Purifying by adding liquid chlorine bleach
Treat water by adding liquid household bleach, such as Clorox or Purex.
Household bleach is typically between 5.25 percent and 8.25 percent chlorine. Read the label.
Avoid using bleaches that contain perfumes, dyes and other additives. Be sure to read the label.
Cloudy water should be filtered before adding bleach.
Place the water in a clean container. Add the amount of bleach according to the table below.
Mix thoroughly and let stand for at least 60 minutes before drinking.
