fecal

Contamination by bacteria from fecal matter has been found on several occasions in the wells supplying Perrier, especially after heavy rainfall.

The team analyzed fecal samples from 14 people with CAD and compared them to samples from 28 healthy participants using metagenomic sequencing, a powerful technique that identifies all the DNA within a sample.

Santa Monica Pier routinely tops the yearly list of the state’s dirtiest beaches by environmental nonprofit Heal the Bay, which tests waters up and down the California coast for fecal bacteria, which can harm beachgoers.

Some encampments are strewn with debris that spills across an entire walkway or out into the street, while others carry the smell of urine, fecal matter or decaying food waste.

Heal the Bay monitors beaches along the California coast — testing water samples for fecal bacteria, including coliform, E. coli and enterococcus.
