Reston, VA – A new book by the American Society of Civil Engineers looks at tools used to estimate the maximum amount of pollutant a body of water can receive in a day and still meet applicable water quality standards.

Total maximum daily load is a regulatory term used by the U.S. Clean Water Act, the ASCE said in a news release. The TMDL is an important means of preventing deterioration of the U.S. water supply and reversing the effects of both point- and nonpoint-source pollution on water quality. 

Total Maximum Daily Load Analysis and Modeling: Assessment of the Practice reviews the available tools for estimating the maximum amount of a pollutant that a water body can receive in a day and still meet the applicable water quality standards.

The 170-page publication addresses variety of concerns about the selection and use of analysis and modelling tools for TMDL development and implementation. The source, capability, and applicability of various models and procedures are included.

Additional chapters cover implementation; remote sensing and geographic information systems to gather data; calibration, validation and testing; uncertainty analysis and defining safety margins; as well as a case study.

Environmental engineers, watershed managers, and water quality regulatory officials will use this book to make informed selections of appropriate analysis and modelling tools for TMDL development or implementation studies.
