results from 9 wells, median 91.0 pCi/L, range 55.0-147.0 pCi/L; none above any federal threshold
