Title Mystery Odor Causes Several Hundred Emergency Calls in Southern California
Introduction LA Testing provides odor identification services to help identify and resolve mystery odor complaints.

Cinnaminson, NJ, September 13th, 2012

Earlier this week, Los Angeles’ KTLA reported that the Los Angeles Fire Department had received hundreds of phone calls regarding a disturbing mystery odor.  According to the report, “KTLA viewers reported the stench over a wide area -- from Fontana, Redlands and Hesperia to the north San Fernando Valley to Valencia.”

The odor was described as smelling like a mixture of rotten eggs and sulfur.  A spokesperson for the California Department of Forestry and Fire Protection stated that the odor is most likely coming from the Salton Sea and that similar incidents have occurred in the past.

Mystery odors occur on a regular basis across the country.  They can be caused by a wide range of reasons that can occur both from within a building or infiltrate a structure from an outside source as appears to be the case with the recent foul odors in Southern California. 

These mystery odors are at times easy for professionals to identify.  Other times they can be a real challenge, requiring air sampling to help pinpoint the makeup of the odor and to eventually locate the source of the odor. 

One of the nation’s foremost testing laboratories for analyzing mystery odor samples is EMSL Analytical, Inc.  “At EMSL and our sister laboratory network in California, LA Testing, we have access to the latest field sampling equipment, laboratory testing equipment and world renowned scientists,” reported Joe Frasca, Senior Vice President, Marketing at EMSL Analytical and LA Testing.  “Mystery odors can simply be a nuisance, but at other times they can signal a health risk to people.  Air sampling during an occurrence can identify the culprit so that their can be a resolution of the problem,” he continued.

LA Testing recently sponsored an educational video about mystery odors that can be seen at:
