Contamination Testing For Waste Disposal
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 tested to identify its level of contamination for classification. There is also a range of other details that need to be provided to the waste disposal company in order to comply with environmental regulations prior to them collecting waste from your site.Get In Touch
Contamination Testing for Construction Waste Disposal - Case Study
When disposing of soil waste from construction work, it is often necessary to test for soil contamination to ensure the waste is appropriately disposed of. This generally involves collecting soil samples to be analysed in a laboratory to classify the waste into a particular landfill class. With tighter environmental regulations being imposed on business activities it is important to ensure that construction waste is properly dealt with to avoid penalties and potential environmental pollution.
Site Visit & Fast Tracked Turnaround - We were instructed by a Leicestershire based regular client of ours, DPL Steel Buildings, to carry out a site assessment with sampling work and soil contamination testing for waste disposal. After being let down by a previous contractor, DPL needed contamination testing for muck away removal of 5000 tonnes of soil from their site in Leicestershire and were on a tight schedule so needed a fast tracked turnaround. We were able to visit site the following day and carry out a full site survey along with comprehensive soil testing of the waste being removed from site. This allowed DPL to stick to their schedule, mitigating any delays and ensuring they complied with waste disposal regulations.
Soil Sampling - The site was approximately 2500m2 with around 5000 tonnes of soil for waste disposal. 5 soil sample sets were taken from testing, 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 waste for different properties, such as heavy metal and oil concentrations, in order to gain a complete testing of the waste and any potential contamination. Soil samples were taken using an auger and trowel and were taken from specific locations on the site so as to gain a representative sample of all the waste being removed.
UKAS Accredited Laboratory Contamination Testing for Waste Disposal
Laboratory Analysis - The soil samples, collected from site were 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.
Waste Characterisation Form - Many waste disposal companies require and completed waste characterisation form prior to collecting waste from site. A waste characterisation form is both simple and complex and generally consists information about the site and the waste being disposed of, as well as, contamination testing to confirm whether the waste being disposed of is hazardous, non-harzardous or inert. For example, the correct 'List of Waste' and 'European Waste Catalogue' codes are needed along with details of the activity producing the waste. As part of our service, if available, we will complete the waste characterisation form of our client's chosen waste disposal company, saving them time and giving them confidence that the information is accurate and the form is correctly completed.
How Our Contamination Testing Helped - Through accurate sampling and comprehensive contamination testing of the waste, 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.
