How do I delete a url from a keyword campaign

[PerriCline]

I have a couple of urls that are associated with the keywords in my campaign.  They are no longer valid so how do I remove them?

Do you want them actually deleted or just removed from the search index?

-If you have links going to those pages, a 301 redirect would maintain the majority of the page popularity
-If you own the site, you can request that the URL be removed from Google searches via Google Webmaster Tools:

For deleting the pages, here is a site detailing steps for removing a URL/webpage:

I just need them removed from the SEOMoz campaign reports.
