Understanding the Local Aquifer and Water Flow to Your Tap

The water serving many Suffolk County homes comes from aquifer 112GLCLU. Groundwater moves through layers of soil and rock before reaching household wells and taps, carrying with it substances including nitrate. These substances originate from sources in the surrounding environment and land use.

1. What You Should Note Before Seeking Treatment Advice

Record your well depth and water source details

Knowing the depth of your well and whether your water is drawn directly from the aquifer or mixed with other sources helps place nitrate levels in context.

Collect any previous water quality test results

Having certified laboratory reports on hand that include nitrate concentrations is essential for personalized advice.

Note household water use patterns

Estimating daily water consumption guides matching treatment system capacity to your needs.

2. Plumbing Materials and Age Have an Independent Effect

Older plumbing may influence nitrate readings

While nitrate primarily originates from source water, corrosion or leaching in aging pipes can slightly affect measurements or water chemistry.

Material types can alter water interaction

Different pipe materials interact with water differently, which does not change nitrate amounts but can impact other water characteristics important for treatment planning.

3. Sample Size and Range Behind Published Area Nitrate Figures

378 samples from 99 wells reveal variability

The U.S. Geological Survey sampled 99 wells in Suffolk County's 112GLCLU aquifer between 2011 and 2024 with 378 nitrate results documented.

Nitrate detected in 302 of 378 samples

Most samples showed measurable nitrate, though levels varied widely from as low as 0.037 mg/L to as high as 111.0 mg/L.

96 samples exceeded the federal maximum contaminant level

Among these results, 96 measured nitrate concentrations above the health-based federal MCL of 10.0 mg/L.

Sample depths ranged from 4 to 130 feet

Variation in sample depths reflects diverse well constructions and aquifer conditions affecting nitrate measurements.

4. Matching Treatment Capacity to Household Water Demand

Assess daily water volume needs

Estimate how much water your household uses daily to ensure any nitrate treatment system can handle the flow and concentration effectively.

Understand treatment system throughput

The Autotrol Nitrate & Nitrite (Well) Filter ships ready to configure for home use, designed to reduce nitrate concentrations safely when sized properly.

Plan for peak usage periods

Consider varying water use times to avoid overloading treatment capacity at peak demand.

5. Interpreting 'Detected,' 'Median,' and 'Range' in Area Sampling Data

'Detected' means nitrate was measured, not necessarily a problem

Detection indicates instruments found nitrate presence; it is not a violation or guarantee of unsafe water.

The median nitrate value is 5.06 mg/L across samples

This midpoint value shows half of the nitrate measurements were below and half above 5.06 mg/L in the sampled wells.

The range extends from 0.037 to 111.0 mg/L

This wide range reflects significant local variability in nitrate levels among wells in the Suffolk County aquifer.

Final Step: What Test Will Clarify Your Water’s Nitrate Level?

Ordering a certified laboratory test of your own household water specifically for nitrate concentration is the definitive way to assess your situation. A result above the federal MCL should prompt consideration of a targeted treatment solution like the Autotrol Nitrate & Nitrite (Well) Filter, which is designed for direct purchase and ships ready to configure for residential use.

Understanding your actual water nitrate concentration and daily water use will guide selecting and sizing effective treatment, ensuring safe water for your household.

Source: USGS groundwater sampling. Sampled 2024-05-23. 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 Nitrate in the 112GLCLU aquifer (Suffolk County): 378 results from 99 wells, median 5.06 mg/L, range 0.037-111.0 mg/L; 96 above a health-based federal MCL (federal MCL 10.0 mg/L)
