Emergency Well Treatment

Emergency Treatment for Used Wells

If your well has been contaminated or you suspect that it may be contaminated, DON’T drink the water. Contact your local, state, or tribal health department for specific advice. You need to properly disinfect or treat the water and have it tested before drinking/using the water!

If your well has been contaminated (or you think it may have been contaminated), drink bottled water or clean water from another source. If none of these options are available, follow Boil Water Advisory (BWA) guidelines to minimize the risk of contracting a waterborne illness.

Please remember that boiling water that has been chemically contaminated will not provide any health benefits. During a chemical contamination, you should not use the water for any use, including drinking and bathing. Contact your local, state, or tribal health department for specific advice.
