What is arsenic concentration in Fayette County aquifer 327PCNS water? Government groundwater sampling across three wells found arsenic consistently present but always below federal health-based limits. This means arsenic was detected in every sample, yet at levels considered safe according to those regulations.

If you read the median and range in this government record as a homeowner

The U.S. Geological Survey sampled groundwater in Fayette County's aquifer 327PCNS four times between 2011 and 2016. The median arsenic concentration was 0.075 micrograms per liter (µg/L), with all results ranging from 0.05 to 0.11 µg/L. For comparison, the federal maximum contaminant level (MCL) for arsenic in drinking water is 10 µg/L. These findings confirm that arsenic is consistently present at low levels that are far below the MCL in this aquifer.

If you consider seasonal or multi-year variation based on the sampling dates and ranges

Sampling was spread between August 2011 and September 2016. The narrow range of 0.05 to 0.11 µg/L over this five-year period suggests little variation in arsenic levels across seasons or years at these wells. While arsenic concentrations can fluctuate in groundwater due to environmental factors, these data indicate stable, low-level presence in Fayette County's aquifer 327PCNS within the sampled depth of 255 to 400 feet.

If you understand why aesthetic secondary standards differ from health-based limits for arsenic

Some regulatory thresholds address aesthetic water qualities like taste, staining, or corrosivity rather than health risks. However, for arsenic, the key reference is the federal health-based MCL. The detected arsenic amounts in Fayette County's aquifer are well below this limit, indicating no known health risk from the arsenic itself. This distinction is important to avoid confusing minor aesthetic or incidental detections with safety concerns.

If your household notices symptoms that might or might not point to arsenic presence

Typical household signs linked to arsenic are difficult to identify because arsenic does not cause taste or odor changes at low concentrations. Unlike issues such as hardness or iron staining, arsenic presence is not associated with visible or sensory water quality changes. Persistent symptoms like equipment wear or inefficiency are usually unrelated to arsenic and require specific water testing to confirm arsenic as a factor.

If you know what ‘detected’, ‘median’, and ‘range’ mean for the record on this page

• Detected: Arsenic was measured above the test's reporting limit in all samples, confirming its presence at trace levels.
• Median: The middle value of 0.075 µg/L represents a typical arsenic concentration found in these wells.
• Range: Values varied between 0.05 and 0.11 µg/L, showing minor fluctuations but no spikes beyond this band.

If you distinguish this arsenic issue from two commonly confused water problems

Arsenic presence is often mistaken for iron or manganese contamination, which cause visible staining and taste differences. Unlike these, arsenic does not alter water color or odor at the levels detected here and is invisible without laboratory analysis. Another confusion arises with aesthetic issues such as hardness that impact soap performance. Arsenic requires specific testing as it does not produce such effects.

In summary, the U.S. Geological Survey data for Fayette County aquifer 327PCNS show low-level arsenic presence consistently below federal limits. To confirm your household’s own water status, a laboratory arsenic test of your specific supply is necessary. For residences needing enhanced water quality beyond existing equipment capacity, the C-Series Arsenic Filter ships ready to configure and is designed to reduce arsenic effectively in residential systems.
