The Marilao River in Bulacan province has been biologically dead since 1989. It is a major tributary of Manila Bay and was responsible for about a third of the organic matter going into the historic natural harbor in the country’s capital, next only to Pasig River. Several administrations attempted to revive the Marilao River, but efforts have so far failed.

PCIJ reporting fellows Annie Ruth Sabangan and Bernard Testa took these photographs as they sailed into Marilao River to hunt for the drain pipes of chicken dressing and rendering plants that release wastewater into the river.
