This week, if your existing well treatment equipment has failed, the key decision is how to address total well water quality issues effectively in Fresno County's aquifer S100CNRLVL.
Myth: Plumbing Age Is the Main Cause of Water Quality Issues
While the materials and age of plumbing can influence water taste and staining, government groundwater sampling in Fresno County focuses on the source water quality itself. Plumbing issues are separate from the total well water characteristics that sampling captures from deep aquifers. Replacement of equipment addressing only plumbing materials will not resolve water quality concerns detected in the source water.
Myth: Detection Means Unsafe or Violative Levels in Your Well
Between 2010 and 2023, the U.S. Geological Survey sampled 131 results from 50 wells in the Fresno County aquifer S100CNRLVL at depths ranging from 78 to 2109 feet. Chloride was detected in 129 results, with a median of 31.4 mg/L and a range from 1.67 to 1350 mg/L. Two results were below reporting limits. A detection means the constituent was measured, not that it exceeds any health-based limit or presents safety concerns. Additionally, 14 results were above the secondary aesthetic threshold of 250 mg/L, which relates only to taste and staining, not health or legal violation.
Myth: Commercial and Industrial Water Questions Apply to Households
Commercial or industrial users often evaluate total dissolved solids or treatment capacity differently. They consider system grain capacity or regulations specific to production needs, which households typically do not. For homeowners, the focus is on reliable water quality for daily use, with a treatment system matched to typical residential water volumes and contaminants. Such a system must handle up to 32,000 grains capacity to maintain effectiveness.
Myth: Certain Household Symptoms Always Indicate a Total Well Water Problem
Household symptoms like staining, taste issues, or corrosion can arise from various causes beyond total well water quality, including plumbing condition or localized contamination. Conversely, the absence of obvious symptoms does not rule out water quality challenges. Water testing of your specific well is essential to confirm conditions and tailor treatment accordingly.
Myth: Sample Depth and Well Depth Do Not Affect Water Quality Expectations
In Fresno County, samples derive from wells between 78 and 2109 feet deep. Deeper wells may show different water chemistry profiles than shallow ones due to geological layers and aquifer composition. Source water type and well depth directly influence what constituents are present and in what concentrations, so your own well test is crucial to understand your water.
Myth: Complex Maintenance is Required for Effective Treatment
The C-Series Total Well Chlorination System ships ready to configure for household use, designed to address total well water challenges reliably. Maintenance follows a straightforward rhythm suited to residential needs, helping to maintain effective oxidation and disinfection without specialized service requirements. Regular upkeep supports consistent water quality over time.
What Not to Conclude from Area Sampling Data
The government sampling record provides valuable context for the aquifer’s general water quality but cannot substitute for testing your well water directly. Detected chloride levels in the regional data do not establish your well’s specific concentration, and aesthetic thresholds do not imply health risks. Making treatment decisions requires knowledge of your exact water conditions, which can only come from representative well testing combined with solution options like the C-Series System tailored to your household water needs.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2023-05-10. 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 Chloride in the S100CNRLVL aquifer (Fresno County): 131 results from 50 wells, median 31.4 mg/L, range 1.67-1350.0 mg/L; 14 above an AESTHETIC secondary standard only (secondary standard 250.0 mg/L (aesthetic)) - not a health finding
