Budeasa, ecological and drinking water quality.
The Budeasa Dam is part of the Argeş River Basin, which is located in the central-southern part of the country, being between the following geographical coordinates: 43°54'50" - 45°36'30" north latitude and 24°30'50" - 26°44'25" east longitude. It borders the Olt Basin to the north, the Vedea and Olt Basins to the west, the Danube Basin to the south, and the Ialomiţa Basin to the east, with an area of 12,550 km2. The total theoretical water resource is 3,282 million m3, and the usable resource is 2,574.279 million m3 (surface and underground resources). To ensure the water source for various uses, 24 important reservoirs were built with a useful volume of 798.82 million m3. In this paper, we aimed to monitor the ecological quality status of the Budeasa Reservoir during the period 2018-2022. To achieve the proposed goal, we established the following objectives: analysis of the values of physico-chemical parameters in terms of the quality standards that surface waters used for drinking water must meet; analysis of the values of microbiological indicators in terms of the quality standards that surface waters used for drinking water must meet; Study of the dynamics of seasonal variation of limnoplankton during the studied period; analysis of the ecological quality status based on the phytoplankton biological element and the calculated Multimetric Index (MI). Following the monitoring of the Budeasa Reservoir for the period 2018-2022, it is found that: the monitored physico-chemical parameters fall within the limits of NTPA 013, regarding the quality standards that surface waters used for drinking water must meet (Quality Categories A1 and A2); the monitored microbiological indicators fall within the limits of NTPA 013 (Quality Category A2), with the exception of July 2018, when the values of the Total and Fecal Coliforms indicators fell within the limits of Quality Category A3; the monitored microbiological indicators fall within the limits of NTPA 013, regarding the quality standards that surface waters used for drinking water must meet (Quality Category A2), with the exception of July 2018, when the values of the Total and Fecal Coliforms indicators fell within the limits of Quality Category A3.
