1. How Many Samples and Wells Support These Area Sulfur Findings?
The U.S. Geological Survey collected sulfide measurements from two wells within Kane County's aquifer 110QRNR, recording a total of three sample results during June 2010 to May 2011. This small dataset means the presence and range of sulfide detected reflect only a limited portion of the aquifer sampled at that time. Such a narrow sample size cannot represent the sulfide levels present in every well within the county, including your own.
2. What Role Do Sample Depth, Well Depth, and Source Type Play in What You Should Expect?
The sampled wells were relatively shallow, measuring between 24 and 38 feet deep. Since sulfide concentrations can vary with depth, water drawn from deeper or differently constructed wells may produce different results. Additionally, source type—whether a private well or a public supply drawing from this aquifer—affects water characteristics, so local water may not exactly mirror these sample findings.
3. What Should You Document Before Seeking Advice on Managing Sulfur Smell?
Before looking for treatment options, it is important to record your own water test results for sulfide or hydrogen sulfide from an accredited laboratory, including the measurement date and sample depth. Note which fixtures emit the odor, and whether the smell appears only under certain conditions. This information allows accurate evaluation and tailored solutions rather than relying solely on area sampling data.
4. How Do Seasonal or Multi-Year Changes Appear in These Records?
The sulfide samples were collected over an 11-month span from mid-2010 to mid-2011. Within that period, detected sulfide concentrations ranged from 0.002 to 0.07 mg/L with a median of 0.037 mg/L. This range indicates some variation but covers less than a full year and does not capture longer-term or seasonal fluctuations. Homeowners should consider testing during different seasons or years to understand their own water dynamics better.
5. How Do Public System Records Differ from Private Well Testing in What They Tell You?
The government data comes from specific wells sampled as part of a regional aquifer study, not routine municipal water quality tests. Public water systems typically monitor broader parameters and comply with federal health-based standards, which for sulfide show no violations in this area. Private well owners must perform their own testing to know if sulfur compounds are present and at what levels. Area sampling cannot replace individual well testing.
6. Which Household Fixtures and Processes Are Most Affected by Sulfur Smell?
Odor from sulfide compounds—often described as a rotten-egg smell—typically appears first in hot water supply lines, water heaters, and fixtures like taps or showerheads. This happens because sulfide gas can form or concentrate in warm water, increasing the smell's intensity. Cold water may show less odor. Understanding this can help direct testing and treatment efforts effectively.
Final Note: The sulfide levels reported for Kane County's aquifer 110QRNR reflect measurements in two wells during mid-2010 to mid-2011 and are below any federal thresholds for safety. These findings do not indicate your home's water has the same sulfide concentration or that the water is unsafe. To address sulfur smell in your household after equipment failure, consider the Autotrol Rotten-Egg Sulfur Smell Filter, which ships ready to configure and is designed to reduce these odors effectively based on your specific water test results.
Where this information comes from
Source: USGS groundwater sampling. Sampled 2011-05-31. 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 Sulfide in the 110QRNR aquifer (Kane County): 3 results from 2 wells, median 0.037 mg/L, range 0.002-0.07 mg/L; none above any federal threshold
