Abstract

ABSTRACT Surface water quality in coastal regions may be degraded due to various pollution sources, including seawater intrusion, dependent on season and distance from the coastline. This study aimed to fractionate and quantify pollution sources affecting surface water quality in a coastal region of Vietnam. Between 2016 and 2020, 400 surface water samples were collected from 40 sites during dry and rainy seasons and analysed for 15 parameters. The results showed that four primary pollution sources – seawater intrusion, agricultural production, residential activities, and human activities impacting the hydrological system – may contribute to the degradation of water quality. Seawater intrusion contributed approximately 83.3% to the determination of water quality in dry seasons and 35.3% in rainy seasons. Water quality was more degraded in areas within 20 km of the coastline than in more distant areas. A management strategy should be developed and implemented to improve surface water quality for sustainable development.

越南沿海地区地表水系统的时空评估和污染源识别与量化

沿海地区的地表水水质可能受到包括海水入侵在内的各种污染源的影响，这取决于季节和距离海岸线的距离。本研究旨在对越南沿海地区影响地表水质量的污染源进行分类和量化。2016年至2020年期间，在旱季和雨季从40个地点收集了400个地表水样本，并对15个参数进行了分析。结果表明，海水入侵、农业生产、居民活动和影响水文系统的人类活动是导致水质退化的主要污染源。海水入侵对旱季水质的贡献率约为83.3%，对雨季的贡献率约为35.3%。距离海岸线20公里以内的地区水质恶化程度较远。应制定和执行一项管理战略，以改善地表水质量，促进可持续发展。
