This study investigates the quality of ten different brands bottled water purchased from various stores across Romania, using a comprehensive analysis both physicochemical parameters and heavy metal content. The analyzed include pH, total dissolved solids (TDS), oxygen, turbidity, free chlorine, conductivity. Additionally, concentration metals was measured to assess compliance with current Romanian legislation international standards. Each brand subjected eight repetitions electroanalytical testing ensure accuracy consistency in results. Furthermore, statistical analysis, including descriptive Pearson correlation, Principal Component Analysis (PCA), employed identify key interdependencies among between identified metals. multifaceted approach offers deeper understanding overall available Romania highlights potential risks related contamination.
