Lead Contamination Found on Seattle Street, Pedestrians Advised to Avoid Block
Tap title to read story
Health officials in Seattle have issued a public health advisory and closed a block in the Interbay neighborhood after discovering hazardous lead levels on a public street. Testing conducted by Seattle Public Utilities in July and August revealed road samples containing 55.3 parts per million of leachable lead and catch basin samples reaching 451 parts per million, significantly exceeding Washington State's hazardous waste threshold of 5 parts per million. The investigation stems from environmental compliance issues at the nearby Dyno Battery facility, which received state regulatory fines in March 2026. A professional hazardous materials crew initiated cleanup operations on August 27, while municipal, county, state, and federal agencies expand environmental testing to identify the exact source and pollution spread. Public Health - Seattle and King County urge pedestrians to avoid the affected block and advise residents to decontaminate shoes and stroller wheels to prevent domestic exposure.
