A new report has placed a spotlight on the deeper-than-expected toxic contamination at Willamette Cove, revealing that pollutants from past industrial activities have sunk up to three feet below ground, surpassing the original assessment of one to two feet. A detailed 2022 soil study conducted in North Portland, involving 5,130 samples, has provided Metro and the Port of Portland with their most comprehensive insight into the contamination, according to a recent Metro News release.
In partnership with the Oregon Department of Environmental Quality (DEQ), both agencies are analyzing the newly acquired data to tackle the decades-old environmental issue. Closed to the public due to the hazardous conditions, Willamette Cove's cleanup process had originally been slated to include the excavation of 42,000 cubic yards of soil but may now balloon to an estimated 76,000 cubic yards to meet safety standards for future public use.
The revelations pose a conundrum for tree conservation efforts in the area. While initial plans had aimed to preserve native trees, alongside the excavation of contaminated soil, the new findings suggest that most trees may need removal if the cleanup digs down to three feet. This intensifies the cleanup challenge, throwing a wrench into prior preservation plans shared by Metro.
Metro is also navigating complex consultations with tribal governments, and engendering public engagement, as they progress with turning the 27-acre site into a nature park. The enhanced cleanup efforts underscore their commitment to ensuring the future park will be a safe haven for both wildlife and visitors. Once completed, the entire site will be remediated to protect human health and the environment, echoing DEQ's stringent requirements, "Metro remains committed to consulting with the tribal governments and engaging with community members and the broader public as the project to turn Willamette Cove into a nature park continues," Metro affirmed.
