What does the government data tell us about sulfur smell in San Juan County's aquifer?

Government sampling of groundwater in San Juan County, specifically the 110AVMB aquifer, provides a helpful regional picture but does not reveal the exact condition of any single household's water supply. From April 2021 to September 2025, 72 samples from 8 wells located between 35 and 68 feet deep were analyzed for sulfide, a compound associated with sulfur smell.

Out of these, 62 samples detected sulfide with amounts ranging from 0.002 to 4.6 milligrams per liter (mg/L), and the median value was 0.039 mg/L. It is important to note that no measurements exceeded any federal thresholds, which means no legal limits for health or safety concerns were surpassed. However, detections alone do not indicate a problem for your specific well, only the presence of sulfide in some parts of the aquifer.

How does the Autotrol Rotten-Egg Sulfur Smell Filter address sulfur smell?

When sulfur smell results from sulfide presence in water, effective treatment focuses on removing or neutralizing sulfide compounds before the water reaches faucets. The Autotrol Rotten-Egg Sulfur Smell Filter is designed to reduce or eliminate the sulfur odor by filtering out sulfide and related compounds.

This system works through specialized filtration media tailored to trap sulfide and neutralize the characteristic rotten-egg smell. Since your current equipment operates but struggles to keep up, this filter can supplement or replace your existing system, helping maintain better water quality and reducing unpleasant odors.

What information should I have ready before seeking treatment advice?

Before pursuing treatment options, carefully document your own water test results, focusing on sulfide concentration and any odor concerns. Testing should be done on your household water to determine exact sulfide levels and confirm the sulfur smell issue.

Also note the current performance of your water system and any fluctuations in odor or water quality over time. This information helps in selecting appropriate treatment and ensures compatibility with solutions like the Autotrol Rotten-Egg Sulfur Smell Filter.

What do the terms 'detected,' 'median,' and 'range' mean in this context?

'Detected' means the measurement instrument found sulfide present at a level measurable above the reporting limit, but not necessarily at a problematic concentration. 'Median' indicates the middle value when all sample results are arranged from lowest to highest, offering an idea of typical sulfide levels in the area.

'Range' describes the span between the lowest and highest sulfide values recorded in the samples. Together, these terms help describe the variability and typical concentrations seen across multiple wells, not a single household’s water.

How do sample depth and well characteristics affect sulfide levels I might encounter?

The sampled wells ranged from 35 to 68 feet deep. Variations in well depth, construction, and water source type can influence sulfide presence and concentration in your home’s water.

Deeper or differently constructed wells may access water with different sulfide levels than the sampled regional wells, so your individual water test results are essential for accurate information about your water quality.

Summary of San Juan County Sulfide Sampling and What It Means for You

The U.S. Geological Survey data for San Juan County's aquifer 110AVMB reflects sulfide presence in many nearby wells but no federal limit exceedances. This regional data points to the possibility of encountering sulfur smell but cannot specify your well’s condition. Testing your water is necessary to confirm sulfide levels.

If sulfur smell is confirmed and current treatment systems are insufficient, the Autotrol Rotten-Egg Sulfur Smell Filter ships ready to configure and offers an effective way to reduce or remove sulfide odors from your household water.
