Extract of sample "Are Perfluorochemicals Widespread in Biosolids"

Contamination from landfill leachate may also be a contributing factor, though there is little to no data currently available to verify this possibility.
The identification of perfluorinated chemicals in wastewater is not entirely unexpected, even if an ultimate source cannot be identified. A 2008 EPA workshop presented data demonstrating the prevalence of these chemicals in wastewater treatment plants, especially in urban areas. The abundance of perfluorochemical precursors, i.e. any chemical which precedes and can be modified into a perfluorochemical, used in industrial work is likely to simultaneously contribute to the observed pollution and stymie efforts to identify individual sources.
Scientists and government officials have been largely unprepared for surveying perfluorinated chemicals in sewage sludge and have only recently begun this investigation. Currently, there is a lack of representative data on perfluorochemicals in biosolids. Read More

Discuss the benefits and environmental implications of applying composts and other organic amendments to agricultural land

... (PTEs) such as heavy metals. There is a requirement for long-term research on sludge use on agricultural land, the slow evolution and difficulty in prediction of the possible build-up of toxic elements in soil, state Gaskin, Brobst, Miller et al (2003). Further, sludge benefits to farmers should be assessed on a crop rotation basis, taking residual impacts on subsequent crops into consideration. These may be considerable even in the case of mobile elements such as Nitrogen, assert Binder, Dobermann, Sander et al (2002). The characteristics and performance of sludge can be markedly changed through treatments converting it into biosolids. Therefore, spreading techniques as well as their application rates have to be optimised... for the...

Planning for sustainable water quality

...). These projects convert wastewater to safe water that can be utilized by ordinary citizens. Industries cannot discharge waste water directly into public water treatments areas without prior purification. The pretreatment aims at reducing toxic wastes discharged into these treatment works. EPA has also developed technology-based standards for industries using POTWs to discharge their wastewater. These standards apply to industries in all states that produce effluent that may reach water bodies. Treated wastewater produces biosolids that can be used in agriculture. Treated sewage sludge is used for agricultural purposes. EPA conducted a risk assessment and established limits for use of biosolids in land...

Wastewater Pollution: Comparing Three Treatment Methods

...?Wastewater Pollution: Comparing Three Treatment Methods Wastewater comes as a result of an industrial process that has added chemicals and biosolids that are harmful to human health and to the environment. Whole ecosystems have been destroyed because of the mishandling of wastewater in the past. Three methods of treating wastewater which can be tested against one another for effectiveness and costs are the activated sludge method, the reed bed method, and a new method that has just been discovered in Australia which consists of adding hydrotalcites to wastewater or encouraging hydrotalcites that already exist in the water to form. The three methods can be compared in order to establish their effectiveness and costs as they relate... is a...

The study of process management is made all the more complex and thought provoking because of the competition of ideas between different academic and political standpoints. Added to this is the input from those who actually practice administration or management, giving us a "real world" perspective. Today, process...

A central problem addressed in the 1925 Property legislation was how to cope with the fragmentation of benefit created by the widespread use of trusts in relation to land. Discuss. How has subsequent legislation sought to deal with this enduring problem

Year of Study/Semester: Submitted: The Law of Property Act 1925 s. 205 ix) defines land as constituted by “the surface, building, or parts of buildings” and everything else that is linked to the said land and as such becomes part of that land with respect to the Latin maxim of quicquid plantatur solo, solo cedit. The Law that relates to co-ownership which primarily relates to concurrent interests in land constitutes a significant section of most syllabuses in land law. Of significant importance is the reality that co-ownership is an area of land law which has a powerful impact on the lives of ordinary individuals in the U.K. In more straightforward terms co-ownership law is always in operation when two or more people...
