The ability to monitor the arsenic contamination of drinking water wells in Bangladesh is limited due to the very large number of wells (about one million new wells are installed every year) and the high cost of laboratory tests. Jameel et al.  investigated the validity of using field kits as an alternative solution to predict the safe levels of arsenic exposure through comparing dataset pairs of laboratory and field kits tests. Their study found that while the field kits are less accurate, they still provide an acceptable prediction for arsenic contamination and thus can play an important role in the affords of the authorities to reduce arsenic exposure from drinking water in Bangladesh.
