Feds confirm exposure to some levels of Tijuana River odors can lead to health effects (opens the original)
Read excerpt
Exposures to some levels of hydrogen sulfide in outdoor air near the sewage-laced Tijuana River are a public health hazard, according to a new report by the Agency for Toxic Substances and Disease Registry (ATSDR). In a 72-page report released Wednesday, the agency concluded that short-term exposure to the sewer gas can lead to health effects such as headaches, cough, nausea and shortness of breath. But longer-term exposures, defined as two weeks or more, and chronic exposures, or at least one y
‘It must be the Imperial Valley’s moment:’ A renewed commitment for the decades-long New River crisis (opens the original)
Read excerpt
A year ago, Lee Zeldin, head of the U.S. Environmental Protection Agency (EPA), visited the Tijuana River, one of the nation's most polluted rivers, and vowed to act urgently to stop the crisis.

It’s called La Semilla Community Resiliency Center, a multiuse community center built on what was once a 7,000-square-foot vacant lot on Park Avenue near Hall Avenue. Officials celebrated its opening Thursday with a ribbon-cutting ceremony. Residents can cool down during heat waves, charge their devices during power outages and gather during other climate hazards. Lisa Cuestas, CEO of Casa Familiar,
San Diego County to explore treating Tijuana River sewage flows (opens the original)
Read excerpt
San Diego County could start treating sewage that spills into the binational Tijuana River from Mexico, reforming how the region manages the decades-long pollution crisis. In a 4-1 vote Tuesday, the county Board of Supervisors approved a multistep plan to explore building infrastructure that would treat flows in the river before they enter the ocean. The South Bay International Wastewater Treatment Plant, which the U.S. operates, and other treatment infrastructure Mexico manages, are meant to ke
