Arsenic In Groundwater

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.

In recent years, in addition to water resources’ quantity, their quality has also received much attention. In this study, the quality of the urban water distribution network in northwestern Iran was evaluated using the water quality index (WQI) method. Then, some important trace elements were investigated, and finally, the health risk assessment was evaluated for both carcinogenic elements (Ni, Cd, Cr, Pb, and As) and non-carcinogenic elements (Ca, Mg, Na, K, F, NO3, and Cu) using carcinogenic risk (CR) and hazard quotient (HQ), respectively. In the present study, the WQI was calculated based on both World Health Organization (WHO) and Iranian drinking water standards. Comparing the results of these standards revealed that the WQI based on the Iranian standard was slightly higher. Regarding the calculated WQI for the study region, the status of water quality for drinking consumption is in the good water quality class (25 < WQI < 50). It was observed that Cu and Cd have the highest and lowest concentrations in all sampling points, respectively. Hazard Index (HI) results showed that the non-carcinogenic substances studied had a low risk for both adults and children (<1.0). However, the CR results showed that Ni, Cd, and As were above the desired level for both children and adults. The results of this study can be applied for efficient water management and human health protection programs in the study area.
