AGS Laboratories Working Group – October Update

Article Laboratories by

The final AGS Laboratories Working Group meeting of the year took place on 17th October 2017 in London and the Laboratories Leader, Dimitris Xirouchakis of Structural Soils, has provided an update on the top three current issues the Laboratories Working Group are discussing.

Incorporation of the published EN and ISO standards to BS 1377, update of the chemical test methods in BS 1377 and the addition of rock testing methods to BS
Soil test methods in BS 1377:1990 are being replaced by the equivalent BS EN 17892 series. Despite the similarities, small differences exist and AGS members need to educate themselves and their clients, as the new tests will eventually appear in project specifications in the UK and potentially abroad, e.g. Middle East. Furthermore, any practical or nominal updates to BS 1377 will increase its applicability. The group believe the AGS need to adapt fast to the new technical standards being published.

Raise the profile and training and certification of laboratory technicians in geotechnical laboratories
This issue is important to the group as any effort to formalise the on-the-job training received by site and laboratory technicians, as is the case for engineers and geologists, will improve the services offered. The training can be improved by offering or supporting online training by partnering with other professional organisations or universities.

To increase participation in the Laboratories Working Group

Member participation of Laboratories Working Group meetings has waned recently even though many AGS member companies have laboratories. Testing services are an important component to AGS activities and strong participation to the Laboratory Working Group should reflect that.

PCBs: What are they, and which Suite do I need for my Site Investigation?

Article by

By David Bowen, Senior Chemistry Supervisor at TerraTek

There are 209 Poly-Chlorinated Biphenyl (PCB) congeners, named in simple terms using BZ numbers, ranging from BZ#1 (2-Chlorobiphenyl) to BZ#209 (2,2’,3,3’,4,4’,5,5’,6,6’-Decachlorobiphenyl).
Of these 209 congeners however, only the EC7 and WHO12 congeners are routinely tested for by commercial environmental testing laboratories. So why only these 18 congeners (one congener, BZ#118, appears in both suites) you may ask? And what about the other 191? Furthermore, which of these PCB suites would be the most suitable for your site investigation?
Poly-Chlorinated Biphenyls (PCBs) are Biphenyl organic compounds, C12H10, with the hydrogen atom substituted by a Chlorine atom. There can be from one to ten substituted atoms, C12H10-nCln (where n= 1 to 10). Depending on the number and position of the Chlorine atom/s around the Biphenyl, denotes which congener the PCB is, and named accordingly.

Figure 1. PCB structure

Commercial production of PCB mixes (e.g. Aroclors) began in the early 1930’s up until the 1970-80’s when they were phased out due to environmental concerns. PCBs are particularly useful for their electrical insulation properties, low flammability, and stability. Subsequently, they were used in transformer oils, coolants, paints, and flame retardants, to name just a few. Unfortunately, also due to these properties, they pose a significant risk to the environment, and were classified as one of the initial 12 Persistent Organic Pollutants (POPs) under the Stockholm convention1. According to the European Food Safety Agency (EFSA) 2 however, only 130 of the 209 PCB congeners have been reported in commercial Aroclor mixes and environmental samples.
PCBs can be sub-divided into two categories; the coplanar and non-coplaner congeners.
The co-planer congeners either have a single or no Chlorine atoms substituted for a Hydrogen in the ortho position (figure 1. A single or no Cl in position 2, 2’, 6 or 6’) on the phenyl rings. They are dioxin like in character, there are twelve of them, and are recognised by the World Health Organisation (WHO) as being used to determine Toxicity Equivalent Factors (TEFs) in relation to the most toxic dioxin 2,3,7,8-Tertrachlorodibenzo-p-dioxin (TCDD). Health risks include reproductive and developmental toxicity, and / or immune suppression.3
The non-coplaner congeners have more than one Chlorine atom substituted for a Hydrogen in the ortho position on the phenyl rings. These congeners are considered to be less toxic, as they do not bind to the aryl hydrocarbon receptor which causes the health effects associated with the dioxin like PCBs. However, they are still toxic, and have shown to elicit neurological, endocrine and immunological effects, and are 4% more abundant in soil and 5% more in food, than the dioxin-like PCBs.3
So which PCB suite would you select for a site investigation?

Figure 2. Site investigation

A WHO-12 PCB suite is used to monitor the TEFs of dioxin-like-PCB compounds for a site investigation of human health risk assessments. If a site analysis was restricted to only the WHO-12 PCBs however, it is worth remembering that they are less abundant in the environment than the non-dioxin-like PCBs, and only make up by weight <4% of the commercial Aroclor mixtures produced. Therefore, even if a negative result for the WHO-12 PCBs is received, the site could still potentially contain a significant amount of the non-dioxin-like congeners. The PCB 7 suite was initially selected by the International Council for the Exploration of the Sea (ICES) as a PCB screen for monitoring biota and sediment samples, and became a mandatory requirement of the OSPAR Co-ordinated Environmental Monitoring Programme (CEMP).4 Subsequently, this became the recommended suite by the European Union Community Bureau of Reference for monitoring PCBs, and was also specified and a limit assigned in the UKs Landfill Directive for Waste Acceptance Criteria. These seven PCBs were selected as indicators as they make up ~20% by weight of PCBs in commercial mixtures3, they have a wide chlorination range, and one dioxin-like congener is included (BZ118). They are more likely to be found in environmental samples and at higher concentrations compared to the WHO-12.
Figure 3. A PCB 7 suite is routinely requested for sites containing Electrical sub-stations and transformers.

To cover all the PCBs present, an Aroclor matching total PCB suite could be performed. This covers all PCBs present and are quantified against the nearest matching Aroclor standard, although does not identify individual congeners and LODs are very high compared to the PCB7 and WHO12 screens.
So which suite should you select? Ultimately, the historical use of the site and the subsequent risk assessment of it would dictate the choice. Regardless of this however, the advantages of requesting a PCB-7 and a WHO-12 together cannot be underestimated in providing a full indication of the PCB contamination present at trace levels if any. Alternatively, if only a PCB-7 suite was requested, and the dioxin-like-congener (BZ#118) was found, an additional WHO-12 PCB test would be advantageous in assisting in the risk assessment process.

Explaining Laboratory Proficiency Testing

Article Laboratories by

by John Masters, Director of Geolabs

The use of Proficiency testing and Interlaboratory comparison schemes is an invaluable tool for laboratories to assure the quality of their test and calibration results. Often seen as simply a necessity to satisfy an accrediting body, the benefits of participation in proficiency testing and interlaboratory comparison schemes are greatly underrated.

The ILAC publication ‘Benefits for Laboratories participating in Proficiency Testing Programs’ highlights that ‘the basic purpose of proficiency testing is to assess performance of laboratories for their conduct of specific test, measurements or calibrations. Many laboratories operate in isolation from other laboratories and do not have ongoing opportunities to compare their data with others. Without such opportunities there are risks that a laboratory’s data may have errors, biases or significant differences compared to similar laboratories.

Proficiency testing provides an opportunity to undertake such comparisons and to have an independent appraisal of the laboratory’s data compared to reference values (or other performance criteria) or to the performance of similar laboratories. The results from such participation provide laboratory managers with either a confirmation that the laboratory’s performance is satisfactory or an alert that investigation of potential problems within the laboratory is required’.

As defined, Proficiency Testing (PT) is generally run by an independent third party and allows laboratories to objectively monitor the reliability of their test results by the use of standardised test materials, whereas Interlaboratory comparisons (ILC’s), when performed in accordance with ISO/IEC 17043:2010, require the measurement or test of test items in predetermined conditions by two or more laboratories.

All laboratories accredited to ISO/IEC 17025(E) : 2005 are required to have procedures in place to monitor the validity of test results (and calibrations) undertaken.
Clause 5.9.1 of ISO/IEC 17025(E) : 2005 states that:
‘The laboratory shall have quality control procedures for monitoring the validity of tests and calibrations undertaken…. This monitoring shall be planned and reviewed and may include, but shall not be limited to;
a) Use of certified reference materials
b) Participation on interlaboratory comparison or proficiency testing programmes
c) Replicate testing
d) Retesting of retained items…’

Whilst ISO/IEC 17025(E) does not stipulate a mandatory requirement for accredited laboratories to participate in proficiency testing, it recommends that laboratories participate in quality assurance schemes such as interlaboratory comparison or proficiency testing.

However, Accrediting Bodies (UKAS for the United Kingdom) ARE required to ensure that ‘its accredited laboratories participate in proficiency testing or other comparison programs, where available and appropriate, and that corrective actions are carried out when necessary’(clause 7.15.3 of ISO/IEC 17011:2004).

The UKAS policy on proficiency testing is specified within UKAS Technical Publication TPS47 – UKAS Policy on Participation in Proficiency Testing, which states that:
‘4.1 all accredited laboratories shall participate in PT/ILCs where such schemes are available and relevant to their scope of accreditation’.

In August 2013, AGS produced a Position Paper (, in which the AGS highlighted the necessity for proficiency testing to promote best practice and improve professional standards in the geotechnical & geo-environmental laboratory community.

Geolabs Limited has been running a Proficiency and Interlaboratory Comparison Testing Scheme (PICTS) since 2005. The Scheme is run every other year although there have been some years where ‘mini-schemes’ have also been run to accommodate certain specific tests and requirements.

The 2017 Scheme was limited to UK laboratories only, initially for 16 BS1377 geotechnical and chemical tests. A further 8 tests were requested for inclusion, but only 4 attracted sufficient interest to be included. Therefore 20 tests were included in the 2017 scheme.

51 laboratories fully participated in the 2017 Scheme. Each participating laboratory was provided with a unique Participant ID, known only to them to maintain confidentiality at all times.
Four types of standardised material were used in the Scheme, from sandy silty clay to very sandy gravel, all prepared from documented procedures before being sent to participating laboratories.

When all participant test data is received, each participating laboratory is provided with a report with tabular and/or graphical reporting formats, and statistical analysis of each test with the Participant ID being their unique laboratory number.

The 2017 scheme report will be issued once data from all of the participants has been received, collated and analysed. It is envisaged that the report will be issued to all participants, UKAS and to Ground Engineering magazine by end November.

Participation in Proficiency Testing and Interlaboratory Comparison schemes is not just an accreditation requirement, it is essential for any laboratory looking to demonstrate technical competence and to provide confidence in the quality, reliability and integrity of the test data they produce.

Not all Office Insurance is the same

Article Loss Prevention by

AGS asked Griffiths and Armour to write a note for AGS members regarding Office Insurance.

Not all Office insurance is the same
On a daily basis, professional consultants find themselves drawn into contractual discussions with their clients, contractors and other professionals.

Often as part of this there are various insurance requirements and obligations placed on professionals that can pose a challenge.

Most professional construction consultants procure a combined insurance policy, more often known as an Office policy. Such a policy would usually provide coverage for the consultant’s material property, pecuniary assets as well as their primary liability risks of Employers’ and Public Liability. A separate Professional Indemnity policy is also essential.

Where things can become less clear is when consultants are appointing sub-contractors themselves and often accepting responsibility for them under contract.

On a traditional Office policy, such an undertaking can take the consultant beyond the bounds of their policy.

Why is this?
Insurers have an expectation of the policyholder’s activities based on the business description in the policy and the other information they know about the insured. The traditional Office policy is designed for risks that are office based but is often inadequate to deal with the realities of a construction consultant’s business activities, especially when this involves any manual work or work on sites.

It is for this reason that Griffiths & Armour developed the Workspace Plus insurance product. The intention was to develop Office insurance such that it would respond to the needs of construction professionals enabling them to run their businesses without the uncertainty that the above scenario can cause.

The Workspace Plus policy is specifically designed with Engineers, Surveyors and Architects in mind and provides cover for the following situations that often fall outside of a traditional Office policy:

• Visits to and work on construction sites
• Manual work undertaken by the consultant as part of the provision of their professional services
• Responsibility for sub-contractors on site subject to confirmation of their insurance
• Professional services associated with hazardous activities e.g. diving, abseiling, rail side, and mining
• Fulfilling the role of the main contractor

No two companies ever have exactly the same requirements and it is important to know that your insurer understands your business and the activities that you undertake to ensure that your insurance coverage has been properly tailored to your exposures.

If you have any queries or concerns regarding your current arrangements and would like an independent review, please contact:
