| Abstract: | This article aims at finding out the deficiencies of the traditional washing wells and sampling methods,and offering more scientific basis for the late groundwater management by replacing it with a new method.By analyzing the domestic and international researches,the paper describes some shortcomings of the traditional process of washing wells and sampling(take washing well with submersible pump and sampling with bucket or Baylor for examples) and introduces a method not seen in domestic literatures—low-flow rate.The taken samples with new method have more obvious advantages in terms of representation and the obtained data are more accurate. |

| Keywords: | traditional washing well and sampling turbidity aeration filtration washing well and sampling with a low-flow rate |
