The City of Eugene temporarily closed Trainsong Park in January 2022 after dioxins were unexpectedly identified in the park’s soil. Dioxins are a class of toxic chemical produced by industrial and natural sources which, depending on the level of exposure, can increase the risk of cancer or other health effects.

After this discovery, Oregon’s Department of Environmental Quality (DEQ) conducted additional soil testing in February 2022. The results of that testing indicated that only some portions of the park contained soil with elevated levels of dioxins. Those areas were kept closed while the remainder of the park was reopened in April 2022. In February 2023 DEQ conducted additional testing in the park, publishing a report on the findings in June 2023.

In July 2023 the City of Eugene took over the planning for the park cleanup. The City of Eugene is now evaluating options for soil cleanup while pursuing Environmental Protection Agency (EPA) funding to support the cleanup effort.

  • Trainsong Park Soil Testing Update, January 2026

    Phase 1 soil testing in Trainsong Park was completed in December of 2025 which helped determine the testing methods for the second phase of work. This second soil testing phase will start early the week of January 19th and last one week, with completion by Monday January 26th at the latest. This round of testing is being conducted to determine the depth of the soil contamination, if any, in the areas identified as having high dioxin concentrations. The results will then inform the final design of the soil removal and replacement project scheduled for later this summer.
    Both field personnel and equipment in the form of a small soil drill will be on site for this work and the testing will be extensive and conducted in manner agreed upon by the Oregon DEQ. Once the results are known, the DEQ will also have the final say on the approved design prior to the start of construction. Once the details of this construction plan are known, the City will host a public meeting for neighbors to share project details, project schedule, and associated safety information. We'll also answer any questions you may have about the upcoming work.
    In the meantime please reach out to City Staff with any questions you may have and we'll be here to provide more information as we have it.
    Thanks again for your patience with the implementation of this project!

    The City is happy to announce that additional soil testing in areas identified as having high concentrations of dioxin contamination will begin on Friday, November 21st, 2025. This additional testing is to first confirm, with more granularity, the levels of dioxin present in various areas of the site. Once this is further understood, a second phase of testing will explore how deep the contamination may be across these areas. This information will determine the final design for the project scheduled for construction in 2026.

    While the initial phase of testing will be limited to hand sampling by a few technicians, the second phase will employ machinery to test soils in contaminated areas in a grid pattern across the fenced off areas of the park. Once the scope and dates of this piece of the project are finalized, the City will update this website and reach out to our interested parties and partners with this important information.

    We are also looking forward to the start of community meetings for the project in early 2026. Our first meeting will share information gathered from the on-site testing and answer questions about the proposed design and construction process. Later in the spring we’ll host a second meeting to discuss details of the project before it moves forward into construction. Your participation in these events is important as we need your feedback and concerns to be wrapped into the process and the design documents if and as appropriate. Look for more information here in the future and check out the updated FAQ’s for current information. If you have questions in the meantime, please reach out to staff and we’ll be happy to respond.

  • Trainsong Park Remediation to Receive $1.526 Million EPA Grant

    The U.S. Environmental Protection Agency has identified $1.526 million in Brownfield Cleanup Grant funding to the City of Eugene for remediation of Trainsong Park, where sections of dioxin-contaminated soil unexpectedly were found more than two years ago. Funding will be awarded upon completion of the final application step.

    The City applied for the funds last fall and received word of the award this week. In all, the Environmental Protection Agency announced $9,806,874 in grants to expedite the assessment and cleanup of Brownfield sites in Oregon. Eugene’s portion will be used to replace much of the soil at the park as well as to develop a public involvement plan and conduct community engagement activities.

    “We are so grateful for having been prioritized for such a significant amount of funding for the project,” said Emily Proudfoot, landscape architect with the City of Eugene. “It is exciting to know we are close to moving forward with this important remediation work and get this park opened entirely to the community.”

    Soil sampling and testing at Trainsong Park led by DEQ during fall of 2021 identified elevated levels of dioxins in shallow soils. The source of the contamination at Trainsong Park is unknown and unrelated to J.H. Baxter, a former wood-processing facility about a mile away.

    DEQ will help the city implement the cleanup, including removal of dioxin contamination from the park. Dioxins are a group of chemicals that are formed during industrial processes such as the bleaching process in pulp and papermaking. They are also present in some wood treating formulations and can be generated during the burning of organic materials, including wildfires.

    “It is a point of livability to ensure all parks in every area of Eugene are safe for families to visit,” said Proudfoot. “We appreciate the partnership of Trainsong neighbors who offered feedback on this project both in the past and in the future.”

    Formal government agreements must be finalized before funding is awarded and work can begin at the park. A rough estimate would have the remediation work beginning in 2025.

    The City wishes to thank Congresswoman Val Hoyle, Active Bethel Citizens and Beyond Toxics for the support they offered in procuring the funding.
