Implements water quality indices\nincluding the Water Quality Index ('WQI'/'IQA') using the\nweighted geometric mean following 'CETESB' methodology, the\nTrophic State Index ('TSI'/'IET') after Carlson (1977)\n and Lamparelli (2004)\n,\nand the National Sanitation Foundation Water Quality Index\n('NSF WQI', Brown (1970)). The package also checks compliance\nwith Brazilian standard 'CONAMA' Resolution 357/2005\n\nincluding the legal frequency rule (Art. 15, 80% conformity\nover six or more samples per year), and provides seasonal\nanalysis with regional flow-season calendars, pollutant load\ncomputation, exceedance probability estimation, 'IET'\nvisualization, and multivariate 'PCA' tools for routine\nmonitoring workflows. The example dataset ('wq_demo') is a real\nsubset from 'INEMA' monitoring data from a river in Bahia,\nBrazil (2020-2024).", "License": "MIT + file LICENSE", "Encoding": "UTF-8", "Language": "en-US",
