Special Issue Information

Dear Colleagues,

This Special Issue considers surface freshwater and groundwater as equally important parts of the same overall resource, with the goal being to integrate inter- and transdisciplinary research on freshwater quality under changing climate scenarios where droughts are becoming more frequent and severe. The increasing scarcity of precipitation is leading to decreased water levels and water quality in surface and groundwater bodies, leading to environmental, societal, political and economic changes that can affect global health. In lentic water bodies, droughts and warmer temperatures promote the occurrence of life-threatening events within local communities. Groundwater quality may be also greatly affected, namely in coastal regions where freshwater salinization may occur. Therefore, the preservation of freshwater quality is a crucial and urgent issue to resolve. In the era of the “knowledge-based” society, information is vital to increasing understanding and awareness on the impacts of climate change and to prepare society to find and implement ways to deal with those changes through collaborative solutions (with stakeholders, academia and policy makers).

Within the context of climate change, and geographically focusing on the Southern Europe regions, we welcome research papers and reviews regarding current topics on freshwater ecology, toxicity, hydrochemistry, monitoring approaches, but also societal aspects related to these concerning climate challenges. Ultimately, this Special Issue intends to establish a multidisciplinary standpoint in regard to how best to tackle freshwater quality issues.

In the face of current challenges related to climate change, maintaining the appropriate quality of freshwater becomes crucial. This study examined the effectiveness of removing heavy metals (Cu(II) and Co(II)) using Chlorella vulgaris biosorbents (dietary supplements in the form of powder). This study determined the parameters of the biosorbent (point of zero charge (PZC) analysis using scanning electron microscopy with back-scattered electron (SEM-BSE) and Fourier transform infrared spectroscopy (FT-IR) analysis). Batch tests were also performed to determine the kinetic constants and adsorption equilibrium of Cu(II) and Co(II) ions. Based on the conducted research, it was found that a pseudo-second-order equation describes the kinetics of the biosorption process. Among the studied adsorption isotherms, the Langmuir and Freundlich models fit best. The results indicate that single-layer adsorption took place and Chlorella vulgaris is a microporous adsorbent. The maximum sorption capacity in the single-component system for Cu(II) and Co(II) was 30.3 mg·g−1 and 9.0 mg·g−1, respectively. In contrast, in the binary system, it was 20.8 mg·g−1 and 19.6 mg·g−1 (extended Langmuir model) and 23.5 mg·g−1 and 19.6 mg·g−1 (Jain-Snoeyinka model). Chlorella vulgaris is an effective biosorbent for removing heavy metals from freshwater. This technology offers an ecological and economical solution for improving water quality, making it a promising alternative to traditional purification methods. Full article

The construction of retention reservoirs that cause permanent water damming is a complex subject and requires an interdisciplinary approach to environmental issues. The scope of the conducted study includes (1) a natural inventory of the area of Jagodno Reservoir in central Poland, which has been in operation for almost a decade, (2) a natural inventory of the area where a reservoir of similar size could potentially be built (Sarny, in southwestern Poland), (3) an assessment of the local community’s attitudes toward the operation or construction of individual facilities, (4) analysis and use of the obtained results to predict the local impact of Sarny Reservoir. The results of this study indicate areas where the impact of Jagodno Reservoir should be considered negative, neutral, or positive and what effect can be expected during the construction of Sarny Reservoir. One of the more significant results for Jagodno Reservoir, we should point out, is the appearance of a few waterfowl breeding at the site (4 species), a substantial expansion of the ichthyofauna population (from 9 to 24 species, which does not apply only to native species), a local loss of 91E0 habitat (willow riparian forests) and the appearance of one species of an invasive plant (Canadian goldenrod), a favorable impact on the water quality of the River Wiązownica (reduction in total and nitrate nitrogen loads by an average of 43.4% and 58.2%, respectively), and a positive assessment of the reservoir’s impact on the development of the region by the local community (19 out of 26 village leaders expressed positive opinions with no unambiguously negative votes).

Climate change may increase the vulnerability of aquifers to contamination through extreme precipitation and extended drought periods. Therefore, the understanding of groundwater ecosystem dynamics is crucial, with bacterial assemblages playing a major role in biogeochemical cycles. The present research describes a geospatial study targeting the bacterial community structure of groundwaters from the largest karst aquifer in Portugal (the Maciço Calcário Estremenho), integrating hydrogeochemical and bacterial diversity data. A total of 22 samples were analyzed from a set of 11 geographically sparsely distributed groundwater sources in dry vs. wet seasons. The 16S rRNA gene barcoding data revealed bacterial community variability across samples in space and time. The phylum Proteobacteria was dominant across all samples (from 44 to 92% of total sequence reads), mainly represented by the classes Alphaproteobacteria (orders Sphingomonadales, BD7–3, Rhizobiales and Rhodospirillales), Betaproteobacteria (orders Burkholderiales, Rhodocyclales, Nitrosomonadales), Gammaproteobacteria (orders Pseudomonadales, Xanthomonadales, Alteromonadales, Legionellales) and Deltaproteobacteria (orders Myxococcales, Spirobacillales). Variation in the bacterial community was primarily attributed to parameters such as redox conditions (DO, ORP), Fe, Mn, SO4, PO4, Sr and Cl, but also some minor and trace elements (Al, V, Cr, Cu, Pb). Our results provide novel insights into bacterial diversity in relation to groundwater hydrogeochemistry. The strong dominance of OTUs related to bacterial taxa associated with nitrification/denitrification also highlights a potentially important role of these assemblages on nutrients (nitrogen sources) and groundwater quality dynamics at this karstic aquifer system. Moreover, the integration of bacterial assemblages information is emphasized as central for water quality monitoring programs. Full article

This study investigates the prevalence of resistance and virulence genes in Klebsiella isolates from surface waters in Northern Portugal, within the broader context of freshwater quality challenges in Southern Europe. The aim of this research is to explain how Klebsiella dynamics, antibiotic resistance, and biofilm formation interact in surface waters. Antimicrobial susceptibility was examined using the Kirby–Bauer disk diffusion method against 11 antibiotics and screening for Extended-Spectrum Beta-Lactamase (ESBL) production using the double-disk synergy. PCR was employed to detect resistance and virulence genes, while biofilm production was assessed using the microplate method. Out of 77 water isolates, 33 Klebsiella (14 Klebsiella spp. and 19 K. pneumoniae strains) were isolated. ESBL production was observed in 36.8% of K. pneumoniae and 28.6% of Klebsiella spp. High resistance rates to blaCTX-U were observed in both. The papC gene was prevalent, signifying potential environmental risks. Biofilm production averaged 81.3% for K. pneumoniae and 86.9% for Klebsiella spp. These findings underscore the intricate interplay between Klebsiella’s dynamics and freshwater quality, with ESBL’s prevalence raising concerns about waterborne dissemination and public health implications. This work supports the need for vigilance of Klebsiella in surface waters in Southern Europe. Full article

Rainwater is a source of freshwater that affects the aquatic and terrestrial ecosystems, and consequently human health. Since potential toxic elements (PTEs) have been found in rainwater in Southern Europe, its quality should be evaluated. This review assesses the current knowledge of the quality of rainwater in Southern Europe concerning PTEs, as well as its impact on the environment and human health. The presence of PTEs in rainwater poses challenges and simultaneously an opportunity for innovation in environmental management, particularly in water management. Further monitoring of rainwater quality, research, and policy development are needed to ensure that rainwater remains a viable and safe water resource. The challenges of rainwater quality regarding PTEs and of rainwater harvesting as a measure of drought mitigation, as observed in Southern Europe, require investing in rainwater treatment technologies. The treatment of rainwater harvested in Southern Europe can reduce environmental and health risks posed by PTEs, while enhancing the region’s resilience to climate change and water scarcity.
