By Dr. Roshanak Aflaki
Wastewater Manager II

Los Angeles, CA ABSTRACTIn July 2001 the court granted a motion to intervene in an existing lawsuit against the City of Los Angeles (City) regarding sewer overflows. In addition to other requirements, the Case Management Order issued by the court stipulated that the City must investigate and mitigate all odor complaints and issues. The City has developed an extensive multi faceted Odor Control Program to address the City's complex odor problem. In this presentation, the source of odor and different methods of mitigation and their advantages and disadvantages are discussed. The City is currently using Public Outreach, Chemical Feed techniques, Maintenance Program and multiple Activated Carbon Scrubbers. In addition, within the next 2 years, the City will install seven air treatment facilities throughout the collection system. This presentation visits different aspects of the City's Odor Control Program.
