SCHJUX - W3CHA As you know, there has been work by various scientists In regard to finding polychlorinated biphenyl In marine life. There will oertainly be more work on this, both In the U,S. and In Xuropel One of the problems is that PCB can be detected In parts per billion. Although there are no known harmful effects at these lot levels, there are probably some uses that could be questioned and would be hard to defend. One such use would be In paints for the Interior of water towers, where the water is primarily for human consumption. Howard Bergen was under the impression we were asked about this specific use several years ago and did approve it. Do we know of any customers formulating paints specifically for water towers? bln H^-'f , un I / fa** /vw )u,k 1- 2 f Martin: Would you please have someone calculate the probable level of PCB in water from a water tower painted with Aroclor formulation?
