“…Measurements of DBPs levels in drinking water have been carried out regularly worldwide (Abbas et al 2014;Furst et al 2019;O'Driscoll et al 2018;Yao et al 2019). In Iran, a number of studies (Ahmadi and Ramavandi, 2014;Alipour and Ghanbarnejad, 2014;Babaei et al 2015;Ghoochani et al 2016;Kalankesh et al 2019;Mohammadi et al 2019;Mohammadi et al 2016;Nadali et al 2019;Ramavandi and Asgari, 2012) have investigated THMs formation potential, THMs concentrations in tap drinking water and related health risks in different parts of the country. These studies found THMs levels ranging from 10 ppb to more than 100 ppb.…”

Trihalomethanes (THMs) are one of the most common classes of disinfection by-products. In this study. the temporo-spatial trends and health risks due to exposure to THMs in the Tabriz water distribution network were investigated. THMs series were analysed using gas chromatography equipped with electron capture detector. The non-carcinogenic and carcinogenic risks due to exposure to THMs were calculated using Monte Carlo simulations.Mean concentrations of THMs in January (winter) and June (summer) were 10.2 ± 9.3 µg/l and 252 ± 185.9 µg/l, respectively. More than 80% of THMs identified were bromodichloromethan.The mean values of lifetime cancer risks (LTCR) from THMs were calculated as 4.23E-06 and 2.38E-04 for winter and summer, respectively. This study showed that there were noticeable levels of THMs in Tabriz's distribution network water, especially in the centre of the city. Although non-carcinogenic risks from THMs were below permissible recommended levels, carcinogenic risks likely remain due to high levels of THMs in some locations.

“…These findings are similar to the studies in Gipuzkoa (Basque Country, Spain) [ [67] , [69] , [70] ]. The probable reason for the negative correlation is as follows: all-natural organic matter does not necessarily result in the formation of disinfectant by products [ [68] , [71] ]. Similarly, there was a significant negative correlation between the amount of turbidity and THM formation.…”

“…Groundwater has become the primary water source for industry and agriculture in the world, due to its extensive coverage area, large storage capacity, excellent water quality, stable flow, and strong resistance to external pollution factors [2][3][4][5][6][7]. The world's population has been growing exponentially in recent years, posing a significant threat to the quality of groundwater worldwide [8][9][10][11]. The occurrence of many serious water pollution incidents around the world has caused major environmental and health problems [12,13].…”

Groundwater pollution has emerged as a significant water crisis in various regions around the globe. Groundwater serves as a crucial source of water for human consumption and agricultural activities in the Sichuan Basin where groundwater quality has yet to be concentrated. A total of 41 groundwater samples were collected from domestic wells in Suining city of the Sichuan Basin, which were used for analyzing the hydrogeochemical processes and suitability for irrigation and drinking purposes. In the study area, groundwater samples belonged to the HCO3-Ca type. Hydrochemical compositions were dominated by carbonate and silicate mineral dissolution with positive cation exchange. Agricultural activities and urban sewage were the primary sources of NO3− pollution. The irrigation water quality index (IWQI) was calculated using electronic conductivity (EC), Na+, Cl−, HCO3−, and sodium adsorption ratio (SAR). The IWQI values showed that the suitability of groundwater irrigation was generally good and presented the decreasing trend southeastwardly. According to the entropy-weighted water quality index (EWQI), the groundwater quality for drinking purposes was generally good. However, there were some local areas with poor water quality concentrated in the southeast part. According to the human health risk (HHR) model, the groundwater was deemed safe for adults and children. However, for infants, the nitrate level in the groundwater remained high and posed potential health risks. The combined IWQI and EWQI evaluation served as a valuable reference for the utilization of the groundwater resource in the Sichuan Basin, as well as other comparable regions worldwide.
