This study is meant to reveal the variety and role of the hydro-mineral resources from the southern sector of the Harghita Volcanic Mountain chain and emphasizes the sustainability of a territory with a poorly developed and diversified economy, which shows a high rate of unemployment and an aging process and a high value of immigration among the young generation This volcanic region of the Eastern Carpathians is justly considered a magnificent place with special powers. The numerous mineral water springs [2], [3] from this area prove the interest of the local communities to put to good use these natural resources [1], [9].
Within the region of Lăzărești parish 64 mineral water springs were identified [3], and only one of them is salt water spring [1], all the others have a different composition. Lăzărești settlement has the highest number of mineral water springs in this Neogen volcanic mountain chain – 64 [3], the area is being referred to as the ”Oasis” of mineral waters. The mineral waters and the moffetta from „Nyír” (birch) Baths if of international fame. The local population, especially the elders, confirm that a couple of decades ago there were more than one hundred mineral water spring in the area. Their disappearance is a direct consequence of agricultural development, and of the new techniques of cultivating crops and managing the pastures and meadows. The locals switched from manual labor and animal power to mechanized technologies. The technological development and human neglecting of the mineral water resources changed, although these were constantly used and played an essential role in the community's life. Besides these aspects we need to mention the rise of the phreatic waters and appearance of marshlands, erosion and the spread of seconadry vegetation.
For the analysis of the waters we proceeded with their chemical and mineral composition and their content of gases, respectively for their classification we chose only five springs. Three are widely knows and in use: „Büdös”, „Nagy”, „Cigány”
(Stinking, Big, Gypsy). A spring wish is known under the name of „Fürész” (Saw) (rehabilitated in 2017) which is often used by shepherds, being close the sheepfolds. The last one will be the salted - ”Sós” (Salted) - spring which is only known and sporadically used by the elders.
