What do lab reports typically show for sulfide in York County aquifer 122PNPN water?
Laboratory testing results reported by the U.S. Geological Survey for this area list sulfide concentrations measured in groundwater. Tests from three wells sampled between 2010 and 2016 showed sulfide levels detected in all samples, with a median concentration of 0.023 mg/L and a range from 0.0 to 0.036 mg/L. None of these values exceeded federal thresholds for safety. These samples originated from wells 245 to 446 feet deep, representing regional aquifer conditions rather than individual household wells.
How does sulfide concentration vary seasonally or over multiple years in this data set?
The sampling dates spread over a six-year period suggest relative stability or modest variation in sulfide levels over time within the aquifer. The range of detected levels remains narrow, indicating no dramatic shifts during that interval. This helps frame homeowner expectations of typical odor potential related to sulfide content without implying precise predictions for any single well.
Does well or source depth influence the sulfide levels and sulfur smell in household water?
Yes. The sampled wells are moderately deep, from 245 to 446 feet, representing groundwater from this aquifer zone, which tends to have detectable but low sulfide. Shallower or different water sources could produce different odors or sulfide levels. Homeowners should consider their own well’s depth and source characteristics when evaluating the likelihood and severity of sulfur smell.
What changes can be expected in tap water odor after using the C-Series Rotten-Egg Sulfur Smell Filter?
This filtration system is designed specifically to reduce sulfur-related odors in residential water supplies. Once configured and in use, it typically decreases or removes the characteristic rotten-egg smell caused by sulfide compounds. This results in noticeably fresher-smelling tap water while maintaining water quality and safety.
How is sulfur smell from sulfide different from other common water odor issues?
Sulfur smell primarily arises from sulfide compounds in source water. Other odors or tastes in water might come from bacterial contamination, iron or manganese presence, or plumbing issues unrelated to sulfide. Correctly identifying sulfide as the source is key to choosing the appropriate treatment approach, such as the C-Series system.
How can a homeowner interpret the median and range values from the sampling record?
The median value, 0.023 mg/L, represents the middle concentration level across the three samples, while the range (0.0 to 0.036 mg/L) shows the lowest and highest detected sulfide levels. These reflect a typical regional background rather than a precise reading for any household. They help suggest the potential for mild sulfur odors but do not predict individual well conditions.
What do terms like 'detected', 'median', and 'range' mean in the context of this sampling data?
'Detected' means the instrument measured sulfide present at or above the laboratory’s reporting limit. 'Median' is the middle value in the data set, providing a representative concentration. 'Range' indicates the span between the lowest and highest detected concentrations. None imply contamination or health risk on their own.
What water test should a homeowner order to confirm sulfur odor levels and treatment needs?
The best step for any household experiencing sulfur smell concerns is to order a sulfide-specific water test from a qualified laboratory. Results directly from their tap water will determine actual sulfide concentrations and the necessity of treatment. This test clarifies whether solutions like the C-Series Rotten-Egg Sulfur Smell Filter will address their specific water conditions.

Source: USGS groundwater sampling. Sampled 2016-06-14. 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.
