Untreated wasted drained into the Laguna de Bay, the largest lake in the Philippines, pollutes its water supply and endangers marine and human life.

1. The Laguna de Bay provides 50% of the freshwater fish requirements of metro Manila and surrounding provinces. The lake also serves as a source of major transportation, power generation, irrigation for farmland, and drinkable water for ~15 million inhabitants.

2. Although providing such significant resources to the population, the lake is also home to agricultural and industrial waste due to the lack of a proper sewage system.

3. The high nutrient load of nitrogen and iron due to agricultural waste resulted in algal blooms of the cyanobacteria Microcystis Aeruginosa that can cause fish die-off as well as release toxins that contaminate drinking water.

4. The waste water has also promoted the proliferation of Water Hyacinths as an invasive species. Water Hyacinths create dense mats that reduce light and oxygen, while also preventing thousands of fisherman from sailing out to fish.

5. The Clean Water Act of 2004 looked to protect the country's water from pollution, giving the Laguna Lake Development Authority(LLDA) power on the management of Laguna de Bay.

7. The LLDA had jurisdiction of the lakes from the 1980s onwards, and it only took resolute action in 2014-2015. Even with the Management and Development Plans(MDPs) approved by the agency to regulate waste and industry, the MDPSs remain unimplemented

6.Although the LLDA has succeeded in educating youth on the significance of Laguna de Bay and the dangers of pollution, it has failed in enforcing policies as hundred of industries violate the Clean Water Act.
