某大型铁钛矿区地下水环境现状调查与评价

根据该矿区重点部位地下水质分析数据，采用单因子标准指数法对该矿区地下水质进行了分析，显示除亚硝酸盐和高锰酸盐指数有超标现象外，该矿区地下水其余指标均能达到《地下水质量标准》中III类标准水质要求，说明该矿区内地下水环境质量总体状况较好。

Groundwater Environment Survey and Quality Evaluation for A Large Iron- titanium Mining Area

According to the analysis data of the groundwater state in a large-scale iron-titanium mining area, we adopt a single factor standard index method to study in detailed groundwater quality. Our study result shows that the other indexes are accordance with the Third-level standard in The Groundwater Quality Standards besides the nitrites and permanganate salts. Consequently, the groundwater environment quality in the mining area is generally in good condition.
