Enjoy the summer time and looking forward to meeting you at one of the events and in Lima.
UNEP Outlines Integrated Actions to Tackle Soil Pollution in Preparation for UNEA-4
The 3rd session of the UN Environment Assembly (UNEA-3) adopted a resolution requesting
member States and relevant UN bodies to explore ways to address soil pollution in a more
integrated manner. In this resolution 3/6 titled,
‘Managing Soil Pollution to Achieve Sustainable Development’,
UNEA called for a report on the extent and future trends of soil pollution,
considering both point source contamination and diffuse pollution and on the risks and impacts of
soil pollution on health, the environment and food security, including land degradation and the
burden of disease resulting from exposure to contaminated soil.
The report also draws attention to a complementary UNEP-led global nitrogen assessment
project funded by the GEF that will focus on the impacts of forms of reactive nitrogen in the
environment, including within soils.
Assessment of the global status and regional trends of soil pollution
The Global Soil Partnership, with the support of its Intergovernmental Technical Panel on Soils
and the Regional Soil Partnerships, and in collaboration with UN Environment and WHO,
proposes to conduct a detailed study of soil pollution worldwide by collecting basic information
such as policies to prevent, control and remedy soil pollution; the number and extent of polluted
sites; the identification and location of potentially polluting activities. This approach will help to
better understand the problem of soil pollution on a global scale and identify the main knowledge
and legal gaps.
The purpose of this survey is to gather data and information which will help build a global picture
of soil pollution and identify gaps and areas of intervention, will trigger national, regional and
With the feedback gained through a questionnaire sent out in March 2019 a quality report is
foreseen that reflects the regional and global status of soil pollution. Findings and
recommendations made in the assessment will be presented in a report at the 5th session of the
United Nations Environment Assembly UNEA-5 (March 2021) where decisions will be made on
future actions to address soil pollution.

NEWS FROM NICOLE
NICOLE Fall Workshop 2019 – Call for Abstract
The NICOLE fall workshop on risk assessment
(European Policy and best practice application) will be held from 7 – 8 November 2019 in
The host country for the workshop, Poland, has recently introduced risk-based legalisation. This
presents an ideal opportunity for the network to reflect on the current status of risk assessment
policy across Europe.
Are risk-based policies becoming more or less common?
How does this sit alongside the objectives of the EU directives that are relevant to soil and groundwater contamination?
Do we have examples of progressive risk assessment policy approaches being applied?
The use of pesticides to increase agricultural production continues to be an important topic for
environmental research. Once applied to the field, pesticides can be degraded by the influence of
physical, chemical and biological factors, volatilized, adsorbed by soil colloids and transported
through surface runoff and leaching. Bentazone, terbuthylazine, and S-metolachlor are important
herbicides applied to maize and other crops to control pre-emergence or early post-emergence
broadleaf and grass weeds. The degradation and leaching of those herbicides in the soil-water-plant-system
were investigated using a weighable, monolithic lysimeter.
The leachates were analysed over a five years period. In conclusion, S-Metolachlor and the
metabolites Metoalchlor-ESA, Metolachlor-OA, as well as Desethyl-Terbuthylazin where
detected. Whereas bentazone, terbuthylazine, N-methyl-bentazone, and 2-hydroxy-terbuthylazine
were not detected in leachate. In soil, the metabolisation was detected in varying soil depths.
The importance of analysing both parent compounds and metabolites on a long-term scale was
demonstrated to better understand the environmental fate and transport.

Call for Interest: Organisations interested to host SustRem 2020
Sustainable Remediation of contaminated sites has been continuously evolving in the last decade
as a response to a growing global, public and industry environmental awareness, social pressure
and resource scarcity. During this timeframe, broader, more holistic concepts have now
developed that consider sustainable land management and stewardship.
Under the co-ordinated organisation led by internationally acknowledged entities (NICOLE,
COMMON FORUM, CL:AIRE and various SuRF chapters worldwide - now grouped under the
International Sustainable Remediation Alliance, ISRA), the first SustRem Conference was held in
Denmark in 2009, followed by Austria in 2012, Italy in 2014, Canada in 2016 and Brazil in 2018.
A Call for Interest to host the next Sustainable Remediation conference, likely in 2020/21 is
launched. Potentially interested organisations (Universities, National or international associations
and fora) should submit a Letter of Interest by no later than August 30th 2019, outlining: proposed
conference inspirational values and programme, organising committee, venues and critical
logistical aspects, synergy with other events, expected participation, partnerships and supporting
Following selection of received applications (to be based upon evaluation of the above aspects),
the successful hosting organisation will be accompanied by standing members of the SustRem

DOCUMENTS OF INTEREST
TECHNOLOGY GUIDE (SOIL): BIOREMEDIATION
Cooperative Research Centre for Contamination Assessment and Remediation of the Environment (CRC CARE), Australia. 44 pp, 2018
The purpose of this guide is to provide information on bioremediation as a treatment technology
for the remediation of contaminated sites to assist with selection of remediation options. The
document contains information to inform remediation planning and aid compilation of a
remediation action plan. While soil, groundwater, and vapor are all able to be bioremediated,
this document predominantly provides guidance on the application of bioremediation as a
remediation technology to treat contaminated soil. This guide is primarily intended to be
utilized by remediation practitioners and those reviewing practitioner's work; however, it can
be utilized by other stakeholders within the contaminated sites industry, including site owners,
proponents of works, and the community.

CL:AIRE technical bulletins describe specific techniques, practices and methodologies currently
being employed on sites in the UK. This bulletin provides a summary of per- and polyfluoroalkyl
substances (PFASs) and highlights approaches to manage risks and liabilities associated with
their impact to the environment.
STRENGTHENING SOCIAL-ENVIRONMENTAL MANAGEMENT AT CONTAMINATED SITES TO BOLSTER GREEN AND SUSTAINABLE REMEDIATION VIA A SURVEY
D. O'Connor, D. Müller-Grabherr, D. Hou
Chemosphere, Volume 225, June 2019, Pages 295-303
The Green and Sustainable Remediation (GSR) movement demands informed, integrated, and
holistic management of contaminated sites. As such, GSR may become increasingly relevant
in developing countries such as China, where vast areas of contaminated land require
clean-up. Among other efforts, the World Bank together with China's Foreign Economic
Cooperation Office is facilitating GSR adoption through the development of a guideline
on social-environmental management. However, there are no existing studies that have
considered how the established remediation industry perceives its effectiveness in
addressing the various social-environmental management aspects, or how certain aspects
have rooted. Without this information, it may be difficult to guide social-environmental
practice forward, or introduce GSR into developing remediation markets with any precision.
Therefore, a questionnaire survey of remediation participators was undertaken with principal
component analysis (PCA) applied to the data to help group the various aspects. The PCA
extracted two components for environmental management, ascribed to: (1) on-site/local
impacts; and, (2) widespread impacts, and three social management components, ascribed
to: (1) community inclusion; (2) economic gain; and, (3) health, safety, and welfare. It
was found that the aspects with which the industry are most familiar historically are
generally dealt with more effectively than those that have only recently been introduced
by the GSR movement. In particular, bolstering the management of widespread environmental
impacts and giving greater regard to the economic gain of remediation, may be beneficial.
In developing countries, public engagement is often very limited, necessitating improvement
in remediation policy and guidance.
IN SITU CHEMICAL OXIDATION: LESSONS LEARNED AT MULTIPLE SITES
Pac, T.J., J. Baldock, B. Brodie, J. Byrd, B. Gil, K.A. Morris, D. Nelson, J. Parikh, et al. Remediation 29(2):75-91(2019)
This paper compiles a detailed set of in situ chemical oxidation (ISCO) lessons learned pertaining
to design, execution, and safety based on global experiences over the last 20 years. While the
benefits of a correct application are known, history also provides examples of a variety of
incorrect applications that provide an opportunity to highlight recurring themes that resulted in
failures. This paper combines a thorough discussion of lessons learned through decades of ISCO
implementation throughout all aspects of ISCO projects with an analysis of changes to the ISCO
remediation market. By discussing the interplay of these two themes and providing recommendations
from collective lessons learned, the future of safe, cost-effective, and successful applications
of ISCO can be improved.
INSTALLATION, OPERATION AND STARTUP OF AUSTRALIA'S FIRST REGENERABLE RESIN SYSTEM FOR PFAS REMOVAL
Woodard, S. | RemTEC Summit, February 26-28, 2019, Denver, Colorado
A 200-gpm regenerable ion exchange (IX) resin system was installed in spring 2018 to remove PFAS
from groundwater at the Royal Australian Air Force Base Williamtown. The system includes
pretreatment filtration to remove suspended solids, IX resin to remove fouling agents
(including iron and natural organic matter), specialized IX resins for PFAS removal, and
an in-vessel regeneration process used to strip PFAS from the IX resin. Influent
concentrations to the full-scale system range from 18 to 410 ?g/l. More information:
