Spokesman Sam Atwood told The Desert Sun ( http://mydesert.co/Wj7b12) monitoring levels of hydrogen sulfide in the area could help officials establish an action plan and notify the public of pending odor problems in the future.
Officials received more than 235 complaints of a foul, powerful odor after a thunderstorm Sept. 9 churned up the lower sulfurous water layers. The smell was detected across Southern California and in Arizona.
Environmental groups urged further action to mitigate the odors, saying federal air quality standards weren't being met in nearby rural communities.
