Environmental remediation

early 2006. PS2 generated revenue by securing service "contracts" for the treatment of contaminated soil or on a "fee­ for-service basis," wherein small quantities of contaminated soil were accepted from customers. Its eustomer base comprised environmental service companies, utility companies and general industry. The number and size of contracts obtained each year for contaminated soil varied and depended on the funding that customers had budgeted for remedial projects. PS2 went public in 2007 through

material exchanges, and ‘living technologies’”. Later on, the chapter called Synthetic Geology by Geoff Manaugh, talks about future possible applications to Beesley’s works like new soil deposits, new agricultural fields, and new landscapes, landfills remediation, archeological excavation and the possibility of colonizing distant planets. The last chapter of this section, Liberating the Infinite Architectural Substance by Neil Spiller, is about liberating the attributes of the material world, both man-made

Abstract: Bioremediation is the technology which is used to clean up the environmental pollutants. Bioremediation can be introduced as an efficient and cost effective method for the cleanup of contaminated waste water. Waste water contains heavy metals like Cadmium,Chromium, Nickel, Lead, Selenium,Arsenic, and Zinc.These metals are poisonous to the human body system. These metals can be removed using this technique. Currently microorganisms are widely used in Bioremediation process, generally in

It is always difficult to remove contaminations from soils because it contains many toxic chemicals such as (Pb, As, Cu, Cd, Cr, Ni, Hg and Zn). This chemicals mixed with the soil after burning of industrial waste, electronics waste or uses of agricultural technology. Then rain water makes it seep deep into the soil and cause soil pollution. This makes it so difficult and time consuming to remove, particularly when the affected area is on a large scale. Soil is made of by two components which are

Brownfield Phytoremediation Page 2 Page 4 A Case for Industrial Hemp? Page 5 Executive Summary There are a number of reasons why we should care about brownfields. From encouraging urban sprawl through the ‘development’ of greenfields to their environmental impacts on soil, air and ground water, these properties are a drain upon the urban environment. Redevelopment of brownfields are complicated by the potential contamination of hazardous waste, heavy metals and pollution that has been left behind

ENVIRONMENTAL MANAGEMENT (ASSIGNMENT 2) BSC (HONS) CIVIL ENGINEERING AND MANAGEMENT NAME: FELIX GHANSAH MINTAH PERSONAL ID: 633104 A. ANALYSIS OF ENVIRONMENTAL IMPACT ON REMEDIATION AND REUSE OF CONTAMINATED LAND. A contaminated land is a land which contains substances that are actually or potentially hazardous to health or the environment. Land can also be defined as contaminated if only there is significant pollutant linkage. This means that, there must be: * an evidence of the presence

in many parts of the world and is a global problem. In many areas As level has crossed the safe threshold level. Large-scale groundwater pollution by geogenic arsenic (As) in West-Bengal and Bangladesh has recently promoted this element into an environmental pollutant of prime concern. Epidemiological studies have documented various adverse effects on the human population. Arsenic contaminated soils, sediments, and sludge are the major sources of arsenic contamination of the food chain, surface water

the treatment train (Gerrity et al. 2010). Certain organic contaminants of interest, including ___, tend to have long half-lives and low water-solubility, which can make traditional and natural forms of remediation ineffective. The past decade has shown that ozone can be used in the remediation of contaminated soils, primarily by in-situ ozonation systems. As mentioned previously, ozone is an unstable chemical that has a half-life of around two minutes (Dey, Rosenwinkel, Wheeler 2002). In the process
