6/18/2016 -- TAMPA (FOX 13) - After a first-of-its-kind study, the CDC has released new information about pool safety, and the report isn't good. 

Inspectors collected data in five states -- Arizona, California, Florida, New York, and Texas -- from a total of  84,187 inspections at 48,632 public aquatic facilities. Sixty-six percent of these inspections were of public pools. Hot tubs, wading pools, and interactive water play venues for children were included as well.

After tallying thousands of pieces of data collected in 2013, the CDC found about 80-percent of public pool sites had at least one, sometimes more, code violations. The most common problems were things like incorrect pH levels and safety equipment issues. 

Study: Public pools teeming with bacteria, other dangers

The CDC also found, 1 in 8 inspections ended up with an immediate pool closure. So, what should an average pool-goer do to stay safe and healthy? 

"I think these numbers should be concerning to parents," said FOX 13's Dr. Jo, who echoed the CDC's recommendation of bringing PH strips to pools to self-test the levels.

Proper PH and chlorine levels can help prevent nasty bacteria that can make you sick.
