Porter ranch homes to be tested for gas-leak chemicals

Los Angeles County health officials will begin air and surface tests inside 100 Porter Ranch homes on Friday to look for chemicals left over from the natural gas leak that spewed tens of thousands of metric tons of methane over neighborhoods for almost four months.

“We will be looking at a variety of chemicals in the indoor environment,” said Angelo Bellomo, deputy director for health protection at the Los Angeles County Department of Public Health.

Bellomo said the department is working with the U.S. 3 main gas laws Environmental Protection Agency and professor Michael Jerrett, chairman of environmental health sciences at the UCLA Fielding School of Public Health. Electricity how it works Jerrett began collecting outdoor air quality samples throughout the Porter Ranch community early on during the gas leak, including indoor dust swab sampling at seven homes.

Benzene and hexane were found in two of the homes, health officials said. K electric company They said it is unknown if the levels found are high enough to have toxic effects on humans.

During a press conference Wednesday, Dr. Bad gas 6 weeks pregnant Jeffrey Gunzenhauser, interim director for the Department of Public Health, said it’s too early to know what the findings mean.

But Jerrett’s preliminary analysis of outdoor air near the gas leak showed “higher and more variable concentrations of particulate matter in the outdoor air at locations close to the leak site” compared with locations farther away, according to the Health Department. 76 gas station jobs Particulate matter is described as tiny pieces of solids or liquids in the air, such as dust, dirt, soot or drops that can irritate the skin, eyes, nose, throat, and respiratory and cardiovascular systems.

Teams from the Department of Public Health will use standard air-collection sampling techniques but also do swipe sampling to pick up fine particulate matter on surfaces, he added.

The goal is to collect samples and test them, then compare the findings to results from samples taken from homes in a control group in nearby Northridge.

The county’s plan to conduct indoor testing is considered a major victory for Porter Ranch and the surrounding community, said Alexandra Nagy, senior organizer for Food & Water Watch, which has helped residents organize.

“It is a testament to the persistence of the affected residents who are fighting to protect their families by holding public agencies accountable for the community’s health,” Nagy said in a statement.

Attorney R. Gas hydrates are used Rex Parris, who has filed a lawsuit on behalf of residents, said at the press conference that Southern California Gas Co., which operates the wells, should pay to do deep indoor cleaning of all homes, including vents.

“The Merry Maids aren’t capable of cleaning them,” he said, referring to the housekeeping service. Gas prices going up to 5 dollars “The catastrophe of this cannot be overstated.”

“SoCalGas continues to provide home cleaning assessments for brown spots or other potential impacts that could be associated with the leak,” the statement said. Electricity lesson plans year 6 “To date, we have not found any evidence of spots or impacts indoors.”
