This week, many households in Rockingham County face a key decision: which class of water treatment is suitable for their well water concerning nitrate levels? Understanding regional water quality data helps clarify what treatment is needed, if any, before selecting equipment.

Belief: The Pentair Nitrate & Nitrite Filter instantly removes all nitrates and nitrites from my well water.

The Pentair Nitrate & Nitrite Filter is designed to reduce nitrate and nitrite concentrations through specialized filtration technology tailored for well water. It operates by targeting these specific contaminants, thereby improving water quality where elevated levels may be present. This system ships ready to configure, enabling households to directly address their treatment needs for nitrates and nitrites without delay.

Belief: The system needs constant service or complicated upkeep to function properly.

Maintenance of the Pentair system follows a straightforward rhythm based on the usage and measured water quality. Routine monitoring and periodic replacement of filter components ensure continued effectiveness, but daily or intensive intervention is unnecessary. Households can plan maintenance intervals according to their usage patterns and water test results.

Belief: Commercial and industrial water concerns about nitrates are the same as for residential wells.

Commercial or industrial water users often face different regulatory standards and water volume demands. They might require more frequent testing, higher capacity treatment options, and customized system adjustments. Residential users typically deal with smaller volumes and simpler regulatory frameworks, which simplifies their decision-making and maintenance compared to larger operations.

Belief: Nitrate levels in Rockingham County's bedrock aquifer fluctuate wildly year to year and seasonally.

According to U.S. Geological Survey groundwater sampling between 2011 and 2019 across six separate wells 150 to 500 feet deep in Rockingham County’s bedrock aquifer, nitrate (specifically nitrite) concentrations ranged from 0.001 to 0.042 mg/L with a median of 0.006 mg/L. Of 84 results, 32 detected nitrite, while 52 were below reporting limits. These results show variability but within a relatively low and stable range over multiple years and seasons.

Belief: Nitrate concentrations in Rockingham County’s bedrock aquifer are worse than in neighboring counties.

Comparing this area’s nitrite record to neighboring regions requires care because geological conditions, sampling depth, and land use differ. Rockingham County’s bedrock aquifer results do not indicate elevated or hazardous nitrate levels relative to the federal reference, and neighboring counties may have similar or higher variability depending on local factors. This highlights the value of localized testing rather than generalizing from nearby records.

What you should not conclude from this area's nitrate data: The sampling results represent measurements from a small set of deep wells in Rockingham County’s bedrock aquifer and cannot confirm the nitrate concentration in your personal well. Detection is not a violation or proof of unsafe water, and all results were below established federal nitrate thresholds. The only way to determine your water's nitrate level is through specific testing of your well. Consider using the Pentair Nitrate & Nitrite Filter as a documented treatment option if testing reveals elevated nitrate or nitrite in your household water.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2019-05-15. 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 Nitrite in the BEDROCK aquifer (Rockingham County): 84 results from 6 wells, median 0.006 mg/L, range 0.001-0.042 mg/L; none above any federal threshold
