MIAMI (AP) -- The city of Miami will test the soil at all its parks after toxic materials were found at two playgrounds.
Assistant City Manager Alice Bravo tells The Miami Herald that one playground was closed Tuesday after county environmental workers found elevated levels of toxic metals.
Samples from the other playground showed arsenic levels more than 30 times the state limit. That park was tested after the county ordered soil sampling within a one-mile radius of the city's old municipal incinerator.
Miami Mayor Tomas Regalado says the city now will test all its parks to ensure that they are safe.
City Commissioner Marc Sarnoff says officials also will research the parks' histories. One of the parks sampled had been a trash pit before it became a park.
