Borrego Sun - Since 1949

The South Coast Air Quality Management District has issued an odor advisory due to elevated levels hydrogen sulfide from the Salton Sea.

Hourly average concentrations of hydrogen sulfide (H2S) peaked in the evening of September 5 at 45 parts per billion immediately downwind of the Salton Sea. The monitor in Mecca, a more populated community further downwind, remained below 30 parts per billion. If southeasterly winds continue, additional areas may also experience the odors. Since a similar weather pattern is expected to continue, there may be periodic episodes with elevated concentrations of hydrogen sulfide.
