Many households in Harrison County notice a faint metallic taste when drinking tap water. This subtle flavor can be the first sign that minerals detected in local groundwater affect water quality in everyday use.
Seasonal and Multi-Year Variation in Regional Sampling
Sampling Dates Range from 2010 to 2015
Groundwater samples from Harrison County's aquifer 122PCGL were collected over a five-year period between April 2010 and April 2015, providing insight into the typical range of mineral levels in this area across seasons and years.
Median and Range Demonstrate Fluctuation
The iron levels measured ranged from as low as 3.3 micrograms per liter (ug/L) to a maximum of 462.0 ug/L, with a median concentration of 7.6 ug/L. This variation shows that metallic taste can fluctuate depending on the specific time and location where water samples are taken.
Meaning of 'Detected,' 'Median,' and 'Range' in Government Sampling
'Detected' Indicates Presence, Not Severity
Iron was detected in 47 of 66 results, meaning instruments measured iron presence. Detection does not imply a health or safety concern but indicates a factor that may influence water taste.
Median Reflects Central Tendency
The median value of 7.6 ug/L represents the middle point in the dataset, giving households an estimate of typical iron concentration in regional groundwater.
Range Captures the Full Spectrum of Measurements
The range from 3.3 to 462.0 ug/L illustrates variation across wells and depths, helping users understand the potential extent of metallic taste impact in Harrison County water.
Fixtures and Appliances First Affected by Metallic Taste
Drinking Water Taps Often Reveal Metallic Flavors First
Fixtures such as kitchen faucets typically are the first place residents notice metallic taste, as these provide direct consumption water.
Ice Makers and Coffee Machines Can Accentuate Taste
Appliances that process water for consumption, like ice makers and coffee machines, may highlight subtle metallic notes more distinctly due to chilled or heated water.
Dishwashers May Experience Staining, But Not Taste Issues
Though metallic taste is less relevant here, mineral deposits can cause spotting on glassware, indirectly signaling mineral presence.
Differences Between Public System Records and Private Well Testing
Public System Data Offers a Regional Overview
Harrison County aquifer data come from multiple wells ranging in depth from 433 to 1300 feet, giving a wide perspective on groundwater conditions rather than specific home water quality.
Private Well Testing Is Required for Household Accuracy
To know the exact mineral concentrations in a specific household's water, individual testing is essential since regional data do not reflect the particular well or municipal tap.
Public Records Show No Federal Threshold Exceedances
None of the sampled results exceeded federal water quality thresholds for iron, indicating no regulatory violations in the region during the sampling period.
Sample Size and Its Impact on Interpretation
66 Samples from 42 Wells Provide Moderate Coverage
The dataset includes 66 samples taken from 42 separate wells, supplying a useful but not exhaustive understanding of the area's groundwater quality.
Small Samples May Miss Localized Variations
While informative, these samples might not capture all localized iron fluctuations, making household-specific testing advisable for precision.
Well Depth Variation Affects Comparability
Wells sampled varied in depth and thus may reflect different underground strata, influencing iron presence and taste impacts.
Households experiencing metallic taste consistent with regional data can consider the Pentair Metallic-Tasting Water Filter. This system ships ready to configure and is designed to reduce metallic flavor, helping users meet their household water taste demand based on personal water testing results.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2015-04-30. 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 122PCGL aquifer (Harrison County): 66 results from 42 wells, median 7.6 ug/L, range 3.3-462.0 ug/L; none above any federal threshold
