Quantitative PCR (qPCR) is a top option for Legionella testing in hospitals, senior living communities, and healthcare facilities because it delivers results in just 24 hours, which is critical when fast action is needed to protect health and safety.

Quantitative PCR detects Legionella DNA in water samples, identifying harmful bacteria faster than traditional culture tests. While culture tests take 7 to 14 days and detect only live bacteria, qPCR offers rapid insight for emergency response, post-remediation checks, and proactive screening. qPCR provides a faster, more responsive solution to minimize risk and ensure water system safety.

Chlorine dioxide is a proven method for secondary disinfection, helping control Legionella in hot water systems across hospitals, universities, hotels, and government buildings.

Chlorine dioxide is generated on-site as a 99.5% pure solution and delivered directly to domestic water lines to eliminate Legionella and other pathogens. It requires no external storage tank, supports multiple dosing points from a single generator, and includes built-in safety interlocks, detailed reporting, and optional remote monitoring. The system uses optical and flow sensors to track performance, helping facilities optimize costs and maintain consistent disinfection.

ORP (Oxidation Reduction Potential) testing is a valuable tool for assessing water’s disinfection potential and plays a key role in Legionella risk management across hospitals, hotels, correctional facilities, and industrial sites.

Measured in millivolts (mV), ORP evaluates the oxidative strength of water by accounting for variables like pH, contaminants, and chemical interactions. Unlike simple free chlorine tests, ORP provides a more complete picture of disinfection efficacy. It helps identify under-treated or over-treated systems. Though not a stand-alone solution, ORP is especially useful in hot water loops and recirculating systems where water chemistry remains relatively stable.
