The Study of Water Quality of Several Local Sources

Aim: The aim of this study is to analyze the water quality of several local sources from the Toplița-Deda region, as well as from the Gheorgheni basin, in order to inform the population about the water quality and about the importance of the drinking water control.
Method: Repeated water samples were collected from a total number of 41 sources in the two studied regions during 2010. A multiparametric colorimeter, Hanna Instruments C99 was used to determine certain physical and chemical parameters. A number of current and specific microbiological analyses were also carried out.
Results: The average values and the percentage of the positive samples with values above permitted limits were calculated. The highest accepted levels were based on Law no. 458/2002 regarding drinkable water quality. Among the mineral indicators iron exceeded the limit in 18.18% and water samples were poor in fluoride (83.65%) and in iodine (98.18%). A small percentage of sources (3.63%) indicated pollution, 10.9% had high nitrate level. Analyzing the microbiological content, our water samples were within the drinkability limits required by law.
Conclusion: Our study emphasizes the importance of monitoring water supplies, the awareness of the water quality according to mineral composition, pollution estimation and microbiological characteristics in order to prevent the unexpected influence on the health status of the consumer population.
