INTRODUCTION

 Metro Manila is still faced with mounting garbage disposal problem.  Incineration is banned in the country but suitable and acceptable landfill sites are difficult to find.  Payatas dumpsite has been closed on and off, although a large amount of refuse is still present which undergoes spontaneous combustion generating air-borne particulate and gaseous pollutants  La Mesa reservoir is threatened with elevated risks from airborne pollutants from various sources such as Payatas (500 meters away )

INTRODUCTION

To determine the risk from the Payatas dumpsite several studies will be conducted that include: airborne pollutant sampling and analysis - inhalable particulates with sizes less than 10 micron - volatile organic compounds (VOCs) and aromatic hydrocarbons especially benzene laboratory aqueous simulation  atmospheric modeling

Project Mobilization T1 Air Sampling – a) Payatas dumpsite b) Ambient air T2 Analysis of Air Samples – a) Fine and coarse particulates b) Gaseous pollutants c) Elemental analysis T3 Aqueous Simulations T4 Receptor Modeling T6 Reservoir Dynamic Modeling Risk Assessment T7 Water Treatment Process Evaluation Conclusions and Recommendations T5 Air Dispersion Modeling
