The groundwater in Licking County, Ohio, primarily comes from the local aquifer, a natural underground layer holding water that feeds private wells and municipal supplies. Water travels through soil and rock before reaching household taps, picking up trace minerals and elements along the way. Among these elements, arsenic occasionally appears and can require attention based on concentration and individual water use.
Myth: A Few Wells Sampled Mean Clear, Local Arsenic Levels Everywhere
The U.S. Geological Survey sampled 9 wells within the Licking County aquifer, collecting 29 arsenic measurements between November 2012 and April 2013. While this provides a snapshot of conditions, 9 wells represent a small portion of all groundwater sources in the area. Conditions can vary widely between wells due to geology and depth. This means the regional arsenic figures offer context, not precise predictions for every household.
Myth: Median Arsenic Level Defines What Is in My Well
The median arsenic concentration from the regional samples was 25.6 micrograms per liter (µg/L), with individual results ranging from 5.7 to 67.5 µg/L. As a homeowner, your well's arsenic concentration could be below, near, or above this range. The median serves as a midpoint indicator for these sampled wells, not a guaranteed measure of your own water quality. Testing your own water remains the way to understand your actual conditions.
Myth: If Arsenic Is Detected Regionally, Treatment Must Match the Highest Recorded Levels
When selecting treatment, consider your household’s daily water usage alongside potential arsenic concentrations. Treatment systems like the Fleck Arsenic Filter ship ready to configure and are designed to address arsenic levels within and beyond the regional range. Proper configuration depends on understanding your daily volume needs and confirming your individual arsenic level through certified laboratory testing.
Myth: All Wells Draw from the Same Depth and Have Similar Arsenic Levels
Sample depth and well construction significantly affect arsenic presence. The USGS samples covered multiple wells with varying depths, yet individual well depth can strongly influence arsenic concentration. Deeper wells may access water with different arsenic characteristics than shallow ones. Source type and local geology also contribute to variability, so regional data provide guidance but cannot substitute for well-specific results.
Myth: All Household Water Fixtures Are Equally Affected by Arsenic
Arsenic primarily affects water quality at the point it enters the home. Fixtures that use water directly from the source, such as kitchen taps and drinking water outlets, are the highest priority for treatment. Appliances like water heaters or irrigation systems may be less impacted, depending on household setup. Understanding where arsenic enters your daily water use helps focus treatment efforts where they matter most.
Myth: Public Water System Records on Arsenic Can Replace Private Well Testing
Public water systems in Licking County maintain records demonstrating compliance with federal arsenic standards. The USGS regional data similarly found no arsenic results above federal thresholds in sampled wells. However, public system records reflect treated and monitored water, not raw private well water. Private wells require individual testing to establish arsenic levels and guide treatment decisions.
Conclusion: What Area Data Can and Cannot Tell You About Your Water
Regional arsenic measurements from the Licking County aquifer provide valuable insight into possible water conditions but do not identify your well’s unique level. Detection in all sampled wells confirms arsenic is present in the environment, yet none exceeded federal safety thresholds, indicating no health-based violations in those samples. To address your household’s water quality with confidence, laboratory testing specific to your well is essential.
The Fleck Arsenic Filter offers a direct purchase option that ships ready to configure, providing a documented method to reduce arsenic levels if testing confirms its presence at concerning concentrations. Using area data as part of your assessment supports informed choices but should be paired with personal water analysis for tailored and effective treatment.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2013-04-23. 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.
