- Abstract
The article presents a study on the groundwater geochemistry of the Chihuahua City region in the Rio Conchos Basin in northern Mexico, and its implications for water resources management. Results showed that the background groundwater chemistry upstream of Chihuahua City results from feldspar weathering but beyond Chihuahua City, the chemical conditions are strongly modified owing to the disposal of sewage from public and industrial water supplie into the Rio Chuviscar. As a consequence, anions like chloride and and sulphate are mainly linked to surface sources, while nitrate is controlled in part by sewage from public supply and industry and in part by agricultural practices.
