Baltimore City dumped a huge mound of toxin-laden dirt in a city park and refused to remove it, brushing aside tests confirming the dangers, according to internal documents obtained by The Examiner.

Construction managers for the city told the contractors to leave the dirt at a Wyman Park site near a private school in the city?s Remington neighborhood in November, despite it having twice the toxicity level allowed by the Maryland Department of the Environment, the documents state.
