SACRAMENTO, Calif. (AP) — Chemicals used for carpets and anti-stain products have been found in water sources for 7.5 million people in California, detailing the extent of the problem as state regulators work to develop safety levels for the contaminants that have been linked to cancer.A report released Wednesday by the Environmental Working Group found variants of the chemicals known as PFAS in 74 community water systems between 2013 and 2019, according to data from state and federal regulators. More than 40 percent of the systems had at least one sample that exceeded the health advisory level set by the U.S. Environmental Protection Agency.Communities served by systems with the highest detections of PFAS include Corona, Camp Pendleton, Oroville, Rosemont and areas of Sacramento.PFAS chemicals are used to make products water and stain resistant, including carpets, clothing, furniture and cookware. Two of the most well-known chemicals, PFOS and PFOA, have been phased out in the United States. But they don't break down easily and linger in the environment, earning the nickname "forever chemicals."RELATED: EPA: California homelessness causing poor water qualityStudies have linked PFOS and PFOA to a variety of health problems, including cancer, immune system issues and liver and thyroid problems. But there are thousands of variants of PFAS chemicals."One of the biggest takeaways here is we're not just detecting just PFOA and PFOS in these systems, but it's a mixture of different PFAS chemicals," said Tasha Stoiber, a senior scientist at the Environmental Working Group.California does not set maximum contaminant levels for PFAS chemicals or require water agencies to test for them. It does encourage water systems to test for them and offers guidelines on when they should notify the public. If agencies do test, they must report any samples that exceed the guidelines.RELATED: San Diego leaders present 0 million plan to solve Mexican sewage problemEarlier this year, Democratic Gov. Gavin Newsom signed a law allowing state water regulators to order more systems to monitor for PFAS chemicals and to notify the public. The law takes effect Jan. 1.Meanwhile, the State Water Resources Control Board is developing maximum contaminant levels for PFOS and PFOA. But those are just two of the thousands of variants of PFAS chemicals. Andria Ventura, toxic program manager at the advocacy group Clean Water Action, said setting standards for only two of the chemicals "sends the wrong message to the public."Ventura said she knows it is difficult to regulate for a class of chemicals this large, but "we need to start investigating how to do that, or how to at least get bigger chunks of these chemicals regulated."RELATED: San Diego Surfriders send 2,200 letters calling for Tijuana River clean-upWater systems have responded to the PFAS problem by taking wells offline, blending the contaminated water with cleaner sources and installing treatment systems.One of the highest concentrations of PFAS chemicals was found earlier this year in a well run by the California Water Service Company in Oroville. For every trillion parts of water, the sample contained 451 parts of six PFAS chemicals. That's more than six times higher than the EPA guidelines.Spokeswoman Yvonne Kingman said the company does not use the well to supply drinking water to its customers, but the company keeps the well online in case it needs the well for firefighters or as a backup should the main plant go offline. Kingman said the company tests for 14 types of PFAS chemicals.RELATED: EPA set to end California's ability to regulate fuel economy"The protection of our customers' health and safety is our absolute highest priority, so we've been monitoring this for quite a while," Kingman said.PFAS chemicals have been a problem near military bases because it is an ingredient in a foam the military uses to fight liquid fuel fires. A 2017 sample at a well in Camp Pendleton, the Marine Corps base in San Diego, contained seven PFAS chemicals for a combined 820 parts per trillion, or 11 times higher than the EPA guidelines.Camp Pendleton officials stopped using that well after the test, spokesman Capt. David Mancilla said. The base only uses the foam for emergencies, he said."The drinking water at MCB Camp Pendleton is safe to drink and meets or exceeds all regulated standards," he said. 4402

SACRAMENTO, Calif. (AP) — The western Joshua tree will be considered for protection under the California Endangered Species Act because of threats from climate change and habitat destruction. The state Fish and Game Commission on Tuesday voted to accept a petition that provides the yucca plants protected status for a year while the agency conducts a study. After the review, commissioners will determine whether the species should be formally protected under the law. The petition by the Center for Biological Diversity came amid rising concern about the future of the crazy-limbed trees with spiky leaves that have come to symbolize the Mojave Desert and draw throngs to Joshua Tree National Park. 708

Rioters torched a Georgia Tech police car Monday night as students protested the death of 21-year-old Scout Schultz, who was shot and killed by a Georgia Tech police officer Saturday night.After a vigil for Schultz Monday evening, a smaller group of about 50 protesters marched to the Georgia Tech Police Department. Two officers were injured during the unrest.The incident promoted Georgia Tech to issue an alert, advising students to stay indoors.Georgia Tech police officers approached Schultz Saturday night after responding to a 911 call that the Georgia Bureau of Investigation later learned came from Schultz.According to the GBI, Officer Tyler Beck shot Schultz after the student refused to comply with police commands to drop a weapon.Investigators said they found three suicide notes located in Schultz's dorm room.Schultz's parents talked with reporters Monday, demanding answers over the death of their child.Georgia Tech says the Atlanta Police Department and Georgia State University Police Department helped to restore order after the Monday night incident. Vincent Castillenti, Jacob Wilson and Cassandra Monden were all arrested and charged with inciting a riot and battery of an officer, according to the school.Schultz' parents issued the following statement on behalf of their attorney after the incident: 'On behalf of the family of Scout Schultz, we ask that those who wish to protest Scout's death do so peacefully. Answering violence with violence is not the answer. Our goal is to work diligently to make positive change at Georgia Tech in an effort to ensure a safer campus for all students.This is how we will truly honor Scout's life and legacy.Scout's family respects the rights of those who wish to voice opposition to what they feel was an unnecessary use of force, but they ask that it be done respectfully and safely."Georgia Tech President G.P. "Bud" Peterson sent the following letter to the Georgia Tech community on Tuesday morning: 1977
