How Sample and Well Depth Affect Expected Arsenic Levels

The groundwater samples from Chicot County’s aquifer 110ALVM were collected from wells 90 to 100 feet deep. Arsenic concentrations can vary depending on the depth and type of the water source. Generally, deeper wells may encounter different geologic layers that contribute to differing arsenic presence. The local USGS data reflects sampling of this specific depth range, so well owners with significantly shallower or deeper wells might observe different arsenic levels and should consider testing their own water for accurate assessment.

Comparing Arsenic Records Between Chicot County and Neighboring Areas Without Overinterpretation

When looking at arsenic data from nearby counties or aquifers, it’s important to avoid assuming the same conditions apply to your well. Regional variations in geology and groundwater flow influence arsenic concentrations. For example, the median arsenic levels measured in Chicot County wells cannot be simply equated to neighboring counties’ values without accounting for differences in aquifer characteristics and sampling methods. Such comparisons are best used as context rather than a definitive prediction of your water’s arsenic content.

Interpreting the Median and Range of Arsenic in Chicot County as a Homeowner

The USGS groundwater sampling in Chicot County (aquifer 110ALVM) between 2016 and 2023 showed three arsenic results ranging from 0.26 to 0.34 micrograms per liter (ug/L), with a median of 0.33 ug/L. All detections were below the reporting limit and federal thresholds for arsenic. This means arsenic was present but at very low levels in these samples, not indicating a violation or immediate health concern. Homeowners should test their own well water, as actual levels may vary.

How the C-Series Arsenic Filter Removes Arsenic from Your Water

For homeowners confirming elevated arsenic in their water, the C-Series Arsenic Filter provides a reliable solution. This system uses specialized filtration media designed to reduce arsenic concentrations efficiently. It ships ready to configure for residential setups, helping to mitigate the presence of arsenic detected in water. Using this technology supports maintaining water quality within recommended safety margins established by regulatory standards.

What the Measured Arsenic Range Means Versus Federal Standards—and What It Does Not Imply

The arsenic concentrations detected in Chicot County’s sampled wells are well below the U.S. Environmental Protection Agency’s maximum contaminant level (MCL) for arsenic, which is 10 micrograms per liter. The low range measured does not represent a violation or unsafe condition but indicates naturally occurring trace amounts. It also does not guarantee your well water has the same concentrations. Only a direct test of your household water can confirm your specific levels.

Seasonal and Multi-Year Variation in Arsenic Levels Observed in the USGS Record

The data spans from August 2016 to August 2023, showing stable arsenic readings with minimal variation across that time. This suggests the local arsenic presence in groundwater remains relatively constant in this aquifer at the sampled depths. Seasonal fluctuations, if present, were not substantial enough to shift the levels beyond the narrow range observed. Regular testing can help homeowners track any future changes over time.

What You Should Not Conclude from Area Arsenic Data

Although the area data provides valuable insight, it should not be used to assume your household well has similar arsenic levels without testing. The samples reflect only two wells at a certain depth range and cannot define all local variations. Detection of arsenic in the area data is not a violation, does not mean your water is unsafe, and does not dictate your treatment needs without your own water quality results. Testing your water is essential to choose the appropriate class of treatment.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2023-08-09. 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 110ALVM aquifer (Chicot County): 3 results from 2 wells, median 0.33 ug/L, range 0.26-0.34 ug/L; none above any federal threshold
