How to Use Calcium Hypochlorite for The Survival Mom

I asked Alan about the use of calcium hypochlorite, aka pool shock, for purifying water because I wanted an expert to weigh in on this popular survival and prepper topic. Ive written directions for its use in purifying water here. Here is what Alan had to say Lisa, I would agree that calcium hypochlorite can be used to disinfect water.

Cyanide Destruction Hypochlorite / Chlorine

The method has been applied ever since in a variety of forms. The active reagent for chlorine oxidation of free and complexed cyanide is the hypochlorite ion, produced when chlorine dissolves in water, as described. Alternatively, hypochlorite ions can be produced by dissolving suitable salts, such as sodium or calcium hypochlorite, in water.

Mining Water for all

Mining produces mainly tailings (the waste materials left after the valuable ore is separated out) and overburden (the waste materials removed to reach the ore). During the mining process, water within and around the mine is usually contaminated, so treating the mine water before it is discharged back into the environment is a major issue [2].
