Drinking Water Samples

This work presents the study and determination of composition of natural water samples collected from five different types of water sources from Republic of Moldova and Romania: river, lake, spring, fountain and rain. The purpose of this study was to establish whether some of the heavy metals and organic compounds with impact on population health are present in drinking water samples and if their presence falls within the set limits by national regulations. The analysis has been performed using VIS spectrophotometer with RFID technology and individual parameter express cuvette tests for water analysis which allowed ensuring high accuracy of the measurements. Thus, over limits high rates of Pb2+ and Ni2+ have been found in all samples. A high concentration of F- was determined from fountain water - 2.92 mg/L and of Fe from river - 0.701 mg/L, which is twice than admissible values. The lowest concentration has been measured in the rainwater. Keywords: water samples, heavy metals, organic compounds
