Is dermal exposure to arsenic in drinking water from bathing a concern?

Hand washing and bathing do not pose a known risk to human health (Arsenic Treatment Technology Evaluation Handbook for Small Systems, EPA816-R-03-014, July 2003). The primary mode of exposure to arsenic is ingestion of water containing arsenic. Dermal exposure (i.e., skin contact) with water containing arsenic is believed to be low because dermal absorption of arsenic is minimal. At this time, EPA is basing health risks on estimates of arsenic exposure from food and water (65 FR 38887, 38894; June 22, 2000).
