AWWA Webcast: DBP Compliance Approaches

Date: March 09, 2011

Time: 1 – 2:30 pm

Location: i2C Room (2nd Floor, Galbraith Building)


Water utilities are faced with ongoing challenges in the effort to continuously comply with Disinfection By-Products (DBP) regulations. The Stage 2 DBP Rule requires control of disinfection by-products while the Long-Term 2 Enhanced Surface Water Treatment Rule may require elevated disinfection requirements. There are several strategies that can be used to achieve the necessary DBP control: precursor removal, alternative disinfectants, and DBP removal. This webcast explores some compliance approaches for these strategies.

Learning Objectives:

  • Review DBP control strategies
  • Examine the effect of changing source water quality or alternative source waters on compliance at plants using enhanced coagulation and alternative disinfectants.
  • Assess conditions where aeration may be suitable for trihalomethane (THM) control.
