Summary: Mezquital Valley is the world's largest reuser of wastewater for agricultural irrigation, with small landholders identified as the main drivers of change. The threat of wastewater treatment to the status quo can be alleviated by building a functional learning community between academia and farmers, allowing for the development of sustainable water management strategies.

Summary: This article discusses the possibility of outbreaks of waterborne infectious diseases even in countries with extensive sanitation systems, and highlights the challenges in managing water resources in the near future. The inclusion of viral indicators such as somatic coliphages is suggested to assess health risks, as their concentrations in wastewater remain consistently high worldwide throughout the year and persist longer than bacterial indicators outside the gut.

Summary: This study examines the quality of drinking water in 20 ASADAS in Costa Rica. The results show that the concentrations of fecal coliforms and E. coli are higher in water samples from region 3. Rotavirus-positive samples are more frequently detected in drinking-water samples from regions 2 and 3 during the dry season. Additionally, somatic coliphages are significantly associated with diarrheal cases in the region.

Summary: This study evaluated the usefulness of FPH subgroups, PMMoV, and crAssphage as indicators of source-specific fecal contamination and viral inactivation. FPH subgroups, PMMoV, and crAssphage were associated with pig and human fecal contamination, and showed different behaviors in viral inactivation. FRNA phage genogroups, especially the GIV-FRNA phage, were highly inactivated during the warm months in Japan.

Summary: The objective of this study was to identify and relate any bedrock fracture traces and surface depressions to any surficial or geomorphologic processes currently underway as a result of irrigation. The study found that fractures in the Living Filter area have a predominant NE-SW trend, which correlates with the location of surface depressions. The study also observed a decrease in land area in the agricultural portion and an increase in land area in the forested portion of the site. These findings enhance the understanding of morphologic characteristics of forested and agricultural depressions in karst topography and can be applied to similar sites with bedrock fractures.

Summary: The effluents from fish farms are highly fertile for irrigation. This study aimed to evaluate the clogging rate of a drip irrigation system using effluent from a rainbow trout farm. Results showed that the clogging rate varied depending on the emitter type and discharge, with N4 showing the best performance and N12 and M8 showing the highest sensitivity to clogging. Overall, it is possible to use rainbow trout effluent in a drip irrigation system with pressure compensating emitters.

Summary: This study examined the feasibility of reusing treated wastewater from the Oasis of Ouargla for watering plants. The results showed that irrigation with purified wastewater had a negative impact on plant growth compared to well water. It is recommended to choose salt-tolerant crops and dilute the wastewater with less salty water.

Summary: This paper explores the adaptive reuse of urban open spaces from a perspective that goes beyond human beings. It emphasizes that dealing with heritage involves a continuous process of transformation, and that reuse is a practice that constantly adapts to mutations. The practice of adaptation involves different types of users and makers, including both human and non-human beings.

Summary: The study revealed that ferrous iron has a significant impact on perchlorate reduction, leading to a decrease in the rate of perchlorate reduction and accumulation of chlorate in the samples. On the other hand, ferric iron had a smaller effect on perchlorate degradation. Scanning electron microscopy showed that the presence of ferrous iron initiated the formation of an oxidized iron crust layer on the bacteria's surface, potentially affecting the enzymatic system involved in perchlorate reduction.

Summary: This study aimed to improve the design of stormwater biofiltration systems for the removal of micropollutants and understand the role of micropollutant-degrading bacteria. The addition of granulated activated carbon to the filter media significantly enhanced the removal of atrazine, a model micropollutant, and accelerated its degradation. The prototype biofiltration system showed the potential for sustainable microbial remediation alongside the removal of stormwater macropollutants without compromising the overall removal performance.

Summary: Greywater treatment systems can effectively reduce antibiotic-resistant genes in greywater. The composition of bacterial community remains stable after treatment, with Proteobacteria, Epsilonbacteraeota, and Bacteroidetes being the dominant phyla. Several clinically relevant bacteria were identified in the treated greywater.

Summary: This study investigated the effects of perchlorate and chlorate on aerobic RDX degradation. The results showed different responses of different strains to co-contaminants, with enhanced growth observed in strain YH1 and inhibition in strain T7. The study also found that nitrogen limitation might be the reason for the increase in xplA gene expression.

Summary: In this study, the genomic and metabolic ability of Stenotrophomonas strain SG1 to degrade TNT was investigated. The results showed that the addition of carbon sources accelerated the transformation rate of TNT, with citrate promoting the highest growth and transformation ratio. The research findings are important for basic research and practical applications in removing TNT from wastewater.

Summary: A crude oil spill in Israel's Negev Desert resulted in soil contamination and decreased soil hydrophobicity, posing a threat to plant survival. Researchers isolated and identified indigenous bacteria capable of producing biosurfactants and degrading hydrocarbons, and found that inoculating these bacteria into the contaminated soil significantly reduced hydrophobicity.

Summary: This study investigated the appearance of oil-degrading bacterial species in the soil of a hyperarid area in Israel that experienced a major oil spill. The dominant phyla in both contaminated and control soils were Proteobacteria and Actinobacteria. The contaminated soil contained bacterial species capable of degrading aromatic and aliphatic oil constituents. Phosphorus amendment significantly accelerated the biodegradation of crude oil under extremely arid conditions.

Summary: The reuse of household greywater is increasing globally, however, wastewater and greywater treatment processes are not fully effective in removing all contaminants. The dynamics between emerging micropollutants and antibiotic resistance genes in greywater treatment systems are complex. More studies are needed to understand the fate and transport of emerging micropollutants, antimicrobial-resistant bacteria, and antibiotic resistance genes in microbial communities and soil properties.

Summary: Extensive research has been conducted on ion exchange membrane bioreactors, specifically Donnan dialysis contactors, for the removal of trace oxyanions from contaminated water sources. A plug flow Donnan dialysis contactor has been found to significantly increase concentration compared to continuous stirred tank reactor contactors. These findings provide a basis for scaling up Donnan dialysis contactors in full-scale bioreactor setups.

Summary: Diaphorobacter strain DS2 degrades 3-nitrotoluene and 2-nitrotoluene via 3-nitrotoluene dioxygenase (3NTDO), but is not directly involved in the degradation of 2,4,6-trinitrotoluene (TNT). DS2 strain can grow using TNT as the sole carbon and nitrogen source. Ammonium chloride and succinate can enhance the degradation rate of TNT. TNT does not compete with 3NT degradation in the resting cell experiment.
