"Water quality plunges as pesticide, chemical and bacteria counts rise. Errant boaters sometimes illegally dump their raw sewage into the harbor. And the silt pours in and settles to the bottom of the waterways, making them shallower... This isn't the heavily industrialized Port of Los Angeles. It's affluent Huntington Harbour in Orange County, a Venice-style enclave of million-dollar homes, 3,500 pleasure boats and inviting pocket beaches tucked along the quiet back channels of Anaheim Bay."
