Fluoride is one important contaminant released by geogenic process.
Dear Sunil,
Currently, there are several techniques for the partial elimination of fluorides from drinking water but which nevertheless guarantee a supply of fluorides conforming to standards, such as adsorption on a bed of activated alumina, on tricalcium phosphate beds, coagulation-flocculation with Aluminum salts, membrane processes or chemical precipitation with lime. This process becomes particularly valuable if the water contains sufficient magnesium.
With my best regards
Prof. Bachir ACHOUR
I understand that you want to eliminate the fluorite content from the aquifer system itself. How is it possible, when you yourself know the origin of fluoride in groundwater is because of geologic or geogenic reasons. Like Mr. Malek has stated, by injecting water of better quality through artificial recharge or any other method one can try to dilute the fluoride concentration in a given area. Of course, if it is de-fluoridisation after pumping out the groundwater, then as Prof. Bachir has indicated there are many established methods or techniques available.
When I was facing the problem of groundwater rich in fluoride in Eastern Africa I found some Literature about cleaning technologies. I recommend the article "Ground Water Contamination with Fluoride and Potential Fluoride Removal Technologies for East and Southern Africa" from Bernard Thole 2013.Looking at the website of the Ministry of Water of the Republic of Tansania you'll find as well some interesting articles.
Dear Sunil,
The removal of fluoride from an aquifer itself is not possible. But, its concentration can be reduced through dilution by injecting water into the aquifer (artificial recharge). Some have already mentioned this.
Various researchers have applied this method and was found to be effective in insitu dilution of fluoride content.
However, several investigations have been carried out on defluoridation of groundwater (pumping out groundwater) - Prof. Achour has given some indications.
I have provided a brief review on defluoridation of groundwater on reply of a question. You may read the same (link given below).

In this context, I like to mention that we have developed a method for defluoridation of water and filed for patent (The technology already transferred).
Best wishes
As suggested by others, injecting water into the aquifer has a chance of diluting the floride content.
I agree with Asit Kumar Batabyal comment that the removal of fluoride an aquifer is difficult not possible, It can reduce the concentration of fluoride by
njecting water into the aquifer (artificial recharge). Some have already mentioned this.
