Bacteria levels up in forest areas but Los Angeles River cleaner
positive takeaway is there is a real potential for revitalization. River, said Kristy Morris, senior scientist with the council. River, ridding the effluent of bacteria and causing the dilution of metal concentrations, she said.
Concentrations of E. coli, a bacterium that can cause sore throats, flu like symptoms or serious illnesses, were above action levels at such popular watering holes as Chantry Flat above Arcadia, Hansen Lake in the San Fernando Valley and Eaton Canyon and the Arroyo Seco in Nike Thea Green
The Forest Service is hard pressed to pick up after hikers, picnickers and bathers who jam the accessible Sturtevant and Hermit falls during the spring and summer months many with dogs who leave behind feces containing E. coli bacteria that get into the streams, the Arroyo Seco and the Los Angeles River.
Conventional wisdom says stay away from the Los Angeles River it a polluted cesspool swirling with contaminants and industrial discharges. Instead, the thinking should be, swim or fish in the river natural tributaries in the Angeles National Forest.
No such treatment plants exist in the Angeles Forest. In fact, the opposite is true. People are adding to the contaminant levels.
The lake is a man made body of water filled up by stormwater runoff and by treated water from reclamation plants operating at Whittier Narrows that clean up underground well water and pump clean water back into the lake, said Mike Whitehead, CEO of San Gabriel Valley Water Co. which is operating the plant.
She said elevated mercury levels of fish in local lakes and streams compare with levels seen in bass Mens Nike Air Max Tavas Essential Running Shoes
At Peck Road Water Park near El Monte and Irwindale, large mouth bass also have higher mercury levels but not as high as those at Legg Lake, Morris said. The council recommends consumption in moderation at Peck Road Park.
Information on contaminated fish, for example, could help governmental agencies put up fish advisory warnings at these facilities.
The full report will not be out until November. Forest Service and other cities can figure out how to clean it up.
should not consume them, Morris said. But carp, catfish and tilapia caught at Legg Lake are safe to eat.
Surprisingly, E. coli levels there are low, Morris said. She said sunlight acts as a treatment plant by zapping the East Fork waters with Womens Nike Air Max Thea Print - Navy/Blue/Pink ultraviolet light, which kills bacteria. River Watershed, many of the tributaries are in shaded areas, so ultraviolet light is not a factor.
Mercury in the air from industrial sources and vehicle tailpipe emissions falls into the lakes, streams and oceans in Southern California. The process is called aerial deposition, Morris explained.
The council surveyed fisherman at Legg Lake and found most are Hispanic and Asian making up the most at risk population. Eating fish with mercury increases the risk of disease for pregnant women and children. Mercury can affect brain function in humans, she said.
The council found that large mouth bass in Legg Lake in the Whittier Narrows Recreation Area is high in mercury. The report recommends fishermen not eat the fish.
it rains, the mercury gets transported from the air to the water, she said.
Well, scientists are proving the conventional wisdom wrong. River is actually cleaner than many popular mountain streams.
decisions based on sound science.
Pasadena. River between the 2 and 110 freeways near Dodger Stadium, where water treatment plants scrub wastewater clean, were free of E. coli and metals, the study found. River habitat is coming back, as evidenced by more willow trees and healthy insect communities.
you don know if conditions are getting better or worse, then how can you manage it? said Brian Sheridan, spokesman for the council. should make 2015 Nike Air Max Womens
The council found elevated bacteria levels at other popular forest locations: Eaton Canyon in East Pasadena, Switzer Falls above La Flintridge and the 9 acre natural Hansen Lake, where boating and kayaking are allowed but not swimming. This is not to be confused with the chlorinated aquatic swimming pool run by the city of Los Angeles.
