In the U.S. the Environmental Protection Agency protects drinking water quality through the administration of the Safe Drinking Water Act.  Up to 100 tests a day are performed on the drinking water you receive at your home or business. These tests are repeated daily to make sure your water meets every health and safety standard set by the state and federal government.
Since 1999, water suppliers have been required to provide Consumer Confidence Reports (CCRs) to their customers on an annual basis.  These reports are due by July 1 each year and include information on any contaminants found in the drinking water, possible health effects, and the water’s source.  You can find additional information about City of Mesa drinking water at:
