Water is the most valuable natural resource and the protection of its quality is necessary. Water is a unique vital resource, without which life as we know it could not exist. Water is also a transport corridor and a very efficient climate regulator. The aim of this paper is to evaluate the effects of physicochemical indicators on water quality of Herăstrău Lake from Bucharest. Water samples were taken bi-monthly, from 2015 to 2020, 12 samples from each point and were monitoring 8 parameters, in order to design a monitoring network. Physicochemical analyzes of water samples are performed according to standardized methods. The analyzed parameters are: pH, EC, NTU, DO, BOD, COC-Mn, the concentration of nitrites and nitrates by spectrophotometry. Following the statistical analysis, a significant difference was found between the values of the studied parameters, and their correlation was verified by determining some regression functions. The results of the analyzes obtained can be used to generate thematic models on water quality monitoring and management to improve and protect biodiversity and quality of life.
