“…Consequently, a large number of people who are dependent on the river for their daily needs are found to be affected in the study area by water borne diseases such as, typhoid, diarrhoea, dysentery, cholera, malaria, jaundice, skin itching and infection. Moreover, poor water quality and lack of proper sanitation facility plays a vital role in spreading infectious diseases that are presently emerging and creating an immense public health problem (Kothari et al, 2021). According to WHO reports, 80% of all human illness in the developing countries is associated with polluted water (Witt, 1982).…”

Surface water serves most of the water requirements to sustain lives on earth. Of all fresh water on earth, only 1.2% is making up of surface water and the rest is confined in ice and ground. As the rivers provide for the significant sources of surface water, there is a need for river-based water resource management to meet global water quality challenge. Haora River that originated in the India’s north-eastern state of Tripura and meets ultimately with the Titas River in the Bangladesh carries a significant impact on life in and around the river both on the Indian side and Bangladesh side. Thus, study emphasizes the test of water quality of the river and corresponding impact therefor based on a detail explanation of the monitoring data obtained through published sources, laboratory analysis of samples and relevant field observations. ANOVA revealed year wise significant variations in physicochemical and biological properties of the river water tested except for pH. Abnormalities were mostly observed in the values of T, DO, BOD, PO4-P and FC. Water Quality Index (WQI) revealed water quality status of the river fall under the category of very poor to unfit, and require proper treatment before the water is being used for drinking and other domestic purposes. Adversities in the water are also found to be affecting the aquatic life and overall river ecosystem. Cause and effect analogy of these abnormalities were established for taking corrective measures. Existing statutory law to prevent and control such anomalies have been found lacking enforcement in the state of Tripura. The broad-based state level water policy to protect and improve water resources has also been found lacking in the state. The study recommends policy level interventions at the earliest considering the specific measures suggested in this study.

“…In that matter, correlation matrices were developed to evaluate the strength of the relationship among the studied parameters. In general, a high correlation indicated that two or more variables had a strong relationship with each other, while a weak correlation meant that the variables were hardly related [58]. Table 7 provides a summary of the interpretation of the correlation indices used in this study.…”

Textile industry production processes generate one of the most highly polluted wastewaters in the world. Unfortunately, the field is also challenged by the availability of relatively cheap and highly effective technologies for wastewater purification. The application of natural zeolite as a depth filter offers an alternative and potential approach for textile wastewater treatment. The performance of a depth filter treatment system can be deeply affected by the column depth and the characteristics of the wastewater to be treated. Regrettably, the information on the potential of these filter materials for the purification of textile wastewater is still scarce. Therefore, this study investigated the potential applicability of natural zeolite in terms of column depth for the treatment of textile wastewater. From the analysis results, it was observed that the filtration efficiencies were relatively low (6.1 to 13.7%) for some parameters such as total dissolved solids, electrical conductivity, chemical oxygen demand, and sodium chloride when the wastewater samples were subjected to the 0.5 m column depth. Relatively high efficiency of 82 and 93.8% was observed from color and total suspended solids, respectively, when the wastewater samples were subjected to the 0.5 m column depth. Generally, the 0.75 m column depth achieved removal efficiencies ranging from 52.3% to 97.5%, whereas the 1 m column depth achieved removal efficiencies ranging from 86.9% to 99.4%. The highest removal efficiency was achieved with a combination of total suspended solids and 1 m column depth (99.4%). In summary, the treatment approach was observed to be highly effective for the removal of total suspended solids, with a 93.8% removal efficiency when the wastewater was subjected to the 0.5 m column depth, 97.5% for 0.75 m column depth, and 99.4% for 1 m column depth. Moreover, up to 218.233 mg of color per g of the filter material was captured. The results derived in this study provide useful information towards the potential applicability of natural zeolite in the textile wastewater treatment field.

“…The concentration of chloride in the groundwater sample is directly related to the migration of wastewater into the aquifer. Likewise, it may be related to the inappropriate disposal of solid waste dumping in areas close to the water source [36,37]. The permissible limit for chloride in drinking water according to the WHO and Mexican regulations is 250 mg L −1 (Table 1).…”

“…Both nitrate and phosphate are an environmental concern as they are potential sources of nutrient enrichment in rivers, lakes, and wetlands. The presence of nitrates (0.0-3.17 mg L −1 ), ammonia (0-0.6 mg L −1 ), and phosphates (0.65-9.9 mg L −1 ) in groundwater are related to contamination by anthropogenic activities or infiltration of residual water [36][37][38], and this can cause variations in pH [39]. Agriculture is the primary source of nitrogen, while the origin of phosphate may be due to contamination by municipal wastewater, agriculture, anthropogenic activities, and the hydrological environment [40].…”

Sanitary landfills are considered one of the main sources of contamination of water resources due to the generation of leachate with a high content of dissolved organic matter (DOM), inorganic material, and toxic elements. This study aimed to determine the influence of leachate on the physicochemical quality and hydrogeochemical processes which determine the chemical composition of groundwater in an area near a municipal sanitary landfill site. In situ parameters (pH, temperature, electrical conductivity, dissolved oxygen, ORP), physicochemical parameters (HCO3−, PO43−, Cl−, NO3−, SO42−, NH4+, Ca2+, Mg2+, Na+, K+), and dissolved organic matter were analyzed. The content of dissolved organic matter (DOM) was determined by 3D fluorescence microscopy. The presence of Cl−, NO3−, NH4+, PO43−, BOD, and COD indicated the presence of contamination. The significant correlation between NO3− and PO43− ions (r = 0.940) and DOM of anthropogenic origin in the 3D fluorescence spectra confirm that its presence in the water is associated with the municipal landfill site in question. The type of water in the area is Mg-HCO3, with a tendency to Na-HCO3 and Na-SO+-Cl. The water-rock interaction process predominates in the chemical composition of water; however, significant correlations between Na+ and Ca2+ (r = 0.876), and between K+ and Mg2+ (r = 0.980) showed that an ion exchange process had taken place. Likewise, there is enrichment by HCO3− and SO42− ions due to the mineralization of the organic matter from the leachate. The groundwater quality that supplies the study area is being affected by leachate infiltration from the sanitary landfill.
