Earlier this year I was approached by a client in Whitchurch who was in the process of developing a large chicken farm and needed sufficient quantities of water to be supplied. I know this area fairly well from past experience. It is extremely difficult to work out the geology of the area as there is so much heavy marl in the area which does create and cause problems when one is trying to work out the depth of the water beneath the ground, never mind the quantity of the water likely to be recovered from the site. Previous to me being approached by the client two other boreholes have previously been drilled, one of which produced between 1 to 2 gallons per minute and the other one I believe was not successful, so I knew I had my work cut out. First of all I did a remote map survey and I found there was very, very little water at normal levels beneath the ground. After discussion with the client it was agreed that I search at a deeper level on which I then started to pick up a supply of water. I immediately informed the client and I was then invited down the the site to firm up my findings. I found two sources of water but they were below the marl clays. The only thing I was sure of was that the water was there, and that it would be in the rock formation and not in the marl clay of which I told the client this, but when dealing with marl clays it tends to short circuit the natural form of depth counting. So I turned all my efforts to concentrate on the rock formation carrying the water and I can then able to give a guide of the depth and the quantity of water recoverable from the site to the client and the driller. A few days later I contacted them and I was informed that they had hit the water at a depth of 288 meters going down to saturation of nearly 300 meters with a quantity of water at 9 to 10 gallons per minute, at a rest level of 30 meters from the surface. The client is at present in the process of getting the water analysed, but depending on the results they may have to use a filtration system which I had already forewarned the client about because of the depth that we had to go to. The client has confirmed that they are happy with the work that I have carried out for them. I can also with my method locate sources deeper than this even into kilometres, this has been confirmed by geologists in the past. Please see the photograph of the site which shows the water going up the rig and through the pipe which when they hit the water it came with such force it actually moved the rig slightly.
