TRIAL BORE

Drilling Trial Bore using Telescopic Method with suitable rig to extract water samples of different strata's encountered during drilling to check water quality with respect to Physical & Chemical Analysis, Heavy Metals such as Iron, Nitrate, Arsenic, Fluoride, Selenium, Uranium etc. The payment for testing water sample will be paid extra as per the quoted rates against relevant items of this bid. However the rates includes analysis of sand of all strata from where the water sample have been collected. (It should be ensure that the water sample is collected by an officer of rank not less than SDE)
