Specify Sustainable Products for Water Treatment
March 11, 2015, 11:00 a.m. - 12:30 p.m. MTN
In this webinar, the viewer will be given information on specifying sustainable water contact products and water treatment chemicals. Details of the NSF/ANSI standards will be provided so the user understands what sustainable products and chemicals are. Utility or municipality managers will learn how to recognize sustainable products and chemicals to specify for use in their operations and how to promote this activity to their communities.
Naegleria fowleri: A New Drinking Water Pathogen?
March 25, 2015, 11:00 a.m. - 12:30 p.m. MTN
This webinar will describe the pathogen Naegleria fowleri and present the concern the pathogen poses in the wake of deaths associated with treated drinking water exposure in Arizona and Louisiana. The organism is an amoeba found in warm waters worldwide but isolated from treated drinking water. It causes a brain infection, primary amoebic meningoencephalitis, or PAM, which is almost always fatal. The route of infection is through the nose when water is forced into the nasal passages, allowing the parasite to travel to the brain and cause infection. It does not pose a threat from ingested drinking water. Occurrence alone in drinking water does not mean there is a risk to public health; but this is a poorly understood pathogen that is relatively new to the US drinking water community. Attendees will learn the basics about N. fowleri, including how samples are collected and analyzed, what the risk factors are for contamination of a water system, and how the state of Louisiana responded by issuing stricter rules on distribution system disinfection and monitoring.
Hydrant Flow Testing: Purpose, Process, and Experiences
April 1, 2015, 11:00 a.m. - 12:30 p.m. MTN
Hydrant Flow Testing will cover aspects of proper measurement related to fire-flow rates and pressures from hydrants in water distribution systems. During the webinar, multiple purposes of testing will be discussed, such as determining available fire-flow rate, system pressures, hydraulic model calibration, operational conditions, including fire-fighting and system flushing; also, testing procedures, data to capture during testing, and calculations to determine available fire-flow rates. Experiences of special situations will be included, such as very high pressures and testing on large-diameter water mains. The webinar will conclude with insight on how test results can prove to be valuable support for utility planning and operations.
