High quality in groundwater: essential for perfect drinking water

With professional sampling and accurate laboratory analysis, our water experts at WESSLING guarantee the continuous control of our groundwater. In this way, we make an important contribution to securing the drinking water supply.

WESSLING analyses groundwater and so makes a contribution to high drinking water quality.

Before groundwater deposits are treated to drinking water, WESSLING checks the quality. Our experts use the latest analytical techniques and software to be able to reliably detect pollutants such as pesticide metabolites or pharmaceutical residues.

If groundwater contamination is present, they also prepare well-founded assessments and customised remediation strategies.
