Health Officials Are Studying the Extent of Arsenic Contamination in Ohio’s Wells
The US Geological Survey is working with state health officials to test a broad sampling of water in Ohio in an effort to find arsenic “hot spots” in groundwater.
The EPA lowered the arsenic drinking-water standard from 50 to 10 parts per billion in 2001.
In the public mind, arsenic is often seen only as a poison that kills quickly, but the real danger of arsenic in public water supplies is the long-term effects of relatively small amounts. People who drink water contaminated with arsenic for years are at higher risk of developing skin, liver, bladder and lung cancers.
