What Causes Sulfur and Methane Gases in Water, and How Are They Removed?

Sulfur and methane gases can form naturally underground and enter well water supplies. Sulfur is often noticed as a rotten egg smell, while methane may cause bubbling water or trapped gas in plumbing. These issues are more common in private wells and can vary based on soil conditions, water depth, and local geology.

Dissolved gases in water can be damaging to piping systems and cause wear on valves, seals, and washers. Treatment depends on the source and gas levels.

Common solutions include aeration systems, oxidation, activated carbon filters, and other custom treatment equipment. Water testing is the first step to identify the problem and choose the right solution.

Our Sanitizer Series may be the appropriate treatment method. In severe cases of hydrogen sulfide and methane gas, we also offer the Sentry Open-Air, a system that is like your own private water treatment plant.

If you only notice a rotten egg odor when using hot water, the problem may be fixed by simply having your water heater serviced.
