Transport of perchlorate in the Las Vegas Wash and Lake Mead
… fate of perchlorate in the Las Vegas Wash and Lake Mead resulting from the long-term contamination by the manufacturing of rocket fuels in Henderson, Nevada. The changes in perchlorate concentrations for the Las Vegas Wash and Lake Mead were investigated for the last 10 years by analyzing …

Oxidation of trihalomethane-precursors and manganese(II) by chlorine dioxide and permanganate
… the manner that they did. During the period of lake stratification, when trihalomethane removal caused the greatest treatment concerns, chlorine dioxide provided the greatest removal efficiency (65 percent), but organic carbon removal suffered (45 percent), While the lake was mixing and reduced …

Effects of lake trophic state and seasonal cycling on production and bioaccumulation of methylmercury in Te Arawa Lakes
… biota, as well as informing the public about lakes with elevated mercury levels. Previous Hg studies in New Zealand have been limited in scope, with monitoring efforts focused on only a few lakes rather than a comprehensive assessment across multiple ecosystems. Additionally, most existing …

Redox cycling of colloidal macro- and micro-nutrients in a monomictic lake
Lakes are more than just water bodies as they play an essential role in the cycling of nutrients and carbon, with impacts at the local and global scale. This study selected Lake Ngapouri, a small monomictic lake in the Waikiti Valley, Taupo Volcanic Zone, New Zealand, which receives a considerable …

Stable isotopic insight into pelagic carbon cycling in Loch Lomond: a large, temperate latitude lake.
Lakes play an important role in biosphere carbon dynamics. Though proportionally they constitute a small surface feature on the planet, in many cases lakes are subject to significant subsidies of organic material from their catchments. This input of allochthonous organic material, in addition to …

Sensor data analytics and web applications to improve monitoring and understanding of lake processes
Lakes are complex systems that involve numerous physical, chemical and biological processes. With modern sensor technology, large amounts of sensor data on lake water chemistry are being generated to help researchers understand the spatial and temporal patterns of these lake processes. Each sensor …
