Government sampling from 27 wells in Portage County’s 100SDGV aquifer area finds iron detected in some wells in very low amounts, with no sample exceeding federal limits. This overview helps households whose existing water treatment has failed to assess total well water conditions based on public data.
1. A Worked Example: Reading the Record's Median and Range as a Homeowner Would
Median iron level found is 5.55 micrograms per liter
Range of results spans from 3.8 to 2860 micrograms per liter detected
Iron was detected in 14 of 59 samples taken across 27 wells
Majority of samples (45 of 59) showed iron below the reporting limit
2. Household Symptoms That Do and Do Not Point to This Problem
Visible reddish staining on sinks or fixtures may indicate iron presence
Metallic taste or discoloration in water suggests iron-related issues
Cloudy water without staining is less likely related to iron levels found
Frequent clogging in faucets and showerheads could be linked to mineral deposits
3. Which Fixtures, Appliances or Processes Are Affected First and Why
Bathroom fixtures often show stains earliest due to low flow and evaporation
Washing machines may experience buildup affecting clothing color
Water heaters can accumulate iron sediments, reducing efficiency
Ice makers may develop discoloration if untreated water source contains iron
4. What a Certified Laboratory Test for This Constituent Reports and How to Read It
Lab tests measure iron concentration in micrograms per liter (ug/L)
Results below reporting limits indicate iron is not detected in measurable amounts
Levels well below federal thresholds do not pose a health concern
Test results must be interpreted in context of household symptoms and water quality goals
5. How Seasonal or Multi-Year Variation Shows in the Record (Dates and Ranges Given)
Data covers samples from August 2011 through August 2024
Variability exists: some samples show low iron, others higher within the range
Seasonal effects on iron levels in groundwater are not explicitly detailed in this record
Long-term monitoring supports understanding of treatment needs over time
6. How Sample Depth, Well Depth or Source Type Changes What a Reader Should Expect
Wells sampled ranged from 12 to 140 feet deep in the aquifer
Deeper wells might show different iron levels than shallower ones
Individual well water quality can differ markedly from the area-wide sample median
Testing your own well is essential to know exact conditions for treatment
These 59 samples from 27 wells in Portage County’s 100SDGV aquifer area provide a regional snapshot of iron levels, none exceeding federal thresholds. For households with failed water treatment, using this public record alongside certified lab testing helps clarify treatment needs. The Pentair Total Well Chlorination System ships ready to configure and supports effective well water treatment for homeowners in this area. Full details of the government sampling are available at the U.S. Geological Survey monitoring location.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2024-08-20. 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.
