Wasteload Allocation Studies
Under the federal Clean Water Act, the Total Maximum Daily Load, or TMDL, program provides a framework for identifying and cleaning up impaired waters. The state is required to develop a TMDL for all waters included on the 303(d) list. Water Quality Monitoring Section staff contribute much of the field work required for TMDL calculation.
After management controls have been implemented on an impaired waterbody, it is often necessary to perform additional studies to reassess water quality or biotic integrity. This allows the Water Pollution Control Program to determine the success or failure of controls that were implemented.
