The term "purification" has specific connotations which implies that there will be no remaining contamination. In the great outdoors as well domestically, we never really purify water, we treat it in order to reduce levels of contamination down to a level where our bodies can cope. It is certainly misleading to suggest that we are making water pure by adding chemicals such as chlorine and iodine.


This Google Trends analysis shows that Water Treatment is a significantly more searched for term.

  • @stevemarvell Yes, upvote the one you want and/or downvote the other, depending on how strongly you feel about them. It's not always done as explicitly as this, but it's convenient.
