Oil spills are a major environmental catastrophe that poses significant threats to marine life and coastal communities. This study assesses the coastal water quality of a partially remediated oil spill site in Jasaan, Misamis Oriental. Water samples were collected from Kimaya, Luz Banzon, and Solana stations to analyze key physico-chemical parameters, including temperature, pH, salinity, nitrate, total suspended solids, biological oxygen demand, dissolved oxygen, and oil and grease using descriptive comparative research design. According to the findings, the water quality parameters remained within acceptable limits. However, salinity in Station 3 was lower on average and not normally distributed, likely due to local activities. Among all the parameters, only temperature did not significantly differ between stations. However, it stayed within the allowable limits for Class SC waters, as defined by DENR Administrative Order 2016-08. Successful cleanup activities were indicated by oil and grease concentrations that were continuously below the reporting limit (<1 mg/L). The water quality after cleanup has remained stable throughout time, ensuring that it is suitable for marine life and recreational activities. The study emphasizes the importance of community involvement, sustained enforcement policies, and long-term monitoring in maintaining water quality in areas affected by oil spills.
