There was no detectable leaching (detection limit µg/L) of antimony into the highpurity water or the well water; however, leaching occurred into tap water, but only after 7 days of contact. After 7, 28 and 90 days'' contact time, the amount of antimony leached into tap water resulted in final concentrations of, and µg/L ...
MIW is defined as any water whose chemical composition has been affected by mining or mineral processing and includes acid rock drainage (ARD), neutral and alkaline waters, mineral processing waters and residual waters. MIW can contain metals, metalloids and other constituents in concentrations above regulatory standards.

Antimony. Antimony is a semimetallic chemical element which can exist in two forms: the metallic form is bright, silvery, hard and brittle; the non metallic form is a grey powder. Antimony is a poor conductor of heat and electricity, it is stable in dry air and is not attacked by dilute acids or alkalis.
