Fourth IWA Specialty Conference on "Natural Organic Matter: From Source to Tap and Beyond"
Held: July 27-29, 2011
Location: Costa Mesa, California USA
Organized By: International Water Association; Urban Water Research Center at the University of California, Irvine; National Water Research Institute; Southeast Environmental Research Center at the Florida International University; Cranfield Water Science Institute at Cranfield University; and University of California Office of the President
Sponsors: Ahlstrom Filtration; Carollo Engineers; Consulate General of Canada; Hazen and Sawyer; Horiba Scientific; National Science Foundation; NeoTech Aqua Solutions; Orange County Water District; Trojan Technologies; United States Environmental Protection Agency; University of California Center for Hydrologic Modeling; Ushio America Inc;, and Water Research Foundation
Purpose: To bring together a diverse group of scientists and engineers who are interested in better understanding the dynamics and impacts of NOM as it pertains to drinking water, wastewater, recycled waters, and natural waters. Because of the increased importance of water reuse, discussions will extend to effluent organic matter (EfOM) as well.
Sessions: Treatment and Removal; Molecular Characterization; Disinfection Byproducts; Monitoring; Advanced Oxidation; Membranes; Photochemistry; and many more.

First International Conference on Microbial Transport and Survival in Porous Media
Held: May 10-13, 2009
Location: Niagara-on-the-Lake, Ontario, Canada
Sponsors: NWRI, Canadian Water Network, Brace Centre for Water Resources Management
Purpose: To advance our understanding of the transport and survival of microorganisms and, particularly, pathogens in subsurface environments and the associated risk of pathogen contamination in groundwater.
Sessions: Transport of colloids and microorganisms in granular, unsaturated, and fractured media; groundwater under the direct influence; microscale investigations of colloid and microbe transport; and a regulatory roundtable discussion, among others.
Plenary Speakers: Charles O'Melia (Johns Hopkins University); Menachem Elimelech (Yale University), Ronald Harvey (U.S. Geological Survey), Charles Gerba (University of Arizona), and Joan Rose (Michigan State University)

Short Course on UV for Wastewater and Water Reuse
Held: March 2008
Location: Orlando, Florida
Partners: International Ultraviolet Association, WateReuse Florida, Carollo Engineers, Black & Veatch
Purpose: To provide the tools and resources needed to help utilities implement cost- and performance-effective UV systems as a reliable treatment technology for waterborne pathogens in wastewater and recycled water.
Brief Summary:
Over 90 participants came together at the UV workshop to learn more about implementing cost- and performance-effective ultraviolet (UV) disinfection systems.
A simple, low-cost, and highly efficient technology, UV disinfection uses high levels of radiation to disinfect water and wastewater, damaging the genetic structure of waterborne pathogens, such as bacteria, viruses, and protozoa, and rendering them non-infectious.
Topics included the following:
- The public health relevance of disinfection.
- Certification processes and certified UV reactors.
- Capital costs and operation costs.
