Two other sources of arsenic, especially of some concern for children, is arsenic in groundwater and subsequently, in rice that is grown in such groundwater. Rice is a common food for children but to date, there are no regulations about the levels of arsenic that are considered safe for consumption.
Arsenic level between 10 ppb and 500 ppb*. Do not drink your water or use it to prepare foods that require a lot of water (e.g., infant formula, soups, Jell-O, rice, coffee, tea) if the arsenic level is above 10 ppb.Washing foods and dishes in the water is safe, and is not a significant source of exposure.alcium supplements made from seashells may also contain high levels of arsenic. Arsenic has been found in private drinking wells throughout Wisconsin. Homes that are near waste sites where paint, pesticides or electronic components are disposed of may also have arsenic in the drinking water.
