SCHAIX - WSCHA As you know, there has been work by various scientists in regard to finding polyohlorlnated biphenyl in marine life. There will certainly be wore work on this, both In the U,S. and In Europe! One of the problems Is that PCB can be detected In parts per billion. Although there are no known hamful effects at these low levels, there are probably soaie uses that eould 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 hunan consumption. Howard Bergen was under the lnpresslon 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?
