Internal Cycling in an Urban Drinking Water Reservoir
… (P) and metal cycling in the Eagle Creek Reservoir (ECR), located in Indianapolis, central Indiana. Eagle Creek Reservoir serves the drinking water needs of over 80,000 residents. Within the last several years, algal blooms have created stress to the local treatment facility. The objective …

Metal fluxes across the sediment water interface in a drinking water reservoir
… of iron (Fe) and manganese (Mn) in drinking water degrade water quality by affecting taste, odor, and color. Under oxic conditions (dissolved oxygen (DO) >2 mg/L), Fe and Mn are rarely present in soluble form in natural waters, as they occur as insoluble, oxidized minerals in …

Insect-Induced Forest Disturbance Impacts on Select Water Quality Parameters in a Closed Drinking Water Reservoir
… timing of precipitation and river inflows impact drinking water reservoirs. Natural organic matter (NOM) directly impacts water treatment process effectiveness and is identified as an emerging contaminant of concern. Few studies have examined how insect-induced forest disturbance contributes to …

The effects of hypolimnetic oxygenation on the chemical, physical, and biological properties of a shallow drinking water reservoir
… phosphorus (P) loads from the sediments to the water column, thereby increasing nutrient availability, making preventing anoxia a major goal for lake managers to improve water quality. Side-stream saturation (SSS), a type of hypolimnetic oxygenation system, has been developed to maintain …

High-frequency sensor data capture short-term variability in Fe and Mn cycling due to hypolimnetic oxygenation and seasonal dynamics in a drinking water reservoir
… of iron (Fe) and manganese (Mn) in lakes and reservoirs have predictable seasonal trends, largely governed by stratification dynamics and redox conditions in the hypolimnion. However, short-term (i.e., sub-weekly) trends in Fe and Mn cycling are less well-understood, as most monitoring efforts …

Cyanobacteria Abundance and Toxin Production in a Drinking Water Supply Reservoir
… organisms that live in marine and freshwater environments and are most common during the warmer months. Many cyanobacteria are also known to release toxins that target cellular processes and affect a wide range of organisms, including people. Although the effects of toxins on …

Hypolimnetic Oxygenation Mitigates the Effects of Nutrient Loading on Water Quality in a Eutrophic Reservoir
… predicted to have many diverse effects on freshwater lakes and reservoirs by increasing both hypolimnetic hypoxia and runoff, which will increase nutrient concentrations and degrade water quality. Hypoxic conditions can trigger the release of metals and nutrients from the sediments, i.e., …

Microbial risk assessment for recreational use of the Kranji Reservoir, Singapore
… is responsible for management of the Kranji drinking water reservoir and wishes to open the reservoir for recreational water use as part of their "Active, Beautiful, and Clean Waters Programme". A field campaign was conducted at the Kranji Reservoir to determine the microbial water and …

Structural dynamics of community gene expression In a freshwater cyanobacterial bloom over a day-night cycle
… the metatranscriptome of a tropical eutrophic drinking water reservoir dominated by the toxigenic cyanobacterium Microcystis aeruginosa over a day-night cycle. Cyanobacterial blooms are a major problem in eutrophic lakes and reservoirs, negatively impacting the ecology of the water body through …

The sources and cycles of iron and manganese in surface water supplies
Evaluation of the sources and cycles of water quality contaminants in watersheds is critical for effective surface water resource management. In particular, iron (Fe) and manganese (Mn), commonly found in rocks and sediments, have adverse impacts on water quality. However, controlling Fe and Mn in …

Untersuchungen zu Eintrag, Verteilung und Verbleib natürlicher organischer Wasserinhaltstoffe aus moorgeprägten Einzugsgebieten von Trinkwasserspeichern
In den letzten 15 Jahren wurde in einigen Mittelgebirgsregionen Zentraleuropas ein regional un-terschiedlich starker Anstieg der Konzentration gelösten organischen Kohlenstoffes (DOC) in Oberflächengewässern festgestellt. Besonders betroffen von dieser Entwicklung sind für die …
