Durability of changes in phosphorus compounds in water of an urban lake after application of two reclamation methods
The study was conducted on Długie Lake (area 26.8 ha, maximum depth 17.3 m), located in the town of Olsztyn, in north-eastern Poland (the Masurian Lake District). For 20 years starting in the 1950s, Długie Lake was used as a receiver of raw domestic and storm sewage in quantities oscillating between 350 and 400 m3 day–1. This led to complete degradation of the lake, known ...

Preliminary results of water quality assessment using phytoplankton and physicochemical approaches in the Huai River Basin, China
Water pollution has been a significant issue in the Huai River Basin (HRB) of China since the late 1970s. In July and December 2013, two field investigations were carried out at 10 sites along the main streams of the basin. The monitoring indices contained both physicochemical variables and the structure and composition of phytoplankton communities. The correlations between communities and ...

Using ATP measurements to optimize and validate flushing activities
A Louisiana, USA municipality performed a survey of their potable water distribution system in September 2013. A total of 47 sample taps were tested for Free Chlorinie, Total Chlorine, and Cellular ATP using LuminUltra's Quench-Gone Aqueous (QGA) test kit. Summary of Findings The results of the initial survey showed that more than half of the sample points carried less than 0.5mg/L of Total ...

Diffuse phosphorus models in the united states and europe: their usages, scales, and uncertainties
Received for publication February 3, 2008. Today there are many well-established computer models that are being used at different spatial and temporal scales to describe water, sediment, and P transport from diffuse sources. In this review, we describe how diffuse P models are commonly being used in the United States and Europe, the challenge presented by different temporal and spatial scales, ...

Tackle Harmful Algal Blooms With Near-Surface Circulation - Case study
A Georgia county is winning the battle with blue-green algae (cyanobacteria) on its surface water supply through near-surface circulation. Circulators paid for themselves in three years, cut the need for chemicals, restored water quality and the natural food chain, and eliminated taste-and-odor issues for potable water customers. LAKE VARNER in Newton County, Ga., about 35 miles east of ...

Massive AMD release sparks collaborative approach to watershed restoration - Case Study
AN IMPERILED WATERSHED FINDS A FRIEND In the spring of 1994, an illegally-sealed, major underground coal mine blew out a hillside near Albright, West Virginia, pouring millions of gallons of toxic, acid mine drainage (AMD) into a section of nearby Muddy Creek. The release entered the main stem of the Cheat River turning the river orange for miles. The acidic discharge lowered pH levels in Cheat ...

Conservation is complicated, and all approaches need to be on the table
Dispatches from the front line suggest an important role for a novel ecosystem approach to conservation In a recent essay in this magazine, Daniel Simberloff and co-authors liken the novel ecosystem concept to “a Trojan horse for conservation.” Although I understand their concern, I find their outright condemnation of the idea shortsighted. As one who has published with authors on ...

2010 Filtrexx Sustainability Report
There is a romantic longing to return to nature, to go green. But rare are the opportunities to do so without sacrificing efficiency, economy or other measures of performance. Our relationship to the land is ironic in this sense; we profit from plundering it but are depleted by its depletion, because renewal is not something we can bestow on our inanimate creations. The problems made by man ...

Water Scarcity & the Whisky Industry
Water resources underpin every aspect of modern society and without them everything would eventually grind to a halt… including whisky distilling! In fact, the industry is very water intensive, with water one of the three essentials necessary to facilitate the process, alongside malted barley and yeast. The word ‘whisky’ actually comes from the Gaelic uisge beatha, which means ...

Prediction and evaluation of natural self–restoration of the water of Mahmoudiya canal, western part of Nile Delta, Egypt
The objectives of this paper are to study the effect of discharge of Zarqun drain into Mahmoudiya canal on the natural self–purification along the canal stream and to suggest and simulate different scenarios to improve the water quality of the Mahmoudia canal system to safely discharge water of Zarqun drain into it. Natural self–purification model based on oxygen sag curve introduced by Streeter ...

Water quality index as a tool for wetland restoration
Worldwide, wetlands are subjected to increasing anthropogenic pressures resulting in loss of their hydrological and ecological functions. Such impacts are more pronounced in the case of wetlands in urban areas which are exposed to land use changes and increased economic activities. In many Indian cities, natural water bodies such as lakes are heavily polluted due to runoff from farmlands in ...

Water quality assessment and conservation strategies for the upper stretch of Hindon river – a tributary of Yamuna, India
The study was conducted to know the pollution status of upper stretch of Hindon River and its temporal changes over monsoon, post-monsoon and pre-monsoon seasons due to change of physiochemical parameters during the period June 2011 to May 2012. The upper stretch of the river receives large amount of untreated domestic discharge, agricultural runoff and industrial effluents and now considered to ...

Scale-dependence effects of landscape on seasonal water quality in Xitiaoxi catchment of Taihu Basin, China
Further understanding the mechanisms of landscape–water interactions is of great importance to water quality management in the Xitiaoxi catchment. Pearson's correlation analysis, stepwise multiple regression and redundancy analysis were adopted in this study to investigate the relation between water quality and landscape at the sub-catchment and 200 m riparian zone scales during ...
