CUSTOMER INSPECTION/COMMONUICATION DETAILS

Safe drill depth form approved by Hamid. 015-DN-027. Rev-B 25-01-2024.

Hi Hamid,

As discussed we hit leachate at around 25m on well W4-31 and couldn't get proposed depth of 36m. The well kept collapsing to around 29m so we have cut the well and installed to that depth.

Thanks Richard.

Approved.

Kind Regards

Hamid
