A water quality certificate is an official document that confirms a water supply has been tested and meets established safety standards for its intended use—most commonly drinking water.
What Does It Include?
A water quality certificate is issued after laboratory testing and typically outlines:
Contaminant levels – such as bacteria, lead, chlorine, and other substances
Water characteristics – including pH, hardness, and mineral content
Compliance status – whether the water meets regulatory standards
Testing is performed by certified labs and compared against guidelines set by organizations like the Environmental Protection Agency and the World Health Organization.
