Combating fluoride contamination in Guwahati, Assam: Need recommended action

A part of Guwahati City is already affected with contamination of Drinking water sources with Fluoride. Very recently, the problem has been figured out in some fresh areas with Fluoride contamination of water above permissible limit ( in different ranges upto 3.86 ppm ).

We have advised people from those areas, to avoid such water sources and also to ensure some tips on the food habits as follow.

(a)    Use of safe water source. If needed, an RO may perhaps be used for this purpose. But such RO should be of adjustable nature, so that the TDS level in the water from this RO does not come down to zero, but remains in the level of at least 50 ppm.    
(b)    Regular intake of Milk, Curd, Ladies Finger ( Vindi ).
(c) Habit of consuming foods rich in Vitamin – C like Amla, Lemon etc.
(c)    Avoiding strictly the foods with black salt like, Chips, Fried Channa, Dalmut, Choclate etc.

However, we like to know whether there should be any addition or alteration or any new approach to be adopted into our advise as mentioned above?
