PCB Contamination at Sky Valley Education Center and Other Schools in WA

Sky Valley Education Center in Monroe and other schools in WA State are contaminated with dangerous levels of PCB’s and their by-products, including dioxins and furans.

“Dioxins are highly toxic and can cause reproductive and developmental problems, damage the immune system, interfere with hormones and also cause cancer.”

Dioxins and their effects on human health


As a public service to the community, ICWA is publishing the THE RESULTS OF AN ENVIRONMENTAL INSPECTION, which has been made public.

This letter includes the “Analysis Results for Chemicals at the Sky Valley Education Center, Monroe, Washington, Collected in January 2019, that Require State and Federal Environmental and Health Protection Agencies to Investigate and Certify that the School is Safe for Occupancy and Use.”

A top environmental testing company anaylst reported:

“I have received the information that you sent to me regarding the transmittal of samples, laboratory analytical results and a summary for polychlorinated biphenyls (PCBs), polychlorinated dibenzodioxins (PCDDs), and polychlorinated dibenzofurans (PCDF). All samples were taken at the Sky Valley Education Center (SVEC) in Monroe, Washington, on January 4, 2019by Environmental Health & Engineering, Inc. (EHE), a national consulting firm based in Newton, Massachusetts. The samples were shared with representatives of the Monroe School District, and Monsanto Chemical Company at the time that they were collected, so both named parties have samples equivalent to the ones whose analytical results were sent to me.

EHE had the samples analyzed for PCBs. Six samples were additionally analyzed for PCDDs, and PCDFs, over the next two months. PCDD and PCDF results from all six of the indoor samples analyzed for these chemicals were well above the federal ATSDR screening level of 50 parts per trillion (ppt; equal to 50 picograms per gram of material sampled), and five of the six samples were above U.S. EPA’s draft cleanup standards (cited by the State of Washington’s Department of Ecology in 2011). All six samples also exceeded U.S. EPA’s November 2018 Regional Screening Level, residential soil cleanup guidance level of 4.8 picograms per gram (ppt) by 10-100 fold. Five of the six samples analyzed were taken from indoor areas representative of what children and teachers could have been exposed to through 2018, in spite of cleanup and maintenance performed in the SVEC school environment. This is unacceptable, and may represent an extremely toxic indoor environment. These results occurred after the school district cleaned up the SVEC in preparation for the site inspection and sampling by EHE – in December 2018, according to information that I was given at an informal meeting with former teachers at the school prior to the site inspection, and consistent with the signs of intense cleaning that I observed during my inspection of the school on January 3, 2019.”

NOTICE TO Governmental Agencies Regarding PCBs

From the WA State Department of Ecology:

What are PCBs?

PCBs were produced for commercial uses from about 1929 until the 1976 Toxic Substances Control Act banned the chemicals for most uses and restricted PCB concentrations to low levels. PCBs were used mostly in heat transfer fluids in electrical transformers and capacitors, but also as plasticizers, wax and pesticide extenders, and lubricants. Caulk that seals cracks in buildings used to contain PCBs at high levels.

Electrical transformers and other products made before commercial production of PCBs ended may still contain PCBs. New products can also contain PCBs at low levels, either as unintentional contaminants or as inadvertent byproducts during manufacturing.

Washington residents are primarily exposed to PCBs through diet — often by eating fish that contain PCBs.

Toxicity and health effects

PCBs have toxic effects to the immune, reproductive, nervous, and endocrine systems in people and other organisms. PCBs also cause cancer in animals and are likely to cause cancer in people.
