Puget Sound Sewage Spill Raises Issues

"It's unnerving to consider what poured into Puget Sound last week during King County's worst sewage spill in decades:

Toilet tissue, bacteria, viruses, coffee grounds, pharmaceuticals, heavy metals, holiday spices — and untold amounts of human matter better left undescribed.

Yet just days after a malfunctioning switch at a wastewater-treatment plant released an Exxon Valdez-scale dump of raw sewage, contamination levels in Elliott Bay were returning to normal.

Experts said that's because a 10-million-gallon shot of untreated wastewater, while unacceptable, pales when compared with the toxic insults funneled into the Sound legally every day."
