Government Sampling Shows Sulfide Present in Citrus County Aquifer 120FLRD

The U.S. Geological Survey sampled groundwater in Citrus County, FL, specifically from the 120FLRD aquifer. From six samples taken between December 2011 and December 2012 from three wells between 31 and 150 feet deep, sulfide was detected in four results with a median concentration of 0.075 mg/L and a range of 0.03 to 0.1 mg/L. No sample exceeded federal thresholds for sulfide concentration.

Common Household Signs Associated with Sulfur Smell

Residences experiencing a sulfur or rotten-egg odor often notice it primarily from tap water, especially when drawing hot water or using water heaters. This smell is typically caused by sulfide compounds or hydrogen sulfide gas dissolved in the water. However, not all unpleasant water odors stem from sulfide; sometimes, bacterial activity or other water chemistry factors may cause similar smells or tastes that require different approaches.

It is important to recognize that the presence of a sulfur smell alone does not confirm the sulfide levels or water quality in your individual well or water supply. Further testing at a certified laboratory is necessary for an accurate assessment.

How Certified Laboratory Testing Reports Sulfide Levels

When you send a water sample to a certified lab for sulfide analysis, the result will usually be reported in milligrams per liter (mg/L). The test detects dissolved sulfide compounds, including hydrogen sulfide, which contribute to the sulfur odor. Lab reports might also indicate if the measured concentration is above or below the laboratory’s detection limit but will not assess whether the level is a health violation.

Understanding Measured Sulfide Levels Versus Federal Standards

The sulfide concentrations observed in Citrus County’s aquifer are below any federal health-based limits. Sulfide is mainly subject to aesthetic secondary standards focused on taste, odor, and water appearance, rather than safety limits. Even when sulfide is detected, it does not imply the water is unsafe. Instead, concentrations above certain thresholds might cause unpleasant smells or corrosivity that can affect plumbing or laundry.

Therefore, the detection of sulfide in your water area does not necessarily indicate a health risk, but it may explain an odor issue that you want to address for comfort and convenience.

Distinguishing Sulfur Smell from Other Water Odors

Not all bad water odors are due to sulfide. For example, chlorine or chloramine treatment in municipal water can sometimes produce smells that might be confused with sulfur. Similarly, organic matter or iron bacteria growth can create earthy odors. Testing specifically for sulfide helps clarify whether the rotten-egg smell is linked to dissolved sulfides or other causes.

Knowing the exact cause of the odor is essential to choosing an appropriate solution. For sulfide-related odors, specialized filters designed to reduce sulfur smell can be effective.

Addressing Sulfur Smell with the Autotrol Rotten-Egg Sulfur Smell Filter

A documented solution to reduce sulfur odors is the Autotrol Rotten-Egg Sulfur Smell Filter. This system ships ready to configure and uses technology designed to treat water with sulfide presence, improving water smell without the need for complex setup.

Because the government’s sampling covers wells 31 to 150 feet deep in Citrus County’s 120FLRD aquifer and detected sulfide within a known range, this product can help households experiencing typical sulfur odors consistent with these conditions.

Summary of Area Sampling and Next Steps

The USGS groundwater data in Citrus County’s 120FLRD aquifer sampled wells at various depths over 2011–2012 and detected sulfide concentrations below federal thresholds in most instances. This record describes the area but does not establish the condition of any individual household water. Confirming your water’s sulfide level requires a certified lab test. For households where sulfur smell is an issue consistent with these findings, the Autotrol Rotten-Egg Sulfur Smell Filter offers an effective remedy.
