Groundwater Quality in Suha Basin(Northern Group of Eastern Carpathians)

Abstract:

The mountainous climate of Suha drainage basin manifests through important rainfall quantities, which despite their relatively reduced length ensure a rich and constant discharge of rivers. The study of groundwater and their quality has been conducted by analyzing three wells drilled in 1972. Observations thus sum up over 40 years, sufficient time for a correct evaluation of water resources. The three wells are located on Gemenea (F1), Suha (F2) and Negrileasa (F3) rivers. The wells depths are different (F1 - 11 m, F2 - 10.5 m and F3 - 4.25 m) and present a water table depth of 9.5 m at F1, 8.60 m for F2 and 2.87 m in F3 section. Ostra and Stulpicani townships are alimented with groundwater from the aquifer represented by Suha and its tributaries’ common floodplain. In order to analyze water quality, samples from Tarnicioara and Stulpicani sections have been used. All chemical parameters (pH, Ca, Mg, Na, K, Fe, Cr, Cu, Zn, Cl etc.) do not present exceeding of the maximum admissible concentration (MAC). The aquifer represented by gravels and sands is rich and contains good quality water. Water resources present in Suha basin can sustain alimentation with drinkable and industrial water in the conditions in which mining activities at Lesu Ursului have stopped. Keywords: groundwater supply, representative basin, chemistry, water body, pollution
