BS10176:20202 COMPLIANT TESTING
NEW - BS10176:2020 COMPLIANT TESTING TAKING SOIL SAMPLES FOR DETERMINATION OF VOLATILE ORGANIC COMPOUNDS (VOCS)
For clients working in the remediation and brownfield development industries, ALS can provide a range of environmental services designed to meet your analytical needs. If you are looking to optimise your site investigation or remediation project, our range of turnaround times, industry standard suites and onsite analytical tools enable customers to choose an analytical package to suit their project priorities.
ALS Environmental provides a broad spectrum of analytical services for contaminated land to an array of industry specialists including:
» Remediation experts
» Geotechnical Consultants
» Site Investigators
» Environmental Consultants
» Engineering Consultants
The analysis of soils and associated ground waters on brownfield land is driven by a regulatory need and requirement to monitor the levels of contamination that are present on a site. The monitoring is often required to be accredited to UKAS and MCERTS standards with a high emphasis being placed on the quality of the analytical data supplied by the laboratory to the contractor.
We understand legislation plays a major role within this industry and now offer analysis to meet the NEW regulation BS 10176. This standard is intended to improve the reliability of soil sampling by introducing procedures which if followed correctly minimise the loss of volatile organic compounds (VOCs) to atmosphere during and after sample collection.
These approaches allow the soil to retain its original structure and minimise any disturbance. Volatile This recently published British Standard specifies methods for taking soil samples for the determination of VOCs. ALS have developed a range of approaches to comply with the requirements.
Two principal methods of collecting samples are specified within the standard:
- a small intact core sealed to prevent loss of VOCs is taken and sent to the laboratory;
- a small portion of soil taken with a coring device is immediately placed in a preservative (e.g. methanol) in a sealed vial to be sent to the laboratory.
Losses are linked to disturbance of the soil matrix and exposure to the atmosphere. Methanol performs two main functions – it stops microbial degradation and VOCs are soluble in it. Many of these techniques have been used by ALS laboratories throughout Europe, the US and Australia. Our international experience has enabled us to provide practical and pragmatic solutions to ensure you comply with BS 10176.
We have carried out extensive trials to the determine VOC limits of detection using methanol and are able to transport sampling equipment and pre-prepared vials via our standard courier. Whether soil samples are collected as intact cores or preserved using methanol, an extra container will still be required for analysis of moisture content. Additional quality control samples will be needed for each set of soils submitted.
We offer various sampling options below to meet the NEW BS 10176 standard:
» Easy Draw Syringe Sampling Kit for Collecting an Intact Core
» En Core Sampling Kit for Collecting an Intact Core
» Easy Draw Syringe Sampling Kit for Methanol Preservation
» Terra Core Sampling Kit for Methanol Preservation
The Easy Draw Syringe (EDS) sampling kit is provided and allows soil to be collected and retained as an intact core. Using the EDS allows the soil sample to retain its original structure and therefore reduces loss of VOCs.
The En Core sampling kit is provided and allows soil to be collected and retained as an intact core. Using the En Core sampler allows the soil sample to retain its original structure and therefore reduces loss of VOCs.
The Easy Draw Syringe (EDS) sampling kit is provided and allows soil to be collected and immediately extruded into a pre-weighed, pre-preserved 40 ml VOC vials containing 10 ml of methanol. Methanol performs two main functions - it stops microbial degradation and VOCs are soluble in it.
The Terra Core kit is provided and allows 5 g of soil to be collected and immediately extruded into a pre-weighed, pre-preserved 40 ml VOC vials containing 10 ml of methanol. Methanol performs two main functions - it stops microbial degradation and VOCs are soluble in it.
Compliance with this standard will change the way samples are currently collected for determination of VOCs. It highlights the importance of close liaison and cooperation with your laboratory.
We have supporting documentation on BS10176 compliant testing and our client services team can advise you on the next steps.
