Abstract By analysis on 21 groups of shallow groundwater samples taken from Jiansanjiang Farm in Sanjiang Plain, they are classified into three types by water quality, including 1 group of Type Ⅲ, 11 groups of Type Ⅳ and 9 groups of Type Ⅴ. Organic pollutants from 13 groups of samples are detected, but not exceed standard. Generally, the groundwater in paddy field of Jiansanjiang farm is seriously polluted, with most groundwater belonging to Ⅳ and Ⅴ types, not suitable for drinking. Affected by original geological environment, part of groundwater contains overproof Fe and Mn. The reason for exceeding volatile phenol and Pb is yet to be identified. Organochlorine pesticide is not detected, indicating that this type of pesticide residue in shallow groundwater is not much. NO2-, ammonia nitrogen and other elements as well are seriously exceeded, showing that large amount of fertilizer applied in agricultural production significantly impacts the quality of shallow groundwater.
