### The Key Differences and Similarities

Monitoring bacteria levels in cooling water systems is vital to the operating life, efficiency, and functionality of a well-run system. Unmonitored microbiological activity can lead to deposits, corrosion, blockages, downtime, increased energy usage, and possibly even disease. There are many variables in **field** versus **laboratory** bacteria testing that need to be considered in order to take the proper course of action when required. While differences are expected between these two testing methods, both offer various advantages. Ultimately, trends over time and after specific events offer the most clarity.

Whether testing in a lab or in the field, results from microbiological water analysis must be dependable and accurate to maintain proper system control. A highly trained Chem-Aqua water treatment professional can help to maintain the right system chemistry to ensure that a facility’s systems remain optimal and compliant. Check out this [infographic](https://www.chemaqua.com/Portals/CA/Images/Dip%20Slides%20vs.%20Lab%20MB%20Testing_Large.png) to learn more about the differences between field and lab testing.
