Des Moines Register

Hundreds of Iowans across the state are drinking tap water polluted with poisonous arsenic as health workers move to rein in the problem.
The problem is so widespread that health officials statewide gathered last week in Des Moines to discuss remedies. Large public water supplies routinely test for arsenic. But health officials are now stepping up efforts to encourage private well owners to pay for their own tests, which cost about $20.
The element occurs naturally in Iowa’s soil. It leaches into ground water, which is the source of tap water for 55 percent of Iowans.
Drinking large amounts of arsenic over decades could lead to cancer of the skin, bladder, lungs, liver and prostate, as well as cardiovascular and respiratory problems. Short-term exposure to very high levels can cause nausea, vomiting, diarrhea and skin problems, according to the U.S. Environmental Protection Agency.
