In bentrueman/shinypbcusol: Calculate Lead and Copper Solubility Using Shiny

shinypbcusol

shinypbcusol provides a convenient interface for pbcusol (Trueman, 2021; Dunnington, 2019) using shiny (Chang et al., 2021).

Getting started

The shinypbcusol app is available here.

Currently, it generates lead solubility predictions using the LEADSOL (Schock et al. 1996) and minteq.v4 (Charlton and Parkhurst, 2011; Parkhurst and Appelo, 2013) databases. Lead binding to humic substances is modeled using an approximation to the Windermere Humic Aqueous Model (Tipping and Hurley, 1992; see pbcusol::eq_sol_wham()). Lead concentration is shown as a function of stagnation time inside a lead pipe using a model described by Kuch and Wagner (1983).

shinypbcusol can also be accessed via R. Install the development version from GitHub with:

# install.packages("remotes")
remotes::install_github("bentrueman/shinypbcusol")
