Abstract:
In order to determine the current situation of shallow groundwater environment in Tangshan plain area, samples of shallow groundwater were collected and analyzed. The results showed that hydrochemical type of shallow groundwater in Tangshan plain area has apparent zonation characteristics and the total dissolved solid (TDS) and hardness increase gradually from north to south. The TDS, hardness and concentrations of manganese, nitrate-nitrogen, fluoride, nitrite, and ammonia nitrogen were above those defined in the “National Hygienic Standard of Living Water”, and more attention should be paid to the toxic and harmful heavy metals, especially arsenic and hexavalent chrome. It suggested that river pollution, industrial pollution, and agricultural production are the main reasons to cause the deterioration of groundwater quality.
