 From the EPA:

There are numerous concerns about the occurrence and toxicological
significance of various species of organotins in drinking water. A
recent report indicates that unlike PVC systems, new CPVC systems have
the potential to contaminate drinking water with organotin compounds
for a longer period of time after installation (Forsyth and Jay 1997).
