River Mouth Stations
Monitoring was carried out on estuaries, creeks, and diverse water bodies that feed into Manila Bay. The aim was to assess the pollution discharged by these outfalls into the bay.
Bathing Beaches Stations
To assess the contamination of pathogens at bathing beaches within the Manila Bay Region, 19 stations were monitored for total and fecal coliform counts.
Inland Stations
River systems in the Manila Bay Region (4a, 3, NCR) that discharge into Manila Bay were carefully monitored to assess their compliance with water quality criteria.
Offshore Stations
Throughout Manila Bay, nine stations were monitored to measure dissolved oxygen (DO), pH levels, salinity, temperature, conductivity, and total suspended solids.
