["Beach closings due to hazardous bacterial contamination in Los Angeles County jumped 50% in 2005, hitting a record high for the third consecutive year. More rain and better measurement methods accounted for much of the increase. Across California, the report showed 5,175 closings and health advisory days at beaches last year.... The pollution comes from a wide mix of sources scattered across the Los Angeles Basin, including animal waste, factories, septic tanks, sewage, pesticides and oil and metals deposited on city streets." Los Angeles Times (August 3, 2006) 1.]
