Access to clean water and sanitation is a fundamental human right, yet millions of people worldwide, particularly in low- and middle-income countries, face affordability barriers. This study evaluates Brazil's new social tariff policy for water supply and sanitation, enacted through Law No. 14,898, which introduces a nationally mandated social tariff policy for water supply and sanitation, representing

The divergent transformation pathways of iopamidol (IPM) adsorbed on polyethersulfone microplastics (PES-MPs) during UV/chlorine (UV/Cl2) and UV/peracetic acid (UV/PAA) treatments were elucidated in this study. Molecular-level trade-offs between degradation efficiency and disinfection byproducts (DBPs) toxicity were unraveled through fourier-transform ion cyclotron resonance mass spectrometry (FT-ICR-MS)

The authors regret that the grant number U240202 under the National Natural Science Foundation of China, as listed in the Acknowledgments section, was incorrectly stated. The correct grant number is U2240202. The revised Acknowledgments section is as follows:

Understanding how historical flooding duration and contemporary extreme flooding events interact to affect the ecosystem processes is necessary to develop biochemical models and accurately predict ecological functions in the future. In this study, we focused on the nitrogen (N) removal processes of riparian ecosystems (i.e., denitrification and anammox rates), and simulated the short-term flooding

The present study offers a new method for analyzing the bioluminescence kinetics generated by the toxicity-triggered bioluminescent bacterial mutant strain TV1061, to detect and differentiate heavy metals in water samples. Specifically, as a proof-of-concept, copper and mercury were used, in single and binary mixtures, to induce the grpE heatshock promoter generating a measurable signal. The research

Environmental and water quality monitoring increasingly relies on high-frequency data streams from sensor networks, yet anomalies in these datasets can compromise their reliability. Here we introduce two novel unsupervised methods for anomaly detection in spatio-temporal sensor arrays specifically designed for highly structured datasets such as those obtained by networks of sensors in rivers. The first

Iron-based Chemically Enhanced Primary Treatment (Fe-CEPT) can efficiently concentrate phosphorus (P) from municipal wastewater into sludge; however, unfavorable P release efficiency impedes P recovery from Iron-based Chemically Enhanced Primary Sludge (Fe-CEPS). This study developed an electro-digester by applying controlled potentials to bio-electrodes. The electro-acclimated microorganisms on bio-electrodes
