<pre>A "non-potable water" introduces two problems:
1) a mapper may not know if the water is potable or not; there may be no
way to check it or he may not be able to do it; still adding a water source
is useful;
2) I don't like creating too many top-level tags. I could live with it,
however, as long as we don't have a better defined tagging system. But the
previous item is still an issue.

<pre>So what's your suggestion for a water source of unknown potability?

<tt>Where something is 'unknown' one assumes its

Thus a water source of unknown potability should be tagged as
"nonpotable_water" as this maintains safety. </small> </big></tt>
