Viera, FloridaThe Brevard County Florida Department of Health (DOHBrevard) advises residents living in homes with private wells affected by floodwaters to take precautions against disease.causing organisms that can make their water unsafe to drink.

Drink only commercial bottled water, boiled and cooled, or disinfected by another approved method until your water supply is tested and found to be safe.

Use commercial bottled water to mix formula.

To be on the safe side, you can disinfect tap water by following the procedures below. Do not rely on unverified methods to decontaminate water. If the water is cloudy, let it sit and strain it through a clean cloth, paper towel, or coffee filter. This will facilitate the disinfection process. If you have extra water, put it in containers that have been properly sanitized (see information below on sanitizing water).

The preferred method for disinfecting water is to Boil water.

  • Boil water for at least a minute to kill harmful bacteria and parasites.
  • To improve the flat taste of boiled water, add a pinch of salt (depending on health conditions) to each quart or quart of water, or pour water from a clean container into another clean container several times.

If boiling is not possible, use Household bleach.

  • Add eight drops of unscented household bleach (four to six percent), or about 1/8 teaspoon or a penny-sized puddle, per gallon of water.
    • Do not use color-safe bleach or bleach with added cleaners.
  • If a stronger bleach is used (up to 8.25 percent), add only six drops of bleach.
  • Mix the solution and let it sit for 30 minutes.
  • If the water is cloudy after 30 minutes, repeat the procedure once.
  • If the chlorine taste is too strong, pour the water from a clean container into another and let it sit for a few hours before using.

It is also possible to use other disinfection methods.

Note: Follow the instructions on the product label as each product may have a different strength.

  • Five drops of iodine (two percent tincture) can be added to each quart or quart of water to be disinfected.
    To note: Speak CDCwater that has been disinfected with iodine is NOT recommended for pregnant women, people with thyroid problems, those with known hypersensitivity to iodine or for continuous use for more than a few weeks at a time.
  • If the water is cloudy or colored add 10 drops of iodine.
  • Stir and let the water sit for at least 30 minutes before use.
  • Water disinfection tablets (available at department stores or sporting goods stores) containing chlorine, iodine, chlorine dioxide or other disinfecting agents can also be used.

Water containers should be rinsed with a bleach solution of one tablespoon of bleach per gallon of water before reuse.
