A laboratory report for Radium-228 in Suffolk County's aquifer 211MAGT typically lists concentrations detected between -0.04 and 1.8 pCi/L, with a median of 0.475 pCi/L based on 28 samples taken from 25 wells between 200 to 900 feet deep over 2012-2022. None of these measurements in this area exceeded federal thresholds.
How Sample Depth or Source Type Affects Expected Uranium-Radium Levels
Deeper wells generally show varied Radium-228 concentrations within the county range
Government sampling covers wells 200 to 900 feet deep, showing a range of Radium-228 values but no exceedances. Wells in this depth range in Suffolk County can have Radium-228 detected across this range, meaning depth influences measured concentrations in this aquifer.
Shallow groundwater sources may differ from deep aquifer results
This data does not include shallow or surface water sources. Those may present different Uranium-Radium profiles and would need separate testing.
Maintenance Rhythm for the Pentair Uranium & Radium System
Regular replacement of treatment media based on capacity
The Pentair Uranium & Radium System is rated for a grain capacity of 32,000 grains, requiring periodic media replacement or regeneration to maintain effective contaminant removal and ensure household supply keeps up with demand.
Monitoring flow rates and system performance routinely
Maintaining consistent water quality relies on routine checks of flow and pressure, ensuring the system functions within designed parameters given the Uranium-Radium load presented by your source water.
Additional Questions for Commercial or Industrial Operators
Scaling up system size and capacity needs based on usage
Commercial users must consider higher volumes and continuous operation demands, necessitating systems with greater grain capacity or multiple units.
Compliance with occupational exposure and discharge regulations
Operators may need to track cumulative contaminant removal and document waste handling, beyond typical household concerns.
Differences Between Public-System Records and Private-Well Testing
Public records show area-wide sampling data, not individual well levels
The USGS data reflect regional groundwater trends from sampled wells in Suffolk County aquifer 211MAGT but do not define any single household’s water quality.
Private testing is necessary to establish specific household water Radium-228 concentration
To understand your home's Uranium-Radium levels precisely, a laboratory test on your water supply is required.
Sources of Uranium and Radium in Suffolk County Groundwater
Natural geologic presence in the aquifer's mineral content
Radium-228 arises as part of the natural radioactive decay chain of elements within Suffolk County's aquifer minerals, contributing to detected levels in groundwater.
Groundwater movement mobilizes these elements into well water
Water passing through uranium- and radium-bearing rock formations can carry dissolved Radium-228 into wells drawing from the 211MAGT aquifer.
Deciding how to address Uranium-Radium concentration begins with understanding local groundwater data and completing your own water testing. The Pentair Uranium & Radium System offers a documented solution designed to meet household demands when existing equipment falls short.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2022-08-11. 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 Radium-228 in the 211MAGT aquifer (Suffolk County): 28 results from 25 wells, median 0.475 pCi/L, range -0.04-1.8 pCi/L; none above any federal threshold
