Dear Sri Ravi Sawant,

As per your query, Performance and efficiency of the technique has been evaluated under laboratory conditions by state Govt. and CSIR Laboratories.
For field evaluation, you should contact following organizations.

1) Ministry of Rural Development (Individual States and Central).
2) Department of Science and Technology, New Delhi.
3) Organizations like UNICEF, Water aid.
Many of the above organizations may be having tie ups with NGOs, who can undertake the evaluation, acceptability and sustainability of the techniques developed.

It appears the methods are based on the principle of adsorption. There should be information on the safe disposal of sludge/sorbent loaded with arsenic or fluoride.
