MIAMI (CBSMiami) — The City of Miami closed two more parks Monday in connection to possible contamination.

According to a statement released by the city Monday, recent sampling has revealed the presence of some contamination

Miami-Dade County’s Department of Environmental Resource Management  is conducting  Billie Rolle Mini-park on Grand Avenue and South Side Park located at SW 2nd Ave and 12th street.

The parks are being closed until further sampling can be performed and necessary actions are identified.

According to the city, they are working closely with DERM and the State Department of Health while testing is performed and plans are developed to permanently remedy the issue.

Merrie Christmas Park and Douglas Park were also closed in the past months due contamination.

At a meeting held earlier this month,  Commissioner Marc Sarnoff said Merrie Christmas Park and Douglas Park would remain closed. Blanche Park remains open because artificial turf in the park acts as a protective seal. Sarnoff added that the three parks will be cleaned up in the next year.
