Historically, arsenic has been used as a medicine, and is still used in some cancer treatments, where the sideeffects may be tolerated. Arsenical medicines were particularly popular in the 19th century until their association with keratosis and skin cancer was recognised. Some were simply quack medicines, but others such as Fowler’s Solution were still in use in the 1970s (Meharg, 2005). Fowler’s Liquor Arsenicalis was a 1% solution of potassium arsenite, taken internally, and was promoted as a cure for ague, fever and headache.

There are three approaches to mitigating arsenic polluted water supplies: treat the contaminated water; resink the well at some distance away or at different depth; or develop a surface-water supply. There is no single best solution. Treating groundwater always involves significant cost and effort in operation and maintenance, and methods must be matched to the water quality, the size of installation, and the skills of the operators. Developing deeper groundwater is popular, but involves risks of contamination over time.

Thus, there are two competing means of trapping arsenic in minerals, under oxidising and reducing conditions, and so arsenic contamination occurs where, for reasons described later, neither sulphides nor oxides can remove arsenic from solution. The causes of natural arsenic pollution of groundwater In natural waters, arsenic is usually found in one of four chemical associations, which occur in more-or-less predictable geological and climatic settings, and each of which is associated with a characteristic cause, or mobilisation mechanism.
