Abstract

Arsenic contamination of groundwater has been detected in the Zimapan Valley, Mexico. Concentrations as much as 1.097 mg/L were observed in water pumped from one of the most productive wells. Three sources of arsenic are known. The natural source is produced by the oxidation of arsenic-bearing minerals; polluted water pumped from the deepest wells is derived from this source and has the highest concentrations. Two anthropogenic sources pollute the shallow wells. These result from the leaching of mine tailings and from the percolation of smelter fumes containing arsenic and which settled on the soil until the 1940's. The identification and evaluation of multiple sources of pollutants in aquifers are needed to establish reliable aquifer-remediation programs, especially in many arid regions, where groundwater in commonly the main or only source of drinking water.
