Arsenic can be found in naturally occurring bedrock and contaminate ground water or can infiltrate groundwater from weathering minerals and ores in addition to anthropocentric sources.

Explanation:

Arsenic can be found naturally in high concentrations in localized areas when drilling wells for drinking water can intersect bedrock with arsenic. Additionally, elevated levels of arsenic in groundwater can be near areas of weathering of arsenic containing minerals and ores. Arsenic can also pollute groundwater from various industrial activities such as abandoned mines that runoff or infiltrate groundwater aquifers.

Arsenic can travel in many other ways as described in the picture below:
