Contamination of natural water resources by discharges from the industrial sector in the Philippines continues to be a significant problem. In 2007, Greenpeace launched the Water Patrol to document the impact of water pollution on local communities in the Philippines. Within the framework of this project, several industrial sites located around Laguna Lake were visited in July 2010. During these visits, samples of wastewater discharges into creeks and tributaries of Laguna Lake and corresponding sediment or soil samples were collected. The sites which were chosen for investigation in this study were those accommodating potentially polluting facilities in the area.

The selection of the facilities was based on the following criteria:

  • facility operations were thought to involve the use of toxic chemicals;
  • the facility discharged wastewater directly into Laguna Lake or one of its tributaries;
  • in some cases, the facility  had been previously identified by government agencies as a polluting industry and listed in the black or red lists by the Laguna Lake Development Authority or the Department of Environment and Natural Resources.
