N2 - Ten wells in northern Mexico were analysed for 47 water quality constituents to determine the seasonal drinking water quality variations and their suitability for human consumption. Parameters examined include 25 major/trace elements analysed by inductively coupled plasma-mass spectrometry (ICP-MS). Total dissolved solids, sodium and sulphate concentrations were above the World Health Organization (WHO) guideline values in 30% of wells during the first and/or the second sampling season. Additionally, only 30% of drinking water samples were found biologically unfit for drinking purpose because total and fecal coliforms were above the guideline values. The drinking water quality index of this area ranked from 'good' to 'excellent'. However, considering that some parameters are above the WHO guideline values, we recommended a monitoring program for biological and chemical pollution of drinking water in order to reach a possible solution knowing the human and ecological risks involved.
