L.A. County Beaches Report Card: Interactive Map

The following is a water quality report from Oct. 14 to Nov. 14 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.

Please note: The last sampling date was Wednesday, therefore beach grades do not reflect the rain that hit the L.A. area on Thursday and Friday. So conditions may be worse than noted.

Dark Blue Marker = A+

Light Blue Marker = A

Green Marker = B

Yellow Marker = C

Pink = D

Red Marker = F
