Long Beach’s dirty ocean water at Coronado Avenue, north of Belmont Pier, makes in one of the 10 worst beaches in the state, according the 2018-2019 Beach Report Card released Wednesday by Heal the Bay. It’s the first time the beach has made the group’s “Beach Bummer” list. On the bright side, the report singled out the city’s long-term project to restore Colorado Lagoon North, a “chronic Beach Bummer” — on the 10 worst list until 2012 — but dramatically improving in water quality thanks to the work. Throughout Southern California, 95% of beaches received an “A” or a “B” for water quality in the summer. Of 33 Honor Roll beaches with perfect grades, two were in Los Angeles County and 10 were in Orange County. None were in Long Beach.
