Fluoride and Arsenic in an Alluvial Aquifer System in Chihuahua, Mexico: Contaminant Levels, Potential Sources, and Co-occurrence

The objectives of this study were to identify potential sources of As and F within an alluvial aquifer system in central Chihuahua, to evaluate their change in concentrations with time, and to determine their degree of co-occurrence. The As content in rock, sediment, and groundwater samples was firs...

Description
Summary:The objectives of this study were to identify potential sources of As and F within an alluvial aquifer system in central Chihuahua, to evaluate their change in concentrations with time, and to determine their degree of co-occurrence. The As content in rock, sediment, and groundwater samples was first determined in 2004; later on, in 2007 and 2010, the content of As and F in groundwater was measured. From 34 wells sampled, seven had As levels above the Mexican maximum contaminant level of 0.025 mg L −1 , and 13 wells surpassed the F value of 1.5 mg L −1 , all of these near the town of Aldama. The surrounding rocks contained enough As and F to support a geogenic origin of these contaminants, especially evident in rhyolites. A correlation between As and F suggests a co-occurrence of these two contaminants ( r  = 0.720; p
