Date & Time:

The Disinfection By-Products Rule training will be held on the following date and time:

August 10 | 10:00AM-12:00PM 

This training is being held in Pacific Time. 


Certain commonly used drinking water disinfectants can react with naturally occurring materials in the water to form disinfection by-products (DBPs), which may pose long-term health risks. The Long-Term 2 Enhanced Surface Water Treatment Rule (LT2ESWTR) and the Stage 2 Disinfection By-Product Rule (DBPR) are the second phase of regulations meant to strengthen protection against microbial contaminants, and at the same time reduce the potential health risks of DBPs. This workshop will examine the factors and causes of DBP formation and the regulatory framework of the Stage 1 and Stage 2 DBPR. 

Participants will learn:

  • The differences between the Stage 1 and Stage 2 rules
  • How to Calculate Locational Running Annual Averages (LRAA) and flow-weighted averaging for compliance reporting
  • How to identify a Combined Distribution System (CDS) and whether it applies to you
  • Alternative disinfectants and application practices that may reduce or eliminate DBP formulation


Regulation Basics Series: The recommended audience includes operators and managers or water systems that chlorinate their water.
