Analysis for bis(2-Ethylhexyl) phthalate at Outfa11001
Dear Mr. Doll,
Enclosed are the analytical results from the two most recent Outfall 001 analyses for
bis(2-Ethylhexyl) phthalate which shows that this compound was below the method's
detection limit.
These results should verify that the analysis of 81 µg/L bis(2-Ethylhexyl) phthalate at
Outfa11001, as reported for the 1995 OCPSF Priority Pollutants annual monitoring, was
probably from cross -contamination of the sampler's synthetic rubber gloves.
As we have discussed, this site has never purchased nor manufactured, as products or
by-products, any of the phthalates.
If you have any questions, please feel free to call me at [phone].
