Introduction
With the acceleration of China's industrialization and the application of synthetic compounds, and various chemical components in groundwater are changing. The analytical technology has been continuously improved, and in order to meet the needs of investigation and evaluation, and to further coordinate with the upgraded GB 5749-2006 to promote exchange, a revision of GB/T 14848-1993 is necessary.
GB/T 14848-1993 is based on the background of groundwater formation and is adapted to the requirements for evaluation at that time. The new standard has been revised in conjunction with the upgraded GB 5749-2006, the research results of groundwater in the past 20 years by the Ministry of Land and Resources and the latest international research results. The number of indices has increased from 39 in GB/T 14848-1993 to 93, the 54 indices have been added; 20 index classification limits have been adjusted, and 19 index classification limits have been directly adopted. The comprehensive evaluation rules are reduced to make the standard more widely applicable.

4 Classification and Indices of Groundwater Quality
4.1 Classification of groundwater quality
Base on the groundwater quality and human health risk in China, it is divided into five classes according to the water quality requirements of drinking water, industrial, agricultural and other water, and the content of each component (except pH).
Class I: Groundwater has a low content of chemical components and is suitable for various purposes;
Class II: Groundwater has a relatively low content of chemical components and is suitable for various purposes;
Class III: Groundwater has a medium content of chemical components. Based on requirements of GB 5749-2006, it is mainly applicable to centralized drinking water sources and industrial and agricultural water;
Class IV: Groundwater has a high content of chemical components. Based on the requirements of agricultural and industrial water quality and the certain level of human health risk, it is applicable to agricultural water and some industrial water, and suitable for drinking water after proper treatment;
Class V: Groundwater should not be used as a drinking water source due to its high content of chemical components. Other purpose of water can be selected according to the purpose of use.
4.2 Indices for classification of groundwater quality
The indices for classification of groundwater quality are divided into regular indices and non-regular indices. The classification and limits are shown in Tables 1 and 2 respectively.

5 地下水質量調查與監測
5.1 地下水質量應定期監測。潛水監測頻率應不少于每年兩次(豐水期和枯水期各1次),承壓水監測頻率可以根據質量變化情況確定,宜每年1次。
5.2 依據地下水質量的動態變化,應定期開展區域性地下水質量調查評價。
5.3 地下水質量調查與監測指標以常規指標為主,為便于水化學分析結果的審核,應補充鉀、鈣、鎂、重碳酸根、碳酸根、游離二氧化碳指標;不同地區可在常規指標的基礎上,根據當地實際情況補充選定非常規指標進行調查與監測。
5.4 地下水樣品的采集參照相關標準執行,地下水樣品的保存和送檢按附錄A執行。
5.5 地下水質量檢測方法的選擇參見附錄B,使用前應按照GB/T 27025—2008中5.4的要求,進行有效確認和驗證。
6 地下水質量評價
6.1 地下水質量評價應以地下水質量檢測資料為基礎。
6.2 地下水質量單指標評價,按指標值所在的限值范圍確定地下水質量類別,指標限值相同時,從優不從劣。
示例:揮發性酚類Ⅰ、Ⅱ類限值均為0.001 mg/L,若質量分析結果為0.001 mg/L時,應定為Ⅰ類,不定為Ⅱ類。
6.3 地下水質量綜合評價,按單指標評價結果最差的類別確定,并指出最差類別的指標。
示例:某地下水樣氯化物含量400 mg/L,四氯乙烯含量350 μg/L,這兩個指標屬Ⅴ類,其余指標均低于Ⅴ類。則該地下水質量綜合類別定為Ⅴ類,Ⅴ類指標為氯離子和四氯乙烯。
