More and more utilities are switching to the usage of chloramine, a chemical combination made of chlorine and ammonia.

If Chloramine is the disinfectant, do your study to find the best water treatment option from other reliable sources.

Method…

Obtain a fresh one-gallon container. 500 grams of sodium thiosulfate should be dissolved in a sizable pitcher of warm tap water. Stirring is necessary to dissolve all crystals. After that, pour the mixture via a funnel into a gallon container. To create a full gallon of stock solution, fill the jug to the top with water.

For every gallon of water that needs to be treated, add two drops of the stock solution.
A gallon of stock solution may purify up to 37,850 gallons of water. It is essentially impossible to overdose.
