Stillaguamish Tribe testing how mushrooms improve water quality

The Stillaguamish Tribe is testing ways to use mushroom spawn to improve water quality in agricultural areas.

The process, called mycoremediation, allows contaminated water to filter through the fungus’ fibrous roots, which helps reduce fecal contaminants.

“Mycoremediation could help improve surface water management on farms by getting rid of fecal coliform without having to excavate or give up farming,” said Kate Konoski, the natural resources technician for the tribe who is conducting the study. “It’s low-impact, low-cost remediation.”

The lower Stillaguamish River watershed is dominated by agriculturally zoned land. Pollutants from farms include excess nutrients, fecal matter and pesticide contaminated runoff. Excess nutrient and fecal loads can reduce available oxygen, while metals and emerging contaminants can negatively affect salmon spawning. (more…)

Pollution Limits Shellfish Harvest In Dungeness Bay

SEQUIM (September 11, 2003) – All of Dungeness Bay will be closed to shellfish harvesting this upcoming winter, eliminating oyster and clam gathering opportunities for Indian and non-Indian harvesters. The Washington Department of Health officially closed the bay to tribal and non-tribal shellfish harvests from November through January, when water quality fails state and federal standards.

That’s a big blow to the Jamestown S’Klallam Tribe, which has always depended on the bay for shellfish. Not only does the Jamestown Tribe harvest clams and oysters along the beach for ceremonial and subsistence purposes, the tribe also operates a commercial shellfish farm in the bay. During the three-month closure, which coincides with the holiday season when clams and oysters are in high demand, the
tribe misses out on much-needed revenue.
