The GDWQ WG meeting (Berlin, 2007) agreed on a path forward to ensuring consistency between the new JECFA report and the current background document. The GDWQ WG meeting (Singapore, 2008) agreed to discuss the application of the principle of not deriving a guideline value where it would discourage disinfection to coagulants, post–Fourth Edition.
