The City of Coppell recently published its 2021 Water Quality Report providing residents insight into what’s in their drinking water.
This annual report provides a list and levels of federally regulated or monitored contaminants found in the City’s drinking water. Data for the report was collected by both the City of Coppell and the City of Dallas. Coppell’s water comes from surface water sources such as Lake Ray Roberts and Lake Lewisville and is purchased from Dallas Water Utilities.
The City of Coppell consistently exceeds all state and federal drinking water requirements and maintains the Texas Commission on Environmental Quality’s highest rating for public water supplies. View the 2021 Water Quality Report (PDF).
