2021年秦皇岛市集中式饮用水源地环境质量现状分析

Analysis on Environmental Quality Status of Centralized Drinking Water Sources in Qinhuangdao City in 2021

以2020—2021年集中式饮用水源地水质监测为基础,本文分析了秦皇岛市2021年饮用水源地环境质量现状。结果表明,除后孟营水源地水质类别为Ⅳ类外,其他水源地水质类别均满足地表水或地下水的Ⅲ类水质要求。所有水源地均存在单因子评价结果变差的情况。饮用水源地水质有变差的潜在风险,需要加强关注和保护。

Based on the water quality monitoring of centralized drinking water sources from 2020 to 2021,this paper analyzes the environmental quality status of drinking water sources in Qinhuangdao City in 2021.The results show that the water quality of Houmengying water source is classified as Class Ⅳ,in addition,the water quality of other water sources meets the requirements of Class Ⅲ for surface water or groundwater.The single factor assessment results of all water sources are worse.There is a potential risk that the water quality of drinking water sources will become worse,which requires more attention and protection.
