Dissolved organic Nitrogen: an overlooked pathway of Nitrogen loss from agricultural systems?
Received for publication June 18, 2008. Conventional wisdom postulates that leaching losses of N from agriculture systems are dominated by NO3–. Although the export of dissolved organic nitrogen (DON) into the groundwater has been recognized for more than 100 yr, it is often ignored when total N budgets are constructed. Leaching of DON into stream and drinking water reservoirs leads to ...

Drinking water: the problem of chlorinous odours
Chlorinous off-flavours in drinking water are a leading cause of complaints to Australian water utilities and other utilities worldwide. The occurrence and causes of chlorinous odours in drinking water were investigated with the use of an odour panel, trained using a modified flavour profile analysis technique. A new system for classifying water types according to the causes of chlorinous ...

Effect of total organic carbon and aquatic humic substances on the occurrence of lead at the tap
Homes with lead service lines (LSLs) in the City of Brandon, Manitoba, Canada, were found to exceed the provincial standard of 10 μg/L for lead in drinking water. Solids identified by X-ray diffraction of LSL scale were Pb5O8 and PbO2, indicating that lead(II) solids in the LSL scale have been oxidized to lead(IV) solids by free chlorine residuals. Natural organic matter (NOM) can reduce PbO2 ...

Heuristic burst detection method using flow and pressure measurements
Pipe bursts in a drinking water distribution system lead to water losses, interruption of supply, and damage to streets and houses due to the uncontrolled water flow. To minimize the negative consequences of pipe bursts, an early detection is necessary. This paper describes a heuristic burst detection method, which continuously compares measured and expected values of water demands and ...

Water technology magazine features an article on ITS president
Lead contamination — as well as other metals that could be found in plumbing systems — presents serious risks for members in a household, especially children. Recent studies show that lead can affect children’s developing brains when it enters the body in abundance and displaces zinc and ultimately disrupts brain cell growth. For adults, approximately 80 percent of lead that is ...
