Google has enhanced their Webmaster tools to include new
functionality which enables users to remove content from their index.
There are four different types of removal available to confirmed
Individual URLs: removes one particular URL.
Directories: removes all pages within a directory of your URL.
Entire Site: removes your entire site!
Cached Copy: if you want a page to be listed, but not cached.
There is also a third party removal option, if a site is no longer live
and it still appears in the index you may send Google a request and if
this is indeed the case the site will be removed from the index. There
are various other removal options like removal of sites if your privacy
is being invaded by them and also the ability to flag adult sites that
have slipped through Google’s filter.
