Bangladesh Council of Scientific and Industrial Research (BCSIR) are mandated by the Government of Bangladesh to verify /reject performance claims of Arsenic Removal Technologies (ART). This mandate allows no ART to be sold in Bangladesh without verification of its performance claims by BCSIR. ARD/INARS scientist acquired verification/rejection performance claims of Arsenic Removal Technology (ART) through Canadian International Development Agency (CIDA) funded ETV-AM and BETV-SAM project and verify/rejects performance claims of Arsenic Removal Technologies (ART). INARS conducts Inter-laboratory Comparison/round robin of four water quality parameter (Iron, Manganese, Arsenic and Phosphate) test.
