1. How Sample Depth, Well Depth, or Source Type Affects Expected Manganese Levels

The U.S. Geological Survey has collected manganese data from 22 samples across 17 wells in Nassau County’s aquifer 211LLYD. These wells range in depth from 209 to 1478 feet, representing different groundwater conditions. Generally, manganese concentration can vary with depth due to geochemical changes within the aquifer. Deeper wells may show different manganese levels than shallower ones. It’s important to know that these samples reflect the aquifer’s characteristics broadly but do not specify the manganese level in any one household’s water.

2. Additional Questions Commercial or Industrial Operators Ask Compared to Household Users

While residential users focus on manganese’s effects on water appearance and appliance staining, commercial or industrial operations may have stricter concerns about manganese’s impact on manufacturing processes or equipment longevity. They often require detailed testing of their own supply to adjust treatment levels appropriately. Households typically prioritize managing visible staining or taste issues linked to manganese presence, which can fluctuate seasonally or over time.

3. Understanding 'Detected', 'Median', and 'Range' in This Sampling Record

Out of the 22 samples taken, manganese was detected in 18 results, with four below the reporting limit. The median manganese concentration is 111.5 micrograms per liter (µg/L), meaning half the detected values are below this level and half above. The full range spans from 0.19 µg/L up to 3180 µg/L. Detection simply means the measurement instrument found manganese; it is not a regulatory violation or safety concern. None of the samples exceeded federal manganese thresholds.

4. Sample Size and Its Impact on Data Interpretation

The data comes from 17 wells sampled over more than a decade, which provides a good regional overview of manganese in Nassau County’s aquifer 211LLYD. However, this number of samples is still modest and represents broad area conditions rather than detailed local variations. Individual household wells may have different manganese levels. For precise information about a home’s water, separate laboratory testing of that water is necessary.

5. Reading Nassau County Manganese Data as a Household Owner

When reviewing the median and range, a homeowner should understand that manganese in their water could be as low as near zero or as high as thousands of micrograms per liter, depending on their source and conditions. The median value shows a moderate presence typical for the area’s aquifer. If existing equipment struggles to keep up, it may be due to manganese fluctuations or the volume treated. Testing specific household water identifies exact manganese concentrations for tailored management.

6. Changes You Can Expect After Using the Fleck Black Manganese Stains Filter

The Fleck Black Manganese Stains Filter ships ready to configure and is designed to reduce manganese’s staining and discoloration effects on household water. When operating as intended, it helps maintain clearer water, reducing visible deposits on fixtures, laundry, and dishes. While it does not alter the manganese concentration reported in regional sampling, it can improve water aesthetics and protect appliances as manganese levels vary or increase beyond the filter’s capacity.

This information comes from the documented sampling of 17 wells in Nassau County’s 211LLYD aquifer as collected by the U.S. Geological Survey over 2010 to 2024. For the full official record and data access, visit the U.S. Geological Survey water data site for location 405244073350901.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2024-03-27. 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.
