The classical path of successful technology development starts at lab scale and is continued at pilot scale. The first implementation under realistic conditions or “demonstration” is the key to market entry. In recent years enormous efforts were invested in research and development of promising, cost efficient soil and ground water technologies. Despite of all these efforts only very few technologies received recognition at the European market. In practice, conventional technologies are still prevailing. The second part of the path was and is definitely neglected: information on successful technology implementations under real conditions is very scattered throughout Europe and mechanisms to accelerate market entry are individualistic from country to country.

The transition from site characterization to full scale remediation in many cases is a complicated and long duration process. Remediation of chlorinated solvent impacted sites has experienced a major acceleration with the discovery and advancement of knowledge in the anaerobic reductive biodechlorination processes. This presentation will communicate through a case study the benefits of molecular biology tools and statistical analysis of historical site data to develop and implement an effective remedial action plan.

Where and when the environment is degraded, there is a need and demand to restore it to an acceptable status. This need and demand will arise from an innate morality encapsulated recently in the concept of sustainability. These will be expressed through the scientific community and through public and political debate. The call for an environmental action has to be matched by the will to respond and the availability of technical and financial resources. It is crucial that the end objectives are clearly defined. For example, there may be a difference between restored environments, which is safe, as opposed to one of a regenerated pristine status. The speed of the clean up programme will be a function of the abilities of technology, the skills of operators and the establishment / organizations to take action and funding status. The degree of immediate hazard will determine priority for action (IAWQ, 1998). [pdf 11.8 kb]

A highly efficient, versatile material having dual characteristics as adsorbent and reductant, nano-scale zero valent iron (NZVI) was synthesized and tested for the removal of two most toxic and abundant groundwater contaminants arsenic (As) and trichloroethylene (TCE). The NZVI was also stabilized by Pd and non-ionic surfactant to make it mobile as a delivery vehicle NZVI (DV-NZVI) in subsurface environment. Batch experiments were performed to determine their feasibility as adsorbents and reductants for As and TCE, respectively at neutral pH. [pdf 11.5 kb]

Studies were conducted to assess the potential of fly ash-organic waste co-disposal to enhance crop production. A pot experiment using Sorghum Sudangrass (Sorghum vulgaris) was conducted under greenhouse conditions. In addition, a leaching experiment was also conducted to assess the leaching potential of certain trace elements from fly ash sewage sludge amended soils. The results indicated that biomass production of Sorghum Sudangrass was significantly increased up to 247 Mg ha-1 FA: SS mixture amendment, regardless of various ratios of FA: SS mixed amendment. The leaching study indicated that increased application rates of amendments (either alone or as mixtures) resulted in increased leaching of trace elements. Therefore, low to moderate rates of FA:SS mixture. [pdf 11.8 kb]

Risk management is a mainstream regulatory activity in 2007. Regulators now encourage operators to invest in risk critical improvements, identify and manage critical control points and apply their own resources to regulating activities deemed to pose the greatest risk. Given the broad remit of most regulatory bodies, the inherent complexity of environmental matters and the practical challenges of balancing the interests of public and regulated communities, regulators are frequently engaged in high profile and contentious issues.

The activated sludge process, in its original form or many modified forms, is the wastewater treatment method of choice for most municipal wastewater treatment facilities in the United States. Properly designed and operated wastewater treatment plants using the activated sludge process can generally meet the secondary treatment limit of 30 mg/L for both biochemical oxygen demand (BOD) and total suspended solids (TSS).
