This study analyzed 10-year (2015 - 2024) trends in water quality parameters and the Canadian Council of Ministers of the Environment Water Quality Index (CCME-WQI) across five provinces in Korea. The CCME-WQI analysis indicated that Gangwon-do maintained Fair to Good ratings with high stability, while Gyeonggi-do generally fell within the Marginal range. Chungcheong-do showed persistently low water quality, mostly within the Poor range. Jeolla-do exhibited mostly Poor-level quality, and Gyeongsang-do showed moderate variability with Fair-level quality overall. The nationwide average CCME-WQI was approximately 55.7, indicating a marginal water quality level overall. The coefficient of variation (CV) for CCME-WQI was consistently lower than that of individual parameters, supporting its robustness and representativeness as an integrated indicator. Correlation analysis revealed strong positive relationships between farmland ratio and nutrient-related indicators (e.g., COD<sub>Mn</sub>, T-P, SS), and significant negative correlations between CCME-WQI and these pollutants (e.g., SS: r = -0.96). Additionally, cumulative precipitation—particularly in July—showed stronger negative correlations with CCME-WQI (e.g., July: r = -0.80) than the farmland ratio (r = -0.69), suggesting that hydrological variability may exert a more immediate influence on water quality in agricultural watersheds than static land use patterns. These findings suggest that CCME-WQI is an effective tool for long-term water quality evaluation in agricultural watersheds influenced by non-point source pollution.
