An assessment, by computational simulation, of random daytime sampling for the optimisation of plumbosolvency control treatment measures

Abstract

The random daytime sampling of lead in water supply zones has been proposed as the basis for optimising plumbosolvency control. This is because of its low cost, simplicity, efficiency and low customer burden. Extensive computer simulation, comprising a zonal lead emission model coupled to a sampling model, has been used to investigate this method of sampling, enabling far more comprehensive study than practical experimentation allows. The computer simulations have confirmed that random daytime sampling is not suitable for differentiating the effects of water treatment, particularly in the optimisation stages. It has also demonstrated the lack of reproducibility in such sampling.
