Revival of the historic Manila Bay.
Revival of the historic Manila Bay.
DENR Secretary Roy A. Cimatu said,
The strict implementation of Republic Act 9275 or the Philippine Clean Water Act of 2004 is the “key to addressing water quality issues and other environmental problems in the historic bay.”
DENR Goal: Reduce coliform level to less than 270 MPN/100ml less by December 2019.
The environment chief added the planned Manila Bay rehabilitation program will be strategic to oversee the implementation of the three-phase Manila Bay Action Plan.
PLAN: Implementation of the three-phase Manila Bay Action Plan.
- Phase 1 is cleanup and improvement of water quality improvement
- Phase 1 is set to begin this year. It will include the clean-up of esteros and waterways, reduction of the level of fecal coliform and toxic discharges from establishments, and provision of temporary sanitation facilities for informal settlers residing along the esteros and the Manila Bay shoreline. Solid waste management and planning for the relocation of the informal settlers will also be done.
- Phase 2 is rehabilitation, and;
- Phase 3, protection and sustainment.

Coliforms are a broad class of bacteria found in our environment, including the feces of man and other warm-blooded animals. The presence of coliform bacteria in drinking water may indicate a possible presence of harmful, disease-causing organisms.
Most Probable Number (MPN)
MPN is most commonly applied for quality testing of water i.e to ensure whether the water is safe or not in terms of bacteria present in it. A group of bacteria commonly referred as fecal coliforms act as an indicator for fecal contamination of water. The presence of very few fecal coliform bacteria would indicate that a water probably contains no disease‑causing organisms, while the presence of large numbers of fecal coliform bacteria would indicate a very high probability that the water could contain disease‑producing organisms making the water unsafe for consumption.

Fecal coliform level in Manila Bay is at 330 million MPN (most probable number) per 100 milliliters. The acceptable level for Class SB water is 100MPN/100 ml.
