Impact/Purpose:
This paper presents data from actual utility sampling projects to show that high lead concentrations in water exist in contact with lead pipes that is not captured by sampling only the first liter of water. It also demonstrates the usefulness of a computational modeling approach to predict lead levels in housing with lead pipes and the performance of different sampling protocols that could be evaluated for diagnostic or regulatory compliance purposes.
Description:
Computational modeling techniques have been used to very good effect in the UK in the optimization of corrosion control for lead in drinking water. A “proof-of-concept” project with three US/CA case studies sought to demonstrate that such techniques could work equally well in the North American context. The results of these case studies and investigations into sequential sampling methods are summarised. Modeling allied to laboratory plumbosolvency testing offers US/CA Utilities a rapid, low cost option for optimising corrosion control treatment. Sequential sampling was found to be strongly influenced by pipework characteristics and in consequence has limited application.
