Foreword
This Standard is drafted in accordance with the rules given in GB/T 1.1-2009.
This Standard replaces GB/T 14848-1993 “Quality standard for ground water”.
As compared with GB/T 14848-1993, in addition to editorial changes, the main
technical changes are as follows.
- The water quality index is increased from 39 items of GB/T 14848-1993 to
93 items, an increase of 54 items;
- With reference to GB 5749-2006 “Standards for drinking water quality”,
groundwater quality indices are classified into regular and non-regular
indices;
- The sensory traits and general chemical indices are increased from 17
items to 20 items, increasing the 3 indices of aluminum, sulfide, and sodium.
USE oxygen consumption to replace permanganate index. REVISE the 4
indices of total hardness, iron, manganese, and ammonia nitrogen;
- The index of inorganic compounds in toxicological indices is increased from
16 items to 20 items, increasing the 4 indices of boron, antimony, silver, and
thallium. REVISE the 11 indices of nitrite, iodide, mercury, arsenic,
cadmium, lead, beryllium, barium, nickel, cobalt, and molybdenum;
- The index of organic compounds in toxicological indices is increased from
2 items to 49 items, adding trichloromethane, carbon tetrachloride, 1,1,1-
trichloroethane, trichloroethylene, tetrachloroethylene, dichloromethane,
1,2-dichloroethane, 1,1,2-trichloroethane, 1,2-dichloropropane,
tribromomethane, vinyl chloride, 1,1-dichloroethylene, 1,2-dichloroethylene,

chlorothalonil, 2,4-D, chlorpyrifos and glyphosate. DDT and
hexachlorocyclohexane are replaced by DDT (total) and
hexachlorocyclohexane (total), respectively, and revised;
- The total α radioactivity in the radioactive index is revised;
- REVISE the relevant provisions of the comprehensive assessment of
groundwater quality.

quality, groundwater quality survey and monitoring, and groundwater quality
assessment, etc.
This Standard applies to groundwater quality survey, monitoring, assessment,
and management.
2 Normative references
The following documents are indispensable for the application of this document.

3 Terms and definitions
The following terms and definitions apply to this document.
3.1 Groundwater quality
A general term for the physical, chemical, and biological properties of
groundwater.
3.2 Regular indices
Indices which reflect the basic conditions of groundwater quality, including
sensory traits, general chemical indices, microbiological indices, common
toxicological indices, and radioactive indices.
4 Groundwater quality classification and indices
4.1 Groundwater quality classification
According to China’s groundwater quality status and human health risk, with
reference to drinking water, industrial, agricultural, and other water quality
requirements, according to the content level of each constituent (except pH), it
is classified into five classes.
4.2 Groundwater quality classification indices
The groundwater quality indices are classified into regular indices and non-
regular indices. The classification and limits are shown in Table 1 and Table 2
respectively.
5 Groundwater quality survey and monitoring
5.1 Groundwater quality shall be monitored regularly.
5.2 According to the dynamic changes of groundwater quality, regional
groundwater quality survey and assessment shall be carried out regularly.
5.3 Groundwater quality survey and monitoring indices are based on regular
indices.
5.4 The collection of groundwater samples shall be carried out in accordance
with relevant standards. The preservation and submission-for-inspection of
groundwater samples shall be carried out in accordance with Appendix A.
6 Groundwater quality assessment
6.1 Groundwater quality assessment shall be based on groundwater quality
testing data.
6.2 For the single-index assessment of groundwater quality, according to the
limit value of the index value, the groundwater quality class is determined.
When the index limits are the same, the superior shall prevail.
