Description

Li-Juan Xiao and co-authors hunt for what drives bad-tasting water in a large tropical reservoir in China. The earthy taste comes from geosmin, a compound made by cyanobacteria, and it plagues drinking water worldwide. In cooler lakes, temperature steers geosmin levels. Their 2024 paper tests what matters where the water stays warm all year.

Across a year of field data, geosmin ranged from undetectable to 856 nanograms per liter, and high levels showed up in nearly every month. One cyanobacterium, Dolichospermum circinale, stood out as the main producer, by both correlation and direct cell measures. No weather or water measure tracked geosmin directly. Instead, high total nitrogen explained the blooms of the producer, and so fed the taste events. The authors point water managers toward nitrogen control as the lever that matters in warm reservoirs.
