NORTH 25TH STREET GLASS AND ZINC

As of April 2026, the North 25th Glass and Zinc Superfund site is considered “Current Human Exposure Not Under Control” (HENC). Residential soil sampling data indicated elevated concentrations of lead and arsenic in surface soil in the North View residential neighborhood adjacent to the site. Several properties show concentrations of lead in soil that exceed the Regional Screening Level (RSL) of 200 parts per million (ppm) and the updated Removal Management Level (RML) of 600 ppm lead. In 2025, EPA completed a Time-Critical Removal Action at approximately 10 properties with lead results above 200 ppm and where young children and/or expectant mothers reside. These properties were cleaned up to 100 ppm; this removal action was based on the previous 2024 Lead Policy which established an RML of 200 ppm. In October 2025, EPA released a new 2025 Residential Lead Directive increasing the RML for lead to 600 ppm, and the RSL to 200 ppm. In line with the new 2025 Residential Lead Directive, a second Time-Critical Removal Action is being planned for properties with lead above the RML of 600 ppm. A preliminary remediation goal/cleanup level has been established at 200 ppm, the RSL. EPA plans to conduct a Non-Time Critical Removal Action at properties between 200 ppm and the RML of 600 ppm where young children and/or expectant mothers reside. Remaining properties with no sensitive populations will be addressed through a Remedial Action. EPA has provided letters to all property owners that were sampled in July 2023 with the sampling results and additional resources and information to help prevent exposure. For properties sampled in August 2025, letters with sampling results and additional resources will be sent to property owners in Spring 2026. EPA expects to begin the second Time-Critical Removal Action for several properties in Summer or Fall 2026. In addition, EPA is in the process of developing the Engineering Evaluation/Cost Analysis for the Non-Time Critical Removal Action; this document will outline the cleanup options to address the properties with lead levels between 200 and 600ppm and sensitive populations (young children and expectant mothers). Remaining properties without sensitive populations will be addressed by a Remedial Action after the Non-Time Critical Removal Action for sensitive populations has been completed. There are several steps homeowners can take to prevent exposure such as not letting children play in bare dirt, washing hands frequently and removing shoes before entering your home. EPA will continue to provide updates to the community and will remain available for inquiries. EPA currently anticipates that human exposure will be under control by 2032 when all actions in the residential area are expected to be complete.
