How to Fix Well Water Contamination Problems Immediately
If you find that your well water is polluted, fix the problem as soon as possible. You may need to disinfect your water have a new well drilled, re plumb or repair your system. Consider hooking into a nearby community water system (if one is available).
If you have a new well drilled or connect to a community water system, the old well must be closed properly. Consult "local experts" for help.
Procedures for Dealing with Well Contaminants
[See these (non-EPA) step by step guides to correcting problems with well water:
- WATER TEST INTERPRETATION
- COMMON BACTERIA TESTS for DRINKING WATER
- FAILED WATER TESTS - WHAT TO DO
- FAILED WATER TESTS - WHEN to RE-TEST
- WATER POLLUTANT SOURCES
- WATER WELL CONTAMINATION HAZARDS
- FLOOD CONTAMINATED WELL RESTORE & PROTECT
- WELL CASING LEAK REPAIRS
- WELL CASING LEAK REPAIR FAQs
- WELL CONSTRUCTION INFORMATION SOURCES
- WELL DISINFECTION PROCEDURE, POST FLOODING
- WELL SHOCK / CHLORINATION PROCEDURE
The EPA's "disinfect your water" refers not to simply temporary disinfection by "shocking" your well, but more likely to installing equipment to treat the water to assure that it is sanitary.
Dealing with a Persistent Well Contaminant Source
If there is a persistent source of well contamination which you are not able to eliminate (such as by repairing a groundwater leak into a well casing), then the choices are either drill a new well or treat the existing water supply to remove the contaminant. Also see

You might consider installing a water treatment device to remove impurities. Information about treatment devices can be obtained from the following sources:

There are many home water treatment devices. Different types remove different pollutants or impurities. No one device does it all. Also, you must carefully maintain your home treatment device so your water stays safe. For more information, get a copy of EPA's pamphlet, "Home Water Treatment Units" from the U.S. EPA Resource Center or call the Hotline at (800) 426-4791.

Question: well pump leaked oil into the well bore - water smells
(Feb 5, 2012) hkmp50@yahoo.com said:
I reciently had my well pump go bad, and in the process it leaked all the lubricating oil from the pump into the well.
Basicly the bottom of the pump disintegrated, it has been in service since the 70's Is there any way to fix/repair/remove the contaminate? I replaced the pump but smell oil in the water now, is this a health issue I whould worry about?

In my OPINION you sure don't want to be drinking oil-contaminated well water. It could take quite some time and waste a lot of water (and contaminate your piping and water tank) to try to flush the oil out just through your new well pump; if you can't get rid of the odor after running water for an hour or so you might try calling a local well driller to see if they have a more powerful pump that can be used to get ahead of the well flow rate into your well - basically pumping the well out completely once or twice.
Check with your local health department and water testing lab to see if they recommend adding a non-toxic (food-grade) oil dispersant that can help remove oil from the well, but
Watch out: common oil dispersants such as Corexit used by the oil industry are themselves highly toxic and should not be inserted into a drinking water source.
See CRUDE OIL & DISPERSANT EXPOSURE
After pump-out is completed, and after you've emptied your water tank and refilled it with clean water, and flushed your system piping, I recommend taking a water sample to your local water test lab to check water potability as well as to check for oil products.
