The Microbial Contaminants Control Branch (MCCB) is part of the the Water Supply and Water Resources Division of the Office of Research and Development's National Risk Management Research Laboratory's (NRMRL). MCCB addresses areas of investigation that align with NRMRL's mission and the overarching strategic plan of the Office of Research and Development.

Our Focus

MCCB conducts research at the bench, pilot and field-scale focusing on the detection, disinfection, inactivation or otherwise control of microbial contaminants (pathogenic viruses, bacteria, and protozoa) in drinking water, wastewater biosolids and water bodies impaired due to fecal contamination.  MCCB scientists have pioneered the application of both cultural and molecular techniques to the issues of environmental microbiology and public health protection.  MCCB researchers are helping set the national research agenda in the development and use of genetic markers specific for a range of animals and birds that allow for the identification of the sources of fecal contamination in environmental waters.  Using state-of-the-art genomic technologies, MCCB is leading the Agency’s efforts in studying the molecular ecology of microbial communities in such diverse environments as human and animal fecal samples, drinking water distribution system biofilms, groundwaters used for sequestering carbon dioxide and corroded pipe surfaces. MCCB researchers take pride in providing technical assistance to the Office of Water, the EPA Regions and other federal agencies, states, and local governments.

Key research areas:

MCCB researchers aim to provide results for stakeholders, such as utilities and state primacy agencies, in order to better inform decision makers on water management issues.  We strive to develop innovative treatments and tools that will incorporate new and innovative ideas for sustaining the nation's water resources. To conduct our research, we are centered in and utilize EPA's Andrew W. Breidenbach Environmental Research Center, a highly specialized water research facility located in Cincinnati, Ohio.
