Abstract
This study introduces an innovative approach to coastal water quality assessment by leveraging bioindicators, specifically fecal coliform (FC) and Enterococcus sp., to evaluate the impacts of domestic wastewater on coastal ecosystems. These bioindicators are shown to be effective in monitoring pollution and guiding targeted control strategies, offering a significant advancement over traditional methods. The research highlights the limitations of phytoplankton as indicators, due to their reduced sensitivity to water quality variations, underscoring the need for improved bioindicator selection. Coastal water quality is crucial for marine life and ecosystem health. While conventional physicochemical measurements are widely used, integrating biological indicators like fecal bacteria and phytoplankton can provide more nuanced insights into ecosystem health. This study assesses the reliability of these indicators by comparing their relationships with traditional water quality parameters across eight sampling stations, utilizing both in-situ and laboratory analyses. The results reveal a broad range of physicochemical parameters: temperature (30.60 – 31.67 ℃), pH (7.94 – 8.12), salinity (28.55 – 31.23 ppt), dissolved oxygen (3.56 – 5.44 mg/L), and others. Bioindicators varied, with FC and Enterococcus sp. showing significant correlations with turbidity, ammonia, and phosphate. Notably, FC was negatively correlated with nitrate, demonstrating its sensitivity to water quality changes. In contrast, phytoplankton exhibited lower sensitivity and fewer correlations with water quality variables. The Marine Water Quality Index indicated moderate pollution (49 to 73) at most stations, except Numbak, which showed poor quality. This study concludes that FC and Enterococcus sp. are reliable bioindicators for assessing coastal pollution impacts, while phytoplankton are less effective. This innovative integration of biological and physicochemical measurements enhances coastal pollution management and supports sustainable resource conservation.
