DNA Analyzes for Drinking Water

With the support of the VTU Fund, we have developed a number of DNA analyzes for drinking water over the past couple of years. Unlike source tracing in bathing waters, where we look for differences in the DNA of the bacteria, we lead the new DNA analyzes of the following DNA into the drinking water. This has the unmatched advantage that the source trace is not dependent on the faecal bacteria that rarely cause drinking water contaminants in Denmark or occur in very low concentrations. By analyzing the follow-up DNA that accompanies coliform bacteria into the drinking water in case of contamination, DNA is directly analyzed from the source, which can provide valuable information about the origin of the contamination.
