This paper presents an integral study on the quality of the superficial waters in ponds and streams of the watershed of Amajac river. The problems associated to specific pollutants are identified and alternative solutions are detailed to be used in public policies of water resources. Four ponds, one lake and five streams were considered in the study and runoff volume, water speed, and maximum depth were measured. Also, the main physical, chemical and biological parameters were determined: dissolved oxygen, fecal coli forms, nitrogen, phosphorus, sulphate, carbonate, bicarbonate, chloride, and manganese. According to the results, it is concluded that water of the river in Tulancingo city is strongly contaminated.
