What to do about it
A certified point-of-use filter is the most direct fix for most of these contaminants. Match the filter to what's actually in your water — a filter certified for lead may do nothing for PFAS or fluoride.

Sources & method. Contaminant levels and violations come from EPA's Safe Drinking Water Information System (health-based violations, 2016–present); PFAS from EPA UCMR5 monitoring (2023–2025). Levels shown are the highest recorded value in the violation records; a violation means the contaminant exceeded its federal limit at the system level. Your home's water can differ from the system average. Public domain data; we are not affiliated with the EPA.
