Correction: Dilpazeer et al. A Comprehensive Review of the Latest Advancements in Controlling Arsenic Contaminants in Groundwater. Water 2023, 15, 478

There were some errors in the original publication [1]. The authors forgot to seek copyright permission for Figure 1 from the publisher. All of the authors wish to remove Figure 1 from the main text and insert reference [40] in the paragraph 2 of Introduction Section to keep the original references order unchanged. The order and citations of the rest Figures also have been changed accordingly to make them appeared in numerical order.

A correction has been made to Introduction, Paragraph 2:

According to the World Health Organization (WHO), the permissible limit for arsenic is 10 μg/L, but the review of the literature showed arsenic concentrations higher than the permissible limit in many countries including Bangladesh [28], Iran [29], Pakistan [15,30], Mexico [31,32], Saudi Arabia [33], China (Yangtze River basin, Han River) [34], Latin America [35], the USA [36], and Ethiopia [37]. Asia is at the highest risk of drinking arsenic-contaminated water [38]. To reduce the treatment costs of diseases caused by arsenic exposure, Dutch water companies aim to reduce arsenic concentration up to <1 μg/L, a far lower level compared with the WHO’s permissible limit [39]. Groundwater in Bangladesh contains high arsenic concentrations, far higher than the permissible limit, which is 50 μg/L [28]. In Bam, southeastern Iran, arsenic concentration in groundwater ranges from 9.26 μg/L to 14.65 μg/L, while exposure to arsenic through ingestion is causing more diseases than the dermal route [29]. According to [31], 45% of the water samples in five zones of the metropolitan area of San Luis Potosí, Mexico showed an arsenic concentration above the WHO guidelines. A study carried out by [32] in which 44 groundwater samples were taken from two areas of the northeastern part of the province of La Pampa, Argentina showed arsenic concentrations ranging from 5.9 to 535.1 μg/L and from 17.5 to 248.4 μg/L for both sites. Podgorski and Berg reviewed the global threat of arsenic in groundwater and concluded that globally 13 regions are highly contaminated with groundwater arsenic [40]. Arsenic concentrations were projected on a map in the range of <10 μg/L, 10–50 μg/L, and >50 μg/L. Arsenic concentrations in different countries and their sources are presented in Table 1.
