Arsenic in Drinking Water
Health Effects
Long-term exposure to arsenic in drinking water increases the risk of skin, bladder, lung, and kidney cancer. It can also cause skin changes, cardiovascular problems, and developmental effects in children.
How Arsenic Gets Into Water
Naturally present in rocks and soil in many regions. Also enters water from mining operations, agricultural pesticides, and industrial waste. Groundwater sources tend to have higher levels.
How to Remove Arsenic
Reverse osmosis removes up to 99% of arsenic. Specialized adsorption media and iron-based filters are also effective. Standard carbon filters do not remove arsenic.
