A map reveals widespread, alarming arsenic contamination in US drinking water systems. Many areas exceed 5 micrograms per liter (μg/L), with a significant number of Americans potentially affected. Rural and low-income populations are disproportionately at risk, with studies indicating over two million Americans might consume arsenic-contaminated water. The map highlights severe concentrations in places like Michigan's Lower Peninsula, where industrial factors contribute. The research also shows that even low arsenic levels can lead to significant health problems, including cancer and cardiovascular diseases, and calls attention to the need for awareness and action.
The map created by scientists at Columbia University displayed alarming hotspots for arsenic contamination, significantly exceeding the World Health Organization's guideline, with levels posing serious health risks.
Research indicates that even modest arsenic exposure can lead to increased risks of cancer, cardiovascular disease, and developmental issues for affected communities.
Data collected suggested that more than two million Americans may experience arsenic exposure, particularly in rural and low-income areas with chronic contamination.
The highest arsenic concentrations were found in Michigan's Lower Peninsula, potentially linked to industrial and agricultural activities in the region.
