In Romania, in rural areas, water from shallow groundwater is used for both drinking and irrigating the field crops. In this respect, irrigated agriculture depends on a good quality water supply. Currently, at the national level, there is no unitary approach to the quantitative and qualitative indicators of irrigation water. In order to assess the quality of the water, it is compulsory to carry out periodically complex physicochemical analyses, because the quality of the water is changed over time, under the influence of both environmental and anthropogenic factors. Romania has adopted a series of normative acts regarding the use of irrigation, such as the Convention for climate change and biological diversity ratified in 1994 at the Paris Convention (i.e., Law no. 111/1998). In this study, 80 samples of shallow groundwater from rural areas were collected following the EPA Groundwater Sampling – Operating Procedure. The measurements of water temperatures, pH, electrical conductivity, total dissolved solids, and salinity were performed using multiparameter equipment (Consort 3030). Alkalinity was determined by titration methods in order to quantify the carbonate species in the drinking water samples. The metals (Fe, Mn, Cr, Pb, Ni, Zn, Al, Cu, and Cd) were measured in the drinking water samples using inductively coupled plasma-mass spectrometry (iCAP™ Q ICP-MS). The ions concentration (Ca2+, Mg2+, Na+, K+, Cl-, HCO3 -, SO4 2- , NO3 -) were determined by ion chromatography (Thermo Scientific Dionex IonPac system with AS15/AG15 and CG16 /CS16 columns). The Water Quality Index (WQI) and National Sanitation Foundation Water Quality Index (NSDWQI) were calculated. On the other hand, the spatial maps of the groundwater quality based on the suitability of water for ecology were achieved.
