This study investigates how streams retain “memory” of nitrogen pollution from past land use. Using long-term data, it identifies a 3–5 year lag between nitrogen inputs and water quality impacts. It highlights the role of forests as natural filters and emphasizes managing both current and historical pollution to protect water supplies.

This research tackles harmful cyanobacteria blooms that threaten drinking water. Using ceramic membrane filtration, it prevents toxin release by retaining intact cells. Improved cleaning methods with eco-friendly chemicals enhance membrane efficiency and longevity. The work aims to ensure safe water treatment as climate change increases the frequency and severity of algal blooms.
