Abstract

Groundwater quality situated under the intensive agriculture production of the Strumica region, Republic of North Macedonia is investigated. Carbonate rock watering plays a significant role in groundwater chemistry. Nitrate concentrations greater than 50 mg/l were observed in 14% of investigated samples with a maximum concentration of 284 mg/l (med 3 mg/l). Almost 33% of Mn levels were above the levels of public health concern (>50 µg/l). Arsenic was found in elevated concentrations (> 10 µg/l) in almost 35% of investigated groundwater samples and 16% had concentration greater than 50 µg/l (max 177 µg/l). It is assumed that the reductive dissolution is a major mechanism by which arsenic is released into the groundwater. Statistical analysis shows significant differences regarding NH4+, PO43-, Fe, Mn, As, Ba, Ti, and Zn concentrations between shallow and deep groundwater. Factor analysis revealed four significant factors. F1 (Cl-, SO42-, Na, K, and B) associate the most affected ions by rainwater leaching. F2 (HCO3-, Ca, As, and Mg) make an association between ions that arise from the hydrogeochemical reactions. F3 (NO3-, NO2-, Mg, and Cu) associate ions affected by the reduction processes while F5 (NH4+, PO43-, and Fe) associate ions which are related to the use of fertilizers.
