My well is at least 210 feet deep and was drilled in the 1960s. It has a 6 inch casing. In 1992, I had the hand pump replaced with a 1/2 HP submersible attached to 210 feet of steel pipe. At that time, the installer pumped the well for 1 hour and got a rate of about 1 GPM. Since then, we've used the well primarily to water a garden. We didn't use it in winter months. The recharge rate has decreased to where it is now less than 2 gallons per hour. I can't find records for this well. The original driller, now deceased, had all his records destroyed in a fire. The state has no records on this well. However, according to a local geologist, it's likely that the well is in a vein of cyanite.

I'm considering having the well rehabilitated using hydro-fracturing. Do you know if this works? According to some websites, the hydro-fracturing success rate is 95 percent, if the well is in a certain type of rock. When successful, the procedure typically results in a rate of 1-5 GPM, although more dramatic increases have been reported.

What do you think?

Thanks for your help.
