Government sampling in St. Charles County's aquifer 110QRNR shows arsenic was detected in all samples but none exceeded federal health thresholds.

How Plumbing Material and Age Affect Arsenic Exposure

Older pipes do not increase arsenic levels from groundwater

Arsenic originates in the groundwater, not from plumbing materials, so pipe age or type does not raise arsenic content.

Corrosion-related metals differ from arsenic concerns

While plumbing can add metals like lead or copper, arsenic presence relates to the source water, not pipe corrosion.

Information to Record Before Seeking Treatment Advice

Test your own water for exact arsenic concentration

Because government data reflects area sampling, only a laboratory test of your well or tap water can reveal your precise arsenic level.

Note your water source characteristics

Record your well depth and type, since sampled wells ranged from 8 to 43 feet deep, which can influence water quality.

List any treatment equipment currently used

Knowing if you use filtration or other systems helps in evaluating arsenic treatment needs.

Understanding the Sampling Record Terms

Detected means arsenic was measurable in all samples

Every sample found some arsenic, from 0.26 to 18.5 micrograms per liter (µg/L), showing presence but not a violation.

Median shows typical arsenic levels in the area

The median concentration of 0.53 µg/L indicates that half the samples had arsenic below this level and half above.

Range indicates variability across wells

Levels varied from 0.26 to 18.5 µg/L, reflecting natural differences between sites but all below federal thresholds for safety.

Additional Concerns for Commercial or Industrial Operators

Higher water volumes may require larger treatment capacities

Commercial users should consider treatment systems sized for greater flow to maintain effective arsenic reduction.

Regulations may differ for non-residential uses

Operators should review applicable regulatory requirements beyond household standards for arsenic.

Process water quality impact varies by industry

Industries reliant on water purity may require specialized arsenic filtration to protect product quality and equipment.

Fixtures, Appliances, and Processes Most Affected by Arsenic

Drinking and cooking faucets are priority points

Arsenic exposure primarily concerns water consumed or used in food preparation.

Water-using appliances can accumulate deposits

Devices like ice makers and coffee machines may be affected by arsenic deposits over time, impacting function.

Bathing fixtures less impacted by arsenic health concerns

While arsenic exposure through skin contact is minimal, ingested water is the main concern.

Changes After Arsenic Treatment with the C-Series System

Treated water shows reduced arsenic levels at the tap

The C-Series Arsenic Filter is designed to remove arsenic effectively, providing safer water for consumption.

Water taste and clarity remain stable or improve

The filtration process does not produce adverse taste changes; it primarily targets arsenic removal.

Regular monitoring is advised to ensure continued performance

Periodic testing confirms the filtration system maintains arsenic reduction over time.

To resolve uncertainty about your household water, order a laboratory test measuring arsenic concentration specifically in your water source. A result below federal health thresholds typically means arsenic removal treatment can be tailored appropriately, with the documented C-Series Arsenic Filter as a proven option to reduce arsenic at the tap.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2015-08-12. 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 110QRNR aquifer (St. Charles County): 13 results from 11 wells, median 0.53 ug/L, range 0.26-18.5 ug/L; none above any federal threshold
