Four beaches have been polluted and more may be closed as city workers scramble to stop raw sewage from being spilled after a blast at a Harlem wastewater-treatment plant, officials said yesterday.

The Department of Environmental Protection is warning would-be swimmers not to enter the water at South, Midland and Cedar Grove beaches on Staten Island and Sea Gate in Brooklyn until Monday. Also, the Hudson, Harlem and East rivers won’t be fit for water contact.
