Interpreting Government Water Data Versus Your Household Water
The U.S. Geological Survey collected groundwater samples from six wells in Carlton County’s aquifer 112TILL in 2016, measuring iron concentrations. These area-wide results provide a useful context but cannot specify the iron content or iron bacteria presence in your household well. Only a well-specific water analysis can confirm conditions in your water supply after your existing equipment has failed.
Why Aesthetic Secondary Standards Differ from Health-Based Limits for Iron
Iron in groundwater is regulated by aesthetic secondary standards rather than health-based limits. These secondary standards address effects such as taste, staining of plumbing fixtures, and discoloration, not direct health risks. The U.S. Geological Survey data from Carlton County show all iron measurements were below any federal health threshold, indicating no health violation recorded at the sampled wells.
How Iron Enters Groundwater in the Carlton County Region
Iron in the aquifer 112TILL typically originates from natural geochemical sources in soil and rock. In this region, iron is mobilized into groundwater through soil mineral dissolution and groundwater flow. Iron bacteria thrive where iron and organic matter provide a food source, forming slimy biofilms that can clog plumbing and damage equipment over time.
Steps to Rule Out Causes Before Choosing Treatment
Begin by visually inspecting water for reddish or brownish staining and slime formation, common signs of iron bacteria. Test water chemistry with a basic iron test kit to estimate iron levels. For a precise diagnosis, collect a lab water sample analyzed specifically for iron bacteria presence and total iron content. This step distinguishes whether iron bacteria or other iron forms are causing your issues.
Understanding 'Detected', 'Median', and 'Range' in Government Sampling
All six sampled wells in Carlton County’s aquifer 112TILL showed iron detected, with a median concentration of 301.5 micrograms per liter and a range from 13.7 to 609.0 micrograms per liter. Detected means the instrument measured iron; it is not a safety violation or guarantee of an issue. The median represents the middle value of measurements, and the range shows variability across wells sampled at 35 to 148 feet depths.
Assessing Treatment Capacity for Your Household’s Daily Water Use
Once iron bacteria presence and iron concentration are confirmed by testing, consider your household's daily water demand when selecting treatment equipment. The C-Series Iron Bacteria & Slime Filter system ships ready to configure and offers scalable capacity to match residential water use, ensuring reliable performance where previous equipment has failed.
Summary: Area data from Carlton County aquifer 112TILL provide background on iron levels but cannot substitute for direct testing of your household water. Accurate diagnosis through testing guides appropriate treatment capacity decisions. The C-Series System addresses iron bacteria effectively when chosen to fit your specific water needs.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2016-05-13. 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 112TILL aquifer (Carlton County): 6 results from 6 wells, median 301.5 ug/L, range 13.7-609.0 ug/L; none above any federal threshold
