“…For sites where the transport distance is much shorter, the composting scenario would come out much better. This outcome is in accordance with what has been earlier reported by Suèr et al (2004) [11] and Toffoletto et al (2005) [9], that transportation is a key element when choosing between in-situ and ex-situ remediation technology.…”

“…Lemming et al [5] reviewed 12 different studies on life cycle assessment of soil and groundwater remediation in 2009. Similarly Suèr et al [11] in 2004 made a literature review on LCA for site remediation. A common conclusion from these reports is that transport of excavated soil often contributes significantly to the total environmental impact of any off site remediation technology, especially at longer transport distances.…”

Small Scale In-Situ Bioremediation of Diesel Contaminated Soil – Screeing Life Cycle Assessment of Environmental Performance

Spillage of diesel oil and other petroleum products is a commonly creating need for site remediation of contaminated soils. In Sweden the most common remediation action is excavation of the contaminated soil and off site biological treatment by composting. However, a number of small sites spread out in rural areas end up low on priority lists, and will not be attended to within foreseeable future if ever. For such areas a low cost, easy to apply remediation techniques would be of interest. Enhanced bioremediation of diesel contaminants in soil by whey addition has been demonstrated in lab scale. Whey is a by-product from cheese production. A first pilot remediation trial on an actual site in Gäddede, County of Jämtland, was started the summer of 2010. Using this site as a case study a screening life cycle assessment model has been set up. The goal of the study was to investigate the environmental performance of the whey method, to benchmark the whey method toward the excavation and composting practice and to identify environmental hot spots in the whey treatment life cycle. The study aims at establishing if further work should be put into developing the method, or if the environmental performance is such that the whey method should be abandoned. It should be noted that even with a slightly worse environmental performance compared to other remediation alternatives whey treatment could still be of interest, since the small scale sites in rural areas we talk about here otherwise most often would not be attended to. Results from the screening life cycle assessment indicate a rather good environmental performance of the whey method, partly depending on impact category considered. For the whey method, impacts from farming activities in the milk production chain allocated to the whey give significant contributions. Transportation gives important impacts from both the whey method and the excavation and off site composting, thus logistics should always be considered and optimized. The whey onsite treatment could be an interesting alternative for bioremediation especially at sites that would not otherwise be treated, due to small size or remote location.

“…In a literature review, Suér et al [11] illustrate that the result of LCA is highly dependent on the method used and that the choice of impact categories heavily affects the outcome of an LCA study. An updated overview (Table 2) of case studies dealing with LCA of the remediation of contaminated sites illustrates the high variation in impact assessment methods that have been used over the last [18] Industrial site contaminated with sulfur…”

“…Besides primary impacts, associated with the state of the site and secondary impacts, associated with the site remediation itself [12], LCA for contaminated site management should also account for tertiary impacts, associated with the effects of the reoccupation of the site [13]. Therefore, different scenarios could be considered and the collection of additional data concerning temporal and spatial effects should be integrated into the evaluation of contaminated sites [11]. For example, Cadotte et al [14] considered two different remediation scenarios: one based on a fast treatment time and another one based on a low environmental impact.…”

When evaluating remediation technologies for contaminated soil and groundwater, the beneficial effect of the remediation, namely cleaner soil and groundwater, are mostly emphasized without consideration of the environmental impact of the remediation activities themselves. Nevertheless, practitioners and decision makers can rely on a broad range of decision tools that can help them to achieve a better balance between economic, social and environmental health aspects of contaminated land remediation. A holistic approach for the management of contaminated land should ideally include an assessment of the environmental risk of the contamination, an assessment of the environmental, social and health impact of the remediation process and a cost-benefit analysis of the remediation project.A life cycle framework, including a life cycle management (LCM) approach structuring environmental activities and life cycle analysis (LCA) for a quantitative examination, can be helpful for the selection of site remediation options with minimum impact on the ecosystem and human health. During the last 10 years, several instances have emerged in which a life cycle approach has been applied to the remediation of contaminated sites. Besides addressing the environmental impact of the remediation activities for a specific site, attention should also be paid to the consequence of reintroducing a remediate site into the economy. From a legal point of view, there should be ways to encourage the use of sustainable remediation technologies, together with a disconnection of treated soils from the definition of waste. Finally, the focus should move from remediation, whether sustainable or not, to the prevention of soil contamination..

“…However, the control of the operation is more difficult and depending on the permeability of the soil and soil stratification, the operation may results in very poor results. On the other hand, ex-situ technologies permit a better control of the operation, and the remediation results are not very affected by some soil characteristics as permeability and stratification [17][18][19].…”
