The South Coast Air Quality Management District today released the following statement:
Air Quality Officials Investigating Widespread Sulfur OdorsField inspectors with the South Coast Air Quality Management District are in the field today
investigating possible causes of widespread sulfur odors.
Since around midnight last night, AQMD has received more than 100 calls reporting a strong,
foul rotten egg/sulfur odor. Residents have complained from a very wide area including the
Inland Empire and much of the Los Angeles Basin.
Fish kills, algae blooms and other biologic conditions in lakes can cause strong odors.
Industrial facilities such as wastewater plants also can cause sulfur odors. At this time SCAQMD
hasn’t confirmed any source as the cause of the widespread odor.
SCAQMD will issue updated information later in the day if more information is available.
SCAQMD is the air pollution control agency for Orange County and major portions of Los Angeles,
San Bernardino and Riverside counties
