How many samples and wells stand behind the reported nitrate levels, and what does a small sample mean?

Government data from the U.S. Geological Survey includes 14 nitrate measurements taken from three wells in Sharkey County’s aquifer 112MRVA. These results span from August 2010 to June 2011 and come from wells ranging 3 to 24 feet deep. While this sampling gives insight into area groundwater, the relatively small number of wells and samples means it captures only a snapshot of local nitrate conditions, not the full variability or your specific well’s status.

How do public-system records differ from private-well testing in what they establish about nitrate?

The USGS data reflects direct testing of groundwater from wells in the county, not finished municipal water systems. Public water system records typically monitor treated water delivered to consumers and follow regulatory reporting requirements. By contrast, these well samples show nitrate concentrations as they appear at the source, before any treatment. For a household relying on a private well, testing your own water is essential because local conditions and well construction can cause nitrate levels to vary substantially from these regional figures.

How does nitrate enter groundwater or the distribution system in Sharkey County?

Nitrate in groundwater often comes from agricultural fertilizers, livestock operations, septic systems, and natural soil processes. Sharkey County’s rural and agricultural landscape makes these potential sources relevant. Nitrate moves through soil and rock layers into aquifers like 112MRVA, where it can persist and accumulate depending on rainfall, soil type, and land management. Unlike surface water, groundwater nitrate presence usually reflects long-term land use patterns rather than transient contamination events.

How do sample depth, well depth, or source type change what a homeowner should expect about nitrate?

Sampling in Sharkey County occurred at shallow well depths from 3 to 24 feet. Nitrate concentrations often decrease with well depth because deeper groundwater interacts less with surface contaminants. Therefore, deeper wells might show lower nitrate levels compared to shallow ones. Groundwater wells tapping the 112MRVA aquifer may have variable nitrate depending on the screened interval and local geology. Household water quality can differ significantly from the USGS sample range, making specific testing the only way to know your own water’s nitrate concentration.

What household or facility symptoms suggest nitrate is present, and which do not?

Nitrate in water is colorless, odorless, and tasteless at typical concentrations, so households generally do not notice it without testing. Symptoms often attributed to nitrates, like a metallic taste or staining, are not reliable indicators. High nitrate exposure poses a health concern particularly affecting infants and pregnant women, linked to conditions like methemoglobinemia or “blue baby syndrome.” Because these effects are not detectable by household senses, water testing is the only dependable method to identify nitrate issues.

Tackling nitrate in Sharkey County water may involve choosing between treatment options that address measured levels. The Fleck Nitrate & Nitrite (Well) Filter addresses nitrate concentrations by selectively filtering these compounds from well water, delivering water ready for household use. It ships ready to configure, providing a direct solution for households that find elevated nitrate in their water tests and seek a practical approach to reduce nitrate exposure in the home.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2011-06-02. 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 112MRVA aquifer (Sharkey County): 14 results from 3 wells, median 0.2785 mg/L, range 0.022-13.1 mg/L; 1 above a health-based federal MCL (federal MCL 10.0 mg/L)
