What Area Data Can and Cannot Reveal
Government groundwater sampling in New Hanover County's aquifer 211PEED shows that iron was detected in 61 out of 66 water samples, collected from 46 separate wells between August 2012 and May 2017. These wells ranged in depth from 42 to 220 feet. The median iron concentration measured was 57.2 micrograms per liter, with a range from 3.4 to 11,400 micrograms per liter. None of these results exceeded any federal health threshold for iron. It is important to understand that these measurements describe iron presence in the area aquifer—not the specific iron level in any individual household well water. Only a specific test of your well can determine your water’s iron content or the presence of iron bacteria specifically affecting your household water.
How Iron Levels Vary Over Time in Area Sampling
Sampling spanned almost five years from 2012 to 2017
Iron concentrations showed wide variation among wells
Repeated samples reflect multi-year fluctuations in iron
Seasonal changes may influence iron presence in groundwater
How Iron Enters Groundwater in New Hanover County
Natural geological sources release iron into aquifer 211PEED
Iron bacteria thrive in groundwater where iron is present
Iron bacteria form slime or biofilms in well and plumbing systems
Iron in water can be both dissolved and particulate
Distinguishing Iron Bacteria From Similar Water Issues
Iron bacteria cause slime and staining, unlike simple iron presence
Iron bacteria are living organisms, not chemical contaminants
They differ from sediment issues which involve non-living particles
Unlike general iron staining, iron bacteria produce musty odors and slimy deposits
How Water At the Tap Changes With the Documented Treatment
The Fleck Iron Bacteria & Slime Filter targets iron bacteria and associated slime
Water clarity may improve with reduced biofilm and iron deposits
Taste and staining caused by iron bacteria can decrease
The system ships ready to configure for household water treatment
Additional Considerations for Commercial or Industrial Operations
Operational scale may require different flow capacity or maintenance timing
Process water quality needs may include higher monitoring frequency
Impact on equipment and production lines may add testing requirements
Regulatory compliance for commercial water use involves further water quality parameters
Summary of Area Sampling Scope
This groundwater sampling record covers 46 wells between 42 and 220 feet deep within New Hanover County’s aquifer 211PEED, collected from 2012 through 2017. It provides a regional snapshot of iron occurrence but does not specify individual household water conditions. For household-specific concerns, including iron bacteria presence and treatment options, water testing of the home supply is essential. Interested readers can consult the original U.S. Geological Survey data source for detailed monitoring information.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2017-05-25. 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.
