Water quality in McHenry County, specifically from aquifer 110QRNR, reflects regional characteristics that influence household treatment needs. Government sampling by the U.S. Geological Survey from 55 wells found hardness present in every sample ranging from 161.0 to 851.0 mg/L, with a median value of 423.0 mg/L. These results are from wells between 13 and 344 feet deep and are available for this particular aquifer, not for any individual residential well.
If you want to know how treated water differs at your tap
The Fleck Acidic Water + Hard Water (Well) System ships ready to configure and is designed to reduce hardness and neutralize acidity. Once configured, it softens water by exchanging hardness minerals such as calcium and magnesium while addressing acidity to protect plumbing and improve water feel. Treated water generally results in less scale buildup and can extend the life of appliances and fixtures sensitive to mineral deposits.
If you consider the influence of your home's plumbing material and age
The effects of acid and hardness on water depend partly on plumbing materials and their age. Older or metal plumbing can react differently with acidic or hard water compared to newer or plastic piping. Acidic water may contribute to pipe wear or corrosion independently from hardness. Therefore, determining the plumbing context helps understand water quality impact before deciding on treatment.
If you want a logical order to rule out water quality concerns
- First, note that regional data do not replace a specific test of your own well or tap water; professional lab testing is essential to determine your household's unique water profile.
- Test for hardness (calcium and magnesium) and pH levels to detect acidity.
- Consider additional parameters if plumbing issues are present, but hardness and acidity remain the core focus for this system.
If you need to match treatment capacity to your household's water usage
The Fleck System offers a 32,000 grain capacity, a measurement of hardness removal capability. Selecting the right capacity means comparing this to your daily water use and estimated hardness levels. Larger households or higher hardness values require proportionately greater capacity to maintain consistent treated water availability.
If you want to prepare information before seeking treatment guidance
- Record test results for water hardness and pH from a certified laboratory.
- Note household water consumption rates.
- List plumbing materials and any known issues connected to water quality.
- Capture data on well depth and source if available.
If your household is large, a second home, or seasonal property
Large households or properties with irregular water use patterns may need increased treatment capacity or settings adjusted for intermittent demand. The Fleck System’s configurable grain capacity can accommodate these situations but requires planning based on usage cycles and hardness levels.
The data discussed here come from the U.S. Geological Survey’s sampling of aquifer 110QRNR in McHenry County, covering 147 hardness measurements from 55 wells sampled from 2010 to 2021. These findings describe regional water quality trends and do not indicate individual well conditions. For a detailed view of your water, laboratory testing is necessary. Visit the USGS groundwater data portal for comprehensive regional information.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2021-05-27. 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 Hardness, Ca, Mg in the 110QRNR aquifer (McHenry County): 147 results from 55 wells, median 423.0 mg/L, range 161.0-851.0 mg/L; none above any federal threshold
