LA County issues pollution warning for water around busy Santa Monica Pier
L.A. County officials have issued an advisory warning people not to swim, surf, or play in the water 100 yards on either side of Santa Monica Pier due to high levels of bacteria.
Public health officials warn that people who swim in water with these contaminants could develop rashes, ear and upper respiratory infections and stomach bugs.
Heal the Bay, which issues a weekly beach pollution report card based on its own testing, says the area is a repeat offender.
“From a scale of A-plus to F, in 2025 the Santa Monica Pier has gotten only Fs,” said Naomi Meurice, a water quality data analyst at Heal the Bay.
The good news is that water quality about 100 yards on either side of the Santa Monica Pier is much better.
An important question about the pollution remains unanswered: where is the bacteria coming from?
“ I wish I knew the answer and I wish I could tell you, but unfortunately, it's not super clear to us what exactly is causing all of this pollution,” Meurice said.
She noted that the results show it’s mostly fecal matter, but it’s not known if it’s from people or animals.
Meurice said a task force formed by Santa Monica and Heal the Bay in the next few months will start working to find an answer.
