Last week?

I think dey used a hall occupied by a restaurant inside the mall....shoprite is just a store inside the mall.

From this vlf result, a conductivity map of the area was produced.

This was done for better view and assessment. Apologies for not denoting the dumpsite boundaries on the map but it falls at the points with the highest conductivity values.

We promise to give you the best...

This is giving us images up to about 30m deep. And all the profiles being red shows dat the whole area is contaminated.... You can see something like migration (deep red) downwards.

Larwin:
That was d image we got using Resistivity method.... Let me now show you Wat vlf gave us.

Here is the imaging from the VLF profiles

Haba I just hope it's for Nigeria's interest and not baby's selfish agenda

DONSMITH123:
at bolded. The last thing that can never happen again. The worse Oshio and INEC will do is to announce their usual tactics, Inconclusive.

Naxo ó. Make we just dey pray against bloodshed and make d youths give demsef brain.

donphilopus:
Ize-Iyamu is a failure who has already lost the Election. I trust the 'good' people of Edo State. We are not that foolish to vote Lucky Igbinedion in the guise of Ize-Iyamu come Wednesday!

Is it pro Oshiomole u want

Wish I cud read through....

Nice one

DONSMITH123:


boys are not smiling.

Lols, doz guys are somehow now... Dey dnt want to be challenged, dey just want everything to go Dere way. If it's nt working out Dere way dey change d field completely. You won't be surprised if u hear edo election will be held in abuja

APC and Dere military tactics... Not only retraction, dey will see more libeling

Who says it's rough now.... No b all ds fools?

I think dey ve Sabo in Hausa land too

@Lawin. Thanks so much for the info.

You are welcome

@Op in case your thinking of donating boreholes to the Abẹ́òkúta or ogún communities you can contact me.

Where is my abimbawealth

.

Cudnt update today... Busy all through.

DONT THINK IT IS BRO....U USED A SAND OF 35 AND 15K TO SETUP YOUR HOUSE TO ROOFING LEVEL,Y WILL I NEED 3 TRIPS OF SAND TO SETUP 500 BLOCKS

Dats on a hype side really

1Segzy:
Very informative. What do you refer to as full casing? Is there something called half casing. What is casing in general? How far or deep should casing go in a borehole?

Thanks 1Segzy for the compliment.

Casing generally are the pipes that are inserted into a drilled borehole. Here, we normally use pvc casing... I think they use metal casing b4 but was stopped due to corrosion
The pipes are of different thickness and diameter. And the pump is suspended inside it.

What they usually mean by half casing is that, the stable part of the hole won't be cased at all... For instance, let's say you are drilling through a rock, the driller might decide to case just the part where we have soft formations (clay, sand, silt etc) leaving the part with rocks open.

In full casing also called cased down, the whole length of the hole is cased leaving no part uncased.

Me personally prefer casing down for my projects but you should know it's a function of the cost of the project. You as a client might really not know what is going on that is while the no 1 priority in borehole drilling is having a trusted and competent hand on the job.

Another thing is screening. Here holes are made on some parts of the pipe at different depths where we ve aquifer units. This is aimed at allowing inflow of filtered water into the hole at those depths. With this, you won't just be tapping water from the bottom hole.

In general, casing helps to prevent unstable sediments /formations from caving in or collapsing thereby blocking your hole. It also prevent contamination to your water.

Let me use this image to explain further.

I hope this little explanation is helpful.
Thanks
