L.A. County Beaches Report Card: Interactive Map

How did your favorite beach score?

The following is a water quality report from Sept. 22 to Oct. 22 compiled from data courtesy of Heal the Bay, a nonprofit environmental group.

Grades are based on an A+ to F scale. Grades indicate the likelihood of swimmers becoming ill. Water samples are analyzed for bacteria – enterococcus, total and fecal coliforms. The report does not measure the amount of trash or toxins found at local beaches.

Dark Blue Marker = A+

Light Blue Marker = A

Green Marker = B

Yellow Marker = C

Pink = D

Red Marker = F

Purple Marker = No sample taken

I wonder why no sample taken at Will Rogers State Beach at Santa Monica Canyon drain (Chautauqua)??????

Hi Lisa, That was a mistake. It was a actually a B grade.

David Carini - Can you explain why your label for Surfrider is "Surfrider Beach (breach location) daily" yet the report clearly states that the testing was last done on Oct 4th? The water quality testing was to be performed daily, yet this report appears to be providing information that the testing requirement is not being adhered to? What type of testing was done at that specific location, the new isometric dna method or still employing the old test methods? If using the old, why and when can we expect to see a shift to the newest scientific methods for improved public safety information campaigns?

Hi M Stanley, I spoke to a person at Heal the Bay who puts together the beach scores. He said "The 'daily' label is sort of a legacy header that means that the location is sampled more than once per week. (surfrider is sampled about 5 times per week). Sampling methods are still the 'old' 18-24 hour culture methods. Rapid methods are being developed and may be recommended by the US EPA in their new beach monitoring criteria (being released next month), but as of now there is nothing in the new criteria to mandate a move to the newer rapid methods.
