The land application of biosolids is supported by years of scientific research and practical experience, and is regulated by the U. S. Environmental Protection Agency (EPA) and the Virginia Department of Environmental Quality (DEQ).

DEQ issues permits and regulates independent biosolids land application contractors and regulates Virginia municipalities that have their own land application programs. DEQ operates under the authority of laws passed by the Virginia General Assembly and the U. S. Congress, as administered by the EPA.

These agencies maintain websites that provide an overview of their programs and describe the regulations that they administer.
