The Water Quality Management Branch (WQMB) is part of the Water Supply and Water Resources Division of the Office of Research and Development's National Risk Management Research Laboratory's (NRMRL). WQMB addresses areas of investigation that align with NRMRL's mission and the overarching strategic plan of the Office of Research and Development. Our interdisciplinary team of scientists, engineers, and technicians provide technical support to EPA's Office of Water, EPA regional offices, state governments, communities, and homeowners. Staff members also engage in collaborative research with water utilities, consultants, and academic institutions.

Our Focus

WQMB resource managers face ever increasing challenges, such as climate change, land use alteration and population growth. WQMB research involves the entire water cycle as it affects water resources. Our researchers conduct experiments on managing water quality in a wide variety of environments including drinking water, ground and surface water, wastewater, and reused/recycled water. Our research involves monitoring and assessing the factors that impact water quality in these settings, and provides results for improving our ability to meet water quality criteria for specific end uses of the water.

Key research areas:

WQMB researchers 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 planning tools that will incorporate new and innovative ideas for sustaining the nation's water resources. To conduct our research we utilize several highly specialized water research facilities located in the Greater Cincinnati, Ohio area: the Andrew W. Breidenbach Environmental Research Center; the Test and Evaluation Facility; and the Experimental Stream Facility.
