Summary

I found in researching this subject, what is fracking doing to our water supply, the top level domains that seemed to have the most information was the .org and the .com.  The .gov and .edu domains were very concise and had more charts and data supporting their evidence. They all had something to offer and there was a lot to wade through.  Putting in the domains in the advance search site helped a lot in narrowing down the search.  Finding reliable information on this subject and not just opinion was all so challenging.  Using the "about us" helped to determine if the site was credible.  I felt like most of the sites I visited had merit.  I pretty much just stayed away from the blogs and wiki sites.

When searching in the subject directories I didn't find a lot on fracking if at all.  Maybe I was doing something wrong.  I tried about three of them and I used Boolean operators and it still did not give me much info.  Water contamination would come up but as soon as I put the word frack*, fracking, hydraulic fracking in it gave me 0 results.

I think the open web was still harder to narrow down the subject and had a lot of websites, some periodical articles but not many books, unless you went to Google Books.  Then there were books on the subject but then finding out what domain the books fell under was another challenge.   I think I did this assignment correctly but there is still a lot to learn.
