Dear experts,

i have just received the report of water sample analysis (see attachment).
The samples were taken in Nigeria (100 km from Lagos).

BH-24 & BH 29 are samples from boreholes. It was taken while drilling for soil investigations were on and at a depth of 20m

North TF : it is the surface water from small creek nearby our tank terminal

East and West Pioneer Jetty: water samples from nearby river, which is approx. 5 km from our site.
Warehouse: sample from surface water in small water bodies near our warehouse.

I have also asked the acceptance level as per Nigerian standards, you will see that in the table.

Can you please have a look at the report and give your opinion/advice??

Thanks in advance.

Your attachment did not post. I don't know if it is possible to put attachments on these boards.

Probably the figures couldn't be attached to my previous post.
therefore i have copied the data and pasted them below.
So as mentioned before, the samples were taken at 6 locations:
1- BH 24 = Bore Hole 24
2- BH 29 = Bore Hole 29
3- NTF    = North of Tank Farm
4- EPJ     = East Pioneer Jetty
5- WPJ    = West Pioneer Jetty
6- Warehouse
