Question 1 of 10 Correct

True or false: That common pool-water smell is an indicator that the water is clean and treated.

Correct! Sorry, that’s incorrect.

The correct answer is: Many people think that the "pool-smell" common in community pools, water parks and hot tubs is caused by chlorine, which means the water's been treated. That's not true. That smell is actually the result of a chemical reaction between chlorine and pee. Yuck!

Question 2 of 10 Correct

Of these, what is the most common bacteria/parasite/virus found in swimming pools?

Correct! Sorry, that’s incorrect.

The correct answer is: Of the pathogens listed, E. coli is the most common contaminant of dirty swimming pools, potentially causing diarrhea, stomach cramps, nausea and vomiting in kids and adults who swallow dirty water. And though E. coli is the most common, the CDC says another bug, Cryptosporidium (Crypto), actually causes the most water-related illnesses.

Question 3 of 10 Correct

How do most dangerous germs end up in pool water?

Correct! Sorry, that’s incorrect.

The correct answer is: The most common pathogens responsible for water illnesses are E. coli and Cryptosporidium -- and these end up in the pool via fecal matter. Keep your community pools, parks and hot tubs clean by showering before and after swimming and staying out of the water if you've had diarrhea.

Question 4 of 10 Correct

This germ can survive for days in chlorine treated water.

Correct! Sorry, that’s incorrect.

The correct answer is: Cryptosporidium is a protozoan that can survive for several days in chlorine-treated water, thanks to its tough, chlorine-resistant outer shell. The best way to avoid it is to keep the germ from getting in the water in the first place -- that means staying out of the water if you've had diarrhea, showering before you swim and keeping diaper germs away from the pool.

Question 5 of 10 Correct

How long does it take for chlorine to kill E. coli?

Correct! Sorry, that’s incorrect.

The correct answer is: Unlike Crypto, which can survive for days in chlorinated water, E. coli is killed by chlorine in less than one minute.

Question 6 of 10 Correct

True or false: Chlorine is the best way to kill germs in a swimming pool.

Correct! Sorry, that’s incorrect.

The correct answer is: Even though it doesn't immediately kill all water germs, maintaining and treating pool water with the right level of chlorine (1-3 parts per million) is still the best way to keep swimmers safe and the water germ-free.

Question 7 of 10 Correct

True or false: Treating a pool with chlorine will completely kill all dangerous germs.

Correct! Sorry, that’s incorrect.

The correct answer is: While chlorine does kill germs in the pool, it doesn't kill all of them. Some types of germs, like the protozoa Crypto, are very tolerant to chlorine, and can survive for days in the pool.

Question 8 of 10 Correct

How long should you stay out of public pools and hot tubs after you've had diarrhea?

Correct! Sorry, that’s incorrect.

The correct answer is: Diarrhea is one of the biggest causes of water-related illnesses, and it only takes a trace amount to cause trouble. To keep from getting others sick, you need to wait at least 2 weeks after it's stopped before getting back into a pool.

Question 9 of 10 Correct

When should you shower if you're planning on swimming in a community pool?

Correct! Sorry, that’s incorrect.

The correct answer is: If you're planning on swimming in a community pool, make sure to take a shower both before and after getting in the water. Showering before swimming helps to keep your germs from getting into the pool, and showering after helps to remove potential germs and contaminants from your skin that you may have picked up from the water.

Question 10 of 10 Correct

Which of these is an illness you can contract from water-borne pathogens?

Correct! Sorry, that’s incorrect.

The correct answer is: Pool parasites, viruses and bacteria can cause a slew of sicknesses, including hot tub rashes caused by the germ Pseudomonas aeruginosa, swimmer's ear caused by bacteria or fungus and stomach problems that are caused by ingesting pathogens like E.coli and Cryptosporidium.
