Abstract: JAMUYOT, CARL JOSHUA N., MALATE, JAN PATRICK R., SASTRE, DENMAR AIDEN F. Impact Assessment of Water Pollution on Shellfish Culture in Timalan River Watershed, Cavite, Philippines. Undergraduate Thesis Bachelor of Science in Environmental Science. Cavite State University Main Campus June 2022. Thesis Adviser: Prof. Noel A. Sedigo. This study was conducted from April to June 2022. The study aimed to: 1. Assess the level of water pollution in Timalan River Watershed in terms of ph, BOD, DO, Total Coliform, TSS and Water Temperature: 2. Determine the sources of pollution in Timalan river; 3. Identify the extent of shellfish culture in the river; 4. Identify the issues and problems affecting shellfish farmers in TRW; and 5. Recommend mitigation measures to prevent or reduce the impacts of water pollution on shellfish culture in the river. Mixed combined qualitative and quantitative approaches were used in the design of the study that included water sampling and water quality analysis, GIS and survey interview using a questionnaire. The results of water quality analysis from the three sampling sites were used to determine the level of water pollution in the river. The highest Total Coliform was obtained in Sabang river with 1.6million ppm. The agricultural manures and residential wastewater are the primary causes of increase in coliform level on TRW (Figure 9). The BOD, TSS, pH, and water temperature obtained from the three sampling sites were in normal condition. The lowest Dissolved Oxygen was obtained in Sabang river with 1.10mg/L. Most of the participants were 18 to 68 years old. Talaba farmers in Timalan Balsahan consisted of two groups, namely: Samahan ng Magtatalaba sa Sitio Lontoc and Samahan Ng Magtatalaba sa Tramo Tabing Ilog. The talaba farmers had many issues and problems that affected the shellfish culture in TRW. Majority reported that the water pollution was due to industrial, agriculture, residential wastewaters, unregistered poultries and piggeries, and lack of sewages treatment. After assessing the issues and problems, a mitigation matrix was created to prevent and reduce the water pollution in TRW.
