Water Quality Circulars DEQ has prepared a number of circulars that include the standards and requirements necessary to protect public health and to maintain a high level of water quality in the state. These circulars were developed to comply with the Montana Water Quality Act and other state and federal laws that govern water quality. Some of the circulars are currently being revised and updated.
