3 beaches of the San Mateo district among the most polluted in California – the NBC Bay area

Erckenbrack Park, Marlin Park and Lakeshore Park in San Mateo County are on Heal the Bay’s “Beach Bummer List” 2021-2022 because they are among the most polluted beaches in California.

San Mateo County is reportedly home to more “beach loungers” than any other district in recent years. Erckenbrack Park is on the list for the third year in a row, while Marlin Park is on the list for the second year in a row.

Lakeshore Park has been on the list five times in the last 10 years.

According to the report, these beaches in San Francisco Bay are enclosed in an artificial tangle of canals that do not allow easy water circulation. The canals also won the city a decisive match from the surrounding residential and commercial buildings.

Santa Monica-based Heal the Bay is a non-profit organization dedicated to protecting California’s coastal waters and watersheds. Heal the Bay issued its annual Beach Report Card on Wednesday, which assigns letters from A to F 500 to California beaches.

The levels are based on the level of faecal indicator bacterial contamination in the ocean measured by district health agencies. Fecal indicator bacteria, such as E. coli, live in the intestines of warm-blooded animals and enter the environment through the faeces.

Most organizations that study ocean pollution are concerned about fecal pollution from other contaminants, such as metals, because fecal pollution poses an acute health risk, which means that one exposure can cause disease. In contrast, metals pose a chronic health risk, which means that the disease is the result of long-term exposure to a contaminant.

Other beaches on the “Unlucky List” include Santa Monica Pier and Marina del Rey’s Mother’s Beach in Los Angeles County, Newport Bay in Orange County, Tijuana Slough in San Diego County and Moonstone County Park in Humboldt County. Heal the Bay, which is considered Playa Blanca near Tijuana, monitored by San Diego County, is the number one beach this year.

A total of 94 percent of California beaches rated Heal the Bay received an A or B grade in the summer of 2021, the same level as the five-year average. However, the report warned that polluted water poses a significant health risk to millions of California residents. People who come in contact with grade C or lower water are at greater risk of stomach flu, ear infections, upper respiratory tract infections and rashes.

“A day at the beach and on the river shouldn’t make anyone sick,” said Tracy Quinn, president and CEO of Heal the Bay.

“The great news is that most beaches in California have good bathing water quality. But there are areas of poor water quality that need to be improved and infrastructure upgraded. We must not forget that our marine ecosystems are still threatened by the climate crisis and other sources of pollution and we need We expect people to seek more and more ocean shores and freshwater baths to cool off with rising temperatures, so safe, clean and healthy water is now needed more than ever. ”

Rain usually increases the number of pollutants on beaches and rivers, and the report found that only 66 percent of California beaches had good or excellent ratings in wet weather, which was slightly above average but “still very worrying.” Last year, rainfall in California’s coastal region was 24 percent lower than the historical average.

Overall, only 68 percent of San Mateo County beaches received A or B during dry summer weather, 44 percent received A and B during wet weather, and 78 percent received A and B during dry winter weather.

According to the report, there were 38 effluents in San Mateo County last year in San Mateo County, adding up to 3,950,039 gallons of wastewater to the water pollution.

All beaches in Alameda County and Contra Costa County received A or B during the summer dry weather, giving East Bay “excellent water quality.” However, during humid weather, only 13 percent of beaches received A and B ratings, which is much lower than the historical average of 64 percent.

All beaches in San Francisco received an A or B rating during the dry summer months, which is “exceptional and above average” according to the report. However, the wet weather grades were “woefully poor,” with 0 percent of San Francisco beaches receiving A grades and only 17 percent receiving B.

The beaches of the Mendocino district have all A during dry and humid weather. The beaches in Mendocino have not received a grade lower than B in the last five years.
