VIDEO: Swimmers jump into water at Baltimore's Inner Harbor

Baltimore's Inner Harbor is beautiful to look at but it's not the cleanest body of water in the world.

That didn't stop a group of apparent tourists from jumping in for a dip last week.

Video posted online by user Milksquad Psycho shows a group of about a dozen jumping into the harbor water. In the description under the video, the user posts, "These guys decided to think jumping in the inner harbor water was fun, but little do they know that the water is crawling with diseases!!!!!"

One person in the video can be heard saying, "They're from Chicago, they don't know no better."

In addition to sewage and trash, pollution from local boat traffic could cause unhealthy conditions for swimmers. Even worse - earlier this month authorities in Baltimore pulled a dead body from the water near the location where the tourists were seen swimming.
