Legionella Testing Services

Huntington Beach, California, June 30, 2026

As temperatures rise across California in June, public health experts are urging building owners, facility managers, and institutions to address a serious but often overlooked threat: Legionella bacteria. LA Testing, California’s premier Legionella laboratory and provider of sampling supplies and easy-to-use test kits, is highlighting the increased risks tied to warmer weather and low water usage. 

Legionella, which causes Legionnaires’ disease and Pontiac fever, thrives in warm, stagnant water. Cooling towers, fountains, hot water systems, and plumbing can become breeding grounds under these conditions. As summer heat intensifies, water systems naturally warm, accelerating bacterial growth.

June is a critical time for prevention. Many schools, colleges, and universities reduce occupancy or temporarily close, leading to low water use and stagnation in pipes, key factors in Legionella amplification. When buildings reopen, contaminated water can pose significant health risks.

“Warmer temperatures combined with stagnant water create a perfect storm for Legionella growth,” said Michael Chapman, Laboratory Manager at LA Testing. “Routine testing and proper maintenance are essential, especially in facilities with inconsistent water flow.”

LA Testing provides comprehensive Legionella analysis along with convenient sampling kits for facility personnel. These kits streamline sample collection from cooling towers, potable water systems, and other potential sources. Fast, reliable results enable organizations to take timely corrective action.

In addition to testing, experts recommend flushing unused lines, maintaining disinfectant levels, and routinely cleaning and inspecting water systems. Implementing a water management plan aligned with industry standards can significantly reduce risk.

As California enters its warmest months, LA Testing encourages organizations to remain vigilant. Proactive testing and maintenance protect occupants and support regulatory compliance.
