Rotten Eggs The smell of rotten eggs is instantly recognizable and can be an indicator of a serious problem in your home.

The two most common sources of a rotten egg smell are a natural gas leak , and escaping sewer gas. If there's a very strong smell, you could have a substantial natural gas leak.

The rather stale, sulphury smell is dimethyl sulphide, produced by bacteria as they digest dead phytoplankton. At low tide, you'll also smell chemicals called dictyopterenes , which are sex pheromones produced by seaweed eggs to attract the sperm.

The sulfur binds with oxygen to form the compound sulfate. Sulfur compounds are naturally occurring in hot springs and the source of the characteristic eggy odor. It's interesting to note that the deeper the hot springs and the faster it sends water to the surface, the stronger the smell. Smelling hydrogen sulfide does not mean that it will harm your health. The smell can cause worry, anxiety and resentment. Repeated odour events may culminate in real symptoms such as headache, fatigue and nausea.

Not all hot springs have it to the same extent, there are some that don't have the hot springs smell at all.

This was was a decrease of 1. Foster City, California, was created in the s on former tidal marshland near San Mateo, overlaid with an engineered landfill of sand and shell dredged from San Francisco Bay. Foster City was founded in the s, built on the existing Brewer Island in the marshes of the San Francisco Bay on the east edge of San Mateo, enlarged with engineered landfill.

Milpitas home prices are not only among the most expensive in California, but Milpitas real estate also consistently ranks among the most expensive in America. There are two sources of this rotten egg odor. Another is an old sewer line built in that emits high levels of smelly hydrogen sulfide near the San Jose airport. A new sewer line has largely been completed and should make the smell lessen.

San Francisco has many lovely qualities, but huge swaths of the city smell like pee. The typical daily urine dose of most cities really accumulates. Some people think this has to do with a lack of rain, either in general or recently. What is the smell? Hydrogen sulfide is found in oil fields and other petroleum operations, and can arise from rotting organic matter including seaweed, algae blooms and dead fish.

Normally, the wind is from the northwest which means the odors tend to go south of Fremont. The winter is when we see more southwesterly winds which are the worst in this regard. The strong odor which ponds often produce are the result of high concentrations of decaying organic matter.

This is a natural process that produces nutrients used in the food chain. The bridge has never been officially named, but its commonly used name comes from Dumbarton Point, named in after Dumbarton, Scotland.

If folks were stupid enough to build their million dollar homes there, then it is their fault they smell the smell, not an on going business. And there are other ways you can drive across the lower bay than going by the bridge you now use. Why should the company be forced to give up their business, when they were there first.

I've only been over this bridge for 2 round trips and not only was the smell appalling, it was strong enough that I got angry about it.

I developed a sensitivity to odors back to when I worked for a garbage company back in the early 70's. In May of this year, I got sprayed by a skunk.

Yes, the smell was strong and even made me cough but the odor was far preferable to what I smelled going over the bridge. I might have to cross the bridge again in about a week and you can laugh if you like but I'm bringing my respirator that has 2 filters on it that I got a while back at a home center. I'm glad I've seen some explanation here for the foul odor. Please register to post and access all features of our very popular forum.
