松滋市城区饮用水源地水质现状与保护

Drinking Water Source Water Quality in Songzi City:Status and Protection

以松滋市主要饮用水源地——松滋西河为对象,以近3年的水质监测数据为样本,参照国家或行业水质标准进行比较分析.结果表明:松滋西河水质,2011年、2012年综合评价类别为Ⅲ类;2013年综合评价为Ⅳ类,除去总磷,其它所检项目综合评价仍处于Ⅲ类,说明总磷超标.研究发现:松滋西河水源地水质总体上呈现逐年变差的趋势.因此,为了保护松滋西河水源地的水质安全,从严格水资源管理制度、环保执法监管、生态环境保护、水资源监测、提高水环境保护意识等方面提出了相应的建议.
