Philippines, Marilao, Meycauayan and Obando River System: Cleaning up with zeolite and probiotics filtering systems
A major hub for aquaculture, the Marilao, Meycauayan and Obando River System is also badly contaminated by untreated wastewater from used car battery recycling, precious metal refining shops, tanneries and more. Water samples reveal worrying levels of cadmium, copper and lead. A four-year project sponsored by HSBC and carried out by Blacksmith Institute for a Pure Earth is testing innovative water filtering in fishponds, enhancing monitoring of water quality, providing comprehensive training to the fishermen, and expanding education, advocacy and public outreach.
