The running water supplied in a centralized way from groundwater is of a worse quality than the surface water, shows a study carried out in all the districts of Moldova, including three municipalities and the Autonomous Territorial Unit of Gagauzia in July – September 2016, IPN reports.
Samples were mainly taken from the centralized system that supplies water to public institutions and from private individuals. In a press club meeting, Veronica Doni, one of the authors of the study, said 30 samples (30.6%) met the quality norms according to the examined physical-chemical parameters. In 66 of the samples, some of the physical-chemical parameters were higher than the allowed norms. Of the 75 samples analyzed according to microbiological parameters, 42 samples (56%) met the norms, while 33 samples (44%) didn’t meet the sanitary norms.
In the examined samples, the pH indicators and conductivity were within norms, but there were identified higher levels of fluorite, nitrates, boron, sodium, ferrum, etc.
The hardness of water was lower than the lowest allowed limit in 41 samples (48.8%) of the 84 examined. The lowest levels were recorded in Calarasi, Basarabeasca, Ceadar-Lunga, Falesti, Rascani, Edinet, and Donduseni. Water mineralization was higher than the allowed limit in 11 samples (13%) of the 84 examined. The highest values were recorded in Criuleni, Calarasi, Comrat, Taraclia, Sangerei, and Falesti.
The expert said that in the settlements with surface water sources, such as the Nistru and Prut Rivers, the samples mainly met the norms.
The study was made by East-Europe Foundation within the project “Harmonization of sanitary policies of the Republic of Moldova with those of the European Union”.
