HYDROGEN SULFIDE REMOVAL

IS HYDROGEN SULFIDE CAUSING A ROTTEN EGG SMELL ?

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 Plainville home.

A BAD EGG

Hydro­gen sul­fide 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.

Hydro­gen sul­fide gives water a “rot­ten egg” smell and taste, and can cause nau­sea.  It is cor­ro­sive to met­als such as iron, steel, cop­per and brass. It 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 of dis­solved hydro­gen sul­fide also can foul the resin bed of an ion exchange water soft­en­er.

WATER TESTING FOR HYDROGEN SULFIDE 

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.  For con­cen­tra­tions greater than 5 mg/L are more dif­fi­cult to treat and could require spe­cial test­ing meth­ods to assure accu­ra­cy.

The EPA sets stan­dards for sec­ondary water con­t­a­m­i­nants based on col­or, odor, taste, cor­ro­sive­ness, foam­ing and stain­ing prop­er­ties. Hydro­gen sul­fide is not reg­u­lat­ed because any con­cen­tra­tion high enough to pose a health haz­ard will also make the water too unpalat­able to drink.

WATER FILTRATION OPTIONS

Hydro­gen sul­fide can be treat­ed with chlo­ri­na­tion, aer­a­tion fol­lowed by fil­tra­tion or ozone infu­sion. Depend­ing on the H2S lev­el present in the water, a deter­mi­na­tion can be made by your water treat­ment pro­fes­sion­al as to which method will be most effec­tive.  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.

HYDROGEN SULFIDE WATER FILTRATION SYSTEMS

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.
