Our mission is to protect the habitat of Puget Sound tidelands from the underregulated expansion of new and intensive shellfish aquaculture methods. These methods were never anticipated when the Shoreline Management Act was passed. They are transforming the natural tideland ecosystems in Puget Sound and are resulting in a fractured shoreline habitat. In South Puget Sound much of this has been done with few if any meaningful shoreline permits and with limited public input. It is exactly what the Shoreline Management Act was intended to prevent.

Get involved and contact your elected officials to let them you do not support aquaculture's industrial transformation of Puget Sound's tidelands.

1997 DOH Testing for Arsenic Results - Did Harvesting Release Arsenic and Cadmium Trapped in Sediments?

[Update 12/20: Alternative link to Arsenic study added and low end of Arsenic corrected, table from 2007 study added.]

 

Was Arsenic found in the DOH Health Consultation 
from 1997 important to pay attention to?

The Washington Department of Health (DOH) has clarified further that the geoduck which the Chinese state tested positive for Arsenic originated in Puget Sound and those testing positive for Paralytic Shellfish Toxin (PST) - also referred to as Paralytic Shellfish Poisoning toxins (PSP) - originated from Alaska. DOH will begin further testing of geoduck tissue in the area.

Tract 10400 is adjacent to 10380 where
it is believed geoduck testing positive
for Arsenic by the Chinese originated from.

In 1997 a Health Consultation report tested geoduck for Arsenic and other heavy metals from geoduck samples in tracts 09950 and 10400. Those tests showed Arsenic levels in geoduck ranging in levels from 2.28 parts per million to 5.02 parts per million (see page 7 of the report referenced above). Whether this should have been significant enough to have alerted DOH to additional testing is an open question.
