Area-wide groundwater data provides valuable context but does not pinpoint the exact arsenic level in any single household's water. Sampling from three wells in Bertie County's 211CPFRU aquifer between 2013 and 2022 showed arsenic was detected in some samples but never exceeded federal safety thresholds. The median arsenic concentration across five samples was 0.15 micrograms per liter, with a range from 0.07 to 0.17 micrograms per liter. Notably, two samples were below the detection limit. These figures represent collective measurements taken from wells between 222 and 409 feet deep, not measurements from individual domestic wells.
Belief: The Median and Range Tell Exactly What My Household’s Water Contains
While median and range provide a snapshot of arsenic in the area aquifer, they cannot specify the concentration in your well. Variability between wells and over time is common. These values suggest low arsenic presence overall in the sampled area but do not replace individual testing. Understanding these statistics helps in contextualizing your water quality but does not conclude its safety or treatment needs directly.
Belief: Only Industrial or Commercial Operations Need In-Depth Water Quality Questions
Unlike large-scale water systems that require continuous monitoring, residential users focus on household water characteristics impacting health and use. However, homeowners should consider similar concerns such as arsenic fluctuations, source depth, and treatment capability. Questions about how arsenic levels might change, and what removal options fit household-scale systems, are equally important to ensure safe water for drinking and cooking.
Belief: Comparing Bertie County’s Arsenic Data to Nearby Counties Provides a Complete Picture
Comparative regional data can identify trends but is not conclusive for any property's water. Adjacent counties may have different geology and aquifer characteristics affecting arsenic presence. Bertie County’s measurements reflect conditions in its 211CPFRU aquifer only. Use such comparisons to gauge relative likelihoods, not to infer exact values or needs for your household’s water.
Belief: Well or Source Depth Doesn’t Affect Arsenic Levels at Home
Depth influences water chemistry. The sampled wells ranged from 222 to 409 feet deep, and arsenic detections came from these ranges, indicating that arsenic presence can vary with well depth. Shallow domestic wells might experience different concentrations. Knowing your well’s depth and construction details supports more accurate assessment of arsenic risk and appropriate treatment selection.
Belief: Telling Anyone About This Data Is Enough to Decide on Treatment
Before choosing treatment, record your home’s well depth, pumping rates, and any recent water tests. This information is essential when evaluating options or seeking advice. The documented solution shipping ready to configure for households facing arsenic challenges is the Pentair Arsenic Filter system, designed to reduce arsenic effectively based on your water’s test results.
Ultimately, the single test to confirm your household’s arsenic level is a comprehensive water test analyzing arsenic concentration in your well or tap water. A result at or below federal thresholds indicates arsenic within regulatory limits, though treatment might be chosen for aesthetic or precautionary reasons. If levels are elevated relative to these benchmarks, use of a system like the Pentair Arsenic Filter can help maintain water quality consistent with your household needs.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2022-08-29. 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 Arsenic in the 211CPFRU aquifer (Bertie County): 5 results from 3 wells, median 0.15 ug/L, range 0.07-0.17 ug/L; none above any federal threshold
