BS 10175:2011+A2:2017
Investigation of potentially contaminated sites. Code of practice. Code of practice
Status : Current Published : March 2011
OverviewProduct Details
What is this standard about?
Contaminated land contains harmful chemicals in quantities that present a risk or a potential risk to human health or the environment. When land is legally defined as ‘contaminated’ there’s a legal obligation to ensure it doesn’t present a risk to health or the environment.
The UK Government’s long term aim is to work towards a future where all the potentially contaminated land in England and Wales has been identified, assessed and made safe. Therefore this standard was created to provide recommendations and guidance on how to investigate potentially contaminated land, or land with naturally elevated concentrations of potentially harmful substances, to determine or manage any risks.
Who is this standard for?
It will be used by those with an understanding of the risk based approach to the assessment of sites as described in the Model Procedures for the Management of Land Contamination (CLR 11) [31].
Specifically, users will be experts in:
Site investigations
Land pollution
Environmental cleanliness
Dangerous materials
Toxic materials
Contamination
Pollution
Risk assessment
Project management
Sampling methods
Field testing
Laboratory testing
Chemical analysis and testing
Soil pollution
Ground water
Surface water
Gases
Why should you use this standard?
BS 10175 allows users to:
Set the objectives of an investigation
Develop a strategy for the investigation
Identify risks arising from the presence of contamination
Design the different phases of the investigation
Carry out sampling, field testing and laboratory analysis
Conduct risk assessment of a potentially contaminated site
Its recommendations and guidance are intended to ensure that the objectives of an investigation are achieved and that appropriate data for risk assessment are obtained. Note though that it’s not feasible to provide detailed guidance for every possible investigation scenario.
The results of the investigation also ought to delineate all known aspects of the site that could impinge upon or affect source-pathway-receptor scenarios defined within the conceptual model.
What’s changed since the last update?
This standard was amended to align with the nine parts of ISO 18400 that were published earlier in 2017.
BS ISO 18400-102 and -103 have become normative in this amendment, replacing parts of the BS ISO 10381 series that were previously normative in BS 10175 and which have been superseded.

Philip
As a "newcomer" I am struck by the general lack of consistency in contaminated land assessment in general. Colin Green mentioned the lack of consistency in the MCERTS "standard" which seems not to be a standard at all. I also understand that there is no standard for the TPH bandings.
Talking of which, a I right in understanding that the bandings are just used to try to identify the HC type (diesel, jet fuel, bitumen etc) or is there some other reason?

Agreed
I have no strong views either way regarding Munsell versus Norbury approach --- the key point is to benchmark the colour description to a "standard" chart for consistency --the simpler the better. Chemical analysis will be the final arbiter of contamination.
If you recall the original question that I responded to from Sophie was in regard to lack of consistency in colour description and perceived difficulties by practitioners.

Subject: RE: Soil colours
I would disagree with using Munsell colour charts as the choice of the colours is somewhat subjective and not helpful to contamination assessment. Deciding which of the 325 colours in the charts takes a lot of time for limited or no benefit. The cost of these charts is relatively high for what I believe is a hindrance to people doing soil description. Who knows what" Gley 8/5G" means and what difference is that to "Gley 6/10Y" or "5YR 5/8"? I recommend just sticking to the colours in BS5930:2015 (plus cream and orange) as there are plenty to choose from. If you want a colour chart use the colour chart on David Norbury's Website which are the Pantone colours used by professional printers, see
http://drnorbury.co.uk/wp-content/uploads/2015/08/Colour-Chart.pdf
Colours can be indicative of contamination but most of the time there is no link from colour to contaminants other than the relatively common hydrocarbon contamination or if you are in Widnes (and parts of Glasgow etc) the cream and yellowish brown colours can be Galligu. Bright colours and unusual colours can be indicators of contamination so you can add another sentence after the main description to add additional information if you think it is helpful. Unusual colours observed are usually not indicative of a specific contaminant as there is often a cocktail of different natural materials and anthropogenic materials present.
Oh, "Gley 6/10Y" is known to me as "grey" and "5YR 5/8" is "orangish brown."

Use a Munsell colour chart to avoid ambiguity ??

Subject: Soil colours
Dear all,
Thank you to those who have recently taken part in my questionnaire - the results are very interesting!
I've been working through some of the questions and many of you have said that describing colour is difficult during logging. As part of my research to standardise colours, I have been researching different colours that can be present within soils. If anyone has encountered interesting or unnatural colours within soils during a ground investigation due to contamination or other sources and knows what has caused the colour, I'd be very interested in including it in my project. Any pictures you have will also be very helpful.
Kind regards,
Sophia
