hydrochem: Analysis and Visualization Tools for Hydrochemical Analysis
Provides a comprehensive suite of tools for processing,
analyzing, and visualizing hydrochemical data in a reproducible and
programmatic workflow. Implements unit conversion, censored data
management, ionic balance calculation, water type classification, and
a range of hydrochemical indices relevant to water quality assessment.
Offers advanced visualization functions for generating

and ternary diagrams — the standard
graphical tools used in hydrochemical interpretation. Unlike existing
solutions that rely on spreadsheets or proprietary graphical software,
'hydrochem' is designed for scalability and reproducibility, lowering
the technical barrier for hydrochemists working with datasets of
varying complexity. It integrates seamlessly into modern R workflows
and supports rigorous water resource management and research.
