HYDROGEN SULFIDE / ROTTEN EGG SMELL

rotten egg smell in water Franklin MA

Hydrogen sulfide and sulfate-reducing bacteria are two forms of sulfur most commonly found in drinking water supplies. Both forms are nuisances that usually do not pose a health risk at the concentrations found in domestic wells, but can cause major aesthetic problems in your Franklin home if present. This gas, which causes a rotten egg smell in water, occurs naturally in certain ground waters containing decaying organic matter, such as marshes, swamps, wetlands and river beds. It may be found in either deep or shallow wells. Hydrogen sulfide is often present in wells drilled in shale or sandstone, or near coal or peat deposits or oil fields and is corrosive to metals such as iron, steel, copper and brass and can tarnish silverware and discolor copper and brass utensils. It can also cause yellow or black stains on kitchen and bathroom fixtures.

Coffee, tea and other beverages made with water containing hydrogen sulfide may be discolored and the appearance and taste of cooked foods can also be affected. High concentrations can foul the resin bed of an ion exchange water softener.

WATER TESTING FOR HYDROGEN SULFIDE (H2S)

Hydrogen sulfide can be difficult to test because the gas escapes into the atmosphere so quickly. Onsite testing is the most accurate method for determining concentration, especially if the odor is excessive. The odor is difficult to mistake.  Concentrations greater than 5 mg/L are more difficult to treat and could require special testing methods to assure accuracy.

WATER TREATMENT SOLUTIONS

Hydrogen sulfide treatment is with chlorination, aeration followed by filtration or ozone infusion. Often, treatment for hydrogen sulfide is the same as for iron and manganese, allowing the removal of all three contaminants in one process. Based on the total water chemistry, the best approach can be determined.

IF ROTTEN EGG SMELL IS IN THE HOT WATER ONLY

Most water heater anode rods contain some sulfate therefore, If the water contains sulfate-reducing bacteria, a rotten egg odor is created in the hot water only. If this occurs, the first course of action is to replace the anode rod with an aluminum-based rod which limits the sulfate and therefore stops the odor.  Sulfate-reducing bacteria is treated with continuous chlorination. Removing sulfate mineral is difficult and usually not feasible, so chlorination kills the bacteria instead. The chlorination process involves a chemical feed pump system that injects a chlorine solution into the inlet of a retention tank that must be installed in the house piping. There are other considerations as well in this process which can be discussed with your water treatment professional.
