Ten, many cities are up to 80 percent.In urban and vast rural area, underground water is often unique watering.
National 195 city testing results show that 97 percent urban groundwater receives different degrees of pollution, 4 percent
Ten urban groundwater severe contamination.16 pollution tendencies are aggravated in northern 17 provincial capitals, southern 40 provincial capitals
3 pollution tendencies are aggravated in city, and in some areas, underground water pollution has had resulted in serious harm, injured water supply security.
The wide variety of underground water pollution, is related to industrial pollution, agricultural pollution, domestic pollution, naturally mining industry pollution, dirt
The factors such as dye, groundwater mining.The method for the treatment of underground water pollution is numerous at present, and permeable reactive barrier is to develop rapidly in recent years
A kind of effective underground water pollution based technique for in-situ remediation.Permeable reactive barrier is one passive filled with Active reaction medium
