Does chlorine get rid of bacteria?
Free chlorine kills most bacteria, such as E. coli 0157:H7, in less than a minute if its concentration and pH are maintained as CDC recommends. However, a few germs are moderately (Giardia, Hepatitis A) to very (Cryptosporidium) chlorine tolerant.
Can you get E coli from a swimming pool?
The E. coli is a marker for fecal contamination. Finding a high percentage of E. coli-positive filters indicates swimmers frequently contaminate pool water when they have a fecal incident in the water or when feces rinse off of their bodies because they do not shower thoroughly before getting into the water.

How does chlorine dioxide kill bacteria?
When bacteria are eliminated, the cell wall is penetrated by chlorine dioxide. Viruses are eliminated in a different way; chlorine dioxide reacts with peptone, a water-soluble substance that originates from hydrolisis of proteins to amino acids. Chlorine dioxide kills viruses by prevention of protein formation.
How long does chlorine last in a pool?
It is also helpful in controlling algae, destroying organic contaminants and restoring clarity. It is best to wait before going into the pool because liquid chlorine levels will be high after shocking, but it will be safe to swim after only 24 hours. Each chlorine compound is designed for a specific purpose.
