In the current research, the impact of the COVID-19 lockdown period on groundwater quality of Lower Meriç Plain (Thrace Region of Türkiye) was evaluated. Some significant nutrient characteristics (NO, NO, and PO), salinity characteristics (EC, TDS, and salinity), and physical characteristics (temperature, DO, pH, and turbidity) were investigated in groundwater samples collected from 45 sampling points in pre-lockdown and lockdown periods. Water quality index (WQI) and nutrient pollution index (NPI), Pearson correlation index (PCI), cluster analysis (CA), one-way ANOVA test (OWAT), and factor analysis (FA) were applied to assess ecological risk. Excluding recorded statistical differences in temperature and DO due to climatic conditions (p < 0.05), levels of all the investigated water quality parameters show no statistically significant differences and no significant reduction in pollutants measured in the lockdown period. On the contrary, the WQI and NPI scores have increased between the rates of 4.76-27.10% during the lockdown period. In the lockdown period, although the reduction of industry or limited production of many industrial facilities reduced the inorganic contaminant releases to the environment, ongoing agricultural activities and domestic wastes caused to prevent the reduction of organic pollutants in groundwater of the region during the lockdown period.
在当前的研究中，评估了 COVID-19 封锁期间对下梅里西平原（土耳其色雷斯地区）地下水质量的影响。在封锁期和封锁期之前，从 45 个采样点采集地下水样本，研究了一些重要的营养特性（NO₃、NO₂和 PO₄）、盐度特性（EC、TDS 和盐度）和物理特性（温度、DO、pH 和浊度）。应用水质指数 (WQI) 和营养污染指数 (NPI)、皮尔逊相关指数 (PCI)、聚类分析 (CA)、单因素方差分析 (OWAT) 和因子分析 (FA) 来评估生态风险。排除由于气候条件记录的温度和 DO 的统计差异（p<0.05），所有调查水质参数的水平在封锁期间没有表现出统计学上的显著差异，也没有检测到污染物的显著减少。相反，封锁期间 WQI 和 NPI 得分增加了 4.76-27.10%。在封锁期间，尽管许多工业设施的工业活动减少或生产受限，减少了无机污染物向环境的释放，但持续的农业活动和生活污水的排放导致该地区地下水的有机污染物在封锁期间没有减少。
