The relationship of arsenicosis occurrences with the arsenic concentrations of drinking water, the economic status of households, and the social classes as caste-jati of households were examined in an arsenic contaminated village in the Terai Region in Nepal. The analysis suggests that while arsenicosis among village residents was undoubtedly associated with the amount of arsenic in their drinking water, their socio-economic conditions seemed to affect the occurrences of arsenicosis cases. In general, poorer households suffer more. At the bottom of the social rank, households belonging to the "untouchable" class are most severely affected by arsenic contamination. The primary reason for the untouchable classes suffering for arsenicosis most seems to be their poor household economics. Moreover, other elements of "human poverty" as defined by UNDP, such as the lack of knowledge, of participation, and of liberty, seem to affect the health status of the untouchable Dalits. One of such factors, the levels of eduation, is examined. The levels of education is correlated with the occurrences of arsenicosis, and that of Dalits turns out to be the lowest of all caste classes.
