Preliminary tests show the four beaches set to open for the first razor clam dig of the season, beginning Oct. 25, have low levels of domoic acid.

All four beaches, Long Beach, Twin Harbors, Copalis and Mocrocks, had acid levels less than 1 part per million when test Oct. 8. The state closes beaches to digging when levels reach 20 ppm.

This was the first of two rounds of testing required by the state Department of Health for each razor clam opener.

Results from the final round of razor clam samples to be tested should be available by Monday.

Four nights of digging are scheduled at Twin Harbors Oct. 25-28, while Long Beach, Copalis and Mocrocks are scheduled for two evening digs Oct. 26 and 27.
