WHY DOES MY WATER HAVE A ROTTEN EGG SMELL?

rotten egg smell in my water

The most preva­lent cause of rot­ten egg smell in water in this region is hydro­gen sul­fide.  Hydro­gen sul­fide is a col­or­less gas that can exist nat­u­ral­ly in ground­wa­ter. Sul­fur-reduc­ing bac­te­ria present in ground­wa­ter use sul­fur as an ener­gy source to chem­i­cal­ly change sul­fates to hydro­gen sul­fide. The bac­te­ria use sul­fur from decay­ing plants and oth­er organ­ic mat­ter in oxy­gen-defi­cient envi­ron­ments. They can occur in deep or shal­low wells, and reside in plumb­ing sys­tems. Hydro­gen sul­fide can reveal itself in oth­er ways too. Hot water heaters that have a mag­ne­sium rod used for cor­ro­sion con­trol can chem­i­cal­ly reduce sul­fates to hydro­gen sul­fide. Hydro­gen sul­fide also can enter sur­face water through springs as well.   It is most com­mon in shales and sand­stones. The occur­rence of hydro­gen sul­fide gas has been asso­ci­at­ed with ground­wa­ter with low pH and/or ground­wa­ter with high lev­els of iron and/or man­ganese (typ­i­cal water qual­i­ty issues in New Eng­land).  Hydro­gen sul­fide has a pun­gent smell at low con­cen­tra­tions and most peo­ple can detect con­cen­tra­tions above 0.03 ppm. There is no Max­i­mum Con­t­a­m­i­nant Lev­el estab­lished by the Unit­ed States EPA.

DOES HYDROGEN SULFIDE POSE A HEALTH RISK OR IS THE ROTTEN EGG SMELL JUST AN AESTHETIC ISSUE?

Usu­al­ly it is not a health risk at con­cen­tra­tions present in house­hold water.  How­ev­er, hydro­gen sul­fide gas is flam­ma­ble and poi­so­nous at high con­cen­tra­tions.  Buildup of hydro­gen sul­fide con­cen­tra­tions in con­fined areas has been known to cause adverse health effects.

Bac­te­ria in ground­wa­ter are respon­si­ble for most of the sul­fide smells detect­ed while sam­pling water wells. These are not often asso­ci­at­ed with high enough con­cen­tra­tions to be a health issue. In rare cas­es, sul­fide pres­ence may be due to sewage pol­lu­tion. If you expe­ri­ence a hydro­gen sul­fide odor sud­den­ly, con­sult with a water fil­tra­tion sys­tem pro­fes­sion­al.

OTHER AFFECTS — Hydro­gen sul­fide is cor­ro­sive and can leach met­als from plumb­ing sys­tems into the water. The result of this cor­ro­sion of met­als by hydro­gen sul­fide can be  a black pre­cip­i­tate that can stain laun­dry and bath­room fix­tures, dark­en sil­ver­ware, and dis­col­or cop­per and brass uten­sils.

HOW DO I GET RID OF THE ROTTEN EGG SMELL IN MY WATER?

While there are a num­ber of tech­nolo­gies avail­able to remove the rot­ten egg smell in your water, it can­not be viewed in a vac­u­um.  The pH lev­el, iron & man­ganese lev­els, as well as oth­er con­t­a­m­i­nants present in the water must be eval­u­at­ed for an effec­tive, com­pre­hen­sive solu­tion to this issue.  Some of the tech­nolo­gies and sys­tems that may be used include:

  • Ozone treat­ment cre­ates a chem­i­cal reac­tion that pre­cip­i­tates sul­fur. Ozone is effec­tive for con­cen­tra­tions up to 10 ppm.
  • Oxi­diz­ing fil­ters will work for con­cen­tra­tions up to 6 ppm. The fil­ter con­tains sand with a man­ganese diox­ide coat­ing that changes hydro­gen sul­fide gas to tiny par­ti­cles of sul­fur that are trapped inside the fil­ter.
  • Acti­vat­ed car­bon fil­ters can be effec­tive when hydro­gen sul­fide is present in low lev­els (up to about 0.3 ppm). The hydro­gen sul­fide is absorbed onto the sur­face of the car­bon par­ti­cles. Fil­ters require peri­od­ic replace­ment and can har­bor sul­fate-reduc­ing bac­te­ria
  • Shock chlo­ri­na­tion of your well may reduce the hydro­gen sul­fide-pro­duc­ing bac­te­ria. It’s most effec­tive in water with a pH between 5 and 7 and inef­fec­tive in alka­line (high­er pH) water.  An acti­vat­ed car­bon fil­ter may be nec­es­sary to remove resid­ual chlo­rine or small amounts of remain­ing hydro­gen sul­fide.
  • Oxi­da­tion removes hydro­gen sul­fide con­cen­tra­tions exceed­ing 6 ppm. It can be done by aer­a­tion, chlo­ri­na­tion, and potas­si­um per­man­ganate.
  • Water heater mod­i­fi­ca­tion is nec­es­sary when hydro­gen sul­fide is caus­ing an odor with­in the water heat­ing sys­tem. Replac­ing the mag­ne­sium cor­ro­sion con­trol rod with one made of alu­minum or oth­er met­als usu­al­ly improves the sit­u­a­tion, how­ev­er, you should check the manufacturer’s war­ran­ty on the water heater to make sure you aren’t void­ing the war­ran­ty.

OTHER WHOLE HOUSE WATER FILTRATION SYSTEMS

There are dif­fer­ent types and sizes of whole house water fil­tra­tion sys­tems avail­able to address the var­i­ous types of poten­tial water qual­i­ty issues expe­ri­enced in George­town. Select­ing the ones that address the water qual­i­ty issues that have been iden­ti­fied and that you are con­cerned with is the task at hand.  Not only is match­ing the right tech­nol­o­gy impor­tant, but also siz­ing the sys­tem to meet the water usage demands of your home is very impor­tant.  Last, but not least, a pro­fes­sion­al­ly plumbed sys­tem is also crit­i­cal as well as main­te­nance of the sys­tem through­out the years to opti­mize the use­ful life and prop­er func­tion­ing of your new equip­ment.

While symp­toms of water qual­i­ty issues such as bad odors & taste, stain­ing of laun­dry, bath­room fix­tures, etc. are indi­ca­tors of prob­lems, the pre­ferred start­ing point is to get a water test to iden­ti­fy the min­er­als or con­t­a­m­i­nants in the water and at what quan­ti­ty they exist.  This will lead to an effec­tive sys­tem rec­om­men­da­tion and route to pro­vid­ing your home with excel­lent water qual­i­ty.  While cer­tain min­er­als & con­t­a­m­i­nants can be test­ed on-site, health threat items like radon in water, arsenic in water, nitrates and oth­ers should be prop­er­ly sam­pled and brought to a cer­ti­fied lab­o­ra­to­ry for test­ing that requires spe­cial­ized equip­ment.

WATER SOFTENERS

Whole house water fil­tra­tion sys­tems

A water soft­en­er is a type of whole house water fil­tra­tion sys­tem that is designed for remov­ing hard water min­er­als (mag­ne­sium & cal­ci­um) as well as dis­solved iron and man­ganese from the water.  For water with high lev­els of iron or man­ganese (“the stain­ers”), a “down-flow” water soft­en­er is rec­om­mend­ed to pre­vent min­er­al build-up in the bot­tom of the water soft­en­er.  Also, high effi­cien­cy water soft­en­ers that are more effi­cient with both water and salt usage are pre­ferred.

WHOLE HOUSE WATER FILTRATION FOR OTHER CONTAMINANTS

Oth­er con­t­a­m­i­nants found in New Eng­land well water include Radon and Arsenic.  A water soft­en­er will not remove these health threat con­t­a­m­i­nants. Radon in water is safe­ly removed with an aer­a­tion sys­tem that agi­tates the incom­ing well water, releas­ing the gas from the water in a sealed cham­ber. This gas is then safe­ly vent­ed to the out­side ambi­ent air.

Arsenic in water can be removed at the point of entry into the home by installing tanks filled with arsenic spe­cif­ic resin that cap­tures the arsenic before it can get into the home’s water sup­ply.  Point of use sys­tems for drink­ing water can use reverse osmo­sis tech­nol­o­gy to effec­tive­ly remove arsenic as well. Speak to a water treat­ment pro­fes­sion­al to decide which sys­tem is right for you.
