Researches of the nitrite/nitrate presence and other chemical compounds in some water sources from rural area of Neamţ county.
Water is one of the main dietary components and his quality may be influenced the health status of the population.


METHODS
We investigated the water quality (by ten chemical parameters) delivered to the rural population (Neamţ district), from the public water supply systems (n=10) with ground water sources and 60 well waters in same area. For determinations of the investigated chemical compounds, spectrophotometric, complexonometric and volumetric methods were performed. Statistical analysis was applied to analyze of data.


RESULTS
The regression analysis between nitrate-organic matters, nitrite-chlorides, nitrate-total hardness shows strong negative and positive relationships as r = 0.7631, r = 0.7252, r = -0.777, and very low correlations between other chemical parameters.


CONCLUSIONS
The results revealed that chemical parameters ranged between the admissible limits for drinking water.
