“…Evaluation of groundwater quality is an essential tool in realizing the role of anthropogenic influences on the groundwater system (Gorgij et al, 2019). Furthermore, BOX-PCR is the most frequently used technique to evaluate the origin of a given microbial type (Safiulah et al, 2009;Galloway & Levett, 2010).…”

M UNICIPAL sewage, septic tanks, fertilizers, animal feedlots and irrigation wastewater are the common sources of groundwater pollution in rural areas. Sedimentation pools of wastewater treatment plants are possibly suggested to be another source of pollution. Two wastewater treatment plants located at Qalyubia governorate named Qalyub (QWTP) and Shubra Al-khayma (SHWTP) were selected to carry out the present study; two samples from influent and effluent were collected seasonally from both plants. Furthermore, 6 groundwater samples were collected from nearby rural houses of both plants. The physicochemical and microbiological properties were evaluated for all samples. Moreover, Box-PCR for 12 strains isolated from wastewater and groundwater at Qalyub district was carried out. Water quality assessment studies proven that the effectiveness of the two wastewater treatment plants under investigation is questionable, especially QWTP. The percentages of removing of TSS, COD, BOD, ammonia, total coliform and fecal coliform counts were 87, 74, 88, 66, 94 and 89%, respectively, for QWTP, and 85, 89, 93, 86, 94 and 83%, respectively, for SHWTP. The groundwater at Qalyub district was contaminated with Mn, Fe, ammonia, BOD, coliform bacteria, fecal streptococci, E. coli, Aerumonas hydrophilla and Pseudomonas aeruginosea, while the groundwater at Shubra Al-khayma district was contaminated with Mn, coliform bacteria, fecal streptococci and P. aeruginosea. Microbial and chemical evaluation of groundwater, as well as, Box-PCR results proven that, the contamination of the tested groundwater might be of other source than water treatment plants.

“…Santos et al [ 34 ] suggest that combining TOPSIS with other MCDM methods may be more effective and more flexible to solve problems. Gorgij et al [ 35 ] used the entropy-TOPSIS method to rank the quality of groundwater resources. Jena et al [ 36 ] integrated ANN-cross-validation and AHP-TOPSIS model to improve earthquake risk assessment.…”

In recent years, in the context of China’s continuous medical and health reforms, the health status of Chinese women and children has been significantly improved through the continuous efforts of staff at all levels of maternal and child health care institutions. Many indicators in maternal health care have improved significantly, but the speed and magnitude of changes have varied. The purpose of this study is to evaluate the dynamic changes in China’s maternal health status from 2004 to 2018, in order to determine whether China’s medical and health reform measures in recent years have improved maternal health. A total of 6 evaluation indicators from the data of China Health Statistics Yearbook 2019 were selected. Then, based on the multi-criteria decision-making (MCDA) methodology, the entropy weighted technique for order preference by similarity to an ideal solution (TOPSIS), entropy weighted rank-sum ratio (RSR) method and the fuzzy comprehensive evaluation were employed in this study. In addition, sensitivity analysis was engaged to validate the stability and accuracy of the achieved results. The study results shows the ranking values of various methods were not exactly the same, but the overall trend was consistent. Overall, the maternal health care in China improved from 2004 to 2018 year by year, of which the top four were ranked from 2015 to 2018, and relatively poor from 2004 to 2006. This means that the policies and measures implemented in China’s medical and health reform in the past few decades have effectively promoted China’s maternal health care, and this will also provide a theoretical basis for future decisions to promote maternal health care.

“…In recent years, the groundwater aquifers in the study area have been faced with over-extraction due to overpopulation, industrialization, and overuse of fertilizers. Since the study area is located in the vicinity of the hypersaline region of the Urmia Lake where there is an imbalance between precipitation and evaporation, its water consumption is completely dependent on groundwater resources (Gorgij et al 2019). For example, in the Azarshahr plane, 100% of the water for drinking, domestic, and industrial purposes and 80% of the water for agricultural purposes are supplied by the groundwater resources (Gorgij et al 2017).…”

Spatial and temporal assessment of groundwater quality and hydrogeochemical processes in Urmia Lake Basin, Iran

et al. 2021

The evaluation of groundwater quality and geochemistry have an important role in the management of water resources in arid and semi-arid regions. In the present study, the spatio-temporal assessment of groundwater quality and hydrogeochemical processes, as well as, statistical analyses in the Azarshahr and Ajabshir planes located in the Urmia Lake basin were investigated. The results revealed that within six years (from 2014 to 2019), the value of total hardness was higher than the permissible level and the quality of groundwater for drinking was very hard and fresh in both planes. In 2019, 84 and 67% of the samples fell within the range of good to poor groundwater quality in the Azarshahr and Ajabshir planes, respectively. The temporal assessment with the help of water quality index values for both planes revealed a good groundwater quality for the Azarshahr plane and a good to poor groundwater quality for the Ajabshir plane. However, deterioration of water quality was observed in both planes from 2014 to 2019. The level of water quality for irrigation was better in the Azarshahr plane than in the Ajabshir plane, due to the presence of fewer salty sites. In addition, Ca–Mg–HCO3 and rock dominance were identified as hydrochemical facies and controlling factor in the groundwater of both planes, respectively. Multivariate statistical analyses indicated both natural and anthropogenic sources (such as weathering, fertilizers, and wastewater) for hydrochemical parameters. It was suggested to develop a comprehensive regulation to control the entry of pollutants into the groundwater of the study area.
