My well was drilled today:
Drilling Type = Air Rotary
Well Depth = 505 feet
Static Water Level - 220 feet
Water GPM = 20
Perforated Pipe = 280 feet - 500 feet (20' pipe sections every 20 feet - 100 feet total of perforated PVC pipe)
The well driller said that the 20GPM is "conservative" since they measure the GPM during drilling by taking a bucket and timing how long it takes to fill. He said the well will produce more GPM since the drilling rig is blowing air into the well and this prevents the well from filling normally. He also said that debris can clog the water vains during drilling and that can reduce GPM.
Is the above true?
The well driller claims the only true test is once the well pump is installed one then can get a proper GPM reading.
