HOW THE RESIDENTS
As a local state of emergency rolled-on, over 15,000 residents were displaced with many complaining of headaches, nausea, and severe nosebleeds caused by a high concentration of methane. Understandably, the gas leak also provoked great concern among school officials as numerous schools were located within the vicinity of the leak.
To address some of this concern, the school district and the owner of the gas well, the Southern California Gas Company, placed medical-grade HEPA air filters in every classroom, office and common area in all schools within eight kilometres of the leak. These actions provided a unique opportunity to assess and research the benefits of air filtration for students, teachers and school officials.
