Impact/Purpose:
The environmental or health problem addressed by the study: Theoretical equilibrium lead solubility simulations based on water chemistry A general description of the work and results: An existing lead solubility model (LEADSOL) was coded in a modern language that makes it accessible for broad use. The implemented code was verified against the LEADSOL results and used to produce new figures highlighting some practical considerations on lead solublity. The long term importance or significance of the findings: Provides a reproducible means of generating theoretical lead solubility simulations. Who would be interested in or could apply the results (e.g. program or regional partners, general public, local communities): Drinking water utilities, researchers, regulators, engineers, Regions, OW
Description:
An existing equilibrium lead solubility model was ported to an open source code format, verified against the original model, and used to simulate the theoretical equilibrium lead solubility under a variety of practical scenarios. It allows the user–selected water quality conditions to be used to simulate lead solubility for a variety of solids controlling solubility. Practical implications and limitations of theoretical lead solubility modelling will be discussed.
