The rural population from Romania is dealing even today with the absence of access to a sure drinking water source. Therefore in 2002 only 65% of the Romanian population had access to drinking water, distributed in 90% from the urban environment and 33% from the rural one (www.recensamant2002.ro). This work presents a case study referring to a 3 month (April-May-June 2011) monitoring of weekly samples of the quality of well water (10 samples) from Tureni village, Cluj County. A portable multiparameter model WTW 720 Germany was used to measure the pH, total dissolved solids (TDS), electrical conductivity (EC), temperature, oxidation-reduction potential and salinity of the collected water samples (these tests were done on site). In laboratory, using the photometric method (RQ Flex instrument, Merck) we determined : Ca2+, Mg2+, SO42-, Cl- and NO3- (C. Nertan et C. Rosu, 2008). The analyzed well water samples have values over the legally admitted limits by the Romanian legislation for the drinking waters (L 458/2002) in the calcium cation, the nitrate and sulfate anion, but also in the global parameters: salinity and TDS.
