With nearly three-quarters of Americans using water systems that add fluoride, many have become interested in understanding what’s in their drinking water. Recently, the National Toxicology Program (NTP) released a report finding an association between higher levels of fluoride exposure and lower IQ in children. However, the report clarified that the fluoride levels associated with these findings were more than double those typically found in U.S. drinking water, and it did not conclude that the fluoride levels added to public water supplies are unsafe.
The NTP report highlights the importance of ongoing research, and for some, it renews concerns about potential contaminants. Many Americans—particularly veterans—are often cautious about government studies related to health, questioning what is in the air, water, food, and medicine provided. Yet the report serves as an example of government agencies conducting studies, interpreting results, and engaging in new conversations relevant to public health.
For those interested in understanding what’s in their local drinking water, a resource called the Consumer Confidence Report (CCR) is available. Required annually by the Safe Drinking Water Act, the CCR provides detailed information on drinking water quality, including fluoride levels and other potential hazards like lead, which is widely recognized as harmful. The CCR offers a comprehensive look at local water quality and can guide consumers who are considering additional filtration options.
Checking the CCR for one’s area can help residents gain a clearer picture of their water quality, assess contaminant levels, and determine if a home filtration system might be beneficial. While consumers are encouraged to conduct independent research, the CCR is a reliable starting point for learning about the safety of local drinking water
