Public-System Sampling vs. Private Well Testing

Area-wide data reflect multiple wells, not individual household water

The U.S. Geological Survey collected 41 groundwater samples across 20 wells in aquifer 112DFSF within FIPS 110, CT. These represent area conditions but do not indicate a single well’s water quality or specific metallic taste level at your tap. To understand your household water, individual testing is necessary.

Samples do not establish personal water composition

These results demonstrate what has been detected in the region’s aquifer, providing context about potential contributors to metallic taste but not a direct measurement of your water.

Seasonal and Multi-year Variation Evidence

Sampling spanned six years, showing fluctuating iron levels

Samples taken between September 2011 and September 2017 reveal changes in iron concentrations over time. This suggests metallic taste contributors may vary seasonally or across years, emphasizing the importance of current and periodic testing for precise assessment.

Detection across dates shows natural variability

Iron was detected in 31 of the 41 samples, with some below detection limits, highlighting variability that could influence the intensity of metallic taste in household water.

Influence of Well and Sample Depth on Taste Factors

Sample depths ranged from 10 to 155 feet

Differences in sampling depth affect detected iron concentrations. Deeper wells may yield different water quality profiles than shallow wells, impacting metallic taste presence and severity in household water sources.

Well depth and aquifer zones relate to water chemistry

The aquifer’s layered structure means water drawn from various levels can have distinct levels of constituents linked to metallic taste, which area sampling helps to contextualize but does not precisely predict for any single home.

Long-Term Effects of Untreated Metallic Taste

Persistent metallic taste may reduce water appeal for drinking and cooking

While not a health hazard by itself, ongoing metallic taste can negatively affect user experience and water use patterns within a household.

Possible staining or discoloration over time

Water with elevated iron levels above secondary aesthetic thresholds has potential to cause staining of fixtures or laundry, although these outcomes depend on specific concentrations and household water use.

Understanding the Meaning of Measured Iron Ranges

Median iron concentration in samples is 2.56 mg/L with a wide range

Samples ranged from 0 to 4400 mg/L iron concentration, reflecting diverse natural conditions but not implying any safety concerns. Five results exceeded a secondary aesthetic standard of 0.3 mg/L, a taste and staining threshold without health implications.

Detection above aesthetic thresholds indicates possible taste impact, not danger

Values above aesthetic limits mean taste or appearance may be affected but do not indicate violations or unsafe water conditions by federal standards.

Summary

This page reviewed area groundwater iron data relevant to metallic taste concerns in household water in FIPS 110, Connecticut. It emphasized differences between public area records and individual well testing, variability over time and depth, and the meaning of aesthetic thresholds. For managing metallic taste, the Autotrol Metallic-Tasting Water Filter ships ready to configure and can help address taste-related water quality issues once your specific conditions are known.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2017-09-05. 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 Iron in the 112DFSF aquifer (FIPS 110): 41 results from 20 wells, median 2.56 mg/L, range 0.0-4400.0 mg/L; 5 above an AESTHETIC secondary standard only (secondary standard 0.3 mg/L (aesthetic)) - not a health finding
