Dirty well water after rain

After a heavy rain our well water turns yellow/brown, and occasionally will lose pressure. During heavy rains, standing water collects near the well area. Any suggestions on causes for dirty water after a rain, and how to clear up?

Only have experience with municipal systems on wells, but dirty water after a rain isn't a good sign. Usually means surface water is infiltrating the well by means of the well head. You are basically pump water that has run off and drained into your well, not ground water.

There are several good well - pump guys on this site. I'm sure they will post more info....

Cool

Do you have a shallow well (25' or less) or a deep well?
How far is it from the nearest part of any septic system (if you're on one)? Is there a farm, fuel (gas station), or industrial site near by?
As notuboo said, you are getting surface water contamination into your water supply. You should correct this as soon as possible.
Do NOT drink this water or cook with it until you have it tested (Health Department) and the problem corrected.
If the well is occasionally losing pressure, you probably have a leak on the suction (well) side of the pump, and it is probably near the surface at the well.
If you have a shallow well, I would look at driving or washing a new one down.
If you have a deep well, you need to pull it and repair the line between the submersible pump and the home.
Additionally, after you have the well problem corrected, you should decontaminate your water lines in the the well and house.
To decontaminate your water supply system, pour several gallons of bleach down the wellhead.
Run the water through your house until you have bleach water running out of all faucets. Let sit about 12 hours, or at least overnight. (This will decontaminate your water heater, also).
Then, run the water until it flushes all bleach-smelling water out of each faucet.

Dirty well water after rain

Hi,
If your well is drilled into an underground aquifer or river, you may just be seeing the effects of a lot of rain water runoff, especially if the aquifer water level is down due to recent droughts, etc.
If this is the case, the solids should settle out and the water should clear up.
As Mike said, you may need to decontaminate your system and have the water checked if there is some doubt it may be clean.
The pressure loss may be solids plugging up the pump suction screen. Does the pressure loss seem to be tied to periods when the water is dirty?
Does it happen after there has been a heavy demand placed upon the system? Let us know.
Best regards,

Response to OldGuy & Pumpman:
Thanks for the responses. The dirty water is only the day after a heavy rain, which is usaully an all day rain saturating the ground. The low pressure problem is also only when after a heavy rain when the water runs dirty (but not always happening). We have had severe droughts here during Spring & Summer in SC for the past 5 years. I'm not sure of the depth of the well, but will investigate. The well is approximately 50 yards from the septic, and there are no farms, fuel, or industrial sites in the area.
