New stink to an old story?

EDITORS NOTE: Please scroll to the bottom of this post for an update.

Some new controversy is brewing in regard to the rotten egg-like stench we reported along parts of Beach Drive SW.  A neighbor in the 4600 block reportedly complained about the gaseous smell to a King County Wastewater representative and was told that the cause could possibly be related to a recent CSO (combined sewage overflow). At first flush, I would think they are referring to heavy rains we experienced on August 29th which pushed our monthly total far beyond the average.

Another concerned neighbor and I caught up with a KC Waste Water truck hanging out this morning at the base of Jacobson Street. The gentleman in the truck explained that he was tasked with installing sophisticated sensors at different points along the sewer line that would indicate any accidental sewage leaks. He went on to say that most complaints of the odor have been located between around LaRustica Restaurant and about the 5000 block of Beach Drive. Also checked out were the City of Seattle lines that run down Jacobson to the main county line. Where the two lines intersect create what’s called  the SW Alaska Street Seattle Combined Outfall which dumps out into the sound when the Alki overflow treatment plant becomes overwhelmed.



Incidentally, this particular outflow rarely overflows according to report studies (.1% yearly 1987-2007) however it is not uncommon to have some leaky-poos just north at the 63rd St & Alki outflows.



The CSO Status website used by recreational divers and beachcombers has been experiencing technical difficulties and is not showing any real time data for the outflow stations in the immediate area.

King County West Point Treatment is encouraging all residents along the drive to report any stink zones with the exact time they occur. This will go along ways to get to the messy bottom of the mystery. 24 hour odor hotline 206-263-3801

A meeting had been setup between representatives of King County Waste Water Treatment, concerned homeowners and local media for this Friday but has been temporarily postponed.

UPDATE September 25, 2015: We received this email from a local resident:

Hi. Thought I would pass along some information about my morning’s experience regarding the odor on Beach Drive.

Last night when the odor intensified, I called the hotline you posted on the Blog (thanks for that information).  This morning around 11:30 a King County representative came to measure the levels of hydrogen sulfide, the likely gas causing the odor.  The couple of manholes out in front of the house had a zero reading for hydrogen sulfide.  At our deck, water side, the reading was .02.  At the bulk head, the reading was .14.  The rep said this was definitely abnormal and KC continues to be perplexed as to the cause but is actively investigating. 

He expected some public announcement next week on the status of the investigation.

Thanks again for the information on the Blog.  Helps to inform and connect us all.
