UPDATED: Municipal Water Tainted With "Forever" Chemical

 



min 1 - 1:40 great intro even without video picture
min 1:40 - 4:15 boring chemistry discussion
min 4:15 starting of a very interesting discussion 

Toxic "forever chemical," (PFOS) is explained.  In Redmond wells #1 and #2 it is elevated above State standards .  (See table.)


The City is monitoring PFOS and related forever chemicals quarterly.  Monitoring started on April 2024.  Elevated PFOS levels above Federal standards are in boldface. This table was published in the 2/3/2026 Redmond Council study session packet. 

Reverse osmosis filters, remove ~ 94% of the contaminants. Amazon sells them.

A Call For Action To Test Industrial District For Toxic Chemicals

The Following is Dr. David Morton's public comment to the Planning Commission for "Items from the Audience."  David Morton, PhD is a Redmond resident who regularly speaks at government meetings about ways to improve our environment.  

I’d like to discuss a critical land use issue that affects Redmond's drinking water aquifer, and may cause PFAS contamination in Wells 1 and 2. PFAS is a man-made toxic chemical that never breaks down. It once was used to manufacture firefighting foam.   

Last week, I testified before City Council about PFOS levels exceeding EPA's 4 ppt standard in these wells. Tonight, I want to focus on the land use aspect of this problem—specifically, the Evans Creek Relocation Project and the DTG Recycle site, formerly All Wood Recycling.

The DTG site sits within Redmond’s Critical Aquifer Recharge Area I (where groundwater contamination can reach municipal supply wells in under five years. In August 2013, a massive fire at All Wood Recycling required multi-day firefighting efforts. (See hereherehereand here.) A former Redmond Natural Resources Manager informed the City Council that firefighting foam was used to extinguish that blaze and that about 1900 fish in Evans Creek were killed. *

The concern is straightforward: the foam likely contained PFAS, and those "forever chemicals" may have infiltrated Redmond’s aquifer. Bob Yoder's research suggests additional historic contamination sources at this industrial site—oil spills into Evans Creek, failing detention ponds, and septic systems that may have channeled PFAS-contaminated water underground.

Here's the land use policy problem: the Evans Creek Relocation Project will disturb soil on the DTG property. When the Department of Ecology sampled soil there in 2022, they did not test for PFAS. This is a significant gap in the environmental review process, especially given the site's MTCA contaminated cleanup status and location in Redmond’s CARA I (see the image below).

Since the Planning Commission advises the Mayor and City Council on land use policies, I urge you to recommend that the City require PFAS testing at the DTG site before any ground disturbance occursIdentifying and remediating contamination sources is essential to prevent ongoing pollution of Redmond's drinking water.

With a 2029 EPA compliance deadline and costs for treatment of Wells 1 & 2 potentially in the tens of millions, Redmond cannot afford to overlook potential contamination sources in its CARAs. Sound land use policy demands testing before digging.

I ask that you advise Council to strengthen Redmond’s critical area protections by requiring PFAS assessment before approving projects in CARA zones, particularly on properties with known environmental violations or firefighting foam use.

* See the archived video of the Aug. 27, 2013, City Council Study Session beginning at 1:30:12. The comments about the fish kill and the firefighting foam use begin at 1:31:47.

Updated: The Story Of Redmond's Well Water Contamination

Devices to filter toxic PFAS from well water may be purchased online.

Forty percent of Redmond drinking water comes from five wells, the remainder from surface waters like the Tolt River. At a recent Council meeting, the Director of Public Works Aaron Bert, announced Wells 1 & 2 in Anderson Park were contaminated with a man-made chemical called PFAS, coined a "forever chemical." It doesn't break down and can compromise immunity, lead to cancer, affect pregnancy and other health problems if consumed over a long period of time.

Council hired Hazon consultant ($284,000) to plan a pre-design of filtering infrastructure for Wells 1 & 2. Bert says the estimated cost will be $25-$30 million with projected completion by 2029.

Bert's scientist stated in a February 3 year council meeting they know the source was "historic." but haven't identified the site. Extensive community research concludes the source is likely from fire foam used in 2013 to extinguish a massive debris fire in the neglected SE Redmond industrial district. Jon Spangler, the Redmond Natural Resource manager saw fire foam floating in nearby Evans Creek and 1900 dead fish. Fire Captain John Stockman remembers fire foam was used.

Some fire foams can be highly concentrated with toxic PFAS. Per "aquifer hydrology studies" the contaminated water probably reached Education Hill and North Redmond water supply by 2018, at the very least. My family ordered a "reverse osmosis" water filter from Amazon and are VERY happy with the clarity and smooth taste of the water; and knowing it's PFAS free!

UPDATED 1/28/26: Redmond's Water Supply Wells Contaminated

Forty - five percent of our clean potable water is supplied by five water supply wells; and they are compromised.   Very recent sampling efforts have detected "PFAS" contaminating Anderson Park's two water supply wells (#1 and #2.)  PFAS - are found in paint, cleansers, fire extinguisher foam, other man-made chemicals and *historic spills.  Public Works Director Aaron Bert said in a staff report, "the City doesn't know the source."  

PFAS (per- and polyfluoroalyl subs) are a group of soluble human-made chemicals that can adversely affect human health and the environment.   Higher cholesterol, blood pressure problems during pregnancy. lower birth weights and increased risk of some cancers may occur over an extended period of time.

The sooner the city reaches out to the community to reassure us the better. The estimated cost of mitigation is $25 - $30 million.  On February 3, 4:30 PM in City Hall, Council's consultant will explain how to remove and replace these "forever chemicals."  You are invited or LIVE stream on Comcast Channel 21.   

 HISTORY

Southeast Redmond's industrial district was historically the city "dump site" with abused 50-foot creek buffers and untreated stormwater *spilling into nearby Evans Creek.  (It's been somewhat environmentally rehabilitated.) In 2013, a massive debris fire started in the district at All Wood Recycling - located in the infiltration zone where potable water is drawn from the aquifer.  It took days and volumes of water with *PFAS-laced fire foam to extinguish it. In my opinion, the industrial site is the source.  
Evans Creek runs through Redmond's Industrial District
 and over a shallow aquifer 

Special thanks to Dr. David Morton for his contributions and collaboration on this source-finding adventure.

EXTRA: Alaska Wildlife Refuge Open To Oil And Gas Drilling

 Trump administration finalizes plan to open pristine Alaska wildlife refuge to oil and gas drilling

JUNEAU, Alaska (AP) — The Trump administration on Thursday finalized plans to open the coastal plain of Alaska’s Arctic National Wildlife Refuge to potential oil and gas drilling, renewing a long-simmering debate over whether to drill in one of the nation’s environmental jewels.

U.S. Interior Secretary Doug Burgum announced the decision Thursday that paves the way for future lease sales within the refuge’s 1.5 million-acre (631,309 hectare) coastal plain, an area that’s considered sacred by the Indigenous Gwich’in. The plan fulfills pledges made by President Donald Trump and congressional Republicans to reopen this portion of the refuge to possible development. Trump’s bill of tax breaks and spending cuts, passed during the summer, called for at least four lease sales within the refuge over a 10-year period.

WCC Members To Remove Noxious Weeds, Plant trees

Internet photo

The Washington Conservation Corps (WCC) maintains stream and habitat restoration sites throughout the City of Redmond. Maintenance is typically required by permits for the first 5-10 years after project completion and ongoing maintenance is necessary for long-term project success. 

"Maintenance is a crucial activity to the success of restoration and mitigation . Approximately 100-acres of maintenance sites are distributed around Redmond.  Maintenance of restoration sites involves control of invasive weeds, litter pick-up, replacement planting, and other activities important to overall project success. This regular site maintenance enhances already completed projects, building on the initial investment, as well as improving the aesthetics of sites." 

This project costs $289,880 and includes 4 extra weeks of crew time to assist with large scale noxious weed management and tree planting projects. WCC members are typically college-age students learning restoration techniques and gaining job skills. A crew consists of six staff that work a 40-hour work week, for 42 weeks, primarily managing noxious weeds and installing replacement plantings at City capital improvement projects. In addition, the crew helps with volunteer events, native tree planting, habitat assessment, small stream projects, site monitoring, and de-fishing stream projects.

Meadows, Pollinators, Trees, Seeds and Gardens!


Letter to Council and Office of the Mayor:  

I really likedDeputy Park Director Dave Tuchek's presentation last night:  His naturalized meadow growing efforts will develop this Priority habitat!   His short explanation and education of pollinators was really interesting and brought things into a worldly perspective.  Amazing in-house construction and design of the Anderson Community Gardens!  And, Redmond wild flower seed packets to boot. ☝

Am so happy you are on a Redmond 2050 mission towards 40%tree canopy​; and you are identifying planting locations towards that end.  How will you build your tree stock for these massive plantings? The development community will have to pitch in. 
Please write a modified tree regulation ordinance to balance our tree canopy ​with housing needs.  ​A modified tree ordinance will build replacement tree stock ​and give us a chance to reach 40% canopy by 2050.  
Though you may be targeting low canopy locations, the Heron Rookery has immense cultural, natural, environmental, and historical value.  This forest remnant is a city gem.  I did a planting there last year and the city knows there's root rot and stoney soils.  My wish is you commit to a major understory restoration effort there, and construct narrow pathways for nature walks. Thank you!

UPDATED OPINION: Proposed Tree Code Update Needs Modification To Accomodate Housing Needs

Cottages in Kirkland / photo Master Builders
After removal, replacement trees must be planted on and *off-site.

The City of Redmond is refreshing their Environmental Sustainable Action Plan (ESAP) and wants Redmond 2050 input on trees, EVs, heat pumps and more.  Click ESAP to participate.  

OPINION:  The city has not updated their tree regulations in over 26 years.  They are procrastinating to accomodate  much-needed housing.  The removed trees are replaced with saplings but at numbers that can't reach Redmond's 40% canopy goal.  Off-site planting sites for replacement trees should be identified by Parks, Planning and Public Works to broaden canopy cover. The replacement trees are supplied by the developer and installations financed with one-time money and CIP funds.  

*Suggested off-site planting sites:  Parks, trails, Keller Farm (forested) wetland tree mitigation bank, streets, sidewalks and by-ways, urban growth easements, Light rail stations, M&O Center and other large city projects, the Heron Rookery and western open space,  schools, "plant a tree" neighbohood programs, Hartman forested wetlands, Green Redmond, RTC open space, mouth of Bear Creek, and more.    

According to the Master Builders Association  "A good tree code responsibly maintains or grows the level of tree coverage in a city while also allowing much-needed housing for current residents. newcomers and future generations."    

The city has a 40% canopy goal.  Canopy provides cooling, carbon sequestration, wildlife habitat, aesthetics, raises property values, improves mental health, lowers blood pressure and more. 
In my opinion, the following 2019 tree regulation modifications would improve code to accomodate need for balancing trees with much-needed housing.  It's a compromise:   
  • For every one Landmark tree (30 inches or more) removed, six "replacement saplings trees" (rather than three) must will be planted either on-site, off-site or fee in-lieu. ($2,000.) in that order.  
  • For every one "Significant" tree  (6 inches in diameter at breast height) removed three saplings (rather than one) must be planted either on-site, off-site, or fee in-lieu ($500) in that order.
  • For each tree removed illegally by topping the contractor's penalty will be tripled
  • On-site tree replacements  are aren't required for single family homes.  
Council, the Mayor and the Director of Planning & Community Development need to impliment suggested or similar abreviated code to maintain our quality of life while building much-needed housing.

Kritzer Elected Chair Of Salmon Recovery Council

 


Redmond Council President Vanessa Kritzer Elected Chair of WRIA 8 Salmon Recovery Council

REDMOND, WA - City Council President Vanessa Kritzer was elected to serve as chair of the Lake Washington/Cedar/Sammamish Watershed (WRIA 8) Salmon Recovery Council, a partnership working to protect and restore salmon habitat in the region, including Redmond’s streams. The watershed is also referred to as Water Resource Inventory Area (WRIA) 8 and covers an area of Puget Sound near the shore and inland from the north end of Elliott Bay to south Everett and east to the Bear Creek basin, the Issaquah Creek basin, and the upper Cedar River basin.

“It’s inspiring to see what we can accomplish when we work together, and I look forward to leading on this vital salmon recovery work. I encourage all residents to join in by learning about what you can to support our salmon and a healthier ecosystem,” said Council President Kritzer.

The WRIA 8 Salmon Recovery Council is composed of elected representatives from 29 local governments in the WRIA 8 watershed, plus partners and representatives from community organizations, business, environmental interests, and state and federal agencies. The council oversees the implementation of the science-based Chinook Salmon Conservation Plan, a response to the listing of Puget Sound Chinook as a threatened species under the Endangered Species Act.

Our watershed is home to multiple species of salmon, including Chinook, coho, and sockeye, as well as kokanee, a small red landlocked species native to Lake Sammamish. Salmon are an important environmental and cultural resource for our region, and their survival depends heavily on our choices. Recovery efforts seek to restore salmon runs to levels that would consistently support sustainable runs for tribal and recreational fishing year-to-year.

Updated: Bomb Cyclone Hits Anderson Park


Four Anderson Park landmark trees were blown down in the same western direction by the eastern winds of the "bomb cyclone.".  

This landmark fir crashed into the well pump station and snapped in half.  Amazingly, it was the only park structure hit by a tree.  Power lines down.  No CERT volunteers present.


This park cottonwood fell in a western direction like all the rest.  The large root
balls will be saved and used in rivers, streams, mitigation banks, for erosion control, soil preservation and salmon habitat.  The city does a great job of installing them in Bear Creek, the Sammamish River. and their flood plains.  These 70-year+ old trees are irreplaceable.

Adopt A Stream Drain; Report Spills

 

Make a Difference in Your Neighborhood

Storm Drains News Flash

Adopting a neighborhood storm drain is easy (and fun!) and can help reduce street flooding and keep pollutants like yard chemicals, pet waste, and garbage out of our lake and streams. Most stormwater in Redmond flows into a storm drain—the metal grate in the street – and is carried to a nearby waterway. By spending just 15 minutes a month removing leaves, garbage, and debris from the top of the storm drain, you can help prevent flooding and protect the waterways that are home to salmon, frogs, and other critters.

Sign up to adopt a drain

Report Spills


Help Redmond keep soap, oil, dirt, and other pollutants out of our streams, lake, and underground drinking water sources. Call the City's Water Pollution Hotline any time you see pollutants on the ground, in the street, or in the natural environment. Working together, we can stop pollution in its tracks. Report environmental concerns to Redmond's Water Pollution Hotline: 425-556-2868

Updated 10/27: Neighborhood Stormwater Threatens Sammamish River Salmon.

 In response to this post the City posted this advisory on their website front page.

Redmond's pollution truck advertises their pollution hot line:  425-556-2868 
photo by Yoder


We live two houses up from the intersection of NE 100th Street and 169th Ave. NE.  City public works had two trucks there working on a major drain to "clear up stormwater pollution."  Comcast is planning a downhill dig into 169th Ave. to install new cable that's eroded.  Comcast must have notified the city of a possible pollution problem since there was no "salmon sticker" near the drain.  A sewer line parallels the stormwater pipe making things more complicated.   

Copper residue from vehicular tires and/or fertilizers, car-washing soaps, and lawn mower oils may all have contributed to the pollution.  My guess is the stormwater pollution may have been caused by corrosion from Comcast's aging cable, tire contaminants, a sewer line leak or all three. This particular drain is in a prime location for stormwater run-off; collecting stormwater from two long residential roads. One could say the subject drain services a mini-stormwater watershed. 

  Fortunately, there are two nearby "wet-vaults" just downhill from the subject drain. Vaults treat the stormwater before it eventually enters the Sammamish River where salmon are migrating.  The supervisor said the vaults were fully operational containing only 20% sediment and didn't need to be vacuumed.  While Public Works was there they cleaned out a drain above the house from ours.   

If you have concerns about possible pollution in your neighborhood call the city hotline at 425-556-2868.  I asked the city and two city councilmembers for a "salmon sticker" for this drain and they didn't respond.
