How to compare this area's record with a neighbouring county's without overreading it

Sample size and frequency

In Bristol County's aquifer 112SRFD, seven separate wells were sampled over approximately two and a half years, from mid-2010 to late 2012. These samples indicate the presence of sulfide in the local groundwater but represent only part of the broader aquifer and its variations.

Range and median values

The measured sulfide concentrations across these wells ranged from 0.0 to 0.5 mg/L, with a median of 0.1 mg/L. Neighboring counties may show different values depending on geology and well depth, but one should avoid assuming these regional data directly reflect the full character of a private well.

Interpreting the data cautiously

While this data shows sulfide was detected in all sampled wells, detection is not equivalent to a violation or an unsafe condition. Each property's water chemistry can differ, so local results provide context but not a precise water quality profile for any individual home.

What a certified laboratory test for sulfide reports and how to read it

Test scope and method

A certified lab test measures sulfide concentration in milligrams per liter (mg/L), quantifying the amount dissolved in a water sample from your specific source. This differs from regional monitoring, as it targets your home's water directly.

Understanding detection versus limits

Detection indicates sulfide presence but does not mean the water exceeds any federal health or secondary standards. The federal system includes thresholds mainly to protect taste, odor, and plumbing materials rather than human health.

Result interpretation

Results from your test will provide a definitive concentration for your water supply. These results are essential to decide if treatment is advisable to reduce sulfur smell or other related issues.

What distinguishes this problem from the two problems most often confused with it

Sulfur smell versus rotten egg odor from other sources

Hydrogen sulfide gas dissolved in water is the usual cause of sulfur smell, often described as a rotten egg odor. However, similar odors can come from bacterial activity in plumbing or water heaters, which may not be related to aquifer sulfide levels.

Distinguishing from iron or manganese staining

Sulfur smell does not cause rust-colored stains—that usually indicates iron or manganese. Confusing these can lead to ineffective treatment if the actual cause of odor is not properly identified.

What happens when this problem is left untreated for years, stated without exaggeration

Persistent odor discomfort

Ongoing sulfur smell can affect the taste and smell of drinking water, making it unpleasant for household use such as cooking and bathing.

Potential plumbing issues

Although not a health risk at detected levels, sulfide presence may contribute to corrosion or damage to some plumbing materials over a long period, particularly in certain pipe types.

Impact on water heaters

Hydrogen sulfide can react with the metal in water heaters, sometimes causing sediment buildup or odors from the hot water supply.

How the constituent enters groundwater or the distribution system in this region

Natural geochemical processes

Sulfide in Bristol County's aquifer 112SRFD originates mainly from natural reduction of sulfate minerals underground, often influenced by organic material and low oxygen conditions typical of shallow wells.

Depth relation

The wells sampled ranged from 20 to 66 feet deep, indicating sulfide presence in relatively shallow to moderate-depth groundwater sources.

Possible influence from infrastructure

In municipal systems, sulfide presence can also be influenced by distribution system conditions, but Bristol County's aquifer data specifically reflects groundwater chemistry.

Closing checklist item

The single test to order is a certified laboratory analysis of sulfide concentration from your household water source. A result showing noticeably elevated sulfide relative to the local median can confirm the cause of sulfur smell and help decide if treatment with a product like the Autotrol Rotten-Egg Sulfur Smell Filter, which ships ready to configure for home use, is appropriate.

Where this information comes from

Source: USGS groundwater sampling. Sampled 2012-11-05. 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 112SRFD aquifer (Bristol County): 7 results from 7 wells, median 0.1 mg/L, range 0.0-0.5 mg/L; none above any federal threshold
