RT Journal Article T1 Estudio preliminar del contenido de arsénico de las aguas subterráneas del suroeste de Uruguay T1 Preliminary study on arsenic contents in groundwater from Southwestern Uruguay A1 Manganelli, A. A1 Goso, C. A1 Guerequiz, R. A1 Fernández Turiel, José Luis A1 García Vallès, Maite A1 Gimeno, Domingo AB This work presents new results on the arsenic distribution in the groundwater from the SW of Uruguay.This preliminar y study is based in 28 samples from the Aquifer Systems Chuy, Raigón and Mercedes. Thearsenic concentrations observed exceed some thresholds of the Uruguayan and other (e.g., WHO)regulations of water quality. The median, maximum and minimum determined have been 16.9, 58.0 and0.1 μg/l, respectively). There is a horizontal and vertical variation of the concentrations considering alltogether the studied aquifers and also within them. The higher values have been observed in the MercedesAquifer in areas near the Uruguay River YR 2006 FD 2006 LK http://hdl.handle.net/10272/8473 UL http://hdl.handle.net/10272/8473 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 31 may 2026
