The details
- The annual water quality report provides insight into what’s in residents’ drinking water. It also provides a list and levels of federally regulated or monitored contaminants found in drinking water.
- Both Lewisville’s and Coppell’s water systems received a “superior” rating, which is the highest rating given by Texas Commission on Environmental Quality, according to the reports.
- Data for Coppell’s report was collected by both the city and the city of Dallas. Coppell’s water comes from surface water sources, such as Lake Ray Roberts and Lewisville Lake, and is purchased from Dallas Water Utilities, according to its report.
- Lewisville treats water at its water treatment plant and purchases treated water from Dallas Water Utility and the Upper Trinity Regional Water District, according to the city’s report. Lewisville’s water treatment plant pumps in water from Lewisville Lake.
- To ensure tap water is safe to drink, the Environmental Protection Agency prescribes regulations which limit the amount of certain contaminants in water provided by public water systems. Food and Drug Administration regulations establish limits for contaminants in bottled water, which must provide the same protection for public health.
