Where does our municipal water come from? Our water is sourced from surface water supplies including Lake Tawakoni, Lake Ray Hubbard, Lake Fork and/or the Elm Fork of the Trinity River. The Elm Fork receives water from Lake Ray Roberts, Lake Lewisville, and Lake Grapevine.

Special Notice for Vulnerable Populations: Elderly individuals, infants, cancer patients, people with HIV/AIDS or other immune disorders may be particularly susceptible to waterborne infections. These individuals should consult healthcare providers about their water consumption. EPA/CDC guidelines for reducing infection risk from Cryptosporidium and other microbial contaminants are available through the Safe Drinking Water Hotline (800-426-4791).

All municipal water contains some level of contaminants. Even bottled water typically contains small amounts of certain substances. The presence of contaminants doesn't necessarily indicate a health risk. For detailed information about contaminants and potential health effects, contact the EPA's Safe Drinking Water Hotline at (800) 426-4791.

Potential source water contaminants include:

• Microbial contaminants (viruses, bacteria) from sewage treatment facilities, septic systems, or agricultural operations
• Inorganic contaminants (salts, metals) from natural sources, urban runoff, industrial discharges, or agricultural activities
• Pesticides and herbicides from various sources including agriculture and urban runoff
• Organic chemicals from industrial processes, petroleum production, gas stations, and septic systems
• Radioactive substances that occur naturally or result from oil/gas production and mining

The EPA establishes guidelines limiting contaminant levels in public water systems to ensure safety. FDA regulations set similar limits for bottled water. Taste, color, or odor variations in tap water don't necessarily indicate health concerns. For questions about water appearance or smell, contact the Public Works office at 972-462-5150.

Secondary Components: Many elements commonly found in water (calcium, sodium, iron) can affect taste, color, and odor without posing health risks. These secondary components are regulated by Texas rather than the EPA and aren't required in water quality reports.

Water Loss: In the audit submitted to the Texas Water Department Board for January 1-December 31, 2017, Coppell's system lost approximately 18.00% of system input volume. Questions about water loss can be directed to 972-462-5150.

Lead Information: Elevated lead levels pose serious health risks, especially for pregnant women and young children. Lead typically comes from service lines and home plumbing materials. You can reduce potential exposure by flushing your tap for 30 seconds to 2 minutes before using water for consumption. For concerns about lead, consider testing your water. Information about lead in water, testing methods, and exposure reduction is available from the Safe Drinking Water Hotline (1-800-426-4791) or epa.gov/safewater/lead.
