Opportunistic pathogens (OPs) pose a significant health impact but are primarily an issue in premise plumbing systems, which are outside the water utility's jurisdiction. Nonetheless, water utilities may be able to proactively assist their customers and minimize the risks of exposure. This research project seeks to optimize sampling and detection methodologies for OPs (specifically Legionella pneumophila, Pseudomonas aeruginosa, and non-tuberculous mycobacteria [NTM]) and devise suitable monitoring strategies to understand their occurrence in bulk water, biofilms, and sediments in drinking water distribution systems.
