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

Ride-hailing company Uber is offering people free and discounted rides if they need a lift to and from a COVID-19 vaccination appointment.In a press release, CEO Dara Khosrowshahi said the company offers 10 million free or discounted rides to ensure people get vaccinated, especially those who face a barrier getting there.Khosrowshahi said they are partnering with the National Urban League, the Morehouse School of Medicine, and the National Action Network because the organizations are tied to communities of color that have been "disproportionately hurt by the pandemic."A date when this is to kickoff has not been announced. 637

SACRAMENTO, Calif. (AP) — The number of reported hate crimes and victims decreased last year in California, although the number of suspects increased, the state's attorney general reported Tuesday.Hate crime events fell 2.5% from 2017, down by about two-dozen reports to 1,066 in 2018, according to the annual report.That follows a 17% jump the prior year.The state defines hate crimes as those targeting victims because of their race or ethnicity, nationality, religion, sexual orientation, gender or a disability. The definitions have been expanded at various times in recent years. Each hate crime event can include more than one related offense against more than one victim by more than one offender.The report notes that hate crimes remain relatively rare in a state of nearly 40 million people. Overall, they have dropped about 3% in the last decade.There were 80 more suspects identified last year than the year before.The report comes a year after Attorney General Xavier Becerra provided more guidance for local law enforcement and created a hate crimes prevention webpage and brochure on identifying and reporting hate crimes. The increased outreach came after a critical state audit largely blamed the department for not requiring that local agencies do a better job in collecting data, resulting in undercounts.Anti-Islamic events dropped from 46 in 2017 to 28 last year, the new report says. But those targeting Jews increased from 104 to 126 last year.Earlier this year, authorities said a 19-year-old gunman told investigators he was motivated by hatred for Judaism when he killed one woman and wounded two others, including a rabbi, at the Chabad of Poway synagogue near San Diego. That shooting in April will be reflected in next year's report.There were no hate-related murders reported in 2018, but one rape, 39 robberies and nearly 800 reports of assaults and intimidation. Yet violent and property offenses related to hate crimes both dipped, with 838 violent and 426 property crimes reported last year. That was down from 860 violent and 451 property crimes a year earlier.Hate crimes based on race or sexual orientation both fell overall. But crimes against Latinos were up from 126 in 2017 to 149 last year, while those against blacks dropped from 302 to 276.There were 238 reports of hate crimes based on sexual orientation, down eight from the prior year.Federal authorities have estimated that more than half of all hate crimes aren't reported to police across the United States.The Associated Press found three years ago that more than 2,700 city police and county sheriff's departments nationwide had not reported any hate crimes for the FBI's annual crime tally during the previous six years, or about 17% of all city and county law enforcement agencies. 2792
