LEAGUE CITY — League City residents can raise a glass of tap water with confidence. According to the city’s 2025 Consumer Confidence Report, the public water system met or exceeded all federal and state drinking water standards throughout 2024, with no violations reported.

Water in League City is sourced from both surface and groundwater, drawing from the Trinity and Brazos Rivers as well as the Gulf Coast Aquifer. The surface water is purchased through the Gulf Coast Water Authority and the City of Houston, while groundwater is pumped from various wells throughout the city.

Thorough Testing, Safe Results

The U.S. Environmental Protection Agency (EPA) requires public systems to test for up to 97 contaminants. League City detected several substances during 2024, including lead, fluoride, copper, atrazine, and trihalomethanes — but all were well within safe limits.

Notable findings included:

Additionally, disinfectant levels remained compliant, with chloramine levels averaging 2.47 ppm — well below the maximum of 4 ppm.

Addressing Health Concerns

While the water quality was excellent, the city issued special reminders for at-risk residents, particularly infants, the elderly, and immunocompromised individuals. The report advised these groups to take precautions against microbial contaminants such as Cryptosporidium, which can be harmful despite being rare.

The city also emphasized steps homeowners can take to reduce potential lead exposure, such as flushing taps for 30 seconds to 2 minutes if water has been sitting unused.

Transparency and Tools for the Public

As part of its effort to maintain trust and transparency, the City of League City has developed a public inventory of water service lines, including identification of materials that may contain lead.

Conservation in Action

Beyond safety, League City is also making strides in water conservation. Through its “Captain H2O” initiative, the city promotes practical water-saving solutions such as:

According to the Texas Water Development Board’s 2024 audit, League City reported only 4 gallons per capita per day in water loss — a notably low figure for a growing suburban city.

A Job Well Done

League City’s water utility team, led by Water Production Department Manager Tommy Arredondo, has once again demonstrated effective oversight of this critical resource.

In a time when other U.S. cities have made headlines for the wrong reasons, League City’s continued commitment to clean, safe, and sustainable water stands as a quiet but powerful success story.
