Metals and their compounds persist in the environment and can be a serious problem in raw water treatment, especially from ground water sources or surface water with a high proportion of agricultural run-off content. They may accumulate in organisms, particularly those near the top of the food chain, and cause a range of toxic effects. Metallic ions present in raw water arise from the leaching of minerals in the ground, from industrial effluents and chemical processes, and from leachates from land fill sites and contaminated land.
