In recent years, the Samish River Basin in Skagit County has suffered severe pollution from fecal coliform bacteria. Water polluted with untreated sewage and manure leads to frequent closures of shellfish beds and beaches. County authorities are testing a new method to find the sources: poop-sniffing dogs

A rubber adapter may be the answer to preventing illegal dumping in local waterways, according to a new campaign by Washington Sea Grant.

The pathogens in untreated wastewater can cause everything from minor skin rashes to serious gastrointestinal illnesses like Giardia and norovirus. But it happens, and often by accident. Many boaters know better, but lack proper equipment or information on how to pump out safely.

The city of Seattle and King County will spend $1.46 billion on upgrades to public sewer systems aimed at reducing the amount of polluted water entering the Puget Sound and other waterways, according to a federal settlement filed under the Clean Water Act. 

Under the agreement, the city and county will also pay $750,000 in fines for dumping raw sewage into the Sound and several lakes.

A more efficient way to fix one of Seattle’s most embarrassing environmental problems – that’s the promise of a proposed agreement on meeting federal standards for clean water.

The problem is untreated sewage that flows into our lakes and other waterways after big storms.

It's a dirty topic with a refined name: Combined Sewer Overflows (CSOs). When heavy rains exceed the capacity of Seattle's century-old drainage system, raw sewage gets dumped into our rivers, lakes and Puget Sound.

Seattle Public Utilities (SPU) is developing a Long-Term Control Plan for limiting CSOs to no more than one outfall per year.
