What is Arsenic?

Arsenic contamination in groundwater and surface water occurs naturally and from humans. Naturally occurring arsenic is in soil, groundwater, and sediment. Volcanic eruptions naturally dispose arsenic. Industrial processes such as mining, fertilizer, and coal burning release arsenic to surface water, groundwater, and air. The contamination of arsenic in drinking water has shown damaging effects to humans such as heart damage, kidney damage, cancer, and fetal development. The Environmental Protection Agency (EPA) has set the maximum contamination limit for public water at 10 parts per billion (ppb).
