Best Practice Guide on the Control of Lead in Drinking Water
Computational modelling predicts that zones with a moderate plumbosolvency
and more than 30% of houses with a lead pipe will require zone-wide action and
zonal failure profiles give a better insight into likely health significance.

Corrosion and Metal Release for Lead-Containing Materials: ...
Removal of part of NOM by anion-exchange resins or GAC causes a
considerable decrease of plumbosolvency (Colling et al. 1992). When a peat
