Dear President Lederberg:

For your interest, I am enclosing a copy of a recently
released study on granular activated carbon (GAC) prepared by
the National Academy of Sciences' Subcommittee on Adsorption.
I am also enclosing a document which compares arguments regarding
GAC (including concerns previously raised by you) that we presented
in a February AWWA Journal article to the recent findings of the
NAS Subcommittee.

The Subcommittee's report, it appears to me, supports
the GAC health concerns you have raised with the National
Drinking Water Advisory Council and the U.S. EPA.

Very truly yours,
