Deciding whether to treat iron bacteria in your household water involves knowing how the problem differs from similar issues and how it matches your daily water use.
Distinguishing Iron Bacteria from Other Common Water Issues
Iron Bacteria vs. Rust or Iron Stains
Unlike rust or iron stains caused by dissolved iron oxidizing in water, iron bacteria form slime colonies that can create clumps and slick surfaces in pipes or tanks.
Iron Bacteria vs. Iron in Solution
Iron bacteria are living microorganisms that consume iron, whereas dissolved iron is a chemical constituent. This biological presence can lead to clogging and a slimy residue.
Matching Treatment Capacity to Household Water Use
Estimate Your Daily Water Demand
Calculate household water use based on family size and typical activities like cooking, cleaning, and bathing to select the right treatment system size.
Consider Peak Usage Times
Water use varies during the day. Treatment equipment must handle peak flows without losing effectiveness.
Iron Bacteria Presence in Berkeley County's Groundwater
Source of Iron in the Local Aquifer
Iron in Berkeley County’s 120FLRD aquifer naturally occurs from rock and soil minerals dissolving over time. Iron bacteria feed on this iron when conditions in wells favor their growth.
Depth of Sampled Wells
Government sampling included wells between 110 and 280 feet deep, reflecting typical household groundwater sources in the area.
Understanding Certified Laboratory Testing for Iron
What Test Results Report
Lab results show iron concentration in micrograms per liter (ug/L). For Berkeley County samples, iron was detected in 5 out of 8 tests, ranging from 3.8 to 3,710 ug/L, with a median of 430 ug/L.
Importance of Your Own Water Test
Because these figures reflect area wells, only a certified test of your household water can reveal your specific iron level and help assess iron bacteria presence.
Comparing Berkeley County's Iron Bacteria Data with Adjacent Areas
Variability Within Nearby Regions
Iron levels can vary widely even within small geographic areas due to geology and well depth. Neighboring counties may have different median or range values.
Avoid Overinterpreting Regional Data
The presence of iron in area samples does not guarantee your water contains iron bacteria or iron at the same concentrations.
Summary and Where to Learn More
This page reviewed iron bacteria data based on U.S. Geological Survey sampling of Berkeley County’s 120FLRD aquifer wells from 2011 to 2018. Your well’s condition may differ; a certified water test is essential. For detailed groundwater data, visit the U.S. Geological Survey at waterdata.usgs.gov.
For treatment, the Autotrol Iron Bacteria & Slime Filter ships ready to configure to address iron bacteria specifically, sized according to your household demand.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2018-08-30. 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 120FLRD aquifer (Berkeley County): 8 results from 7 wells, median 430.0 ug/L, range 3.8-3710.0 ug/L; none above any federal threshold
