Study of Natural Quality Parameters of Groundwater in Dambovita County

Abstract This paper aims to monitor some indicators of groundwater samples from different localities of Dambovita County (Dobra, Valeni-Dambovita, Selaru, Brezoaele), in different seasons (autumn, winter and spring) and compare them with maximum concentrations. (Maximum allowed concentration) provided for in the relevant regulations. The following indicators were monitored monthly for a period of seven months in the above-mentioned areas for groundwater samples: pH, water temperature, air temperature, total hardness (expressed in German degrees), nitrate content, amount of dissolved oxygen, biochemical oxygen consumption in 5 monitored days (BOD5), aggressive carbon dioxide content and carbon dioxide content in the form of bicarbonates. The study identified exceedances of the limit values only for the nitrate content in some localities and in some of the studied months. The other parameters did not show any exceedances.
