[Evaluation of iron, fluoride and iodine concentrations in underground water in some counties in Romania].

Aim: To compare the underground water mineral composition in iron, fluorine and iodine from different sources, with variable locations in Romania.

Methods: It is a lab study based on Hanna Instruments C99 colorimeter used for our tests, that follows the levels of mineral parameters from water samples from several underground water supplie sources from 10 different romanian counties.

Results: It were significant differences between sources from different counties, and also from different sources in the same county, regarding minerals levels in water and also comparing to admitted levels. The most various data were related to fluorine and iodine levels in water samples and risk of exposure by deficiency.

Conclusion: It is important to know the importance of supply water monitoring, to evaluate both the drinking water quality parameters and mineral composition, in order to estimate the influence on health status of long shut consumer population.
