Surfrider is a nonprofit environmental organization that produces a annual "State of the Beach" (explanation here) report with information about US beach access (public access and private ownership issues), water quality, beach erosion, surfing, links and more. Reports are available for Hawaii, West Coast, Gulf States, Southeast, Mid Atlantic, Puerto Rico, Northeast and Great Lakes. In-depth Water Quality reports for beaches in CA, HI, TX, AL, and parts of FL, as well as results of beach water testing conducted by (or sanctioned by) Surfrider Chapters are also available. There are also Surfrider chapters in: Australia, Brazil, Canada (no website), Europe and Japan. EPA: Beaches is also an excellent resource for information about the condition of US beaches.
