This results from inaccurate assessments of human activities, such as forest exploitation, on groundwater intake watersheds or insufficient monitoring frequency to understand their full impact on groundwater quality. This study involved a 3-year monthly monitoring of 18 groundwater intakes for drinking water supply, situated in areas with crystalline bedrocks, a temperate climate, and surrounded by forest exploitation. The quality of groundwater collected from alterites up to 15 m deep was evaluated over time. The correlation between the groundwater physico-chemical parameters (measured through 382 samples between March 2017 and December 2020) and the groundwater intakes’ environment - such as the geological and pedological context, land use, climate, and depth of drains - was investigated to understand their potential impact on groundwater quality. This study revealed a significant degradation in shallow groundwater quality (up to 5 m deep) concerning dissolved aluminum (concentration up to 2 mg L<sup>−1</sup>), which results from land use and is climate dependent. Indeed, dissolved aluminum concentrations in groundwater can be correlated with the pH of the upper soil horizons, which are mostly impacted by forestry practices, as well as with rainfall events. The results of this study highlight that by integrating efforts to preserve the soil and change forestry practices (<em>e.g.</em>, selective logging, avoiding rapid rotations), more efficient protection of groundwater quality can be achieved in the context of acidic soils present on crystalline bedrock.</p></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"26 ","pages":"Article 101256"},"PeriodicalIF":4.9,"publicationDate":"2024-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141539642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Present review is undertaken to highlight the process of breakdown of diverse groups of plastic products in soil, surface water, and groundwater under the influence of different factors (UV, light, heat, microbe, etc.), which are mobilized as MPs/NPs to the surface water, groundwater, air, soil, and living organisms by different natural and anthropogenic processes. Review also highlights a comprehensive overview of the methodology for sampling, characterization, and analysis for these minuscule plastic particles (PPs) in various environmental samples, encompassing surface/subsurface water, sediments, soils, and biological organisms. The collection, extraction, and characterization of MPs/NPs, typically employ filtration processes, wherein a known volume of water is passed through a fine mesh to capture MPs/NPs from water samples. Sediment/soil samples require sieving and density separation techniques to isolate PPs from the surrounding matrix. Biological samples require digestion steps to remove organic matter, leaving behind plastics for analysis. Fourier-transform infrared (FTIR) spectroscopy, Raman spectroscopy, and scanning electron microscopy (SEM) are commonly utilized to determine the polymer composition, size, shape, and surface characteristics of PPs. Quantification involves several approaches, visual counting, image analysis, and spectroscopic techniques. Abundance of MPs/NPs in the respective environmental samples (water, air, soil, etc.) can be determined by comparing the richness (i.e., number/mass) of plastics to the volume or weight of the original sample.

Remote sensing data indicates intensive structure lineaments in the middle-eastward part, spatially congruent with subsurface features deduced from radar satellites, facilitating hydraulic connections with the Nile water. The soil moisture index, land surface temperature, and salinity index in irrigated areas, reveal a strong association between in situ electrical conductivity values and satellite-derived spectral indices. The higher groundwater salinity in the middle eastern region coincided with high lineament density zones, and higher temperature zones, leading to increased rock water interaction that leads to groundwater salinization. The isotopic composition of the Quaternary aquifer ranges between −1.30 ‰ and +5.53 ‰ for δ<sup>18</sup>O, while δ<sup>2</sup>H ranges between −11.49 ‰ and +34.47 ‰.

Instead of the most commonly used criteria in groundwater literature such as lineament, stream order, recharge rate, and drainage density, this study employed alternative factors to challenge and validate the efficacy of the proposed methodology. The decision to omit certain criteria facilitated a more focused and manageable analysis, yet still delivered a robust evaluation of groundwater potential in the studied area. Moreover, this approach underscores the adaptability of the proposed methodology to accommodate varying sets of criteria, tailored according to the availability of data and specific research objectives. Additionally, the DEMATEL evaluation reveals new insights into subtle prioritization divergences, specifically between domain specialist opinions and analytical assessments of the criteria. The integration of fuzzy logic and causal relationship mapping through DEMATEL provides a comprehensive and robust foundation for groundwater potential modeling.</p></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"26 ","pages":"Article 101261"},"PeriodicalIF":4.9,"publicationDate":"2024-06-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141595617","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, non-carcinogenic effects on human health related to nitrate (NO<sub>3</sub><sup>−</sup>) concentrations were assessed. In terms of the measured parameters, four distinct clusters were identified Ca–HCO<sub>3</sub>, Na–HCO<sub>3</sub>, Na–SO<sub>4</sub>, and Na–SO<sub>4</sub>–Cl. Cluster 1 (68% of samples) had higher average pH while exhibiting lower average electrical conductivities (ECs), cations, and anions than the other clusters and had a lower average weighted arithmetic than the other clusters. 28.5%, 51.9%, 16.3%, 2.1%, and 1.2% of total water samples rated as excellent, good, poor, extremely poor, and undrinkable, respectively, implying that about 80.4% of the groundwater samples are potable. Multi-linear regression models based on pH and EC values can predict cation and anion concentrations in groundwater with high accuracy. The significance of the findings lies in their potential to facilitate the comprehension, modeling, and eventual forecasting of the fate of anions and cations in semi-arid and arid environments, as well as similar groundwaters, using common water characteristics. In order to lower the non-carcinogenic health risks to the local population, the appropriate actions should be taken. The majority of the region's agricultural areas have primary soil textures that are sandy and prone to NO<sub>3</sub><sup>−</sup> leaching. Therefore, in order to maintain the quality of the groundwater in the study region, excessive use of chemical and organic fertilizers should be avoided. These findings will contribute to understanding and safeguarding groundwater quality, while also informing management strategies in arid and semi-arid regions with similar environmental characteristics.</p></div>","PeriodicalId":37879,"journal":{"name":"Groundwater for Sustainable Development","volume":"26 ","pages":"Article 101255"},"PeriodicalIF":4.9,"publicationDate":"2024-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141539647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
