Linda Mar Beach Health Impacts Survey
Help clean the water!
Over the past two years our testing has found:
-
85% of samples along the San Pedro Creek exceeded state safety standards for fecal indicator bacteria
-
DNA testing has identified human fecal contamination. Leaking sewer infrastructure is the suspected source.
-
Ocean water north of Taco Bell is mostly safe except during heavy rains or rare pumping station discharges
We need your help to understand how these water quality issues affect people. This survey will take less than 3 minutes. Your responses will help:
-
Document health impacts on swimmers, surfers, and beachgoers
-
Inform public agencies and elected officials
-
Advocate for infrastructure improvements
Every response strengthens the evidence needed to protect public health and improve water quality at Linda Mar Beach and San Pedro Creek. Thanks for being part of the solution!


The Linda Mar Water Quality Coalition includes Surfrider San Mateo, Salted Roots, San Pedro Creek Watershed Coalition (SPCWC), Cultivar Foundation and the Pedro Point Surf Club. We test the mouth of San Pedro Creek at Linda Mar Beach and upstream on the creek for fecal bacteria every week.
Beach Bummer!!
Linda Mar Beach is one of the most popular surfing beaches in the Bay Area, yet every year is listed as one of the most polluted in California. The beach routinely fails to meet state and federal standards for fecal bacteria in recreational waters. This is due to San Pedro Creek, which acts as a storm sewer for the Linda Mar section of Pacifica.
Safer Surfing & Recreation
-
Surf away from the mouth of the creek. From the Taco Bell north is usually safe except after storms.

Please don't let your kids play in the creek!
