Local Aquifer and Water Delivery in FIPS 180, CT
Groundwater drawn from aquifer 112DFSF in FIPS 180, CT, supplies many residential wells. Water travels from depths between 10 and 80 feet, sourced through various local wells into home tap systems. Understanding this aquifer's quality helps in addressing any metallic taste noticed at the tap.
Interpreting Certified Laboratory Tests for Metallic Taste Causes
What Test Reports Reveal About Iron Levels
Certified labs report iron presence in micrograms per liter (ug/L). In the regional sampling of 19 wells, iron was detected in some but not all samples, with a median value of 19.5 ug/L and a range from 0.04 to 700.0 ug/L. Detection does not indicate a health violation. Reading your own water test involves noting where your levels fall within these ranges.
How Fleck Metallic-Tasting Water Filter Addresses Metallic Taste
Reduction of Iron and Related Compounds
The Fleck Metallic-Tasting Water Filter uses a proven system designed to reduce dissolved metals contributing to metallic tastes. It ships ready to configure for home use, providing a practical approach to improving water taste where iron and similar metals contribute to undesirable flavors.
Entry of Metallic-Taste Components into Local Groundwater
Natural and Environmental Sources in the CT Aquifer 112DFSF
Iron naturally occurs in soils and rocks surrounding the aquifer. Its presence in groundwater results from natural leaching processes over time. Variations in iron levels reflect changes in geology and water table conditions rather than contamination events.
Understanding Median and Range in Regional Sampling as a Homeowner
Interpreting 19.5 ug/L Median and Up to 700.0 ug/L Range
The median value indicates that half the detected iron measurements were above 19.5 ug/L and half below, representing the typical range in the area. The wide range up to 700.0 ug/L shows variability among wells but does not imply all homes experience this level. Homeowners should compare their specific test results to these figures to understand their own water quality context.
Seasonal and Multi-Year Variations in Aquifer Iron Levels
Data Span from 2015 to 2025 Shows Fluctuations
Sampling over a decade reveals changes in iron detection and concentration levels, with some years showing more detections than others. Seasonal changes in groundwater flow and chemistry can influence measured iron levels, affecting metallic taste strength at different times.
Sample Size and Data Reliability for Area Aquifer 112DFSF
Seventy Results from Nineteen Wells Provide a Regional Overview
This dataset offers a broad picture of iron levels across local wells, though individual well conditions may differ. A small number of wells means local variability could exist outside the reported range.
Recommended Action: Testing Your Own Water
To determine the cause of metallic taste in your household, order a certified laboratory test for iron and related metals. A result indicating a concentration within or above the regional range can confirm if the metallic taste is linked to iron levels. With this information, the Fleck Metallic-Tasting Water Filter can be considered as a targeted solution.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2025-11-21. 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 180): 70 results from 19 wells, median 19.5 ug/L, range 0.04-700.0 ug/L; none above any federal threshold
