This weekend is Harbor Splash. What does the data show about water safety?

This Sunday, Baltimore Mayor Brandon Scott, Maryland Comptroller Brooke Lierman and a group of 150 registrants will do something once considered revolting: jump into the Inner Harbor. The event, called Harbor Splash, is a milestone for a 14-year campaign that originally aimed to make Baltimore’s waterfront fishable and swimmable by 2020, led by the city’s Waterfront Partnership.
