E.P.A. Posts Results of Additional Samples Taken at the Murphy Oil Location

(10/19/06) On Oct.17, US E.P.A. updated its Hurricane Katrina web location pages to include the results from additional samples collected at the Murphy Oil Location in Louisiana. Pursuant to a FEMA mission assignment, US E.P.A. is overseeing Murphy Oil's ongoing sampling activities of residential and other properties. Today E.P.A. posted samples taken as part of 2 ongoing efforts.

The 1st set of samples relates to ongoing activities to assess the level of contamination at residential and other sites. 10 percent of the samples Murphy collects are split between Murphy and EPA. E.P.A. sends the split samples for independent analysis. Thus far, Murphy has collected 8190 sediment samples from 4930 properties. Of the 8190 sediment samples collected, US E.P.A. has sent 855 split samples for separate analyses. US E.P.A. has received, evaluated and is posting the results of the 1st 841 samples.

Additional soil samples are taken after cleanup at each property to confirm that LDEQ's Risk Evaluation/Corrective Action Plan (RECAP) Requirements have been met. 10 percent of the confirmatory samples Murphy collects are split between Murphy and EPA. E.P.A. sends the split samples for independent analysis. Thus far, US E.P.A. has sent 85 split samples for separate analyses. US E.P.A. has received, evaluated and is posting the results of 81 of these samples. The levels of compounds detected in the samples were either below their respective RECAP Requirements or fell within a risk range which US E.P.A. has found acceptable in other contexts.
