The park backs up to Cold Water Creek which has dumped radioactive material into the park’s floodplain, contaminating the soil.
The Army Corps of Engineers is overseeing the remediation of the park, and says the contamination is limited to the area’s they have designated.
Still, concerned citizens wanted the park completely closed until the mess was cleaned up.
