In German forum was a discussion about it some weeks ago: 
http://forum.openstreetmap.org/viewtopic.php?id=17149

Result:
drinking_water is used as a official information with controlled quality 
etc. ( I think, it is to "German") and shouldn't be used also as "I 
drunk it and are still alive".

But I think it's a useful feature to have the second information also in 
the data. Because local mapper should know better, if it could be 
drunken without a risk or if there is chemical industries some km above.
