  • Comparison of evaporation rate on open water bodies: energy balance estimate versus measured pan

    Much attention has been paid to establish accurately open water evaporation since the lake itself is the largest consumer of water. The aim of this study is to assess the discrepancy in the measured (pan evaporation) and estimated (Penman) evaporation rate, seasonally, based on the results from a 37-year energy budget analysis of Lake Burrumbeet, Australia. The detailed analysis of ...

  • Aeration and mixing bring Hussain Sagar Lake`s ecosystem back to life - Case Study

    Overview Hussain Sagar Lake in India faced an inflow of untreated waste and pollution causing decreasing DO levels and foul odors in the nearby community. An even more critical threat was eutrophication, or an excessive number of nutrients in the body of water, choking out the natural aquatic life. Given the lake is stagnate, circulation and the distribution of efficient aeration ...

  • Safety vs. Environment Protection: Study Discovers Increasing Salt Levels in Lakes

    A recent study published by the US-American National Academy of Sciences revealed an increasing salt amount in form of chloride in rural and urban freshwater lakes around the American continent. The scientists believe, that mainly road salt distributed on icy roadways is to blame. Increasing salt levels threaten eco systems Road de-icing salt is blamed for rising salt levels in ...

  • The impact of changed river discharge on water quality deterioration in a prairie lake revealed by the sedimentary evidence

    In order to investigate the historical water quality state and identify the factors causing modern environmental degradation in a prairie lake, total organic carbon (TOC), total nitrogen (TN), stable carbon isotopes of organic matter and total phosphorus (TP) from lake sedimentary core with high resolution age frame were analyzed. The results show that the values of proxies (TOC, TN, TP, δ13C, ...

  • Great Lakes restoration is under threat. Here’s why that matters

    Degraded by decades of pollution, the North American Great Lakes are finding new life through cleanup efforts now threatened by proposed federal budget cuts. The St. Louis River, which flows into Lake Superior — the greatest of North America’s Great Lakes — has a long and turbulent history. Once a portal for Native American trade and a garden for wild ...

  • The drainage of lake ‘L'Estany’ in Spain

    In the 18th century, the practice of drying up the wetlands, marshy or stagnant water areas expanded throughout Europe in order to avoid the malaria fevers that the population periodically suffered and to recover land for farming. This communication describes the current knowledge about the history of the process of drying in various hydrological basins as well as the works in the endorheic ...

  • Water is a key concern on Earth Day 2017

    Although the official focus of this year’s Earth Day is environmental and climate literacy, water is still very much a key concern for participants holding events across the United States — and around the world. A need for clean water for future generations was the impetus for the original event, and the need to protect water is no less important today. Earth Day was established in ...

  • The best way to restore environments in the face of climate change

    Florida’s Kissimmee River once flowed freely. Fish, birds and other wildlife dwelled in the wetlands it fed. But in the 1960s, spurred by public outrage over flooding, the U.S. Army Corps of Engineers straightened the winding waterway and turned it into a drainage canal. Flip forward a few decades and the river is returning — at least in part. The U.S. Army Corps of Engineers has ...

  • This polluted lake shows why we are all stakeholders when it comes to clean water

    When environmental protection gets short shrift, the price we pay can be staggering. When I visited Onondaga Lake in 1999 as part of research I did as a student at Cornell, there was no evidence the lake was once home to vibrant waterfront resorts. Yet, in the late 1800s and early 1900s, Onondaga was considered “ ...

  • Dynamic simulation of sediment resuspension and its effect on water quality in Lake Taihu, China

    Quantitative studies on sediment release fluxes and their impact on water quality are important for water pollution control, ecological restoration, water safety, and human health. In this study, we conducted high-frequency, synchronous field observations of meteorology, hydrology, and water quality to determine the relationship between sediment release rate and wind speed in the central ...

  • Researchers inventory plastics pollution in Great Lakes

    A recent inventory of plastics pollution in the Great Lakes will help prevent continued pollution and provide a baseline for those working to clean the lakes, which supply local residents with drinking water. The Great Lakes Basin is a system of five bodies of water and their tributaries along the northernmost tier of the United States, four of which border Canada. They include Lake Superior, ...

  • Diffusion flux of phosphorus nutrients at the sediment–water interface of the Ulansuhai Lake in northern China

    Overlying water and sediment samples were collected from 11 locations in Ulansuhai Lake in June of 2012 to determine the concentration of dissolved inorganic phosphorus (DIP) in the interstitial water, overlying water and sediment and to estimate the diffusion flux of DIP at the sediment–water interface. The DIP levels in overlying water were 0.004–0.185 mg/L (average = 0.062 mg/L), while they ...

  • CAIROX Potassium Permanganate - Case Study

    BACKGROUND The Carbondale Water Treatment Plant (Carbondale, Illinois) with a design capacity of 8 MGD and an average flow of 4.6 MGD draws its water from Cedar Creek Lake. Because of moderately high raw water TOC levels (4.3 - 6.5 mg/L) and low alkalinity (36 - 40 mg/L as CaCO3), Carbondale is required to attain 45 percent TOC removal under the Disinfection/Disinfection By-Product ...
