Clear Lake City Water Authority Water Company

This report aims to educate you about your tap water quality and the measures implemented by your water provider to ensure safe water delivery. All water sources, including bottled water, may contain some level of contaminants. The presence of contaminants doesn't necessarily indicate a health risk. For more information about contaminants and potential health effects, you can contact the EPA's Safe Water Hotline at (800) 426-4791.

Water sources (for both tap and bottled water) include rivers, lakes, streams, ponds, reservoirs, springs, and wells. As water travels across land or underground, it dissolves naturally-occurring minerals, sometimes radioactive materials, and can pick up substances from animal or human activity.

Potential contaminants in source water include:

• Microbial contaminants (viruses, bacteria) from sewage treatment plants, septic systems, agricultural operations, and wildlife
• Inorganic contaminants (salts, metals) either naturally-occurring or from urban runoff, wastewater discharges, oil/gas production, mining, or farming
• Pesticides and herbicides from agriculture, urban runoff, and residential uses
• Organic chemical contaminants from industrial processes, petroleum production, gas stations, and septic systems
• Radioactive contaminants, either naturally-occurring or resulting from resource extraction activities

CLCWA WATER SOURCE INFORMATION
Clear Lake City Water Authority obtains approximately 97% of its water from Houston's Southeast Surface Water Treatment Plant near Ellington, with the remaining 3% from groundwater wells. The primary source is surface water from the Trinity River via Lake Livingston, occasionally supplemented by water from the San Jacinto River via Lake Houston. During peak summer demand, the Authority uses deep wells from the Gulf Coast Aquifer.

To ensure tap water safety, the EPA establishes regulations limiting contaminant levels in public water systems, while the FDA sets similar standards for bottled water. Some customers may notice taste, odor, or color issues that don't necessarily pose health concerns. For information about these aesthetic issues, contact our office at 281-488-1164.

Certain populations may be more vulnerable to contaminants, including infants, elderly individuals, immunocompromised persons (such as those undergoing chemotherapy, organ transplant recipients, or people with HIV/AIDS). These individuals should seek medical advice about their water consumption.

Lead in tap water primarily comes from service lines and household plumbing materials. While Clear Lake City Water Authority provides high-quality water, we cannot control the materials used in plumbing components. To minimize lead exposure, flush your tap for 30 seconds to 2 minutes before using water for drinking or cooking. For more information about lead testing, visit http://www.epa.gov/safewater/lead.

1. Where does Clear Lake City Water Authority water come from?
   Clear Lake City Water Authority supplies purchased surface water to Harris County, Texas.
2. Does Clear Lake City Water Authority test its tap water?
   Yes. Like every public water system, Clear Lake City Water Authority must test its water under the federal Safe Drinking Water Act and publish an annual water quality report (Consumer Confidence Report). Ask the utility for the latest report or look for it on its website.
3. How do I contact Clear Lake City Water Authority?
   Call 281-488-1164 or visit 900 Bay Area Blvd, Houston, TX 77058, or use the contact options on the utility’s website.
4. Does Clear Lake City Water Authority water contain lead?
   Water usually leaves the treatment plant without lead. Lead can enter tap water from older service lines, solder and brass fixtures inside homes, especially when water sits in the pipes. Run the tap before drinking if water has been sitting, and ask the utility about lead testing and service line records.
5. Is Clear Lake City Water Authority water hard?
   Hardness depends on the source and changes over time. The annual water quality report lists hardness, or you can test it at home. If it is above about 7 grains per gallon, a water softener sized to your measured hardness will stop scale and spotting.
