UPDATE: Elevated levels of the toxic metal hexavalent chromium have been detected near two factories in Paramount, California, prompting urgent air quality violations. The South Coast Air Quality Management District (SCAQMD) announced findings from air samples collected between September 10-22, 2023, revealing “slightly elevated” levels of this potent carcinogen.
This alarming discovery comes as federal and state regulators emphasize that there is no safe level of exposure to hexavalent chromium, which poses serious health risks, including cancer. Recent samples taken from a monitoring station near Minnesota Avenue and Madison Street showed concentrations ranging from 1.6 to 2.2 nanograms per cubic meter, significantly raising concerns about public safety.
In response to these findings, the SCAQMD has taken decisive action, issuing multiple violations to Pro Cast Industries, located directly across from the monitoring station, and Fenico, approximately 1,300 feet east. Investigators allege that both facilities failed to conduct necessary tests to comply with emission limits, did not adequately clean areas around chrome-alloy-melting operations, and operated without essential permits.
Hexavalent chromium is notorious for its carcinogenic properties—being 500 times more carcinogenic than diesel exhaust—and it ranks as the second-highest cancer risk among toxic air contaminants tracked by the California Air Resources Board. Exposure to just 1 nanogram per cubic meter over three decades is linked to 360 cancer cases per 1 million people, according to state reports.
Mayor Peggy Lemons stated, “We’re working diligently to ensure the air in our city remains safe for all our residents. The South Coast AQMD has the expertise and enforcement tools to investigate and address these readings.” She reassured the community of the city’s commitment to transparency and public health.
Historically, Paramount is home to numerous metal-related businesses, contributing to some of the highest concentrations of hexavalent chromium in California. Notably, a spike of 26 nanograms per cubic meter was recorded in October 2016. In response to past concerns, the SCAQMD launched a community air monitoring network in 2013, which had previously revealed toxic metal levels in parts of Paramount that were over 50 times higher than other areas in Los Angeles County.
Despite reductions in toxic metal levels through investigations and inspections, recent air sampling indicates persistent challenges with compliance, likely exacerbated by equipment malfunctions and inadequate regulatory adherence. The SCAQMD is exploring potential settlements with the two foundries, but warns that financial penalties may be imposed if an agreement is not reached.
As this situation develops, residents and local businesses are urged to remain vigilant. The community’s health and safety are at stake, and ongoing monitoring efforts will be crucial in the fight against air pollution. Stay tuned for updates as this story unfolds.
