Hi Simon, The bollards are within or close to the footprint of a former foundry. The site manager was using a CAT to scan for any services in the vicinity and picked up signals throughout an area approximately the size of a car, adjacent to the bollards. There may be a tank or something buried there. But how it is linked to the bollards we do not know. I will be visiting the site tomorrow to have a look and sample the soils. A lot of people from the forum have suggested that the blue mineral may be a complex cyanide, so I am taking that into consideration for the sampling. Kind regards, Cila Gardner ------------------------------------------------------------------------ ------------ Mrs Ercilia Gardner BSc Hons FGS CGeol Principal Geo-Environmental Engineer East Wing Station House Broadclyst Exeter, Devon EX5 3AS Email [log in to unmask] <mailto:[log in to unmask]> TEL: 01392 460 800 FAX: 01392 460 888 Disclaimer This email and any attachments transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.

Thank you From: Contaminated Land Management Discussion List [mailto:[log in to unmask]] On Behalf Of Ercilia Gardner Sent: 05 December 2011 12:27 To: [log in to unmask] Subject: Metal bollards and copper sulphate Hi all We found three metal bollards on the ground with what appears to be clinker or "forge coke" and some striking blue mineral fragments which appear to be something like copper sulphate and fragments of yellow sulphur. Have any of you come across this before? Apologies for the blurry pictures. The site used to be a foundry and the presence of copper sulphate and sulphur minerals is not a surprise. But I have never seen bollards like these before (in sets of three) and I am curious as to whether they are an indication of something buried? Any ideas??
