Of course anything to do with safe drinking water or unsafe drinking water is relevant but being relevant does not mean it belongs in the article If it is relevant and integral to the article in it should go but as far as I can make out it is not integral to this article but to the fraccing issue in general As such it should go into fraccing articles and though it might well rate a mention in this article all such a mention should comprise is that there are concerns and controversies on fraccing safety and desirability with links to the most relevant fraccing articles If you think that those articles do not mention the drinking water issues in sufficient detail and balance go to the fraccing articles to make up the deficiency not here Otherwise we finally wind up with a separate and very likely conflicting fraccing discussion in every drinking water article for every major community in the Eastern US And each of those will need its own updating and reconciliation etc In short a mess Mention fraccing by all means But do not explain argue or enlarge at all in this article If you want to expound feel welcome but do it in articles where it will be appreciated The principle has nothing to do with fraccing as such it has to do with decent construction of articles OH and in case you were about to ask about my personal interests in the matter and my connection with fraccing concerns save yourself the trouble I have none whatsoever and I am not even American nor do I live anywhere near the US
