Catchments and waterways near urban, industrial and agricultural areas are high potential impact zones for contamination. SourceDNA is our solution to help waterway managers and authorities rapidly, safely and cost-effectively identify and track contamination in aquatic environments using eDNA. This method involves extracting eDNA from water samples (using qPCR and metabarcoding) to detect both indicator bacteria and potential source species (such as livestock and human DNA) to identify the possible cause of contamination.
