What is Arsenic? Arsenic is a naturally occurring substance that can be found in air, water, and soil. It can also be released into the environment by certain agricultural and industrial processes, such as mining and metal smelting. Arsenic comes in two forms (organic and inorganic); the inorganic form is more toxic than the organic form.

the Site is a location of a former arsenic mine. Historic mining operations occurred in the mid-1800's through 1918. At first miners believed that they had found a silver mine based upon the coloring of the mineral until it was sent out for analytical which determined that the mineral was actually arsenopyrite.

Obtain arsenic as a by-product of mining and refining other metals. Recover the flue dusts produced from copper, nickel and tin, which are high in the arsenides of these metals. Heat them in air to sublimate the arsenic and cool the gas to condense the arsenic back into a solid. This method accounts for most of the arsenic production in the world.

Arsenic also can be released into groundwater as a result of human activities, such as mining, and from its various uses in industry, in animal feed, as a wood preservative, and as a pesticide. In drinking-water supplies, arsenic poses a problem because it is toxic at low levels and is a known carcinogen.

Mining and Arsenic. Arsenic occurs in various mineral forms, as arsenides in sulphide minerals and as arsenates. The most common mineral is arsenopyrite (FeAsS), which is also found in arsenolite (As 2 O 3), olivenite (Cu 2 OHAsO 4), mimetite (Pb 5 Cl(AsO 4) 3 and cobaltite (CoAsS).. In the weathering of sulphides, arsenic can be oxidised to arsenite and arsenate.
