What a water report can tell you
A public water-system report can describe source water, monitored substances, reported results and regulatory information for a defined reporting period.
01
Identify the system
Use your water bill or your utility’s official website; ZIP code alone may not identify your supplier.
02
Find the reporting year
Check which time period the measurements cover and whether there are later notices.
03
Read the results in context
Look at the measurement units, the applicable standards, and any reported violations or advisories.
EVERY TAP HAS A STORY
Your household may need its own answers
Private wells and household plumbing are not fully described by public water-system reports. If an official advisory applies to your area, follow the directions from your water provider or public health authority.
