Reading Cleveland County’s Iron Data as a Homeowner
Median iron concentration across sampled wells
The U.S. Geological Survey recorded a median iron level of 12.5 micrograms per liter (µg/L) from six wells in Cleveland County’s aquifer 318GRBR between May 2012 and May 2013. This median reflects typical regional groundwater iron concentrations, not any individual well.
Range of iron concentrations found in samples
Iron was detected at values ranging from 3.3 to 85.2 µg/L in 26 of 41 samples. Fifteen samples had iron below the reporting limit. These readings come from wells between 360 and 698 feet deep.
How Treated Water Changes at the Tap with the Pentair Iron Bacteria & Slime Filter
Reduction of iron bacteria and slime-related deposits
Using the Pentair Iron Bacteria & Slime Filter helps households reduce iron bacteria that cause staining, slime buildup, and bacterial growth in plumbing systems, improving water clarity and fixture appearance.
Improved water aesthetics and system longevity
Filtering iron bacteria can decrease iron-derived deposits and slime, leading to fewer maintenance needs for faucets, appliances, and pipes commonly affected by these issues.
Effects of Sample Depth and Well Characteristics on Expected Water Quality
Sample depth range in regional data
Data reflects wells sampled at depths from 360 to 698 feet, indicating that iron concentrations reported pertain to relatively deep groundwater sources and may vary with shallower or differently constructed wells.
Implications for individual wells
Because water quality changes with depth and well construction, homeowners should test their well water specifically to understand their iron bacteria conditions rather than relying solely on regional data.
Fixtures and Appliances Most Affected First by Iron Bacteria
Water heaters and dishwashers
Iron bacteria deposits tend to accumulate first in appliances exposed to warm water, such as water heaters and dishwashers, where slime formation can impair function.
Faucet aerators and showerheads
These fixtures frequently experience clogging or staining due to iron bacteria-related slime, affecting flow rates and water appearance.
Sample Size and Scope Behind Cleveland County’s Iron Figures
Number of samples and wells in the USGS dataset
The dataset includes 41 samples collected from 6 separate wells over a one-year period, providing a snapshot but not a comprehensive survey of all groundwater in the county.
Limitations of regional data for individual assessments
While useful for general trends, this data does not determine the iron bacteria level in any single residential well; direct testing by homeowners is necessary for precise water quality evaluation.
Additional Questions for Commercial or Industrial Considerations
Volume and flow rate demands
Commercial operators must consider how iron bacteria might impact higher water usage and longer operational timelines compared to households.
Compliance and regulatory factors
Businesses may have specific reporting requirements or treatment standards that exceed household needs, influencing their treatment choices.
Summary: Regional groundwater sampling in Cleveland County’s aquifer 318GRBR shows iron at typical concentrations with no federal thresholds exceeded, but individual well testing is essential. The Pentair Iron Bacteria & Slime Filter offers households a ready-to-configure option to address iron bacteria’s effects on water quality and home plumbing.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2013-05-01. 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 318GRBR aquifer (Cleveland County): 41 results from 6 wells, median 12.5 ug/L, range 3.3-85.2 ug/L; none above any federal threshold
