Know your water provider.
Then ask about your tap.
Official water quality reports describe a public water system. Start by finding the provider on your water bill, then read the report that applies to your service address.

A city name or ZIP code alone does not identify your water system. Check your bill first. These links lead to the providers' own reports and tools.
OUC
Orlando Utilities Commission serves Orlando and portions of Orange County. Its official water services page includes the water quality report in English and Spanish.

Look up your ZIP · EWG data
Explore water records for your ZIP.
Enter a Florida ZIP code to see a locally verified EWG record and its historical summary. Coverage is being expanded; a ZIP can contain several water systems. Confirm yours on the bill before relying on a result.
Compare EWG's records by water system.
The Environmental Working Group (EWG) publishes historical utility testing data and compares some results with its health guidelines. For example, its OUC record lists 7 of 16 detected contaminants above EWG guidelines (data through 2023). Orange County Utilities has separate East, South and West records, with 3 of 11, 12 of 29 and 6 of 19 respectively (data through 2024). These counts are not the number of federal legal violations.

Match the system name on your bill or provider map before opening a record. EWG guidelines are comparison benchmarks, not legal limits or a test of your household tap. Check each record's data years and the provider's latest official report. Read EWG's methodology for how its guidelines and counts are selected.

Three checks before drawing conclusions.
01
Identify the provider
Look at your water bill. In an apartment or a community with included utilities, ask the manager which public water system supplies the address.
02
Choose the right report
Providers can operate more than one service area. Match your address or system name to the report before reading its measurements.
03
Separate system data from home data
An annual report summarizes testing across a public system. Plumbing and conditions at your own tap can differ. A targeted home or laboratory test answers a different question.
Using a private well?
Your well needs its own testing.
A utility report does not apply to a private well. The EPA recommends annual testing for total coliform bacteria, nitrates, total dissolved solids and pH, with additional tests based on local conditions and concerns.
