Abstract
Abstract Groundwater is an important water resource used for drinking, domestic and agricultural activities in Akşehir and surroundings. However, intensive agricultural and human activities in the region adversely affect groundwater quality. In this study, 31 water samples were collected from wells. According to the Piper diagram, groundwater in the study area was in the Ca–Mg–HCO3 and Ca–HCO3 water facies. As a result, it is not appropriate to use groundwater as drinking water in the study area in terms of trace elements and pollutant analysis results of water samples compared to limit values determined by WHO and ITHASY drinking water guidelines. The arsenic concentration in groundwater was studied in detail. The origin and concentration of arsenic in groundwater is associated with agricultural activities and pesticides in the region. Accordingly, a health risk assessment was carried out for the use of groundwater in the study area as drinking water. The results for all samples analyzed indicate that the groundwater concerned was not suitable for drinking purposes because of arsenic concentrations which exceeded maximum acceptable levels.

Environmental pollution is one of the most important obstacles to the sustainable development of countries
The total number of 31 groundwater samples was collected in October 2018 and the sampling point coordinates were loaded into the Magellan eXplorist 600 Manual Global Positioning System (GPS)
The hydrogeochemical facies of groundwater in the study area was evaluated according to Piper ( ) using major cations (Ca, Mg, Na and K) and anions (HCO3, SO4 and Cl) in meq/L units
Summary
Environmental pollution is one of the most important obstacles to the sustainable development of countries. As in the whole world, is an extremely valuable, economic and strategic natural resource. 95% of domestic wastewater and 70% of industrial wastewater are discharged to receiving environments without. Groundwater is especially preferred as drinking water because it is less frequently polluted (Şener et al ). About half of the world’s drinking water is taken from groundwater aquifers (Li et al ). Groundwater quality and chemistry are controlled both by natural processes (weathering and soil erosion) and by anthropogenic inputs
