Ash Remediation Management were contacted by a Midlands based construction firm regarding approximately 1000m3 of contaminated soil that was encountered on their site. It was assumed that this material would have to be disposed of off site with clean fill imported, this however, was not the case.
Ash Remediation Management analysed the contaminated material and confirmed that a bioremediation process would be an effective and viable remediation route. The material was conditioned with compost and fertiliser before being laid on a bunded aeration system. The aeration system facilitated more efficient contaminant breakdown allowing the post treatment material to be available for use sooner. During the treatment phase biopile ‘health indictors’ (e.g. contaminant, O2, CO2 concentration and temperature) were monitored to ensure the effectiveness of the treatment process.
The remediation programme was completed in 9 weeks.
