EVALUATION OF DRINKING WATER QUALITY CLUJ COUNTY FROM ROMANIA REGARDING NITRATE CONCENTRATION

Full text

The main sources of drinking water in Cluj county include private wells or drillings, rivers, and less lake. In many Cluj county rural areas, the drinking water from private wells is highly polluted with nitrate, as a result of agricultural activity (including excess application of inorganic nitrogenous fertilizers and manures) or seepage of human sewage from private septic systems. This study presents quality assessment of drinking water from Cluj county, regarding nitrate concentration. Drinking water parameter like conductivity, pH, turbidity, nitrite, ammonium, nitrates were investigated. The study was carried out in the January - December, 2015. The nitrate concentrations were low in drinking water samples from surface source in the ranged between 1.68-3.34 mg/L. On the other hand in groundwater samples high nitrate concentration was obtained 4.78-47.81 mg/L, but not exceed the limits indicated by the legislation (50mg/L).
