How do I purify water?

Boil water at a rolling boil for 10 minutes. A pinch of salt added to each quart of water improves taste. You can also purify water with two chemicals: chlorine bleach and iodine.

Chlorine bleach (unscented) such as Clorox or Purex. Check the label to be sure that hypochlorite is the only active ingredient. Do not use bleach that contains soap.

Use the following amounts:

  • 1% chlorine - Add 40 drops of bleach/ gallon of water
  • 4 to 6% chlorine - Add 8 drops of bleach/gallon of water
  • 7 to 10% chlorine - Add 4 drops of bleach /gallon of water

Mix bleach into the water and let stand for 30 minutes. Water should have a slight chlorine odor. If it doesn't, repeat the process and let the water stand for an additional 15 minutes.

Iodine. Iodine from your medicine chest can also be used to purify water. The iodine should be 2/United States Pharmocopeia(U.S.A.) Strength. Add 20 drops/gallon of clear water, and 40 drops/gallon of cloudy water.

Water purification tablets are available at drugstores. Follow manufacturer's directions.

STARKVILLE, Miss. -- In the aftermath of Hurricane Katrina, Mississippi State University leaders realized the importance of instituting a standardized response system to assist with all types of catastrophes that might strike the state.

Six months after Katrina, the MSU Extension Service Center for Government and Community Development began training university employees, as well as local emergency management officials, 911-call-center operators, and elected and appointed officials.

STARKVILLE, Miss. -- In the hours immediately following Hurricane Katrina’s landfall, a team of Mississippi State University veterinarians specially trained to work with animals in disaster situations arrived at the state’s designated animal disaster relief shelter in Jackson.

While the Mississippi Animal Response Team’s immediate focus was to assist the Mississippi Board of Animal Health with assessing and managing the growing number of displaced animals, they also had other duties.

LOUISVILLE -- Disaster assessment teams with the Mississippi State University Extension Service are providing “boots on the ground” as agricultural landowners begin the process of recovering from the April 28 storms.

“These trained teams can assess immediate and long-term needs,” said Elmo Collum, a disaster response coordinator with the MSU Extension Service. “They may discover issues that need to be addressed immediately, such as an injured animal, or they may see things that will take weeks of effort, such as fence repair.”
