Water quality for agriculture use in Jequetepeque middle river basin, Peru

Abstract

This research had the main objective to determine water quality for agriculture use in Jequetepeque middle basin river, Peru. Six sampling station were located (Kuntur Wasi bridge, La Monica sector, La Capilla sector, Yatahual village, El Pongo village and Yonan bridge). The physical-chemical, bacteriological parameters and SAR index was determined. The water quality in the study area was found within the Water Quality Standards by Supreme Decree N°004-2017-MINAM, according to Category 3: vegetable irrigation and animal drink, and D1: vegetable irrigation, it used without restrictions for different crops. It is important in relation to bacteriological assessment, the average values of thermotolerant coliforms exceeded water quality (1 000 NMP/100 ml) and indicating low organic pollution as consequence of the contributions or discharges of domestic origin. The SAR index found values lower than 3, therefore it is not limiting for agricultural activity. It is great importance to carry out water quality studies of all river basin in the country, especially to assess water quality for irrigation due to potential effect on human health and ecosystem conservation.
