The USGS Ohio Water Microbiology Laboratory addresses water-related public-health concerns and is involved in investigations of processes that affect microorganisms in the environment and testing of new methods to improve detection and interpretation of microbiological presence in water.
Amie M Brady
Amie is the supervisor of the Public Health Science and Laboratory Sevices section for the Ohio-Kentucky-Indiana Water Science Center and is the Laboratory Manager for the Ohio Water Microbiology Laboratory and the Kentucky Sediment Laboratory.
Amie received her Bachelor of Science (1999) and Masters of Science (2002) degrees in Environmental Science from the Ohio State University. She started her career at the USGS in 2000 at the Ohio Water Science Center working on a variety of water-quality projects. She became the Laboratory Manager for the Ohio Water Microbiology Laboratory and the Kentucky Sediment Laboratory in 2019. In 2020, Amie became the supervisor of the Public Health Science and Laboratory Sevices section for the Ohio-Kentucky-Indiana Water Science Center.
