A recent study published in the journal Nature Geoscience revealed that certain areas in the United States have higher levels of PFAS (perfluoroalkyl substances) in their drinking water. PFAS, also known as 'forever chemicals' due to their slow breakdown rate, are commonly used in industrial processes and consumer products, with two main chemicals being PFOA and PFOS.
Researchers from the University of New South Wales analyzed a global dataset of over 12,000 surface water samples and 33,900 groundwater samples dating back to 2004 to assess the prevalence of PFAS in the environment. The study found that nearly 70% of the samples exceeded Canada's safety standards for PFAS, with 6% surpassing the European Union's limits.
In the U.S., PFAS 'hot spots' were identified in the Midwest, New England, and the West Coast, although detections were reported in other regions as well. Globally, high levels of PFAS were found in Australia, Europe, and China.
Dr. Mark Fischer from International SOS highlighted that most Americans have traces of these chemicals in their blood, primarily from contaminated food and water. The CDC noted that PFAS exposure can lead to various health risks, including cancers, liver issues, lower birth weight, and elevated cholesterol levels.
The Environmental Protection Agency warned of additional dangers such as heart problems, immune system damage, and developmental issues associated with PFAS exposure. Despite PFAS contamination being reported in all 50 states, the levels of these chemicals vary across different regions and cities.
