Recommendations for Arsenic Removal from Private Wells

Arsenic is a naturally occurring element found in soils and groundwater. Arsenic concentrations vary in accordance with geographic location. When arsenic levels are found to be too high at a specific location, it may be necessary to treat drinking water to remove it. Arsenic usually exists in two different forms, or valences, in a natural setting
