| Groundwater Quality and Contamination Characteristics in the Hutuo River Plain Area, Hebei Province |
| As the main industrial, agricultural, and drinking water source in the Hutuo River alluvial plain area, Hebei Province, the groundwater has a direct bearing on the residents’ daily life. In order to investigate the groundwater quality under the influence of human activities in this area, the authors collected 482 groundwater samples for tests and analyses. The evaluation using the improved fuzzy mathematics evaluation method shows that the samples whose quality exceeds grade III account for 21.5% of the total samples, and they are mainly distributed in the industry concentration area and on both sides of the sewage disposal river. Furthermore, the water quality in the alluvial-proluvial fan axle area is even worse than that in the middle and rim areas. The factors that mainly affect the water quality are the inorganic matters such as the total dissolved solid, total hardness, iron, manganese, and nitrate nitrogen. The organic matters with high detection rate include chloroform, carbon tetrachloride, carbon dichloride, ortho-dichlorobenzene etc. Computation with EPI Suite software shows that the GUS value of the component with high detection rate is comparatively high and the value has high consistency. Based on an analysis of the chemical component detection and the exceeding-standard factors of the groundwater, the authors found that the primary hydrogeological environment and the effects of the human activities are the important factors leading to the detection and exceeding-standard phenomenon of the toxic metals, trichlorine, and organic matters. |
