Abstract
The Rio Conchos originates in the Sierra Madre Occidental in northern Mexico.
Its flow is the largest contributor to the Rio Bravo, which serves as part of the
border between Mexico and the United States. Therefore, water quality and
quantity have implications on both sides of the United States and Mexico border.
The objective was to determine the water quality of the Rio Conchos. Six
sampling sites were selected along 560 km of the river. Physical-chemical
characteristics as well as heavy metals (As, Cd, Cu, Cr, Fe, Mn, Hg, Pb and Zn)
were determined. In addition, microbiological and epidemiological tests were
performed. Discharge was estimated and ranged from 0.0931 m-3sec-1 in the Rio
Chuviscar to 2.8348 m-3sec-1 in Valle de Zaragoza. Water samples at Ojinaga, in
the Rio F
