We’ve routinely reported “brown water” sightings for years – so many at one point, Seattle Public Utilities did a system “flush” in West Seattle in 2016 to try to clear out the rust and other sediment that was getting stirred up. Recently, we heard from multiple West Seattle Junction-area apartment residents with a different sighting in their water – white hair-like “fibers.” Here’s one description:
The hair-like objects range up to about half an inch in length and there was consistently a few in any glass of water. I could not tell if they were plastic, organic, or what. My only rudimentary test showed that they do not dissolve in vinegar. There was no discoloration.
That resident had dealt with SPU and property management among others to try to solve the mystery. SPU is on the front lines in terms of water safety, so we asked them. Here’s what SPU spokesperson Brad Wong told us late today:
Seattle Public Utilities has analyzed water samples from the area around 42nd Avenue Southwest and Southwest Alaska Street in West Seattle after receiving reports from customers of microscopic strands or filaments in it.
SPU believes the strands are a result of a recent algae bloom in one of our water supply reservoirs, which has occurred seasonally for more than 15 years. The water is safe to drink because SPU has treated and disinfected it. The Cedar River supply does not have filtration, but meets treatment requirements with ozone, UV light, and chlorine.
Customers who have concerns can call SPU’s 24/7 Operations Response Center at 206-386-1800. Customers may choose to filter their drinking water or purchase bottled water but should not consider this necessary.
SPU will contact customers who called with concerns and continue to monitor the situation.
The response didn’t explain why these complaints were mainly coming from The Junction; our tipster says the SPU person to whom they spoke didn’t have an explanation for that either. The reader quoted above says an SPU rep told them that the algae bloom was in <strong>Lake Youngs, a source for Seattle city water.
