The rapid assessment tool for evaluating the impact of plastic waste on water bodies is a valuable approach for safeguarding human health, aquatic habitats, and other natural resources. This tool, based on the established protocols for assessing and monitoring floatable debris of the United State Environmental Protection Agency and the California Regional Water Quality Control Board’s rapid trash assessment methodology. The research group has refined this assessment tool to enhance user accessibility and practicality. The research results have determined six key assessment criteria. Each survey site using this tool receives a composite score from 6 to 54, reflecting the cumulative impact across all six criteria. The score provides a clear classification of the site's condition regarding plastic waste impact. In detail, Poor (6 – 18): Indicates severe impact from plastic waste, requiring immediate and significant intervention. Moderate (19 – 36): Reflects a moderate level of impact, suggesting that the site is affected but not critically, necessitating targeted mitigation efforts. Good (37 – 54): Shows minimal impact, suggesting effective control measures are in place and the site is relatively healthy with respect to plastic waste pollution. This method has also been tested in practice and shown to be effective when applied to assess the impact of plastic waste discharge in water bodies. The rapid assessment tool supports timely and informed actions to mitigate pollution, protect ecosystems, and improve water quality. The tool's adaptability and efficiency make it a crucial asset in the ongoing efforts to combat plastic waste pollution in various water bodies.
