Recalculating Water Treatment Plants' Nitrogen Impact
Nitrogen compounds in the runoff from wastewater treatment plants can feed microbes in nearby ocean ecosystems, fueling oxygen-depleted dead zones and toxic algal blooms. A new study of how the runoff's chemistry changes as it moves toward the ocean (Environ. Sci. Technol. DOI: 10.1021/es101115g) suggests that plants may release more microbe-friendly nitrogen than researchers previously thought.
