ADVICE ON MONITORING THE EFFECTIVENESS OF TREATMENT TO REDUCE PLUMBOSOLVENCY (WTA 9516)
Final Report to the Department of the Environment
The Water Quality Regulations place a responsibility on water undertakers to treat water to reduce lead concentrations in water at consumers' taps. Guidance has been issued to water undertakers on the interpretation of the Regulations. That guidance advises water undertakers to use on-site lead pipe test rigs, or sampling from consumers' taps during field trials, to monitor the effectiveness of treatment to achieve a significant reduction in lead concentrations.
This document provides advice on the construction and operation of lead pipe rigs and on the sampling from consumers' taps for monitoring the effectiveness of treatment to reduce plumbosolvency. This advice draws upon extensive experience by the authors. In particular the document includes:
