  Abstract:  

Chemical Analysis of Well Waters of Village of Câmpeneşti, Cluj County, Romania. The proposed study area of Câmpeneşti is located in Cluj County. Only 11% of the population in the rural zone in Romania has access to safe drinking water. Most of human population use wells or springs as the main source of drinking water. Wells are generally less than 20 meters deep and they are not properly sealed. The water samples were analysed for pH, Electrical Conductivity (EC), Total Dissolved Solid (TDS), Oxi-Reduction Potential (ORP), Calcium (Ca2+), Magnesium (Mg2+), Total Hardness (TH), Sulfate (SO42-) and Nitrate (NO3-) using standard techniques in laboratory. Total dissolved solids (TDS) vary between 835 mg/L and 1488 mg/L and well water pHs are slight basic (7..62 – 8.38). Nitrate concentrations monitored in Câmpeneşti groundwaters show that 80% of the well water samples exceed 50 mg/L (WHO guidelines value and Romanian value) and 100% exceed 13.5 mg/L (indicative value of human activities). The nitrate content ranges from 48.1 to 85.2 mg/L. Groundwater nitrate correlates positively with TDS.

Keywords: well water, nitrate, ground-waters, water quality, hardness of water.
