Spatial variability and distribution of fluorine contents in shallow groundwater in the Fengpei area,Jiangsu

Spatial variability and distribution of fluorine content in shallow groundwater in the Fengpei area are examined with the method of geostatistics based on field survey and sampling analysis data. The results showed that almost 62. 75% of the examined wells exhibit fluorine concentrations higher than the national standard limit for drinking water,with a maximum value and an average of 7. 11 and 1. 51 mg /L,respectively,and fluorine concentrations at 39. 22% wells range from 1. 00 to 2. 00 mg /L,a...
