Upon assessing the radiation levels, the EPA determined that Hahn's mother's property posed an imminent threat to public health and designated it as a Superfund site.

The EPA conducted a thorough cleanup operation, involving the removal of the contaminated potting shed, surrounding soil, and household items. The process was complex and expensive, costing tens of thousands of dollars.

While the EPA successfully mitigated the immediate risks posed by the radioactive contamination, the incident left a lasting environmental impact and served as a cautionary tale about the potential consequences of amateur experimentation with hazardous materials.
