Residents Complain San Diego Drinking Water Is ‘Stinky’ and ‘Smells Like Mold’

Earthy, musty smelling water coming out of faucets in some San Diego neighborhoods will be around for a couple more days — but city officials say it presents no safety issues.

Officials said the odd smell of the water comes from a naturally occurring organic compound called 2-methylisoborneol, or MIB — caused by algae blooms in reservoirs that tend to happen during hot weather.
