Pollution and contamination of drinking water grow rapidly due to industrial growth and urbanization. They potentially cause severe problems to health, so the water quality management addresses both national and international action to assess and prevent the associated hazard. The quality of drinking water must be strictly controlled. The aim of the study was to determine the concentration of 210Po, 210Pb, 226Ra in drinking water. The occurrence of 210Po and 210Pb has been determined by a spontaneous deposition onto a nickel disc and the gross alpha activity has been measured. 226Ra has been measured after 30 days of storage in order to be sure that 222Rn in water samples reached secular equilibrium. Water samples were collected from a total of 17 sites, which serve 556,125 persons, in Galati and Vrancea areas of the East part of Romania. Samples were collected during March and April of 2015. The monitoring of drinking water samples indicated the presence of 210Po, 210Pb, 226Ra at a concentration ranging from 1.9 to 12.5 mBq L-1, 3.2 and 15.9 mBq L-1, 8.0 and 30.0 mBq L-1, respectively. These values were compared with the maximum level permitted, according to national legislation. The average annual committed effective dose from the intake of water ranged between 4.15x10-3 and 18.80x10-3 mSv y-1, for adults, which is lower than the recommended reference value of 0.1 mSv in water for human consumption according to the current EU legislation.
