NanoRem project seeks stakeholders views on nanoremediation

Nanoremediation is an emerging remediation technology where nanoparticles are applied in situ for the treatment of contaminated groundwater and soil. Nanoremediation processes generally involve reduction or oxidation, which in some cases may be facilitated by an embedded catalyst.

Nanoscale zerovalent iron (nZVI) is the most commonly used particle to date.

NanoRem (Taking Nanotechnological Remediation Processes from Lab Scale to End User Applications for the Restoration of a Clean Environment) is a research project, funded through the European Commission’s Seventh Framework Programme. NanoRem focuses on facilitating practical, safe, economic and exploitable nanotechnology for in situ remediation of polluted soil and groundwater.

Part of the project is to understand the future promise of iron nanoparticles/nanoscale zero valent iron (nZVI) use in remediation as a remediation technology and to understand more about stakeholders thoughts and knowledge of the technology and its future opportunities.  NanoRem has recently produced an interim 'Risk-Benefit and Markets Appraisal, Initial Exploitation Strategy and Consultation' on the use of nZVI.

This short report summarises NanoRem’s initial findings and was made available at the end of April.

NanoRem is interested to collect additional opinions from different practitioners and stakeholders about the issues raised in this report and its interim findings.  In order to do this NanoRem has created a short questionnaire where they would greatly value your input.

Please follow the link to access both the report and the questionnaire:>>>

New report: Soil and Groundwater Remediation Technologies for Former Gasworks and Gasholder Sites

CL:AIRE is pleased to announce that a report on soil and groundwater remediation technologies for former gasworks and gasholder sites is now available to download.

It is the output of a research project conducted by CL:AIRE for the Gas Distribution Network (GDN) companies. The project was funded by Wales & West Utilities (WWU) partnered with the Energy Innovation Centre.

Describing the key issues and contaminants that the GDNs are currently facing, the report identifies five main types of contaminated sites that exist on the GDNs inventory as follows:

  • General redundant sites;
  • Operationally constrained sites, containing infrastructure and live services;
  • Sites that have immediate borders with surface waters;
  • Small, remote, low value sites; and,
  • Sites that have shared source structures/part-ownership.

It describes the main soil and groundwater technologies that are currently available to treat the common contaminants associated with former gasworks and gasholder sites and categorises them as in situ, ex situ, and traditional civil engineering methods.

The report also considers which of these technologies are likely to be appropriate on the five types of sites above, but the discussion comes with an important caveat and concentrates solely on their general technical suitability.

It focuses on soil and groundwater remediation in the UK and internationally so that lessons can be learned from other jurisdictions on how different stakeholders remediate their former gasworks and gasholder facilities.

The regulatory framework of the UK is described and includes recent changes in legislation and what potential legislative impacts and drivers may impact the GDNs in the future.

It is apparent from the information gathered in the report that there are contaminants that are difficult to treat using commercially available technologies – spent oxide and gas purification wastes, coal tar and water gas tar. The report also highlights some new innovative technologies that have been developed that should be of interest to the GDNs.

HCA publishes guidance on dereliction, demolition and remediation costs

HCA recently published its updated guidance on dereliction, demolition and remediation costs (3rd Edition).

This guide helps a project sponsor understand some of the key issues when dealing with the redevelopment of previously developed land.  It also provides an indication of the likely range of remediation costs per hectare for a given past use (eg steel works) and a proposed future use (eg residential).

The revised edition of the guide includes additional guidance on pre-acquisition site investigations, as part of due diligence, and expands the remediation costs to include problems associated with demolition. 

For further information and to download the guide follow the link:

Feedback on plans for groundwater guidance closes 8th May 2015

Defra have published plans to revise guidance and web pages on groundwater protection. This forms part of ongoing work to make environmental guidance easier, quicker and clearer to understand.

You can comment on the groundwater guidance plans until 8th May 2015 at:

The plans are in two parts:

  1. Plans for Future Content - this outlines what the web pages could look like in future
  2. List of Existing Guidance – this is a list of existing guidance documents and the future intention for each. Each document is labelled red, amber or green to indicate whether it will be archived, rewritten to make it clearer and current version archived, or kept.

The smarter guidance reforms are to improve guidance so that users have a clearer understanding of their regulatory obligations. Note that existing regulations are not being changed.

NanoRem Deliverable 9.1

NanoRem (Taking Nanotechnological Remediation Processes from Lab Scale to End User Applications for the Restoration of a Clean Environment) is a research project, funded through the European Commission’s Seventh Framework Programme. NanoRem focuses on facilitating practical, safe, economic and exploitable nanotechnology for in situ remediation of polluted soil and groundwater.

NanoRem project Deliverable 9.1 (Bardos & Jones, 2015) (Download NanoRem Deliverable 9.1 from here>>>) outlines work undertaken by NanoRem which had the aim of developing an understanding of the “value proposition” (i.e. the overall promise of value to be delivered) for iron nanoparticles/nanoscale zero valent iron (nZVI) use in remediation. 

In the report, a risk-benefit appraisal has been used to give the current state of knowledge for nZVI. Following this, the report provides an overview of stakeholder workshops organised to gain opinions on the risks, sustainability, and market development factors of nanoremediation.

The outcomes of stakeholder engagement and the risk-benefit appraisal work have been incorporated into scenario analysis. Scenario analysis has been used to explore possible market developments and the factors affecting this over the short and medium to longer term.

Additionally, an analysis of strengths, weaknesses, opportunities and threats (SWOT) and how these might change over time has been used to draw some conclusions about the broad actions that might support better exploitation of nanoremediation.

The report is consultative, so there is an opportunity for its readers to provide feedback and comments about it to NanoRem via an on-line questionnaire, including their views on factors affecting the future development of the nanoremediation applications and opportunities.
