SoCalGas to Conduct Indoor Air Screening


LOS ANGELES, CA – According to a news release, Southern California Gas Company (SoCalGas) will offer indoor air screening to a sampling of households near the Aliso Canyon gas storage facility in response to questions from some residents about indoor air quality in the Porter Ranch area.

The indoor air screening will seek to detect any level of methane or mercaptan that is higher than what would typically be expected inside a home.

The test, which will be conducted by an independent firm and results will be shared with the L.A. County Department of Public Health, will seek to detect any level of methane or mercaptan that is higher than what would typically be expected inside a home.

SoCalGas will invite 75 randomly selected residents in the Porter Ranch community to participate in the indoor air screening.

The screening will utilize a flame ionization detector to evaluate any detectable levels of methane, and Tedlar bags to capture indoor air “grab samples.”

Methane is the primary constituent and best indicator of any natural gas present in an environment. The company will also be testing for any presence of mercaptan, the odorant that is injected into natural gas as a safety measure. Mercaptan is what gives methane its sulfur smell.

The screenings will be conducted in each accessible room of the house, and results will be provided to residents within one week of the screening.

Screenings are scheduled to begin on Monday, March 14.

SUN News readers are invited to comment on the results of these screenings.
