The recent heat wave sweeping the nation has people fleeing the rays and jumping into the water.

But not every watering hole is open to the public, and not everyone is safe. As hot residents cool themselves down in public fountains, city officials are struggling to keep their residents out of unsafe waters.
In upstate New York, where temperatures hit 95 degrees this past week, the Clinton Square fountain located in downtown Syracuse has seemingly turned into an outdoor water park. That's despite the police's efforts to quell the frenzy. Swimming, wading and entering the fountain has been prohibited since its opening a decade ago.
"It's hot!" Syracuse resident Karen Larue, a single mother who brought her 8-month-old daughter, Juliana, to Clinton Square, said. "I don't really like any of the public pools. They're disgusting and too crowded. But the fountain is free, filtered and convenient."
The fountain, which sits in the middle of an open square of benches and tables where locals often play a game of chess or catch up with friends, runs about the length of an Olympic-sized pool and stands about as deep as an average kiddie pool.
Even so, says Commissioner Patrick Driscoll of the Syracuse Parks and Recreation Department, "It was not designed as a pool."
But Larue wasn't concerned. "If we can swim in a lake why can't we swim in a fountain? The water's moving so you've got to think it's filtered. So that's good enough for me," she said. "Two [cops] walked by here earlier for about an hour and they didn't say anything. So where are they? No one's here to tell us no."
In Washington D.C., the fountain at the Navy Memorial presents a sanitation issue.
"We have homeless people wash their clothes in the fountain," Taylor Kiland, vice president of marketing and communications for the Navy Memorial, said. "They also 'release' themselves in the fountain. I've heard of this once or twice."
Kiland says that while people do not often enter the narrow and triangular-shaped fountains that sit at the center of the Memorial Plaza, it is common for visitors to dip their hands in the water during their lunch breaks.
"Everybody has done it. It's just too irresistible," she said.
New York City, which has more than 50 decorative fountains in public parks -- with bathing and cleaning clothing prohibited -- find one of their fountains irresistible too. In an if-you-can't-beat-'em-join-'em spirit, the city recognizes that people in Greenwich Village will play inside the fountain at Washington Square Park.
"At this fountain we maintain a low volume of water and keep it shallow to ensure safety," NYC Parks spokesperson Vickie Karp wrote in an e-mail to ABCNews.com. "This fountain was equipped with a bromine filtration system. Bromine is an alternative to chlorine that also kills bacteria and harmful contaminants but holds up better in sunlight and has less of a chemical odor than chlorine."
New York City's fountains, Karp went on to write, are "equipped with filtration systems and disinfection systems to keep them clean and safe."
But filtration systems do not always make for safe swimming holes. Speaking of Syracuse's Clinton Square fountain, Driscoll said, "It's just not chlorinated enough. When people go into the fountain, that creates immense pressure on the filtration system, and it's just not strong enough to effectively clean the water."
On a recent late afternoon, four college students, cooling off after a day of apartment hunting, stopped by the square.
"We're hot, man," David Nieves, who recently moved to Syracuse to begin his first year at Onondaga Community College, said. "Our car doesn't even have A.C. So we're gonna hit up the mall after this just to get out of the heat."
Although his friends joined the handful of people already wading in the fountain, Nieves didn't think a dip in the water was worth the break from the heat.
"I was like, 'Yo, that's dirty,'" he said. "I wouldn't get in there."
But it wasn't long before Nieves' buddies rejoined him on dry land.
"Everybody out of the water!" a booming voice announced from an approaching city police car.
The Police Department has recently issued warning of ticketing and fines. "We're getting law enforcement out there," Detective Sgt. Tom Connellan of the Syracuse Police Department, said. "We understand it's hot, but that's what public pools are for."
"Violators 16 years and older will be ticketed and fined if they're found in the fountain," added Driscoll.
The price for swimming?
So Syracuse residents may want to reconsider. A trip to the community pool or local lake may be worth the trip.
