Avalons Dirty Little Secret... http://www.latimes.com/news/local/la-me-avalon-water-20110710,0,5071530.story

By the hundreds of thousands each year, they sail to Avalon by ferry and cruise ship for diving trips, glass-bottom boat tours and to lounge on the beach in the Catalina Island town 26 miles off the Southern California coast.

Yet the same crystal-clear water that draws tourists, also harbors an embarrassing hazard. For most of the last decade, Avalon Harbor Beach has ranked among the most polluted in the state, tainted with human sewage that puts swimmers at risk.

City officials at first suspected boaters who drop anchor in the marina. That was ruled out because of the city's strict dye tablet program that banishes any boater who releases sewage into the harbor.
