Contamination Testing In Leicestershire – Case Study
We were able to ensure that our client was fully compliant with environmental regulations and saved them time and money by carrying out the contamination testing and 'duty of care' processes on their behalf.Get In Touch
Contamination Testing For, Leicestershire Based, DPL Steel Buildings
We were instructed by a Leicestershire based regular client of ours, DPL Steel Buildings, to carry out a contaminated land investigation, including site assessment with sampling work and soil contamination testing for waste disposal. After being let down by a previous contractor, DPL needed waste classification testing for muck away removal of 5000 tonnes of soil from their site in Bottesford, Leicestershire and were on a tight schedule so needed a fast service. We were able to visit the Leicestershire site the following day and carry out a full site survey along with comprehensive soil sampling of the soil being removed from site. This allowed DPL to stick to their schedule, mitigating any delays and ensuring they complied with waste disposal regulations.
The site in Leicestershire was approximately 2500m2 with around 5000 tonnes of soil for muck away. We generally take 1 sample set per 500m3 or 1000 tonnes so for this quantity 5 sample sets were taken. This included 5x 500ml plastic tubs, 5x 250ml amber jars and 5x 100ml VOC jars. Samples are collected in a range of jars in order to analyse the soil for different properties, such as heavy metal and oil concentrations, in order to gain a complete testing of the soil and any potential contamination. Soil samples were taken using an auger and a trowel and were taken from specific locations on the site so as to gain a representative sample of all the soil being removed.
Laboratory Contamination Testing
These samples were then sent to a UKAS accredited laboratory for contamination testing where they were tested for a range of properties. The samples are tested for concentrations of heavy metals, TPHs and PAHs. This is known as a 'Waste Classification Test' as these are considered to be the most important characteristics of soil with regards to classifying it as hazardous or non-hazardous. Since DPL needed results as soon as possible we were able to turnaround their results in just 2 days.
How Our Contamination Testing Helped
Through accurate sampling and comprehensive contamination testing, at DPL's Leicestershire site, we identified the spoil as non-hazardous, allowing them to dispose of it safely and save costs on landfill tax or environmental fines.
When soil waste from construction activity is to be disposed of it must be classified as hazardous or non-hazardous. Current legislation bans the disposal of hazardous and non-hazardous waste in the same landfill so all waste must be analysed to identify its level of contamination for classification. There is also a range of other details that need to be provided to the waste carrier in order to comply with environmental regulations. For example, the correct 'List of Waste' and 'European Waste Catalogue' codes are needed along with details of the activity producing the waste. It is important that these details are accurate and ensuring compliance with the many regulations can be a time consuming process.
