The effectiveness of educational interventions to enhance the adoption of fee-based arsenic testing in Bangladesh : a cluster randomized controlled trial . Arsenic ( As ) testing could help 22 million people , using drinking water sources that exceed the Bangladesh As standard , to identify safe sources . A cluster randomized controlled trial was conducted to evaluate the effectiveness of household education and local media in the increasing demand for fee-based As testing . Randomly selected households ( N = 452 ) were divided into three interventions implemented by community workers : 1 ) fee-based As testing with household education ( HE ) ; 2 ) fee-based As testing with household education and a local media campaign ( HELM ) ; and 3 ) fee-based As testing alone ( Control ) . The fee for the As test was US $ 0.28 , higher than the cost of the test ( US $ 0.16 ) . Of households with untested wells , 93 % in both intervention groups HE and HELM purchased an As test , whereas only 53 % in the control group . In conclusion , fee-based As testing with household education is effective in the increasing demand for As testing in rural Bangladesh .
