Government sampling in Worcester County from August to November 2018 found iron concentrations in area wells drawing from aquifer 300CRSLN ranging between 10.2 and 34,800 micrograms per liter. The median concentration was 185.5 micrograms per liter across 158 results from 45 wells. Of these, iron was detected in 98 samples and was below the reporting limit in 60. Notably, none of these results exceeded any federal threshold for iron concentration.
Why Are Aesthetic Secondary Standards Different From Health-Based Limits for Iron?
Iron in water is typically regulated by aesthetic secondary standards, which focus on taste, color, and staining issues rather than health risks. These standards guide acceptable ranges to avoid unpleasant metallic taste or discoloration but are not health safety limits. Iron detections that comply with federal health-based criteria indicate the water is safe to drink despite any taste or appearance concerns.
What Do Terms Like 'Detected,' 'Median,' and 'Range' Mean in This Water Sampling Record?
In the sampling data, 'detected' means the instrument measured iron at or above its reporting limit. 'Median' is the middle value when all measured results are ordered, showing a central tendency rather than an average. The 'range' shows the lowest and highest iron levels found in the area samples. These terms describe area-wide conditions, not any single household's water.
How Many Samples and Wells Underpin These Figures, and What Does a Small Sample Size Imply?
The figures come from 158 samples taken from 45 wells over several months. This is a robust data set reflecting regional groundwater quality trends in aquifer 300CRSLN but not individual wells, which can differ significantly. Small sample sizes increase uncertainty; here, the moderate sample size offers reasonable confidence in the area’s typical iron occurrences.
What Household Symptoms Suggest Iron-Related Metallic Taste and Which Do Not?
Metallic taste linked to iron may coincide with reddish or brownish staining on fixtures, laundry discoloration, or sediment accumulation. However, metallic taste alone may stem from other causes like plumbing materials or different mineral content. Symptoms such as cloudy water, unusual odors, or staining unrelated to iron typically point to different issues.
What Should Be Checked First When Investigating Metallic Taste in Home Water?
- Start by inspecting household plumbing and faucets for corrosion or leaching metals.
- Flush stagnant water from pipes and test if taste improves.
- Conduct an at-home water test focusing on iron and other metals.
- If concerns persist, obtain comprehensive laboratory water testing to identify constituents causing the metallic taste.
How Does the Autotrol Metallic-Tasting Water Filter Address Iron-Related Taste?
The Autotrol System is designed to reduce metals contributing to metallic taste by filtering or oxidizing iron and similar constituents from groundwater. It ships ready to configure for residential setups, providing a practical treatment approach that targets the aesthetic issues without modifying water safety compliance.
This page reviewed regional water quality data indicating iron levels in Worcester County's aquifer 300CRSLN, clarifying aesthetic versus health standards. It outlined how to interpret area sampling results, recognize symptoms, and approach testing before considering treatment with the Autotrol Metallic-Tasting Water Filter.

Source: USGS groundwater sampling. Sampled 2018-11-08. 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.
