New Publication Analyzes Available Tools to Measure Pollutants in Water
May 26, 2017

The American Society of Civil Engineers (ASCE), America’s oldest national engineering society, has announced the availability of a new publication, Total Maximum Daily Load Analysis and Modeling: Assessment of the Practice.

Total maximum daily load, or TMDL, is a regulatory term used by the U.S. Clean Water Act. 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. ASCE’s new publication 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.

A variety of concerns about the selection and use of analysis and modeling tools for TMDL development and implementation are addressed. 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.

The new publication will enable environmental engineers, watershed managers, and water quality regulatory officials to make informed selections of appropriate analysis and modeling tools for TMDL development or implementation studies.
