The Chiquita Canyon Landfill has landed in hot water with California authorities after a Proposition 65 Notice, issued by the California Department of Toxic Substances Control, revealed a threat of illegal hazardous waste discharges, according to official documents. The concerning substances were noted to include benzene, a known carcinogen, raising significant environmental and public health concerns.
Following the scent of malpractice, in November 2023, the Department of Public Health's Solid Waste Management Program, caught Chiquita Canyon Landfill not complying with crucial leachate control requirements. The Landfill was handed a notice of violations and a direct order to rectify their handling of a thermal reaction causing excessive leachate. They were instructed to upgrade their drainage system to prevent potential failures and to perform tests on the leachate for, volatile organic compounds like benzene.
Adding to the landfill's woes, the Los Angeles Regional Water Quality Control Board stepped in with a Notice of Violation on November 22, noting the operator, Waste Connections, had bungled leachate containment and proper reporting. The Board has been working closely with local and federal agencies, conducting ongoing inspections to confirm whether there has been any discharge of contaminated stormwater.
In December, the noose tightened as DTSC's tests confirmed that the leachate was more than just dirty water; some samples were indeed tipping the scales past hazardous waste limits for benzene. On February 15, DTSC slapped the Landfill with a Summary of Violations, calling them out for their mismanagement and insufficient categorization of waste, essentially treating a toxic soup like regular garbage, and risking hazardous leaks.
The foul brew of leachate at the Landfill, now officially branded hazardous, must be dealt with using stringent disposal measures. Plus, given the ongoing chemical reaction dilemma, on-site treatment of leachate before disposal has become an immediate, non-negotiable remedy. This critical operation falls under the watchful eye of the Multi-Agency Critical Action Team, which is a coalition of local, state, and federal agencies tasked with keeping a close watch over the landfill's cleanup act.
