The Stuttgart location is one of the GBA Group’s laboratories specializing in water and serves as the headquarters of the Water Business Line. From here, we serve clients nationwide in the housing sector, healthcare, industry, the swimming pool and leisure sectors, as well as public and commercial facilities.

This enables us to conduct sampling and testing efficiently, regionally, and consistently in accordance with uniformly high quality standards.

In addition, we support our clients in complying with legal requirements, evaluating test results, and developing practical measures to ensure consistently high water quality.

In addition to our analytical expertise, we have extensive experience in the housing sector, swimming pools and water parks, as well as evaporative cooling systems, wet scrubbers, and cooling towers. As a result, we understand not only our clients’ laboratory analysis requirements but also the operational, technical, and regulatory challenges of their respective industries.
