Arsenic is one of the naturally occurring elements that are carcinogenic and contributes alot in contaminating our drinking water especially that the state (Kaduna) was blessed with rocks which contain arsenic, agricultural and industrial activities also contribute in bringing arsenic into the environment. Apart from cancer, there are other diseases associated with high concentration of arsenic in the body and still not much work has been done on this element, arsenic in Nigeria. So many researches on arsenic have been conducted in some developing countries like Bangladesh and India with the support of World Health Organisation (WHO). These countries have gone far and even developed an inexpensive way of treating water containing high concentration of arsenic for instance Bangladesh, that was certified by WHO but no similar research is taking place in Nigeria. The authors therefore thought of the need for the level of this contaminant to be known.
