As a result, the appropriateness was assessed in accordance with its composition and the global criteria for drinking water quality. This study aims to evaluate the quality of surface water of Brahmani River, Odisha, by adapting multivariate statistical approaches, namely Cluster Analysis (CA) and multi-criteria decision-making (MCDM) methods such as Simple Additive Weighting (SAW). Again, Geographical Information System (GIS) is employed to assess the drinking water's quality in relation to its application. Around 15 physicochemical parameters, gathered from seven distinct sites, following a period of 2022 till 2024. The results showed high values of EC, SO₄²⁻, NO₃⁻, PO₄³⁻, F⁻ and Ca²⁺, in three stations, while other studied parameters are within the permissible limits defined by WHO standards. The CA three distinct classifications of sites namely, low, medium, and high, based on how comparable the various physicochemical traits and pollutant levels were throughout the sampling locations. Sites H-(4–6) were included in cluster 1, site H-(3) and (7) classified under Cluster 2 and finally, H-(1–2) indicated as Cluster 3. Thus, as stated by CA, 42.86 % of tested water samples were fall into the group of good quality and about 57.14 % of examined locations resides in the poor category of water. The findings indicate which characteristics, as determined by the CA technique, were accountable for the alteration in the water quality and raise the potential of runoff from cities, farms, and industries. Subsequently, MCDM techniques has been implemented to facilitate rapid comprehension of surface water behavior and address problems with water resource management. The obtained SAW index ranges from 0.5 to 0.94. Here, H-(1), (2), and (7) grouped as highly polluted zone, and they seemed to be connected to runoff from farms and untreated industrial and municipal trash as well as local pollution sources. From this innovative study, it is found that even though the water is fit for drinking at 3 places, it is medium to highly suitable for human consumption. Therefore, there needs to be treated in some way before being used in addition to being protected against contamination. Most often, the findings indicate that appropriate management actions are important to restore the water quality of this catchment in order to support a robust and promising aquatic ecosystem. Additionally, the significance of this restoration for objective ecological policy and decision-making processes is underscored.</div></div>","PeriodicalId":100615,"journal":{"name":"HydroResearch","volume":"8 ","pages":"Pages 99-112"},"PeriodicalIF":0.0,"publicationDate":"2024-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142442784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is vital to assess climate change impacts on water resources to ensure resilience and sustainable management. The study assessed the resilience of 22 municipal water schemes using an indicator-based framework, How Tough is Wash (HTIW), across six domains: environment, infrastructure, community governance, water supply management, supply chains, and institutional support. The sites of municipal water supply were purposively selected based on specific criteria to include those water supply schemes which have been directly affected by flooding or are vulnerable to the impact of the flood. The resilience scores ranged from (6 to 7.5) for schemes with very low resilience, (7.5 to 10.5) for those classified as poor, and (10.6 to 16.5) for schemes considered moderately resilient. It was discovered that protective measures against the risk of flood were negligible. Community engagement governance and water supply management needed to be stronger. Local governments can pinpoint current advantages and disadvantages by utilizing these metrics and their impact on the public water supply's resilience and strategically allocate resources for optimal outcomes. Furthermore, the metrics that have been suggested simplify and unify the multiple dimensions of the elements, enabling decision-makers to optimize the measures.</div></div>","PeriodicalId":100615,"journal":{"name":"HydroResearch","volume":"8 ","pages":"Pages 89-98"},"PeriodicalIF":0.0,"publicationDate":"2024-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142424483","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

When humans are exposed to tritium, the primary concern is internal exposure through inhalation, ingestion, or absorption through the skin. The severity of the adverse health effects depends on the duration, amount, and route of exposure. Therefore, estimating the tritium levels in groundwater and the corresponding health risks within different age groups is essential. The annual effective dose is determined by considering several factors, including the concentration of tritium, the volume of water consumed, and the duration of exposure. The calculated annual effective doses were then compared to the safety limit as directed by international organizations. The estimated tritium concentration in the searched groundwater samples was significantly low, ranging from 0.014 to 0.114 Bq/L. The annual effective dose of tritium exposure for infants, children, and adults varies from 0.028 to 0.605 μSv/y and is within the safe limit recommended by the World Health Organization (WHO) and other international organizations. The lifetime cancer risk (LTCR) for the consumer in the searched areas was estimated for males and females based on the average lifetime. Mortality and morbidity rates varied slightly between males and females across samples due to differences in activity concentrations and locations. However, the estimated LTCR values were below the radiological cancer risk limit.
