Drinking Water Contaminants – Standards and Regulations
This EPA website provides links relevant to regulated drinking water contaminants, developing and reviewing contaminant regulations, and evaluating and monitoring contaminants.

“Epidemiology and Ecology of Opportunistic Premise Plumbing Pathogens: Legionella pneumophila, Mycobacterium avium, and Pseudomonas aeruginosa
A Water Research Foundation–sponsored workshop gathered experts from across the United States to review the characteristics of opportunistic premise plumbing pathogens (OPPPs), identify problems, and develop a list of research priorities to address critical knowledge gaps with respect to increasing OPPP-associated disease. The objectives of this article from Environmental Health Perspectives are to alert professionals of the impact of OPPPs, the fact that 30% of the population may be exposed to OPPPs, and the need to develop means to reduce OPPP exposure. The authors present a review of the epidemiology and ecology of these three bacterial OPPPs, specifically to identify common and unique features. A PDF is also available from this page.

​​Human Health Drinking Water Advisory/Effects Documents for Microbial Contaminants
This EPA reference of relevant documents is housed under their “Drinking Water Contaminant Human Health Effects Information” page. It provides information on Cyanotoxins, Cryptosporidium, Legionella, Giardia, and Mycobacteria.

National Exposure Research Laboratory (NERL)
This page discusses what the NERL does and how it is organized. It also includes links to other​ related EPA resources.

Microbiological Methods and Online Publications
EPA scientists have developed a variety of methods to detect, characterize, and study bacteria, protozoans, viruses, and coliphage. This source provides links to many of these methods.

Standard Methods: Microbiological Examination
This robust resource of standard methods is provided by the American Public Health Association, the American Water Works Association, and the Water Environment Federation.
