The anthropogenic inputs have highly increased nitrate loads into ground and surface waters. All these factors have had a drastic impact on aquatic environment, human health and flora and fauna. Hence, the identification of nitrate sources is valuable in conserving water quality and achieving sustainability of the water resources. The present paper aims to present a clearly image of water pollution in South and South Est part of Romania. The dataset for ammonium (NH4+), total nitrogen (Ntot) and nitrite (NO2-) was collected from 2013 -2017.
