Abstract: DOI: 10.24193/subbambientum.2020.1.03 Published Online: 2020-06-30 Published Print: 2020-06-30 pp. 43-57 VIEW PDF FULL PDF Baia Mare region is one of the most polluted areas from our country due to extraction and processing of ores with high content of Cd, Cu, Pb, Zn and precious metals. The main objectives of the present study were: to assess the groundwater quality by determine the physico-chemical parameters values, dissolved ions and heavy metal concentration and to evaluate if those groundwater sources can be used for irrigation and drinking purposes by calculating 10 specific quality indexes. A total of 70 groundwater samples were collected from 14 private wells and springs from Baia Mare and surrounding areas (November 2013 and December 2013, June 2014, September 2014 and December 2014). In situ a portable multiparameter WTW Inolab 320i respectively a portable turbidimeter were used to determine the physico-chemical parameters like: pH, ORP, EC, TDS, DO, salinity and turbidity. The dissolved ions (Li+, Na+, NH4+, K+, Mg2+, Ca2+, F-, Cl-, Br-, NO2-, NO3-, PO43-, SO42-) were analysed in laboratory by using an ion chromatograph IC DIONEX 1500. An atomic absorption spectrometer ZEENIT 700 was used to determine the heavy metals concentrations like: Cd, Fe, Mn, Ni, Pb and Zn. After calculating the specific quality indexes (WQI, MI, HPI, PI, SAR, % Na, SSP, MH, MR and KR), the obtained results indicated that the majority of the investigated water sources are not recommended for drinking and most of them are suitable to be used only like irrigation waters. Keywords: Baia Mare, mining area, groundwater, specific quality indexes, irrigation, drinking. |
