Waste loading analysis was done for the Maragondon river by Barangay Sapang IV-I in Ternate, Cavite using chemical hydrographic data and geographic information systems. Results show that Barangay Sapang contributes high nitrogen and phosphorus load coming from households and urban runoff created by low incidence of proper sewage treatments. Community maps were made utilizing GIS as a tool to establish specific sites where pollutants occur. It is recommended that the municipal government create effective programs to decrease waste load to the river since the latter is an important source of livelihood for the stakeholders
