Implementing a radiation monitoring program at a solid waste landfillCrail, Scott Allen 03 May 1999 (has links)
More and more, modern society is incorporating the use of radioactive materials into everyday uses. And with society using more radioactive materials, the odds of it being accidentally disposed of into the solid waste stream increases.
There are several radiation systems available which market themselves as being complete and "ready to go". While it is true that a person could purchase one of these systems and would have coverage of the landfill, such a system does not provide the necessary education, response and liability protection programs. Indeed, it would be feasible to foresee a scenario where installing a systems could lead to an increase in liability and employee problems.
As a result, Coffin Butte Landfill worked with the author to establish a complete radiation monitoring program. This program encompasses everything from installment of the system to employee education and training. It also examined the myriad and murky depths of federal and state regulation dealing with solid and radioactive waste to help the landfill set an acceptance policy and minimize liability. This led the author to the belief that the combination of federal and state
regulations imply a requirement for landfills to have a working radiation monitoring program.
Future government action remains uncertain as pertaining to a requirement for landfills to maintain a radiation monitoring system. Indeed, current state regulations are out of sync with federal regulations regarding acceptable public exposures. It is hoped that, with this study's help, Coffin Butte Landfill and Oregon State University will continue with the established relationship and be prepared to respond to regulation changes. / Graduation date: 1999

The use of wetlands as a wastewater treatment technique: a literature reviewFillmore, Gary Boyd 26 January 2010 (has links)
<p>As the database of information for constructed
wetlands grows, the benefits and limitations of this
alternate wastewater treatment technology will be better
understood. Based upon the results for numerous field and
case studies, wetlands treatment can be highly successful
at a relatively low cost. This technology appears to hold
considerable promise for its technological capabilities
plus it is widely applicable. Wetlands treatment has been
successfully used to treat domestic wastewater, industrial
wastewater, leachate, acid mine drainage and stormwater.</p> / Master of Science

Talking garbage: a study of local opposition, waste management and community consultationCollins, Kathryn L, University of Western Sydney, Hawkesbury, Faculty of Environmental Management and Agriculture January 1998 (has links)
Every attempt by the NSW State Government to site waste treatment and disposal facilities has been met by opposition from local communities. Increasing interest is being shown in community consultation and public participation in the decision-making processes concerning the siting of waste management technologies. This thesis examines the rationale behind, and potential of, community consultation through an examination of two case studies. The thesis concludes that the reasons and remedies for local opposition typically given by experts and regulatory authorities are flawed. The engineering concerns which have dominated approaches to choosing and siting waste management technologies are of little consequence to the way in which communities judge whether the facilities pose an acceptable societal risk. The issues of concern to communities include the legitimacy of the decision-making process, the relative fairness of the decision to site, and whether the institutions responsible for managing and operating the technologies are trustworthy. If waste management technologies rely on local acceptability for their siting, the approach taken to resolve the waste problem must include societal as well as engineering concerns in the design of courses of action to manage the risk. / Doctor of Philosophy (PhD)

Denitrification of leachate using domestic waste at different levels of stability : simulations in batch test.Sawyerr, Nathaniel O. 01 November 2013 (has links)
Disposing of waste on land has been a method practiced by many countries because it is
relatively inexpensive. This has led to the fast increase of landfilling option which is also due to
increase of waste generation, resulting in the increase in the urgency of investigating cheap
measures of treating wastewater (leachate) that is generated from landfills prior to its discharge
to the environment. After the application of the process of nitrification using Sequencing Batch
Reactor (SBR) such as is applied at Mariannhill landfill site, Durban, the treated leachate still
contains high level of nitrate ranging from 500 – 2000 mg/ℓ, which greatly exceeds the discharge
limit of 12 mg/ℓ. Ex-situ bio-denitrification has been used widely around the world in various
technological applications (SBRs, anaerobic trickling filters, etc.) that generally employ
expensive chemicals. Hence the need to investigate the removal of nitrates using in-situ biodenitrification
processes using readily available carbon sources such as fresh commercial
garden refuse (CGRraw) and composted commercial garden refuse (CGR10). Both carbon
sources were mixed with waste that had been treated for 8 weeks (Cell 1) and 16 weeks (Cell 2). The aim of this study is to determine the viability of pre-treated general waste at different
degrees of stability (carbon contents) as carbon sources for in-situ bio-denitrification in landfills.
The focus was mainly on determining the suitability, the kinetics and the performance of the different substrate.
The suitability of the substrates to perform denitrification was assessed based on the carbon
content and carbon to nitrogen ratio in the substrate. On establishing suitability, the kinetic rate
of denitrification was assessed for each substrate. The kinetics analysis was based on the time
taken for full denitrification to occur and the concentration of the byproducts of the denitrification process such as Ammonia.
Characterization tests were performed to determine the suitability of the substrates to be used
as carbon sources for denitrification. In situ denitrification processes were simulated at smaller
scale in the laboratory using anaerobic batch reactors, with biologically treated leachate and
seeded Treated leachate from the Sequencing Batch Reactor. Batch tests were conducted at a nitrate concentration level of 500 mg/ℓ. The combination of 8 weeks treated waste with Fresh Commercial Garden Refuse (Cell 1 + CGRraw) and with Commercial Garden Refuse (Cell 1 + CGR10), respectively, provided the
most suitable substrates for denitrification as they contained the highest carbon content as well
as relatively high carbon to nitrogen ratio (C:N) . Although the 16 weeks treated waste together
mixed with Commercial Garden Refuse (Cell 2 + CGR10) had the lowest C:N ratio, this could be
due to a lack of homogeneity within the sample. The results of the batch tests confirms that 8
weeks treated waste (Cell 1) and 16 weeks treated waste (Cell 2) substrates were both too
stable and contained too little carbon to attain full denitrification. In addition to the inability to
attain full denitrification, Cell 2 leached out nitrate of approximately 500 mg/ℓ NO3-N back into
the batch. The batch test results showed that the cells substrates augmented with CGRraw and CGR10 achieved positive results as full denitrification was achieved within a maximum of 7 days for Cell 1 and 14 days for Cell 2. / Thesis (M.Sc.Eng.)-University of KwaZulu-Natal, Durban, 2011.
