《Table 2 Field Testing Data of Groundwater in the Fangchenggang Area,Guangxi》
It is shown from the groundwater survey that the groundwater in the Area is obviously slightly acidic with a low pH value(Table 3).The average,minimal and maximum pH values of the groundwater in the wet seasons are 6.21,4.29 and 7.91 respectively.Moreover,the pH values of 46.11%,17.10%and 36.79%of the groundwater samples are 5.50–6.50,4.29–5.50and 6.50–7.91 respectively.The average,minimal and maximum pH values of the groundwater in the dry seasons are 5.84,4.12 and 7.97 respectively.Additionally,the pH values of 56.15%,30.77%and 13.08%of the groundwater samples are 5.50–6.50,4.12–5.50 and 6.50–7.97respectively.The groundwater in the Area is mainly slightly acidic with a pH value ranging from 5.50 to 6.50 as it is affected by rainfall,media in the aeration zone,hydrolysis of sulfurbearing minerals and tidal effects.
