Clean Water Act (at 40CFR 133.104(b)) allows dischargers who have established a
long-term relationship for Biochemical Oxygen Demand (BOD) and Total Organic Carbon (TOC) to substitute U.S. EPA approved methods
for BOD with those for TOC in sampling and analyzing for compliance with their
institutions have attempted to achieve this crossover to TOC because of the
gains in precision, economy, efficiency and accuracy associated with TOC. This
webcast will present three successful models that have been achieved.

Relevance of Topic:
TOC as a substitute for BOD is advantageous in the following respects. It
decreases laboratory costs. This method offers tremendous economic benefits,
particularly for laboratories with small budgets. This method also improves
efficiency—samples can be processed in less time. Quality control is improved.
Where BOD measurements lack precision at low levels of pollutants, such as
trace organic compounds at the parts per billion level, TOC is more precise. Using TOC as a
substitute for BOD improves process control. Operators can make decisions and
adjustments in real time with the data gained from faster TOC measurements.
