When you turn on the tap, where does the water come from? If you pay a water bill, you are purchasing water
from a public water system, where your water is monitored, tested and the results reported to the federal, state or tribal drinking water agencies responsible for making sure it meets the National Primary Drinking Water Standards. Your water company must notify you when contaminants are in the water they provide that may cause illness or other problems.
Most people in the United States receive water from a community water system that provides its customers with an annual water quality report, also known as a Consumer Confidence Report. Normally, you will receive it with your water bill once a year in July. The report contains information on contaminants found, possible health effects, and the water’s source. If you do not receive a report, contact your water company for this information.
