Understanding this report
Health guidelines vs. legal limits: The EPA sets legal limits (MCLs) for contaminants — but these are based on feasibility and cost, not just health. Independent health organizations set stricter guidelines based on the latest science. A contaminant can be “legal” but still exceed health-based guidelines.
“Times above guideline”: This shows how many times higher the detected level is compared to the health guideline. For example, “281x” means the detected level is 281 times higher than what health researchers recommend.
What you can do: A whole-home or point-of-use water filtration system can significantly reduce or eliminate most contaminants. The right system depends on your specific water — a professional water test at your tap is the best way to determine what you need.
