Results are in for samples taken on 9-16-10 and 9-23-10. Although tarballs were again present on the beaches, no oil compounds were detected above 5ppm.
The 9-16 sample from Blue Mountain Beach was positive for Propylene glycol at 30.6mg/L.
This is well over three times the reporting limit and considered a significant result. Propylene Glycol is one of the components of dispersants. The sample is being further evaluated to determine if other components of Corexit are also present and to help differentiate from other pollutants.
