Frequent Questions

Where can I find out about my drinking water or private well?

EPA’s Office of Water (OW) provides information for consumers about drinking water supply, quality, and regulations. Consumers can find out about water quality in their community, how drinking water is regulated, and how they can get involved with drinking water protection. 

EPA identifies and sets limits for the amounts of contaminants in drinking water. Contaminant standards are required by the Safe Drinking Water Act (SDWA).

A Consumer Confidence Report (CCR) is an annual water quality report delivered by community water systems to their customers. The CCR includes information on source water, levels of detected contaminants, compliance with drinking water rules, and other general information. Reports are due to customers by July 1st of each year.
