ABSTRACT
Determination of chemical parameters in drinking waters is essential in the assessment of human health effects. The present study evaluates the chemical parameters (inorganic anions and metals) of twenty well-waters used as drinking water supply, in a rural area affected by several flood events from Timis-Bega area, Romania. In all analysed well water samples, the concentrations of fluorides and chlorides were below the maximum allowable concentrations (MAC) for drinking water established by European environmental legislation (Drinking water Directive 98/83/CE), nitrites and sulphates concentrations exceeded MAC in one sample, nitrates exceeded MAC in three samples. Phosphates concentrations exceeded threshold values for drinking water in the majority of the samples. Among the studied metals, Mn exceeded MAC in over 50% of the samples, Fe slightly exceeded MAC in only one sample, while Na, Cd, Cr, Cu, Ni and Zn concentrations did not exceeded the corresponding MACs. Despite the fact that several contaminants were below the corresponding thresholds, the high concentrations of Mn and phosphates may pose a risk to human health if the wells are used as drinking water source.
