PORT ANGELES – Residents of about 240 city of Port Angeles homes will have to continue boiling their water.

Due to a lab mix up, the city can’t verify that the water in the southeast portion of the city is safe to drink.

The city had conducted a water main repair for the area on Friday. An advisory to boil water into the weekend has now been extended to last at least another 24 hours, bringing the total time for the advisory to nearly 5 days.

City officials say they are working with the lab to troubleshoot how to prevent from this from re-occurring.
