Iconic San Diego beaches that sit close to Tijuana closed over dangerous levels of SEWAGE in its waters https://t.co/VAs7ssfOnm

The beaches impacted by high bacteria levels extend two miles from the US-Mexico border. The entire shoreline in the Imperial Beach neighborhood has been closed.
The Environmental Health and Quality Department lifted the closure for Avenida Lunar Beach in the Coronado neighborhood on Monday.
Beaches near the southern border are frequently closed due to cross-border flows and degradation of the Tijuana River Estuary.
From October 2023 to May of last year, the San Diego Coastkeeper estimated 31 billion gallons of raw sewage, polluted water and trash had flowed down the Tijuana River into the Tijuana River Valley and the Pacific Ocean.
Sewage intefrastructure in Tijuana is outdated and not designed to withstand the city’s rapid population growth, so it often spills into nearby bodies of water during the rainy season.
