water_df

A dataset containing fabricated water quality to use as tidywater inputs.
Parameters are set to reasonable water quality ranges. Parameters are as follows:

datasets

Provides multiple water chemistry-based models and published empirical models in one standard format.
Functions can be chained together to model a complete treatment process and are designed to work in a 'tidyverse' workflow.
Models are primarily based on these sources:
Benjamin, M. M. (2002, ISBN:147862308X),
Crittenden, J. C., Trussell, R., Hand, D., Howe, J. K., & Tchobanoglous, G., Borchardt, J. H. (2012, ISBN:9781118131473),
