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 stations were located (Puente 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 were 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 for bacteriological assessment, the average values of thermotolerant coliforms exceeded water quality (1 000 NMP/100 ml) and indicating low organic pollution as a consequence of the contributions or discharges of domestic origin. The SAR index was found values lower than 3, therefore it is not limiting for agricultural activity. It is of great importance to carry out water quality studies of all the river basins in the country, especially the determination of the quality of water for irrigation due to the potential effect on human health and ecosystems.
