“…W a -WQI is used to assess the drinking water quality using the chosen physicochemical characteristics. Further, the relative weight (X i ) of each parameter is computed according to [13] and it is calculated from the equation: X i = H i / Σ H i , where X i represents relative weight and H i is the weight of each parameter. The quality rating scale (L i ) for each parameter was obtained from equation: L i = [V i /U i ] * 100, where L i referred as quality rating scale, U i stands for permissible standard and finally, V i illustrates about the monitored value of each variable, which is expressed in mg/l.…”

In this work, an effort has been made to comprehend the applicability of surface water in Brahmani Basin, Odisha for human consumption. Seven samples totalling 14 physicochemical parameters for the 2020–2023 period were examined and compared to the standard criteria advised by WHO methodologies to measure water quality using two indexing methods: Weighted Arithmetic (Wa) Water Quality Index (WQI) and Criteria Importance Through Intercriteria Correlation (Cr) WQI. As a result, Multiple-criteria decision making (MCDM) models, such as Evaluation Based on Distance from Average Solution (EDAS) were implemented to eliminate WQI index discrepancies, and they have been used to pinpoint the best spots along a river stretch where the water quality meets acceptable drinking criteria. The result of the WQI indicates that 57.14% (Wa-WQI & Cr-WQI) of surface water samples had poor drinking water quality. The area under study’s overall WQI, demonstrates that the water is fit for drinking (around 42.86% good water) except few localized pockets in location S-I, II and VII. Farmland, landfills, industrial effluent, residential sewage discharge, pesticides, garbage, habitations, and other potential sources of pollution can all contribute to poor water quality. Putting the above MCDM models into practice, it was clarified that S-I, II and VII was the most polluting area compared to most places. This was evident from the highest Wa-WQI and Cr-WQI values at these locations. The results revealed that this approach brings about noticeable results, which can support water resource planning and sustainable use in the research area.

A wide variety of bacteria are present in soil but in rhizospheric area, the majority of microbes helps plant in defending diseases and facilitate nutrient uptake. These microorganisms are supported by plants and they are known as plant growth-promoting rhizobacteria (PGPR). The PGPRs have the potential to replace chemical fertilizers in a way that is more advantageous for the environment. Fluoride (F) is one of the highly escalating, naturally present contaminants that can be hazardous for PGPRs because of its antibacterial capacity. The interactions of F with different bacterial species in groundwater systems are still not well understood. However, the interaction of PGPR with plants in the rhizosphere region reduces the detrimental effects of pollutants and increases plants’ ability to endure abiotic stress. Many studies reveal that PGPRs have developed F defense mechanisms, which include efflux pumps, Intracellular sequestration, enzyme modifications, enhanced DNA repair mechanism, detoxification enzymes, ion transporter/antiporters, F riboswitches, and genetic mutations. These resistance characteristics are frequently discovered by isolating PGPRs from high F-contaminated areas or by exposing cells to fluoride in laboratory conditions. Numerous studies have identified F-resistant microorganisms that possess additional F transporters and duplicates of the well-known targets of F. Plants are prone to F accumulation despite the soil’s low F content, which may negatively affect their growth and development. PGPRs can be used as efficient F bioremediators for the soil environment. Environmental biotechnology focuses on creating genetically modified rhizobacteria that can degrade F contaminants over time. The present review focuses on a thorough systemic analysis of contemporary biotechnological techniques, such as gene editing and manipulation methods, for improving plant-microbe interactions for F remediation and suggests the importance of PGPRs in improving soil health and reducing the detrimental effects of F toxicity. The most recent developments in the realm of microbial assistance in the treatment of F-contaminated environments are also highlighted.

“…Similarly, the exposure to extreme high (> 50 mg/L) nitrate for a longer period leads to adverse health risk, such as methemoglobinaemia, thyroid or cancer, hypertension, diabetes, spontaneous abortion, respiratory tract infection, and change in the immune system (Gupta et al 2000 ; Fewtrell 2004 ; Martínez et al 2017 ; Tokazhanov et al 2020 ). The interaction with fluoride-rich minerals such as fluorite, mica, amphibole, villiaumite, and topaz present in aquifer lithologies as well as the chemical weathering of volcanic rocks leads to F enrichment in the water bodies (Cronin et al 2000 ; Yadav et al 2021 ; Alarcón-Herrera et al 2020 ). Higher nitrate, however, is a direct consequence of fertilizers as about 60% of water bodies with elevated nitrate occur near the croplands (Singh and Craswell 2021 ).…”

Due to an increasing reduction of hydrological resources across Mexico and their growing contamination from global warming and anthropogenic activities, this study evaluated water from the perennial Lake Coatetelco (Ca–Mg–HCO3) in tropical central-southern Mexico and groundwater (Ca–Mg–HCO3 and Na–HCO3–Cl) from the surrounding wells for drinking as well as irrigation qualities. Comparison with the WHO guidelines and the estimated water quality indices (DWQI and IWQI) grouped almost all the samples collected after the warm season rainfall in excellent and good categories (DWQI < 100) for drinking, even though fluoride remained > 1.5 mg/L in 50% samples. Except for one groundwater sample, all showed > 25% permeability (classes I and II) in Donnen classification indicating their suitability for irrigation. USSL and Wilcox classifications, however, catalogued some in the high-salinity hazard group and some as doubtful for irrigating regular plants. Samples from about 53% wells were also in high and severe restriction categories of IWQI for the irrigation. Total Hazard Quotient Index (THQI) for estimating the non-carcinogenic risk (HQfluoride > 1) showed that at least one lake water sample and 53% of groundwater might expose the adult and child population to dental and skeletal fluorosis. This water quality assessment data posterior to the rainfall season could be useful as a baseline for both the short- and long-term monitoring in attention to the United Nation’s Sustainable Development Goal 6.
