ecletica-1417	Gadelha, Antonio José Ferreira; Rocha, Clarice Oliveira da; Veras Neto, José Germano; Gomes, Mirelly Alexandre	Multivariate statistical analysis of physicochemical parameters of groundwater quality using PCA and HCA techniques	2023	11	.pdf	application/pdf	5675	258	51	The analysis, monitoring and assessment of underground water quality parameters can be used to detect possible contamination events and as an indication of significant changes in physical and chemical properties of water, thereby avoiding financial and social losses. According to Gomes and Cavalcante (2017), by using the PCA technique, it is possible to select the characteristics with the highest participation in each component and define which physical-chemical parameters of the water should be monitored, thus reducing costs with analyses of factors of lesser importance in water quality.	cache/ecletica-1417.pdf	txt/ecletica-1417.txt
