Presence of geogenic arsenic caused by thermal activity in the Celaya Valley Aquifer: Environmental implications

Year: 2024

Type: book-chapter

Abstract: In the municipalities of Juventino Rosas, Villagrán, Celaya and Apaseo el Grande located in the Celaya Valley Aquifer (CVA), high levels of arsenic (As) have been reported in different drinking water wells that exceed the maximum limits allowed by World Health Organization (WHO) (0.01 mg/L) and by the Official Mexican Standard of permissible limits for drinking water (0.025 mg/L), however the highest values in the region belong to two hot springs whose values are 0.3 mg/L. The origin of levels of arsenic is considered as geogenic and are related with thermal activity causing the dissolution of the volcanic glass of the ignimbrites of the stratigraphic sequence. Therefore, the regional geology may affect the arsenic concentrations of the CVA and the health of the inhabitants, through water ingestion, being currently a serious problem in the municipalities.
