Investigations into the sources and removal of taste and odor compounds at two treatment facilities on Eastern Lake Erie and Niagara River
- Erie County Water Authority, Lackawanna, NY (United States)
- Acres International Corp., Amherst, NY (United States); and others
Taste and odor problems in drinking water supplies have been a topic of research since the early 1900`s. Studies have identified various taste and odor compounds, including methyl-iso-borneol (MIB), geosmin, trichloranisole, and their potential sources, to include the phytoplankton genera Aphanizomenon, Anabaena, Microcystis, and Dinobryon. Many methods of treatment have been investigated to mitigate taste and odors, including the addition of copper sulfate and various chemical oxidants, as well as the introduction of bacteria capable of metabolizing oil-like organic compounds. Taste and odor problems associated with drinking water supplies have become increasingly important, in part because public awareness of water quality issues such as chlorine and associated disinfection byproducts, and the perception that malodorous water may be associated with pathogens such as the infectious Cryptosporidium parvum. Due to marked increases in customer complaints beginning in 1993, and elevated levels of the taste and odor compounds. MIB and geosmin, in eastern Lake Erie and the Niagara River, the Erie County Water Authority (ECWA) initiated an investigation into the impact of MIB and geosmin on water quality, assessment of various means of effective removal, and potential sources.
