N.  aProspective study on chemometric methods for water classification.h[electronic resource]  c2022  aChemometric methods are currently used very frequently in water analysis. The present work deals with a bibliographic search, considering the scientific and technological developments of the water classification methods, in the area of chemometrics, through the search for articles and patents in the main databases available for research. The prospecting was carried out in the interval of ten years (2010-2020). 126 documents were found in the Scopus database, using the words water quality and chemometrics. Regarding patents, 764 documents were found in the Espacenet database, with 184 filings in Questel Orbit® software, of which 145 are Chinese, 08 are Japanese, 04 are from the United States and 01 from Brazil. Therefore, this study showed a broad scenario for investing, by both public and private authorities. Although Brazil has a considerable amount of scientific articles on the subject, the number of patents has yet to be increased.  aWater quality  aWater quality analysis  aÁgua  aQualidade da Água  aClassificação de Água  aMétodos Quimiométricos  aParâmetros físico-químicos  aProspecção1 aSILVA, P.
