Are nitrate levels a concern for your household water in Logan County? Government sampling of the local aquifer (327KNWH) shows varied nitrate concentrations, which means understanding this data can help you pick the right water treatment approach.
If you want to know how treated water differs after using a Pentair System
When nitrate is reduced with a Pentair Nitrate & Nitrite (Well) Filter, water at your tap shows lower nitrate concentrations, improving its suitability for household use, especially where levels might approach health advisory thresholds. The system targets nitrate specifically, helping to address concerns that arise from elevated nitrate without changing other water qualities.
If nitrate remains untreated in your household water over time
Continued consumption of water with elevated nitrate, particularly at or above federal limits, can pose health concerns, especially for infants and pregnant women. Over years, untreated nitrate does not dissipate naturally and can accumulate if the source water consistently has higher levels. Treatment helps reduce this risk by lowering nitrate before use.
If you want to understand what terms like 'detected,' 'median,' and 'range' mean in Logan County's sampling results
In the Logan County aquifer data, 'detected' means nitrate was measured above the reporting threshold in about 10 out of 14 samples. The 'median' (0.538 mg/L) represents the middle value of all measured nitrate levels, showing typical concentration, while the 'range' (0.043 to 12.6 mg/L) shows the spread between the lowest and highest nitrate measurements recorded. Notably, one sample exceeded the federal Maximum Contaminant Level (MCL) of 10.0 mg/L, indicating occasional elevated nitrate in the area but not necessarily in every well.
If you consider how the number of samples and wells affects your interpretation of Logan County nitrate data
The figures come from 14 samples taken from 7 different wells over nearly a year, providing an overview but not a comprehensive picture of all wells in the area. A smaller sample size means data reflects conditions in sampled locations but cannot guarantee the same for your specific well or depth. Testing your own water remains essential to know your home's nitrate status precisely.
If you want to know how sample and well depth affects expected nitrate levels in Logan County aquifer 327KNWH
Samples were taken from wells ranging 10 to 250 feet deep, showing that nitrate presence can vary with depth and well position. Shallow wells sometimes show higher nitrate due to surface influences, while deeper wells might differ. This variability underlines the importance of site-specific testing since local conditions influence nitrate concentration.
What you should NOT conclude: The Logan County aquifer data alone cannot specify nitrate levels at your home. Detecting nitrate in area wells does not mean your well exceeds health guidelines. The only way to confirm your household water’s nitrate level is through direct testing. The Pentair Nitrate & Nitrite (Well) Filter ships ready to configure for treating nitrate if and when your water requires it.

On record: U.S. Geological Survey sampling of Nitrate in the 327KNWH aquifer (Logan County): 14 results from 7 wells, median 0.538 mg/L, range 0.043-12.6 mg/L; 1 above a health-based federal MCL (federal MCL 10.0 mg/L)
