Abstract

The water quality index (WQI) is a tool based on some physical, chemical and biological parameters, to directly qualify water in a single indexed value. The Jundiai River Basin, located in São Paulo State/Brazil, is an urbanized watershed and suffers from historical problems related to the quality of its water resources. This study aimed to analyze the WQI from 11 monitoring points along the Jundiai River Basin in two different periods (2010/2011) and (2020/2021). Secondary temporal data of water quality parameters were collected and the computed indexes were spatially interpolated. As results, improvements in water quality were observed in 4 sampling points, all of them located in the Jundiai River. Two, and two other sampling points, tributaries of the Jundiai River, has reduced in WQI category. The SARS-CoV-2 pandemic had a negative impact on field data collect for WQI measurement in Jundiai River Basin. This may affect the accuracy of WQI values for the period 2020/2021.

jundiai河流域水质指数(wqi)的时间分析及covid-19大流行对水系统监测的影响

水质指数(WQI)是基于一些物理、化学和生物参数，以单一指标值直接对水体进行定性的工具。Jundiai河流域位于巴西圣保罗州，是一个城市化的流域，其水资源质量存在历史问题。本研究对君迪亚河流域11个监测点2010/2011年和2020/2021年两个不同时期的WQI进行了分析。收集了水质参数的二次时间数据，并对计算指标进行了空间插值。结果表明，君迪亚河4个采样点水质均有改善。君殿河支流的两个采样点和另外两个采样点在WQI类别中有所减少。SARS-CoV-2大流行对君迪亚河流域WQI测量的现场数据采集产生了负面影响。这可能会影响2020/2021年WQI值的准确性。
