Drinking water quality assessment of rural wells from Aiud Are
Journal Title: Advances in Environmental Sciences - International Journal of the Bioflux Society - Year 2011, Vol 3, Issue 2
Abstract
The present paper presents the assessment of physico-chemical quality of drinking water coming from rural wells of Aiud area (villages: Măgina, Livezile, Poiana Aiudului, Vălişoara). Water quality was evaluated through a research project conducted over a period of eight months (October 2009 - May 2010). It consisted of a monthly monitoring of water physico-chemical characteristics of 27 drinking wells from the villages mentioned above. There were monitored monthly in the laboratory the following parameters: pH, temperature, oxidation-reduction potential, electric conductivity, total dissolved solids, salinity, using WTW Multi-parameter inolab 720. In April and May, at the parameters mentioned above were added chemical measurements for the following indicators: Ca[sup]2+[/sup], Na[sup]+[/sup], Mg[sup]2+[/sup], Cl[sup]-[/sup], SO[sub]4[/sub][sup]2-[/sup], NO[sub]3[/sub][sup]-[/sup],PO[sub]4[/sub][sup]3-[/sup], HCO[sub][sup]₃[/sup][/sub]ˉ, which analysis were performed with Dionex Ion Chromatograph System 2100. The results of the chemical analysis were processed using the following methods: linear regression, Pearson correlationcoefficient (r) and water quality index (WQI). This monitoring project was initiated from the premise of a problematic quality of well waters, based on the well known contamination vulnerability of the drinking water in Romania, but the results of this study proved the opposite: the water from the monitored wells had a proper quality for drinking.
