E. Coli in the Los Angeles River: How Much is Too Much for Recreational User Exposure?

Although the Environmental Protection Agency (EPA) and other agencies have already answered this question by setting guidelines for E. coli limits in water used for recreational purposes, the question is again being debated in Los Angeles. This is because the city adopted a new protocol in October of 2017 that mandates closing the Los Angeles River to recreational users whenever E. coli levels are too high. E. coli in the Los Angeles River The City of Los Angeles approved the new river protocol which was developed by the City of Los Angeles Department of Sanitation (LA SAN), the Los Angeles County Department of Public Health, the City of Los Angeles Mayor’s Office, the Mountains Recreation Conservation Authority, and the Los Angeles County Department of Public Works.

Can Better Technologies Save Endangered California Salmon?

Up until the 1800s, salmon were so plentiful in California that these “ bits of silver pulled out of the water ” could be observed ascending the waterways, thousands at a time, each season. However, decades of logging, the construction of dams, and other human interventions have changed the waterways of the state so significantly that the range of the salmon has been permanently altered. Now, a team of scientists collaborating through the Interagency Ecological Program have developed a plan to improve salmon management and, hopefully, help save the species. Team members from NOAA Fisheries, the California Department of Water Resources, the U.S. Fish and Wildlife Service, the California Department of Fish and Wildlife, the U.S. Bureau of Reclamation, and the U.S.

Weather Extremes Shaking Up Fouling Communities in Urban Estuaries

Marine fouling species may seem to be lowly creatures, situated toward the bottom of that portion of the food chain animals comprise. However, these filter-feeding invertebrates that make their homes on hard underwater substrates such as the hulls of ships are among some of the most successful invasive species. Their secret is simply their ability to latch onto human vehicles and survive. Now, new research on the fouling community in the San Francisco Bay indicates that a single wet winter and the change in salinity that high levels of precipitation bring can knock back the advance of these hearty creatures. Marine biologist Andrew Chang of the Smithsonian Environmental Research Center’s Tiburon, California branch published this new research in December of 2017.
