Article 67: Microbes and Urban Watersheds: Ways to Kill 'Em
ثبت نشده
چکیده
M anaging microbes from urban watersheds can be a daunting task, as bacteria are usually present in high concentrations during storms, come from many different sources, and follow many complex pathways to reach receiving waters. In this article, we examine whether it is technically feasible to reduce microbes in urban stormwater to maintain drinking water, water contact recreation and shellfish consumption uses. The article begins with a discussion of the causes of bacteria mortality, and then reviews what is currently known about bacteria removal provided by stormwater best management practices, stream buffers, and source controls. The major focus is on fecal coliform bacteria, as this indicator has been used in nearly all performance studies conducted to date.

Article 17: Microbes in Urban Watersheds: Concentrations, Sources and Pathways
M icrobes are problematic. They are small and include hundreds of groups, species, biotypes and strains. They are ubiquitous in the environment, found on nearly every surface of the earth. They exist within us, on us, on plants, soils and in surface waters. They grow rapidly, die off, survive or multiply depending on a changing set of environmental conditions. Some microbes are beneficial to hu...

متن کاملSources and transport of nitrogen in arid urban watersheds.
Urban watersheds are often sources of nitrogen (N) to downstream systems, contributing to poor water quality. However, it is unknown which components (e.g., land cover and stormwater infrastructure type) of urban watersheds contribute to N export and which may be sites of retention. In this study we investigated which watershed characteristics control N sourcing, biogeochemical processing of ni...
