///Groundwater samples were collected from the superficial and deep confined aquifers of Nantong to identify the water recharge source, hydrochemical characteristics and evolution mechanism of water chemistry. The total dissolved solids (TDS) of the superficial aquifer are higher than the deep aquifer in most areas, and it is higher in the coastal areas than in inland areas. Groundwater of the superficial aquifer in the central and western areas has a low TDS, but the TDS shows very high in some special areas near the coastal region. The analyses indicate that the local precipitation is the recharge source of superficial and deep aquifers. Dissolving salts of ancient marine strata is the major cause that increases the TDS of the deep confined groundwater in eastern coastal areas. The water quality of the deep aquifer in central and western areas is good as a whole, and the hydrochemical evolution is the natural water-rock interaction.
