So first, as others have stated, you'll wanted to filter the water, to some capacity, regardless of your method of disinfecting the water. Filtration will remove physical solids and other undissolved matter, reducing the overall bacterial/microbial load that your method of disinfecting needs to account for. In addition there are a couple caveats to each disinfecting procedure:
-boiling water will ensure destruction of all vegetative and spore-forming microbes, however once the water cools there's nothing stopping environmental spores floating in the air, or even the container being filled, from being recontaminated with even a singular microbe.
-chemicals, as they state on their containers, kill "up to 99.99%" of bacteria and yada yada yada. That means if you start with 10000 individual microbes you'll have (roughly) single digits of microbes left; ANY trace of microbial presence after chemical treatment means that they'll start reproducing after the chemical sanitizer is exhausted (all free chemical molecules are no longer reacting to kill, or even inhibit growth of, microbes.
