If you live in an area with a lot of snakes, what you may be experiencing is a contamination of your water. Some snakes emit an onion-like odor when scared (like a skunk does). What makes this potentially dangerous is that you may also be ingesting their feces as well, which can contain Salmonella and/or tapeworm eggs. You definitely want to get this checked out by a professional.
The rotten egg smell is sulfur...
It has a high sulfur content to it.
The content of sulphur and other minerals in the geyser creates the bad smell.
Liquid chlorine oxidizes everything in water including sulfur dioxide. Sulfur dioxide has that rotten egg smell
It may or may not...if there is some acid in the solution, then sulfur is a byproduct of the equation, which will lead to a sulfur smell. However, I don't feel like it would cause the smell, without at least a catalytic amount of acid.
Onions contain sulfur compounds (which also give them their characteristic smell). The compounds are gases and are released when onions are cut. These gases react with the water in the tears in the eyes to form other acidic compounds which irritate the eye and cause crying.
If it is a "rotten egg" sulfur smell it is bacteria. Flush the hot water heater and turn up the heat to between 130 and 140 degrees F.
your either have a well system or your located near the coast somewhere there is a high sulfur contentAnsweris it only after hot water that you notice the smell? is there still the anode rod in the water heater?
high sulfar content
the sour smell to water is usually caused by overpurification such as sulfur and other chemicals added at the plant
A water filter system will remove the sulfur smell by reducing the hydrogen sulfide that causes it. There are 4 different types of water filters: distiller, reverse osmosis, backwash and activated carbon water filters.
