武当山幅地下水水化学特征与水体污染评价

Wudang Mountain Range Groundwater Water Chemical Characteristics and Water Pollution Evaluation

在武当山幅1:5万水文地质调查基础上,系统采集区内地下水水样,结合研究区水文地质条件,根据实地调查取样统计和舒卡列夫分类法研究了区内地下水水化学特征。通过对水质结果统计分析,进行水体污染评价。依据《地表水环境质量标准》(GB3838-2002)统计区内采集地表水水样92个,检测结果显示,I类水点6个,II类水点23个,III类水点22个,IV类水点8个,V类水点33个;依据《地下水质量标准》(GB/T14818-2017)用单指标和综合评价方法,采集的31处地下水样品统计结果为II~III类水点17个、IV类水11个,V类水3个。在前述基础上根据各类水点的分布情况并结合地下水类型分布,对调查区地下水质量进行分区污染特征分析,武当幅地下水化学特征与水体污染评价为该区防治地下水污染,合理利用和保障饮用水安全具有十分重要的意义。

Based on the 1:50,000 hydrogeological survey of the Wudang Mountain area, groundwater samples were systematically collected in the area, and the groundwater chemical characteristics of the area were studied based on the field survey sampling statistics and Shukarev classification method, combined with the hydrogeological conditions of the study area. Through statistical analysis of water quality results, water pollution evaluation was carried out. Based on the Surface Water Environmental Quality Standard (GB3838-2002), 92 surface water samples were collected in the statistical area, and the test results showed that 6 water points of Class I, 23 water points of Class II, 22 water points of Class III, 8 water points of Class IV and 33 water points of Class V. Based on the Groundwater Quality Standard (GB/T14818-2017) with single index and comprehensive evaluation method, the collected 31 statistical results of the groundwater samples are 17 II~III water points, 11 IV water points and 3 V water points. On the basis of the aforementioned distribution of various types of water points and combined with the distribution of groundwater types, the ground-water quality of the survey area for zoning pollution characteristics analysis, Wudang magnitude of groundwater chemical characteristics and water pollution evaluation for the prevention and control of groundwater pollution in the area, rational use and to ensure the safety of drinking water is of great importance.
