Barker Creek cuts through the semi-rural landscape of hobby farms and small towns on Washington’s Kitsap Peninsula. And like many small waterways in this region, Barker Creek has had problems with fecal coliform. Rain washes the bacteria from animal manure and leaky septic systems into nearby waterways.

In some watersheds, the contamination can get so bad that officials have to close shellfish beds and post signs warning people to stay away from the water. EarthFix’s Ashley Ahearn reports on one success story.

Report Details Risks of Proposed Mine Near Alaska's Bristol Bay

Bristol Bay, in Southwestern Alaska, is the home of one of the world’s largest runs of Sockeye salmon. In fact, all five types of salmon spawn in the bay’s freshwater tributaries.

Bristol Bay could also become the home of a new mine to extract copper, gold and other minerals.

The Environmental Protection Agency has released a risk assessment study on how mining could impact the ecosystem there. The Agency will hold a public hearing in Seattle Thursday.

Ashley Ahearn reports that fishermen in the Northwest are watching the process closely.

The ocean absorbs a large portion of the CO2 that we release into the atmosphere from our power plants and tail pipes. But when it gets there that CO2 makes the water more acidic and less hospitable for some creatures, like shellfish. In Puget Sound some shellfish hatcheries have already lost millions of oyster larvae because of exposure to acidic water.

Ocean acidification has scientists and policymakers in the Northwest concerned. Washington Governor Chris Gregoire has convened a panel on Ocean Acidification, which met this week. Ashley Ahearn reports.

Few people know the orcas of Puget Sound as well as Ken Balcomb.

A researcher with the Center for Whale Research on Washington state's San Juan Island, Balcomb has been studying the whales for more than 30 years.

It takes Balcomb only a few seconds of listening to the squeaks and whistles of underwater whale recordings to recognize the different pods of orcas.

In one recording, Balcomb identifies the group known as the L Pod — the family many people in the area are talking about right now.
