Does a Rotten Egg Smell Make Water Unsafe to Drink?

Posted by

The other day we heard from 'Thelma D' who asked, " Does a rotten egg smell in our water make it unsafe to drink?"

As a general rule, when water sample has a rotten egg smell to it the odor comes from dissolved  hydrogen sulfide gas... which aside from the fact it stinks quite badly, poses no real threat to human health unless allowed to build up to very high levels in confined spaces.  A less common source of rotten egg smell involves contamination/pollution of a water source by raw sewage so we suggest testing for coliform bacteria if water -- particularly well water -- suddenly develops a rotten egg smell.

Working on the assumption that sewage has not infiltrated the water source, a major source of dissolved hydrogen sulfide gas involves anaerobic bacteria that generate the gas through interaction with sulfur and various metals.  The reaction may occur naturally in the environment and in hot water heaters.

Can you test for hydrogen sulfide? Usually a person's nose will tell them all they need to know for presence/absence testing but when considering water treatment options one needs to know how much hydrogen sulfide their water contains so they do not purchase too large or small of a water treatment system.

Hydrogen Sulfide Confirmed... Now What?

Water testing has confirmed the presence of hydrogen sulfide in your water and now you want it gone.   To effectively reduce hydrogen sulfide concentrations in drinking water we suggest considering one of the Crystal Quest Iron and Hydrogen Sulfide Whole House Water Treatment Systems that make use of custom blended filtration media formulated from glauconite green sand that effectively removes iron, manganese and hydrogen sulfide (sulfur smell) rotten egg odor sometimes found in water.

The Crystal Quest Iron and Hydrogen Sulfide Whole House Water Treatment Systems come in several sizes depending upon the iron concentration in raw (source) water and the number of faucets, toilets, etc. in a home.

Water Metals Testing Bundle

Earlier this morning we heard from 'Ammani' who wrote, "Hello.  We live near a landfill used quite a long time ago by companies that now most have settled cases out of court for illegal dumping of chemicals and waste that supposedly contained metals.  Your heavy metals check reads total metals, correct?  But it does not [...]

Rainwater hits the ground and then passes across all sorts of different surfaces and carries with it any and all sorts of contaminants that it encounters. The list of contaminants may include byproducts from industry like chemicals and heavy metals as [...]

Why Do I Need to Use Hydrogen Peroxide in My Hot Tub?

Earlier today we heard from 'Vick' who asked, "We just got a hot tub and the salesman said to use a biguanide system that also uses hydrogen peroxide.  Why do we need to use two chemicals?  Why doesn't the biguanide stuff do the job all on its own?  So we HAVE to use the peroxide [...]

Are Municipal/City Water Sources Immune to Pesticide Contamination?

This morning 'Traycee' asked, " If our water comes from a city water system we don't have to worry about pesticide contamination, right?" Thank you for the inquiry, Traycee.  As a general rule city and municipal water supplies SHOULD not have pesticides as contaminants, but before you can fully rule that possibility out, please remember the following: Public [...]

Testing for MTBE

Recently we heard from someone in Arizona who asked, "do you test water from out of state,Arizona? Wanted to make sure kit tests for MTBE? We are on city water in Arizona, just want to make sure....thank you. Please email back." Although we do not personally perform any testing, several of the mail-in test kits we [...]

Does the WaterSafe City or Well Water Test Kit Detect MTBE?

Earlier today we received an inquiry from 'FloydG' who asked, " I was looking at the WaterSafe city and well test kits and need to know if one of them or both of them can test for MTBE.  Thanks." MTBE gets categorized as a volatile organic compound (VOC) and as such cannot get detected by do-it-yourself home [...]
