From the EPA website:
EPA is currently collecting and analyzing water and sediment samples to help states and other federal agencies understand the immediate and long-term impacts of oil contamination along the Gulf coast and to ensure that residents in affected areas have access to information about the quality of their water. The results and the interpretation of all data collected by EPA will be posted to http://www.epa.gov/bpspill as often as it is available.
A quick search of the URL listed above brings one to a page that lists some basic and rudimentary results of recent air, water, and sediment tests.

We are aware that oil is present on some beaches and marshes along the coastline and are collecting samples in or close to these areas. It takes several days from the point of collection to posting the data on the website so data posted may not reflect real-time conditions.Map of Louisiana sampling locations
