Hope you can help. I have a well that is 250 deep in hard granite with a 1HP well sitting at 200 ft. When the well was last tested 5 years ago the 4hr run test results shoed that the well was producing 12 GPM. At that time, the static water level was 40 ft.
The problem is that the well now is producing only 240 gallons per DAY.
I suspect that the drop-off in production (which happened over the course of a week) was the result of the following - I installed a new drip irrigation system and the timer malfunctioned which resulted in the draining of 5000 gallons from my storage tanks. I was away on vacation when this happened and the well was overtaxed for a period of 7 days. I did have a pumptec device on the well pump which would have shut the pump off for 30 minutes every time it went dry.
When I got back from vacation, I checked the storage tanks and noticed that they were way low. I thought the well pump had gone out but my local pump tech proved that it was not the pump by watching a ampmeter which was hung off the hot lead on the pumptec. I could see that the well pump was pulling 9.5Amps when it kicked on and would slowly go down to about 9.2 amps before the pumptec detected a dry well and shut off.
I let the well rest for a week (purchased potable water locally for $150/1600 gallons) - when I turned the well pump back on, it ran for 30 minutes and then shut off. I turned it off for 8 hours and ran it again, this time it stayed on for 15 minutes. Now, I am at the point where it runs for about 5 minutes if it is off for 240 minutes. Obviously, the well is not producing much water.
I've had 2 well drillers out and at $16/ft plus $1500 to setup the rig plus pipe, and electrical, a new well (at up to 750 ft) is a very expensive proposition.
I was hoping for any insight or other suggestions. I have not pulled the well head or the pump. I really do not know where the static water level is at this time. Also cannot really determine the well output other than from recording the timing cycles of the pumptec.
Thanks for taking a look.
