Heavy metals, PAHs and toxicity in stormwater wet detention ponds
Concentrations of 6 different heavy metals and total polycyclic aromatic hydrocarbons (PAHs) were determined in stormwater runoff and in the pond water of two Danish wet detention ponds. The pond water samples were analyzed for toxic effects, using the algae Selenastrum capricornutum as a test organism. Stormwater and pond water from a catchment with light industry showed high levels of heavy ...

Prospects of pond ecosystems as resource base towards community based adaptation (CBA) to climate change in coastal region of Bangladesh
Climate-induced hazards are adversely affecting the pond ecosystems in Bangladesh. Most of the poor communities collect water from isolated ponds for drinking and other domestic needs. This paper explores how the small pond ecosystems and associated livelihoods of the coastal communities are vulnerable and argues that the pond ecosystem can be a potential resource base for community based ...

Comparison of the ability of two grasses viz., Phragmites karka (Retz.) Trin. ex. Steud and Vetiveria zizanioides (L.) Nash to improve surface water quality in a constructed wetland
The aim of the study was to investigate the ability of two grasses viz., Phragmites karka (Retz.) Trin. ex. Steud (Common reed) and Vetiveria zizanioides (L.) Nash (vetiver), to improve the quality of turbid pond water with a high content of Soluble Reactive Phosphates (SRP) in a constructed wetland. Pot experiments with the individual plants showed the removal of SRP from the pond water at a ...

Geochemical modelling of the evolution and fate of metal pollutants arising from an abandoned gold mine tailings facility in Johannesburg
Analytical techniques were combined with geochemical modelling to study the release mechanisms of pollutants from an abandoned gold mining tailings storage facility near Johannesburg. Inverse modelling of sampled tailings pond water and experimental single extractions using various solutions indicated which combination of naturally occurring leaching solutions were likely to give rise to the ...

Fluoride levels in drinking water and other surface water of an industrial area belt of Orissa State in India
The fluorosis problem along with endemicity characterised by high degree of industries releasing fluorides into the environment was studied to quantify the fluoride levels in the different water sources. The analysis showed that out of 17 tube wells monitored, three (17.65%) showed higher fluoride levels. Among the open well monitored, 17 (58.54%) had higher fluoride content out of 41. The ...

Effect of arsenic on soil, plant and foodstuffs by using irrigated groundwater and pond water from Nadia district, West Bengal
The total arsenic withdrawn by the seven shallow tubewells used for agricultural irrigation in the arsenic-affected areas of Nadia district per year is 3851 g (mean: 550 g, range: 118?2410 g). When the amount of arsenic in the groundwater is high, it has been observed that the levels of arsenic in agricultural land soil and plants are correspondingly high. Arsenic concentration in paddy field ...

Diatoms for assessing the ecological condition of inland freshwater bodies
The ecological responses of diatoms to pollution and nutrient enrichment, caused by domestic and municipal sewage, in the five fresh water ponds have been examined. It was observed that diatoms were completely absent in P3 and some species were also absent in P1 and P2. Similarly, diatom diversity was lower in P1 and P2 than in P4 and P5. However, diatom abundance was higher in P4. The Biological ...

Drinking water contributes to high salt consumption in young adults in coastal Bangladesh
Increasing salinity of freshwater from environmental and anthropogenic influences is threatening the health of 35 million inhabitants in coastal Bangladesh. Yet little is known about the characteristics of their exposure to salt (sodium), a major risk factor for hypertension and related chronic diseases. This research examined sodium consumption levels and associated factors in young adults. ...

Sulfide Tails Management Within the Framework of Sustainable Development in Mineral Sand Mines—The Case Study of Sierra Rutile Ltd.
The study discussed here assessed Sierra Rutile Ltd.’s (SRL’s) water-cover sulfide tails management method. Monthly and quarterly water samples from SRL’s Sulfide Tails Pond (STP), Total Tails Pond (TTP), and the Titan Domestic Pond (TDP) were analyzed for 15 months. Results indicated acceptable quality for the STP. From Student’s t-test analysis, it was found that the ...

Effective natural organic matter removal in pond water by carbon nanotube membrane with flocculation/adsorption
A carbon nanotube (CNT) ultrafiltration (UF) membrane was applied to natural organic matter (NOM) removal in pond water treatment. The source water was pretreated by flocculation and/or adsorption prior to the UF process to alleviate permeate flux decline and improve NOM removal efficiency. The performance of a commercial polyethersulfone (PES) UF membrane was compared to evaluate that of the ...

Effects of silver nanoparticles to the freshwater snail Physa acuta: The role of test media and snails' life cycle stage
Silver nanoparticles (AgNP) are highly used worldwide, which will most likely lead to their release to the environment and subsequently increase environmental concentrations. Therefore studying AgNPs' deleterious effects to organisms is crucial to understand their environmental impacts. The freshwater snail Physa acuta was chosen to evaluate the potential deleterious effects of AgNP and ...

Characterization of water pollution in drainage networks using continuous monitoring data in the Citadel area of Hue City, Vietnam
In the Citadel area of Hue City, drainage systems that include canals and ponds are considerable sources of fecal contaminants to inundated water during the rainy season because canals and ponds receive untreated wastewater. It is important to investigate the characteristics of hydraulics and water pollution in canals and ponds. At the canals and ponds, water sampling was conducted during dry ...

How to Find a Leak in a Pond Liner
Finding a leak and fixing it in a pond liner can be tedious but in this guide well go step by stem from identifying to fixing the leak. Leaking concrete ponds, rubber pond liners, plastic liners can all be repaired. In ponds there will always be some water loss due to evaporation and even sometimes splashing from water features. Damage to pond liners usually are caused by external sources. ...

PMMA-titania floating macrospheres for the photocatalytic remediation of agro-pharmaceutical wastewater
Antibiotics such as tetracycline are used on a large scale in agriculture, and can become concentrated in wastewater lagoons that are used in conjunction with confined animal feeding operations. Solar-illuminated titanium dioxide can be used to photocatalytically degrade aqueous tetracycline, but its application in a lagoon environment requires that the photocatalyst be supported on a ...

Monitoring heat exchanger leaks in Paper plant - Case Study
The Situation A paper plant in the Eastern United States uses 500 gallons per minute filtered pond water for cooling lubricating oil in its paper line. The resulting warmed water is diverted to an onsite pond. Because the water is used to cool lubricating oil, the plant could not reuse the water in its pulping process for fears of possible oil contamination of the paper pulp. The Problem The ...
